AWS bits and pieces – my journey to Certification

What is AWS?

Amazon Web Services or AWS is the worlds leading provider of IaaS public cloud.  it is also  not a single thing, it is made up of many different services, and is accessible from several locations across the world these locations are called Regions..

Currently AWS has 18 Regions these are shown below. It is important to remember that not all AWS services are available in every Region.

  • These regions are only available in China and only be accessed by Republic of China companies and citizens.

A Region is broken down in to a number of Availability Zones. The number of availability zones varies from region to region, ie there are more availability zones on more mature regions.

Availability Zones are identified by the appending of a alpha character to the end of a zone name for example ap-southeast-2a. which related to an availability zone in the Sydney Region.

It is also important to know that availability groups are not immutable, what is your availability zone “a” is not necessarily the same zone for another customer. Also there is now way to coordinate Availability Zones between accounts.

That is a high level overview of the AWS infrastructure,

In my next post we will start looking into the numerous services and functions that are available across the AWS suite. It is should also be noted that AWS are constantly introducing new and enhancing their current services and functions. Also these services and functions are also being rolled out to new regions from their initial launch region.
