Study Notes
Introduction to Cloud Computing
- Cloud computing uses third-party servers to store data.
- It eliminates the need for expensive hardware and database management.
Historical Context
Mainframes and Thin Clients
- Mainframes were large, centralized computers handling all processing tasks.
- Thin clients were simple terminals used to interact with mainframes.
Client-Server Era
- Tasks were shared between individual computers and servers.
- Users could perform basic tasks locally but relied on servers for specific operations, like class registration.
Cloud Computing Advantages
- Data storage and processing are handled externally.
- Enables the Internet of Things (IoT) and smart devices.
- Allows access to data from anywhere with an internet connection.
Key Concepts in Cloud Computing
Definitions
- Cloud Computing: Applications and services running on a distributed network using virtual resources.
- Distributed Network: Multiple users can access and share data.
- Virtualization: Software simulates hardware functions, allowing multiple operating systems on a single machine.
Elastic Leasing
- Elastic: Resources can be dynamically adjusted based on demand to avoid over- or under-provisioning.
- Pooled Resources: Sharing server space reduces costs through economies of scale.
Security in Cloud Computing
- Encryption: Protects communication by encoding messages for authorized users only.
- Firewalls: Limit network access, acting as barriers to unauthorized users.
- Virtual Private Networks (VPNs): Create secure, private connections over public networks, often used for accessing sensitive data remotely.
Types of Cloud Services
Infrastructure as a Service (IaaS)
- Provides basic storage and computational resources with minimal additional features.
Platform as a Service (PaaS)
- Offers a platform for developing, running, and managing applications without infrastructure management.
Software as a Service (SaaS)
- Delivers software applications over the internet, eliminating local installation requirements.
Considerations for Cloud Usage
- Security Concerns: Some industries require in-house data management for security compliance.
- Cost and Scalability: Cloud services offer cost-effective and scalable solutions for businesses.
