We’ll cover the architecture and the object ive criteria used to determine Spot eligibility\, along with the automated system we built to manage it\, powered by Lambda functions\, periodic eva luators\, service-level checks\, and a central orchestrator that could saf ely toggle Spot for each workload.\n\nYou’ll see how we balanced substan tial cost savings with strict reliability requirements in a high-traffic e cosystem. From handling Spot interruptions and fluctuating AWS capacity to validating graceful shutdown paths\, LB deregistration behavior\, and com puting a custom “Spot Placement Score\,” this session demonstrates how to adopt Spot at scale using automation\, guardrails\, and data-driven ro llout logic.\n\n**Takeaways**\n- A scalable framework for Spot adoption: Y ou’ll learn criteria\, automation patterns\, and scoring mechanisms that enable safely onboarding thousands of ECS services onto Spot with no manu al effort.\n\n- How to maintain reliability at scale: Gain insight into th e guardrails\, health checks\, and architectural patterns required to make Spot work in large\, business-critical production environments where even a small increase in failure rate is unacceptable.\n\n**Audience**\n- Clou d / DevOps engineers managing large EC2 fleets who want to adopt Spot conf idently at scale.\n- SRE and platform engineering teams responsible for hi gh-availability compute platforms.\n- Engineering managers and architects evaluating cost-optimization strategies for large distributed systems.\n- Organizations spending heavily on AWS compute and looking for scalable\, l ow-risk approaches to reduce costs across a broad service ecosystem.\n\n** Speaker Bio**\nAakash\, is a Senior Platform Engineer at Deliveroo. Being part of the Network\, Edge and Compute(NEC) team\, He's responsible for bu ilding a scalable\, reliable\, cost-effective and engineer friendly platf orm.\n\nLink to elevator pitch: https://drive.google.com/file/d/1l4NPdCQwh 5TbKtRFQd4dHVl4raOnMIkV/view?usp=sharing LAST-MODIFIED:20260105T083034Z LOCATION:Quintype\, Bangalore ORGANIZER;CN=Rootconf:MAILTO:no-reply@hasgeek.com URL:https://hasgeek.com/rootconf/platform-engineering-meet-up-jan-8/schedu le/cost-optimisation-in-ecs-integrating-spot-instances-at-scale-2GKRMbji8J HGMm6vcrTD3c BEGIN:VALARM ACTION:display DESCRIPTION:Cost optimization in ECS: integrating spot instances at scale in 5 minutes TRIGGER:-PT5M END:VALARM END:VEVENT BEGIN:VEVENT SUMMARY:Transition DTSTART:20260108T114500Z DTEND:20260108T115500Z DTSTAMP:20260421T132321Z UID:session/QXGS2mgcjKDJCRTa8Svb8k@hasgeek.com SEQUENCE:2 CREATED:20260105T081041Z LAST-MODIFIED:20260105T081222Z LOCATION:Quintype\, Bangalore ORGANIZER;CN=Rootconf:MAILTO:no-reply@hasgeek.com BEGIN:VALARM ACTION:display DESCRIPTION:Transition in 5 minutes TRIGGER:-PT5M END:VALARM END:VEVENT BEGIN:VEVENT SUMMARY:Scale-to-zero made native with KubeElasti DTSTART:20260108T115500Z DTEND:20260108T121500Z DTSTAMP:20260421T132321Z UID:session/Pz9ELQQMxPYB6kP1KuP5FY@hasgeek.com SEQUENCE:4 CATEGORIES:Talk (30 mins) CREATED:20260105T081051Z DESCRIPTION:# Description\nModern Kubernetes platforms waste up to 80% of resources on idle services\, and most scale-to-zero tools force code chang es or risk reliability by being in the hot path. \n\nThis session demonstr ates KubeElasti's first-principles approach to scale-to-zero\, interceptin g and queueing requests only when needed — never introducing latency dur ing normal operation. Unlike solutions that demand architectural refactori ng\, KubeElasti integrates natively with Kubernetes — no code changes re quired.\n\nKnow More at: [KubeElasti Website](https://kubeelasti.dev)\n\n# Benefits to attendees\n\nAttendees will see live demo\, learn how to enab le cost-efficient scaling\, and explore deployment best practices that rou tinely deliver significant infrastructure savings. Perfect for platform en gineers\, SREs\, and architects seeking cost optimization without compromi sing reliability or requiring application refactoring.\n\n# Speakers\n\n## # Shubham Rai\n**Founding Platform Engineer @ [Truefoundry](https://truefo undry.com)**\n\nShubham Rai is a platform engineer working in the cloud na tive space for more than 6 years.

It highlights the massive scale of the deployment infrastructure\, which is organized into various deploy ment groups (e.g.\, devel\, prod-canary\, prod)\, and sets the stage by ou tlining the challenges faced by service owners\, such as managing configur ations across different environments\, controlling which clusters receive specific deployments\, and implementing progressive rollout strategies.\n\ nHalyard is presented as a collection of services and tools for managing t he release and deployment of Helm-based microservices\, allowing users to define targeting rules and control deployment strategies with features lik e error budgets and percentage rollouts. The core of the system is built a round key entities like Service\, Deployment Group (DG)\, Version\, and Cl uster. The presentation also details the `halctl` command-line interface\, which service owners use to query deployment status and perform operation s\, and concludes with a look at future developments\, including moving to ward a Helm-native agent approach\, leveraging Flux Controllers\, and inte grating with internal LLM toolsets for easier investigations.\n\n---\n{Men tion 1-2 takeaways from your session}\n\n * Halyard manages over 1\,000(g rowing continuosly) microservices across approximately 5\,000 Kubernetes(g rowing continuosly) clusters at Confluent.\n * The system allows service owners to control version deployment and progressive rollouts across vario us groups.\n\n---\n{Which audiences is your session going to beneficial fo r?}\n\n * **Software Engineers and Service Owners** interested in solving complex microservice deployment and release management challenges at high scale.\n * **DevOps and Site Reliability Engineers (SREs)** looking for insights into large-scale\, automated\, Kubernetes-based deployment archit ectures and tooling (like Helm and Flux).\n * **Engineering Leaders and A rchitects** exploring strategies for managing versioning\, progressive rol louts\, and configuration across thousands of clusters and services.\n\n-- -\n\n{Add your bio - who you are\; where you work}\n\nI'm Mustajib Mohamme d Khan a senior software developer at confluent.
