Hello Folks,
Thanks for popping by, I’m Tariq Khurshid and lead on the website (www.tfl.gov.uk), Service Desk, Change & Release Management. In this blog I’d like to share with you the success we have enjoyed using the “blue/green” approach for software release and deployment in the new website.
This is a summary of our experience doing blue/green software deployments and releases to tfl.gov.uk using Amazon Web Services (AWS) cloud infrastructure.
Blue/green deployment of software to the website is a process that we use to safely release new versions of (www.tfl.gov.uk) without any down time or outages for customers.
The key to success is to maintain two identical production environments to switch between. As (www.tfl.gov.uk) is now hosted on virtual servers in the cloud, this is relatively easy and cost effective.
Blue/green deployment allows us to develop software to a high standard, test independently of the live site and easily package and then deploy to live. This means we have the ability to rapidly, reliably and repeatedly push out enhancements and bug fixes to (www.tfl.gov.uk) at low risk, with minimal overheads, and best of all,….. no outages for customers.
