Industry Commentary If I Were in IT Management Today...
Where I'd spend my management time

I’ve had a couple of blog posts talking about how there is a disconnect between “the market” and “the majority of customers” where things like cloud (and less so storage) are concerned. So I thought I’d try this out as a follow on. If I were running your average medium to large IT shop (not talking extremely huge, just medium to large), what would I be focused on right now.
By way of understanding, this list is the stuff I would be spending research or education time on, and is kept limited because the bulk of you and your staff’s time is of course spent achieving or fixing for the company, not researching. Though most IT shops I know of have room for the amount of research I’m talking about below. VIRTUALIZATION – management
If you aren’t doing virtualization today, the short-and-sweet of the benefits are these – quicker time to bring up a new server on an existing project, potential reduction in hardware (though not necessarily dollar savings, since VMWare isn’t free), unanticipated standardization of images (cloning becomes your friend, making all servers look similar), more responsiveness – ten minutes to bring up a VM or the purchasing process to get new hardware? The primary drawback is political… We’ve been purchasing servers by project, and that model needs tweaking in a virtualized environment. The first big problem is Virtualization. Most shops have started implementing, many are to the point where it is the standard method of deploying new servers. This is good, but early adopters of virtualized everything are showing the growing pains. Virtualization Sprawl is not just a catchy term, it is a real problem. Once you reach the point where VMs are the replacement for what used to be physical servers, you need policy and procedure to manage that inventory like you would have physical servers. There are several sound reasons for this statement – first is resource utilization (which I’ll delve deeper into in a future blog), second is security, the third is talked about below – the storage explosion is sometimes exacerbated by VM copies lying about – and getting replicated – when they’re not in use. Some shops have moved to some virtual infrastructure, with Lori’s whitepaper (pdf, in related articles list below, so just keep reading) being a good guide to a mixed vADC/pADC environment. So depending upon where your organization is at on the deployment scale, I would be doing one of the following
CLOUD – Control and Education
The cloud is coming. Lori and some others believe that public cloud will be part of your infrastructure, like it or not. I disagree with that bit, but you will indeed have cloud discussions over the next 6-12 months that, depending upon your corporate culture, will be combative or informative. I prefer to inform and educate where possible, but if you have that business owner that thinks he is not getting proper service from you, well you may end up in the “public cloud will be part of your infrastructure” boat. Let’s hope not though. There are several definitions for cloud still being floated out there, and there are several different aspects of cloud that you can consider. The most appealing to me (remember I’m a storage guy) is cloud storage, but there are some issues with storage in the cloud today. More on this in a future blog, but consider a cloud gateway as a short-term solution to what I call the cloud storage accessibility conundrum. If it makes your cloud storage look and (mostly) feel local, that solves one big problem, the other is security. Today the files you move to the cloud that might contain sensitive information should be encrypted. That statement will likely change as time goes on, but for now, that’s truth. Another bit that is intriguing me more and more is the idea of DMZ apps in the cloud. If you can drop your web server on someone else’s turf and they’ll guarantee both uptime and dynamic response to changing usage patterns, then all you need is something like our EDGE Gateway to secure that server’s connection to your DB. Concerns about shared hardware are much less when we’re talking a web server that is already out on the public Internet getting attacked. But you need to do several things now, to pave the way for a successful cloud deployment. If you haven’t yet, go read Lori’s blog on taking control of public cloud, it’s a good read on the potential issues you need to head off. Following that, I’d be talking and educating. The following are the points the business needs to understand:
STORAGE – reign in, improve usage
Storage has come such a long way in such a short time! There is so much you can do today that even five years ago wasn’t an option – converged networks, primary data de-duplication, a variety of options for where you store information… But this stuff all takes time. Figure out what fits with your organization and start reviewing it for suitability to your needs. Here’s a short list, no doubt others will think of other options for you to consider. Just assign people to start researching, don’t rush off to implement until you’re sure what you’re getting suits your needs.
That’s a start! That’s my top three for the next six to twelve months. Sure, things like SSD might be appealing too, but that is much more dependent upon the moment-to-moment speed requirements of your specific applications than the above are, so I left it off. Though this cycle waxes and wanes, I like some others believe we should consider re-instituting the chargeback model where cloud services (internal or external) are concerned. It makes a lot more sense in a cloud environment where they’re paying for a service, and will make business owners think about how much they actually need. Though they’re terribly unpopular with most business owners, so I’m only making a generalization. These are things that either are impacting you, could make your life easier, or will be impacting you soon. That’s why I’d spend research and education time on them now. No doubt there are others with different advice, if you’re one of those people, feel free to blog your version of this post and link back to us. If there are enough I’ll create a directory of blogs in this vein. Of course my thoughts are influenced by both my employer and my job, but I think these are in line with what’s worrying you the most technologically. Reader Feedback: Page 1 of 1
