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 introduction, for those who don’t know, I’m relatively conservative in my use of IT, I’ve been around the block, been burned a few times (OS/2 Beta Tester, WFW, WP...The list goes on), and the organizations I’ve worked for where I was part of “Enterprise IT” were all relatively conservative (Utilities, Financials), while the organizations i worked in Product or App Development for were all relatively cutting edge. I’ve got a background in architecture, App Dev, and large systems projects, and think that IT Management is (sadly) 50% corporate politics and 50% actually managing IT. I’ll focus on problems that we all have in general here, rather than a certain vertical, and most of these problems are applicable to all but the largest and smallest IT shops today.

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

  • Considering increased IT responsiveness and agility with virtualization
  • Planning for an overall virtualized environment including automation, which is lacking today
  • Figuring out how to manage VMs in an efficient manner that optimizes server utilization
  • Working out an infrastructure to insure that Virtualization does not become a hindrance

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:

  • “Cloud Services” that claim to be developer-free aren’t going to be integrated with corporate data, nor are they generally going to pass security audits.
  • Cloud Services that offer file storage offer astounding availability, but ask them about security and screen candidate files appropriately.
  • The corporation will be held responsible for corporate data no matter where it is stored. Caution must be used when talking about customer PID.
  • Cloud Services that offer to extend data center functionality have a high probability of usefulness, but must be evaluated for integration with the DC.
  • IT Management will not be held responsible for data others place in the cloud, so IT should be involved early in evaluation of suitability to the cloud.
  • WAN Optimization. If you are going to be dealing with public cloud over constrained or shared lines, you need to know what’s available to you to speed up that communication. If you have more than one data center this isn’t a bad idea anyway, but we’re in the cloud section, so think of the volume of data you’re likely to be shipping to the cloud and the size of your existing pipe. You can upgrade the pipe for a monthly fee or check out products like our WOM and EDGE Gateway.  EDGE Gateway is more appealing if you want to extend access control to the link shared with the cloud.
  • If you’re considering a private cloud, then schedule brown-bags or meetings to help business owners understand the difference between internal cloud and external cloud.

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.

  • At-rest De-duplication, be it primary or not. This is currently the buzz of the storage world, led by NetApp. Make sure that the background processing fits within your levels of service, and that the de-duplication process is reliable and reversible. Today they generally are reliable and reversible, but I don’t know what vendors you will end up with, so check into it, ask for customer references.
  • De-duplication at store, be it primary or not. This is de-dupe as writes are performed. It is EMC’s Data Domain based solution to primary storage de-dupe and is also available for many other platforms. Again, check it out, ask for references, make sure you know what you’re getting.
  • Cloud Storage Gateways. I have a personal opinion on these and where they’re headed, but you should build an informed opinion based upon research in your own environment. The idea of local cache with remote write is appealing, but these do not say anything about the security and availability of the cloud provider you set them up to write to.
  • Cloud Storage in general. Remember that you pay for what you use, so this can be a painful problem if you don’t have good control of your storage. But as a place to deposit encrypted backups? Why the heck not? Well, that’s what the research would be to determine… Why the heck not, what other use cases fit your organization, etc.
  • If you’re not already doing it, file virtualization. Let’s face it, a simplified storage interface with security improvements is in-line with the type of savings gained from server virtualization. We offer our ARX product line to help with this and Data Manager to help you understand what you’ve got stored where. There are other products in the same space, but of course I  don’t think they’re our equal ;-). If you are a homogenous storage shop, there is likely a vendor-specific solution to this problem for you, but there just aren’t a ton of single-vendor storage shops out there, never were.

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.

While some developers care passionately about how data centers and clouds are architected, for most, it is only the end result that matters. To the majority of companies, technology exists to solve a business problem, and only delivers value when it is solving that problem. 2017 brings the mainstream adoption of containers for production workloads. In his session at 21st Cloud Expo, Ben McCormack, VP of Operations at Evernote, discussed how data centers of the future will be managed, how the p...
The nature of test environments is inherently temporary—you set up an environment, run through an automated test suite, and then tear down the environment. If you can reduce the cycle time for this process down to hours or minutes, then you may be able to cut your test environment budgets considerably. The impact of cloud adoption on test environments is a valuable advancement in both cost savings and agility. The on-demand model takes advantage of public cloud APIs requiring only payment for t...
It has never been a better time to be a developer! Thanks to cloud computing, deploying our applications is much easier than it used to be. How we deploy our apps continues to evolve thanks to cloud hosting, Platform-as-a-Service (PaaS), and now Function-as-a-Service. FaaS is the concept of serverless computing via serverless architectures. Software developers can leverage this to deploy an individual "function", action, or piece of business logic. They are expected to start within milliseconds...

