Microsoft Open Technologies is pleased to share the latest update to the Windows Azure self-deployment option for Apache Solr 4.0.
Solr 4.0 is the first release to use the shared 4.x branch for Lucene & Solr and includes support for SolrCloud functionality. SolrCloud allows you to scale a single index via replication over multiple Solr instances running multiple SolrCores for massive scaling and redundancy.
