East-West Traffic Control refers to the management and security of network traffic that flows between servers, applications, or services within a data center or cloud environment, as opposed to North-South traffic (which flows between external clients and the data center). This type of traffic is critical in modern architectures like microservices, where internal components communicate frequently.  

**Explanation:**  
- **Purpose:** Prevents lateral movement of threats, enforces policies, and optimizes performance between internal systems.  
- **Key Features:** Segmentation, monitoring, and policy enforcement (e.g., firewalls, zero-trust models).  

**Example:**  
In a Kubernetes cluster, containers (pods) often communicate internally. East-West Traffic Control ensures that only authorized pods can interact, using tools like network policies or service meshes (e.g., Istio).  

**Tencent Cloud Solution:**  
Tencent Cloud offers **Virtual Private Cloud (VPC)** with advanced network policies and **Security Group** rules to manage East-West traffic. For microservices, **Tencent Cloud TSE (Tencent Service Engine)** provides service governance, including traffic control and observability.
