Couchbase Server 4.0 not only supports homogenous scaling in one dimension but it now supports heterogeneous scaling in multiple dimensions. Data, querying, and indexing services can now be deployed into "zones" within the cluster. The new Multi-Dimensional Scaling capability enables enterprises to optimize their database infrastructure with unparalleled precision. The enterprise benefits of Multi-Dimensional Scaling include: increased application performance and stability, increased operational efficiency and agility, and reduced hardware costs. In this talk, we will also review the new services available in Couchbase Server 4.0 that allows independent scaling of query, indexing and core data workloads, reducing interference and maximizing throughput.
