			<content:encoded><![CDATA[<p>Well, not anytime soon. But for those of us working and thinking outside the parameters of conventional enterprise software, LAMP stacks and so forth, some alternatives are emerging. I am only beginning to take a look at these. In particular I am interested in high availability in <i>the cloud</i>. Now that comes with its own unique set of challenges, not least of all coming to grips with losing the &#8216;C&#8217; in ACID. <a href="http://www.25hoursaday.com/weblog/default.aspx">Dare Obasanjo</a> has captured this challenge in his post <a href="http://www.25hoursaday.com/weblog/2007/10/10/WhenDatabasesLieConsistencyVsAvailabilityInDistributedSystems.aspx">When Databases Lie</a>. More challenges and opportunities are documented by Charles Ying in <a href="http://">What You Need To Know About Amazon SimpleDB.</a></p>
<p>Way back in 1999 I tried to shed relational database by using quite a few good <a href="http://en.wikipedia.org/wiki/Object_database">object relational databases</a>. It was a liberating experience, and I grew and learned by making some bad mistakes, including making the data unsearchable. I think that is a lesson I can carry forward when looking at the new breed of high availability, on-demand scalable candidates. You do have to build your own indexes for text search.</p>
<p>Today we have more reason to look beyond relational databases. They just don&#8217;t work that well in <i>the cloud</i>.</p>
<p>At <a href="http://www.synthasite.com">SynthaSite</a>, we will be building prototypes around some of the candidates out there. These include <a href="http://www.erlang.org/doc/apps/mnesia/index.html">Mnesia</a>, <a href="http://www.amazon.com/b?ie=UTF8&amp;node=342335011">SimpleDB</a>, <a href="http://couchdb.org/CouchDB/CouchDBWeb.nsf/Home?OpenForm">CouchDB</a> as well as abstractions like <a href="http://elastra.com/">Elastra</a>. We will also be taking a long hard look at using data store alternatives if the requirements are simple enough. <a href="http://www.danga.com/mogilefs/">MogileFS</a> is a candidate in this regard.</p>
<p>I am working with a great team, which helps when grappling with these things. In particular I am enjoying working with <a href="http://nxsy.org/">Neil</a> for whom I have had great respect over the years, but until now I have not had the opportunity to work closely with.</p>
<p>Neil is also the one who gave me <a href="http://nxsy.org/blog/archives/2008/02/11/demystifying-clouds">shove</a> to start blogging again.</p>
