Cloud Migration Case Study

Modernizing Infrastructure with DevOps Enablement

About the Project

A fast-growing healthcare technology company needed to modernize its legacy on-premise infrastructure to support new digital services and rapid innovation. Their existing systems, spread across aging data centers, suffered from high maintenance costs, limited scalability, and frequent downtime during peak usage.

To address these challenges and unlock business agility, the company partnered with Spundan to plan and execute a cloud migration to AWS, combined with robust DevOps enablement to ensure faster, more reliable software delivery once in the cloud.

Challenges Faced

Prior to the migration, the organization faced several critical pain points:

Rigid Legacy Infrastructure

Scaling resources to meet demand spikes required manual provisioning and significant lead time.

Slow Release Cycles

Manual deployments and inconsistent environments made releasing new features unpredictable and risky.

High Operating Costs

Maintaining aging hardware and data center contracts strained IT budgets.

Security & Compliance Gaps

Legacy systems lacked modern security controls and required extensive manual audits.

Spundan's Solution

Spundan designed and delivered a phased migration and DevOps enablement program that balanced speed, security, and minimal disruption.

Key solution pillars:

Cloud Readiness Assessment

We conducted a detailed discovery of legacy workloads, dependencies, and compliance needs to design a migration roadmap.

Application Re-Architecture

Non-cloud-native applications were containerized and refactored where feasible, reducing lift-and-shift inefficiencies.

Infrastructure as Code (IaC)

All cloud infrastructure — VPCs, compute, storage, networking, and security — was codified using Terraform and deployed through automated pipelines.

CI/CD Pipeline Implementation

Integrated continuous integration and deployment workflows to automate build, test, and release cycles.

Cloud Security & Compliance

Deployed security best practices, including IAM policies, encryption, auditing, and automated compliance checks aligned with HIPAA.

Team Enablement

Provided training and hands-on sessions to upskill development and operations teams in cloud operations and DevOps workflows.

Implementation Timeline

The transformation was executed in three phases over eight months:

1

Planning & Assessment

Workload discovery, dependency mapping, and cloud landing zone setup.

2

Pilot Migration & DevOps Foundation

Migrated selected applications as pilots; designed and validated CI/CD pipelines and IaC processes.

3

Full Migration & Optimization

Migrated remaining workloads in waves, refined pipelines, and implemented cost optimization and governance policies.

Key Outcomes

“Spundan's expertise helped us modernize without disruption. We now deploy updates in hours instead of days and scale on demand — while staying compliant with healthcare regulations.”
— Chief Technology Officer, Healthcare Tech Client

  100% migration of mission-critical applications to AWS with zero unplanned downtime.

  50% faster deployment cycles with new CI/CD workflows.

  30% reduction in infrastructure costs through auto-scaling and pay-as-you-go resources.

  Improved security posture with automated compliance checks and cloud-native controls.

  Empowered teams with the skills and tools to manage and scale their cloud environment independently.

Lessons Learned

Plan in Waves

Phased migrations with pilot workloads ensured issues were resolved before full rollout.

IaC is Non-Negotiable

Codifying infrastructure reduced human errors and simplified scaling.

DevOps & Cloud Go Hand-in-Hand

Automation is key to realizing the true value of the cloud.

Upskilling is Essential

Training and coaching ensured teams could own and optimize the new cloud environment.

Conclusion

By adopting a phased cloud migration strategy combined with DevOps enablement, the media company successfully modernized its IT landscape. Automation and CI/CD practices became foundational to their new cloud-native operating model, enabling them to innovate faster, ensure high availability, and improve user experiences.
