AWS (Amazon Web Services) is a cloud IaaS platform that offers compute power, data storage, and a wide range of other IT services for the organizations. It is the most popular cloud hosting platform with over a million active clients from all over the globe.
 
With the AWS cloud infrastructure, organizations can enjoy lower management overheads, simple and flexible implementation with significant reductions in costs contrary to the legacy infrastructure solutions. Several organizations are discarding on-premise data centers in favor of the hosted AWS cloud solutions.

AWS infrastructure runs around AWS Regions and AWS Availability Zones. The AWS Cloud Infrastructure spans around 55 Availability Zones consisting of one or more distinct data centers within 18 geographical regions and 1 Local region globally. They are expanding with 12 more availability Zones and 4 Regions soon. Each of the Availability Zones has redundancy in power, networking connectivity, and other fault tolerant infrastructure assuring of high availability and scalability.

The AWS services were first initiated in 2006 with the Elastic Compute Cloud(EC2). This enables the clients to lease virtual systems managed by AWS and allows the customers to run their own applications. AWS was among the first organizations to adopt the pay-as-you-use cloud computing billing model and offer scalable storage and compute.
 
The EC2 offers virtual servers that they term as “Instances” in varying capacities that can be specifically designed to meet the demands of workloads and applications. The EC2 container services allow the clients to access Docket Containers on the AWS platform. Developers can avail the AWS Lambda for serverless functions and codes for services like AWS Batch and AWS Elastic Beanstalk.

AWS Simple Storage Services (AWS S3) delivers scalable storage for data backup, data archiving, and analytics. It offers the storage transport devices – AWS Snowball and Snowmobile to carry the on-premise data to the AWS cloud S3.

AWS Virtual Private Cloud (VPC) allows the client complete administrative control over their virtual network giving access to a private and isolated section of the AWS Cloud. The AWS Config. and AWS Trusted Advisor are built to guide the IT experts in configurations and avoid unnecessary expenditure that occurs on wrong deployments. AWS also offers Identity and Access Management(IAM) that enable the server admins to manage user access to services.
 
AWS Mobile Hub provides a suite of tools for the mobile app developers to deliver simple codes and samples. There are in total more than 100 such services that form part of the AWS Cloud infrastructure services.
