Manual Deployments
Changes were pushed manually to clusters, often causing config drift and inconsistencies across environments.
Kubernetes GitOps with Progressive Delivery
Managing modern, cloud-native applications at scale requires more than just container orchestration — it demands an infrastructure and delivery approach that is automated, auditable, and resilient.
A global SaaS company delivering high-traffic collaboration tools partnered with Spundan to modernize its Kubernetes infrastructure management using GitOps, while adopting Progressive Delivery to safely roll out new features with minimal risk and zero downtime.
The client operated dozens of Kubernetes clusters across AWS and Azure regions, hosting hundreds of microservices. Frequent deployments, manual configurations, and high release risks were resulting in downtime, rollback headaches, and inconsistent environments.
Before implementing Kubernetes GitOps with Progressive Delivery, the client faced these key challenges:
Manual Deployments
Changes were pushed manually to clusters, often causing config drift and inconsistencies across environments.
High-Risk Releases
All-or-nothing rollouts meant any deployment failure could impact thousands of active users.
Limited Rollback Options
Rolling back problematic updates required manual intervention and downtime.
No Unified Control
Infrastructure definitions were scattered across local files and cloud consoles, lacking a clear source of truth.
Spundan's cloud-native engineering team designed and implemented a Kubernetes GitOps framework combined with Progressive Delivery, enabling safe, resilient updates with maximum control.
Key solution pillars:GitOps Toolchain
Integrated FluxCD and ArgoCD for continuous reconciliation — keeping clusters in sync with the declared state in Git repositories.
Progressive Delivery Patterns
Enabled automated canary deployments, blue-green strategies, and feature flag rollouts using tools like Flagger and native Argo Rollouts controllers.
Automated Drift Detection
Deployed continuous drift detection and self-healing to ensure actual cluster state always matches the desired Git state.
Rollback on Demand
Configured instant rollbacks to stable releases directly through Git version control — with no need for manual cluster edits.
Secure Workflows
Enforced RBAC policies, pull request approvals, and code reviews for every infrastructure or application change.
Developer Training
Provided workshops to train development and platform teams in GitOps workflows and progressive delivery best practices.
The program was rolled out in three phases over four months:
Assessment & Architecture
Reviewed existing deployment processes and cluster management; designed GitOps and progressive delivery workflows.
Pilot Projects
Implemented GitOps and canary releases for select high-traffic services to validate risk mitigation and rollback strategies.
Full Rollout
Expanded GitOps and progressive delivery to all clusters and services; integrated automated monitoring and alerting.
“With Spundan's GitOps and Progressive Delivery solution, we deploy confidently, recover instantly, and deliver new features without downtime — no more all-or-nothing releases.”
— Head of Platform Engineering, SaaS Client
100% of Kubernetes infrastructure and workloads version-controlled in Git as a single source of truth.
Zero configuration drift across clusters due to continuous reconciliation.
Risk-free rollouts: Canary and blue-green deployments reduced production incident rates by over 70%.
Mean time to recovery (MTTR) reduced by 50% with instant rollbacks via Git history.
Developer ownership: Engineering teams manage updates through simple pull requests with full audit trails.
Progressive Delivery Builds Confidence
Canary and blue-green rollouts helped teams release features safely without impacting all users at once.
Automation is Non-Negotiable
Continuous reconciliation and automated rollbacks eliminate manual errors and downtime.
Collaboration Wins
GitOps workflows aligned developers and operations on a shared, auditable process.
By combining Kubernetes GitOps with Progressive Delivery, this SaaS leader transformed how it manages cloud-native applications — achieving safer, more reliable deployments, consistent environments, and faster recovery from issues.
