Migration & Cloud — frequently asked questions
Should we lift-and-shift or re-architect for the cloud?
Lift-and-shift is fastest and lowest-risk when you need to exit a data centre quickly; re-architecting (cloud-native) costs more up front but unlocks autoscaling, lower run-cost and resilience. Many teams lift-and-shift first, then modernize the highest-value services.
Which cloud is best — AWS, Azure or Google Cloud?
All three are excellent; the right choice usually comes down to your existing stack, team skills and licensing. .NET-heavy shops often lean Azure, AWS has the broadest service catalogue, and Google Cloud is strong on data and AI. We help you decide on facts, not fashion.
Can you migrate our database without downtime?
Usually yes — with replication, dual-writes and a staged cutover, most migrations happen with little or no downtime. The exact plan depends on data volume, acceptable lag and how the application reads and writes.
