Why Cloud Computing?

• Problem Solved:
  • High upfront costs and operational expenses in traditional IT infrastructure.
  • Limited scalability and flexibility in on-premises setups.
  • Space, management, and security concerns with on-premises data centers.
• Benefits of Cloud Computing:
  • Pay-as-you-go billing model.
  • Reduced space and management needs.
  • Enhanced security and compliance.
  • Improved data recovery capabilities.
  • Easy scalability and updates.
  • Seamless global collaboration.
  • Faster deployment (weeks instead of years).

What is Cloud Computing?

• Definition: Delivery of on-demand computing services over the internet on a pay-as-you-go basis.
• Types of Cloud Computing Models:
  • Deployment Models:
    • Public Cloud: Accessible to anyone, pay for what you use (like public transportation).
    • Private Cloud: Exclusive for a single organization, high upfront cost (like owning a car).
    • Hybrid Cloud: Combines public and private, flexible payment (like renting a car).
  • Service Models:
    • Infrastructure as a Service (IaaS): Basic computing infrastructure.
    • Platform as a Service (PaaS): Platform for application development and deployment.
    • Software as a Service (SaaS): Finished application accessible over the internet.

Major Cloud Providers

• Amazon Web Services (AWS): Offers IaaS, PaaS, SaaS.
• Microsoft Azure: Supports various programming languages and frameworks.
• IBM Cloud: Offers public, private, and hybrid cloud models.
• VMware: Specializes in virtualization.
• Google Cloud Platform: Provides infrastructure and managed tools.
• DigitalOcean: Focused on developers and scaling applications.

Cloud Computing in AWS

• AWS Services: EC2 for compute, S3 for storage.
• Lifecycle of Cloud Computing Solution:
  • Understand requirements.
  • Define hardware (e.g., EC2, Lambda, ECS).
  • Define storage (e.g., S3 for backup, Glacier for archival).
  • Define network and security (VPC, Route 53, IAM).
  • Use management tools (CloudWatch, Auto-scaling, CloudFormation).

Demo: AWS EC2 and S3

1. Create AWS Account: Set up account for access.
2. Create S3 Bucket: Store and retrieve files.
3. Create EC2 Instance: Virtual machine for compute needs.
4. Synchronize S3 and EC2: Use S3 as storage and sync data to EC2.
