Differences: AWS Vs Other Cloud models

The first key difference between AWS and other IT models is flexibility. Using traditional models to deliver IT solutions often requires large investments in new architectures, programming languages, and operating systems.

Why AWS is Superior

Although these investments are valuable, the time that it takes to adapt to new technologies can also slow down your business and prevent you from quickly responding to changing markets and opportunities.

When the opportunity to innovate arises, you want to be able to move quickly and not always have to support legacy infrastructure and applications or deal with protracted procurement processes.

Flexibility

In contrast, the flexibility of AWS allows you to keep the programming models, languages, and operating systems that you are already using or choose others that are better suited for their project.

Easy to Learn

You don’t have to learn new skills. Flexibility means that migrating legacy applications to the cloud is easy and cost-effective. Instead of re-writing applications, you can easily move them to the AWS cloud and tap into advanced computing capabilities.

Support

Building applications on AWS are very much like building applications using existing hardware resources. Since AWS provides a flexible, virtual IT infrastructure, you can use the services together as a platform or separately for specific needs. AWS run almost anything—from full web applications to batch processing to offsite data back-ups.

Integration

In addition, you can move existing SOA-based solutions to the cloud by migrating discrete components of legacy applications. 

Typically, these components benefit from high availability and scalability, or they are self-contained applications with few internal dependencies. Larger organizations typically run in a hybrid mode where pieces of the application run in their data center and other portions run in the cloud.

Summary

Once these organizations gain experience with the cloud, they begin transitioning more of their projects to the cloud, and they begin to appreciate many of the benefits outlined in this document. Ultimately, many organizations see the unique advantages of the cloud and AWS and make it a permanent part of their IT mix
