Extra info for Apache CloudStack cloud computing
Orchestration Engine: The orchestration engine is critical to the CloudStack deployment and is used for configuring, provisioning and scheduling any operations. After the request or command is processed by the business logic, the request is passed to the orchestration engine for processing. The orchestration engine is responsible for performing that action, for example provisioning virtual machine and configuring them, allocating storage and so on. Controllers: The controllers are basic underlying parts of the CloudStack management server that talks to the underlying hypervisor or hardware for compute, network, and storage resources.
With NFS storage, CloudStack manages the over provisioning of storage independent of the hypervisor. The primary storage can also be a pool of local storage in case of vSphere, XenServer, OVM, and KVM. CloudStack supports multiple primary storage pools in a cluster. It also supports dynamic addition of storage servers as your requirements increase. As primary storage is a critical component, its capacity must be monitored by the administrator and additional storage space must be attached to it when needed.
Hence these types of switches are used above layer-3 switches or above a cluster of servers in the environment. Layer-3 traffic isolation provides traffic isolation across layer-3 devices. It's referred to as Virtual Routing and Forwarding (VRF). It virtualizes the routing table in a layer-3 switch and has set of virtualized tables for routing. Each table has a unique set of forwarding entries. Whenever traffic enters, it is forwarded using the routing table associated with the same VRF. It enables logical isolation of traffic as it crosses a common physical network infrastructure.
