Launched in 2014, Kubernetes quickly gained popularity among software developers. According to a 2019 survey by the Cloud Native Computing Foundation (CNCF), about 78% of its respondents are using this platform in production, which sees a jump of around 20% from the previous year.
This follows the unabated growth of containerization. In recent years, developers and executives have trained their eyes on containers due to their usefulness. According to the most recent Container Adoption Survey conducted by Market Cube, 87% of respondents said they used container technologies. Although containerization proves useful, it requires that you have a system for managing multiple moving parts. This is where Kubernetes comes to the rescue.
What exactly is Kubernetes? How has Kubernetes evolved into one of the most useful platforms today?
Kubernetes, also called K8s, is open-source software for deploying cloud-native applications. The platform supports scaling and managing containerized apps. K8 serves as an orchestrator that manages workloads to ensure the whole app runs properly and schedules containers on a cluster.
Designed to support software development and operations, the Kubernetes platform‘s architecture and design are anchored on operations tasks and their performance. What’s peculiar about this platform is that it exclusively uses declarative constructs that define how an app is composed, how it interacts, and it is managed. With these properties, Kubernetes optimizes portability and operability in modern IT solutions. It also enables IT, developers, to easily incorporate GitOps workflows into the development process, thereby optimizing the speed and reliability of features.
What are the pros and cons of Kubernetes?
Pros of Kubernetes
Kubernetes owes its unprecedented growth to some of its powerful features. Here are the pros of the K8s platform.
Since Kubernetes can be hosted on a public cloud environment, it can be deployed quickly anywhere. By revamping the way apps are developed and deployed, K8s has enabled the teams to scale much faster than in the past.
Kubernetes has a vast ecosystem of useful tools that you can use. These open-source tools do not come with a proprietary or closed system, so you can freely use them with your K8s projects.
As a market leader in cloud-native computing, Kubernetes is a reputable system that you can depend on for application deployment, scaling, and management. The system also releases new updates and fixes bugs. Further boosting its credibility is the fact that it was originally designed and maintained by Google, before the management of the Cloud Native Computing Foundation.
The platform offers unmatched portability. Likewise, it guarantees simpler, faster deployment times. With this property, developers can utilize multiple cloud providers if necessary and scale up without the need to overhaul their infrastructure.
Kubernetes is available at both the infrastructure and application levels. With its additional storage layer, the platform guarantees that stateful workloads remain available. Furthermore, it enables developers to configure master components for multi-node replication, which guarantees higher availability.
With thousands of Github repositories and supported by a wide ecosystem of tools and developers, Kubernetes is a battle-tested and reliable platform that can help you with your container technology.
Cons of Kubernetes
Although Kubernetes is amazing, it is not a perfect system. In fact, transitioning to this system is fraught with challenges. Let’s check out some of its cons.
Steep learning curve
If you are new in software development, it might be best to look for other cloud-native ecosystems. Understanding the basic concepts of Kubernetes can be tough. Even experienced DevOps find a difficult time mastering advanced concepts. However, if you are really committed to learning the system, it’s realistic but may need time and effort.
Difficult to configure/install manually
K8 is comprised of several components that must be configured and installed individually to launch a cluster. The installation process involves other important pre- and post-installation tasks. Any mistake can cause it to fail. Fortunately, there are now cluster provisioning tools that can help simplify its installation.
Since Kubernetes is a hard-to-learn skill, experienced developers are limited, and hiring K8s talent is not cheap. Kubernetes experts are paid between $117,000 and $203,500 annually – a pay rate that might be unrealistic for small and medium enterprises.
The K8s development workflow is among the most complex. If you are not used to infrastructure technologies, you might find a hard time using the system, thus reducing productivity. In fact, you might not need to use this platform for a simple application. On the other hand, if used properly, this cloud-native system can boost productivity.
Deciding on whether to adopt Kubernetes or other platforms can be tough. You must consider your specific priorities and needs. Before taking the plunge, make sure you have considered the pros and cons of K8s so you won’t waste your time and investment.
