What is Containerization?
Let us take it from the top so that every one of our readers is able to understand it.
Containerization is the technology of packaging software and its dependencies in a single container or a self-containment unit.
It involves,
- Packaging i.e., wrapping up an application and its linked features in a single and lightweight package.
- Isolation i.e., each container works in isolation, which ensures that it is not impacted by any changes to the other containers.
- Portability is maximum, as these containers can be moved on demand.
- Automation is easy via containerization because now the focus can be on a single application or function in software.
Containerization is paving the way to Microservices, Cloud-Native Applications, Edge Computing, and more while delivering better security, resource utilization, time-to-market, flexibility, scalability and maintenance.
Now, let us get to the two contenders that will be entering a virtual ring for us.
What is Kubernetes?
Kubernetes is the container management system that was developed by Google Go in June 2014.
Via it, you can manage a container in cloud, virtual and physical environments.
Kubernetes is quite flexible, be it the delivery of a complex app or running 100 to 1000 services.
What are the key features of Kubernetes?
Fig 3: A graphical representation of the key features of Kubernetes.
The key features of Kubernetes are,
Ø Works Everywhere
Be it a public or hybrid cloud, Kubernetes’ open-source feature gives you the freedom to explore.
Ø Automation
Kubernetes can control your software’s containers automatically as per your directions.
Ø Interaction
It can easily manage multiple clusters while facilitating vertical and horizontal scaling.
Ø Self-monitoring
It can self-monitor the health of all the nodes & containers under its control and relay information accordingly.
Ø Add-Ons
Be it secure networking, storage or other container management features, Kubernetes offers a lot.
Kubernetes: Advantages vs Disadvantages
Here is a tabular comparison to help relate with Kubernetes.
| Advantages | Disadvantages |
| Automated container scheduling | Steep learning curve |
| Service discovery for the best interoperability | Install & Configuration issues |
| Self-Healing for crashed containers | No high availability by default |
| Rolling Upgrades for old containers | Compatibility issues with Docker |
Use cases of Kubernetes
Finally, we bring the use cases of Kubernetes,
- Microservices Architecture is aptly managed by Kubernetes.
- CI/CD or continuous improvement/continuous development methodology, works best with Kubernetes.
- Hybrid & Multi-Cloud deployments are made easy using Kubernetes.
- Kubernetes dynamic resource optimization allows for a balanced workload to reduce hardware costs.
We are sure that this much information is enough to make sense of the final comparison.
What is Docker?
Docker is another platform that can be used for containerization of the software.
It was launched in March 2013 and is simplifying DevOps by allowing developers to create templates via images to craft a lightweight virtual machine called a container.
What are the key features of Docker?
Fig 4: A graphical representation of the key features of Docker.
The key features of Docker are as follows:
- Easy Configuration via easy-to-deploy code in varied environments.
- Docker Swarm helps in developing software which can have various integrations in the frontend.
- Secure via swarm security and allowing only access-based entry.
- Service helps in facilitating various functions in a cluster.
- Better Productivity due to easy implementation and deployment.
Docker: Advantages vs Disadvantages
We share a tabular comparison of Docker’s advantages and disadvantages below.
| Advantages | Disadvantages |
| Build an App only Once | Missing features like self-registration, self-inspection and more. |
| Test environment and Work environment are the same (container). | Container data backup is not automated. |
| Portable on various platforms like VirtualBox, Google Cloud, Amazon EC2 and more | Doesn’t support features needed by a complex graphic app. |
| Version Control feature | Can deliver efficiency for simple apps only. |
Use Cases of Docker
Docker can be used for,
- Microservices
- Containers
- DevOps Adoption
- Software Testing
- Legacy App Migration
Are you ready for the finale or the comparison between the two?
Kubernetes vs Docker: The Difference
Now it is time to lift the curtains and let these two contenders prove their worth in terms of containerization.
| Feature | Kubernetes | Docker |
| Type | Open-source platform for containerization | Tool for automated deployment of lightweight applications |
| Usage | Most commonly used with Docker | To run multiple containers on the same hardware without the use of Virtual machines |
| App Deployment | Deployment as a combination of pods and services. | Deployment in the form of services. |
| Auto-scaling | Supported in clusters | Not supported |
| Health Checks | Two types -> Liveness & Readiness | Limited to the service |
| Configuration | Hard to setup & configure | Easy setup and installation |
| Documentation | Extensive but lesser than Docker | Quite vast |
| Used by | Azure, Intel, Shopify, Evernote and more | Google, ADP, Amazon, VISA and more. |

Kubernetes vs Docker: Operations
By understanding the operational features of both, you can be the best judge when it comes to choosing one of them.
- Kubernetes manages clusters of compute operations that run in logical groups known as pods while allowing automation.
- Docker can create, operate and find container images using its commands like Docker Build, Docker Compose and Docker Hub, respectively.
Result
Choose Kubernetes for automation and better functionalities.
Kubernetes vs Docker: Core Technology
By knowing about the core technologies of the two, your business can align it perfectly with the existing system.
- Kubernetes uses control panel software which helps in deciding which pod to run by managing traffic around it.
- Docker uses Docker Engine, which provides the APIs that software can use to run, interact and more.
Result
Choose that amongst Kubernetes vs Docker which suits your needs.
With the comparison complete, it is time to know how and which one to use for your business endeavour.
Kubernetes vs Docker: Can they be used together?
Well, in fact, Kubernetes and Docker should be used together.
Just because they both offer containerization, they are often confused as competitors.
Docker can be used to deploy applications inside portable and lightweight containers. While Kubernetes can be used to manage already created containers.
Thus, various organizations use Docker to create and manage containers while they use Kubernetes for the overall orchestration.
In short, use both of them by leveraging the best features of the two and get the best software creation, deployment and management.
Kubernetes vs Docker: What are the benefits of their integration?
If you need more convincing, we got some benefits for the integration of Docker and Kubernetes that will woo you.
