Why Migrate to the Cloud?
Cloud computing offers scalability, resilience, and cost efficiency that traditional on-premises infrastructure simply cannot match. For SMEs, the cloud levels the playing field, providing access to enterprise-grade technology without enterprise-scale budgets.
Phase 1: Assessment
Before migrating anything, you need a clear picture of your current environment:
- Inventory all applications, services, and data stores
- Classify workloads by criticality and complexity
- Identify dependencies between systems
- Assess current costs (hardware, licences, electricity, staffing)
- Define your compliance and data residency requirements
Phase 2: Planning
With your assessment complete, plan the migration:
- Choose the right cloud model: public, private, or hybrid
- Select your cloud provider(s): Azure, AWS, or Google Cloud
- Decide your migration strategy for each workload: rehost, refactor, replace, or retire
- Design your target architecture, including networking, security, and identity
- Create a detailed timeline with milestones and rollback plans
Phase 3: Execution
Execute the migration in waves, starting with low-risk workloads:
- Migrate non-critical workloads first to build confidence
- Run parallel environments during transition periods
- Test thoroughly before decommissioning on-premises systems
- Communicate changes to users with adequate training
Phase 4: Optimisation
Migration is not the end — it is the beginning of continuous optimisation:
- Monitor performance and costs from day one
- Rightsize resources based on actual usage data
- Implement tagging and cost allocation
- Review and optimise quarterly
