Case Study: On-Prem to Cloud Migration

A growing SaaS company with legacy on-premises infrastructure facing challenges in scaling operations and managing costs.

45%

Cost Reduced

80%

Performance Improved

Objective:
Migrate the client’s existing infrastructure to the cloud to improve scalability, enhance system performance, and reduce operational costs, while ensuring zero downtime during the transition.


Challenges

  1. Limited Scalability: The on-premises infrastructure couldn’t handle the growing user base and workload.
  2. High Maintenance Costs: Maintaining physical servers and manual scaling led to inefficiencies.
  3. Downtime Concerns: The client couldn’t afford significant downtime as they supported a global customer base.
  4. Data Security: Ensuring compliance and secure migration of sensitive customer data was critical.

Solution Provided by Compute Universe

Our team developed and executed a comprehensive cloud migration strategy tailored to the client’s needs:

1. Cloud Selection and Planning:

  • Platform Choice: Migrated to AWS for its scalability, cost-effectiveness, and diverse managed services.
  • Assessment: Conducted a thorough audit of the client’s on-premises environment to plan resource allocation in the cloud.
  • Migration Roadmap: Created a step-by-step migration plan with minimal disruption to operations.

2. Infrastructure Setup:

  • Configured AWS EC2 instances for application hosting with auto-scaling enabled to handle peak loads.
  • Migrated databases to Amazon RDS for high availability and automated maintenance.
  • Used AWS S3 for scalable storage of static files and backups.
  • Set up AWS CloudFront for content delivery to reduce latency for global users.

3. Secure Data Migration:

  • Encrypted sensitive customer data during transit using AWS Key Management Service (KMS).
  • Established secure VPN tunnels for transferring data from on-premises systems to the cloud.

4. Zero Downtime Deployment:

  • Used blue-green deployment strategies to ensure uninterrupted services during the migration.
  • Implemented AWS Elastic Load Balancers (ELB) to manage traffic between the legacy system and the new cloud infrastructure.

5. Monitoring and Optimization:

  • Configured AWS CloudWatch to monitor resource usage and system performance in real-time.
  • Optimized costs with Reserved Instances and Savings Plans, resulting in long-term savings.

6. Post-Migration Support:

  • Provided ongoing monitoring and maintenance, ensuring the cloud environment remained optimized and secure.
  • Trained the client’s internal IT team to manage and scale the infrastructure as needed.

Results

  • Improved Scalability: The cloud infrastructure seamlessly handled a 40% increase in user traffic post-migration without performance degradation.
  • Cost Reduction: The client saved 30% on infrastructure costs by leveraging AWS managed services and cost-optimization tools.
  • Zero Downtime: The migration was completed with zero impact on end-users, maintaining the client’s reputation for reliability.
  • Enhanced Security: Data encryption and secure configurations ensured compliance with industry standards, improving customer trust.
