The 8 Truths Of Enterprise IT...

Posted by Tom Foremski - July 29, 2010

Enterprise IT is notoriously conservative and resistant to any changes. Yet the enterprise IT market is massive and it's a market that is primed for change because of many innovative technologies.

However, it can be a very frustrating experience for companies targeting the enterprise IT market. Jake Sorofman, chief marketing officer for rPath, which provides solutions for automating system deployment and maintenance across physical, virtual and cloud environments, shares his theories on what makes enterprise IT tick.

1. Drift happens - Complex software systems are rarely consistent or what they ought to be. They drift and morph in definition over time as patches are applied, updates are made and IT personnel tunes, tweaks and fiddles. These changes are typically untracked, and IT rarely knows precisely what is running. When they're initially deployed, systems are opaque. Over time, they're complete mysteries.

2. Change hurts - IT fears and avoids change because of a Law of Unintended Consequences that hangs over the data center. At the heart of this law is the reality that deployed systems and their dependencies are poorly described and documented. When change happens, stuff breaks. This is why, on the topic of change, IT tends to channel Ross Perot: "If it ain't broke, don't fix it."

3. IT abhors a vacuum - As the cost of computing drops, workload demand increases. This is the force behind VM sprawl and the attendant growth in management costs. Like nature, IT abhors a vacuum. When space is made available, it's quickly filled in. (Perot may call this "a giant sucking sound.")

4. Demand follows the path of least resistance - Like it or not, enterprise IT competes with a marketplace of alternatives. When alternatives offer comparatively better options in price, performance and availability, workloads will follow the path of least resistance. Public cloud is a perfect example of this phenomenon at work: IT organizations that fail to transform will surely watch in vain as workloads, following the path of least resistance, escape to the cloud.

5. Dependencies grow geometrically - Software is more diverse than ever, comprising an unthinkable array of custom, commercial and open source options. This means that developers have more resources to ply their craft, and IT is utterly mired by complex, interdependent and constantly changing systems. It's made worse by the ongoing abstraction of IT, from managing discrete single-use piece parts to the composition of reusable services. The network of interdependency is massive and--much of the time--poorly understood.

6. So does scale - Each subsequent architectural advancement leads to an increase in scale. Scale exploded as mainframe gave way to client-server and client-server gave way to web. Today, we're seeing x86 architectures, virtualization and cloud are all driving growth in the volume of systems that need to be managed.

7. Proportionally, budgets will always contract - Operating budgets cannot keep pace with growth in IT scale, so even when the top-line budget is growing, the budget per managed system is always contracting. IT will always be forced to do more with less--forced to find new ways to change the economics of scale.

8. Complexity is the mother of reinvention - When IT complexity reaches the frontier of existing tools and processes, IT must reinvent. Containing complexity is like holding back a tide. The only way forward is through reinvention, embracing new tools and approaches for dealing with IT complexity at scale.

So that's it--eight IT truths as I see them. What truths do you see?
