Lean, mean Java web development - 2015 style

Because Java web servers are about as old as the web itself, and there are long, successful, traditions and practices associated with them – traditions which we will soon commence on dismantling – this is perhaps as good a time as any to explain what I mean by “modern” in this series’s title. In this context, I take “modern” to mean “in accordance with current general software development trends”. These trends aren’t completely arbitrary, and they are consistent with one another. The birth of a very large number of small, young, fast-moving startups, has given rise to a preference of lean development approaches. Those require easier onboarding, fewer installation, deployment and configuration steps, and a convergence of the roles of development and operations. The growing popularity of the cloud encourages certain approaches towards resource management, namely virtualization, either at the hypervisor level or the OS level. OS-level deployment/resource allocation also supports the proliferation of polyglot architectures, which seek to use the right (but possibly different) tool for each job.
