Docker & Kubernetes: Essential for Transformation

Recently more companies and enterprises have shifted toward cloud-native DevOps. In this journey, knowing how to use tools such as Docker and Kubernetes can provide an edge in digital transformation.

Following digital trends, companies have shifted paradigms and migrated their infrastructure and architecture to compete with cloud-native and data-driven technological trends.

Advanced containerization and orchestration have been eased with automation and cloud computing.

According to a 2019 survey by the Cloud Native Computing Foundation (CNCF), 84% of respondents run containers in production.

Other research shows container technologies including Kubernetes and Docker are likely to surpass other cloud-enabling technologies by the end of 2020, with a CAGR of 40%.

Why Docker and Kubernetes Are Essential

With rising interest and adoption of technologies, the projected market for technological containerization is expected to hit $4.3 billion in 2022, according to the research conducted by 451 Research.

Here is how Docker and Kubernetes simplify automated processes and increase efficiency.

Things to Know About Docker

Docker is an advanced containerization platform and a widely used open source project based on Linux containerization. More precisely, it is the container engine that uses Linux features such as control groups and namespaces to create containers on an operating system.

It has everything including code, system tools, runtime and operating system libraries. Docker guarantees to run the software regardless of its environment.

This platform is easy for people of diverse backgrounds to run their applications without any dependencies on OS issues.

Docker Gives You An Edge

Docker provides advanced technological assistance and system to developers and users so there are no dependencies in running the application.

Docker serves as a platform as a service, which is particularly designed to meet many challenges from DevOps trends.

Modern developers are all attracted to Docker because it can boost the containerization process. Using the Docker platform, users can speed up runtime in the operating system, application code, runtime, system tools, system libraries, etc.

Docker provides standards and developments that virtual machines are not able to:

  • Boot time is lowered to a few seconds.
  • Execution is done with the help of an execution engine instead of a hypervisor.
  • Deployment is easier than VMs. You only need one image that is accessible to all the operating systems.
  • Interference possibilities are higher because it has no provisions for isolation of systems.

Things to Know About Kubernetes

Kubernetes—K8s—has become the de facto technology in the automation journey of containerization and orchestration. It is a powerful tool that automates deployment and container management.

Using Kubernetes, you can put thousands of containers into action, from deployment to management to connection and upgrading.

Kubernetes provides what a whole team would not be capable of doing. According to the 2019 Container Adoption Survey, 65% of the developers and IT specialists are using container orchestration tools.

Kubernetes Helps in Transformation

Kubernetes is a tool that not only manages containers but also can:

  • Integrate and orchestrate the modular parts.
  • Make the container fault-tolerant.
  • Provide communication across the cluster.
  • Scale up or down according to need.

Containers are not able to do this all on their own. A tool such as Kubernetes gives professionals extension and superiority. The modern containerization and orchestration are based on these all.

How Do Docker and Kubernetes Work Together?

Docker and Kubernetes are designed to integrate and work together. The integration of both results in an organized DevOps system.

The integration is challenging but can be managed with the proper regulation of containers using Kubernetes to provide features such as load balancing, deployment, auto-scaling and health checks, which are crucial to the management of the container life cycle.

Docker, meanwhile, helps container creation—it is used for packaging and shipping the application.

Here’s a simplistic example: Docker acts like an airplane, whereas Kubernetes is the airport.

  • The combination of Docker and Kubernetes enables developers to pack and ship their app.
  • Using Kubernetes will help in deployment and scaling your app.
  • The process of containerization and orchestration is easier: on-time delivery is quick while achieving consistency and predictability.
  • Developers can spend more time on developing new features and fixing bugs.

Conclusion

Docker and Kubernetes together can improve productivity through automation, which enables teams to focus on more processes that are additive and integral to digital transformation.
