Migration & Modernization
Migration & Modernization Services 🚀
Migration and modernization involve moving applications, data, and workloads from legacy systems to a cloud-native or optimized environment. This process enhances scalability, performance, cost-efficiency, and security while ensuring long-term business agility.
🔄 Cloud Migration Strategies (The 6 R’s)
Different approaches depend on business needs and technical complexity:
1️⃣ Rehosting ("Lift & Shift")
- Moves applications without code changes.
- Pros: Fast, low risk, minimal effort.
- Cons: Doesn't optimize for cloud-native benefits.
- Example: Migrating on-prem VMs to AWS EC2 or Azure Virtual Machines.
2️⃣ Replatforming ("Lift, Tinker & Shift")
- Minor optimizations (e.g., using managed databases or containerization).
- Pros: Improves performance without full redesign.
- Cons: Requires some modifications.
- Example: Moving from self-managed MySQL to Amazon RDS.
3️⃣ Refactoring / Rearchitecting
- Redesigning applications to be cloud-native (microservices, serverless).
- Pros: Improves scalability, agility, and cost savings.
- Cons: More effort and development time.
- Example: Breaking a monolithic app into Kubernetes-based microservices.
4️⃣ Repurchasing
- Replacing on-prem software with SaaS alternatives.
- Pros: No maintenance, automatic updates.
- Cons: May require data migration and user adaptation.
- Example: Moving from legacy CRM to Salesforce or HubSpot.
5️⃣ Retaining
- Keeping certain workloads on-prem due to security, compliance, or cost.
- Example: Highly sensitive government data.
6️⃣ Retiring
- Decommissioning outdated applications that are no longer needed.
- Example: Replacing old HR systems with Workday or SAP SuccessFactors.
🚀 Benefits of Migration & Modernization
