How Docker revolution impacts Cloud Industry?
It seems the future cloud industry is expected to undergo a revolution with the concept called” Containerization”. It is a powerful mechanism to package and deploy tools. The world’s leading software container platform, Docker helps developers to eliminate “works on my machine” problems. In order to get better compute density, operators are using Docker to run and manage apps side-by-side in isolated containers. Meanwhile, business owners are using Docker to build agile software delivery pipelines where they can ship new features faster, more securely and with confidence for both Linux and Windows Server apps. Can we expect the Docker concept to change the current cloud trends? Well, this blog will help you to understand how this containerization tool is going to change the cloud industry in 2017.
The Cloud Revolution with Docker
Containers can be utilised in order to make a piece of ‘software run’ which is packaged into isolated containers. The difference between the VMs and the containers is that the former will not bundle a full operating system but only set up the libraries and settings required to make the software work effectively. So it makes lightweight, efficient and self-contained systems to run the same software regardless of where it’s deployed. The emergence of Docker has impacted the cloud industry in the following ways:
The Portability Feature
Why is Docker so unique? Due to the Portability feature, the users no longer require a virtual machine to spin up each and every app. If you are running a CoreOS host server and have a guest Container based on Ubuntu, then the Docker has the parts which make Ubuntu different from CoreOS. When the Docker is defined as an isolated portion of the host computer that shares the host kernel (OS) and its binaries/libraries, the Virtual Machine is defined as a whole guest computer that runs on top of your host computer.
In terms of system resources, shared Kernel used by Dockers is more efficient than hypervisors. Since Containers are lightweight, there are several VMs that run the application with its own operating system. In order to execute the work, there can be thousands of containers in the same server that shares the Kernel’s operating system. It helps the user to leave behind the useless 99.9% VM junk. So your applications can be stored in a small and neat capsule.
Easy to Launch
The project called Libswarm launched by Docker would potentially make it easier to use containers in public cloud. Earlier for running a remote cloud server, the user has to log into cloud server and is required to push the image which has access to the Docker Registry. Only after that, you can pull that image down to the cloud server. Then the cloud server will be all set to launch the container. The Docker- Libswarm can be configured once but it can create all of your Docker images locally. It deals with orchestration and creation in order to start the container.
Great Developer Experience
Using Docker, you can reduce onboarding time by 65%. Without wasting the time in installing and maintaining software on servers and developer machines, the developers can build, test and run complex multi-container apps. So that the “work on my machine” constraints getting eliminated.
Easy Distribution and Sharing of Content
You can develop, manage and distribute images in secure Docker Registries located on-premises or in the cloud. The configurations, content updates and build history are automatically synchronized across the organization. The formatting engine of Docker has become a platform where lots of tools and workflows are attached. Also, the containers are getting support from the largest vendors like Red Hat and Microsoft. In last July they all, along with Docker, joined Google for the Kubernetes project which is an open source container management system for managing Linux containers as a single system. Even the global players are exploring containers which will create a drastic change in the Distribution and Sharing Of Content through cloud platforms.
Docker is the backbone of the modern app platform, connecting developer, and IT, Linux and Windows. Docker works in the cloud platforms as well as in on-premises; It supports both micro, traditional, and service architectures. Use Docker to build, secure, network, and schedule containers and manage them throughout the development process. The involvement of Docker will help the enterprises on the path to digital transformation by enabling all apps to be cloud-ready, agile, and secure at optimal costs.
