An effective cloud computing system is expected to be powerful, reliable, flexible, and simple to use. The key to building such a system lies in a cloud operating system (OS). Huawei GalaxEngine is a good choice for customers. Huawei GalaxEngine provides powerful virtualization and resource pool management functions, cloud service components and tools, and open application programming interfaces (APIs). Huawei GalaxEngine supports legacy and new enterprise services, improves operating efficiency, and reduces IT costs.

Huawei GalaxEngine Architecture and Its Position in the Cloud System

Huawei GalaxEngine consists of a virtualization infrastructure, a cloud services and cloud management

• Virtualization infrastructure：

The virtualization infrastructure layer virtualizes computing, storage, and network resources and provides virtual resource pools for upper-layer applications. This layer provides virtual computing, virtual storage, virtual network, virtual resource scheduling, and virtual resource management.

• Cloud services:

The cloud service layer is composed of a range of cloud service modules. The cloud service layer schedules and manages lower-layer computing, storage, and network resources through the interfaces provided by the virtualization infrastructure. It also provides cloud services for upper-layer applications through open APIs and interfaces .Services provided by the cloud service layer include (1) basic services such as cloud computing , virtual private cloud , and backup/disaster recovery , and (2) advanced cloud services, such as MapReduce , complex event processing and database capabilities.

Flexible:

• Improves resource utilization by allocating resources on demand and dynamically scheduling resources.
• Supports large-scale deployment and operation.
• The current version supports a maximum of 20 clusters.
• Each cluster supports up to 128 physical servers.
• Huawei GalaxEngine supports more than 10,000 virtual machines (VMs).
• Provides multiple and flexible choices for customers.
• (Optional) Supports multi-tenancy and charging modules to facilitate cloud computing operation.

Secure:

• Uses a unified application management platform to ensure application security.
• Implements centralized data control and rights- and domain-based data management to ensure data security.
• Uses virtualized firewalls to ensure virtualization security.
• Uses a tailored and enhanced Hypervisor to provide optimal performance and high availability (HA).

Efficient:

• Supports quick deployment and improves O&M efficiency to reduce O&M costs.
• Improves IT resource utilization.
• The average utilization improves from less than 10% to more than 70%.
• Improves IT O&M efficiency by 2–10 times because of the usability design of Huawei GalaxEngine.
• Reduces IT operating costs by 30%–70% by highly integrating IT resources.
• Provides centralized management and analysis for massive data, supporting new growth opportunities for enterprises.
• Integration with Huawei hardware to provide optimal performance.
• Provides customized cloud solutions for customers.

Open:

• Provides open APIs.
• Can be integrated with other vendors’ servers, storage and network devices, OSs, and upper-layer application software.
• Supports VMs from multiple vendors.
• Complies with industry standards and de facto standards.
