SPU is a monitoring tool designed to enhance security and observability within a Kubernetes cluster. It primarily monitors network traffic to track and analyze interactions between microservices, containers, and other components within the cluster.

One instance is deployed in each worker node of the cluster and an API is expose to interact with the microservices instances to execute packet captures, collect key performance indicators or generate call data records.

Collected data can be streamed to an external source, stored locally or be retreived via API.

An API Gateway (CAPIF) can be used to aggregate multiple kubernetes clusters running SPU instances.

This bring the ability with a single API call to collect information accross all serving kubernetes clusters.

Here’s how it works and why it’s beneficial:

• Aggregation Across Multiple Clusters: With CAPIF acting as a centralized gateway, it allows a single API call to pull information from all the Kubernetes clusters running SPU instances. This eliminates the need for individual services to query or interact with each cluster separately.
• Simplified Troubleshooting: By centralizing access to all the Kubernetes clusters, CAPIF helps resolve the issue of applications needing to be aware of the location of specific subscribers or services. If troubleshooting is needed, CAPIF simplifies the process by providing an interface that can aggregate logs, metrics, and other relevant data from all clusters, regardless of where the issues are occurring.
• Seamless Integration: CAPIF helps decouple the application logic from the infrastructure specifics, meaning applications don’t need to handle the complexity of interacting with multiple clusters. It also reduces the overhead of configuring and maintaining cross-cluster communication for tasks like troubleshooting or data collection.

This setup improves the efficiency and scalability of managing multiple Kubernetes clusters while also enabling a streamlined way of handling inter-cluster communication.
