Cloud Dedicated Cluster (CDC)
Cloud Dedicated Cluster (CDC) is a managed infrastructure product by Tencent Cloud designed to extend public-cloud capabilities into customers’ on-premises data centres (IDCs). It is delivered as integrated rack cabinets deployed in the customer’s facility, with connectivity to a nearby public cloud region for unified management via console, API, and SDK. CDC combines the benefits of public-cloud services (flexibility, scaling, tooling) with the advantages of local deployment (low latency, data locality, compliance). The solution targets enterprises that require high-performance near-field services or strict data governance in regulated or industrial environments.
Key Features
-
Minimal deployment starts with only 8 servers to provide a complete local service environment, helping reduce idle-resource cost.
-
Local data retention in customer-specified IDC ensures compliance and supports physical device de-magnetisation when hardware leaves the site.
-
Unified hybrid-cloud experience: manage CDC resources via the same console, APIs, and SDKs used for Tencent Cloud’s public-cloud region.
-
High reliability and reduced operations effort: Tencent Cloud provides remote unified operations and monitoring, aiming to ease edge-/datacentre ops burden.
-
Tailored for hybrid, edge, and regulated deployments: Suitable for smart industry, healthcare, transportation, and finance, where low latency and local data are critical.
Use Cases
-
Manufacturing automation and industrial IoT where real-time control and low latency at the local facility.
-
Healthcare and medical institutions need to keep sensitive data on-site but leverage cloud-native tooling for analytics and applications.
-
Media and entertainment operations with near-field rendering, graphics or video workflows that benefit from local compute plus cloud linkage.
-
Financial services, telecommunications, or other regulated industries requiring physical isolation, compliance, and dedicated infrastructure.
Pricing & Plans
Publicly available detailed pricing for CDC is not standardised in the same way as public cloud services. The product materials note a subscription model (e.g., “first-pay + monthly pay”) and deployment costs that depend on client site, rack configuration, and scale.
You will need to contact Tencent Cloud sales for a tailored quote based on your IDC location, required capacity, contract term, service level, and resource profile.
Integrations & Compatibility
-
Seamless integration with Tencent Cloud services for unified hybrid cloud operations—CDC resources are managed via Tencent Cloud’s console and toolchain, just like public-cloud resources.
-
Supports IDC deployments with third-party cabinets and the reuse of existing hardware infrastructure under certain conditions.
-
Can be used in combination with other distributed cloud offerings from Tencent (e.g., edge zones, dedicated zones) to build large-scale hybrid or multi-site architectures.
Pros & Cons
| Pros | Cons |
|---|---|
| Enables cloud-native services with local IDC deployment, supporting low latency and data locality | Requires on-premises facility readiness (e.g., IDC space, power, cooling, cabling) |
| Unified toolchain with Tencent Cloud public cloud for hybrid operations | Pricing and contract complexity may be higher than standard public-cloud services due to customisation |
| Strong suitability for regulated or industry-specific use cases needing dedicated infrastructure | Global region support and ecosystem maturity may vary compared to major global public-cloud offerings |
| Allows reuse of on-premises or IDC infrastructure and local compute racks | For smaller/simple workloads, the overhead of deployment may not justify the cost vs the standard public cloud |
Final Verdict
Tencent Cloud Dedicated Cluster (CDC) is a solid solution for enterprises that need the agility and tooling of public-cloud platforms but must operate in on-premises environments or meet strict data-locality and latency requirements. If your organisation operates in industries such as manufacturing, healthcare, telecommunications, or finance, and you have the infrastructure and commitment to deploy on-site racks, CDC offers a hybrid path with managed operations and cloud native features.
For simpler applications, smaller teams, or purely public-cloud strategy, a standard public-cloud infrastructure may be more cost-effective and faster to deploy.
