Map the service before selecting a region
An Italian business moving an application to cloud infrastructure should start with its actual dependencies: domain and DNS, web server, runtime version, database, file uploads, scheduled jobs, mail and third-party APIs. Name the owner of each component and document which processes can continue during the migration window.
Compare target regions using user latency, required services, backup location, cost and contractual requirements. AWS describes how regions and availability zones relate to geographic infrastructure. A nearby region does not automatically satisfy every privacy or sector requirement; check the applicable contracts and rules with your advisers.
Rehearse the cutover
Create the target environment and test it using representative, appropriately protected data. Check runtime compatibility, DNS records, certificates, file permissions, background workers and outbound email. Measure the time needed for a database copy and plan how changes made during the copy will be handled.
Agree a specific migration window and a decision owner. Before switching traffic, verify application health, database freshness, monitoring and support contacts. Document which checks must pass before old infrastructure is retired.
Define when rollback is still safe
Traffic can sometimes return to the previous server, but data created after cutover may not automatically follow it. Decide how new orders, uploads and queued tasks will be reconciled. Agree a rollback cutoff, the evidence used for the decision and who can authorize it. Do not delete the old system until backups and the recovery plan have been verified.
Compare migration proposals
Ask for the dependency inventory, test results, downtime assumptions, database and DNS ownership, cloud charges and post-cutover support window. Clouvenix can scope cloud migration services around the application and the customer’s agreed acceptance checks.
