Introduction to Kubernetes
Before explaining the Kubernetes Implementation strategy, we need to understand how people within the organization are using Kubernetes today.

The stage team uses Kubernetes to implement a specific program or specific workload tied to a particular business function.On-Premise
It is another way to incorporate the emergence of computer compounds. Edge computing is an offline network of Kubernetes-managed clusters on the site. It is a standard setup for storefronts, as well as factories.Multi-Cluster
One common way we see it is with many individual groups working in the organization. There are different types of Kubernetes, each using different software stack variants. Each team runs a cluster transformation to meet its complexity and business needs.How to Implement Kubernetes?
Because of their flexibility, failure, and self-healing properties, Kubernetes implementation is the best for production purposes. Kubernetes has a robust and rich open-source ecosystem with adequate security.
There are many open-source projects available at CNCF, which you can choose to help build the platform and to lay the groundwork for your teams to increase velocity. However, how you go about picking and implementing those projects can be a significant challenge for most organizations. In addition to promoting and maintaining an ecosystem of open source, vendor-neutral projects, another goal of CNCF is to provide building complexes for a common cloud-native platform that enterprises can use within their organizations.
Four major steps to implement Kubernetes are:- Deploy
- Scale
- Update
- Debug

What are the Challenges in Kubernetes Implementation?
- Cultural Changes with Development Teams
- Complexity
- Lack of Training
- Security
- Monitoring
- Storage
- Networking
At the beginning of the Kubernetes adoption cycle, many companies' challenges were security and savings. Still, now these concerns have shifted toward planning and expanding your Kubernetes application teams for application development.

How to Manage Kubernetes?
Below is the list of various kubernetes services offered for its successful deployment and management:Self-managed Kubernetes
There are a plethora of merits and demerits of using Kubernetes self-managed service. One of the major merits is its flexibility in configuration management and deployment. Given below is the list of some open-source tools used for self-management in Kubernetes:- kubeadm
- Kops
- Rancher RKE
- Weaveworks EKP
- Roll your upstream K8S
Hosted Kubernetes
- Google GKE
- Amazon EKS
- Digital Ocean
- Azure AKS
- Oracle, IBM, and others
Overview to Multi-Tenant And Multi-Cluster Kubernetes
Multi-Tenant
Multi-tenancy is a standard structure for organizations with multiple applications running in the same environment. Different teams (such as developers and IT Ops) share the same Kubernetes environment.
Multi-Cluster
If there are multiple clusters, you usually create services with the same server in each group and place those service instances behind the load balancer (AWS Elastic Load Balancer, GCE Forwarding Rule, or HTTP Load Balancer) all-in-one so that single-component failures are invisible to users at the end.
Multiple clusters not only add to overhead and maintenance headaches, but they can also incur extra costs and are potentially insecure if not appropriately managed.

Approaches (Centralized and Decentralized)
You can take a few different options when introducing Kubernetes to your organization: the Decentralized work model or one centralized with a set of shared services and applications.
Decentralized
With a decentralized approach, teams can wrap their Kubernetes clusters whenever needed and on-demand.
Benefits
- Teams can create what they need accordingly.
- Promotes innovation and provides a high degree of independence.
Challenges
- It is difficult to manage the development, tools, and security of your entire organization.
- Reduce carrying. It is difficult to manage code for all projects.
Centralized
Create your own set of tasks and with fully integrated features that are always available throughout your organization.
Benefits
- You can focus on security and compliance.
- It's easy to submit code project projects.
- Cost-effective.
Challenges
- Integration with your entire stack.
- It can be very difficult to master skills if not done correctly.
How to Manage Addons For Kubernetes?
Here are some of the addons that could give a practical approach:
- Policy Management
- User Management and Administration
- Cluster Provisioning and Lifecycle Management
Policy Management in Kubernetes
The basic policy management layer is about ensuring adequate compliance and controls throughout your Organization's Kubernetes operations.
It will have control planes that allow your groups to define policies and apply them to all groups that use Kubernetes and all other groups in the organization.
User Management and Administration in Kubernetes
The primary purpose of any Kubernetes platform is to provide a service shared with your users, making it easy for them to use. It would help if you prioritized how to handle a large number of users and the experience you can offer them. Understanding the user journey starts by defining how users will use Kubernetes.
Making sure your platform supports the default Single login such as LDAP. You'll seek the authority to authorize both individuals and groups to access them specific titles or spaces, and the ability to elaborate on different roles that fit your business needs.
Kubernetes Cluster Provisioning and Lifecycle Management
An effective way is to provide a cluster and support your team to upgrade it to the latest version of Kubernetes. Other measures will include integrated monitoring, backup, restoration, and infrastructure provisioning and automation.
If you are going to use Kubernetes distribution, it is essential to check whether that distribution is compatible with Kubernetes expansion or modified that would delay the financing of the latest developments in the community.
What are the Benefits of Implementing Kubernetes Strategy?
Security
The most important benefit of the centralized approach is that IT can control RBAC settings and implement a unified system to authentication using Active Directory or other enterprise network authentication. It allows you to set who sees when, when, and who has permission to suspend roles.
These are other policies that you can set, such as the general network policy and third party software for image capture software and other technical features for distribution pipes. Providing shared services allows you to manage compliance with other regulatory obligations easily.
Flexibility
The main difficulty of the collection method is to bring your shared resources over to other DevOps stacks. DevOps teams will want some freedom in choosing the tools they like to work with daily. While you will not include every single project in a standard way, you will want to provide your DevOps team with a choice.

A Comprehensive Approach
All-in-all, Kubernetes is an open-source platform that helps in the management of containerized workloads and also in automating computer applications deployment and scaling.
There are a plethora of cloud service providers that are offering kubernetes-based Platform as a service. Implementation of Kubernetes has come up as the best approach for DevOps to configuration management and deployment at a large scale.
