Preparing for Cloud Migration
A company must take significant steps to prepare for cloud migration. Remember that these steps still need to be completed and well-executed.

Cloud migration is a complex process; each company can customize the process to suit its needs.

The Growing Need for Cloud Migration
Cloud migration is gradually becoming a necessity worldwide. The only areas restricted by the cloud are those without an internet connection. However, as remote work trends increase, these restrictions are diminishing. The cloud serves as an online database where all resources are accessible via the internet.

As cloud computing gains popularity, more companies adopt cloud migration. They move their digital assets, databases, and IT resources into cloud databases. Many companies are undergoing digital transformations, and the rise of the Internet of Things encourages them to prepare for migration.

Step 1: Establish Teams and Responsibilities
Before starting cloud migration, companies should inform employees, assign responsibilities, and form teams. A migration manager or principal migration architect leads the effort. This person is responsible for ensuring the migration’s success and making high-level decisions. They need to identify aspects requiring refactoring during the migration.

Each company has unique objectives for cloud migration. The migration architect should understand this to align processes and personnel with the company’s purpose.

The architect must also understand the technicalities of cloud-based migration to make informed decisions.

Step 2: Decide on the Level of Integration
Companies need to determine how much cloud integration works best for them. The two main options are shallow and deep integration.

Shallow Cloud Integration
This approach, also called lift and shift, involves moving the primary on-premises application to the cloud without significant modifications. It is cost-effective and quick. Migration costs decrease, and changes to the cloud infrastructure are minimal.

Deep Cloud Integration
This process involves re-platforming and re-architecting the cloud structure, which is necessary if an application is incompatible with the cloud. Although it takes longer and costs more, this approach makes the application fully functional on the cloud.

Step 3: Choose the Cloud Environment
Selecting the appropriate cloud environment is crucial. Companies typically choose between a single-cloud or multi-cloud setup.

Single Cloud Environment
Opting for a single cloud simplifies migration, as optimizing an application for one provider is easier. However, this may lead to vendor lock-in and higher costs if switching providers becomes necessary.

Multi-Cloud Environment
A multi-cloud setup involves higher initial investments but offers greater flexibility and resilience. Companies can optimize different parts of their applications across multiple cloud providers, such as running a database on one cloud while other components operate on another. This approach allows applications to become cloud-agnostic.

Step 4: Define KPIs and Establish Baselines
Setting clear KPIs and progress baselines helps measure migration success. These metrics reveal areas needing improvement and facilitate refactoring.

The migration manager or architect should monitor KPIs, while everyone involved in the migration should be aware of progress baselines to ensure swift adjustments.

KPIs, including user experience, infrastructure, and business management, should align with the specific application and project goals.

Step 5: Develop a Data Migration Plan
Data migration is the most sensitive step, as it involves transferring data from physical servers to the cloud. To prevent data loss, companies should implement two-way or one-way data syncing.

Once all data transfers successfully, companies can shut down on-site servers. They can gradually switch operations to the cloud by migrating a subset of customers first and then moving remaining users later.

Step 6: Review Cloud Applications
After transferring data, companies should test their applications in the cloud environment. Resource allocation must be monitored to ensure smooth operation and prevent data loss.

This review process enhances control over applications and the overall migration.

Final Thoughts
Preparing for cloud migration requires thoroughness, but it can yield excellent results. Companies must consider various factors—security, cloud costs, and overall benefits—to ensure success.
