Enterprise embrace of Docker containers may take time

Interesting notes:

But even with the building momentum, the uses are largely limited to cloud-first, Web-based companies, said Bartoletti, who doesn't expect much production use of Docker among enterprises until 2016.

"It hasn't really had any major penetration in the data center yet," Bartoletti said. "The reason it's taking off so quickly is it's really being driven by the development teams, not IT right now."

Docker's focus has been with development vs Glassware is directed towards simplicity of containerizing an application for IT departments. To really take advantage of docker, you need to package it within a container. This can only be done if you have access to the application's source code and modify it to be inside a container. With Glassware, you just need the installer.

Many open source projects get plenty of hype but receive very little production use in the first couple years, Bartoletti said.

Still, enterprises shouldn't be scared to use Docker, especially those that see portability as key to success, said David Linthicum, senior vice president of consulting firm Cloud Technology Partners, Inc., based in Boston. Containers should be considered as part of a broader strategy -- but it's probably best to do proof of concepts and let others jump in first and work through the kinks, he added.

Any new software needs to prove itself first. Even Glassware.

Docker has gained traction with ISVs and Web-scale companies that run a single application stack, but enterprises face a bigger challenge of integrating Docker into heterogeneous workloads, Ghosh said.

"The old legacy apps aren't architected that way," Ghosh said. "Some could move, but the reality is you will take new things and put them all on Docker. That will take a while."

Glassware addresses this. For "heterogenous workloads" (correct me if I'm wrong) I think it means the ability to scale out and cluster the app container technology. So with Glassware, that would be adding Glassware appliances to a cluster of other appliances.
