Kubernetes (commonly stylized as k8s) is an open-source container-orchestration system for automating application deployment, scaling and management.
It is maintained by the Cloud Native Computing Foundation and considered de facto standard of container-orchestration application system.
It works with a range of container tools, including Docker.

The system requirements for deploying Kubernetes can vary depending on your specific use case, such as the expected workload, data volume, and the desired level of performance and availability. Recommended minimum system requirements include:
CPU: 2 or more cores
RAM: 4 GB or more
Disk: Sufficient storage for your containerized applications
Network: Fast and reliable network connectivity between nodes
Refer to the Kubernetes documentation for custom requirements and instructions.
Kubernetes is a powerful container orchestration platform that is widely used in various scenarios to manage, deploy, and scale containerized applications.
Here are some common use cases for Kubernetes: microservices architecture; multi-cloud and hybrid cloud deployments; continuous integration and continuous deployment (CI/CD); auto scaling and resource optimization; high availability and fault tolerance; stateful applications; edge computing; IoT (Internet of Things); big data and analytics; development and testing environments.
While Kubernetes is a dominant and widely adopted container orchestration platform, there are several alternative solutions that cater to different needs and preferences. Here are some popular alternatives to Kubernetes:
Docker Swarm, Amazon ECS (Elastic Container Service), Apache Mesos, OpenShift, Nomad, Rancher, Google Kubernetes Engine (GKE), Microsoft Azure Kubernetes Service (AKS), D2iQ (formerly Mesosphere), and K3s.
The key differentiators between Kubernetes and other container management platforms stem from its design philosophy, architecture, and specific features. They can include:
Kubernetes uses a declarative configuration where users define the desired state of their applications and infrastructure in YAML files. Kubernetes continuously reconciles the current state with the desired state, making automatic adjustments as needed.
Kubernetes offers high flexibility and extensibility through a well-defined API and a robust system of extensions. Custom Resource Definitions (CRDs) enable users to extend Kubernetes to support custom resources and controllers.
Kubernetes offers a comprehensive set of orchestration features, including automated load balancing, rolling updates, scaling, and self-healing capabilities. It supports complex deployment strategies and has advanced features for managing stateful applications.
Kubernetes has robust resource management capabilities, allowing for fine-grained control over CPU and memory allocation. It supports Horizontal Pod Autoscaling to dynamically adjust the number of pod replicas based on resource utilization.
Here are some reasons to consider Kamatera for your Kubernetes hosting:
Global Data Centers: Kamatera has a global network of data centers, allowing you to deploy Kubernetes clusters in geographically diverse locations. This can be beneficial for reducing latency and enhancing the availability of your applications.
Scalability: Kamatera’s infrastructure offers scalability, allowing you to easily scale your Kubernetes clusters based on demand. This is particularly important if your workloads experience varying levels of traffic.
