Study Notes
Cloud Computing
- The use of computing resources (hardware and software) delivered as a service over a network, typically the Internet.
- Cloud computing entrusts off-site, remote services with a user's data, software, and computation.
- Relies on shared resources to achieve economies of scale similar to a utility such as the electrical grid.
Shared Resources
- Include CPU (processing power), Memory (RAM), Storage (disk space), and Network (capacity and speed).
- These resources can be used separately or as part of an application that uses or runs on the cloud.
- The client has no knowledge of how or where their data is stored but they gain increased availability, capability, scalability, and robustness.
Cloud Deployment Models:
- Private Cloud: Owned, managed, and accessed only by one organization.
- Public Cloud: Available for use by the general public.
- Hybrid Cloud: A combination of public and private clouds.
- Community Cloud: Shared by two or several organizations.
Cloud Service Models:
- Software as a Service (SaaS): An application with a user interface on the web, e.g., Gmail, Google Docs.
- Platform as a Service (PaaS): Clients place their applications on provided servers, hard drives, operating systems, and network connections, along with development and management tools, e.g., Windows Azure.
- Infrastructure as a Service (IaaS): Providers supply machines, storage, and network resources that the client configures and manages, e.g., OpenStack, Rackspace Cloud, Amazon AWS.
Cloud Computing Definition
- Cloud computing leverages shared resources, including processing power, memory, storage, and network capabilities.
- Resources are delivered as a service over a network, typically the internet.
- Cloud computing relies on sharing resources for efficiency and economies of scale, similar to a utility like the electricity grid.
Cloud Deployment Models
- Private Cloud: Exclusively owned, managed, and accessed by a single organization.
- Public Cloud: Available for use by the general public.
- Hybrid Cloud: Combines features of both private and public clouds.
- Community Cloud: Shared by two or more organizations.
Cloud Service Models
-
Software as a Service (SaaS): Provides applications with user interfaces accessible on the web. Popular examples include Gmail and Google Docs.
-
Platform as a Service (PaaS): Allows clients to deploy applications onto servers, storage, operating systems, and network connections. Typically includes development and management tools. Windows Azure is an example of a PaaS platform.
-
Infrastructure as a Service (IaaS): Offers fundamental computing resources like machines, storage, and network components, which clients can configure and manage. Examples include OpenStack, Rackspace Cloud, and Amazon AWS.
