Attended my first AWS re:invent conference. It was definitely a great experience. While the breakout sessions where okay, what I most enjoyed is the energy with 30k AWS enthusiasts in the building. And the re:play party was awesome – especially the performance by Martin Garrix.
Notes on getting Docker Swarm cluster running on two Raspberry Pi 3 devices. We will then deploy a simple nodejs app container on the new cluster.
Updated one of my previous Spring Boot sample service to run within a Docker container – https://github.com/thomasma/quote-service-docker. You can run it locally w/o Docker as a regular Spring Boot app and next run it inside a Docker container. Make sure that you have Docker setup correctly and tested prior to running this app.
It is hard not to be affected by the constant chatter on Microservices Architecture and Container technology. Both are leading the discussions nowadays and they combine to provide new ways to Architect distributed systems and provide agility in delivering business value. While they do bring in big benefits when implemented successfully, the path to success for most enterprises (other than startups/product/tech firms) is going to be difficult and having a level of measured caution would be good.
Random thoughts on mobile from a presentation slide I created a while back and some updates thoughts based on new information from talking to another expert.
To discuss Serverless Architecture we need to understand how we got here. From using physical machines we moved to virtual machines (somewhere in between a few brave folks also used linux/solaris containers). The current trend is container technologies such as Docker or CoreOS RKT which allow even more efficient use of resources. Regardless of which you use, we are often required to plan our application infrastructure needs upfront and permanently keep the “servers” running.
