A recent research report from 451 Research states that only 16 percent of businesses use just single cloud infrastructure. Two-thirds of the respondents in the survey mentioned about having a strategy in place for a hybrid approach. The report also mentions that most of the enterprises which are in the initial stages of cloud adoption are the ones that generally use one cloud. The investigation report gives two probable reasons behind it—they assess operational challenges of migrating or if they're only pushing a few workloads into the cloud as they keep sensitive data on premise.

However, the analyst house's survey of 1,500 CIOs and IT managers at large enterprises in partnership with TT Com and Dell EMC found out that around 84 percent of businesses are using multiple clouds for enhanced speed and agility. The next step in this process is the adoption of hybrid cloud, which forms an environment that brings a high degree of interoperation and integrated management. But 451 Research report advises that traditional measures like firewalls and access controls are not enough for security and they need to be re-tooled for hybrid environments, which require integrated tools designed for the cloud.

Damian Skendrovic, CEO, NTT Com Managed Services, the global managed services arm of NTT Com believes that there are several reasons for the enterprises’ increased interest in hybrid cloud. He says enhancement of the speed of deployment of applications and services to improve business agility is one of them. But he also warns about the challenges it poses. “At the same time this poses challenges including security management, operational complexity and legacy migration,” Skendrovic adds.
