What is SaaS Cloud Migration?
SaaS 云迁移是将您的软件应用程序从本地基础设施迁移到基于云的软件即服务 (SaaS) 平台的过程。
This means instead of hosting and managing your software yourself, a third-party provider handles everything, delivering the software to you over the internet.
Why Migrate to SaaS?
Businesses migrate to 软件即服务 (SaaS) for varying reasons. Normally, companies do it when they want to adjust their resources and assign other tasks to their IT teams. Here are some of the main factors that influence a migration to SaaS:
- 成本: Businesses may look to cloud migration for cost purposes; on-premises are typically more expensive.
可扩展性: Cloud services move resources based on real-time demands. - 可访问性: 当员工不在办公室工作时,公司通常会迁移到SaaS云。本地基础设施只能在现场使用,而云是远程的。
- 更新: 考虑迁移到 云服务 如果您和您的IT团队需要自动更新。
- 协作: 如果您的团队成员分布在多个地点,请考虑云迁移。

典型的云迁移过程如下:
- 直接迁移(Lift and Shift): 也称为重新托管。在此过程中,您将应用程序从本地迁移到云端,但不会进行太多更改。
- 重构: 也称为平台重构。在此阶段,您会根据云设置对应用程序进行细微调整。
- Rebuild/Re-architecturing: 在此阶段,您为云重新设计应用程序。
- Replacing/Repurchasing: 在此阶段,您将完全切换到基于云的 SaaS 应用程序。
