AWS Services Overview | Introduction To AWS Services | AWS Tutorial For Beginners | Simplilearn

0:08 hello guys uh so today I would be covering up uh AWS services and uh the important AWS Services definitions and I would be also showing you a demo on those services but before that I would request you to subscribe our Channel and also like our video you can find the link just below at the right side of this video let's continue let's look into what we have in our upcoming slides so what's in it for you I would be covering up what is AWS the Amazon web services what are the benefits of uh using AWS as a cloud and the different AWS services that would include compute service storage service database service networking service Security Service management tool service developer tool

0:53 service likewise and then I would be covering up demo on those essential AWS Services let's look into what is AWS AWS is a broadly adapted Cloud platform which offers several OnDemand operations like compute power database storage content delivery Etc and that helps corporate scale and grow AWS Services can be used to create and deploy any application in the cloud for example it provides services over the Internet just like worldwide web and AWS is the largest Cloud platform available that you can use for either creating the application creating the databases likewise the other features also you can

1:40 use simultaneously now what are the benefits of AWS the first is it is easy to use for using the AWS you require the good internet connectivity and then you can actually brows it using the web console and also you can use the command line interfaces as well second flexibility AWS offers you a flexibility so that you can actually change or tweak your Solutions whenever you require reliability so with the help of the Redundant infrastructure across the globe the AWS gives you the reliability that any application or any databases if you're running on the AWS that would be

2:26 basically up all the time and there will be no or very less downtime then comes the scalability so scalability is one of the important features of AWS and in that case you can actually scale up your resources at any time you require so for example if any of your application is over utilized and you require more resources to run your application you can do that on the Fly then comes cost Effectiveness so AWS is a very cost-effective platform because here whatever the service that you use that is charged on a per hour usage only so you don't have to pay the complete cost like you do when you procure the infrastructure in the data centers you

3:11 don't have to uh basically pay for the complete package or usage of the service you just have to pay for whatever time duration that you have actually used that service and the associated charges with it and that makes the AWS a very cost- effective solution then comes the security so AWS is a secure platform and lot of measures have been taken so that the security can be enhanced and upgraded in the AWS so from the infrastructure level the AWS have a very high level of security that is implemented and from the application and the solution perspective it gives you lot of features where you can actually apply the security as per your requirement onto your applications

3:58 coming to the AWS servic so essential AWS services are compute storage database migration networking in content delivery developer tools management tools Media Services machine learning analytics security identity and compliance mobile services application integration arvr which is augmented reality and virtual reality customer engagement business productivity desktop and app streaming internet of things which is iot now let's look into the compute service which is one of the widely used service on the AWS and what does the compute service do these Services help developers build deploy and scale an

4:45 application in the cloud platform that is ec2 Lambda elastic container service elastic load balancer light sale and elastic bean stock these are the services which lie in the compute service section only one of the most widely used service within the compute section is ec2 which stands for elastic Cloud compute it is a web service that allows developer to rent virtual machines and help to resize the compute capacity so here what you can do is you can run the virtual machines and you have the Privileges to select the type of operating system that you want uh should be running on your instances or on your virtual machines and likewise later you can customize as per your

5:32 requirement Lambda is a serverless compute service it is also responsible to execute code for a specific application so those who are from the development background they can focus more on creation of a code they don't have to create a server manage it instead they can use a Lambda where you they can deploy their code directly onto the Lambda server then comes the storage service now couple of storage services are S3 glacia EBS which is elastic block Storage storage Gateway now AWS provides web data storage service for archiving data also its main advantage is disaster data recovery with high durability let's

6:19 look into some of the essential storage services and one of the most widely used storage servic is S3 which stands for simple storage service in the simple storage service what you need to do is you have to create a bucket and in that bucket you have to put the files in it so S3 gives open cloud-based storage service which is utilized for online data backup then comes the EBS which is an elastic block storage now you can understand EBS as a virtual hard drive also which attaches with the ec2 and it provides High availability storage volume for persistent data it is mainly used by Amazon ec2 instances then you have the database Services AWS database

7:06 domain service offers coste efficient highly secure and scalable database instances in the cloud and some of the database services are RDS which is a relational database service Dynamo DB the non-relational or no SQL or no SQL database service elastic C and Amazon red shift now one of the essential database service is the Dynamo DV it is a flexible nosql database service which offers fast and reliable performance with no scalability issues it is fast reliable highly scalable and suitable for small scale applications like mobile applications gaming applications or anything with respect to

