Jihai Zhou is going to tell us about implementing DevSecOps in large banks. #DevOpsDays In Jihai’s experience in London, a strong concept of DevOps has developed over the last 3-4 years. He just moved to HSBC’s Technology China office and finds the awareness of DevOps is less developed there (so far!). #DevOpsDays

Arun Kumar Singh is now talking about a journey to self-healing infrastructure. #DevOpsDays He’s an SRE at Adobe, where each product has ~30k servers. If each server alerts once per week, that’s 30k alerts a week for the poor SRE! 😱 What to do? Auto-remediation (self healing) is a workflow triggered by an alert or event, which fixes the problem. Simplest example: the server is off, turn it on again. #DevOpsDays Slide: general auto-remediation workflow

.@roidelapluie is talking about Monitoring as an entry point for collaboration. Here’s the CAMS principles of DevOps: we’re going to talk about all of them. #DevOpsDays Culture, Automation, Measurement, Sharing Okay, you have your dashboard with green and red lights. And green, red, yellow, red, green? What does that all mean? It doesn’t tell us much about what’s really going on. Maybe the light is green but there’s a traffic jam... In-between states of working/not-working in the real world

Twitter was based on the idea of getting your friends together for a pizza or beer, and it ended up a platform for bad political ideas and harassing people.—@aspleenic #DevOpsDays I got here a bit late today and just arrived in @aspleenic’s talk on reactive programming. A good point to jump in. :) #DevOpsDays

Now @siruslan is going to talk about automatic scaling of the Java heap in the Elastic JVM. #DevopsDays We hear a lot about horizontal scaling, but people underestimate the use of vertical scaling. Java can be greedy... so much memory consumption! Before founding Jelastic, @siruslan found there was no good hosting for Java apps (vs. lots for PHP) because of that. #DevOpsDays

The next #DevopsDays Geneva speaker is @nat_remez: Fail fast, Fail often - make safety a prerequisite for your team devopsdays.org/events/2019-ge… When I skimmed over the title originally, I assumed this was about safety as in security, but actually it’s psychological safety—much more interesting, I think!

.@gsaslis and @mikz say that any project needs CI, but OSS projects need it more!
#DevopsDays Slide: any project needs CI, but OSS ones need it more! I think @DRMacIver and @alexwlchan would probably agree with this. #hypothesis #isThereAnOfficialHypothesisHashtagYet
