Bluemix Dedicated offers an isolated, single-tenant version of IBM's Bluemix SaaS, but only a subset of services
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 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.
Another
Bluemix addition that goes hand-in-hand with Dedicated is what IBM
called a Private API catalog, a collection of APIs that allow developers
to connect their existing on-premise systems with IBM's Bluemix. An
organization can in effect republish its data through Bluemix and make
it available as a service, either to other internal developers or
external third parties. A company that can't or doesn't want to move its
data into the cloud at all, even to an isolated instance like Bluemix
Dedicated, could use this as a halfway-house solution.
Aside from
the usual questions about how large an audience IBM can find for Bluemix
Dedicated, other competition may arise in terms of how -- or whether --
rival clouds can provide true single tenancy, either for VMs or for
application stacks. Google, Amazon, and Microsoft don't offer bare metal
as an option (yet). Rather, they're pinning their hopes on the idea
that application-level containers and other technologies can provide
performance as good as dedicated iron.
IBM's Bluemix PaaS has
evolved from simply another PaaS offering to becoming an arena in which
IBM is hoping to reinvent itself from the inside out. By moving its
disparate offerings under a single API-connected roof, IBM has clarified
both what it has to offer enterprises and how it can be used. This has
also given IBM a fresh way to stay current -- by integrating more closely with new technologies like Docker.
IBM's earlier talk of leveraging Softlayer's single-tenanted, highly granular systems
is now taking a specific form. Rather than resell existing Softlayer
offerings, IBM is using that infrastructure to build entirely new
products aimed at itches the rest of the cloud hasn't completely
scratched.
