Maximizing Scalability with Go and Redis: A Telemetry Processing Journey

At Delivery Hero, we process a staggering 10,000 requests per second globally, particularly in our critical TIER1 flow, where we handle telemetry data primarily from riders' phones. In this session, we'll delve into how we harnessed the power of Go and Redis to handle this high-load, mission-critical system at an incredibly low cost. Key Points: Go and Redis as the Perfect Pair: Discover how Go and Redis form the backbone of our telemetry processing infrastructure. Go's concurrency model and performance complement Redis's high availability and resilience, enabling seamless handling of our demanding operations. Efficient Data Management with Redis: Explore how Redis's versatile features, including sorted lists and key expiration (TTL), enable efficient telemetry data storage, event queue management, and fraud prevention. Learn how Go's native support for Redis interactions streamlines integration and enhances overall system performance. Scalability Made Simple: Dive into how Go and Redis effortlessly scale to handle our high-volume telemetry flow. With Go's lightweight footprint and Redis's scalability features, such as automatic sharding and replication, we ensure our system remains responsive and reliable, even under peak loads. Cost-Effectiveness and Resource Optimization: Learn how we achieved cost-effectiveness by leveraging the smallest Redis instances available, strategically deployed across multiple regions. Explore how Go's efficient resource utilization and Redis's pay-as-you-go pricing model contribute to significant cost savings without compromising performance. Customized Data Flows and Experimentation: Our implementation with Redis has opened doors for various experiments, including different location frequency updates, giving us the flexibility to optimise and innovate based on unique service needs.testing different telemetry processing strategies, empowering continuous optimization and innovation.

Flutter for frontenders or There and Back Again

Today, there is a vast number of technologies that enable the development of cross-platform applications. These technologies are evolving rapidly, attracting large communities, and more frequently, companies are adopting them. For example, Flutter is a powerful framework that allows developers to create cross-platform applications. With a high probability, every developer may encounter the need to use such development tools, and it’s great that frameworks like Flutter come with detailed documentation and extensive community support, making it relatively easy to start developing with them. Although, at first glance, everything might not seem smooth, and the desire to revert to familiar methods may arise.

Native GUIs For All

The Fyne app development framework supports virtually all platforms (Windows, macOS, Linux, FreeBSD, Android, iOS and the web). But it can be used only with the Go programming language. We will look at a small project that builds on top of Fyne and opens it up to any programming language. The GUI itself doesn't have to be programmed at all but is only described in a specialized but flexible UI description language that is easier to read and more concise than HTML. The visual appearance can be influenced with a theme configuration. Communication between the GUI part and the application logic can be done with standard I/O. So even bash scripts can be used for GUI applications. Examples will be in Python and bash. This is especially interesting for DevOps people or anybody who automates stuff to 99% but needs some consent or information from a human from time to time.

Passkeys on Android: How to get rid of passwords

Passwords. Or two factors? What about multiple factors? Which email did you register with? Why is 'password123' not working on this side, that is password is shared everywhere else? If you recognize some of those questions, I am happy to add another couple: What are passkeys? Or how about: How to use passkeys to replace passwords in an Android app? In this workshop I will walk through the later two questions: How to build an Android App that registers and signs users in, using passkeys. Expect a quick explanation of this fancy new technology, why it will replace passwords and how you can store them either on your mobile devices or on dedicated hardware. Following that, a fictive application and service will be built to show you how to use those passkeys and which moving pieces you will need. Expect to use you Android Studio with Kotlin and common best practices to build an Android app, talking to the public available backend.

Learn Flask the hard way: Introduce Architecture Patterns

Flask is a popular and flexible web framework for Python, but building scalable and maintainable Flask applications can be challenging without a solid understanding of architecture patterns. This workshop aims to provide participants with a detailed explanation of applying architecture patterns to Flask projects. By exploring various design principles and best practices, attendees will learn how to structure their Flask applications for improved scalability, modularity, and maintainability. Focusing on the Repository, Unit of Work, and Use Cases patterns, attendees will gain experience in applying these patterns to enhance code organization, maintainability, and testability. All these layers are wired together using Dependency Injection, which is yet another powerful tool to use in your applications. The application we are going to build is stored in: https://github.com/ShahriyarR/hexagonal-flask-blog-tutorial We are going to completely rewrite the official Blog application described in Flask documentation by applying architecture patterns. All abstraction layers are covered by unit and integration tests, which will give the attendees a detailed view of why it is important to structure the application using architecture patterns.
