Multi-tenant performance isolation framework based on virtualization technology

Abstract

The invention discloses a multi-tenant performance isolation framework based on a virtualization technology. The isolation framework consists of a performance isolation subsystem, a dynamic resource manager, a virtual machine monitor, a virtual machine and a system resource pool. A method for erecting the isolation framework comprises the following steps: constructing a VM for each tenant by the virtualization technology, wherein the VM defines a boundary of logic resources of the corresponding tenant, and pre-distributing virtual resources for initializing the VM by adopting a virtual resource based on a tenant SLA; then monitoring and managing the service performance of each tenant under a logic isolation state, and controlling a response time boundary of each tenant by an access control mode; and finally, monitoring a service condition of each tenant, and implementing dynamic adjustment on the virtual resources of the tenants and maximization of total resource utilization. The performance isolation among all the tenants can be effectively guaranteed, and the service quality of the multiple tenants can be met; the reasonability of the resource use of all the tenants is realized, and the satisfaction degree of the tenants to the service is improved.

Description

[0001] technical field [0002] The invention relates to the technical field of computer virtualization, in particular to a multi-tenant performance isolation framework based on virtualization technology. Background technique [0003] With the development of the times, new technologies in computer software and hardware emerge in an endless stream. At the same time, the software delivery model is also slowly developing. In the traditional model, customers purchase licenses to use software and install it on the customer's hardware. For software, suppliers provide support based on license agreements or technical support agreements, and with the emergence of new software delivery models, more and more service providers provide customers with specific applications by transitioning their applications to services, At the same time, more and more customers also hope that software can be used on demand in the form of services. The emergence of SaaS services conforms to the current tr...

Problems solved by technology

Multi-tenant technology is very important for SaaS applications, but the current multi-tenant research faces many difficulties: performance isolation between tenants Multi-tenant technology shares resources, so the behavior of one tenant will affect the performance of other tenants Influence, if there is no guarantee of isolation mechanism, it will lead to resource competition among tenants, so how to balance resource sharing and isolation in multi-tenant environment is the difficulty of research in this field

[0006] In a multi-tenant environment, tenants can share hardware resources and a single instance. Applying traditional quality of service management strategies directly to a multi-tenant environment will face many new problems. At the same time, because tenants provide on-demand services, the multi-tenant environment has Dynamicity, service quality management in a multi-tenant environment faces the problems of resource sharing and resource dynamic allocation
