Kubernetes: How is K8s Transforming Container Management?

Since the emergence of K8s or Kubernetes in the spotlight in 2014, it has been transforming container management by continuing to impact the way companies are managing containers via software. Giant commercial players have already backed it, affecting commercial open source systems and causing a ripple effect in the industry.

What is Kubernetes?

Kubernetes began as a simple open-source commit that was created to facilitate container support. Soon, the world was delighted to see Kubernetes be the core of the operation and creation of modern software, playing a vital role in the global economy.

The success of Kubernetes in business transitions presented a considerable impact. Business transitions presented worldwide implications in an appropriate manner. All thanks to the unprecedented cooperation that can be easily afforded by the open-source software movement.

Just like any other relevant technology, Kubernetes has become more than only itself. It has positively affected it arises the ecosystem. It has positively changed how work is done, how software is deployed at scale, and how large scale corporations are engaged with massive open-source projects.

To dive into the basics and advanced topics of Kubernetes, Cloud Academy offers a learning path designed to help you prepare you for the Certified Kubernetes Application Developer (CKAD) exam. It includes a combination of courses covering each exam domain, a series of hands-on labs to build first-hand Kubernetes experience working directly in a live cloud environment, and exams to test your knowledge along the way.

Container Orchestration & Management

Modern applications, including large ones, are no longer monoliths. Instead, they consist of several loosely coupled elements that are in need of work in tandem with communication. These parameters may include ETL pipelines, ingesting social media data service streams, and APIs that are designed to serve analytical dashboards.

Additionally, these services can take place in separate containers that enable developers to deploy, release, and scale independently. This leads to a significant separation of concerns, which allows efficient resource allocation and a faster cycle for critical elements as well. It allows developers to solve several challenges that may arise from these types of architectures, including rolling updates, replication of containers, automated deployment, secure communication between vessels, and high availability when containers fail.

How is K8s Transforming Container Management?

As per the experts, Kubernetes is a modified form of Docker to put them to a better outlook. Kubernetes has provided an infrastructure that has offered developers to be more stateless, scalable, self-healing, and flexible. Kubernetes lets you scale up specific services that were previously broken into microservices.

Additionally, it enables the user’s ability to specify instance quantities and qualities. Kubernetes made that happen and restarts as per need. Google open-sourced the Kubernetes project and has brought 15 years of knowledge to process with an edge speed. Soon, we are supposed to see the adoption of every possible cloud environment to support Kubernetes. Developers can scale up to get real scale production workloads along with fault tolerance that may not have been possible otherwise.

Below are some contributing benefits of Kubernetes that has proven to change the management and orchestration of containers.

1. Automatic Bin-Packing

The technology of Kubernetes schedules containers and packages your application automatically based upon their available resources and requirements. Also, they don’t sacrifice availability. Kubernetes balances between best efforts and critical workloads to assure complete utilization and save unused resources.

2. Service Discovery & Load Balancing

With Kubernetes, you don’t need to worry about communication and networking to modify your application. Moreover, you don’t need to adjust your applications to use with an unknown discovery mechanism for services. The reason is, Kubernetes assigns containers their own IP addresses along with a single DNS name to an entire set. This can help to load-balanced traffic across the clusters.

3. Storage Orchestration

With Kubernetes, you can mount the automatic storage system of your choice. Also, it opts you for both local storage services, a public cloud provider including AWS and GCP, or even a shared network storage system including Gluster, Ceph, iSCSI NFS, Cinder, or Flocker.

4. Self-Healing

Users, most like the feature of Kubernetes. It is a kind of a personal favorite for most of them. Kubernetes are designed in a way that they can restart automatically when containers fail during execution. They are programmed to discard those containers that don’t comply with user-defined health check quality standards and don’t advertise them until they are fit for use. Moreover, if any nodes die itself, it reschedules and replaces those failed containers with other available nodes. 

5. Secret & Configuration Management

Kubernetes is an ideal check that can deploy and update application configuration and secrets without exposing them and rebuilding your image in your stack configuration. Just like the applications of dissertation writing service, cloud computing can leverage the phenomenon of privacy and configuration management with authentication by Kubernetes.   

6. Batch Execution

With successful executions of management services, Kubernetes is an ideal option to manage CI workloads and batch executions; although, it replaces failed containers quickly as per the desire of client and company. 

