Study Notes
Cloud Computing
- Cloud computing is a network or internet-based system
- Cloud computing provides services over public or private networks
- Cloud computing applications include email, web conferencing, and customer relationship management
- Cloud computing enables manipulation, configuration, and access of hardware and software resources remotely
- It offers online data storage, infrastructure, and application resources
- Cloud computing platforms are independent of software, as it's not needed locally on a computer
- Cloud computing is a model for convenient, on-demand network access to configurable computing resources that can be rapidly provisioned and released with minimal management effort
- Benefits include low cost, as users do not need high-powered computers, and unlimited storage capacity, requiring only internet connectivity
Distributed Systems
- A distributed system is a collection of multiple, independent computers that communicate over a network
- These computers work together to achieve a shared goal, sharing resources, data, and tasks
- Common architectures include client-server (servers provide resources, clients request them) and peer-to-peer (each node acts as both client and server)
- Three-tier architecture has layers for presentation, application, and data
- Microservices architecture uses independent services for specific functions, communicating through networks
- Service-oriented architecture (SOA) organizes functions as services, typically with an enterprise service bus (ESB)
- Event-driven architecture uses components that interact through events, triggering specific actions
- Distributed systems have advantages like scalability, reliability, performance, and resource sharing
- Disadvantages include security concerns, the lack of existing software for distributed systems, potential network saturation, and managing databases
- Examples of use cases are financial services, social media, cloud computing
Web 1.0, 2.0, and 3.0
- Web 1.0 was focused on fetching and reading information with few content creators and many consumers
- Web 2.0 was an enhanced social Web, emphasizing reading, writing, creating, and interacting with the end user
- Web 3.0 is the next generation, envisioned as a decentralized web, focused on reading, writing, and owning
- Web 1.0 features include static pages, server-side includes, and common gateway interface (CGI)
- Web 2.0 features include dynamic content, user interaction, and APIs
- Web 3.0 features are envisioned as semantic web and artificial intelligence integration, including natural language processing
