These benefits can include agility, scalability, lower cost, and innovation and require heavy reliance on automation rather than manual legacy processes. Technologies leaders with legacy thinking are faced with harsh trade-offs between control and the benefits of cloud.

Similar differences abound in security management and workload reliability. In the cloud, however, an enterprise might have 500 virtual machines one minute and 5,000 a few minutes later when autoscaling functions engage to meet demand. These items are relatively easy to control because they require management approval and are usually subject to rigid oversight. When thinking about cost governance, for example, in an on-premises infrastructure world, costs increase in increments when we purchase equipment, sign a vendor contract, or hire staff. This is the case particularly in security, reliability, and cost governance. Migrating legacy processes, tools, and human skillsets to the cloud is a recipe for failure. Another study from IHS Markit found that 74% of companies have attempted to move applications to the cloud only to have to move them back on premises.ДЇailure in the cloud most often results when IT leaders fail to appreciate the extent to which completely different ways of thinking are required in the cloud. Cloud Security AllianceвЂ™s 2019 Impact of Cloud on ERP survey found that 90% of CIOs have experienced failed or disrupted cloud efforts. Johnson is not alone in his observations. Migrating to the cloud on-time and within budget is difficult in and of itself. ThatвЂ™s part of what makes cloud initiatives highly complex and why so many of them fail. вЂњThe traditional static way of thinking makes it really difficult to effectively align overall business strategy with cloud strategy. вЂњMost technology leaders have a difficult time thinking in terms of an infrastructure that is fluid and dynamic,вЂќ says Kenneth Johnson, a cloud strategist for Blue Sentry Cloud, a company that specializes in complex enterprise cloud initiatives. That is certainly the case for cloud computing.ДЄnd it is this propensity for constant change, the very nature of cloud, to which IT leaders struggle to adapt, leading to high rates of failure for cloud initiatives. In a 2011 article in The Atlantic, senior editor Rebecca Rosen makes the case that clouds may be the most useful metaphor of all time, in part because they are constantly changing.
