Docker for growing Businesses- Why is Docker so popular among businesses?
Any business venture on earth runs on three key words - easy to move, quick to respond and versatility of the product . It is true for both ends , the buyers and the producers. This credo if three words leads the venture to its desired profitability . This is also no less true in the case of the soaring popularity of Docker among the business class. Being launched in 2013, Docker empire has spreaded its influence across the spectrum , from big tech companies to promising start-ups.
Not only Linux platforms such as Red Hat and Canonical have embraced Docker , but also the proprietary software companies like Oracle and Microsoft have also subscribed to this open- source container technology. Docker has managed to win the hearts of almost all IT and cloud companies .
Now, let's introspect the reasons behind Docker's burgeoning popularity.
1. The experts in the field explains VM hypervisors, such as Hyper-V, KVM, and Xen, thrive on emulating virtual hardware. This indicates that they're fat in terms of system requirements.
On the contrary, Containers are at ease at shared operating systems. This leads them to an enhanced efficiency than hypervisors so far the exploitation of system resource is concerned. Containers get along with a single Linux instance ignoring virtualizing hardware. This elucidates the fact that one can leave behind the useless 99.9 percent VM junk after assuring a small, neat capsule in possession, containing the application.
2. With a perfectly tuned container system, four-to-six times the number of server application instances find themselves operable while using Xen or KVM VMs on the same hardware.
3. The platform offers an intersectional interactive approach among the containers. They are engaged into a Continuous Integration/Continuous Deployment (CI/CD). This DevOps methodology envisages the developers to integrate their code into a shared repository early and often, and then asks them to deploy the code quickly.
4. Docker's lightweight, portable, self-sufficient containers empower developers to pack, ship, and run any application easily .
5. Containers' hidebound quality to isolate code into a single container, enables the developer to modify and update the program easily . Here Jenkins, an open-source CI/CD program plays a pivotal role to automate the delivery of new software in containers.
6. It can be appropriated into most DevOps applications like Puppet, Chef, Vagrant, and Ansible. It can also be used to manage development environments. Docker containers are easily deployable in cloud.
7. It is possible to set up local development environments that are exactly like a live server by using Docker. It helps to run multiple development environments from the same host .This allows the users to work on the same project with the exact same settings, regardless of the local host environment.
Conclusion
A 2016 Puppet survey shows ITcompanies with a strong DevOps workflow used the software 200 times more frequently than others. The recovery rate is 24 times faster and three times lower rates of chance of failure. It requires an overall 50 percent less time in addressing security issues and 22 percent less in unplanned works.
