DEVOPS WEEKLY ISSUE #230

DEVOPS WEEKLY ISSUE #230 - 31st May 2015

A bit of a monitoring/performance/security feel this week - mainly due to Velocity conference this last week and partly as I’m heading to Infosecurity Europe this coming week. Thanks to folks who sent me infrastructure testing links last week too.

A good discussion, backed by some data, on the security considerations of running third party containers downloaded from the internet. Worth reading both posts.

How are trends like software as a service, cloud computing, containers, etc. affecting traditional IT asset management practices in large organisations?

Security @Scale happened last year but I missed this post which features some excellent videos on securing chatops, running a bounty program and several examples of in-house security tools.

Someone recently asked me for a list of good books to read on information security. I wrote it up as a blog post which a few people might find interesting.

Ignoring the nagios-bashing this is a good post about using consul’s built-in health checking as the foundation of a monitoring system. Includes code samples for sending alerts to a third party alerting system.

An in-depth tutorial from Velocity digging into linux performance management tools.

Another talk from Velocity, this one about using your monitoring tools to build a performance alerting system, and making those alerts actionable.
