RavenDB in the Cloud

by Matthew Adams

We’ve been building some content-managed websites recently (this one, for instance). We needed a storage solution, and, as with many other document-centric applications, a document-orientated database is really what we want – something that lets us read, write and query document-structured data (1). With Microsoft Windows Azure you have a bunch of different storage options available. Key/Value Pair data […]
