I’m out in San Francisco this week for PuppetConf, if anyone happens to be around do let me know. Because of all the travel this was going to be a short issue but I found too much good content.

A great post on the importance of management, in particular picking up the over-emphasis on technical skills in technical environments at the expense of understanding the importance of management.

A good exposition of things you need in place to take advantage of a microservices style architecture. Lots of focus on operations here, including provisioning, monitoring, deployment and product centric teams.

A useful post on the concept of technical debt, applied to infrastructure and operations. Lots of good observations about how to spot debt and what to do about it.

Last week was Velocity New York, from which a view of the posts this week are taken from. Lots of the keynote videos are already up too, with talks on team organisation to monitoring and data storage to low level network optimisation.

A nice detailed look at the HTTP Vary header. Explains why Vary is so powerful and how to avoid common configuration problems.

A nice short post on application architecture, a reminder that it’s as much an organisation design problem as about software, and that different size teams might need to make different trade-offs.
