The Kubernetes master is the primary control unit for the cluster. Kubernetes was developed by and used and maintained by Google which not only gives it instant credibility, but can be trusted to fix bugs and release new features on a regular basis. Proven, and Battle TestedĪ huge ecosystem of developers and tools with 5,608 GitHub repositories and counting means that you won’t be forging ahead into new territory without help. Since Kubernetes is open source, you can take advantage of the vast ecosystem of other open source tools designed specifically to work with Kubernetes without the lock-in of a closed/proprietary system. In addition to this, the master components of a cluster can be configured for multi-node replication (multi-master) and this also ensures a higher availability. Adding a reliable storage layer to Kubernetes ensures that stateful workloads are highly available.
Kubernetes addresses high availability at both the application and the infrastructure level. And because Kubernetes has fundamentally changed the way development and deployments are made, teams can also scale much faster than they could in the past. With Kubernetes' ability to run containers on one or more public cloud environments, in virtual machines, or on bare metal means that it can be deployed almost anywhere. This means that companies can take advantage of multiple cloud providers if needed and can grow rapidly without having to re-architect their infrastructure. Kubernetes offers portability, and faster, simpler deployment times. K8s became popular for the following key reasons: Portability Recently they have started to standardize around Kubernetes as a single target architecture, creating opportunities to align DevOps practices around a specific deployment target.” Kubernetes Leads the PackĪs the first Cloud Native Cloud Foundation (CNCF) project, Kubernetes is the fastest growing project in the history of Open Source software.
#WHAT IS KUBERNETES FOR SOFTWARE#
“Container-based infrastructures and microservices offer a frontier for software deployment, creating significant potential for enterprises looking to deliver massively scalable, flexible, and distributed applications. It also allows developers to easily adopt GitOps workflows into their development pipelines which increases the velocity and reliability of feature deployments.
This enables a significant increase in the operability and portability of modern software systems. Almost everything in Kubernetes uses declarative constructs that describe how applications are composed, how they interact and how they are managed. As an orchestrator, Kubernetes handles the work of scheduling containers on a cluster and also manages the workloads to ensure they run as you intended.īecause Kubernetes was designed from the beginning with the idea of software development and operations working together, operations tasks and how they get performed are an integral component of the Kubernetes architecture and design. So what exactly is Kubernetes? Kubernetes (also known as K8s) is open source software for deploying, scaling and managing containerized applications.
#WHAT IS KUBERNETES FOR HOW TO#
While Kubernetes has advanced capabilities, all that power comes with a price jumping into the cockpit of a state-of-the-art jet puts a lot of power under you, but how to actually fly the thing is not obvious.With Kubernetes you can deploy cloud-native applications anywhere and manage them all exactly the same. But this approach may not be right for every organization. The primary early adopters of Kubernetes have been sophisticated, tribal sets of developers from larger scale organizations with a do-it-yourself culture and strong independent developer teams with the skills to “roll their own” Kubernetes.Īs the mainstream begins to look at adopting Kubernetes internally, this approach is often what is referenced in the broader community today.
However, Kubernetes’ complexity is overwhelming for a lot of people jumping in for the first time. Kubernetes has a strong ecosystem around Container Networking Interface (CNI) and Container Storage Interface (CSI) and inbuilt logging and monitoring tools.
Kubernetes can scale up and scale down based on traffic and server load automatically. Kubernetes clustering has very high fault tolerance built-in, allowing for extremely large scale operations. For teams that have the skills and knowledge to get the most of it, Kubernetes delivers: Kubernetes has many powerful and advanced capabilities.
