    Study Notes

    Introduction to Cloud Computing

    • Cloud computing is the use of online services to access and manipulate data, applications, and infrastructure over the internet.
    • Key features:
      • On-demand resource provisioning and release.
      • Automatic scalability based on demand.
      • Secure network access.
      • Pay-per-use billing based on resource consumption.
    • Popular cloud platforms: AWS, Azure, Google Cloud.

    Traditional vs Cloud Computing

    • Traditional Computing

      • Software is installed locally on computers.
      • Access is through the computer itself.
      • Upgrades are manual and often complex.
      • Multiple code versions require separate maintenance.
      • Hardware must be purchased, maintained, and managed.
      • Collaboration is limited.

    • Cloud Computing

      • Software is delivered as a service over the web.
      • Access is through the internet.
      • Upgrades are automatic and simplified.
      • Single code with no infrastructure maintenance.
      • Pay only for what you use.
      • Enhanced collaboration across locations.

    Characteristics of Cloud Computing

    • On-demand Self Services / Flexibility:

      • Resources like email, applications, network, or server services can be provisioned without human interaction.
      • Suitable for businesses with fluctuating bandwidth demands.

    • Disaster Recovery:

      • Cloud-based backup and recovery solutions offer time savings, reduced upfront investment and access to third-party expertise.

    • Automatic Software Updates:

      • Cloud providers manage software and security updates, eliminating the need for manual intervention.

    • Measured Service / Capital-Expenditure Free:

      • Pay-as-you-go model reduces upfront costs and provides flexibility.
      • Payment is based on actual resource usage.

    • Broad Network Access / Increased Collaboration:

      • Access, edit, and share information from anywhere at any time, enhancing collaboration among teams.

    • Resource Pooling / Document Control:

      • Centralized file storage with real-time updates and shared access for improved document control.

    • Security:

      • Cloud providers offer security measures to protect data stored on their platform.
      • Data is secure even if local systems fail.

    • Environmentally Friendly:

      • Reduced energy consumption by utilizing only the resources needed.

    • Scalability & Rapid Elasticity:

      • Organizations can scale resources up or down quickly to meet demand and manage costs.

    Security in the Cloud

    • Data Breaches:

      • Breaches of cloud services can expose sensitive data to cyber criminals.
      • Scrutinize terms of service regarding data ownership.

    • Hijacking of Accounts:

      • Credentials can be stolen through various online methods.
      • Be aware of "Man In Cloud Attack" where attacker steals user tokens for unauthorized access.

    • Insider Threat:

      • Authorized employees can misuse their access to access sensitive information like customer accounts, financial forms etc.

    • Malware Injection:

      • Malicious code can be injected into applications or infrastructure, compromising security.

    Cloud & Cloud Computing

    • Cloud computing includes manipulating, configuring, and accessing applications over the internet.
    • It combines hardware and software to offer services like online data storage, infrastructure, and applications.
    • Resources are provisioned and released on demand, scaling up or down automatically based on load.
    • Access is facilitated over a network with security measures.
    • Customers are charged based on resource usage.
    • Popular cloud platforms include AWS, Azure, and Google Cloud.
