The development of technology is constantly improving. In the early days of the mainframe, all the calculations were gathered in the mainframe; in the PC era, the main functions of the computer were on one PC; and now, in the era of "cloud computing", there will be new capabilities in computing concentrated. The distributed era of PC, created the bustling Microsoft, Apple; centralized computing constantly creating a "cloud era", but also the achievements of Google. Google is trying to move all the calculator calculations and applications to different "clouds." Microsoft has proposed a new concept of "cloud-end computing" balance: "cloud" and the terminal ...

The key to success or failure of a public cloud service is whether they provide equal or better levels of performance, security, and reliability than the services provided by the enterprise's internal data centers. Gartner predicts that in 2013, the global public cloud market will reach $131 billion trillion, compared with $111 billion last year. 　　To provide the market with the required performance, security, and reliability, cloud service providers are rapidly building virtualized, multiple data center service architectures, or "no walled data centers." Cloud service provider through cloud computing software ...

Recently, the consolidated web, mail, and data security Solutions provider Websense released a security forecast for 2009. It is noteworthy that "cloud security" technology is abused, Web applications and Web 2.0 applications, and other malicious use of the risk will increase dramatically. 　　Hackers make the most of the web-launched attacks, and in 2009 a malicious attack that uses Web API services to gain trust, steal a user's credentials, or confidential information will increase. At the same time, as Web sites that allow users to edit content are becoming more and more popular, the number appears ...

No standard does not equate to SaaS being accepted by the user. We can vitalize some common applications and see what standards SaaS services should have. Today we look at what the standard SaaS CRM should look like in a CRM system commonly used by enterprise users. In fact, many users are not unfamiliar with CRM, as early as 2000, some enterprises have begun to try CRM system. In many people's eyes, CRM is a set of C/s or b/a application system. And when CRM comes into SaaS, he's on the architecture ...

Eight DDoS Attacks Affecting the Security of IoT Enterprises. The overall frequency of Distributed Denial of Service (DDoS) attacks increased in 2016, due in part to the IoT botnet. Neustar said Neustar saw a 40% reduction in DDoS attacks in the January-November period compared to the same period last year. Neustar warned that with the release of botnet code components, dangerous new DDoS deployments will emerge, such as on-going devices ...

In this article, we mainly introduce some related trends of IBM cloud computing and cloud computing industry, including IBM Ensembles, IBM TSAM, IBM WebSphere CloudBurst and so on. 1) IBM Ensembles Ensembles is a set of resource pools implemented through virtualization technology that consists of compute resource pools - Server Ensemble, Network Resource Pools - Network En ...

At present, Web technology has been widely used in intranet and e-commerce, more and more enterprises will be used in web platform, some experts say, this will cause strong security problems. Challenges from the Web in fact, the emergence, development and application of the concept of web security is only three years. But the impetus of the rapid development of web security technology and application has been accumulated for more than more than 10 years. In fact, security in the early years is the "Anti-Virus + Firewall" world, but with the development of technology, especially interne ...

The traditional business intelligence system only serves for the decision person, and is affected by the security factor, the analysis data can only be reflected in the local user terminal, but manifests the way almost is the ordinary computer. With the rapid development of computing and Internet technology, the mobility and activity space of sales, market and decision makers are more and more, more and more managers involved in decision-making, the real-time and interactive requirements of information transmission are more and more high, which puts higher demands on business intelligence. The development of the next generation business intelligence requires that it not only can provide strategic decision for senior decision-makers, but also can ...

First, the differences in the properties of the industry chain led to the decentralized layout of the cloud computing industry Cloud computing industry in the field of economics industry both technology-intensive, capital-intensive and energy-intensive industrial features. If subdivided from the industrial chain: cloud computing industry chain through the cloud infrastructure layer, platform and software layer, run the service layer and the application layer is composed of four parts. The cloud infrastructure layer that is the data center with servers and storage facilities as the main facilities; platform and software layer is mainly cloud platform and cloud software; operation service layer to cloud integration and service-oriented; and application layer to the cloud. .

Recently, the days of the letter with Intel in Beijing jointly hosted the Cloud Data Center Border Protection Solutions Conference. Tian Rong Letter Company Senior vice president, Intel Company senior leadership, as well as more than 40 media reporters attended the meeting. As we all know, cloud data center is the most important link of enterprise informatization Construction, which carries a lot of confidential information of enterprise. After the Prism Gate event, Enterprise's sensitivity to data security has been much more than before, and the protection of Cloud data center has become the most important part of enterprise security construction. To this end, the days of the letter to join Intel released the latest generation of cloud data center boundary protection solution ...

The increasing security risk not only drags down the firewall, it also drags down the antivirus system. "Traditional malware detection methods based on signatures are not enough," said Charles Kolodgy, director of research at IDC's Security product Services Division. The user's behavior is changing, the threat is evolving, but the malware detection technology has not kept pace. "The safety of new ideas security vendors are in urgent need of a new idea to solve this problem, at this time is seen as the future direction of network security cloud security, and it can be a counterweight to the Web security gateway." The generality of both ...

Last year, Premier Wen Jiabao made it clear in the government's work report that "speeding up the development and application of the Internet of things" once again reflects the Government's high emphasis on the developments of Internet of things. With the promotion of national policy, telecom operators are actively involved in the Internet of things, and the internet of Things is an important profit point in the future. 1 IoT architecture and design features of existing EPC middleware the Internet of Things is through radio frequency identification (RFID), infrared sensors, global positioning system, laser scanners and other information sensing equipment, according to the agreed agreement, any items connected to the Internet, exchange of information and communication to achieve intelligent ...

Streaming Media Cloud Service migration method based on OpenFlow Hongshong Wang Zilei Traditional Service migration technology based on application layer middleware or proxy is easy to cause single point failure and poor scalability, and the interaction and long session characteristics of streaming media make it difficult to realize transparent to users. To this end, a streaming media cloud service migration method based on OpenFlow is proposed. Through streaming media cloud migration in the network layer to realize the transparent service to the users, and at the same time, this paper proposes a migration strategy based on user request prediction, and optimizes the service of the system capacity.

Cloud computing multi-tenant is used for almost all software as a service (Software as a Service,saas) application because computing resources are scalable and the allocation of these resources is determined by actual usage. That said, users can access multiple types of SaaS applications over the Internet, from small internet-based widgets to large enterprise software applications. Security requirements are growing, depending on the data on the infrastructure of software vendors that are stored outside the corporate network. Applications requiring multiple tenants are many original ...
