Amazon Web Services
The AWS Cloud is a cloud services platform developed by the American giant Amazon. AWS brings together more than 100 services divided into various categories such as cloud storage, computing power, data analytics, artificial intelligence or even video game development.
The AWS technology is implemented at server farms throughout the world, and maintained by the Amazon subsidiary.
Fees are based on a combination of usage (known as a “Pay-as-you-go” model), hardware, operating system, software, or networking features chosen by the subscriber required availability, redundancy, security, and service options. Subscribers can pay for a single virtual AWS computer, a dedicated physical computer, or clusters of either.
As part of the subscription agreement, Amazon provides security for subscribers’ systems.
AWS operates from many global geographical regions including 6 in North America.
Amazon markets AWS to subscribers as a way of obtaining large scale computing capacity more quickly and cheaply than building an actual physical server farm.
All services are billed based on usage, but each service measures usage in varying ways. As of 2017, AWS owns 33% of all cloud (IaaS, PaaS) while the next two competitors Microsoft Azure and Google Cloud have 18%, and 9% respectively, according to Synergy Group.
AWS provides services to customers when required without any prior commitment or upfront investment. Pay-As-You-Go enables the customers to procure services from AWS.

Through AWS, autoscaling and elastic load balancing techniques are automatically scaled up or down, when demand increases or decreases respectively. AWS techniques are ideal for handling unpredictable or very high loads. Due to this reason, organizations enjoy the benefits of reduced cost and increased user satisfaction.
