Confluent, a leader in data streaming and real-time analytics, provides a cloud-native platform that powers mission-critical applications for thousands of businesses. Operating Confluent Cloud across AWS, Azure, and Google Cloud brings immense flexibility — but also introduces networking complexity and security challenges. Each cloud provider has its own networking model. Making things work consistently across AWS, Azure, and GCP was a huge challenge. - Alvaro Aleman, Staff Software Engineer at Confluent To address their challenges Confluent partnered with Isovalent — a cloud-agnostic networking and security platform, built for Kubernetes at scale. Here’s how Confluent leveraged Isovalent to simplify operations, optimize data flow, and ensure high-performance networking across cloud providers. 📽️ Watch our conversation with Confluent’s experts to hear firsthand how they tackled multi-cloud networking challenges with Isovalent Networking for Kubernetes.

Navigating multi-cloud networking challenges Operating across multiple cloud providers introduces distinct challenges, requiring a consistent, scalable, and cost-effective approach to networking: Inconsistent Networking Features Across Clouds: Each cloud provider has its own networking model, making it difficult to maintain uniform performance, security policies, and visibility across AWS, Azure, and GCP. Developer Complexity & Efficiency: Different CNI (Container Networking Interface) implementations across cloud providers forced teams to manage multiple configurations, slowing deployments and troubleshooting. Security & Compliance Gaps: Enforcing consistent security policies and implementing Zero Trust networking across diverse cloud environments remained a challenge.. Limited Network Observability: Debugging networking issues was time-consuming and inconsistent due to lack of deep visibility across cloud providers. Cloud providers charge for data transfer between availability zones and regions, so optimizing traffic routing is critical. Alongside using Cilium, we can ensure that customer traffic stays within the same availability zone, avoiding unnecessary fees and reducing cloud costs. - Alvaro Aleman, Staff Software Engineer at Confluent Transforming multi-cloud networking with Isovalent Confluent selected Isovalent Networking for Kubernetes as its foundation for cloud-agnostic, cost-optimized networking that enables unlocking efficiency, security, and operational simplicity.
