云计算概念和根源

Cloud Computing Concept and Roots

Bola Abimbola

摘要:

云计算是分布式计算的特定实现。它继承了分布式计算的许多特性,如可扩展性、可靠性和分布透明性。透明中间层将底层平台从最终用户那里抽象出来。虚拟化技术是云计算的基础。虚拟机提供物理服务器资源的抽象,并安全地隔离多租户环境中的不同用户。对于云服务消费者来说,所有的计算能力和资源都是通过客户端平台的高速互联网访问来访问的。这消除了构建和维护本地数据中心的成本。资源池化和快速弹性是云计算的主要特征。云计算的可扩展性来自于可以跨越多个数据中心和地理区域的资源。实际上,云计算的可用资源量没有限制。新的处理和存储资源可以无缝地添加到云资源池中。

英文摘要:

Cloud computing is a particular implementation of distributed computing. It inherited many properties of distributed computing such as scalability, reliability and distribution transparency. The transparency middle layer abstracts the underlying platform away from the end user. Virtualization technology is the foundation of Cloud computing. Virtual machine provides abstraction of the physical server resources and securely isolates different users in multi-tenant environment. To the Cloud services consumer, all the computing power and resources are accessed through high speed internet access by client platforms. This eliminates the cost to build and maintain local data center. Resource pooling and rapid elasticity are the main characters of Cloud computing. The scalability of Cloud computing comes from resources which can span multiple data centers and geographic regions. There is virtually no limitation on the amount of resources available from Cloud. New processing and storage resources can be added into the Cloud resource pool seamlessly.
