Huawei Cloud UCS Advantages

Huawei Cloud UCS helps you manage cloud native services across clouds and regions while providing a consistent experience. It extends cloud native to wherever your services run, which eases your journey to digital upgrade.

Consistent experience
Distributed Kubernetes clusters running on Huawei public cloud (central region, IEC sites, and CloudPond sites), on-premises infrastructure, and other public clouds can be connected to USC for centralized management. The configuration policies of these clusters can be managed in a unified manner. Tenant permissions are assigned by enterprise project for the refined management of IAM users' permissions on accessing Kubernetes resources. There is a policy center that allows you to configure security policies and resource access restrictions of each cluster for audit compliance.
Collaborative compute scheduling
Huawei Cloud UCS runs on Karmada, a multi-cloud container orchestration project contributed by Huawei Cloud to CNCF. With multi-cloud capabilities, UCS can connect thousands of Kubernetes clusters across clouds and regions and schedule compute by coordinating millions of nodes. Therefore, your applications can scale across clouds and clusters, can be migrated to new clusters when there are application failures, and run in the best condition based on global resource distribution, service characteristics, geographical locations, network QoS, and resource balancing. With UCS, compute is at your fingertips anytime, anywhere.
Intelligent traffic distribution
UCS provides container network orchestration and service discovery for flattened interconnection across clouds and clusters. This enables a consistent service experience and makes for more secure, more reliable communications. UCS distributes requests to the nearest, best-fit cluster to reduce the latency based on different settings such as visitors' CIDR blocks, regions, and carrier networks. It works with service meshes for unified service governance. Scheduling can be implemented based on network QoS. Geographical affinity, automated grayscale release, visualized service topology, and service tracing are also available. These features allow you to manage access traffic globally in real time, on demand.
Data migration with applications
UCS automates cross-cloud data replication for the storage infrastructure, container clusters, and middleware. Data goes wherever your applications run. You can scale your applications on the distributed infrastructure with ease. During scaling, data scanning and rebuild are automated and application-centric. Integrated migration, scaling, and disaster recovery are completed for the entire service.

Huawei Cloud UCS vs Traditional Cloud Native Products

**Table 1** Differences between UCS and traditional cloud native products
Item	Traditional Cloud Native Products	Huawei Cloud UCS
Experience	There are vendor lock-ins due to customizations on cloud native technologies. You may have inconsistent experience when managing clusters in different regions, and you need to spend some time mastering related skills.	Consistent experience Huawei Cloud UCS connects your clusters running on different clouds across central areas, hotspot areas, on-premises data centers, and business locations, providing a consistent cloud native experience.
Scalability	Compute resources cannot be scheduled across clouds.	Collaborative compute scheduling Running on Karmada, Huawei Cloud UCS centrally schedules multi-cloud resources and bursts on-premises applications to public clouds. UCS also provides multiple types of distributed deployment policies, so your applications can run in the best condition based on global resource distribution, service characteristics, geographical locations, network QoS, and resource balancing.
Application management	In most cases, traditional cloud native products manage applications in a single region, demanding little on application migration. When scaling applications across clouds, O&M personnel need to clone and migrate application data manually, which is inefficient and requires heavy workload.	Data migration with applications Huawei Cloud UCS supports synchronous data replication across clouds for you to scale your applications on the distributed infrastructure. Application disaster recovery, scaling, and migration become much easier, improving production efficiency.
Traffic management	Traffic management is decoupled from services. Requests are not distributed on demand. Access latency is high if requests are from a different region or carrier network.	Global traffic management Huawei Cloud UCS distributes requests to the nearest, best-fit cluster to reduce the latency based on different settings such as visitors' CIDR blocks, regions, and carrier networks.
Efficiency	Applications need to be manually deployed in each cluster across clouds, a labor-intensive process.	Ready-to-use services Huawei Cloud UCS allows you to batch deliver service configurations to each cluster in different regions through edge-cloud synergy. Service deployment becomes much faster, and there are no repetitive configurations.
O&M	Services scattered in the central region, in the on-premises data center, and at the edge need to be monitored separately, which results in a heavy O&M burden.	Multi-dimensional monitoring Huawei Cloud UCS supports multi-dimensional monitoring on your resources in all regions and is compatible with open source Prometheus and OpenTelemetry ecosystems.
