IT infrastructure has changed dramatically during the previous two decades. Virtualization introduced hardware abstraction, private clouds provided cost-effective flexibility, and containers continued to add to the stack of ideal solutions. Kubernetes has dominated the technology landscape for the past few years.
Kubernetes isn’t a brand-new technology anymore. Even though it has a long way to go, it has been warmly welcomed during the previous two to three years. As per a study by Gartner, by the end of 2022, over 75% of worldwide enterprises will be operating containerized apps in production, up from less than 30% currently.
With the efficiency and convenience that containers bring, Kubernetes is seeing a rise in popularity. However, with the benefits comes a trail of Kubernetes fallacies. Let’s debunk some frequent Kubernetes misconceptions.
Only the public cloud uses Kubernetes
Kubernetes is frequently referred to as a cloud-native technology, and for a good reason. Kubernetes is cloud-native, which means that it was built to make use of cloud computing architecture while also supporting distributed application size and resiliency.
Kubernetes can operate on various platforms, including a personal computer, virtual machine, bare-metal server rack, public/private cloud environment, and so on.
Enterprises can bring together groups of servers running Linux containers, and Kubernetes makes managing those clusters simple and efficient. These clusters can span public, private, and hybrid clouds and span several hosts.
Kubernetes is safe and secure
One thing that everyone should be aware of is that nothing is entirely safe. Everyone has heard that the cloud is safe, that utilizing containers is safe, and that banking is secure. It is not. It’s as safe as the companies make it. There will be a new vulnerability tomorrow, but until then, the environment is quite secure.
Kubernetes is in a similar situation. The surface area for exposure is decreased according to Kubernetes’ architecture. Firms can now protect their most valuable assets from the outside world.
Manual mistakes are the source of many security breaches. Firms must design a method to guarantee that everything is kept safe. It’s the same with Kubernetes. Organizations should keep their eyes and ears alert for potential threats. Furthermore, things are only safe until a vulnerability is discovered and exploited. Kubernetes and containers are no exception.
Businesses must use Kubernetes to operate everything
Containers are an effective way of delivering and expanding a unit of work, and they may coexist with other technologies in a hybrid stack. Kubernetes adoption does not have to be an all-or-nothing approach. When migrating to Kubernetes, architects might employ a phased or hybrid strategy.
It’s completely acceptable to have a hybrid architecture that includes classic monolithic services, PaaS services, and containerized services that operate within or outside Kubernetes. Firms can utilize Kubernetes for containerized services while maintaining their existing infrastructure. This might be the final destination or a stage on the way to a completely containerized application.
Kubernetes is a fully functional system
In actuality, Kubernetes isn’t even close to being a complete product. Kubernetes is an open-source project rather than a product. New users should know one key reality: the Kubernetes ecosystem moves at a breakneck pace. It’s even been labeled the fastest-moving open source project ever.
A fast-paced, highly engaged community develops Kubernetes and associated projects. As the world evolves, so must the way businesses see and build things. It’s all for the better, but there’s still a lot to keep track of.
