What Is Cloud Migration?
It’s the process of moving your business data, applications, servers, and workloads from on-premise systems to a cloud-based environment.
In simple words, it means shifting your IT setup from physical infrastructure to a secure and scalable cloud platform. This type of migration in cloud computing allows businesses to become more flexible, reduce infrastructure costs, and easily scale resources based on demand.
Cloud migration can take different forms, including:
- Moving from on-premise systems to the cloud
- Switching from one cloud provider to another (cloud-to-cloud migration)
- Using a hybrid setup that combines on-site and cloud systems
- Adopting a multi-cloud approach with multiple providers
For example, a company might move its databases, applications, and files to the cloud while keeping certain legacy systems running on local servers.
This shift is accelerating across industries. According to Gartner, global spending on public cloud services reached around $675.4 billion in 2024, growing by over 20% compared to the previous year.
Similarly, Flexera’s 2024 report shows that nearly half of all workloads are already running in the public cloud, and about 89% of organizations are using multi-cloud environments.
All of this clearly shows that cloud migration is no longer just an option—it has become a smart and necessary step for businesses looking to grow and stay competitive.
How Does Cloud Migration Work?
The cloud migration process isn’t something you do overnight. It requires careful planning and a step-by-step approach to ensure everything moves smoothly without disrupting business operations.
1. Assess Current Infrastructure
The first step is to analyze your existing IT environment. This includes reviewing servers, applications, databases, and dependencies to decide what should be migrated, updated, or removed.
2. Back Up Critical Data
Before starting the migration on cloud, it’s essential to create secure backups of all important data. This reduces the risk of data loss and keeps your business protected during the transition.
3. Build a Cloud Migration Strategy
Next comes creating a clear cloud migration strategy. This involves choosing the right cloud platform, setting timelines, defining security measures, and deciding whether the migration will happen in phases or all at once.
4. Migrate Data and Applications
Once the plan is ready, the actual migration in cloud computing begins. Data, applications, and workloads are transferred to the cloud environment based on the selected approach.
5. Test and Optimize
After the migration is complete, systems are tested to ensure everything is working properly. Performance checks, security validation, and optimization help improve efficiency and reliability.
A well-structured cloud migration process helps businesses minimize downtime, improve system performance, and transition smoothly to a modern IT environment.
What Are the Types of Cloud Migration?
Not every business follows the same approach when moving to the cloud. The right cloud migration strategy depends on your current systems, business goals, and how much transformation you’re aiming for.
Here are the most common types of cloud migration:
1. Rehosting (Lift and Shift)
This is one of the quickest ways to handle migration on cloud. Applications and workloads are moved as they are, without major changes. It’s ideal for businesses looking for a fast and cost-effective solution.
2. Replatforming
In this approach, applications are moved to the cloud with slight improvements. While the core system remains the same, small adjustments are made to enhance performance and scalability.
3. Refactoring (Re-architecting)
This method involves redesigning applications to fully utilize cloud capabilities. It’s best suited for businesses planning long-term digital transformation and scalability.
4. Repurchasing
Here, businesses replace their existing software with cloud-based SaaS solutions. For example, switching from a traditional CRM to a cloud-based CRM platform.
5. Retaining
Some systems may still need to stay on-premise. In this case, businesses keep certain critical applications locally while migrating others to the cloud, creating a hybrid environment.
6. Retiring
This step involves identifying outdated or unused applications and removing them instead of migrating. It helps reduce complexity and unnecessary costs.
Choosing the right approach is a key part of successful cloud migration services, as it directly impacts performance, cost, and future scalability.
What Are the Cloud Migration Deployment Models?
When planning a cloud migration strategy, choosing the right deployment model is just as important as choosing the migration type. The right model depends on your business goals, security needs, compliance requirements, and budget.
Here are the most common cloud migration deployment models:
1):- Public Cloud
In a public cloud model, your data, applications, and workloads are hosted on shared infrastructure managed by a cloud provider such as AWS, Microsoft Azure, or Google Cloud.
This is one of the most popular options because it offers high scalability, lower upfront costs, and flexible pay-as-you-go pricing.
2):- Private Cloud
A private cloud is dedicated to a single business or organization. It offers more control over data, security, and compliance.
This model is often preferred by industries that handle sensitive data, such as healthcare, finance, or legal services.
3):- Hybrid Cloud
A hybrid cloud combines both on-premise infrastructure and cloud-based resources.
