Computer cloud composed of four levels

Cloud computing is not recognized by Broadband enthusiasts, and I'll outline a few things cloud computing here, by the way chatting about cloud computing services. Computer cloud service middleware consists of the following four levels:

1 scalable host application pool

InforSuite cloud services middleware bottom, the most basic calculations can be provided by this level, providing the appropriate memory, CPU memory, etc., the host pool is dynamically scalable, as needed with the need to join a new host to enhance the InforSuite cloud Service middleware computing power.

2. Scalable InforSuite virtual service layer

Scalable InforSuite virtual service layer, a large number of InforSuite service nodes running on the InforSuite cloud service middleware platform are called InforSuite cloud nodes. In addition to providing external virtual computing capabilities, such as: virtual memory, virtual CPUs, virtual storage space, and so on, InforSuite virtual services are provided externally. InforSuite virtual services here are logical and users are unaware of InforSuite Service from that physical node. On the basis of InforSuite services, business applications and enterprise-class cloud computing platforms can be deployed and SAAS services can be provided externally.

InforSuite virtual service layer enables multiple InforSuite services to form a virtual InforSuite unit. This unit corresponds to a real cloud application and provides consistent services to external parties. For example, an InforSuite service cluster is constructed to support a certain business service.

3 cloud computing service layer

InforSuite virtual layer is a series of real cloud computing services, such as: flexible computing services, high reliability services, intelligent policy services, cloud resource management. Based on these computing services, enterprise applications, SOA services, and independent software vendors based on InforSuite Cloud Services middleware can provide high-reliability solutions for cloud computing. Typical cloud computing services are as follows:
◆ Scaling calculation: InforSuite service can realize faster response when the load is heavy, automatically adding new nodes.
◆ Disaster Recovery Mechanism: Provides disaster recovery mechanism for InforSuite services. When enabled, disaster recovery backup can be implemented without any additional configuration by users.
◆ Example exclusive: to provide examples of exclusive mechanism. In this way, different quality of service can be provided to different users. For example, key users can enjoy a single set of InforSuite service resources to ensure the smooth running of key businesses.
◆ Centralized supervision: Provides centralized monitoring capability for multiple resources (hardware resources and virtual resources). Users can manage multiple hosts and virtual machines through an interface.
◆ ISV / SI: Provides virtual machine-based application deployment solutions to help developers implement virtual machine-based application deployment and reduce the error probability of on-site deployment, facilitating maintenance.

4.InforSuite cloud management console

The InforSuite Cloud Management Console provides management of the cloud platform and management of all parts of the cloud platform. It is divided into two main parts: Cloud Resource Management: It mainly implements the management functions of physical computing units and virtual computing units. Achieve the most basic management of cloud resources. Deliverable service management: Management of InforSuite services, aggregation of InforSuite services, allocation of resources used by InforSuite services, templates of InforSuite services, etc.