You know you need the cloud, but you’re hesitant to simply dump everything at Amazon since you know that not all workloads are suitable for cloud. You know that you want the kind of ease of use and scalability that you get with public cloud, but your applications are architected in a way that makes the public cloud a non-starter. You’re looking at private cloud solutions based on hyperconverged infrastructure, but you’re concerned with the limits inherent in those technologies.

The cloud era has reached the stage where it is no longer a question of whether a company should migrate, but when. Enterprises have embraced the outsourcing of where their various applications are stored and who manages them, saving significant investment along the way. Plus, the cloud has become a defining competitive edge. Companies that fail to successfully adapt risk failure. The media, of course, continues to extol the virtues of the cloud, including how easy it is to get there. Migrating...
For DevOps teams, the concepts behind service-oriented architecture (SOA) are nothing new. A style of software design initially made popular in the 1990s, SOA was an alternative to a monolithic application; essentially a collection of coarse-grained components that communicated with each other. Communication would involve either simple data passing or two or more services coordinating some activity. SOA served as a valid approach to solving many architectural problems faced by businesses, as app...
Some journey to cloud on a mission, others, a deadline. Change management is useful when migrating to public, private or hybrid cloud environments in either case. For most, stakeholder engagement peaks during the planning and post migration phases of a project. Legacy engagements are fairly direct: projects follow a linear progression of activities (the “waterfall” approach) – change managers and application coders work from the same functional and technical requirements. Enablement and develo...
Gone are the days when application development was the daunting task of the highly skilled developers backed with strong IT skills, low code application development has democratized app development and empowered a new generation of citizen developers. There was a time when app development was in the domain of people with complex coding and technical skills. We called these people by various names like programmers, coders, techies, and they usually worked in a world oblivious of the everyday pri...
From manual human effort the world is slowly paving its way to a new space where most process are getting replaced with tools and systems to improve efficiency and bring down operational costs. Automation is the next big thing and low code platforms are fueling it in a significant way. The Automation era is here.

DevOps is good for organizations. According to the soon to be released State of DevOps Report high-performing IT organizations are 2X more likely to exceed profitability, market share, and productivity goals. But how do they do it? How do they use DevOps to drive value and differentiate their companies? We recently sat down with Nicole Forsgren, CEO and Chief Scientist at DORA (DevOps Research and Assessment) and lead investigator for the State of DevOps Report, to discuss the role of measure...
DevOps is under attack because developers don’t want to mess with infrastructure. They will happily own their code into production, but want to use platforms instead of raw automation. That’s changing the landscape that we understand as DevOps with both architecture concepts (CloudNative) and process redefinition (SRE). Rob Hirschfeld’s recent work in Kubernetes operations has led to the conclusion that containers and related platforms have changed the way we should be thinking about DevOps and...
"As we've gone out into the public cloud we've seen that over time we may have lost a few things - we've lost control, we've given up cost to a certain extent, and then security, flexibility," explained Steve Conner, VP of Sales at Cloudistics,in this SYS-CON.tv interview at 20th Cloud Expo, held June 6-8, 2017, at the Javits Center in New York City, NY.
These days, APIs have become an integral part of the digital transformation journey for all enterprises. Every digital innovation story is connected to APIs . But have you ever pondered over to know what are the source of these APIs? Let me explain - APIs sources can be varied, internal or external, solving different purposes, but mostly categorized into the following two categories. Data lakes is a term used to represent disconnected but relevant data that are used by various business units wit...
With continuous delivery (CD) almost always in the spotlight, continuous integration (CI) is often left out in the cold. Indeed, it's been in use for so long and so widely, we often take the model for granted. So what is CI and how can you make the most of it? This blog is intended to answer those questions. Before we step into examining CI, we need to look back. Software developers often work in small teams and modularity, and need to integrate their changes with the rest of the project code b...
