Kubernetes adoption has witnessed exponential growth from 2020 to 2025, driven by the surge in cloud computing, the rise of microservices and continuous improvements in user experience. This powerful container orchestration platform has become the industry standard, with over 90% of enterprises now using or evaluating it, according to the CNCF (Source: CNCF Annual Survey). The vibrant community and expanding use cases, from edge computing to AI/ML, ensure that Kubernetes will continue to dominate the container landscape in the years to come.

As Kubernetes adoption scales across organizations, a critical need has emerged for robust fleet management solutions. Managing and operating numerous Kubernetes clusters across diverse environments (on-prem, cloud, edge) presents significant challenges. These include complex configurations, inconsistent policies and difficulties in scaling operations efficiently. Kubernetes fleet management solutions address these challenges by providing centralized control, automated operations and enhanced security across the entire Kubernetes landscape.

Key considerations for effective fleet management 

Let us look at five key considerations to manage your existing fleet of Kubernetes clusters and ensure it

1. Lifecycle management of heterogeneous Kubernetes clusters
   Almost all Kubernetes fleet management solutions offer the ability to import and view your existing clusters. However, many offer limited functionality to modify and manage the lifecycle of these clusters, such as Kubernetes upgrades. Due to this, platform teams still need to navigate to respective Kubernetes provider consoles such as Azure, GCP or AWS, Red Hat OpenShift consoles to perform such tasks. To overcome these operational overheads, shortlist a fleet management solution that can import almost all or most of your heterogeneous Kubernetes clusters and manage their lifecycle.
2. Continuous Integration with your ITSM solution
   The product should offer continuous integration with your ITSM solution such as ServiceNow to ensure seamless service management for self-service catalog, real-time CMDB updates etc. Most providers offer one-time integrations at an additional professional services cost however such one-time integrations suffer from introducing enhancements and addressing new requirements with fast evolution of cloud native ecosystem. Instead, consider fleet management solutions with native integrations and a strong partnership with ITSM solution providers.
3. Unified policy, security and compliance
   Fleet management solution must offer unified policy management for all your clusters with readily available policies for the platform, applications, security and compliance. You should also look for audit policies to simplify your regulatory compliance commitments, plus features to inform and remediate policy violations. Apart from these must-haves, evaluate the creation of custom policies. Is it easy to create custom policies, or does it require your platform teams to learn a proprietary Infrastructure-as-Code language or even depend upon developers or professional services?
4. Deployment architecture and maintenance simplicity – SaaS and Self-hosted
   Today, most software is available as SaaS, to provide optimal, consistent user experience and eliminate the maintenance overhead. On similar lines, Kubernetes fleet management solutions are primarily offered as SaaS where they connect to your clusters and ingest data over a secure connection for intelligent insights and management. However, it might not be a way forward for sensitive, regulated organizations such as Banking and Financial services, Federal Government, Utilities etc. and even air-gapped environments, where the self-hosted solution is preferred. If this applies to your organization, do check for simplicity of installation, frequency of security fixes, ease of maintenance cycles and upgrades of these solutions.
5. Edge management capabilities
   IT architectures are continuously evolving into distributed systems and we have multiple Kubernetes projects and solutions primarily designed for distributed and edge computing use cases. K3s, KubeEdge, and Micro K8s are some of the leading examples of trimmed-down versions of Kubernetes that thrive in a typical edge site with characteristics such as computing resource constraints, unreliable network connectivity, limited bandwidth, environmental considerations, etc. We should evaluate the ease of spawning new clusters on Edge with capabilities such as ‘zero touch provisioning’ and assess how the fleet management solution overcomes chaos situations such as disruptions during upgrades, extended network outages and local storage and subsequent synchronization of logs and metrics.

Apart from these five key considerations, it is worth exploring complimentary features of the fleet management tools such as integrated FinOps or cost management capabilities Kubernetes clusters, snapshot-based backup of clusters and hosted workloads, etc.

We at HCLTech utilize a detailed checklist to understand the strengths of available leading tools to ensure we can advise our customers with the best way forward in a vendor-agnostic manner. Our Kubernetes fleet management solution offers comprehensive capabilities across the entire cluster lifecycle, including provisioning, updates and decommissioning, with support for major platforms like AWS, Azure, GKE and more. It enables seamless discovery, management and access to clusters via both GUI and CLI. Advanced resource management features allow cross-cluster search, modification and logical grouping. Application deployment is streamlined through Git, Helm and GitOps integration, while intelligent workload placement leverages capacity, policy and tagging. Robust policy, security and compliance frameworks ensure governance with auditing and remediation. Observability is enhanced through alerting, multicloud monitoring and topology visualization. The solution supports flexible deployment architectures, integrates with automation and ITSM tools and ensures resilient networking and business continuity with backup and disaster recovery options.

Conclusion

As Kubernetes continues to evolve as the cornerstone of modern infrastructure, effective fleet management becomes a necessity and a strategic imperative. Organizations must navigate the complexities of multi-cluster environments with solutions that offer scalability, security and operational simplicity. By focusing on key considerations such as lifecycle management, integration, policy enforcement, deployment models and edge capabilities, enterprises can unlock the full potential of Kubernetes. At HCLTech, we are committed to guiding our clients through this journey with a vendor-agnostic approach, leveraging our comprehensive evaluation framework. Whether you're validating your current solution or exploring new options, our expertise is here to help you make informed, future-ready decisions.
