What is the difference between Azure and AWS?

Amazon Web Services (AWS) and Microsoft Azure are two of the biggest names in public cloud computing. For example, if an organization is in need of a strong Platform-as-a-service (PaaS) provider or needs Windows integration, Azure would be the preferable choice while if an enterprise is looking for infrastructure-as-a-service (IaaS ) or diverse set of tools then AWS might be the best solution.

In this particular blog we will going to discuss about the differences between AWS and Azure, taking a look on various aspect, and then we see for better choice?

What is Azure?

Azureis the primary interface for managing apps, services and solutions commissioned on the Azure platform. This feature-rich web application allows you to interact with Azure services through a rich web-based interface, building, managing, and monitoring everything from simple web apps to complex cloud applications in a single, unified console.

Advantages of Azure

Here are some advantages of adopting Azure cloud services:

  • Capability for developers and users to create, maintain and deploy applications
  • Fully scalable cloud computing platform offers open access across multiple languages, frameworks, and tools
  • Total support for Microsoft legacy apps
  • Support for mixed Linux/Windows environments
  • Offers inbuilt tool like Azure stack to help the organization deliver Azure service from the own data centre.

What is AWS?

Amazon Web Services (AWS) is a secure cloud services platform, offering compute power, database storage, content delivery and other functionality to help businesses scale and grow. It is a subsidiary of Amazon providing on-demand cloud computing platforms.

Advantages of Azure

Here are some advantages of AWS cloud services:

  • Compute Cloud allows you to increase or decrease storage according to the need of your organization
  • AWS enables you to select an operating system, programming language, database of your choice
  • Robust partner ecosystem
  • Broad & deep service offerings
  • High Transfer Stability
  • Offers more data centres for availability and low latency
  • Stronger support for Bl and analytics
  • Better DevOps support

Conclusion

Comparing Azure and AWS is extremely difficult as both continue to launch new pricing structures, new products, and new integrations. Microsoft Azure has increased its market share in the last couple of years, but not to an extent where there is a real contest between the two companies at least for the near future.

 The decision to choose either of the platforms depends on the needs of organizations how AWS vs Azure comparison meets those requirements.

 Therefore, the final selection will be depend on the need of your organization.
