What is Cloud Computing? 

Cloud Computing is the delivery of online services like servers, databases, and software directly to users. Instead of relying on local storage, Cloud Computing allows you to store and access data from remote servers, offering the flexibility to retrieve information from anywhere globally. This innovative technology eliminates the need for on-site hardware, making data management more efficient and accessible wherever you are.

 

What is AWS? 

AWS (Amazon Web Services) is a comprehensive, evolving Cloud Computing platform provided by Amazon. It includes a mixture of infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS) and packaged software-as-a-service (SaaS) offerings. AWS offers tools such as compute power, database storage and content delivery services.

Amazon.com Web Services launched its first web services in 2002 from the internal infrastructure that the company built to handle its online retail operations. In 2006, it began offering its defining IaaS services. AWS was one of the first companies to introduce a pay-as-you-go Cloud Computing model that scales to provide users with compute, storage and throughput as needed.

AWS offers many different tools and products for enterprises and software developers in 245 countries and territories. Government agencies, education institutions, nonprofits and private organisations use AWS services.

History of AWS 

AWS launched in 2002 with a few basic services, evolving rapidly over the years. In 2003, Amazon transformed the platform to standardise and automate its computing infrastructure, focusing on web services and offering virtual servers as a service. By 2004, AWS debuted its first service, Amazon SQS, marking the start of its cloud journey.

In 2006, AWS relaunched with Amazon S3, SQS, and EC2, solidifying its position as a comprehensive suite of core online services. As AWS grew, it expanded S3 and EC2 into Europe in 2009 and introduced Elastic Block Store and Amazon CloudFront. The platform added certifications in 2013 and launched autoscaling in 2018 to enhance resource management.

In 2022, AWS introduced over 110 new features, including AWS CodeCatalyst for app development and AWS Application Composer, a low-code tool for serverless apps. Other highlights included AWS Security Lake, AWS VPC Lattice for enhanced network management, and AWS Supply Chain for streamlined planning.

Today, AWS offers over 200 services, supported by a global network of data centres. With its continuous expansion and commitment to innovation, AWS remains a leading choice for businesses embracing the cloud.
