SOA concepts have been around for a while and all of the benefits and promises it offers look good on paper. The complexity of implementing and deploying SOA in large enterprises is, however, often overlooked. The problems get further exacerbated when trying to migrate from existing monolithic web applications and its infrastructure to an SOA model, rather than starting fresh from the ground up. In this presentation, after a brief recap of the SOA model and its benefits, some of the real challenges in moving to the SOA model, in a large enterprise are discussed. These challenges include technical as well as operational. The talk then covers how we are addressing some of these challenges in building the SOA platform at eBay, without getting into eBay specifics. The session concludes with some key take away points to keep in mind when considering a SOA model.

Service-oriented architectures (SOAs) have evolved over the past few years out of the original vision of loosely coupled web services replacing constrained, stovepiped applications throughout enterprise IT. Every major enterprise technology vendor today has developed its own SOA strategy, supported by innumerable mid-size companies and start-ups offering specific SOA aspects or entire solutions. This explosive growth in SOA technology is in response to a global demand--IDC estimates that spending on SOA services alone will grow from $8.6 billion to more than $33 billion by 2010.
