The converged infrastructure value proposition, by now, is pretty evident to everyone in the industry. Whether that proposition can be realized, is highly dependent on your particular organization, and specific use case.
Over the past several months, I have had an opportunity to be involved with a very high-profile pilot, with immovable, over-the-top deadlines. In addition, the security requirements were downright oppressive, and necessitated a completely isolated, separate environment. Multi-tenancy was not an option.
With all this in mind, a pre-built, converged infrastructure package became the obvious choice. Since the solution would be built upon a suite of IBM software, they pitched their new PureApplication system. My first reaction was to look at it as an obvious IBM competitor to the venerable vBlock. But I quickly dismissed that, as I learned more.
The PureApplication platform is quite a bit more than a vBlock competitor. It leverages IBM’s services expertise to provide a giant catalog of pre-configured multi-tiered applications that have been essentially captured, and turned into what IBM calls a “pattern”. The simplest way I can think of to describe a pattern is like the application blueprint that Aaron Sweemer was talking about a few months back. The pattern consists of all tiers of an application, which are deployed and configured simultaneously, and on-demand.
As an example, if one needs a message broker app, there’s a pattern for it. After it is deployed (usually within 20-30 mins.), what’s sitting there is a DataPower appliance, web services, message broker, and database. It’s all configured, and ready to run. Once you load up your specific BAR files, and configure the specifics of how inbound connections and messages will be handled, you can patternize all that with script packages, so that next time you deploy, you’re ready to process messages in 20 minutes. If you want to create your own patterns, there’s a pretty simple drag and drop interface for doing so.
I know what you’re thinking. . . There are plenty of other ways to capture images, vApps, etc. to make application deployment fast. But what PureApp brings to the table is the (and I hate using this phrase) best-practices from IBM’s years of consulting and building these solutions for thousands of customers. There’s no ground-up installation of each tier, with the tedious hours of configuration, and the cost associated with those hours. That’s what you are paying for when you buy PureApp.
Don’t have anyone in house with years of experience deploying SugarCRM, Business Intelligence, Message Broker, SAP, or BPM from the ground up? No problem. There are patterns for all of them. There are hundreds of patterns so far, and many more are in the pipeline from a growing list of global partners.
The PureApplication platform uses IBM blades, IBM switching, and IBM V7000 storage. The hypervisor is VMware, and they even run vCenter. Problem is, you can’t access vCenter, or install any add-on features. They’ve written their own algorithms for HA, and some of the other things that you’d expect vCenter to handle. The reasoning for this, ostensibly, is so they can support other hypervisors in the future.
For someone accustomed to running VMware and vCenter, it can be quite difficult to get your head around having NO access to the hosts, or vCenter to do any troubleshooting, monitoring, or configuration. But the IBM answer is, this is supposed to be a cloud in a box, and the underlying infrastructure is irrelevant. Still, going from a provider mentality, to an infrastructure consumer one, is a difficult transition, and one that I am still struggling with personally.
The way licensing is handled on this system is, you can use all the licenses for Message Broker, DB2, Red Hat, and the other IBM software pieces that you can possibly consume with the box. It’s a smart way to implement licensing. You’re never going to be able to run more licenses than you “pay for” with the finite resources included with each system. It’s extremely convenient for the end user, as there is no need to keep up with licensing for the patternized software.
Access to the PureApp platform is via the PureApp console, or CLI. It’s a good interface, but it’s also definitely a 1.x interface. There is very extensive scripting support for adding to patterns, and individual virtual machines. There are also multi-tenancy capabilities by creating multiple “cloud groups” to carve up resources. There are things that need to be improved, like refresh, and access to more in-depth monitoring of the system. Having said that, even in the past six months, the improvements made have been quite significant. IBM is obviously throwing incredible amounts of resources at this platform. Deploying patterns is quite easy, and there is an IBM Image Capture pattern that will hook into existing ESXi hosts to pull off VM’s to use in Pure, and prepare them for patternization.
Having used the platform for a while now, I like it more every day. A couple weeks ago, we were able to press a single button, and upgrade firmware on the switches, blades, ESXi, and the v7000 storage with no input from us. My biggest complaint so far is that I have no access to vCenter to install things like vShield, backup software, monitoring software, etc.. But again, it’s just getting used to a new paradigm that’s hard for me. IBM does have a monitoring pattern that deploys Tivoli, which helps with monitoring, but it’s one more thing to learn and administer. That said, I do understand why they don’t want people looking into the guts on a true PaaS.
Overall, I can say that I am impressed with the amount of work that has gone into building the PureApplication platform, and am looking forward to the features they have in the pipeline. The support has been great so far as well, but I do hope the support organization can keep up with the exponential sales growth. I have a feeling there will be plenty more growth in 2014.
