Kubernetes is designed as a single-tenant platform, which makes it hard to host multiple tenants in a single Kubernetes cluster. Kios is a lightweight, pluggable and customizable solution that adds multi-tenancy capabilities to any standard cluster.
Kubernetes is popularly known as K8s.
K8s is a production-grade open-source container orchestration tool developed by Google to help you manage containerized/dockerized applications.
It supports multiple deployment environments like On-premise, cloud, or virtual machines. k8s automates the deployment of your containerized images and helps the same to scale horizontally to support the high level of application availability
Kubernetes is a scalable and portable open-source platform for managing container workloads and services. Kubernetes facilitates both declarative configuration and automation in the process of managing large websites. It has a massive and constantly growing and evolving ecosystem that doesn’t show any signs of slowing down. Kubernetes offers services and tools that are widely available, and the platform also boasts a substantial online community for support.
Benefits of Kubernetes
Kubernetes boasts quite a lot of benefits for development:
● Scaling of horizontal infrastructure: Operations and actions performed at the individual server level for horizontal scaling are simple to execute with Kubernetes. ● Automatic scaling: Users and administrators can change and delete the number of running containers based on CPU usage and additional factors and metrics. ● Manual scaling: Users and administrators are able to scale running containers through the command line as well as in the interface. ● A replication controller: A replication controller makes sure that the cluster has the necessary equivalent pods in a running condition, and it also removes or adds any extra pods as necessary. ● Ample storage: Kubernetes shares data across many containers and stores data remotely in order to keep it connected until the user or administrator decides to delete it.
● Monitoring and logging: Kubernetes can offer reliable support for many versions of logging and monitoring when services are deployed within the cluster. Monitoring and logging are some of Kubernetes’ key features. ● Fantastic and superior speed: Kubernetes is the top-tier choice for continuously deploying specific features without any downtime whatsoever. It is capable of updating applications with constant uptime, making it a superior choice for high-speed management situations. ● Excellent declarative configuration: The Kubernetes system directly tells users and administrators the type of state it is in. This is done in order to make it clear where it should be to avoid errors. ● Scalability: Because of the unchangeable and declaratory nature of Kubernetes, it is simple and quick for the system to scale. This is done through a number of methods
Cons of Kubernetes
While Kubernetes is great, it does have some downfalls as well. Setup for Kubernetes is notoriously tricky because it uses varying setup processes for each operating system, which adds complexity to the setup and management process. While there is the benefit of easy-to-find online resources for Kubernetes users, it is still very challenging to build custom environments without a team of Kubernetes specialists and developers.
Migration is also somewhat complicated. If an application is clustered or stateless in Kubernetes, it will generate extra pods that will not be properly configured, which results in a total rework of the system configuration. Kubernetes is also not very compatible with many of the existing Docker CLI and Compose tools.
