Cloud Migration Strategies (The 6 R’s)

1. Rehost (Lift & Shift)

Pindahkan aplikasi as-is ke cloud tanpa modifikasi. Pros: Cepat, risiko rendah Cons: Tidak optimal, biaya bisa lebih tinggi

2. Replatform (Lift & Reshape)

Optimasi minor saat migrasi (misalnya: managed database). Pros: Balance speed & optimization Cons: Memerlukan testing lebih

3. Repurchase (Replace)

Ganti dengan SaaS solution (misalnya: on-prem CRM → Salesforce). Pros: Modern features, managed Cons: Data migration, learning curve

4. Refactor (Re-architect)

Redesign aplikasi untuk cloud-native architecture. Pros: Fully optimized, scalable Cons: Effort tinggi, time-consuming

5. Retire

Decommission aplikasi yang tidak diperlukan. Pros: Reduce complexity, save cost Cons: Perlu careful analysis

6. Retain

Keep on-premise untuk aplikasi tertentu. Pros: Flexibility Cons: Hybrid complexity
