Cloud migration

Migrating to the cloud offers significant advantages, such as on-demand scalability, provider-managed services, and global accessibility.

However, it also introduces new challenges. The way these challenges are handled can determine whether the migration is a success or a setback. Additionally, the switchover itself requires specialized expertise to execute smoothly. With experience gained from multiple cloud migrations, we are well-prepared to guide you through this process.

Our typical approach involves the following steps:

• Establishing the End Goal: We need to ensure that cloud migration is truly what you need and determine whether all of your goals can be achieved through the migration alone.
• Infrastructure Design: We need to design how the new infrastructure will look, which is a process we’ve described LINK. As part of this process, we’ll help you decide on the most suitable cloud provider.
• Migration Procedure Design: The migration process is rarely straightforward, especially when it requires minimal to no downtime—a challenge that becomes even more complex with multiple databases and storage systems involved. To ensure a seamless transition, we design and document the migration procedure in advance, implementing robust safeguards. These include the ability to revert the migration at any stage if issues arise and comprehensive monitoring to verify performance and data integrity throughout the process.
• Implementation of the New Infrastructure: At this stage we implement the infrastructure following the principles outlined in LINK. Depending on circumstances, this process may entail changes to your software. At the end of this stage you will have two fully functional environments in the cloud: a staging environment and what will become your new production environment.
• Testing: Before migrating anything, we need to ensure that the new environments function correctly and efficiently under load. Additionally, since the migration often involves a transitional state where your infrastructure spans two providers, we must verify performance in this scenario as well. This step also includes testing the migration procedure itself, including potential rollbacks, to account for unexpected situations.
• The Migration: This is the stage where we perform the switchover. It is typically preceded by preparations such as code freezes and disabling non-essential services, which can extend the process to several days.
• Stabilization and Cleanup: After the migration, the new infrastructure requires close attention to ensure everything is functioning as expected. Additionally, temporary measures introduced during the migration process need to be identified and cleaned up. Once this step is completed, the migration is officially finished.
