Case Study
Cloud Data Migration in Enterprises
Problem Statement
Enterprises relying on legacy on-premise systems often face challenges such as high maintenance costs, limited scalability, and accessibility issues. The organization aimed to migrate its legacy systems to the cloud to enhance performance, ensure better accessibility, and reduce infrastructure costs.
Challenge
The key challenges in cloud data migration included:
- Legacy System Complexity: Migrating outdated databases and applications without disrupting ongoing business operations.
- Data Security & Compliance: Ensuring secure data transfer while adhering to industry regulations like GDPR, SOC 2, and HIPAA.
- Downtime Minimization: Preventing business disruptions during the migration process.
- Cost Optimization: Managing cloud resources efficiently to avoid unexpected costs.
Solution Provided
A hybrid cloud migration strategy was implemented using AWS and Google Cloud to ensure a seamless transition. The migration process was designed to:
- Assess & Plan: Conduct a thorough analysis of existing infrastructure to determine the best migration approach.
- Automate Migration: Use cloud-native tools like AWS Migration Hub and Google Cloud Migrate to transfer workloads with minimal downtime.
- Ensure Security & Compliance: Encrypt data and implement IAM (Identity and Access Management) policies to control access.
- Optimize Costs: Leverage auto-scaling and serverless computing to reduce unnecessary cloud expenses.
Development Steps