7. Horizontal Scaling

The best thing about Kubernetes is that it needs only a single command to scale up containers or to scale them down while utilizing CLI. Otherwise, scaling can also be done via UI facilitated by Kubernetes Dashboard.  

8. Automatic Rollbacks & Rollouts

Kubernetes is successful in rolling out updates and modifications to your application with configuration. It ensures that all instances should work in different aspects. Even if anything goes wrong, it is are efficient enough to roll back the change for you. 

9. User Experience

Kubernetes provides users with a “wow” in terms of experience. There is a massive community formed around creating and advancing projects concerning facilitating the vice of clients. Google has already invested a lot of money launching the open-source product just to comply with user needs in collaboration with CNCF to make an entirely new ecosystem for voice raised concerns. 

Tackling Challenges

Despite the above benefits that Kubernetes offers for the management and orchestration of containers, it has been succeeding in addressing the current challenges of the industry below.

1. Manage State

Although the managing state is not a direct application for container management, it is an essential contributing one. State-full applications, including caches, databases, and message queues, face challenges; most of them are due to probability. The state of shipping has to be maintained in every situation of container processing, including starting, stopping, and replicating. The term is challenging to be kept in a multi-cloud and distributed environments.

Kubernetes are solving these issues with maintaining persistent volumes and state-full sets. Practically, all of these options are great to cover any unexpected situations. However, they are still many of the issues that they are unable to tackle, of course, for the time being. Fortunately, the sheer complexity of orchestration and management of containers often outweighs the advantages in production scenarios handled well by Kubernetes.

2. Security

Getting goods secure is a huge deal in the corporate world. Regardless of the many advantages offered by containers, they do not have the same level of multi-tenancy and isolation as provided by virtual machines. That is why enterprises are more prone towards making containers more secure and safe to ship. Google’s open-source g-Visor is designed to bring better isolation to boxes that nicely integrate with Kubernetes. 

3. HPC (high-performance computing)

Enterprise data centers often run companies dealing in container business for a wide range of workloads on a variety of servers. They may include GPU machines that are created to run intensive compute operations of AL/MI pipelines. Kubernetes use tolerations and taints to address these issues. It makes sure that all pods are scheduled into adequate nodes, and it helps workloads to run on a well-crafted infrastructure that is essential to be used in separate cases, including running workload on machines having DMZ systems as well. 

4. Multi-Cloud Deployment

The primary requirement for the modern industry is to enable multi-cloud deployment to prevent lock-in. Undoubtedly, it possesses a significant technical challenge that is difficult to be handled by a simple deployment tool. This requires a combination of architectural and technological approaches. That is why we have seen significant growth with Kubernetes incorporate offerings including Docker, OpenShift, and Google’s Anthos. 

Challenges vs. Needs for Kubernetes

Kubernetes is one of the topmost open-source projects under the Cloud Native Computing Foundation (CNCF), operating as an umbrella organization. Kubernetes is backed by some of the largest enterprises in the market, including Microsoft, Apple, Amazon, SAP, Google, and Oracle. 

The innovation results in a vast ecosystem of open source technologies evolved around Kubernetes. They have a variety of techniques to facilitate and monitor solutions, including Prometheus, Package managers Helm and Cops, and container runtime Containerd. Most of the industry driving players are now fostering to shape the future of cloud computing, facilitating Kubernetes. In turn, they are leveraging the entire ecosystem of commercial offerings via market check and balance systems.


While companies have particular challenges to deal with, Kubernetes is playing a critical role in transforming the orchestration and management of containers. The platform has proven to do a great job in addressing those needs of transformations. However, it is worth mentioning that containers are not the only solution to every shipment problem. 

Additionally, Kubernetes is considered a default way to manage current containerized systems. It has been continuously evolving, and that is leading companies to work for overcoming some of the present current challenges. With the evolution of Kubernetes, we are continually expected to see increasingly sophisticated technology emergence. We can expect a significant involvement from giant technology players. The reason is, they are directly involved in nourishing the ecosystem by building commercial offerings on priority. 

Lastly, we all are on a bright, exciting point of the evolution of cloud-native technologies. Considering Kubernetes, it has succeeded in making increased headway into the industry. The growth is likely to continue fueling the shipping ecosystem and is expected to adapt and evolve more in the future.
