CSP: Cloud Service Provider
Organization that provides cloud computing services
Cloud Computing Benefits
- On-demand self-service: Client can make changes without tech support
- Universal client support: Almost any networked device can access cloud computing resources
- Invisible resource pooling: Physical and virtual computing resources are pooled to serve multiple simultaneous consumers; the customer has no need, control, or knowledge of the physical location of resources
- Immediate elasticity: Increase or decrease resources quickly to meet demands
- Metered services: pay for only what you use
Cloud Savings
- Elasticity and scalability: Use only what you need – scale up and down as needed
- Pay-per-use: Only pay for what you use
- On demand: No need to purchase hardware or software; just scale up cloud services as needed
- Resiliency: The CSP can migrate hardware or software resources to other resources without user knowledge; the user does not need to have extra idle capacity on hand to provide resiliency because the CSP does
Types of clouds
- Public cloud: Services and infrastructure are offered to all users with access provided via the Internet
- Community cloud: Open only to specific organizations with common concerns
- Private cloud: Created and maintained on a private network; this provides the most security and control but reduces cost savings
- Hybrid cloud: A combination of public and private clouds
- Multi-cloud: Combine services from various CSPs
Location
- On-premises: Resources located on the campus of organization
- Off-premises: Resource is hosted and supported by a third party
- Fog: Decentralized computing infrastructure in which data, compute capabilities, storage, and applications are located between the data source and the cloud
- Edge: Computing that is performed at or very near the source of data instead of relying on the cloud or on-prem for processing
- Cloud: Remote facility for computing
Cloud Architecture
- Thin client: A computer that runs from resources stored on a central cloud server instead of a local hard drive
- Transit gateway: This is an AWS technology that lets organizations connect VPC: virtual private clouds, physical data centers, remote offices, and remote gateways into a single managed source
- Serverless infrastructure: Capacity planning, installation, setup, and management are invisible to the user because the CSP handles them
