• Professional: $2,995 per year.
• Enterprise: Contact sales for pricing.

The Home and Student plan is restricted to non-commercial use. It includes 15 nodes and community support. The Starter plan includes five nodes, community support, and is suitable for commercial use. Professional offers scalability by adding nodes, 9×5 support, onboarding assistance, and a customer success agent. Enterprise offers scalability and onboarding assistance, too, plus an assigned success engineer, priority support, and custom MSSA.

Kubernetes

Kubernetes (also known as K8s) is an open-source orchestration and DevOps tool that helps developers automate containerized applications’ deployment, management, and scaling. It is ideal for organizations looking to efficiently manage distributed and complex applications at scale.

Features of Kubernetes

Some of Kubernetes top features include:

• Automated rollouts and rollbacks
• Storage orchestration
• Service discovery and load balancing
• Self-healing
• Automatic bin packing
• Batch execution
• Secret and configuration management
• Horizontal scaling

Kubernetes automatically rolls out changes to your application/configuration while monitoring health to ensure all instances are not simultaneously killed. If a mistake occurs, Kubernetes rolls back the change for you. Whether from a public cloud provider, local storage, network storage, etc., Kubernetes automatically mounts your desired storage system.

The container management tool eliminates the need to modify applications using an unknown service discovery mechanism by giving Pods their own IPs and each Pod set a single DNS name while balancing loads across them. And should any containers fail, nodes die, etc., Kubernetes self-heals.

Automatic bin packing is another Kubernetes highlight that saves resources and maintains availability, and it can manage batch and CI workloads, plus replace failed containers if needed.

There is no need to rebuild your image or expose secrets in your stack configuration thanks to Kubernetes’ secret and configuration management capabilities, and you can scale applications up and down automatically, via a UI, or with simple commands.

Pros of Kubernetes

Kubernetes’ pros include:

• Automation
• Multi-cloud deployments
• Flexibility
• High availability

Kubernetes makes it easier for developers to update and maintain large, complex applications by automating several tasks involved in the deployment and management of containers.

The programmer tool is ideal for multi-cloud deployments since it deploys on multiple cloud platforms and is flexible since it works with various containerization technologies beyond Docker. Another plus of the DevOps tool is that it can run thousands of containers while maintaining high availability.

Cons of Kubernetes

Kubernetes’ cons include:

• Maintenance and management requirements
• Not ideal for simpler uses
• Steep learning curve

Teams looking to run Kubernetes for large-scale projects will require added personnel and resources for proper maintenance and management. Kubernetes may seem excessive for simple applications/services and small workloads, and those new to distributed systems and containerization will face a steep learning curve and may need extra time to get used to the DevOps tool.

Pricing of Kubernetes

Kubernetes is an open-source developer tool that you can download and install for free without worrying about licensing costs. While Kubernetes itself is free, you can incur costs when using the tool for infrastructure (servers or cloud providers), operations (updates, monitoring, troubleshooting, etc.), third-party tools, and more.

Docker

Docker is a popular open-source containerization platform and DevOps tool. It helps developers automate the deployment, management, and scaling of applications within containers and is known for its scalability, portability, and isolation.

Features of Docker

Some of Docker’s most noteworthy features include:

• Containerization
• Consistent environment
• Scalability
• Portability
• Isolation
• Security
• Docker Compose
• Docker Swarm
• Docker Hub

Docker containers are standalone, lightweight, and executable software packages that provide developers with everything they need to run applications, including code, system tools/libraries, runtime, settings, etc. Developers can improve application quality and minimize errors by using Docker’s consistent development and testing environment, plus they can scale up and down with ease for applications dealing with fluctuating workloads.

Docker containers are easier to manage and are more lightweight than virtual machines. Their portability makes application deployment across varying environments a cinch. And since they are isolated, Docker’s containers provide a barrier between applications and the operating system.

Developers can increase container security via features like network isolation and image signing. The programmer tool also features Docker Compose for simplifying complex application deployment, Docker Swarm for offering high availability and scaling applications, and Docker Hub for storing and sharing Docker images.

Pros of Docker

Docker’s strengths include:

• Docker Desktop
• Consistent environment
• Enhances scalability and security
• Simplified application packaging and deployment

The Docker desktop provides a seamless experience for creating and running containers by bundling the Docker engine and runtime utilities. The DevOps tool gives developers a consistent environment for application development and testing regardless of underlying infrastructure, and its containerization technology makes it easier to enhance scalability and security. Another Docker pro is how it provides a standardized method for building, managing, and running containers, which simplifies application packaging and deployment.

Cons of Docker

Docker’s weaknesses include:

• Complex setup and management
• Resource usage
• Native orchestration
• Application monitoring

Setting up and managing Docker for complex, large deployments can be a chore. If containers are not set up and managed properly, this could cause issues with instability and resource contention. Running Docker requires additional resources, which can negatively impact system performance. Other knocks on the programmer tool include the lack of native orchestration and out-of-the-box application monitoring.

Pricing of Docker

Docker’s four pricing plans are as follows:

• Personal: Free.
• Pro: $5 per month.
• Team: $9 per user, per month.
• Business: $24 per user, per month.
