Lately, it seems, quite a few technology players are jumping on the composable infrastructure bandwagon, claiming that their take on a modern infrastructure is a truly composable one. I beg to differ. Upon inspection, many of these offerings appear to be piecemeal efforts dedicated to some part of the infrastructure, rather than the whole.

Historically, computer systems have been designed with a focus on optimizing application performance. The ability to run applications faster is obviously an important attribute of IT infrastructure. Yet, in recent years, customers have begun looking more closely at optimizing the speed of service delivery. In this new paradigm, IT is transforming from a cost center to a profit center by creating new revenue streams with sleek mobile-first and user-friendly big data applications. Since faster time to market means profits sooner, time to market is becoming a critical metric.
Today’s business environment is evolving into a digital ecosystem, and that ecosystem must support a very digital user. What’s fascinating is the pace and acceleration of this evolution. Mobility, the Internet of Things and the growth of cloud are all impacting services--and entire go-to-market strategies. Through it all, companies need their technology to keep up with evolving consumer and business demands.

If you listen to some vendors, there is no need for on-premises infrastructure anymore. Everything that you want to do you, you can do in the cloud. All you need to do is rent the infrastructure--no capital expenditure cost, just ongoing usage-based operational expenditures. The reality isn’t quite that straightforward.
