The hybrid cloud gives companies the reassurance that sensitive information, such as intellectual property or customer data, can still be stored and maintained within their own data centres. Increasingly, however, it's becoming mainstream: A recent survey from RightScale estimated that the number of enterprises with a hybrid cloud strategy grew to 58% in 2019, up from 51% in 2018. Hybrid cloud used to be quite a niche model, with some industry watchers claiming it was just a step on the way to the full public cloud.
Local laws may also restrict what kinds of information might be stored in a third-party service, too, meaning organistions often appreciate the flexibility that hybrid cloud configurations offer. Long-term storage, however, can often be cheaper in a private cloud than in a public cloud, so businesses will need to dip into both depending on the circumstances.
Spinning up some cloud instances for a time-limited project and turning them off when no longer required may be relatively inexpensive compared with provisioning extra capacity in an on-premise data centre. We refer to private cloud as in-house and on-premise infrastructure, or managed services, while public cloud is offered by providers such as AWS and Azure. The difference between these two regimes, however, is the involvement of private and public cloud services. In this respect, hybrid cloud and multi-cloud setups have become more and more popular since they allow businesses to deploy their apps and services as they see fit. This is great for businesses, given the variety of options from which they can choose, with customers generally given more flexibility to fine-tune their IT estates in the ways which suit them best. As such, these entities themselves are also undergoing digital transformation efforts and reorganisations in order to stay relevant. It's a wide field, with various competing forces vying for new business. Some of the biggest tech companies have been central to these efforts, including Google, Microsoft and AWS - with Oracle, IBM and VMware also providing cloud services.
