mediaSaaS utilizes EC2, a web service from AWS that provides resizable computing capacity to build and host software platforms. A separate Virtual Private Cloud (VPC) is created for each customer, and the VPC includes three “Availability Zones” physically located in different data centres.
The production platform is located in 2 availability zones, with usage optimised via load balancing. In case of failure at one site all usage is balanced to the other platform
The third availability zone is used for monitoring software, providing 24×7 active monitoring.
