Managing Kubernetes on a Private Cloud: Best Practices

Cloud4C's Solutions for Kubernetes Management

Kubernetes ranks as the second-largest open-source project in the world, and the primary container orchestration tool for 71 of Fortune 100 companies.

Containers have gathered immense popularity in the recent years, as a method of packaging and deploying applications, much advantageous over traditional virtualization practices. But, managing containers is not easy, it is challenging in many ways and can also be time-consuming. This is where Kubernetes comes in. When it comes to modern IT infrastructure, the role of Kubernetes, as an open-source container orchestration platform, has been exceptional.

With the IT world continuously evolving, and more and more businesses moving their operations to the cloud –there is a pressing need for a scalable, and easily manageable infrastructure became paramount. Kubernetes emerged as the go-to solution, orchestrating application containers seamlessly across various cloud platforms! Although the best Kubernetes architecture for any organization depends on its needs and goals - in this blog, we will particularly delve deeper into Private Cloud and managing Kubernetes on it. So, let us dig in!

Understanding Kubernetes: A Journey

Originally created by Google to manage in-house application deployment, it has since evolved into an open-source, cloud-based, one-stop solution for automating the deployment, scaling, and management of containerized applications, including software and machine learning models. Kubernetes or K8 services, enables DevOps teams to keep up with software development requirements, maximize the utility of containers, and build cloud-native applications that can run anywhere.

According to the Cloud Native Computing Foundation's (CNCF) survey, Kubernetes went mainstream in less than a decade, and is currently showcasing a whopping number of organizations making use of the technology. Between 2021 and 2020 alone, Kubernetes adoption saw a 67% increase.

Some of the key features that give Kubernetes the much-deserved traction, include:

• Automated deployment and scaling of containerized applications
• Load balancing and service discovery
• Storage orchestration
• Self-healing
• Secret and configuration management

 

Kubernetes on Private Cloud: Why are some organizations preferring this route?

Why do organizations choose to run Kubernetes on a private cloud, compared to the “cake-walk” that is public cloud? There are a few very important reasons why:

Enhanced Security: Private clouds provide a secure environment for running applications and storing data, ensuring isolation and protection. When combined with Kubernetes, security measures are further enhanced through proper configuration and management of Kubernetes clusters. For example, an organization handling sensitive customer data can leverage a private cloud with Kubernetes to maintain compliance with data privacy regulations, while still maintaining security.

Increasing Scalability: Seamless scaling of clusters based on workload demands is possible in this setup, enabling businesses to efficiently handle fluctuations in traffic or resource requirements. During peak sales periods, an e-commerce company for instance can dynamically scale its Kubernetes clusters on a private cloud to accommodate increased website traffic without ever compromising performance.

 

Reduced Complexity: Automated features provided by Kubernetes simplify the management of clusters on private clouds, streamlining deployment and management tasks to reduce operational complexity. By utilizing Kubernetes implementation services, organizations can automate cluster provisioning, scaling, upgrades, and monitoring, while minimizing manual intervention and operational overheads.

Improved Availability: Kubernetes promises high reliability and fault tolerance in private cloud environments via continuous monitoring, self-healing capabilities, and fault recovery procedures. In the event of a container failure or a node outage, Kubernetes detects the cause and executes recovery operations to keep the application operational without manual intervention.

Control and Customization: Managing Kubernetes on a private cloud gives organizations greater control over their environment, allowing customized configurations, security measures, and networking settings according to their specific requirements. For businesses with unique operational needs, this level of control is essential.

 

Regulatory Compliance and Data Sovereignty: For industries such as healthcare, finance, government or those with sovereign clouds need extra protections to maintain, data sovereignty compliant cloud-native apps. In such cases, the adoption of Kubernetes on a private cloud is a great move.

Cost-Effectiveness: Even with public cloud's pay-as-you-go pricing model, hosting Kubernetes in a private cloud can prove more cost-effective for businesses with predictable workloads or specific performance demands.

8 Steps to Implement Kubernetes on Private Cloud

STEP 1: Choose a Private Cloud Provider	There are many private cloud providers to choose from, after thorough consideration, organizations need to choose the provider that meets both - their current and future business needs.
STEP 2: Installing Kubernetes	The most popular way is to use the Kubernetes distributions available from the providers. For example, Azure helps in installing Kubernetes through its Azure Kubernetes Service (AKS), offering a fully managed Kubernetes solution.
STEP 3: Configuring Kubernetes	Organizations must customize Kubernetes configurations to optimize performance and meet use cases that are specific to business needs. Networking, storage, security settings, and some other parameters can be customized.
STEP 4: Implementing Monitoring and Logging	To track the health, performance, and resource utilization of Kubernetes clusters in the private cloud, organizations can set up monitoring tools like Prometheus, Grafana, etc. Logging processes also need to be to be implemented to capture relevant information for troubleshooting and analysis.
STEP 5: Improving Security Measures	To boost the security of Kubernetes clusters within the private cloud setting, organizations can establish security protocols, network guidelines, role-based access control (RBAC) and other methods to protect applications and data stored.
STEP 6: Establishing Backup and Disaster Recovery	It is crucial to develop and execute a backup and disaster recovery plan for the Kubernetes environment. By backing up cluster setups, application data and essential resources, businesses can ensure continuity in case of disasters causing data loss or system breakdowns.
STEP 7: Incorporating Automation and CI/CD Practices	Utilizing automation tools like Kubernetes Operators can boost efficiency, reduce human errors and speed up the time to market. While implementing a CI/CD pipeline can automate software delivery effectively.
STEP 8: Regular Maintenance and Updates	To maintain up-to-date, stable and secure Kubernetes clusters, it's essential to carry out maintenance activities, like applying security updates and upgrading Kubernetes versions on a consistent basis.

The following are the steps to manage Kubernetes on a private cloud:

Managing Kubernetes on a Private Cloud: Best Practices

• Implement Role-Based Access Control (RBAC): Employ RBAC, for regulating access control to the Kubernetes API and setting user permissions
• Secure Secrets: Kubernetes secrets can be used to securely store sensitive data such as passwords and tokens.
• Kubernetes API Endpoint: Create a private Kubernetes API endpoint to regulate access and improve security.
• Secure Nodes and Pods: Harden and secure the operating systems running on nodes to protect against vulnerabilities.
• Multifactor Authentication (MFA): Consider using Multifactor Authentication (MFA) to improve authentication security when accessing the Kubernetes API.
• Use Managed Services: To simplify management tasks and ensure security measures, check for managed Kubernetes services from cloud providers like Oracle, Azure, AWS.
• Proactive Threat Monitoring: Monitor threats and vulnerabilities in managed Kubernetes clusters to reduce risks and protect against any security breaches.
