AWS: Migration, Management, and Optimization of Your Amazon Web Services Cloud

Amazon Web Services is the world's most widely used cloud platform, with a catalog of services covering computing (EC2), storage (S3), databases (RDS, DynamoDB), networking, security, and artificial intelligence. This wealth of features is also what makes AWS difficult to get started with: choosing the right services, configuring them correctly, and managing costs requires specialized expertise.

IT Systèmes supports small and medium-sized businesses and mid-market companies throughout the entire lifecycle of their AWS environment: project scoping, migration from an on-premises environment or another cloud, day-to-day administration, and ongoing performance and cost optimization.

Frequently Asked Questions About Amazon Web Services (AWS)

How much does it cost to migrate to AWS?

The cost of migrating to AWS depends on the scope of the project: the number of servers and applications to be migrated, the volume of data, the complexity of the target architecture, and the duration of the support. An initial audit allows us to provide an accurate cost estimate tailored to your infrastructure before you commit to the project.

What is the difference between AWS and Azure?

AWS and Microsoft Azure are the two leading public cloud platforms, with broadly comparable service catalogs (compute, storage, databases, AI). Azure integrates more naturally into an environment already built around Microsoft 365 and Active Directory, while AWS is often chosen for its maturity and the richness of its ecosystem for certain specific use cases. The right choice depends on your existing technical infrastructure and your priorities.

Is AWS suitable for small and medium-sized businesses?

Yes. AWS's pay-as-you-go pricing model allows you to get started without a significant hardware investment and to adjust resources based on the company's actual needs. The key consideration for an SME is to properly define and monitor the environment from the outset to avoid uncontrolled overuse of resources.

How do you secure an AWS environment?

Securing an AWS environment rests on several pillars: rigorous identity and access management (IAM), encryption of data at rest and in transit, appropriate network segmentation, and continuous monitoring to detect abnormal behavior. These best practices must be implemented from the very beginning of the architecture design process—not added as an afterthought.
