The art of managing IT risk is never quite mastered
Risks abound, and no amount of preparation or caution will eliminate them entirely from our lives. This is as true now as it was in the past, and it likely will remain true in the future.
While technology enables us all to work more effectively and productively, the necessity of managing IT risk remains. Risk follows wherever we go -- from the data center to the cloud, from virtualized workloads to containers. Smart IT organizations are continuously assessing threats and then devising ways to minimize them. That's the goal, at least.
This issue of Modern Infrastructure examines some of the current approaches to managing IT risk, from maintaining security to handling costs.
In our cover story, TechTarget's Beth Pariseau writes about the particular challenges of container security. IT shops have been reluctant to put containers in production in large part because of the uncertainty about how secure they might be. Updates from Docker and more disciplined app development practices are making containers less risky, Pariseau writes. And there's reason to think that containers could be even more secure than VMs.
Getting comfortable with containers is a process not unlike how technology professionals learned how to safely use cloud services. It takes some time and effort, but managing IT risk can bring exciting and powerful new tools safely into the fold.

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.
