Components

CAS contains the following components:

• Cloud Virtualization Kernel (CVK)

CVK isolates the guest operating systems (OSs) and applications on virtual machines (VMs) from the underlying hardware. The guest OSs accesses the infrastructure through CVK without having to concern about the varieties and complexities in hardware. CVK is essential to the performance of CAS in hardware compatibility, high reliability, scalability, and performance optimization in a virtual environment.

• Cloud Virtualization Manager (CVM)

CVM provides virtualization of computing, network, and storage resources in the data center as well as automated services for upper layer applications. CVM provides the following services:

• Virtual computing, networks, and storage.

• High availability.

• Dynamic resource scheduling (DRS).

• VM backup and disaster recovery.

• VM template management.

• Cluster file system.

• Virtual switch (vSwitch) policies.

• Cloud Intelligence Center (CIC)

CIC provides pooling of infrastructure resources (including computing, networks, and storage) and policies and orchestrates the resources to fulfill user application tasks. You can use CIC to build a secure hybrid cloud on which tenants can subscribe to resources on demand. CIC provides the following services:

• Organization-based virtual data centers.

• Data and business service for multitenancy.

• Cloud service workflows.

• Self-service portal.

• OpenStack-compatible RESTful APIs.

• SSV self-service portal

SSV provides business-centric IT as a service (ITaaS). Users can subscribe to cloud hosts, hardware, and networks as needed by using a cloud service workflow, and then access the cloud hosts assigned to them through a remote connection protocol such as RDP or VNC.

ARM hosts do not support CIC or SSV components.
