    Software as a Service (SaaS)

    A software delivery model where applications are accessed over the internet, managed by the provider, and users access them through a web browser.

    Cloud Computing

    The practice of using computing resources like servers, storage, and networking over the internet, managed by a third-party provider.

    Scalability in Cloud Computing

    A major benefit of cloud computing, allowing users to easily scale resources up or down as needed, adapting to changing demands.

    Vendor Lock-in in Cloud Computing

    A potential concern with cloud computing, where relying heavily on a single provider can limit flexibility and control.

    Study Notes

    ICT, Online Services, and the Cloud

    • ICT (Information and Communication Technology) encompasses various technologies used to store, retrieve, transmit, and manipulate information. It includes hardware, software, and networks.

    • Online services are applications or resources accessible over the internet. Common examples include email, social media, online banking, and e-commerce platforms. These services rely heavily on ICT infrastructure.

    • Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services). This pool of resources can be rapidly provisioned and released with minimal management effort or service provider interaction.

    Key Characteristics of Cloud Computing

    • On-demand self-service: Users can provision computing capabilities as needed without requiring human interaction with each service provider.
    • Broad network access: Capabilities are available over the network and accessed through various platforms (e.g., thin or thick clients, mobile phones, tablets, and workstations).
    • Resource pooling: The provider's computing resources are pooled to serve multiple consumers using a multi-tenant model. Different physical and virtual resources are dynamically assigned and reassigned according to consumer demand.
    • Rapid elasticity: Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward or inward according to demand. This often results in a perceived unlimited resource capacity.
    • Measured service: Cloud systems automatically control and optimize resource use by employing a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.

    Different Types of Cloud Services

    • Infrastructure as a Service (IaaS): Provides basic computing resources (servers, storage, networking) over the internet. Users have considerable control over the operating systems, storage, deployed applications, and even some networking components.
    • Platform as a Service (PaaS): Supplies a platform for developing, running, and managing applications. Users do not manage the underlying infrastructure (servers, operating systems, or networks) but have control over deployed applications and possibly configuration settings for the environment.
    • Software as a Service (SaaS): Delivers software applications over the internet. Users do not manage the underlying infrastructure (servers, operating systems, or network devices). Users typically access the application via a web browser.

    Benefits of Cloud Computing

    • Cost savings: Reduced capital expenditure on hardware and software.
    • Scalability: Easily adjust resources up or down as needed.
    • Accessibility: Access resources from anywhere with an internet connection.
    • Reliability: Cloud providers often have redundant infrastructure.
    • Efficiency: Automation and streamlined processes reduce operational costs.

    Security Concerns in Cloud Computing

    • Data security and privacy are critical issues. Data stored or processed in the cloud needs proper protection against unauthorized access.

    • Ensuring appropriate access controls and encryption for data is essential.

    • Vendor lock-in and dependency on the cloud provider can be a consideration.

    • Disaster recovery and business continuity planning are important for cloud environments.

    • Online services are heavily dependent on ICT infrastructure and cloud computing for their functionality. Cloud computing provides a scalable platform to deliver online services, often with cost and efficiency benefits, but security considerations remain important.
