“The results show that complexity — a common criticism of Kubernetes — is only the fifth most cited challenge. In the lead are infrastructure-related challenges. Security was cited by 46 percent of Kubernetes users, with networking and storage coming in second and third place.”

In the last 15 years, application delivery has moved from being bound to physical servers to running on virtual machines with a full operating system and now to containers with Docker where developers can specify every aspect of deployment, he added.
The move has also been a shift from a heavyweight application deployment model to a lightweight model that takes less time to start up and deploy applications. Additionally, there has been a move from being bound to a single closed-source vendor to an open-source model with multiple vendors, less risk of lock-in and more choice.
And, on the maturity front:
not all organizations are ready for the move, according to Donnie Berkholz, research director at 451 Group. He pointed to a recent survey his firm conducted that found that most IT organizations are still running lots of manual process and aren’t in the DevOps world, and many aren’t even using agile development methods either. For cloud native to make sense, organizations need to make use of continuous integration and continuous development technologies, Berkholz said.
“You can’t do cloud native if you don’t have the right processes to support it,” Berkholz said. “For some of the world, it’s a long way to go on the journey to cloud native, and it will take at least five years to get there.”
