Hi Romain, tell us who you are and what lead you into microservices?<\/h3>\n

I\u2019m a young software developer, I\u2019ve co-developed the first version of Gatling, and worked as a consultant for several years. Afterwards, I have worked for around 5 years in a small team responsible for a large product, as developer, architect, and lead dev.<\/p>\n

We came to microservices not because of the hype, but, as we were two person responsible for everything (from source to production), we needed a way to simplify our work. Having small deployable units with a clearly bounded and defined context helps a lot in this case I think. This is actually just a matter of defining interfaces, abstractions and understanding the domain correctly.<\/p>\n

The process of \u201cgoing full microservices\u201d took us about 3 years from the first day we started to split our application, until the day I left the team to go help on another product in another company. This was a long time during which we learned a lot, and we never suffered from using microservices on the infrastructure side!<\/p>\n

What will you be talking about at Voxxed Days Microservices?<\/h3>\n

I will present a tools in action session about Habitat, the latest open source product from Chef. As said above, I think that what matters most when creating successful and maintainable software is finding the right abstraction for everything. Habitat helps around automating your application. It creates a boundary between the application and the infrastructure that is really powerful.<\/p>\n

On one side, developers use a simple shell script to define and build a package for their application, with the dependencies needed at build time and runtime, its configuration parameters and eventually configuration dependencies (think service discovery).<\/p>\n

On the other side, operations benefit from a unique package type that can be exported to whatever infrastructure they want: docker, kubernetes, mesos, bare metal, etc. Also, the configuration management for Habitat services is the same for every application, as the packages embed a supervisor for the application that can manage the service, from configuration changes to updates.<\/p>\n

Habitat helps a lot if you want to transition over to cloud native technologies, even with your old legacy software that can be packaged with habitat too!<\/p>\n

Docker, Kubernetes, Habitat\u2026 lately it seems that most of the innovation is made on the Ops side. Are developers becoming legacy and Ops being trendy ?<\/h3>\n

I think not. Actually, Ops look sexier now, sure. DevOps offers a nice range of declarative tools to manage infrastructure that become more complex as time goes. It also makes production infrastructure able to move and follow companies need for innovation.<\/p>\n

Most of these tools are also here to solve an organizational problem in most companies that have made developers and operations hate each other for a long long time. They bring power to both Devs and Ops so they can actually concentrate on what they do best. And this, I think is what I prefer in DevOps.<\/p>\n

Good, see you soon then<\/h3>\n

Thank you for the opportunity to show Habitat to VoxxedDays Microservices attendees, see you there!<\/p>\n
