How to SOLVE the challenges in adopting Kubernetes at Scale
A report by IBM showed a rise in container usage for production enterprise workloads from 25 to 44 per cent. The same report also shared the top business benefits of adopting containers, such as improved application quality and reduced defects (59%), reduced costs (57%), and increased employee productivity (54%).
No wonder, most developers and ops teams are making use of container-based micro services architectures today, which make it much easier to test as well as deploy modern software and applications.
The Difference Between Container-Based and Legacy Application Approach
Containers are also hosted using the same legacy infrastructure of virtual machines or bare-metal servers. However, instead of hosting an enterprise application directly on the server, a containerized environment is used, which leads to faster deployment and also makes it possible to host individual components of application or microservices – creating numerous, customized apps for organizations instantly.
Other benefits include quick jumpstart – because you don’t need to boot the entire server for starting a single application. Containers also don’t require you to virtualize a complete operating system, leading to higher application density on a single server as compared to directly hosting applications on the same server.
Benefits of Container Orchestration and Kubernetes
Using Kubernetes for container management enables the development of lightweight and efficient applications that reduce cost and improve employee productivity. The stateless design of containerized applications enables Kubernetes to acquire storage resources as per requirement, which leads to max utilization of limited resources. Businesses also benefit from a single pane of glass view of their data centre and container management – leading to better control and saving unnecessary costs.
Containers are also suitable for upgrading your legacy applications and simplifying the migration to the cloud. With Kubernetes, container orchestration is simplified further, leading to easy portability, better security, and fast and straightforward deployment.
Challenges in adopting Kubernetes at Scale
While Kubernetes simplifies container management, we have noticed that enterprises often struggle in deploying Kubernetes at scale. Three critical challenges faced by enterprises are:
- Kubernetes deployment is a complex process, which can hinder its use as it requires service combinations, plug-ins, components, etc., for smooth functioning.
- As Kubernetes and its open-source components continue to evolve, enterprises often struggle in keeping up with the continuous update patches and bug fixes, which can hinder the production environment significantly.
- With most enterprises using a hybrid-cloud environment, they need to deploy Kubernetes on multiple infrastructures, such as public and private cloud infrastructure, adding to the complexity of the environment.
However, we believe that the benefits of using Kubernetes for container orchestration far outweigh the challenges;these challenges can be addressed by the following 5 key considerationsthat enable smooth deployment of Kubernetes for your organization.
- Enterprise readiness by monitoring workloads, SSL termination, certification management, etc., to run Kubernetes at scale.
- Take note of the fact that the Kubernetes ecosystem is continually evolving, and, on average, a new Kubernetes version is released every quarter. Therefore, you need to have a team (and plan) in place to keep up with these regular upgrades in real-time, with no downtime, if possible.
- Whether you wish to apply Kubernetes to a single or multiple infrastructure, be clear about your requirement and choose a Kubernetes solution that offers a consistent experience across various end-points – so that scaling to multiple or varied end-points is not an issue in the future.
- Another point to consider, especially for large organizations that want to support Kubernetes for a significant number of users, is factoring a multi-tenancy arrangement that separates users into different teams and also lets them isolate their test workload from the production workload.
- While managing multiple clusters, you also need to control the deployment decisions based on the workload, cluster type, and cluster parameters. Therefore, managing Kubernetes (or a containerized environment) at scale leads to questions of resource allocation, such as the sizing of the containers, choosing the right nodes for running an application inside a cluster, and when to scale up or scale down a cluster and by how much.
Containerization helps to create high availability and redundancy for the uptime of each module of the applications. In order to enable effective DevOps for enterprise-level applications, containerization is essential, and the Matilda Cloud platform offers an extensive set of features and facilitations. With our containerization solution, you will be able to extract the maximum potential from the cloud, be it AWS, Azure, or Oracle Cloud platform. We provide containerization solutions that live up to the current trends of the application workload.
