There is so much being said and written, by custom software companies about Docker and container virtualization. Docker needs no introduction. A highly popular technology now has a lot in store for the future too. What is it that makes it so popular? Why are developers building a higher fan base over it? What are the statistical figures that showcase the success of Docker?
This article highlights the fundamentals of Docker, container virtualization, continuous integration and its significance to custom software development services.
“Most organizations who have started using Docker have adapted to it within 1 month of usage”
“Docker usage is increasing by at least 30% every year”
As one of the popular open-source technologies around the globe, Docker has been an established name in the modern world of deployment container virtualization, facilitating OS-level virtualization and multiple containers executing on the unified server. It being lightweight, shares the operating systems of the hosts, does not run its own OS and hence looks like a hypervisor. It has a portable container that lets you host the application and allows deployment or relocation on any Linux server.
In the era of bespoke software development services offering an enriching experience, this innovative technology surely plays a big and important role.
The architectural part that looks after the management of containers and app deployment is the Docker engine. The Docker Hub maintains and manages the repository of the application.
Share, ship and run it anywhere is the key success mantra behind the latest advancement.
Launched by Solomon Hykes in France around March 2013, there have been varied versions, updates, and attachments that have been floated around each one having its own specific functionalities to offer. It started off as an internal project within dotCloud, a PaaS organization with contributions from other engineers. Little did they know soon it would be so popular and innovative in its success path. No wonder why there are a whole lot of organizations that are already implementing Docker successfully and leveraging its potential to the best.
There are many enterprises that are unleashing the potential of Docker and experiencing the worthiness of this innovative technology and the list is still increasing, never to look back.
Somewhere in June 2014, Docker had released its version 1.0 which got downloaded close to over 2.5 million times. And when you see today, the figure has extrapolated close to over 100 million. Doesn’t that simply show its success story?
The fundamental purpose of utilizing containers is to ensure all software components to execute perfectly while they are shutting between different phases such as development, testing, acceptance, and implementation. It is not necessary that containerization applies best within the software lifecycle phases. It also applies best when it comes to adopting cloud computing by moving from premise to Cloud or virtual machines. Here are some of the basic components of an ideal container.
In today’s IT glorified era, applications are being executed in containers instead of virtual machines. Considered as one of the most rapidly advancing technology, what lies at the core of containerization is Docker – the media through which users can seamlessly do the packing, distribution, and management of applications within containers. It facilitates the automatic deployment of apps within software containers which allow the users to chip in all needed parts like libraries as a unified pack. So, this makes it machine-independent and gives a sigh of relief to the developers in terms of no worry about which machine to use and whether it will be the same as the development one or not.
A quick and short way to deliver, iterations in a speedy manner, the risk at the minimum, value getting added like never, trustworthy software at your disposal – all these are key highlights of what you avail once you use Continuous Integration. This explains the importance of continuous integration in modern-day application development. To add to the success charts, containerization helps to enhance the entire process to the finest. Be it speed or the efficiency level, they are bound to get better with Docker.
Docker helps at its best in CI/CD implementation by helping developers build and test code, whatsoever may be the environment and grasp errors in no time. It saves big time on builds and process rearrangement. It offers seamless integration with popular source control management tools like GitHub and integration tools like Jenkins.
Docker has bee contributing to the development community in its pretty own ways and the results are positive and fruitful. The trends continuous and seems to be having a bright future.
Here are the key highlights of how bespoke software development is benefiting out of this technology:
With cloud computing being the trend today, Docker has proven its flexibility by being adopted by tech stalwarts like Amazon Web Services (AWS), Google Compute Platform (GCP), Microsoft Azure, OpenStack, Chef, Puppet, Ansible and many more.
Counting the environment and configuration parameters into the code is the highlight of Docker, which is why there is the least reliance on infrastructure needs and the solution can be executed against different platforms without any alterations.
The applications being executed on containers are totally separated and secluded from each other, offering you comprehensive control of the traffic flow and its monitoring. None of the containers can come to know about what is happening in the other. Containers are independent and have their own resource pool that manages all. This leads to a high level of security in all software phases. Isolating the application safeguards that the environment for each application has its own specific components with the original flavor.
The facilitation of letting multiple services execute concurrently increasing productivity with lower memory usage. This surely raises the efficiency level. Since the entire architecture is completely standardized, resources are fully in control of the available infrastructure, there is less time consumption and productive time available is on an increasing spree.
Docker is capable of decreasing deployment time to seconds. Since there is a container available for each procedure, there is no need for any operating system to boot every time. The cost factor involved reduces massively and deployment gets swifter and efficient.
For differently sized organizations, the core aim that they focus on is maximizing RoI and that is what Dockers help to do. It helps in lessening the cost factor and at the same time, an increase in profitability and productivity is achieved. Put together, it works as a highly cost-effective solution, offering stable returns over a longer period.
Docker offers diverse checkpoints at different levels, be it between containers or their versions. This aids enormously in fixing applications with ease and speed.
Because of both – Docker and container virtualization, the deployment procedure is now just a matter of a few seconds. This immutable nature of Docker has made it increasingly popular today.
what seems very clear is Docker has had a great start, is having a perfect present and is sure to have a bright future. With attributes like portability, flexibility, simplicity shining smart, there is no looking back for custom software companies now to leverage the potential of Docker.
