Sdn Thunder, NFV smoke again. As one of the most active emerging network technologies, NFV has become a new weapon for advancing the pace of network evolution and coping with the business challenges of the cloud computing era. Multi-industry applications, NFV trend compared to SDN,NFV focus on the network of four to seven layers of functions and applications, covering the traditional routers, firewalls, load balancing, IPS, application gateways, including VPN, NAT Gateway, security services, application identification, analysis, control and so on. In the current application environment, NFV is the application object that operators mainly focus on. NFV ...

"IT168 book" This article extracts from the Zhou Hongpo "cloud computing Security and privacy". In the previous section, we established the requirements and benefits of the IAM principles and practices for applying standards to cloud computing services. In this section, we will discuss the criteria for IAM, which is the catalyst for the enterprise to adopt cloud computing services. 　　Organizations that are currently evaluating cloud computing services based on business and operational guidelines should take into account the commitment of cloud computing service providers and support for identity and access management standards. 5.7.1 mechanism of the IAM standards and norms below the ia ...

is direct-attached storage obsolete? Direct-attached storage is what we often call Das (direct-attached storage), usually the storage media that is installed inside the server or installed in an expansion enclosure directly connected to the server. There must be a fixed binding connection between the DAS storage and the server, so there is no network structure between them, but direct data read and write. Das has been considered a inefficient structure in the way servers and storage are connected, and it is not convenient for data protection. Direct-attached storage cannot be shared, so often out of ...

In 09, IBM announced the latest storage strategy for cloud computing, an application called "Enterprise Intelligent Cloud storage", a private cloud based storage and archiving technology designed to provide application support to enterprise customers. This cloud storage is implemented primarily through storage virtualization. This is in contrast to the existing Low-cost cloud storage application environment offered to customers by EMC and other vendors, with a distinction between two or three-level data replicas or storage applications in development and testing environments. IBM's cloud storage is based on IBM storage virtualization with a variety of storage devices to achieve ...
