Focus on the Right Thing about Containers: What the Workloads Perform, not How They Do It

Much attention has been placed on modern applications and containers, and perhaps to excess. People wrote and worried about the choice of container orchestration systems—whether it’s Kubernetes, Marathon, or Swarm.

Also silly are comparisons of containers as a replacement for virtual machines, or whether serverless systems, such as AWS Lambda, are the new replacement for containers. Much of that was due to misconceptions, a desire to see a horse race where none exists, or a side effect of in-fighting in the open source community, with sponsoring organizations or vendors in the sidelines.

Nothing in IT Really Ends - Capisce? (Video)

I recently spent a little time in Italy, where I realized that whether in life or IT, nothing ever really goes away.

AD&D 2016 Predictions: Containers Will Go Mainstream

As part of my research planning for 2016, I sat down with ESG VP John McKnight to talk about application development and deployment predictions for 2016. Containers have been receiving a lot of attention in the last 18 months. Given the concerns that exist over container security and manageability I would have bet against this prediction at the end of 2015.

Container adoption likely to increase across hybrid clouds

2016 may be remembered as the year that container technology began to firmly take root across many data center environments. Case in point — 36% of users in ESG’s soon-to-be-published hybrid cloud survey indicated they are currently using containers in a limited capacity, with an additional 32% reporting they are currently testing containers. Perhaps more telling is the fact that only 4% reported they have no plans at all to use containers.

2016 Cybersecurity Radar Screen

Instead of making 2016 predictions in December, I decided to kick off the new year by sharing what’s on my cybersecurity radar screen for 2016. Given fundamental changes in computing models from cloud to mobility to IoT; the complexity of the threat landscape with hacker motivations of cybercrime, espionage, and activism; and the multitude of technology and solution providers; one’s radar screen quickly fills with more blips than can be reasonably tracked. And so I somewhat reluctantly offer up just a few threads of particular interest. But before looking at 2016, here’s a positive retrospective thought about 2015.

The battle between containers and VMs

A titanic battle is looming over the IT horizon: containers vs. virtual machines. Hypervisors like VMware’s vSphere have held hegemonic sway over the virtualized server infrastructure landscape for more than a decade. But now the age of the hypervisor seems to be in peril.

Docker Networking - Keeping it Simple

VMware's Project Bonneville - Containing the Container Contagion?

Containers, Docker, Kubernetes. What do all of these things have in common? From VMware’s perspective, they represent an existential threat to their hypervisor world order. Enter “Project Bonneville” - a VMware initiative to maintain the vSphere order of things by intertwining the roles of containers and VMs on server infrastructure. 

By VMware’s own admission, containers and hypervisors essentially do the same thing. They both abstract resources on a physical server. The difference is that hypervisors, like vSphere, virtualize the hardware while containers virtualize software--in this instance, the host operating system.

Will Googles’ Kubernetes become the GodFather of OpenStack Cloud Container Management?

Google’s recent announcement to become a sponsor of the OpenStack foundation was a virtual coup for the open source community. With the likes of traditional technology vendors like IBM, HP, Cisco, EMC, Red Hat and others already onboard the OpenStack bandwagon, adding Google to this prestigious mix nicely rounds out the foundation’s “Who’s Who” of technology luminaries.
