What can you learn about Dockerizing microservices?
Sumo Logic has a broad-scale initiative to Dockerize it's service and JFrog's Xray was built from the ground up using Docker. The Sumo Logic engineering team has learned a lot in going through this process of Dockerizing microservices. As Sumo Logic’s Chief Architect, Stefan Zier, explains, "Some of Sumo Logic's microservices have 1,000+ instances of the service running and when we do an upgrade we need to pull 1,000+ in a reasonable amount of time - especially when we’re going to do continuous deployment." In terms of adoption and learning curve.
Stefan suggests:
- Developer Education – Docker is a new and foreign thing and the benefits are not immediately obvious to people.
- Communication – Talking through why it’s important and why it’s going to help and how to use it.
- Workshops – Sumo Logic does hands-on workshops in-house to get its developers comfortable with using Docker.
- Culture – Build a culture around Docker.
- Plan for change – the tool chain is still evolving. You have to anticipate the evolution of the tools and plan for it.
JFrog’s Co-founder and Chief Architect, Fred Simon, then explains how Frog Dockerized their pure SaaS Bintray, which is a distribution hub for all the packages around the world, and how they built their latest product, Xray, from the ground up using Docker.
