More than half (61%) of enterprise employees are currently using or experimenting with Container as a Service technology, according to the RightScale 2019 State of the Cloud report from Flexera, released on Wednesday. The report outlines the current state of cloud centers and services, naming the most popular container tools for organizations.

The report surveyed 786 employees to determine their organizations’ cloud usage. Businesses are using nearly five clouds on average, with the priority being the public cloud, the report found. Optimizing cloud costs is the biggest challenge and top priority for business in 2019, the report and our sister site ZDNet noted.

Containers changed the way apps and services are deployed, as they are self-contained applications that IT teams can launch and update easily. Containers help fix the scalability issue that is accompanied by the thousands of virtual machines in the private and public cloud spheres. This tool is especially helpful in executing a multi-cloud approach in businesses.
