Cloud computing Security: A look at the advantages of security architecture

Cloud computing has become a viable model for many it needs. In some cases, http://www.aliyun.com/zixun/aggregation/15530.html "> Large enterprises will buy cloud CPU cycles on demand, using Amazon, "Infrastructure as a Service" (IaaS) provided by suppliers such as Rackspace and Terremark for testing, development, and batch processing. In other cases they outsource the entire application, such as handing the email to Google,crm to Salesforce.com, or handing the payroll to ADP.

Although it is indeed valuable, it experts are still keen on a philosophical debate about the value of cloud computing. They want to know whether cloud computing and SaaS, designed for the masses, are truly an option for the Enterprise data center onsite IT equipment. After all, built-in it devices provide wire-speed performance and can be adapted to meet the specific needs of an enterprise.

Recently, chief information security officers convened similar meetings to discuss information security requirements, particularly those related to network security threat management. Security experts have considered a similar question: should large enterprises choose to build their own security gateways or deliver the management of network security threats to cloud services? The conclusions of this paper are:

• Resolve Web threat management issues as quickly as possible, regardless of the solution you choose. While the theoretical thinking on the comparison of internal and cloud services is continuing, the complexity of Web site threat management is growing. As a result, ESG research shows that large enterprises are investing more and more in Web site threat management solutions.

• Enterprise internal and cloud deployment has its advantages and disadvantages. Web site threat Management gateways apply to large, centralized facilities, while SaaS applies to telecommuting and often outgoing employees. Unfortunately, large, globalized enterprises have needs in these areas, so neither security gateways nor SaaS can meet their needs alone. Chief information security officers want to know whether they should choose a solution or implement multiple solutions for multiple vendors.

• Large-scale global enterprises need a tightly integrated hybrid solution. Typically, multinational companies have a large pool of concentrated and dispersed employees. These businesses need consistent policy management, implementation, and oversight, and they have strong security for employees regardless of where they connect from the network. In fact, this is the main reason for implementing a unified hybrid network security solution that combines the flexibility of control and cloud within an enterprise. With a hybrid architecture, large global enterprises can not only centralize management, distribute implementation, but also leverage the "crowdsourcing" advantages of mobile, remote and centralized staff cloud computing communities. This architecture, which combines the best of the two areas, will evolve into a standard enterprise deployment.
