AWS Services

So I hope you people have got a clear variation of AWS and Azure. So now let's go a bit deeper into the console through its AWS services.

As discussed in the previous concepts, this AWS is the best cloud platform to offer various cloud services to the people. So lets us discuss those services one by one in detail.

Let's start discussing the services with EC2

EC2 instance:

It is difficult for one to predict how much computing power is required for an application to launch. And It can be any of the below two scenarios:

• It may be overestimating than the required usage (stack servers may be wasted)
• It may be underestimating than the required usage (there is a chance for the application to get crashed)

So to overcome these kinds of problems we use instances. Before going to know what exactly an instance, lets first know

What is an instance?

An instance is a virtual server for running the application on Amazon EC2. In other words, it can also be considered as a tiny part of the large system. Moreover, this tiny part consists of the virtual hard drive, network connection, OS and so on. And this large system supports multiple tiny systems. And each of these tiny parts is called the instance.

Why Amazon EC2?

Taking the domain and some space is not enough for the website. Because even though you have taken some as per your requirement there is a necessity for the person to update the security patches. In some cases, there is a need for separate software to be installed to support the current security updates. So the person needs to install this recommended software first and then and update this security patch.

Moreover, it is not a one time task. So in an organization, a person needs to be dedicated for all these works. And if its a large organization, then it required a team to perform all these tasks. But today companies were thinking to minimize the manpower and automate the things as they can. And in such a case, Amazon EC2 came into existence to overcome this problem. Moreover, with this Amazon Instance, you can concentrate on coding rather than the infrastructure.

So till now, we have the theoretical explanation of EC Instances. So now let's show the instance creation practically.

While creating an instance, we will found some new terminologies. And we will discuss them in the next topics.

After signing in the account follow the steps shown below

step - 1 :

As mentioned to you earlier, this Vendor provides the services at various places across the globe. So after logging into the account, you people can select the nearest availability reason from the downtown and then start creating the instance.

step - 2 :

In the services tab, go to compute and then move on to EC2.

 

step - 3 :

Click on Launch Instance

 

step - 4 :

In this step, you can see the various tools that are available on the platform. And select the platform that you require.

 

step - 5 :

select the instance type and then click on Configure Instance details

step - 6 :

Select the required number of instances. And also this platform allows you to add the advanced details (Immediate software installation after the Image gets installed). But in this case, I'm moving with the default features and then clicking on Add storage.

 

step - 7 :

select the required storage of the Operating system that you were installing. By it contains 8GiB storage and we can extend up to 30GiB. But here, in this case, I'm moving with the default storage and just clicking on Add tags

 

step - 8:

Add some tags in the form of Key-value pairs and then click on the configure security Group. And we can add the tags by clicking on Add tags

step- 9 :

In this step, we need to configure the security groups. These security groups were nothing but the firewalls. So in this step, we will create the security group as shown below.

 step - 10:Check the configuration details that you have given in the previous steps. And it allows you to edit the configurations in any. And once you checked all those then click on Launch.

step - 11:

In this step, you need to select the key-value pair. So here on the new pop- up select create a new key-value and then provide any name and then click on download Keypair.

step - 12 :

Once you click on download, then you will get the .pem file. And once you get the .exe file then click on Launch Instances.

 

And Once you launched, you can see  the following screen

So, you can check your instance in the instance tab as shown below

 

And I hope you, people, you have successfully launched an instance. And if you people struck up anywhere feel free to contact AWS online training

Since we have successfully launched an instance, we will now connect to this instance.  And in order to connect to this, we need a putty Instance. Click here to know the Putty Installation.

So after converting the .pem file to PPK file, load the .ppk file using the Putty session. Then you can see the  following screen

 

Provide the username as ec2-user. Moreover, different images have different user names. For instance, ubuntu images have ubuntu as the username. So click on Connect on the Instance page to get the username.

And once you have provided the user name, then you will be entered into the following screen If you too can see the above screen like this, you were successful in connecting the machines

How does EC2 Works?

Amazon Ec2 is a web framework that offers a highly secure, re-sizable computing solutions within the cloud space. This framework is responsible for developers to make the web cloud computing easier. And this web service infrastructure allows you to set up the computing capacity as smoothly as possible. Moreover, it gives you insights and provides full access to computing resources. And this enables you to run the Amazon Cloud Environment. Besides depending upon the requirement this framework allows you to scale the computing capacity. Further, this framework allows developers with different tools that can withstand failures.

AWS pricing model:

Moreover, these Ec2 Instances works under different pricing models. So lets us discuss them in detail

As we discussed earlier EC2 free tier allows the 750hrs. of t2.micro instance usage per month. Moreover, after you signup into the account, this free tier is valid for one year.

Spot Instances:

A spot Instances is an unused EC2 Instances. Moreover, Amazon EC2 sets the stop price of each instance in each availability zone. And this price varies according to the time and the availability zone.And this hourly price is known as Spot Price. Besides EC2 adjusts the prices on the basis of demand and the long term supply. 

On-demand Instances:

AWS on-demand instances are the virtual servers that run in AWS Elastic Cloud compute (EC2) (or) AWS Relational Database Service( RDS). We can purchase this at a fixed rate per hour. On-demand instances are suitable for the applications with short term and irregular workloads for uninterrupted service. And this suits best for Ec2 application development and testing the applications.

Reserved Instances:

These instances provide a significant discount compared to on-demand Instance pricing. These instances are not the physical instance, but we can apply the discount to the on-demand instances in your account. Besides, these on-demand instances must match certain criteria to avail of the discount in the billing account. In this instance type, you reserve the instance for the specific time of one (or) three years. Besides this instance has the three payment options like No upfront, partial upfront as well as the full upfront. Here the upfront is inversely proportional to money. i.e the greater the upfront, the lesser the cost.

Features of Instances in AWS :

• Instances consist of pre-configured templates called Amazon Machine Images (AMI). This wraps everything that you need for the server including the operating system.
• This platform offers multiple options for configuring the memory instance, CPU storage as well as networking. Besides this platform enables the various instance types for the user
• Since the instances use the Key-value pairs the instances were very secure.
