To manage and monitor containers, understand their peculiarities

A good IT operations team is primed to worry about an application's availability and performance. It's a fundamental concern in every hour of every day. So when containers begin to deliver apps, an IT team needs to implement new methods to monitor containers -- and to adjust to new ways of worrying.

Container technology brings advantages to an IT infrastructure, particularly with improved use of resources. The value of containerization, at least from a technology point of view, is mostly clear by now. What holds back adoption is uncertainty over how to work with and monitor containers. They come in different formats. They are built through different methods. They behave in different ways. They require a management approach that is, yes, different.

Momentum behind containerization is building. A recent report from 451 Research pegged spending in the application container segment at $762 million in 2016; by 2020, that figure is projected to jump to $2.7 billion.

That kind of growth suggests containers are destined to find a place in plenty of IT shops, which makes learning about them -- and how to manage them -- an IT priority. This handbook tackles that mission, beginning with an overview from IT consultant Alastair Cooke on the best ways to manage and monitor containers -- either through native tools or emerging third-party products. There will be plenty of new tasks for IT admins to consider in a container environment. Also included are discussions of how Docker is adjusting its management tools and how container security is evolving as adoption begins to pick up.
