Docker is a highly sought after software platform for containerization that has been transforming virtualization by enabling applications to run in multiple environments by boosting portability of cloud.

Highlights of Docker

Thanks to an extensive use of containers, developers are no more required to several virtual machines for separation of applications for users. Same holds true for programmers who need not be restricted to use particular languages. Docker is driving the paradigm shift by facilitating program management within software containers. It is perceived as a central pillar of container ecosystem along with many more solutions including Kubernetes for container deployment within a compute cluster.

Being an open source utility, Docker provides deployment automation and facilitates ease of system administration by running applications inside containers unlike virtual machines. Whether you are using Linux, OS X or Windows operating system, Docker has you covered. It is available as a free download being supported by open source project.


Understanding Docker

As Linux and Windows operating systems are designed for supporting major chunk of functionality for software containers, Docker brings about management and deployment of programs inside these containers. It helps bundle essential components and dependencies in a format that is easy to distribute.

This simplifies deployment of the containerized program on any Docker supported arbitrary system. In essence, Docker helps running of program irrespective of operating systems.

In a broader sense, the learning curve for Docker is less steep as compared with virtual machines besides its ability to run on either Linux or Windows operating systems. It is far easier to deploy applications within Docker containers as against virtual machine because it facilitates patching on Docker host instead of guest machines or host system.

There are fewer chances of system overhead because you do not need to run several Linux instances concurrently. Needless to mention, administrators are assured that there is no disruption to containers or host system by the processes inside containers.

Docker can be used for totally different purposes by different users. Organizations are able to establish faster delivery channels for offering software the latest features of software to end users. Docker is leveraged by developers who need to collaborate with other workers for elimination of issues such as ‘works on my machine’ Apps can be managed and run concurrently with help of Docker in isolated containers for enhancement of compute density by operators.

Docker From Developers’ Perspective

Developers can configure and setup environments for development for creating amazing software applications. Thanks to use of Docker, installation and configuration of complex databases is avoided by developers in addition to need to switch between language tool chain versions that suffer from incompatibility.

It is easy to push complexity into containers that are supported by Docker. Containers can thus be run and shared easily. You need not spend hours to explain procedures of setup and software installation while a new co-worker is being on-boarded. You can achieve greater simplicity by introducing Docker-file with a code that is being shipped.

Since dependencies are pulled as systematically packaged Docker images to help any individual build or debug the applications instantly by leveraging editor and Docker. With Docker’s built-in ability for easy to configure swarm clustering Developers can look forward to mimic production with lesser requirement of setup for testing and debugging apps without any hassles.

You can save significant amount of time that is needed to install and maintain software on developer machines as well as servers. It is far easier to test, build, and run apps that are complex and have features of multi-containers. Docker also facilitates building, testing, debugging, and deployment of container apps irrespective of operating systems used by servers including Linux and Windows and programming languages. There are no threats of conflicting versions or incompatibilities.


Benefits For IT Ops Teams

By streamlining delivery of software, Docker facilitates assured scalability and allows ease of development and deployment of bug fixes or additional features without any impediments. Docker helps teams of IT ops build, ship, test, and deliver apps, with greater security and dependability. Customers can enjoy seamless and quick availability of fixes and features with no downtime or hassles.

Maintenance of apps can be accelerated by ten times with ease of identification and resolution of issues while reducing IT operational expenses. Docker also enables quick rolling back without any disruptions. Developers can leverage Docker registries that are positioned in cloud for creation, distribution and management of Docker images. This also supports automatic synchronization of any changes into configuration or image updates.

Advantages of Docker for Enterprises

Docker is the backbone of contemporary application platform since it bridges Widows, Linux and IT. Whether the operation is on-premise or in cloud, Docker is capable of supporting conventional as well as micro-services environments. Docker is extensively used for building, networking, securing, and scheduling containers in addition to managing its journey from development to actual production. Enterprises can confidently and easily achieve their objectives of digitalization with cloud ready and agile apps with cost optimization.

By providing a uniform platform that offers an integrated framework for all types of apps whether these are micro-services or monoliths, Docker helps rapid scalability for accelerated innovation. Enterprises can look forward to fulfill customer needs more efficiently and quickly in terms of release or roll-back of new features.

Docker is regarded to provide a unified interface for reducing conflicts between dev and ops and facilitates their seamless collaboration. Thanks to development of other tools around Docker including Kubernetes, one can enjoy easy deployment of software containers within a given computing cluster.

Docker based containers have been transforming DevOps and is a vital addition to armamentarium. Apps can be easily run and tested within Docker environment and can be subsequently deployed in different environments including cloud or on-site irrespective of operating systems. Unlike Virtual Machines that support flexibility of working in diverse environments, Docker’s principal focus remains on applications as well as their dependencies.

Docker offers excellent ability to boost portability of cloud and helps deployment and running of applications in myriad of virtual environments. It packs applications into containers by bringing about isolation of dependencies of every application.
