What should a company consider before moving to AWS?

Get clear on why you're actually moving

"We should be on the cloud" is not, by itself, a reason. The businesses that get real value from AWS usually have a specific problem it solves: their current server can't handle traffic spikes, they need infrastructure in multiple regions, they want to stop managing physical hardware, or they need to scale up and down quickly without over-provisioning. If none of these apply and the current setup is stable and meets its needs, migrating for its own sake often adds cost and complexity without a matching benefit.

It's worth writing down the specific problem AWS is meant to solve before evaluating anything else. That problem statement becomes the test for whether the migration actually succeeded.

Cost is not simpler than what you have now

A common assumption is that cloud infrastructure is automatically cheaper than a traditional server. It can be—but only when it's configured and managed well. AWS's pricing model charges for what you use, which means costs can grow unpredictably if resources aren't monitored, or if things like data transfer, storage, and backups aren't accounted for upfront. Businesses that move to AWS without a clear cost plan sometimes end up paying more than their previous setup, not less.

A realistic cost comparison should include the AWS bill itself, the cost of the expertise needed to manage it properly, and a buffer for the learning period where usage—and cost—tends to run higher than expected.

Questions worth answering before migrating

A short readiness check tends to catch the issues that cause migrations to stall or run over budget:

• Do we have (or are we hiring/contracting) the skills to manage AWS properly, not just set it up once?
• Have we estimated ongoing monthly cost, not just the migration cost?
• Is our application actually built in a way that benefits from cloud scaling, or will it just run the same way on more expensive infrastructure?
• What's our plan for monitoring, alerting, and responding when something breaks?
• Do we have a rollback plan if the migration runs into serious problems?
• Who is responsible for security configuration, and do they understand AWS's shared responsibility model?

Complexity is the real cost, not just money

AWS gives you enormous flexibility—which also means enormous surface area for misconfiguration. Poorly secured storage, overly permissive access controls, and unmonitored spend are common, well-documented problems, not edge cases. None of this makes AWS a poor choice; it means the flexibility has to be matched with either in-house expertise or a partner who has managed cloud infrastructure before, not treated as a plug-and-play upgrade from a traditional server.

A more cautious path in, if you're not sure

Migrating everything at once is rarely necessary and often risky. A more manageable approach is to move one component at a time—starting with something lower-risk, like static assets or a non-critical service—learning how cost and performance actually behave in practice, and using that experience to plan the migration of anything more critical. This also gives the team time to build real operational familiarity with AWS before the business depends on it fully.
