    Study Notes

    Introduction to Cloud Computing

    • Cloud computing is a model that provides on-demand access to shared computing resources, such as servers, networks, storage, and applications.
    • These resources are delivered over the internet and can be provisioned and released quickly.
    • Users are only charged for what they use.

    Cloud Computing Course Overview

    • Cloud Computing Stack:

      • Infrastructure as a Service (IaaS)
      • Platform as a Service (PaaS)
      • Software as a Service (SaaS)

    • Deployment Models:

      • Private Cloud
      • Community Cloud
      • Public Cloud
      • Hybrid Cloud

    Service Management in Cloud Computing

    • Service Level Agreements (SLAs):

      • SLAs define the terms of service between a cloud provider and a user.
      • They specify metrics such as uptime, performance, and security.

    • Cloud Economics:

      • Cloud economics involves understanding the costs associated with using cloud services.
      • It includes the costs of storage, bandwidth, and computing resources.

    • Distributed Computing:

      • Tasks are spread across multiple computers.
      • Improves performance, reliability, and robustness.
      • Can be classified into "client-server" and "peer-to-peer" applications.

    • Grid Computing:

      • Uses unused processing power of networked computers to solve complex problems.
      • Creates a virtual supercomputer with high computational power.

    • Cluster Computing:

      • Group of interconnected computers that work together as a single system.
      • Improves performance, reliability, and scalability.

    • Utility Computing:

      • A model where computing resources are provisioned on-demand and paid for based on usage.
      • Similar to utility services such as electricity or water.
      • Allows organizations to access resources as needed without the costs of owning and maintaining their own infrastructure.

    Cloud Computing (NIST Model)

    • Cloud computing is characterized by rapid elasticity, meaning resources can be quickly provisioned and released to meet demand fluctuations.

    Cloud Services Models

    • Software as a Service (SaaS):

      • Users access applications over the internet.
      • Users do not manage the underlying infrastructure.
      • Examples: Google Gmail, Microsoft Office 365.

    • Platform as a Service (PaaS):

      • Users can deploy and manage applications developed using the provider's tools and services.
      • Users do not manage the underlying infrastructure.
      • Examples: Heroku, Google App Engine.

    • Infrastructure as a Service (IaaS):

      • Users rent virtualized computing resources such as servers, storage, and networks.
      • Users have control over the operating system and applications deployed on the virtualized resources.
      • Examples: Amazon Web Services (AWS), Microsoft Azure.

    Cloud Security

    • Infrastructure Security:

      • Protecting the physical and virtual infrastructure of a cloud environment.
      • Includes measures such as firewalls, intrusion detection systems, and vulnerability scanning.

    • Data Security and Storage:

      • Protecting sensitive data stored in the cloud.
      • Includes measures such as encryption, access control, and data backups.

    • Identity and Access Management (IAM):

      • Enables the control and management of user identities and permissions within a cloud environment.
      • It ensures only authorized users can access specific resources and data.

    Key Operational Benefits of Clustering

    • High Availability and Fault Tolerance:

      • Clustering provides redundancy for hardware, operating systems, and applications.
      • This ensures continued operation even if one or more nodes fail.

    • Scalability:

      • Clusters can be easily scaled up or down by adding or removing nodes.
      • This allows for greater flexibility and resource optimization.

    • Performance:

      • Clusters can offer significantly improved performance over single-node systems.
      • This is achieved by distributing tasks across multiple nodes.
