Happy SOA New Year!
Happy SOA New Year!!! Another fun SOA case study ! What is SOA? The most common analogy used to describe SOA is that of building blocks. Imagine standing side-by-side a toy car, and one built using Lego® blocks. The toy car represents a traditional IT application, and the one built of blocks represents an assembled application using SOA services. Both have the same basic function, but the car built of blocks can be easily modified – or even re-assembled into something completely different such as a toy airplane. An SOA Example: HousingMaps.com A good example of a composite SOA-driven application is HousingMaps.com. This consumer facing web application takes information from Craigslist about houses for rent or for sale and merges it with location data from Google Maps. The result for users is a location-based view of all the properties for rent or sale within a specific geography. Users can click on any spot in the map to see the detailed property listing from Craigslist. The application works because both Craigslist and Google chose to expose portions of their applications as services using standard protocols. If their respective applications were completely self-contained in the model of traditional IT applications, then the only way to achieve HousingMaps functionality would be to write an entirely new application from scratch!
