## Amazon Web Services
|
|||
|
|
|
|||
|
|
Amazon Web Services, or AWS for short, is a subsidiary of Amazon.com that provides on-demand cloud computing platforms to individuals, companies and governments on a
|
|||
|
|
paid subscription basis with a free-tier option available for 12 months. It along with Microsoft's Azure and Google's Cloud Platform are considered the three major
|
|||
|
|
public cloud vendors.
|
|||
|
|
|
|||
|
|
The technology allows subscribers to have at their disposal a full-fledged virtual cluster of computers, available all the time, through the internet. AWS's version of
|
|||
|
|
virtual computers have most of the attributes of a real computer including hardware (CPU(s) & GPU(s) for processing, local/RAM memory, hard-disk/SSD storage); a choice
|
|||
|
|
of operating systems; networking; and pre-loaded application software such as web servers, databases, CRM, etc. Each AWS system also virtualizes its console I/O (keyboard,
|
|||
|
|
display, and mouse), allowing AWS subscribers to connect to their AWS system from anywhere in the world using a modern browser. The browser acts as a window into the
|
|||
|
|
virtual computer, letting subscribers log-in, configure and use their virtual systems just as they would a real physical computer.
|
|||
|
|
|
|||
|
|
Subscribers can choose to deploy their AWS systems to provide internet-based services for their own and their customers' benefit. Since individuals or organizations
|
|||
|
|
using AWS do not physically own the AWS infrastructure, they do not have to deal with some of the maintenance tasks associated with owning a physical datacenter such as
|
|||
|
|
operating networking equipment.
|
|||
|
|
|
|||
|
|
AWS in particular has also been expanding on their cloud offerings. They are providing innovative services such as AWS Lambda, in which users only need to focus on
|
|||
|
|
writing code and not on the servers that will be running their code (giving rise to the new *serverless* movement). As a result of these benefits, cloud computing
|
|||
|
|
platforms such as AWS have been popular among startups who might initially have less capital to invest into their Information Technology or IT. Instead, they can focus
|
|||
|
|
on building great products for their users and growing their business over time with AWS’s on demand model.
|
|||
|
|

|||