7:53 the Internet of Things devices there the dynamodb is uh most wiely used or suitable then comes the relational database service that is the RDS which is a structure database service it is a managed distributed relational database cloud service that helps developers to operate and scale database in a simple manner so RDS has different vendors platform with respect to the database U usage and that includes the post gr SQL MySQL then you have Oracle Microsoft or Ms SQL and uh they have their own customized database as well that is called as the Amazon Aurora along with

8:39 that they have a Maria database or Maria DB as well so these are couple of vendors that give their database engines uh that you can use on the RDS now coming to the networking Services it offers a highly secure Cloud platform and helps in connecting your physical Network to your private virtual ual network with high transfer speed now some of the services in the networking and content delivery are VPC which is a virtual private Cloud a very important service in order to make your applications or uh Services more secure roote 53 which is a DNS mapping Service Direct Connect which directly connects with the AWS services and with your data

9:26 centers and the cloud front that is basically Ally a Content delivery service now coming to the VPC or a virtual private Cloud it helps a developer to deploy AWS resources such as Amazon ec2 instances in a private virtual Cloud so that you can actually make your ec2 isolated or make it more secure and even you can make it for a public access also depends on the administrator that how they want to customize it so the complete control of a VPC and its networking is with the admins then comes the roote 53 service it is a web service with highly available domain name system or the DNS

10:13 that helps user to Route software by translating text into IP address and that is why it is called as a DNS mapping service and that helps you to use your domains or the external domains pointed to the AWS services in case if you use AWS for hosting your websites or the applications note DNS translates text into the IP address now coming to the developer tool services it helps a user build deploy and run an application source code automatically it also updates a server and instance on the workload so first is the codar code build code deploy code pipeline so codar it is a service designed to manage application development at a single place here developers can quickly

10:58 develop build and deploy applications on AWS so all the manage app development can be done with the code star code build removes the hassle of managing physical servers and helps developer build and test code with continuous scaling so security identity and compliance Services helps in monitoring a safe environment for your AWS Resources by providing limited access to specific users so in case let's assume that you have to give an access to someone but with limited privileges you can primarily use IM am in that case and if you want to make U your applications or um deployments more secure then you can use uh these services like uh KMS IM

11:46 Cognito uh WF which acts as a firewall now the IM service which is the identity access management is a framework that helps in maintaining access to aw service services in a secure way so what happens is that the admin who has the complete access of the ads console provide access to users and there can be different users and they would have the privilege accesses uh defined by the Admin so what type of permissions the admin gives them uh they would have those limited access on the AWS console KMS enables users to create and manage the encryption key that are used for encrypting data coming to management

12:32 tool services with the help of management tools using the service an individual can optimize cost minimize risk and automate all the resources running on the AWS infrastructure efficiently so with the management tools you can monitor the resources application it's uh its tools and the utilizations and along with that you can scale up scale down the resour ources likewise with the help of the management tools you can also do the auditing task so one of the essential service in the management tool service is the cloud watch it is a monitoring tool for AWS resources and customer applications running on AWS platform so let's assume

13:20 that you have used ec2 Dynamo DB S3 RDS and you want to monitor those resources you can use the cloud watch that can can give you the results coming to the cloud formation this service helps you in monitoring all your AWS resources at one place so that you can spend minimum time in managing those resources and maximum time on developing the application so with the help of the cloud formation you can deploy the entire solution with the help of creation of a template you just need to create one template and you have to deploy it the rest of the things will be done by the AWS and hence it is a kind of an automation task only now

14:06 let's look into the demo of some of the essential services so we'll start with the ec2 and I have already logged in into my AWS account so where exactly you can find the ec2 just click on the services under the compute section you can find the ec2 ec2 stands for elastic Cloud compute service primarily used for creating the virtual machines so I'll click on the service and quickly I'll show you how the virtual machine is created and how we can basically access it so I would be creating one virtual machine or an instance with the Windows operating system so here you can see there are three instances which are already running let me create another

14:51 one you have to click on launch instances and here you have to select some configuration details so most of the configuration details I'll be taking as default and wherever it is necessary I'll be making the changes so first of all you have to select the operating system in the form of Ami and I would be looking for Windows uh 2016 and then you have to select the type of instance with respect to the CPUs number of CPUs and the memory capacity so I'll go with t2. micro which is a free tier eligible instance in the configure instance details the rest of the things we'll

15:38 keep it as default as of now click on add storage this is a basically the virtual hard drive or the EVS the elastic block storage that is attached with the ec2 instance so primarily it is giving us 30 GB of space without any additional cost we can leave the tax as blank click on configure security groups and here you can see that the RDP Port is by default open which will actually allow us to RDP or to have a remote connectivity of our instance click on review and launch now

