Amazon Web Services Inc., is a subsidiary of Amazon aimed at providing on-demand cloud computing platforms and APIs to individuals, companies and governments on a pay-as-you-go basis. These services offered by Amazon provide distributed computing processing capacity and software tools through AWS server farms(An AWS server farm is a collection of AWS servers maintained by Amazon to supply server functionality far beyond the capability of a single machine). Amazon Elastic Compute Cloud(EC2), one of the most popular of these services, allows users to have a virtual group of computers available at their disposal through the Internet. These virtual computers are a simulation of most attributes of a real computer, like hardware CPUs and GPUs for processing; local and RAM memory; hard disk and SSD storage; a set of operating systems, networking and pre-loaded application software like web servers, databases and customer relationship management. AWS subscribers can pay for a single virtual AWS computer, a dedicated physical computer, or clusters of both.
Subscribers pay for hardware, OS, software or networking features as desired, regarding availability, redundancy, security and service options.
Amazon offers its services to its clients at a large scale computing capacity, and at a very affordable price. For this reason, AWS got 33% market share for cloud infrastructure as of 2021. These services comprise over 200 products, including storage, database, networking, analytics, application services, deployment, management, machine learning, mobile, developer tools, RobOps and IOT.
