What is Cloud Computing?

Cloud computing is the delivery of online services (such as servers, databases, software) to users. With the help of cloud computing, storing data on local machines is not required. It helps you access data from a remote server. Moreover, it is also used to store and access data from anywhere across the world.

What is AWS?

Amazon web service is an online platform that provides scalable and cost-effective cloud computing solutions.

AWS is a broadly adopted cloud platform that offers several on-demand operations like compute power, database storage, content delivery, etc., to help corporates scale and grow.

How Does it Work?

That was all about what is AWS. Next, let’s have a look at the history.

History of AWS

  • In the year 2002 - AWS services were launched
  • In the year 2006- AWS cloud products were launched
  • In the year 2012 - AWS had its first customer event
  • In the year 2015- AWS achieved $4.6 billion
  • In the year 2016- Surpassed the $10 billion revenue target

2. Global Availability 

AWS has 80 Availability Zones across 25 geographic regions global data centers. 

2. Scalability and Flexibility 

AWS offers unlimited flexibility and scalability on demand. This enables organizations to plan their infrastructure roadmap on a subscription basis without full commitment.

3. Little Investment 

AWS cloud services enable companies to save expenditures on extra software and hardware. There is no physical data required, which ultimately lowers down operating costs. 

Now, that we have understood what is AWS, advantages and application, let us know the AWS services.

AWS Services

Amazon has many services for cloud applications. Let us list down a few key services of the AWS ecosystem and a brief description of how developers use them in their business.

Amazon has a list of services:

  • Compute service
  • Storage
  • Database
  • Networking and delivery of content
  • Security tools
  • Developer tools