16:26 to give an authentication or to provide an authentic apption we should have a key pair with us so that the AWS can understand or can tally the key pair and give us the access so I already have a key pair created what I'll do is I'll create a new key pair for this instance and put a random name let's say I put it something like demo download the key pair and make sure that you keep your key pair in a safe and secure place click on launch instances now you will see that there is an instance ID that has been created which is a number alpha numeric number that is randomly given by the

17:11 AWS you can name your instances so let's assume let's say we name our instance as Windows 2016 click on Save and the AWS deploys our instance on a respective infrastructure it gives us the IP addresses the public IP and the private IP which is an internal IP and we have to access the instance from the public IP only so now to access that instance we have to open up the RDP put the public IP click on

18:04 connect and when it asks you for the authentications you put a username as administrator and the password you have to generate by providing the key so click on connect and then uh you have to click on RDP client here you have to get a password so click on get password browse and when you click on browse you have to provide demo. PM file so it should be in the download section here itself just provide that key pair and it is going to give you the password in the encrypted format decrypt your password copy that and then provide those details to the RDP client click on okay

18:53 and now it should allow you to log to the instance let's wait for the Windows to appear so here you can see that we have uh logged in into the windows instance the windows 2016 screen is available in front of us if getting your learning started is half the battle what if you could do that for free visit scaleup by simply learn click on the link in the description to know more in this particular demonstration I would be explaining you about how to use a storage service specifically the S3 service which is most widely used service under the storage section now the S3 stands for simple storage service primarily used for storing the objects and the files and uh what we need to do is we just have to click on the S3

19:39 service under the storage section so when you click on S3 service um you have to create the buckets inside the S3 and the buckets are the places where you keep your folders or you upload the files that are available on your systems so so here if you'll notice that the S3 service is a global Service that means it is irrespective of the region and uh the buckets when you create they are created in a specific region now what is the benefit the benefit is that if you create a bucket in different regions all those buckets in different regions can be viewed from a single dashboard and uh you don't have to

20:24 change the region again and again to view the S3 buckets so what you need to do is you have to click on create bucket and here you have to specify the name of the bucket so let's say I put something like demo AWS and uh that's the bucket name I'm going to select now make sure that the bucket name starts with the lowercase and it should be always unique now why it should be unique because since S3 is a global Service so it may be that somebody else could be using your the name that you have provided so it should be always unique otherwise it will not be allocated now you have to select a region and that would be let's say I go

21:09 with the Ohio region and uh in the bucket settings you can basically change and configure these settings according to your requirement by default uh when you create a bucket it blocks all the public access from the bucket so when you have all public access blocked no object can be viewed from the S3 Bucket from a public network or from or by anyone else and hence uh in order to view the objects or the or the files in the bucket you have to unblock or uncheck this option so that first of all you make the bucket accessible from the public network likewise you can customize as per the requirement and

21:56 then click on acknowledgement the rest most of the things we'll keep it as default and click on create bucket now it says that the bucket with the same name already exist so that means it is not a unique name somebody else might have been using this name so I'll try to keep it more unique and I'll try to assign some number so let's say I put something like 987 and it says it is already existed let's say 9876 and then click on create bucket now if it creates a bucket that means we have been allocated with that bucket name so let's wait for wait for a minute to get that bucket created so that happens quickly and you can see there are a couple of buckets already created here and these buckets

22:43 can be viewed in a single dashboard so some of the buckets are in Mumbai region some of the buckets are in Ohio region but they are available in the same or a single dashboard so I'll open up the bucket that I have recently created and I'll try to upload some documents now what you can do is you can create a folder also inside the S3 and when you create a folder you can upload the objects accordingly otherwise you can directly also upload the objects so click on upload and we will upload any random file from my system onto the S so I'll uh basically file and then click on upload

23:28 now it is uploading my object from my system onto uh the S3 bucket and now it has successfully done so it says the message is successful now in order to validate I will click on the bucket from the S3 service and view this object now you can see here is my bucket so I'll just open up this bucket and uh these DNS records. CSV file is available with us now the S3 is not only limited till storing the objects or the files it has many other functionalities and the features also like you can enable versioning you can host a static website on the S3 along with that uh you can have a

24:14 cross region replication enabled so that you can have a high availability of your objects or you can have a redundancy of uh your critical objects in different regions so likewise there are more features um that would be covered up in the detail section of an S3 service now coming to another section of uh the essential services that is the database now here you can see I have a database section in the AWS and it has multiple service within in uh the RDS is there Dynamo DB is there elastication and the other database services are there uh so I would be showing a demo on the Dynamo DB which is a nosql database

