Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. Amazon EC2’s simple web service interface allows you to obtain and configure capacity with minimal friction. It provides you with complete control of your computing resources and lets you run on Amazon’s proven computing environment.
Amazon EC2 is the most used AWS service. It lets users create virtual machines of their own choice of configurations. Here in this blog, you will learn what is EC2 and how it works. Towards the end, there is also a beginner-friendly demo to help you get acquainted with Amazon EC2.
Amazon EC2 is without any doubt the most used AWS service that lets users launch and manage server instances, at any time and for as long as one needs. Here in this Amazon EC2 tutorial, we will learn what is EC2 in AWS and how it works. Towards the end of this Amazon EC2 tutorial, there is also a beginner-friendly demo to get you started with Amazon EC2.
EC2 also allows users to build apps to automate scaling according to changing needs and peak periods, and makes it simple to deploy virtual servers and manage storage, lessening the need to invest in hardware and helping streamline development processes.
EC2 setup involves creating an Amazon Machine Image (AMI), which includes an operating system, apps, and configurations. That AMI is loaded to the Amazon Simple Storage Service (S3), and it’s registered with EC2, at which point users can launch virtual machines as needed.
What is EC2 in AWS?
Amazon EC2 is one of the most used and most basic services in Amazon so it makes sense to start with EC2 when you are new to AWS. But the first question here is, what is EC2 in AWS?
Well, to be very simple, it is a machine with an operating system and hardware components of your choice. But the difference is that it is totally virtualized. You can run multiple virtual computers in a single physical hardware.
Elastic Compute Cloud (EC2) is one of the integral parts of the AWS ecosystem. EC2 enables on-demand, scalable computing capacity in the AWS cloud.
Amazon EC2 instances eliminate the up-front investment for hardware, and there is no need to maintain any rented hardware. It enables you to build and run applications faster. You can use EC2 in AWS to launch as many virtual servers as you need. Also, you can scale up or down when there is an increase or decrease in the website traffic.
The word ‘elastic’ in Elastic Compute Cloud talks about the system’s capability of adapting to varying workloads and provisioning or de-provisioning resources according to the demand.
Reason of selecting an Amazon EC2
- Auto-scaling
- Pay-as-you-go
- Increased Reliability
- Elasticity
Auto-scaling:
This is the benefit which makes most businesses opt for AWS EC2. It is already explained earlier how Netflix uses auto-scaling to its advantage and provides a crash-free experience.
Auto-scaling is basically providing resources according to the demand. They either scale up or scale down corresponding to the increase or decrease in demand.
Pay-as-you-go:
You will be charged by the hour, and you have to pay only for what you have used. A company, XYZ might be using 100 servers normally, and on Mondays it scales down to 50 servers. So, it only has to pay for 50 servers those days, not the usual fee for the usage of 100 servers.
Even when you use your Amazon EC2 instances services for a few hours, you only need to pay for that time period and nothing more.
Increased Reliability:
AWS is spread across 20 worldwide regions with 61 availability zones (AZs) which helps your business when it is expanding. Also, this will increase the load speed of your application around the world.
You can always store multiple copies of your application in multiple AZs so that when one data center fails or loses data, the application will not fail completely.
Elasticity:
Instead of 10 low-configuration machines, you could rent a single high-configuration machine with an OS of your preferred choice for your application. Elasticity is the feature from which Elastic Compute Cloud got its name.
Moving on in this what is EC2 in AWS tutorial, let’s now see different types of AWS EC2 Instance Types.
A number of benefits and features draw developers to EC2 for cloud computing. Chief among these are:
Responsiveness to changing capacity requirements: The easy scaling of EC2 eliminates development obstacles that occur when applications require more resources.
Flexibility in configurations: Users can choose memory size, CPU, and boot partition size optimized for the OS they choose.
- Integration: EC2 can integrate with other AWS services, such as RDS, SimpleDB, and SQS.
- Precise control: Users get administrative access to their instances, can stop and start instances while retaining boot partition data, and can access console output for the instance.
- Security: Users can control which instances remain private and which have internet exposure. EC2 leverages Amazon Virtual Private Cloud (VPC) for security, and businesses can connect their secure IT infrastructure to resources in VPC.
- Cost: Among a number of pricing options, EC2 offers affordable hourly rates.
