gave the world a gift - the virtual machine (VM). A tragic waste of company capital and environmental resources! Hello VMware!Īmid all of this, VMware, Inc. This resulted in over-powered servers operating as low as 5-10% of their potential capacity. After all, the last thing anyone wanted, including the business, was under-powered servers unable to execute transactions and potentially losing customers and revenue. Most of the time nobody knew the performance requirements of the new application, forcing the IT department to make guesses when choosing the model and size of the server to buy.Īs a result, IT did the only thing it could do - it bought big fast servers that cost a lot of money.

The open-systems world of Windows and Linux just didn’t have the technologies to safely and securely run multiple applications on the same server.Īs a result, the story went something like this… Every time the business needed a new application, the IT department would buy a new server. In the past we could only run one application per server. The bad old daysĪpplications are at the heart of businesses. In this chapter we’ll get into things like why we have containers, what they do for us, and where we can use them. Finally, you’ll deploy apps with Docker stacks and secure your Docker environment.īy the end of this book, you’ll be well-versed in Docker and containers and have developed the skills to create, deploy, and run applications on the cloud. You’ll also build Docker networks and Docker overlay networks and handle applications that write persistent data. You’ll learn techniques for containerizing an app, deploying apps with Docker Compose, and managing cloud-native applications with Swarm. The book then turns its attention to the more technical aspects, guiding your through practical exercises covering Docker engine, Docker images, and Docker containers.

Once you’ve understood the Ops and Dev perspective of Docker, you’ll be able to see the big picture and understand what Docker exactly does.
#MAC OS DOCKER BIG SIZE INSTALL#
You’ll then get an overview of VMware, Kubernetes, and Docker and learn to install Docker on Windows, Mac, and Linux. The book begins with an introduction to containers and explains its functionality and application in the real world. With this book, you’ll gain the skills you need to work with Docker and its containers. Having impeccable knowledge of Docker will help you to thrive in the modern cloud-first world. Most applications, even the funky cloud-native microservices ones, need high-performance, production-grade infrastructure to run on.
