Cloud migration is a strategic decision that can unlock significant business value for organisations of all sizes. At Commercial Networks, we see more and more companies moving away from legacy infrastructure and embracing the scalability and flexibility of the cloud.
Cloud migration is the process of transferring digital assets, such AS data, applications, IT processes, and workloads, from on-premises data centres to cloud-based environments. This may involve public clouds (e.g., AWS, Microsoft Azure, Google Cloud), private clouds, or a hybrid model that blends both. Crucially, migration isn’t just about moving systems, it often requires rethinking and reconfiguring workloads to fully harness the cloud’s potential.
Cloud Migration Explained
At its core, cloud migration enables organisations to modernise IT infrastructure, improve efficiency, and reduce costs. It can be AS simple AS relocating existing workloads or AS advanced AS re-engineering applications to take advantage of features such AS serverless computing and containerisation.
The right approach depends on your business objectives, current infrastructure, and long-term digital strategy. Below are some of the most common types of cloud migration.
Types of Cloud Migration
Lift-and-Shift Migration
A straightforward method of moving applications with minimal changes. It’s fast and cost-effective but doesn’t maximise cloud-native benefits.
Replatforming
Involves making moderate adjustments to applications so they run more efficiently in the cloud, without altering their core architecture.
Refactoring/Rearchitecting
A more advanced approach where applications are redesigned to leverage cloud-native technologies. Though more complex, it delivers long-term scalability and agility.
Hybrid Migration
Combines on-premises and cloud-based environments, giving businesses flexibility over where workloads run.
Multi-Cloud Migration
Distributes workloads across multiple providers, reducing reliance on a single vendor and improving resilience.
Benefits of Cloud Migration
Migrating to the cloud is more than a technical upgrade, it’s a competitive advantage. Here are some of the key benefits of cloud migration:
- Cost savings – Reduce hardware and maintenance costs, with pay-AS-you-go pricing models.
- Scalability – Scale resources instantly to meet demand.
- Flexibility – Enable secure remote working and global collaboration.
- Performance – Access high-speed, low-latency infrastructure.
- Disaster recovery and security – Benefit from enterprise-grade protection and backup systems.
- Innovation – Unlock tools such AS AI, machine learning, and advanced analytics.
The Cloud Migration Process
A successful migration requires careful planning. A typical roadmap includes:
- Assessment and Planning – Analyse existing infrastructure, define goals, and choose the right cloud model (public, private, hybrid, or multi-cloud).
- Choosing a Provider – AWS, Azure, and Google Cloud are the leading players. Select based on business needs and budget.
- Migration Strategy – Decide whether lift-and-shift, replatforming, or refactoring fits your requirements.
- Data Migration – Transfer data securely, minimising downtime.
- Testing and Optimisation – Run workloads in the new environment, fine-tuning for performance.
- Deployment and Monitoring – Roll out the new system and use management tools to track cost, usage, and security.
Challenges of Cloud Migration
Like any strategic IT project, migration comes with challenges:
- Downtime – Temporary disruption during the move.
- Security concerns – Sensitive data must be protected during transfer.
- Compatibility issues – Legacy applications may need adaptation.
- Cost management – Without oversight, cloud costs can escalate.
- Change management – Staff may require training to adapt to new workflows.
These challenges can be mitigated with the right expertise, tools, and planning.
