Standardizing Multi-Cluster Kubernetes for 100+ Applications

The Challenge

Imagine managing over 100 applications across multiple Kubernetes clusters, each with its own deployment patterns, security policies, and operational quirks. This was the reality for our client, a large enterprise with a complex application landscape.

Their developers faced inconsistency across environments, deployments were error-prone, and security vulnerabilities often surfaced due to misconfigured permissions. The infrastructure team was drowning in manual tasks, from provisioning clusters to managing IAM policies.

They needed a unified approach to multi-cluster management, ensuring developer autonomy without sacrificing security and governance.

How We Solved It

1. GitOps for Standardized Deployments – By integrating FluxCD, we established a common deployment workflow, eliminating inconsistencies across clusters.
2. Automated Cluster Provisioning – We used Terraform and Helm to define and provision clusters in a repeatable manner, reducing manual errors.
3. Self-Service Infrastructure via Ticketing System – Developers gained access to an automated ticketing system, allowing them to request resources without manual intervention.
4. IAM & Access Control Management – Role-based access controls were tightly integrated, ensuring teams had just enough privileges to deploy their applications securely.
5. Centralized Observability – We unified logging, monitoring, and alerting with Prometheus, Loki, and Grafana, ensuring issues were detected before escalating.

Takeaway: Automating Kubernetes cluster management and enforcing GitOps workflows enables large-scale application deployments while maintaining security and governance.
