What is Kubernetes?

Kubernetes (K8s) is an open-source system for automating deployment, scaling, and management of containerized applications.
It groups containers that make up an application into logical units for easy management and discovery. Kubernetes builds upon 15 years of experience of running production workloads at Google, combined with best-of-breed ideas and practices from the community.

Kubernetes is highly valuable for its node-based setup, which allows for the running of multiple pods. This feature is essential for infrastructure automation and application deployment. Kubernetes also offers rollback control and auto-scaling capabilities, which are crucial for maintaining an application's availability even if nodes or pods go down. Additionally, Kubernetes supports load balancing to distribute traffic efficiently across multiple pods.

Some of their services could be improved. Kubernetes deploys containers as ports, and there are some services required to communicate between the ports because communication isn't built into the ports by default. I would also like to have Spark as another distributor service on Kubernetes. Security could be improved. It would be helpful if there were other security modules built into Kubernetes. Security has to be implemented properly.

The most valuable feature of Kubernetes is its support for load balancing. This is important because there are many users who use our application, and load balancing ensures smooth operation for all users. Additionally, Kubernetes contributes to cost efficiency by saving time in troubleshooting due to its self-healing mechanism. It also features predefined YML files that streamline deployments.

Room for Improvement

Kubernetes users express a need for features similar to vMotion for seamless workload transfers and a more user-friendly dashboard. Enhancements in network monitoring, GUI improvements, and simplified setup processes are desired. Users find the configuration complex and call for better integration, security features, and automation. Documentation and learning resources need to be clearer. Regular updates and more built-in functionalities could enhance performance while minimizing reliance on third-party tools. Better cost-effectiveness and ease of management are also sought.

"We faced a challenge while migrating and upgrading versions of Kubernetes. After the upgrade, some pods were not up as expected, leading to downtime."
"We faced a challenge while migrating and upgrading versions of Kubernetes."
"I would rate the stability as five out of ten. If any containers take more space, sometimes the cluster goes down."

ROI

Organizations see varied returns on investment from Kubernetes. Some note stability and enhanced market deployment speed as benefits, while others mention savings from infrastructure optimization by switching from VMs to containers. Some see faster application modernization and a streamlined deployment process, yet a few encounter high costs if scaling down. ROI percentages range from minimal to significant, depending on the transition stage and company objectives. Kubernetes aids improved services, though direct ROI estimation can be difficult.

Pricing

Kubernetes is open-source with no inherent licensing fees, under Apache license, making management layer access generally free unless utilizing AWS or other additional services, priced around $75 monthly. Cost-effectiveness varies with scale, favoring larger environments. Managed services add $100-$200 monthly. While infrastructure and storage fees apply, pricing depends largely on deployment specifics and cloud provider, like AWS, Google, or Azure. Its affordability appeals to enterprise users, but smaller entities may find it pricier when scaled down.

"Pricing isn't a major concern for us. Since we resell Kubernetes services and focus on providing support, integration, and education, we don't usually have pricing issues. Our customers are more concerned with getting the right support and services than the cost. So, the value we provide is more important than the actual pricing. Pricing might change in the future, but it’s not a big issue for us right now."
"It's an affordable solution"
"Microsoft provides reasonable costs for Kubernetes."

Popular Use Cases

Kubernetes is primarily used for container orchestration and deploying microservices, providing capabilities for managing complex infrastructures across cloud and on-premises environments. Users emphasize its role in enabling DevOps automation, facilitating application deployment, and ensuring scalability and fault tolerance. Kubernetes helps manage diverse applications, supports developers in transitioning from legacy systems to cloud-native architectures, and empowers IT teams to optimize resources with cost-effective solutions like AWS Spot Instances and Google Cloud's preemptible VMs.

Service and Support

Kubernetes customer service is mainly community-driven, with users relying on forums and documentation. Direct technical assistance varies by deployment type, with cloud vendors like Microsoft and AWS offering more structured support. Third-party companies like Red Hat and Rancher provide proprietary assistance. Users generally find community resources adequate, but mention the need for quicker, more reliable professional help. Complex issues often require escalating to external vendors, resulting in mixed satisfaction levels with responsiveness and effectiveness.

Deployment

Kubernetes initial setup complexity varies with environment and expertise. Cloud deployments are generally easier, while on-premises setups require more effort and knowledge. Managed services simplify the process. Experienced DevOps teams find it more straightforward, whereas beginners face challenges. Tools like Helm, Terraform, and CI/CD integrations aid deployment. Time for setup ranges from minutes to weeks depending on requirements. Expertise in Kubernetes and related technologies improves efficiency and reduces complexity in implementation and maintenance.

Scalability

Kubernetes is praised for its exceptional scalability, accommodating businesses from small to large with ease. By offering both vertical and horizontal scaling, it quickly adapts to changing needs. Users find it simple to scale, whether manually or automatically through integrations. While some encounter challenges in complex scenarios, the flexibility of scaling up or down as required makes Kubernetes a popular choice. Users appreciate its ability to maintain application availability seamlessly.

Stability

Kubernetes is known for its remarkable stability, supported by extensive community backing and enterprise usage. Reports show minimal issues, often related to external factors like cloud services or improper configuration. It operates without frequent glitches or crashes. While some managed services have faced specific challenges, the core platform remains robust. Users appreciate its maturity and reliability, attributing any disturbances to user error or external elements rather than any intrinsic deficiencies in Kubernetes itself.
