What happened

Uber, much like the cities it serves, is constantly growing and changing, which means its network traffic must be carefully managed to avoid congestion. The company has evolved its technical strategies over time to keep application traffic flowing smoothly across its platform.

A key part of that effort is application awareness on Cloud Interconnect, an industry-first tool for prioritizing application traffic across hybrid networks. Uber helped design the tool as an early partner, and it uses DSCP marking and configured queuing profiles to classify and prioritize critical end-user traffic over less time-sensitive data.

The tool offers four major features: traffic handling, congestion response, latency management, and cost efficiency. Traffic is sorted into six distinct classes, and business-critical data is protected through strict priority or bandwidth sharing policies. Uber began deploying it during a private preview, starting with Google Cloud Interconnect locations in Phoenix, Arizona, and Ashburn, Virginia.

Why it matters

For global-scale organizations like Uber, migrating distributed and hybrid applications is risky if it interrupts service. Application awareness lets Uber move massive amounts of data, including large analytics workloads and emerging AI use cases, without congesting the network or degrading business-critical application performance.

Legacy overprovisioning approaches treat all traffic equally and can drop high-priority data during bursts, making them costly and unreliable at Uber's scale. Application awareness offers predictable low latency and protects critical traffic, giving Uber the confidence to proceed with a Google Cloud migration while reducing the risk of service interruptions.

Key facts

Uber acted as an early design partner for application awareness on Cloud Interconnect.

The tool classifies traffic into six distinct traffic classes and uses DSCP marking and configured queuing profiles.

Uber deployed the feature starting with Google Cloud Interconnect in Phoenix, Arizona, and Ashburn, Virginia.

Application awareness helped Uber prioritize critical traffic and reduce reliability risks during network congestion events.

What to watch next

Other organizations facing similar hybrid and multicloud migration challenges may adopt application awareness on Cloud Interconnect to protect critical traffic without expensive overprovisioning.

As AI workloads grow and data transfer demands increase, tools that intelligently manage network congestion could become essential for maintaining service reliability.
