Recently I attended DockerCon in Austin, Texas. Docker has been gaining an increased amount of interest in the enterprise for both building new greenfield applications and migrating legacy applications. Docker has become synonymous with microservices-based architectures, but enterprises are mired in legacy applications. In my experience, well over 90% of all workloads in enterprises are not microservices-based architectures, so I was interested in hearing how Docker would address this issue.

DockerCon 2017 was about modernizing traditional applications, or MTA. MTA is the lifting and shifting of traditional Microsoft Windows base applications into Docker containers. Its approach is reminiscent of 2009. For Docker to grow into brownfield data centers, this is a must. However, could it be doing more? If so, what is it doing that could be improved? MTA is a must for many organizations looking to Docker to manage everything, but not everything uses the same approach. Containers are about agility, with workloads being treated like cattle. Can traditional applications be treated this way? We shall see.
Software-defined storage (SDS) has usually meant storage that augments, optimizes, aggregates, and presents some form of cloud gateway. It is storage manipulated by an automation with an orchestration layer that ties differing data functions together. The ultimate in automation and orchestration for storage is the inclusion of Docker. Docker, or any container technology, needs storage—persistent storage. How storage is presented to Docker is unimportant to Docker. It is, however, important to the storage team. SDS is about making storage simpler by reusing, improving, or automating delivery. How does your storage fit with Docker?
RightScale just published its annual report on the state of the cloud, and some of the key findings are very interesting. Topics range from cloud vendor market share to cloud adoption concerns, DevOps tools adoption, public vs. private cloud adoption, and much more. Below, I highlight the major findings I thought most interesting and follow each with my perspective on it.
Docker, the leading vendor in the container industry, has been dipping into its pockets again, this time to acquire French file sync company Infinit. Yep, Docker, the company whose core product is a container management and deployment technology, is acquiring a consumer file sync company.
At first glance, this is an odd acquisition. Infinit is a company with a product that appears similar to Aspera, Accellion, or even good old-fashioned FTP. If you need to share your files, but email send or receive limits are getting in the way, Infinit allows you to create a Share directly to other Infinit users or a link that can be emailed to non–Infinit users to access your files directly, thereby allowing them to download them for review or further work.
When we were first introduced to Docker containers, we were told that they should be ephemeral and stateless. It turns out that there are lot of great uses for Docker containers that are either stateful or long-lived. The stateful part is leading to a bunch of startups that have storage products to deliver persistent storage to these stateful containers. Even our old friends at VMware are in on this game. Their Photon platform is going to include VSAN to provide persistent storage for containers.
