  1. POPractical SOA for a newbie
    text
    copied!<p>I am a total newbie to the world of SOA. As such, I am looking at some "SOA frameworks/technologies", and trying to understand how to utilize them to build a highly scalable (Facebook class) website.</p> <p>There are several "pains" I am trying to solve here:</p> <ol> <li>Composability (+ managing dependencies, Pub/Sub)</li> <li>Language-independence of services</li> <li>Scalability &amp; Performance</li> <li>High availability</li> </ol> <p>I looked into some technologies that answer a subset of the above criteria:</p> <ol> <li><a href="http://incubator.apache.org/thrift/" rel="nofollow noreferrer">Thrift</a> - Facebook's cross-platform RPC platform</li> <li><a href="http://en.wikipedia.org/wiki/Windows_Communication_Foundation" rel="nofollow noreferrer">WCF</a> - supports SOAP, JSON &amp; REST, so it can be considered language-interoperable. Generates <a href="http://en.wikipedia.org/wiki/Web_Services_Description_Language" rel="nofollow noreferrer">WSDL</a> files that can be use to generate java proxies.</li> <li><a href="http://social.msdn.microsoft.com/Forums/en-US/roboticsdss/thread/babf3e90-8196-40b2-a4a1-5f2ecc4e9b47" rel="nofollow noreferrer">Microsoft DSS</a> - just inclued it in my survey, but it doesn't seem relevant as it is highly state-driven and .NET specific.</li> <li>Web Services</li> </ol> <p>Now, I understand how I get some aspects of composability and language-independence out of the above. But, I haven't found much concrete information (not buzz) about how to use the above / other tools for scalability and high availability. So finally I get to my question:</p> <p><strong>How does one leverage SOA technologies to solve the pains I defined above?</strong> Where can I find technical guides for that? I am looking for more than just system diagrams, but rather actual libraries, code samples, APIS...</p>
