Cloud Computing - Coggle Diagram

- - - - A customer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider
    - - Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms
    - - The provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. There is a sense of location independence int that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction
    - - Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. To customer the capabilities available often appear to be unlimited and can be apropriated in any quantity at any time
    - - Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropiate 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
  - - - The capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through either a thin client interface, such as a web browser (e.g., web-based email), or a program interface. The consumer does not manage or control the underlying cloud infraestructure including network, servers, operating systems, storage, or even individual application capabilities, with the posible exception of limited user-specific applications configuration settings
    - - The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages, libraries, services, and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including network, servers operating systems, or storge, but has control over the deployed applications and possibly configuraction settings for the applications-hosting environment
      - This model need consider in the stack service the "custom environment" as access for customer over Operating System
    - - The capability provided to the customer is to provision processing, storage, networks, and other fundamental computing resources where the comsumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage and deployed applications: and posibility limited control of select networking components (e.g., host firewall)
      - Services
        
        VM in shared server
        
        VM in dedicated server
        
        Dedicated bare-metal servers
      - Backup
        -The cloud provider will not automatically back up your data
        -Data should always be backed up to an offsite location
      - Disaster Recovery
        -Recovery Point Objetive (RPO) Métrica de tolerancia de pérdida de datos por un incidente en el peor escenario
        -RTO Métrica del tiempo máximo tolerado para la recuperación de las operaciones despues de un incidente
    - - Facility
      - Network
      - Storage
      - Compute
      - Hypervisor
      - Operating System
      - Application
      - Data
      - *Custom Environment (for PaaS model)
    - - Other as a Service
      - DaaS Desktop as a Service
      - DRaaS (Disaster Recovery)
      - BaaS (Backup)
  - - - The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units). It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off premises
    - - The cloud infrastructure is provisioned for exclusive use by a community of consumers from organizations that have shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be owned, managed and operated by one or more of the organizations in the community, a third party, or some combinations of them, and it may exist on or off premises
    - - The cloud infrastructure is provisioned for open use by the general public. It may be owned, managed, and operated by a business, academic, or government organization, or some combination of them. It exist on the premises of the cloud provider
    - - The cloud infrastructure is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).
- - - - Type 1 run directly on the system hardware
      - Type 2 Hypervisors run on top of a host operating system
