    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
