We’re in a new era of hybrid cloud computing, where IT managers regularly use a mix of private and public cloud services to scale up their computing capabilities whenever needed.
“With more companies moving to hybrid cloud, I expect a lot of new stuff to happen in enterprises that's never happened before,” said Rajiv Mirani, CTO of Cloud Platforms for Nutanix.
Over 90% of companies surveyed in the Nutanix Enterprise Cloud Index said that hybrid cloud is the ideal IT model. This matches with the results of other surveys, too, like the IDG report, which showed that 42 percent of organizations are using multi-cloud, either with or without hybrid cloud, to reap the benefits that include increased availability and more flexibility.
While the hybrid cloud model is relatively new, some IT pros remember the term hybrid cloud bursting — when an application runs in a private cloud or data center and “bursts” into the public cloud as the demand for computing capacity spikes. The rise of public cloud services has proven to be tremendously useful and disruptive. The pay-as-you-go model as well as their reliable performance and cutting-edge agility attracted droves of application makers and businesses. Many even saw public cloud as the end of private data centers.
Back in 2016, Forbes asked whether cloud would make corporate data centers obsolete. Even last year, ZDNet reported that cloud would replace traditional data centers by 2021.
Now, however, the reverse is true. Companies are moving more applications from public clouds back to their own data centers, according to Michelle Bailey, research fellow for data center and cloud market research firm IDC. At the 2019 IGEL Disrupt conference in San Jose, Calif., she projected that companies will repatriate 50 percent of their applications from public cloud back to company-owned and managed IT infrastructure. Some see the movement as even larger: Michael Dell, CEO of Dell Technologies, told CRN that 80 percent of workloads are being repatriated due to cost, security, and performance.
