8 Containers For Dummies, HPE and Docker Special Edition These materials are © 2017 John Wiley & Sons, Inc. Any dissemination, distribution, or unauthorized use is strictly prohibited. containers running on an identical bare-metal host, they mea- sured up to 73 percent performance improvement (measured in transactions per second). That's significant! Plus, with contain- ers, workload portability takes on new meaning because shifting workloads between hosts and between local hosts and cloud- based ones becomes trivial. Containerized Application Support With the infrastructure discussion out of the way, I'll turn your attention to the reason you're here: workloads. After all, without workloads, you wouldn't need containers, virtualization, or even bare-metal servers. Traditional applications Those new to containers are often under the misconception that they work only with brand-new cloudlike applications. Not true! In fact, one of the key themes behind Docker's recent efforts is modernizing traditional applications. Moreover, deployment of applications is getting easier as more images are added to the Docker Store and as more traditional applications are containerized for easy consumption. Take, for example, Microsoft SQL Server. With just a few simple commands, you can pull a Linux-centric version of SQL Server from the Docker Store and be up and running in minutes. SQL Server is a great example of a traditional, enterprise-class appli- cation that you can deploy in Docker in just minutes. In fact, it's easier to deploy SQL Server on Docker than it is to deploy it as a legacy application on Windows! As you can see, this is all made easier with the Docker Store. Think of this as the app store for all things container. Need a robust graph database? Simply download the neo4j image from the Docker Store. Need Oracle Linux? There's a container for that, too. Plus, if you're worried about security and availability — and, these days, those worries are necessary — Docker Enterprise Edition can get certified containers via the Docker Store. Multiple categories of Docker Certified technology are available:
