Hello folks,
We’re excited to invite you to our next techBytes meetup @Ocado Technology.

For this edition, we’re piloting a new format. We’ll have one in‑depth topic - Cloud cost optimisation / Technical FinOps on AWS - split into three blocks, each followed by a short break.

During the session, our engineering cloud team - Kasia, Romek, Maciek and Maciek - will share the practical techniques and trade‑offs that have measurably lowered our AWS spend while preserving performance and resiliency at scale.

**\*\*\*Agenda\*\*\***

18:00 - Grab a drink and take a seat

18:05 - Intro

**18:10 - 19:40** (with 2 breaks in between)
**Speakers**: Katarzyna Myrek, Roman Subik, Maciej Mencner, Maciej Józefczyk - Engineering cloud team.
**Topic**: Cutting cloud costs - without cutting yourself on the way

**Abstract:**
Managing cloud costs becomes increasingly challenging as systems grow in scale and complexity.
Based on our experience operating large-scale workloads on AWS, we'll share engineering insights that helped us achieve substantial cost savings across compute, networking, and observability layers - without compromising performance or resilience.
Our goal is to equip you with real, actionable patterns for engineering cloud savings, based on real lessons from scaling infrastructure at Ocado Technology.

——
The session will cover how tools like custom FinOps dashboards, thoughtful architecture decisions, and developer-driven cost awareness can directly influence runtime expenses.
We'll explore trade-offs around services such as CloudFront, NAT Gateway, ECS (both in cloud and at the Edge), API Gateway configurations, and Load Balancers - showing not just what worked, but why.
Additionally, we’ll cover how runtime choices, including EC2 vs. Fargate, instance types, spot instance strategies, and the use of IoT Greengrass for on-premises devices, can drive meaningful savings. Finally, we’ll address observability costs, highlighting lessons learned in managing metrics, logs, and backups efficiently.
