**Cloud Computing Concepts Explained**

Understanding key concepts in cloud computing is essential for businesses and individuals looking to leverage technology. Recently, a post on Dev.to broke down five critical terms: virtualization, scalability, agility, high availability, fault tolerance, global reach, scalability, elasticity, and templates.

Virtualization allows multiple operating systems to run on one physical machine, reducing costs and increasing resource efficiency. Scalability refers to adding resources to handle increased demand, while elasticity goes a step further by automatically adjusting resources as needed. High availability ensures continuous operation with backup systems in place, and fault tolerance provides a safety net in case of system failures.

Global reach enables services and applications to be used worldwide through a network of data centers. These concepts are crucial for creating efficient and reliable tech systems that can adapt to changing demands.
