Nerval's Lobster writes: Developer and editor Jeff Cogswell asks: When it comes to implementing a CouchDB installation, do you roll your own, or go with a service that provides a hosted version of the database? He takes a look at some of the technologies present in CouchDB that can greatly influence that decision. His conclusion? Like all things, it's a little complicated. "If you’re going to be self-hosting—unless you’re working on a really small system—don’t use the basic CouchDB for anything," he writes. "If you want scalability, either go with Couchbase or BigCouch, or wait until Cloudant’s BigCouch merger into CouchDB is officially available." But going with a host also creates its own things to watch for, including potential issues with replication and eventual consistency.
