MODULE 1: CLOUD COMPUTING BASICS (What is cloud computing) Part 2

What I learned from this TOPIC.

1. Definition and Types: Cloud computing refers to the delivery of computing services over the internet. It includes public, private, and hybrid clouds, each serving different needs based on access, control, and security requirements.

2. How It Works: Cloud computing involves front-end (client devices) and back-end (servers, databases) components connected via the internet. It utilizes virtualization and automation for efficient resource management and provisioning.

3. Service Models: There are three primary service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), each offering different levels of control and management for users.

4. Deployment Models: Cloud deployment can be private, public, hybrid, or multi-cloud, each tailored to specific organizational needs for scalability, security, and flexibility.

5. Characteristics and Benefits: Key features include on-demand self-service, scalability, pay-per-use pricing, and broad network access. Benefits include cost savings, data mobility, business continuity, speed, agility, and environmental sustainability.

6. Challenges: Challenges include security concerns, unpredictable costs, expertise gaps, governance issues, compliance complexities, and potential vendor lock-in.

7. Examples and Use Cases: Cloud computing supports various applications like Google Docs, AWS Lambda for serverless computing, Salesforce for CRM, and IoT data processing, among others.

8. Evolution and Future Trends: The history of cloud computing dates back decades, evolving from mainframes to today's diverse cloud services. Future trends include increased adoption of AI, machine learning, serverless computing, and enhanced integration with emerging technologies like blockchain.

Understanding these points has equipped me with a comprehensive overview of cloud computing, its applications, benefits, challenges, and future directions in technology and business.
