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.
