What is AWS and AWS EC2 Instance

Amazon Web Services (AWS)

It is a cloud computing platform provided by Amazon. The AWS offers all three service models such as for instance Software as a Service (SaaS), Infrastructure as a Service (IAAS), and Platform as a Service (PaaS).

There are more services which comprise the Amazon Web Services including Amazon Elastic Compute Cloud (EC2) which provides virtual servers, Amazon Simple Storage Service (S3) which provides scalable storage for backups, analytics.

Benefits of using Amazon Web Services:

  1. AWS gives access to organizations to make use of programming models, database and operating system.
  2. It provides a price effective service in that you just buy everything you use.
  3. Applications could be deployed in multiple regions with just a couple of clicks.
  4. AWS provides hybrid abilities to work with.
  5. Data centers could be maintained and run with no trouble without spending money.
  6. Cloud could be accessed easily with limitless capacity.
  7. Amazon Web services host dynamic websites to perform web and application servers.
  8. Large amount of emails could be sent over using AWS.
  9. All files will be stored securely, which may be accessed from anywhere.


AWS EC2 Instance

Amazon Elastic Compute Cloud (Amazon EC2) provides scalable computing capability in the Amazon Web Services (AWS) cloud. Using Amazon EC2 eliminates your need to invest in hardware at the start, in order to develop and deploy applications faster. You should use Amazon EC2 to launch as many or as few virtual servers as you need, configure security and networking, and manage storage. Amazon EC2 lets you level up or down to contract with changes in requirements or spikes in popularity, reducing your need certainly to forecast traffic.

Features of Amazon EC2

  • Provides Virtual computing environments, called instances
  • They are preconfigured templates for the instances, called Amazon Machine Images (AMIs) that package the bits you need for the server
  • Various configurations of CPU, memory, storage, and networking convenience of your instances, called instance types
  • Secure login information for the instances using key pairs (AWS stores the public key, and you store the private type in a secure place)
  • Storage volumes for temporary data that’s deleted when you stop or terminate your instance, called instance store volumes
  • Persistent storage volumes for your data using Amazon Elastic Block Store (Amazon EBS), called Amazon EBS volumes
  • Multiple physical locations for the resources, such as for instance instances and Amazon EBS volumes, called regions and Availability Zones
  • A firewall that lets you specify the protocols, ports, and source IP ranges that will reach your instances using security groups
  • Static IPv4 addresses for dynamic cloud computing, called Elastic IP addresses
  • Metadata, called tags, as you are able to create and assign to your Amazon EC2 resources
  • Virtual networks you can create which are logically isolated from the rest of the AWS cloud, and as you are able to optionally connect to your personal network, called virtual private clouds (VPCs)
