Monolith to Microservices - Challenges and Lessons

location_city Sydney schedule Nov 28th 11:00 - 11:30 AM place Grand Ball Room 1
A microservices based architecture, while making many things better, brings its own set of challenges. In this talk, I will focus on the challenges we have faced and lessons learned at Expedia on 4 key topics. They are Scaling & Performance, Stability & Reliability, Monitoring & Performance, and Organisation.
In this talk, I discuss challenges faced at Expedia and lessons that we have learned through the process. The main themes covered are around org structure and design, stability & reliability, monitoring & observability, scaling & performance of microservices. I will help answer questions like
  • What should you think about, with respect to the org design before you break a piece of functionality from the monolith into its own service?
  • Why is a deployment pipeline a must have for any and every service?
  • What tasks should be automated?
  • Is there such a thing as too much automation?
  • What types of testing are needed in a microservices architecture?
  • What about monitoring and scaling? Why is this harder with a microservices architecture when compared with a monolithic architecture?
I recently presented this talk at YOW! Nights in Sydney and Brisbane.
