2. Cloud – 云基本概念定义
云计算 多用户
定义: 通过互联网提供IT服务的计算模式 定义: 在同一硬件，存储，应用环境下为多个客户
•可以动态调节 及组织提供服务:
•对资源进行虚拟化 • 为不同组织提供虚拟分区
•可以适应低带宽高时延 • 安全复杂程度大大提高
•降低拥有成本 • 对敏感数据的访问控制更加困难
部署模式 供应商
共有云: 通过互联网提供的外部动态资源 Managed Service Providers (MSP):
•提供完整的解决方案
私有云: 在内部网模拟共有云架构以取得云计算的优点， •以服务形式提供
同时又没有安全性方面的问题. Solutions •提供white labels 标识.
Hosting Providers:
混合云: 同时使用云计算架构和传统架构，包括共有云和 •提供Saas, Iaas 或 Paas
私有云 •订阅收费模式

3. 云计算对客户的意义?
• 客户在云计算采用上的现状
– 成本的节省是大多数客户研究和对云计算感兴趣的主要原因
– 但实际的云计算采用并不顺利，主要是技术选择方面的困难和系统转
换的麻烦
– 最终的情况应该是一部分应用完全在云中，而另外的应用将保持传统
的数据中心运行方式.
• 赛门铁克备份解决方案的定位
– 同时为云计算应用和传统应用提供备份恢复解决方案
– 提供更多的功能，并与更多的第三方解决方案集成.

Data Center
Data Center
• 客户将邮件系统迁移到邮件服务提供商如Microsoft, Google 和
Data Center Lotus Live.
• 但客户需要在本地保存邮件归档副本用于检索和法规遵从
• 使客户可以保留对 EV 的投资，使其支持混合应用

27. NetBackup 7 介质服务器重复数据删除MSDP
• NetBackup 7 Media Server 内置的功能
– Simple to configure – wizard based
– Separate deduplication server no longer required
• 专为Vmware优化的重复数据删除
– Enhanced virtual machine “vmdk aware” deduplication*
– NetBackup deduplicates VM data based on what is inside the vmdk
– Globally deduplicate data between virtual systems and physical
• 比较优势
– Competitors have no idea what is inside virtual machine
– They deduplicate vmdk files like any big file – less efficient
– Global deduplication from virtual to physical, virtual to virtual
*Windows only
