WHAT
IS
DEVOPS?
2013 GoodData Corporation. All rights reserved.

DevOps in a SaaS Company
▶ Beware: The code you write can wake you up in the
middle of the night! (Literally speaking.)

DevOps in a SaaS Company
▶ What is DevOps?
○ integrated cross-functional teams
○ Development + QA + Operations
▶ OK, so What do DevOps do?
○ It is not only about developing software, it is also about
running it on behalf of your customers:
■ monitoring, error reporting & alerting
■ ongoing performance optimizations & fine tuning
■ incremental feature rollouts (risk mitigation)
▶ All the above influences the way we architect and
develop our software and technologies we use.
