# Workload architecture
<a name="telcorel02"></a>

 The workload architecture section focuses on the design patterns and architectural approaches required to build highly available, fault-tolerant, and scalable telecom networks in the cloud. This includes best practices for distributed user plane deployments, control plane redundancy, flexible network function scaling, and cloud-native load balancing solutions.

 Telecom networks underpin essential communication services that individuals and businesses rely on daily. Maintaining the resilience and fault tolerance of these cloud-based networks is paramount as disruptions can hinder vital connections and access to emergency services. Robust network architectures with redundant components, failover mechanisms, and self-healing capabilities are crucial to providing the availability required for modern telecommunication needs.
