云计算相对于传统的计算,使用模式发生了革命性的变化,云计算的架构更加复杂,涉及到的技术面很广,本论文从下面几点进行介绍。第一层物理计算服务器,存储服务器,交换、路由器、防火墙等网络设备。第二层虚拟资源层,包括对整个第一层的资源逻辑抽象化,物理服务器被虚拟化后可以在其上运行更多的虚拟主机,底层多台物理存储服务器虚拟化为一个大的逻辑存储空间。统一虚拟化为三种类型资源,虚拟计算资源,虚拟存储资源,虚拟网络。第三层虚拟资源服务层,这层主要是提供具体的服务功能,例如网络的负载均衡,虚拟化私有网络,虚拟化路由,虚拟机化安全组,虚拟化防火墙,虚拟机服务,虚拟机疏散,热迁移,冷迁移等一系列的资源服务。最后是系统的监控服务:全私有云的监控服务,认证服务,日志管理,访问授权,安全审计等核心管理功能。
Compared with traditional computing, cloud computing has undergone revolutionary changes in its usage model. The architecture of cloud computing is more complex and involves a wide range of technologies. This paper introduces the following points. The first layer of physical computing servers, storage servers, switches, routers, firewalls and other network equipment. The second layer of virtual resource layer, including the logic of the entire first layer of abstraction, physical servers can be virtualized to run more virtual hosts on the ground more than one physical storage server virtualized into a large logical storage space. Unified virtualization into three types of resources, virtual computing resources, virtual storage resources, virtual networks. The third layer of virtual resource services layer, this layer is mainly to provide specific service functions, such as network load balancing, virtual private network, virtualized routing, virtualization security group, virtualization firewall, virtual machine services, virtual machine evacuation , Heat transfer, cold migration and a series of resource services. Finally, the system monitoring services: private cloud monitoring services, certification services, log management, access authorization, security auditing and other core management functions.
