Skupper is an open-source Layer 7 service interconnect specifically designed to enable secure and efficient multi-cloud and multi-cluster communication in Kubernetes environments. It simplifies the challenges associated with connecting and managing services across different Kubernetes clusters, enabling seamless communication between applications deployed in diverse locations.

• **Virtual Application Networks (VANs):** Skupper creates virtual application networks that span multiple Kubernetes clusters, abstracting away the complexities of network configurations and enabling direct service-to-service communication.
• **Secure Communication:** Skupper employs mutual TLS (mTLS) encryption to secure all communication within the virtual application network, safeguarding your data and ensuring privacy.
• **No Special Firewall Rules or VPNs:** Skupper eliminates the need for complex firewall rules or virtual private networks (VPNs), simplifying network configuration and reducing operational overhead.
• **Protocol Support:** It supports a wide range of communication protocols, including HTTP/1.1, HTTP/2, gRPC, and TCP, making it suitable for various application types.
• **Multi-Cloud and Hybrid Cloud Connectivity:** Skupper seamlessly connects services across different cloud providers, data centers, and edge locations, enabling multi-cloud and hybrid cloud deployments.
• **Dynamic Routing and Load Balancing:** It employs intelligent routing and load balancing algorithms to optimize traffic distribution and ensure efficient communication between services.

• **Simplified Multi-Cluster Communication:** Skupper abstracts away the complexities of multi-cluster networking, making it easy to connect and manage services across different clusters.
• **Enhanced Security:** Built-in mTLS encryption protects sensitive data and ensures confidentiality in communication between services.
• **Flexibility:** Skupper's support for various protocols and deployment models provides flexibility in designing and deploying distributed applications.
• **Cost and Performance Optimization:** Its intelligent routing and load balancing help optimize traffic flow and reduce costs associated with data transfer and latency.
• **Kubernetes-Native Integration:** Skupper operates natively within Kubernetes, leveraging its APIs and resources for seamless integration.

While Skupper primarily operates through its command-line interface (CLI) and Kubernetes configurations, here's an illustrative example of how to expose a service to the Skupper network:

```bash skupper expose deployment/my-service ```

This command exposes the `my-service` deployment to the Skupper network, making it accessible to other services within the VAN.
