The Cloud (The Ghost in Bare Metal)
Single pane of Glass
A single pane of glass is a management console for the Cloud that presents data from multiple sources in a unified display. The glass, in this case, is a computer monitor or mobile device screen.
Cloud services need orchestration in order to work. Cloud orchestration uses service, workload and resource orchestration to do the following:
- provision, deploy or start servers
- acquire and assign storage capacity
- manage networking
- create VMs
- gain access to specific software on cloud services
These are three main categories of cloud services:
Software as a service (SaaS) is a software delivery method where by a third-party provider hosts applications and makes them available to customers over the Internet. SaaS dependent on PaaS.
Platform as a Service (PaaS) is an optimized environment in which users can install applications and data sets. PaaS dependent on IaaS.
Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet and depends on virtualization technology like VMware's vCenter Server & Microsoft's Azure.
