云主机 Live Migration 技术，SpeedyCloud 自主研发的云主机Live Migration技术，采用多种迁移策略相结合的方式，将云主机迁移的downtime控制在10毫秒以内，目前该水平达到国内领先。迁移过程保证虚拟机的服务可用性，对用户完全透明无感知。

迁移的数据包含三类：磁盘、内存，设备状态（CPU 寄存器状态），数据的迁移基于 TCP 协议，通过网络来传输完成，包括准备阶段、全量数据迁移阶段、变更数据迁移阶段。在迁移过程中SpeedyCloud采用 pre-copy 策略，通过不断的快速循环来完成数据的拷贝，在时机合适时，即单次循环拷贝数据大于变更数据时，进行网络环境切换，并瞬间同步设备状态，之后停止源服务器，启用目标服务器，完成整体的迁移过程。

Cloud server Live Migration technology: The Live Migration technology is fully developed by SpeedyCloud, using the combination of multiple migration policies and is able to control the migration downtime within 10 millisecond. So far, this technology has reached the advanced level in China. During the migration process, the service of the virtual machine is still available and is completely transparent to the users.

The migrated data contains three categories: disk, memory, and device status(the register status of CPU ). Data migration is based on the TCP protocol and finishing data transmission via network. The whole process includes three phases which are preparation phase, full data migration phase, change data migration phase. SpeedyCloud uses pre-copy strategy and complete copies of the data through continuous rapid cycling. While the single loop of copying data is greater than the change of the data, the network environment will be switched and  the state of the device will be instantaneously synchronized. After that, the source server will be stopped which enables the target server, and the the overall migration process is completed successfully after that.

跨数据中心的 Service-Bus 任务调度技术，为云计算平台的跨地域资源调度提供了通信保障，让云计算平台上通信可用性达到99.9999%，相当于在一年中仅有30秒时间不可用，该技术为 SpeedyCloud 云平台专用，在同类产品中居于国内领先地位。工作过程中，发送端通过多通道技术同时将任务发送到多个消息队列中，之后消费端会按照一定的策略选择与自己连接最稳定的消息队列进行通讯，并执行相关任务，以保证消息的最大可用性。

The Service-Bus task scheduling technology across the data center provides communication guarantee for the inter-regional resource scheduling of the cloud computing platform. The communication availability of the cloud computing platform is 99.9999%, which is equivalent to only 30 seconds unavailable in one year. The technology is specifically for SpeedyCloud cloud platform, taking a leading position in similar products. During the process, the sender sends the task to multiple message queues through multi-channel technology, and then the consumer will selec the most stable message queue to communicate with each other according to certain policies and perform related tasks to ensure message Maximum availability.

精细化的 Qos 控制技术，SpeedyCloud 的精细化 Qos 控制技术可以对各类云计算资源的服务质量进行全方位的控制，以此来提升用户使用云计算服务的总体满意程度。针对某些用户的关键性核心业务，这类服务通常需要十分严格的性能保证（如银行核心业务等），需要100%确保其相应的QoS需求；而另外一些用户则并不需要十分严格的 QoS 保证（如中小型的企业级应用）。因此，针对不同类型的 QoS 需求，SpeedyCloud 可以在计算、存储、网络等多个维度上进行精细化的管理，可实现动态调整，实时生效，该技术在国内市场中处于领先水平。
