The cloud is actually any service that can be accessed over the Internet. It can include services related to standard business applications such as CRM,ERP , and even extend to technical service areas such as software development and infrastructure, This is a new direction of development of cloud computing.

For example, in addition to virtual servers and storage, PaaSIt also provides a specific operating system and application assembly (usually as a virtual machine, namely a VM, or file, such as VMware's. vmdkFormat), and access to necessary services (such as MySQL databases or other dedicated local resources. In other words, PaaS is IaaS.Add a custom software stack for a given application.

The requirements of different tenants are almost all different. It is natural for each tenant to customize their applications. Traditional SaaS software m

The previous article in this series describes the concept of a composite business service (CBS) and discusses some of the core elements of the deployment environment it needs. This article describes multiple-rent (that is, the ability to provide services to multiple organizations (customers) from a shared public hosting environment). It will also introduce a network delivery method for the software as a service (SOFTWARE-AS-A-SERVICE,SAAS
