DEVOPS WEEKLY ISSUE #474 - 26th January 2020
Lots of build posts this week, on new build tools, developer framework integration and the security of build servers. Plus operations lessons, devops reading and the shift from infrastructure to application and product teams.
From our sponsor, VictorOps

News
A long list of lessons learned doing operations. Light-hearted, but an awful lot to nod along to. Worth reading in particular if you’re new to ops work.
