AWS for Business: What to Know Before Migrating

AWS for business is today one of the most widely used cloud infrastructure choices in the world, backed by an extensive service catalog and a global footprint. But that richness can also become a hurdle for a business discovering the platform: where to start, which services to pick, how to keep costs under control? This guide covers the essential basics.

Why businesses choose AWS

AWS first wins businesses over with the maturity of its offering: from long-standing compute and storage services to more advanced building blocks like machine learning or data analytics, the platform covers nearly every infrastructure need. Its presence across many regions of the world also makes it possible to host applications close to end users, an important factor for performance and sometimes for regulatory compliance.

The essential services to know

For a business discovering AWS, a handful of service families cover most use cases: compute (virtual servers and containers), storage (files, databases), networking (secure connections between resources), and identity and access management. Understanding these building blocks, even without mastering every technical detail, makes it possible to have a productive conversation with a consultant and to understand the architecture choices being proposed.

Keeping costs under control on AWS

AWS's usage-based pricing is both an advantage and a trap. An advantage, because it avoids the heavy upfront investment of a physical server; a trap, because poorly sized or forgotten resources left over from a test can generate unexpected bills. Setting up budget alerts and regularly monitoring consumption is essential from the very first weeks of use.

Security and access management

On AWS, security operates on a shared responsibility principle: the provider secures the physical infrastructure, but configuring access, backups, and network rules remains the customer's responsibility. Misconfigured access rights are one of the most common causes of security incidents in the cloud, which makes this step particularly sensitive during a migration.

Migrating to AWS: the main steps

A migration to AWS generally follows a logic similar to any cloud migration: an audit of the existing setup, choosing the right services for each application, testing in an isolated environment, then a gradual cutover. Comparing AWS with other cloud providers, notably Microsoft Azure, is worth doing before committing, a topic we cover in a dedicated article.

Bringing in an AWS consultant

Given the complexity of the AWS catalog, working with an experienced consultant helps avoid architecture choices that are costly to fix later.
