Having your own Cloud: Private vs. Public
Hosts only your enterprise, and none other. Your enterprise owns your Cloud.
Hosts multiple customers, possibly on multiple operating systems.
Three generally-accepted private Cloud architectures
(Adapted from resources.idgenterprise.com/original/AST- 0112091_IDC_Selecting_the_Optimal_Path_to_Private_Cloud.pdf)
Integrated infrastructure system
Purchase a preconfigured, ready-to-deploy infrastructure, typically including:
- Blade server chassis
- Network fabric manager
- Virtualized storage systems
- Hypervisor, a/k/a virtual machine monitor
- IT automation software
Advantage: Deploy a ready-to-run preconfigured infrastructure tuned together for high performance across multiple workloads, rather than deploying elements individually.
Follow a tested, validated design blueprint for building a complete system:
- Provides guidance on layout size and deployment for each component.
- Offers more flexibility in the components that make up the solution.
- Does not provide integrated, seamless support across elements from multiple vendors.
"Build your own"
Construct infrastructure by:
- Selecting, acquiring, and configuring separate server, storage, network, and system software elements.
- Assembling these technologies onsite.
- The customer is responsible for everything.
