What are the Challenges of Kubernetes Day 2 Management?

Kubernetes is an open-source container orchestration and management solution. It is the gold standard for container management, automation, and scaling. Its popularity as a solution allows it to transfer workloads between on-premises, hybrid, and public cloud infrastructure with ease.

Whether small or big companies migrating to Kubernetes, they have been improved in terms of development, less friction, agility, and so on. With Kubernetes, it is easy for companies to scale applications, deploy services rapidly, roll out new features, and optimize hardware using the required resources. What companies need is to monitor, troubleshoot, and maintain applications to meet the agility, compliance, and security requirements.

The Kubernetes application lifecycle has several stages, including design, deployment, and operations, that developers must consider while installing clusters and sustaining them over time. The procedures performed by organizations to streamline and refine the Kubernetes stack for automating the platform’s management come into Day 2 Operations.

The phases of the organization's Kubernetes application lifecycle are referred to as "days" in this context. The design process begins on Day 0, the deployment phase begins on Day 1, and the application transitions from development to production on Day 2.

Day 2 Kubernetes management plays a vital role once you deploy everything. It does not seem to be easy as the user faces many challenges during the phase. The challenges in Kubernetes Day 2 management are quite common and multifaceted as operations teams increase nodes and scale apps to work for business objectives in the right direction.

In this phase Kubernetes operations entails not just upgrading your application but also the way it is run in production. So that applications meet security, agility, and compliance requirements, organizations must consider monitoring, maintenance, and troubleshooting.

Day 2 operations are the most time-consuming for any application in production, as organizations must figure out how the application will fit into a larger technical architecture.

Some of the challenges are given below:      

Security: Kubernetes gives a way to run containers and while managing day 2 operations, it becomes typical to manage or balance security. It is needed to put security automation into the DevOps cycle pipeline. For ensuring better outcomes, the organizations must implement best security practices and test whether CI/CD pipelines are functional tests or automated units.  

To minimize security risks, it is highly needed to make intelligent choices and handle security risk factors. Managing security in any application can be expensive as it needs to be continually controlled and re-evaluated. Right from public or private Kubernetes access to workload security access, there are various security options available! However, all require a measured choice to solve a single point of failure and other pressure on the DevOps team.

Observability: Day 2 Kubernetes management needs highly advanced observability features. These features are not provided by monitoring tools that are used in the Kubernetes development environment. Kubernetes clusters running in production are characteristically deployed alongside different technologies that should be debugged to determine the root cause of the issue.  

In terms of observability, you should understand how quickly you are getting notifications if anything is failing, how rapidly you are getting triggered by any problem, how effectively you can monitor these problems and mitigate them, and how you can find out the root cause of the problem. All these are phases of observability that assist in relieving the consumer impact or restoring the service to a suitable level of performance and availability.

Scalability: Scalability is crucial in Kubernetes day 2 management due to the reason that when companies or engineers start working on Kubernetes, they could have some clusters running. But when some projects get deployed, Kubernetes can spread faster than before. Therefore, IT people or engineers striving for Kubernetes day 2 management should think about the location of the cluster, number of clusters, size of the cluster, and the physical nodes associated with the cluster. The larger the cluster will be, the more challenging it will be to manage. It becomes quite typical to troubleshoot a 100-node cluster. So, it is recommended to troubleshoot a smaller size cluster if it fails. This will make it easy to isolate issues, monitor, find the right balance and work further.

Apart from these, storage, high availability, development can also be some of the challenges that organizations face during Kubernetes day 2 management, specifically when working on business-critical applications.
