I Banned E-Mail At My Company — Email should not be used to share information. Especially if that information is a resource that might be useful again in the future.
Building Microservices at Karma — The biggest challenge with microservices is testing. With a regular web application, an end-to-end test is easy: just click somewhere on the website, and see what changes in the database. But in our case, actions and eventual results are so far from another that it’s difficult to see exact cause and effect. A problem might bubble up from a chain, but where in the chain did it go wrong? It’s something we still haven’t solved.
Failing at Microservices — deconstructed a failed stab at microservices. Category three engineers also presented a significant problem to our implementation. In many cases, these engineers implemented services incorrectly; in one example, an engineer had literally wrapped and hosted one microservice within another because he didn’t understand how the services were supposed to communicate if they were in separate processes (or on separate machines). These engineers also had a tough time understanding how services should be tested, deployed, and monitored because they were so used to the traditional “throw the service over the fence”to an admin approach to deployment. This basically lead to huge amounts of churn and loss of productivity.
