How Kubernetes has risen to be the operating system of the cloud?

HomeResourcesBlogHow Kubernetes has risen to be the operating system of the cloud?
March 16, 2022 | Kubernetes
Read Time: 10:00

New technologies are developing and reshaping the IT industry today. Companies are evaluating their conventional approaches to completing work and implementing new ones. We are presently in the era of Cloud-Native apps. The introduction of microservices and the exponential expansion in application size profoundly change current software development and deployment. While this transition is most visible in cloud-born apps, practically every application nowadays is distributed and requires auto-scaling, auto-failover, and redundancy.

The rise of contemporary software delivery is influencing how software is supplied — both by those who supply a SaaS-based application that’s also remotely controlled through the internet and by conventional software suppliers who ship software that must be installed locally.

As this transition took place, the rise of Kubernetes occurred, which became essential to cloud-native computing because of its open-source characteristics.

Kubernetes Applications – On-Premises

Applications can either be supplied and used as a SaaS solution or as a local installation — this applies to both old 3-tier apps or desktop services as well as modern container-based apps.

We’ve seen many businesses use Kubernetes in several intriguing ways since the availability of a Managed Kubernetes solution. From mobile apps & video processing to Artificial Intelligence. While some of these businesses operate their Kubernetes architecture in the public cloud, many major firms also have Kubernetes-based apps for internal usage that run on local, on-premises hardware.

  • SaaS Providers – Going On-Premises

    Some SaaS suppliers provide products utilized by major enterprise development & operations teams.  As their client base expands to include Fortune 500 organizations & government agencies, the need to access the solution as a private SaaS solution, placed behind the firewall and administered internally, frequently emerges.

    Because many SaaS businesses are already using Kubernetes as the backend for their apps, it is simpler to leverage the same technology to operate their on-prem version.

  • Traditional Vendors – Going Cloud

    These vendors didn’t usually begin in the cloud & have been most successful in offering clients — notably large corporations —software installed on local PCs or on-prem data centers. They are currently attempting to broaden their market possibility by delivering the software as a SaaS product. Many of them are now looking to containers & Kubernetes as the core platform to modernize and cloudify existing offerings, making them “cloud-native.”  This, in turn, pushes them to seek Kubernetes offerings across various infrastructure – so that they may continue to build and distribute their product as a SaaS service and a local installation.

Kubernetes as an Operating System

Kubernetes is a relatively unknown technology. People like Sarah Wells, The Financial Times’ technical director for Operations & Reliability, see the spectacular rise as proof that the technology is “crossing the barrier” and reaching the early adopters.

The ability of Kubernetes to assist those whose job s to ensure that applications are smoothly deployed and run on-premises & in the cloud is a fundamental driver of its growth. Kubernetes is transitioning from basic, stateless apps to complex data-driven apps, and data platform vendors are taking notice.

Kubernetes has evolved as the preferred platform for building cloud-native apps. In essence, Kubernetes is evolving as an OS (operating system) – not in the traditional sense, but in the setting of a decentralized, cloud-native application.

It’s simple to understand why. Kubernetes provides many of the functionalities required to execute a cloud-native application:

  • High Availability: If a service instance fails, another one starts automatically.
  • Granular, limitless, scalability: A set of services operated behind a load-balancer, allowing each service to be scaled independently.
  • Rolling Upgrade: With rolling upgrade & rollback, you may upgrade one service independent of the others.Discovery
  • Discovery: Other services can be discovered using name service.
  • Portability: Kubernetes-based apps are portable throughout any environment or infrastructure provider that leverages Kubernetes because of the containers and the availability of multiple ‘Kubernetes-as-a-Service’ platforms.

 

Read a Blog post: Kubernetes: A Critical Part of Modern Enterprise IT Mix

How Kubernetes has risen to be the operating system of the cloud

 

While developers are obviously interested in these features, it is clear how important they are – notably the final point – to IT Operations.

You’d need to restrict your software/management variants to accelerate development, simplify upgrades & continuing operations, and reduce expenses. To achieve success, you must first establish the consistency & compatibility of the application code & management procedures across various types of infrastructure. As a result, regardless of where the app runs – private cloud, public cloud, or edge appliances – it is always built, deployed, and administered in the same manner.

In the end, you require techniques to:

  • Ensure integrity across infrastructure: This involves using a single API to build and manage clusters across various infrastructure, including cloud providers.
  • Getting the required control: You must be capable of integrating with the operations & tools of your choice, whether it’s a storage provider, network, or just utilizing SAML2 to authenticate.
  • Service Management: Focus should be on the application, not on infrastructure management, so select a solution that maintains the cluster’s footprint throughout multiple infrastructures, including version updates, patches, optimization, and more.
  • Un-managed: Finally, to successfully deliver software to your clients, choose a solution that allows you to OEM the product so it may be supplied as a self-contained, boxed platform on an ecosystem or edge appliance that may not have internet access.

What’s ahead for Kubernetes?

Despite its unusual origin, Kubernetes has gained in popularity. We’ve seen a lot more maturity & support for stateful workloads over the years and tremendous ecosystem support in this regard, with greater security and ongoing simplicity. And as  it’s evolves, we are seeing many more businesses adopt it.

As Kubernetes’ multi-cluster functionality develops, it may start recognizing such clusters as a cohesive group and allow clusters to be controlled collectively. This may result in a lot of global-scale ecosystem effort, latency reduction, and keeping up with security & recovery. And this might need the development of new services to allow clusters to pool resources.

Expect to see increased automation. This may be pushed mainly by host cloud providers and the other providers in the ecosystem. Cloud providers may inject even more automation into the system as feasible as Kubernetes supports additional stateful apps and continues to broaden its cluster management. In addition, ecosystem startups may contribute technologies to manage app resources effectively.

Finally, as these capabilities evolve, we may anticipate improved support for data-intensive tasks like artificial intelligence (AI), machine learning, & inference. Because large workloads use so many resources, scheduling them becomes more difficult. As performance management grows increasingly complicated, it must develop. To be realistic, many of the team’s technologies on the back burner early on, such as Docker Swarm or Mesos, may start to make their way into the Kubernetes landscape.
