Explain some features of Amazon EC2?

Amazon EC2 provides the following features:
  • Virtual computing environments, known as instances
  • Preconfigured templates for your instances, known as Amazon Machine Images (AMIs), that package the bits you need for your server (including the operating system and additional software)
  • Various configurations of CPU, memory, storage, and networking capacity for your instances, known as instance types
  • Secure login information for your instances using key pairs (AWS stores the public key, and you store the private key in a secure place)
  • Storage volumes for temporary data that's deleted when you stop or terminate your instance, known as instance store volumes
  • Persistent storage volumes for your data using Amazon Elastic Block Store (Amazon EBS), known as Amazon EBS volumes
  • Multiple physical locations for your resources, such as instances and Amazon EBS volumes, known as regions and Availability Zones
  • A firewall that enables you to specify the protocols, ports, and source IP ranges that can reach your instances using security groups
  • Static IP addresses for dynamic cloud computing, known as Elastic IP addresses
