![]() ![]() It emulates hardware like the CPU, RAM and I/O devices. Virtual machines are based on the concept of virtualisation, which is the emulation of computer hardware. Container technologies such as Docker beat VMs at this point in the cloud or data centre game. And yes, containers can enable your company to pack a lot more applications into a single physical server than a VM can. This quickly adds up to a lot of RAM and CPU cycles. Each VM runs not just a full copy of an operating system, but a virtual copy of all the hardware that the operating system needs to run. They take up a lot of system resources and are also very slow to move around. ![]() Virtual machines (VMs) run on top of a hypervisor with a fully virtualised and totally isolated OS. Which of the two is selected depends entirely on the specific needs of the end user. But just because containers are extremely popular, that doesn’t mean virtual machines are out of date. ![]() Some of the companies investing in Docker and containers are Google, Microsoft and IBM. Docker Cloud can also store pre-built images, or link to your source code so it can build the code into Docker images, and optionally test the resulting images before pushing them to a repository. It also allows you to publish Dockerised images on the Internet either publicly or privately. More are likely to follow soon, and you may be able to use the generic driver for other hosts.ĭocker Cloud provides a hosted registry service with build and testing facilities for Dockerised application images, tools to help you set up and manage host infrastructure, and application life cycle features to automate deploying (and redeploying) services created from images. Google’s container hosting and management service is underpinned by Kubernetes, its own open source project that powers many large container-based infrastructures. Today we have native support for nine major cloud providers:ĪWS is the biggest cloud-hosting service on the planet and offers support for Docker across most of its standard EC2 machines. If you already have an account with an Infrastructure-as-a-Service (IaaS) provider, you can provision new nodes directly from within Docker Cloud, which can play a crucial role in digital transformation.įor many hosting providers, the easiest way to deploy and manage containers is via Docker Machine drivers. But seamlessly transitioning our honed application stacks from development to production is problematic.ĭocker Cloud makes it easy to provision nodes from existing cloud providers. We all know that Docker is simple to get up and running on our local machines. As it becomes increasingly popular, let’s look at what the future holds for Docker. This is a discussion on the role of Docker in software development and how it scores over virtual machines. ![]()
