AWS Tutorial

Serving 190 countries with scalable, reliable, low-cost infrastructure, Amazon Web Services (AWS) powers thousands of businesses across the world. It’s no surprise that AWS takes nearly half of the worldwide public cloud share. 

To put things into perspective, let’s imagine using the Spotify application without a cloud service provider like AWS. What if Spotify ran out of songs to play? This is one of the four major problems that Spotify would face.

Other problems would be:

  • Providing users access to applications from anywhere in the world
  • Cataloging the songs that were released and would soon be released
  • Managing more than 20,000 songs added every day

The solution to all these problems came in the form of Amazon Web Services! AWS offers large storage capacity, proper utilization of resources, and easy scalability.

So, What Exactly is AWS?

Amazon Web Services is a highly available, secure cloud services platform that offers more than 100 cloud applications. Providing a pay-as-you-go system removes the requirement for capital to be provided upfront. It helps in controlling, auditing, and managing identity, configuration, and usage. 

Several companies around the world use AWS’s services, such as Docker, Kellog’s, NASA, McDonald's, BMW, Harvard Medical School, and Adobe, to name a few.

But Why Did AWS Become So Successful? What Makes it So Special?

  1. Security 

    AWS provides a secure and durable platform that offers end-to-end security and storage.
  2. Experience

    The skills and infrastructure management born from Amazon’s many years of experience can be precious.
  3. Flexibility

    It allows users to select the operating systems, language, database, and other services as per their requirements.
  4. Easy to Use 

    AWS lets you host your applications quickly and securely, regardless of whether it’s an existing or new application.
  5. Scalable

    The applications you use can be scaled up or down, depending on your requirements.
  6. Cost Savings

    You only pay for the compute power, storage, and other resources that you use without any long-term commitments.
