Introduction

Choosing between AWS (Amazon Web Services) and Microsoft Azure is a critical decision for businesses migrating to the cloud. Both platforms offer powerful features, but which one fits your needs?

In this blog, we compare AWS and Azure across cost, performance, security, and use cases—helping you make an informed decision. Plus, discover how LearnBuild's cloud experts can guide your migration.

1. Market Share & Adoption

  • AWS (33% market share): The pioneer, preferred by startups and enterprises for its vast service catalog.
  • Azure (22% market share): Growing fast, especially among Microsoft-centric businesses.
