Amazon Web Services  or AWS in short,  is a bundled remote computing service that provides cloud computing infrastructure over the Internet with storage, bandwidth and customized support for application programming interfaces (API).

Amazon Web Services or AWS,  provides

  • cloud computing infrastructure over the Internet with
    • storage
    • bandwidth
    • customized support for application programming interfaces (API).

AWS facts

  • Was launched in 2006 by Amazon, Inc, USA,
  • Before launch, it was Amazon’s internal IT team efforts to build resource management.
  • AWS uses the subscription pricing model of pay-as-you-go or pay-for-what-you-use.
  • Amazon packages AWS with scalable and virtually unlimited computing, storage and bandwidth resources.
  • AWS offers various cloud computing options like infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS) offerings.

How AWS Delivers – Server virtualization

Server virtualization technique –

  • partitions a physical server into a number of small, virtual servers with the help of virtualization software.
  • Each virtual server runs its own operating system and software
  • Multiple such virtual server can run on single physical server at the same time.
  • Adding a new virtual server is quick, compared to purchase / configuring a physical server.
  • Virtual server can utilize 100% of hardware.

Compute Services

  1. EC2 or Elastic Compute Cloud – It is a virtual machine in the cloud on which user has OS level control. You can run this cloud server whenever you want.
  2. AWS Lambda — ThisAWS service allows you to run functions in the cloud.

Storage Services

  1. Amazon Glacier- It is an extremely low-cost storage service. It offers secure and fast storage for data archiving and backup.
  2. Amazon Elastic Block Store (EBS)- It provides block-level storage to use with Amazon EC2 instances. Amazon Elastic Block Store volumes are network-attached and remain independent from the life of an instance.
  3. Amazon S3 – With this component one can retrieve the input data sets which are involved in creating cloud architecture and output data sets also can be stored in this component that is the result of the input given.
  4. Cloud Front – It is a web service; with this you can fastness in distributing the inert and active web content. For example, .html, .php files to clients

Management Services

  1. CloudWatch — Cloud watch helps you to monitor AWS environments like EC2, RDS instances, and CPU utilization. It also triggers alarms depends on various metrics.
  2. CloudFormation — It is a way of turning infrastructure into the cloud. You can use templates for providing a whole production environment in minutes.
  3. OpsWorks — The service allows you to automated Chef/Puppet deployments on AWS environment.

AWS Cloud Features

  • Available – Multiple redundancy to address one component failure. Workload is shifted to a operational replacement. Thus, connect resources in geographically isolated locations and also address failures for a complete region during disaster.
  • Scalable –Computing resources as per user’s need, on-demand. Offering should be too low as against costs involved in client running workload on own.
  • High levels of security – maintain high standards in IT security. Taking responsibility for AWS networking and compute infrastructure security and, relieving customer of these tasks.  Applying AWS Shared Responsibility Model which outlines AWS being responsible for the cloud infrastructure only and customer for rest.
  • Metering mode– AWS is a self-service system to be used by anyone and with payment only for resource usage. Automated billing as per the usage.
