Docker images for developers

Docker seems to be all the rage lately. There are docker talks at every conference, hosting Docker containers has become a hosting option with most if not all PaaS providers, and there is hardly a technology left that is not supposed to run better and more flexibly if you wrap it in a Docker container. Well, except maybe for enterprise-level DBMSs, but you can’t have them all. This post provides an example how Docker can be used at the start of the software lifecycle, during development.

Scalable Software Systems

Scalability has long been one of the hallmarks of quality IT systems. When we hear this term we usually associate it with an upward scalability of the system. Generally, it seems to be about how much more throughput and load our system can sustain through additonal RAM, CPU or extra machines. Often, however, downwards scalability is just as interesting, that is, the behaviour of the system when only very few resources are available. Such flexibility is very useful, for instance, if a complex system has to go through a variety of differently sized development, test and acceptance environments before it is provisioned in the live system.
