Journey Planner – Points of Interest

This is the first in a series of posts covering new or existing functionalities of Journey Planner, with the intention being that users (including developers subscribing to the API) can get the best from the system. In this post I’ll be looking at Points of Interest (POIs) and how we aim to make this information as comprehensive as possible, as well as asking for your suggestions for any new POIs you feel should be added to the system.

We believe that the Journey Planner should not just be accurate, but tailored to the needs of people who use it. To support this we actively manage a detailed database of Points of Interest within Journey Planner, covering places people are likely to travel by public transport, or cycle to. This is a combination of a bulk upload, and points we have added ourselves.

Blue/Green deployment strategy in the new TfL website

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.
