OpenStack infrastructure turns to containers

OpenStack is far from perfect. In fact, there are a number of hurdles it needs to clear before widespread adoption in the enterprise becomes a reality. However, a recent technology trend might just be what the OpenStack infrastructure needs, and it's one that many originally thought would be OpenStack's death sentence -- containers.

A recent study from OpenStack's user survey showed that containers generated the most interest among the community, a sign that IT is ready to take the leap from virtualization to containers. OpenStack leaders say containers are the central piece to the underlying cloud framework that OpenStack lives on.

Meanwhile, data analytics continues to drive the next wave of IT ops tools by combining input from various platforms to create predictive information for the enterprise. So where does IT go from here? Read on to find out.

Container orchestration for a new breed of IT

PaaS offerings such as Heroku, RedHat OpenShift and Cloud Foundry have always used containers under the covers, but as containers move toward production use outside of PaaS in the cloud, they're being deployed in clusters of server infrastructure that are orchestrated to automate the deployment of containers. So is container orchestration right for IT? Well, that depends.

Beth Pariseau's feature this month, 'A New Day for PaaS' analyzes the way IT views PaaS, and how it's evolving. On the other hand, IT pros must dish out reality every once in a while to the business side, and often 'live on the edge' according to Alan Earls. But life on the edge can be dangerous, and it isn't just a figurative turn of phrase anymore, it's a physical location.

Both these stories, and much more, including columns from Bob Plankers and Mike Matchett, and what enterprise IT is thinking about VMware in the May issue of Modern Infrastructure.
