云计算涉及的术语和一些概念 整理ing
1、Amazon Web Services - Amazon的云计算服务
2、Simple Storage Service - S3简单的存储服务
3、Elastic Compute Cloud - EC2，弹性可扩展的云计算服务器
4、Simple Queuing Service - 一种简单的消息队列
5、SimpleDB - 简单的数据库管理
6、SAAS - Software-as-a-service 软件即服务
7、OSGI技术 - 提供一种面向服务架构，能使这些组件动态地发现对方
8、JINI - Java Inteligent Network Infrastrute
9、JavaSpace - 是建立在JINI基础上的一个服务，JavaSpaces提供了一种完成共享分布式计算的机制
10、Distributed Computing - 分布式计算
11、Parallel Computing - 并行处理
12、Grid Computing - 网格计算
13、MSP - 管理提供服务商
14、HAAS - 硬件即服务
15、SLA - Service Level Agreement 服务等级协议
16、Service Grid - 服务网格
17、GSM - Grid Service Manager 网格化服务管理器
18、GSC - Grid Service Container 网格化服务容器
19、PU - Processing Unit - 处理单元
20、Data Grid instance - an independent data storage unit, also called a cache. The Data Grid is comprised of all the Data Grid instances running on the network.
?21、Space - a distributed, shared, memory-based repository for objects. A space runs in a space container - this is usually transparent to the developer. In GigaSpaces each Data Grid instance is implemented as a space, and the Data Grid is implemented as a cluster of spaces organized in one of several predefined topologies.
?22、Grid Service Container - a generic container that can run one or more space instances (together with their space containers) and other services. This container is launched on each machine that participates in the Data Grid, and hosts the Data Grid instances.
?23、Replication - a relationship in which data is copied between two or more Data Grid instances, with the aim of having the same data in some or all of them.
?24、Partitioning - new data or operations on data are routed to one of several Data Grid instances (partitions). Each Data Grid instance holds a subset of the data, with no overlap. Partitioning is done according to an index field in the data - operations are routed to partitions based on the value of this field.
25、In-Memory Data Grid（IMDG） - 内存数据网格
26、SBA - Space-based Archittecture
