I was fortunate enough to attend QCon London 2015 last week, and so I present my 60 second review.
1. THE WHOLE WORLD HAS GONE MICROSERVICE MAD!
I guess this speaks to the success people are having with microservices, but MS-talk was all over this QCon. In fact, too much so. There was a lot of duplicate knowledge presented in talks, and by the end of it I was a little tired of it all.
2. New meme: Binary protocols, and protocol design.
With the explosion of microservices in-house, focus naturally comes to performance issues around TCP/HTTP/JSON etc. Many folks are dropping down to lower level, sometimes custom-written, protocols, eg. tchannel on Thrift at Uber.
3. Oh Node Where Art Thou?
For all it’s popularity, Node.js was pretty absent and if mentioned, only in dispatches, I would’ve liked to see more node-love.
4. Potential new meme: Actor-model. Some people seem to be attacking concurrency using the Actor model or “actor-based concurrency” (eg. Halo4 built on Azure using Orleans). I will be reading up more on this!
Overall, I was glad I was there, but I don’t think the talk curatorship was as good as previous years, and I would hesitate if using my own money to buy conference ticket! (I helped out as crew, which I have done for several years, and so get a free pass).
I will though of course be back next year!
Videos of talks will be released over time here:
