Devopsgirls 2.0

Only 6 months has passed since our inaugural DevOps Girls bootcamp and on Saturday 12th of August 2017 we had the pleasure of running the second edition. For those new to the bootcamp: it is a free event for women interested in learning more about devops, run by a community of passionate volunteers.

The idea started with a realisation that unless we are proactive about diversity in tech and we make meaningful contributions, it’s going to be hard to move the needle on this.

Essentially the system transforms a very large dataset into smaller ones that are used to create audiences or data segments which are used for hyper targeted EDMs.

To get from the initial state to the final state, the data is transformed over several stages using 8 Lambdas. Continue reading

Static assets in an eventually consistent webapp deployment

The Problem

Deploying a high traffic website with zero downtime is a challenge – there’s a natural tradeoff between:

  • Performance and cacheability.
  • Getting updates versions of the application live.

The approach you use to manage your static assets plays a big role in this.

This post explains how we dealt with the challenges in our move from the data centre to a multi region highly available cloud-based architecture.
