One of the first things I learned when I started talking with clients about their plans for platform-based clouds is that there is no such thing as a ‘simple application environment.’ Even for the most basic, CRUD-style applications, you can count on there being numerous different components involved in the overall solution. While one may immediately identify application servers, web servers, and databases, it quickly becomes clear that LDAP servers, identify management components, data grids, load balancers, and more are equally important. Indeed, the enterprise application ecosystem is not one where the word ‘simple’ is often tossed about.
The inherent complexity of enterprise application environments has had, and will continue to have a significant impact on the design and implementation of many PaaS solutions. In fact, one could argue that the preeminent design point in many PaaS solutions on the market today is rooted in eliminating this complexity. To do this, PaaS solutions attempt to abstract all the way up to the application level. In other words, users supply application artifacts and possibly define application characteristics. From there, it is the job of the PaaS system to handle the underlying application infrastructure, completely absolving the deployer from having to get into the nitty-gritty of the application serving environment…
