Transactions move through independent processing units and microservices, with isolation designed to limit disruption when services fail. ### Source excerpt In this article, we will try to understand how the transaction runs through such a cell-based architecture and how the payments are processed even when some services are failing. ## From a single point of failure to a cell-based architecture: How we scaled Mercado Envíos' stock...

The migration was intended to isolate failures, reduce systemic risk, and provide more predictable scalability after the regional database reached its vertical-scaling and operational limits. ### Source excerpt From a single point of failure to a cell-based architecture: How we scaled Mercado Envíos' stock system How we migrated Mercado Libre's second-largest MySQL instance into independent cells using Fury, reducing risk and achieving predictable scalability in Fulfillment. Abstract What happens when the database supporting a continent's logistics reaches its limits? We reached that point when a critical regional database, used for inventory operations across Latin America (LATAM), could no longer scale vertically. This article describes how we transitioned from that consolidated model to a cell-based architecture -- isolating failures, reducing systemic risk, and improving operational predictability -- while keeping logistics running throughout the migration. When a core system reaches its breaking point Software architecture uses patterns to prevent local failures from causing global outages. One of them is the cell-based architecture, which is conceptually similar to the naval bulkhead mechanism. Ships use watertight compartments, or bulkheads, to divide the hull into separate sections. If one compartment floods, the others remain sealed and the ship keeps moving. In distributed systems, we apply the same idea: each cell operates autonomously, with its own compute, database, and traffic. If one cell fails, the rest continue serving requests. This isolation reduces the blast radius and increases resilience. This pattern became essential at Mercado Libre when the stock system powering Mercado Envíos reached its operational limit. Every inbound, outbound, reservation, and logistics movement depended on a single database that could no longer scale. By early 2024, the question was clear: What do you do when vertical scaling is no longer an option? The problem: One database serving all of LATAM Our initial architecture was simple: multiple stock services connected to a single MySQL cluster. This cluster managed: Stock availability per Fulfillment Center Reservations for Fulfil ## Building durable cloud control systems with Temporal DevFeed: [Building durable cloud control systems with Temporal]() Original publisher: [Read original article]() Author: Sergey Bykov Published: 2025-01-16T00:00:00Z Content type: article Language: en Sources: [Temporal Blog]() Topics: [Cloud](), [Architecture & Design](), [Cloud Architecture](), [Multi-tenancy](), [control-plane](), [Scalability](), [Managed Services](), [reliability](), [Resilience]() Tags: [architecture](), [cell-based-architecture](), [cloud](), [cloud-services](), [database](), [high-availability](), [how-to](), [low-latency](), [managed-services](), [multi-tenancy](), [reliability](), [resilience](), [scalability]() ### AI overview Temporal describes how it built Temporal Cloud as a managed service, emphasizing multi-tenancy, durable execution, and a separation between data-plane and control-plane responsibilities. It also explains using cell-based architecture to isolate resources and limit the impact of failures. ### Source excerpt Explore how Temporal leverages durable execution, multi-tenancy, and cell-based architecture to build scalable, reliable cloud control systems.
