But, if you take a bit of managed hosting or colocation, throw in some cloud computing and a couple of legacy systems — you get an IT environment that makes offering a seamless user experience a huge challenge, and that is almost too complex to manage. To make these multiple legacy and cloud environments work better together while increasing business agility, more and more enterprises are turning to hybrid IT.
How to make hybrid IT work
Instead of forcing every enterprise IT need into the same model, hybrid IT uses the best approach to solve each business problem, and harnesses the best suited part of the IT infrastructure — public or private cloud, hosted environment — saving time, money and resources. But, the move to a new kind of hybrid IT environment requires a thoughtful, step-by-step approach — not a great leap forward. Several considerations in the process include, where should different kinds of workloads run? How will you develop new applications for it? What kinds of tools are required to manage this new environment? Where should different kinds of data be stored?
Crucially, when embarking on a hybrid IT journey, you need to consider the number of applications your business uses and the different cloud environments deployed. A large enterprise might have 500 or more applications running through its IT infrastructure. You will need to compile an inventory of them all and determine which ones are still useful. Most enterprises also use multiple clouds — private, public and hybrid — but don't always know what their clouds are doing, or how well they are performing, so you need a cloud inventory and determine what services and applications are running in each.
Become more nimble
While cloud computing is helping enterprises to respond more quickly to fast-changing market demands and competitive pressures, it can also increase complexity for the IT department. Hybrid IT gives you the best both worlds — scalability of different clouds with the security and reliability of traditional infrastructures — and represents a fundamental shift in how the IT department works. Ultimately, hybrid IT puts the CIO back in control and enhances business agility and innovation, accelerating time-to-market, and empowering the whole organisation to nimbly capitalise on new growth opportunities.
