What is Cloud Computing? Cloud computing refers to the delivery of computing services over the internet, including storage, servers, databases, networking, software, and analytics. Instead of relying on local servers or personal devices, organizations leverage cloud platforms to access resources on demand. Key characteristics of cloud computing include:
Scalability: Easily scale resources up or down based on requirements.
Cost Efficiency: Pay only for the resources used, reducing infrastructure costs.
Accessibility: Access services from anywhere with an internet connection.
Reliability: High availability and disaster recovery solutions.
Common Cloud Computing Models:
Infrastructure as a Service (IaaS): Virtualized computing resources like servers and storage.
Platform as a Service (PaaS): Development platforms and tools for building applications.
Software as a Service (SaaS): Cloud-hosted applications accessible via a web browser.

What is Edge Computing? Edge computing involves processing data closer to its source, such as IoT devices, sensors, or local servers, rather than relying on centralized data centers. By minimizing the distance data travels, edge computing reduces latency and enhances real-time processing capabilities. Key benefits include:
Reduced Latency: Faster data processing for time-sensitive applications.
Bandwidth Efficiency: Less data transmission to centralized locations reduces bandwidth usage.
Improved Security: Sensitive data can be processed locally, minimizing exposure.
Enhanced Reliability: Operations can continue even with intermittent connectivity.
