摘要
云计算代表一种全新的计算模型,并从根本上改变IT服务的方方面面。云环境的主要优势在于降低数据中心的成本支出,并在需要资源时获得动态接入,而不需耗费人力、时间,不影响工作人员的效率和组织竞争力。但云计算仍然存在一些网络性能和安全的问题。所有运营云的企业、政府机构和服务提供商,还有支持云基础设施的设备提供商必须在其设计中考虑这些因素。可用云性能和安全测试工具检测云应有的性能,以实现其结果。
Cloud computing is a completely new computing model that is fimdamentally changing various aspects of IT services. The key advantage of cloud computing lies in its capability to reduce data center CAPEX, the ability to allow dynamic accesses on demand, and no cost of manpower, time, efficiency of the staff and competitiveness of organizations. However, there are still some issues in network performance and security to be addressed in cloud computing. All enterprise, government agencies and service providers running clouds, as well as equipment providers supporting cloud infrastructures, must consider these factors in their designs. Cloud performance and security testing tools can be used to test the perfornmnce a cloud is supposed to have to achieve this goal.
