From InfoWorld: Like many cloud services, IBM's Bluemix PaaS has nominally been a multitenanted system -- a boon for sharing resources, but not so great if you worry about performance or security issues. The newest version of Bluemix, though, aims to win over those who want their cloud to be their cloud.
The new offering, called Bluemix Dedicated, is built using "dedicated hardware from within a SoftLayer cloud center and direct network connectivity to the enterprise," as IBM states in its press release.
The big drawback is that it's initially designed to provide only a curated subset of Bluemix services, running on dedicated metal without the need for the user to manage said metal. The services include Cloudant's NoSQL product, based on Apache CouchDB; a set of runtimes for various languages (to be named later); data caching services; and the MQ Light messaging service. Other services will be added, but no details have been provided as to when or which.
None of this is to say that Bluemix Dedicated runs in a vacuum -- services from Bluemix's public catalog and from IBM's Watson machine learning services are also available. But the actual customer apps run in an isolated environment built on Softlayer's architecture, which IBM has pushed as another selling point (especially with Softlayer's data centers available in multiple geographic regions). Softlayer has existing bare-metal offerings, although it's unclear if Bluemix Dedicated builds directly on top of that or is an entirely new creation that uses many of the same concepts.
