How To Create Your Own First Amazon EC2 Instance?

It is tough to identify the computing power one needs for a particular application that’s been launched recently. There can be two possible scenarios here – either you are overestimated and buying resources that were not needed at all or you could be underestimated that eventually lead to the crashing of an application. Here, in this blog for Amazon EC2 Instance, we will discuss the key concepts related to EC2 Instance and how to create or launch your first own EC2 Instance. Technically, Amazon EC2 is a web service from Amazon that offers resizable computing services in the cloud.

What is Cloud computing?

Cloud computing is a model for enabling ubiquitous and on-demand network access to configurable computing resources like networks, servers. Storage, apps, or services  can be acquired or released quickly with minimum management efforts or service provider interactions. With cloud computing, you can always access resources through an internet connection over the web. Furthermore, clouds are majorly divided into three broad categories: public, private, and hybrid clouds.

Type of Clouds

In the case of a public cloud, services managed by an organization are open for use by the general public. In the case of a private cloud, services or IT infrastructure are shared within an organization only. Hybrid cloud is a mixture of the private or public cloud where a few services are made public and rest can be kept private based on the requirements.  Further, there are three services are given within a cloud. These are IaaS, PaaS, or SaaS etc.

Service Models of Clouds

  1. Infrastructure as a Service (IaaS) – This service model offers resources like storage, computing, networking capabilities etc using virtual servers like Amazon EC2 instance or more.
  2. Software as a Service (SaaS) – Here, you can use software apps within the cloud like google apps or Microsoft office 365 etc.
  3. Platform as a Service (PaaS) – Here, you can share platforms to deploy custom apps within the cloud like Heroku, AWS Elastic Beanstalk etc.

What is Amazon EC2 Instance?

EC2 Instance is a virtual server in Amazon web services terminology. EC2 means Elastic compute cloud where an AWS subscriber can add or provision a computer server in the AWS cloud. This is an on-demand EC2 instance offered by the AWS where the virtual server can be rented by subscribers on an hourly basis and use the same for application deployment.

What is Amazon EC2 Instance

EC2 Instances are charged on per hour basis based on their type and the instance chosen. These instances are suitable for multiple business needs and you can terminate them when not needed. This is an on-demand instance where you can save huge on costs by releasing them whenever not required.

With Amazon EC2 Instance, you can configure multiple virtual servers together, add the security or network settings, and manage the storage. It helps you to develop or deploy apps much faster than your expectations. It allows you to scale up based on business needs and provides you with the ability to handle varied needs of your business as well. Before we go a little deep into discussion let us first discuss what is AWS and how to get started with the AWS?

Features of Amazon EC2 Instance

The Amazon EC2 Instance provides the following features that every AWS developer or user should definitely learn.

  • It will provide you with virtual computing environments known as instances.
  • It has a preconfigured template that is known as the AMI or Amazon Machine Images that are further needed for the server.
  • Multiple CPU configurations, storage, memory and network capacity for your instances is known as the instance types
  • It will secure login information for different instance with the help of key pairs.
  • Strong storage for the temporary data that will be deleted once instances are terminated.
  • Persistent storage for data using Amazon ESB volumes.
  • It will give multiple physical locations for your resources that are further known as the availability zones or regions.
  • A firewall to specify protocols, IP ranges, ports to reach the instances with the help of security groups.
  • It can give static IP addresses for dynamic cloud computing then is known as the elastic IP addresses too.
  • There are metadata or tags that are assigned or created to Amazon EC2 resources.

You must now be thinking of how to access the Amazon EC2 instances. There are two popular techniques for the same. These are Command Line interface (CLI) or AWS tools for Windows Power Shell etc. Further, there are two types of instances in Amazon EC2 virtual server. These are Reserved Instances and Spot Instances.

You just have to pay for needed instances without any commitments or upfront payments. In the case of Reserved Instances, there are reserved for one day or longer. You could pay for these instances even at hourly basis. Next is Spot instances, where you request for unused instances that will lower down the costs significantly. In the next section, we will be discussing how to create your own first Amazon EC2 instance.

How to create an Amazon EC2 Instance?

To create or launch an Amazon EC2 Instance you need to follow the given steps one by one –

  1. For this purpose, you first need to go to the EC2 dashboard and click on Launch instance button from there. Here you would see a create a New Instance Window.
  2. Select the best combination of OS and Apps and you will get an option to select the instance type further. Also, you need to select the geographical region where you wanted to run the instance.

  6. Here, you need to add key and value both and continue further.
  7. As soon as you will continue, it will open the public/private key pair generation window for you. Generate the key/value pair and download the same by clicking over the create and download key/value pair button.
  8. Allow downloading this key/pair file because this is highly important and helps you to launch your instances and connecting with other instances too.
  9. Once you have download it successfully, it will ask you for a security group to run the instances.
  10. This was the final step, Now review the settings or other things with which an instance is supposed to be launched. If you wanted to modify anything then click on backlink and make the changes by jumping to previous steps.

Congratulations! With these easy steps, you are ready to launch or manage your instance within minutes. You just need to follow all these steps one by one and you are done. Now you could connect to other instances and manage them properly as needed. To manage an instance, go to the dashboard again and see the list of already created instances there.
