In this age of rapid digitalization, everyone needs the access to computers, be it for technological purposes eating up a lot of computing power such as software development, big data analysis or video rendering to everyday requirements such as gathering information and releasing information. Businesses need the huge computing power to run their tasks of multiple kinds which keeps on increasing by the time.
In this scenario, it becomes hard to acquire the hardware when you need it which in turn hampers the business processes. Amazon Elastic Compute Cloud provides highly scalable computing capability within the Amazon internet Services (AWS) cloud. Working on Amazon EC2 eliminates your potential to invest in hardware up front, thus you’ll be able to get access to all the computing power within minutes.
It gives you the ability to resize the machines size and its configuration as per the optimal usage within minutes hence, saving you a great deal of cost in the process. Another beauty of cloud computing is that you have to pay for what you use and when you use it. For example, if you use a machine for 10 hours day, you only have to pay for those 10 hours subsequently, reaching to the optimal cost that your business should incur over the IT.
Functioning of EC2
Amazon EC2 presents a true virtual computing environment, allowing you to use web service interfaces to launch instances with a variety of operating systems.
To use Amazon EC2, you simply:
- EC2 gives you the ability to choose the location where you want your virtual instance to be which are called regions and availability zones. For example, a company in India would like to have their machine running in India, thereby, choosing Mumbai as their location to keep the instance
- Choose which instance type with required configurations to run your workload, then start, terminate, and monitor as many instances needed
- Pay only for the resources that you actually consume, like instance-hours or data transfer.
- Resize the instances as per your new and revised requirements.
AWS EC2 Storage
Amazon EC2 storage includes two types of storage which are:
- Amazon EBS
Amazon Elastic Block Store helps us with block-level storage which is compatible with the EC2 instance. Moreover, they are highly available and reliable and can attach to any working instance available in the same Zone.
- Instance Store
It is a block-device storage which comes in the form of directly attached with EC2 Instance. The instance store is ideal for temporary storage, because the data stored in instance store volumes is not persistent through instance stops, terminations, or hardware failures.
Features to increase the capability of EC2
- Elastic Load Balancing
AWS ELB automatically distribute incoming application traffic across multiple instances. You can add and remove compute resources from your load balancer as your needs change, without interrupting the overall flow of requests to your applications.
- Amazon Cloudwatch
You can use Amazon Cloudwatch to monitor basic statistics for your instances and Amazon EBS volumes. Amazon Cloud Watch Events informs a near real-time stream of system events that describe changes in Amazon Web Services resources. Activating Lambda function whenever a new AWS EC2 instance starts, done with the help of Cloudwatch in Amazon.
- Amazon Cloudtrail
Amazon Cloudtrail is a web service that records API activity in the AWS account. It provides surveillance to the calls made to the AWS EC2 API for the personal account. It can be uses for calls made by AWS Management Console, command line tools, and other services.
