Virtualization has always been a rich man's game, and more frugal enthusiasts—unable to afford fancy server-class components—often struggle to keep up. Linux provides free high-quality hypervisors, but when you start to throw real workloads at the host, its resources become saturated quickly. No amount of spare RAM shoved into an old Dell desktop is going to remedy this situation. If a properly decked-out host is out of your reach, you might want to consider containers instead. </div> </div> </article> </div> <div class="views-row"><article data-history-node-id="1340761" role="article" about="/content/how-build-enterprise-kubernetes-strategy" class="special-content teaser clearfix"> <div class="teaser-image"> </div> <div class="teaser-text"> <div class="special-message">Sponsored Content</div> <h2> <a href="/content/how-build-enterprise-kubernetes-strategy" rel="bookmark"> <span>How to Build an Enterprise Kubernetes Strategy</span> </a> </h2> <footer> <div class="author"> <span><a title="View user profile." href="/user/800005" lang="" about="/user/800005" typeof="schema:Person" property="schema:name" datatype="">LJ Staff</a></span> - July 21, 2019 </div> </footer> <div class="content-body"> In today’s emerging cloud-native environments, Kubernetes is everywhere.

The recent rise in popularity of container technology within the data center is a direct result of its portability and ability to isolate working environments, thus limiting its impact and overall footprint to the underlying computing system. To understand the technology completely, you first need to understand the many pieces that make it all possible. Join us this weekend as we learn about Containers. Before we get started, many ask what the difference is between a container and virtual machines? Editor Petros Koutoupis explains: Both have a specific purpose and place with very little overlap, and one doesn't obsolete the other. A container is meant to be a lightweight environment that you spin up to host one to a few isolated applications at bare-metal performance. You should opt for virtual machines when you want to host an entire operating system or ecosystem or maybe to run applications incompatible with the underlying environment. </div> </div> </article> </div> <div class="views-row"><article data-history-node-id="1340036" role="article" about="/content/sharing-docker-containers-across-devops-environments" class="story is-promoted teaser clearfix"> <div class="teaser-image"> </div> <div class="teaser-text"> <h2> <a href="/content/sharing-docker-containers-across-devops-environments" rel="bookmark"> <span>Sharing Docker Containers across DevOps Environments</span> </a> </h2> <footer> <div class="author"> <span><a title="View user profile." href="/users/todd-jacobs" lang="" about="/users/todd-jacobs" typeof="schema:Person" property="schema:name" datatype="">Todd A.