25:00 now when we say it is a nosql database that means it is a non- relational database service where we can create a database table directly from the web console we don't require a separate database engine uh like uh in the case of RDS and uh in the tables you can insert the values and view those values directly from the AWS dashboard itself so it says Amazon Dynamo DB is a fast and flexible no SQL data database service primarily suitable for iot and web gaming and other mobile applications so what you need to do is it is a straightforward uh database service which is which can be accessed while creating a table itself and it's a compute based database service that is

25:46 the reason that it is more fast so click on create table and what you need to do is you just have to put a table name so I'll just put something like test and uh in the partition keys so these partition keys are unique entities so what you need to do is you have to specify a partition key so I'll put something like ID and the string instead of string I'll use a number likewise I can add sort Keys Also let's say I put a name and the name should be in the string format now these are the unique entries these are the fixed entries in the table and after that we are going to

26:33 put the attributes and in the attributes the data will be inserted so what you need to do is rest of the things we'll keep it as default as of now click on Create and here you can see the table has been created the test table has been created now if I click on the items so you would see that it has the sort Keys available the the ID and the sort key associated with that that is the name but it does not have any entry because we have not added any value or the attributes so how we can add or insert the values in this table that can be done many ways you can enter manually you can use the help of CLI to enter the large chunk of data directly uh upload it onto the Dynamo DB

27:21 table and also you can use the apis also in order to insert the data inside the table so what you will do is we will click on create item and in the ID we will put some value let's say number one string uh let's say we put something like uh we will go with a random name so instead of putting any name we'll put a value like AB BC D that should be fine and then we will insert some attributes so let's say I put string as rank and I'll put something like rank two and then click on save so here you

28:07 will see just refresh the database table close it and open it up again click on the items now here you can see the ID one name is ABCD got the rank two likewise you can click on create items let's say the serial number of or the id2 name let's say we put something like uh we can go with XY Z any random thing put it up as number rank and let's say this particular value got a rank three likewise you can add some more items string let's say you put something like

28:52 hjk and you put a rank let's say it's a rank number one holder rank one holder right so likewise uh this is just an example likewise you can add the attributes as per your need and U the table can be filtered out based on the attributes also so if you have to search some values in the Dynamo DB table so you can always use filters uh to basically search the values uh inside the table apart from that the Dynamo TB table has lot of other functionalities um uh it can be basically uh you can have a backup of a table created in the Dynamo DB table in

29:38 the Dynamo database and then you can retrieve or recover the data by restoring the backups from the Dynamo DV this database can be created in the cluster format also so these are couple of features uh that you can use with the Dynamo DB now let's move into the next section now coming to the networking services so there are some of the networking Services which are very useful and uh that includes a VPC which is a virtual private Cloud cloudfront Route 53 API Gateway Etc now I will uh basically demonstrate about the roote 53 Service uh in this demo so in the roote 53 is basically a DNS mapping service so what you can do

30:24 is let's assume that you are hosting any web application on the server and you want to Route the domain traffic onto those servers you need to have the help of root 53 to do that so what you need to do is you just have to click on root 53 service and from this service you can register your domains also otherwise if you have domains purchased from any external site you can point them to the root 53 name servers also so first of all in the root 53 you have to create a hostage Zone so there is already one hosted Zone all created now when you create a hosted Zone you have to specify the domain name so let me show you I have one dummy domain this is the domain uh that has

31:11 been defined so what you have to do is when you click on create hosted Zone you have to put a domain here you can see example.com likewise you have to put your own domain and uh click on the public hosted Zone click on create hosted Zone and it is going to give you four name server now those four name name servers have to be updated on the platform from where you have purchased the domain so that is mandatory in order to Route the traffic to the rote 53 service right so here you can see I already have a hosted Zone created for a domain and it has given me four name servers these are the name servers and these name servers have been

31:57 updated in a record set from where the domain has been purchased right once it is done then you have to Route the domain traffic to a server so what you have to do is you have to click on create record and in the create record you have to specify the IP address or you can use the alas also where the traffic should be routed to where your application is hosted at so ideally it is a server details and it exists with certain policies also so you can see some view existing records so here you can see this particular domain is routed to

32:44 a DNS value which is hosted in the elastic bean stock instead of that you can put an IP address of the ec2 instance also you can use the S3 URL also you can use the cloudfront URL also so likewise what would happen is that the domain traffic will be routed to the server where actually the application or a web application is hosted at now I'm using a routing policy as simple routing policy that means all the traffic should be routed to that particular domain whereas there are other routing policies also in the Route 53 that includes the weighted routing policy which acts as a kind of a load balancing geolocation routing policy multivalue answer routing policy and then you have redundancy based routing policy which is a failover one so likewise you can select as per

