REA’s journey with Amazon Web Services (AWS) began in late 2010 when we started experimenting with using the cloud for our dev/test infrastructure. In 2013 we launched our first cloud-only production infrastructure to handle the dynamic resizing and serving of our images. Since that time we have adopted an IT strategy that involved transitioning all systems to the cloud and have therefore run a hybrid cloud and data centre platform ever since. More recently we have also embraced micro-services which means the volume of systems that we run in the cloud has exploded. This blog covers how our usage of AWS accounts and VPCs has changed and what we propose to do next.
