Twitter Heron is an alternative to Apache Storm with compatible API as it was developed from Apache Storm. The major difference I found was that Heron opts to get rid of Threads and going with Process based workers. This is surprising and I am not sure the any advantage it would have over Threads+Process. Heron also has done […]

Finally I signed up for Google Cloud free trial. I wanted to setup GamingIO.com game servers in a way that I could manage it better. I found AWS EC2 was not up to the task and to get even a usable performance for a single game instance I would need to shell out 25$ a […]