33:31 your requirement so what you need to do is you just have to click on create records uh you have to specify you have the domain so you have to specify any uh particular info you want to put before the domain otherwise you can leave it as blank and in the record type let's assume that you are using an IP address of a server where uh your web application is hosted at so you can basically use a routes traffic to an IP V4 address and put an IP address make sure that you put a public IP address or the elastic IP address attached to your instance in case if you're are not using any particular IP address or the URL you can use the Alias also so likewise uh the records can be created along with that um the Route 53 Services used for domain

34:18 verifications also like uh if you want uh the email services on onto your web application then you can basically verify your domain directly from the Route 53 service you can uh get the verification done for the SSL certificate creation for that also the records will be directly created from the rote 53 service because it is actually managing or hosting your uh domain now with respect to the security services uh the most widely used service is the IM am which is identity access management that lies under security identity and compliance so in from the IM you can create the users uh whom you want to give an access to your AWS console you can create groups and you can add multiple users in that group

35:03 give them the permissions you can create the rules also so that multiple Services can inte interact or integrate it together so how the IM is used uh click on the IM am service and I'll show you how a particular user can be created and U how the user is basically uses the credentials to access the AWS console now the IM dashboard is open and uh when you open up the IM dashboard it gives you the URL so this is the URL through which uh the user has to actually access the AWS console by providing the user credentials now how the users are created just click on the users and U here you just have to click on add user so I'll create one sample user let's say

35:49 I put something like sample user and what type of an access you want to give that particular user do you want to give a programmatic access which is primarily the CLI access or you want to give the AWS Management console so right now we'll go with the AWS Management console access now do you want an autogeneration of the password or do you want to customize the password so let's assume that we customize the password so put any value make sure the password meets all the criterias and uh then click on next permissions now what kind of permissions you want to give to that user let's assume that you want to give an access of a particular service only to that user so you have to actually search you have to actually search a policy for that particular service uh that can be

36:37 given an access to a user otherwise if you want to give an admin policy or the admin access to that user you can search an admin policy there so the permissions are important otherwise the user would not have privileges to access um the AWS console so we'll attach the existing policies directly so click on it and here let's assume that I want to give an admin access to that user so I'll just click on the admin access now to a particular user you can give multiple policies also it is not necessary that you have to give only a single policy so you can provide a multiple policies to the users also now click on next tags let let's make the tags blank click on review and create a

37:23 user now you'll see that our sample user would be created and to access the console we'll just copy this URL which has the account information as well that is the account number so copy the link or you can copy the complete URL log out from the root account and then paste the URL that was copied from the console and then we have to give the user credentials so we'll put sample user as

38:11 the username and the password that we provided while creating the user click on sign in and if it is correct then it should allow us to log into the AWS console while asking the password change so we'll change the password confirm password change and now it should allow us to login into the root accounts AWS console with the admin privileges now the next service is the monitoring services and under the monitoring Services uh primarily the

38:56 cloudwatch uh the cloud trail the cloud formation these are some of the services that are most widely used now the cloud watch is a service which is primarily used for monitoring the metrics primarily of the servers like for example if you create an ec2 instance and you want to uh basically watch out for the metrics associated with the CPU utilization or uh the storage utilization the network in network out all those information you can get it from the cloud watch now Cloud watch is not only related to monitoring the metrix it can generate the alarms also and U here you can get the events also generated which uh or the events that can be created which can trigger the Lambda function as

39:43 well so what you have to do is you just have to click on dashboard so iing metrics are viewed uh with the help of the cloud watch so first of all you have to create a dashboard now you have to put a dashboard name let's say I put something like monitoring ec2 click on create dashboard now how do you want the reports to be published you have to actually select a widget I want that okay the report should be visible in the numeric form so I'll select a number now click on the dashboard that was created and

40:29 uh let's again add the widget and here uh we'll select the metrics primarily for the ec2 per instance metric so we have one single instance running now there are 14 metrics available for that particular instance now I would be looking for the CPU utilization for this particular instance so I'll just select for the CPU utilization and it is going to give me some information about what is the current CPU utilization of the that particular instance so that is somewhere around 29.3% uh the CPU utilization has been done for the single instance that is running in my ec2 dashboard so likewise you can add some more metrics and view them in this particular dashboard and the cloudwatch will keep on publishing the data uh at a refresh interval of 5

41:17 minutes that is uh the default value so that was with respect to the AWS essential Services guys uh thank you for watching our video hi there if you like this video subscribe to the simply learn YouTube channel and click here to watch similar videos to nerd up and get certified click here
