Abstract

Cloud networking costs, especially related to NAT gateways, can quickly spiral out of control. In this session, I’ll share how I tackled this issue by implementing a self-hosted NAT gateway at DeepSource, reducing our GCP cloud networking costs by 93%.

We’ll understand the fundamentals of how NAT works and why a self-hosted solution might be the right fit for your infrastructure. We’ll explore the benefits of self-hosted NAT gateways, like cost savings and flexibility, and go through the practical steps for setting one up and managing it.

We’ll also dive into common pitfalls, such as ensuring reliability with proper failover mechanisms, selecting the right kinds of workloads to start with, and addressing security concerns, and how to avoid these challenges for a smooth and secure implementation.

Key Takeaways

• Understand the basics of NAT and its role in cloud networking (primarily GCP).
• Discover how to reduce cloud networking costs, ensure reliability with failover, and address security when implementing a self-hosted NAT gateway

Target Audience

SREs, platform engineers, DevOps teams, and anyone interested in understanding how NAT works and reducing cloud networking costs by self-hosting a NAT gateway.
