How we use Airflow with Composer

At lastminute.com, we use Apache Airflow, managed through Google Cloud Composer, to orchestrate complex workflows. This article explores why we chose Composer as our Airflow distribution, how we use it to schedule a wide range of tasks, and how we organize files and resources to ensure scalability and maintainability. Additionally, we delve into our CI/CD practices, highlighting how we test workflows and manage costs, offering insights for teams seeking efficient and reliable data orchestration at scale in big tech company.

Evolution of a high-performance system: from synchronous to seamless scalability

This article discusses the transformation of a synchronous process in the context of lastminute.com's customer journey for travel planning. The existing system was complex and resource-intensive due to its all-in-one nature, causing scaling and deployment challenges. The article presents the evolved system that separates responsibilities into microservices using message-driven communication.

Event Sourcing - A Light Introduction

Event Sourcing is not one of the most well known pattern in software engineering, but it has a lot of potential uses and areas of application. In this blog post I'd like to explain what is event sourcing, why it matters and why it naturally fits CQRS architectural pattern so nicely, together with an explanation of the various building blocks used.

Impacts of contract tests in our microservice architecture

We learned how to implement contract test for any kind of messages exchanged in a microservices' architecture, now let's see the impacts and why it sped up our development process

An evolving architecture

Over the past few years, constant changes in software development techniques, frameworks and tools led us to rethink how our architecture might evolve over time to sustain changes and support demand from business.
