By 2022, over 90% of global enterprises will rely on a mix of on-premises/dedicated private clouds, multiple public clouds and legacy platforms, IDC reports, marking 2021 as the year of multi-cloud.
"The widespread disruption caused by the global Covid-19 outbreak has reinforced the critical importance of businesses being agile enough to scale up or down with fluctuations in demand," the analyst says. "A public cloud platform provides enterprises with an agile, scalable, and cost-effective IT infrastructure that supports their business processes. However, public cloud is not necessarily an appropriate option for all types of workloads. As such, some enterprises are choosing to keep certain workloads on-premises-- using an in-house datacentre-- or on private clouds. This approach helps them achieve better performance, 24/7 availability, enhanced security and greater compliance with regulations."
Currently not all businesses are prepared to implement cloud roadmaps. In fact, IDC says just 30% of medium-to-large organisations highlight migration as a key challenge. In the meantime, 39% cite a lack of skills as an obstacle to cloud strategy rollout. As such, multi-cloud success requires a phased modernisation approach for each application in use, before making the appropriate decision for the multi-cloud era.
