Weekly DevOps Track #1 – 14/07/2018

Some great posts this week on important topics, including the economics of serverless, management in organisations adopting devops, and the importance and risks of metrics and measurements.


News

1 -) An excellent, detailed analysis of the economics of serverless – looking at when EC2 pricing is more efficient than AWS Lambda. Lots of data and the assumptions made.

2 -) A post on the human scalability of devops. Lots of good points, although the arguments are based on a specific definition and a startup usecase. In my experience large organisations are better about the non-fungibility of engineers.

3 -) Metrics and measurement are important parts of adopting devops but using the wrong metrics, or not evolving those metrics as your organisation evolves, can be problematic.

Continuous testing is an integral part of the DevOps process and critical to achieving continuous delivery. The benefits of continuous testing are numerous, from increasing speed to market to reducing overall costs. But it can be a tricky sell to decision-makers. In this webinar, we’ll provide a deeper look at continuous testing, including the benefits and potential pitfalls, and what organizations need to implement a successful continuous testing environment.
