  • User-friendly nature: AWS comes with a user-friendly programming model that can provide quick and secure access to data. Users can modify their data at their convenience. Starting with AWS as a cloud provider is much easier for most companies than using other providers.
  • Flexibility: Many companies prefer AWS because of its flexibility. It allows organizations to select the operating system, programming language, web application platform, database and other required services. They can also build a virtual environment by setting up preferable operating systems and applications. AWS can also ease the migration process and allow organizations to work on new solutions simultaneously.
  • Security: This is one of the best benefits of AWS cloud computing and follows different layers of data surveillance for the purpose. AWS utilizes an end-to-end approach for securing and hardening the infrastructure (physical, operational and software). As a result, companies don’t need to worry about confidentiality and can focus on business development.
  • Cost-effectiveness: When using AWS, companies need to pay only for the tools and services they are using, thanks to the pay-as-you-go pricing method. This makes the AWS services unique and cheaper than the traditional computing method. Moreover, it is a no-commitment service. So, you can start or stop using it anytime without much hassle.
  • Reliability: Amazon is a trustworthy name among its customers and clients all around the world. AWS carries out its tasks accurately when required, and most of its services can automatically recover from failure.
  • Scalability and elasticity: With tools like AWS Auto Scaling and Elastic Load Balancing, a particular application of an enterprise can scale up or down based on demand. Spinning up new servers is easy at AWS, and organizations can add more servers and start using them in minutes.

What are the challenges of using AWS?

On the flip side, there are a few disadvantages of using AWS. The limitations regarding Amazon EC2 and security are the most common ones. Companies using AWS have default resources to use. However, the default resource limits vary from region to region. Many companies see this as a challenge.

AWS is the latest invention with complex infrastructure, with only a few professionals skilled in it. This lack of expertise in the market puts AWS in a disadvantageous position. Another limitation is the price variation. AWS comes with supportive paid packages for immediate response, which users might have to pay extra money for.

Lastly comes the general cloud computing issues, like unplanned downtime or inadequate backup protection, that arise during cloud migration. There is a common misconception when backing up data to a cloud server like AWS that the cloud provider will be responsible for data safety. However, it follows the shared responsibility model, which means a reliable backup and recovery solution is required to safeguard AWS data.
