What is Elastic Cloud

Functions of EC2

  • It provides you with complete control of your computing resources and lets you run on Amazon’s proven computing environment. 
  • Amazon EC2 reduces the time required to obtain and boot new server instances to minutes, allowing you to quickly scale capacity, both up and down, as your computing requirements change. 
  • Amazon EC2 changes the economics of computing. That means, pay for the usage you did.
  • Amazon EC2 provides developers the tools to build failure resilient applications and isolate themselves from common failure scenarios.

Key Points for Interviews

Learn these basic points on EC2 for your next interview.
  • EC2 is the basic fundamental block in AWS.
  • EC2 provides remote operations of virtual machines (VM) on Amazon’s infrastructure.
  • A single VM you can call an instance. Multiple instance types present in EC2.
  • A micro instance is the only EC2 instance type that is free and is also the most underpowered instance (613MB memory). 
  • The EC2 micro instance type is the least reliably provisioned; when demand on Amazon’s infrastructure is high, the micro instance gets the lowest priority.
