Overview
Cloud computing is revolutionizing the way businesses operate, enabling flexibility, scalability, and cost efficiency. Amazon Web Services (AWS), a leader in this space, offers a comprehensive platform that caters to startups, enterprises, and individuals alike. This module provides an introduction to AWS and lays the groundwork for understanding its significance in the modern digital landscape.
What is Cloud Computing?
Cloud computing refers to the on-demand delivery of IT resources over the internet with pay-as-you-go pricing. Instead of owning and maintaining physical data centers and servers, organizations can access technology services, such as computing power, storage, and databases, on an as-needed basis.
Why is Cloud Computing Important?
Cost Efficiency: Eliminates the need for significant upfront investments in hardware.
Scalability: Scale resources up or down based on demand.
Global Reach: Deploy applications and services across multiple geographic locations.
Flexibility: Support for a wide range of operating systems and programming languages.
Innovation: Focus on building products without worrying about infrastructure management.
