Study Notes
Cloud Computing
Infrastructure as a Service (IaaS)
- Provides virtualized computing resources over the internet
- Users have full control over infrastructure, but not the underlying hardware
- Resources can be scaled up or down as needed
- Examples: Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP)
Platform as a Service (PaaS)
- Provides a complete platform for developing, running, and managing applications
- Users have control over applications and data, but not the underlying infrastructure
- Resources can be scaled up or down as needed
- Examples: Heroku, Google App Engine, Microsoft Azure App Service
Software as a Service (SaaS)
- Provides software applications over the internet, eliminating the need for local installation
- Users have no control over the underlying infrastructure or application management
- Examples: Microsoft Office 365, Salesforce, Dropbox
Cloud Migration
- The process of moving applications, data, or other business elements to the cloud
- Reasons for migration:
- Cost savings
- Increased scalability and flexibility
- Enhanced collaboration and accessibility
- Improved disaster recovery and business continuity
- Types of migration:
- Lift and Shift (rehosting): migrate applications without changes
- Re-platforming: migrate applications with minimal changes
- Refactoring: rewrite applications to take advantage of cloud-native features
Cloud Security
- Concerns and threats:
- Data breaches and unauthorized access
- Insufficient identity and access management
- Inadequate encryption and data protection
- Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks
- Security measures:
- Identity and Access Management (IAM)
- Encryption and data protection
- Network security and firewalls
- Compliance and auditing
- Incident response and disaster recovery planning
