What if you could run 35 AWS services locally in under 25 milliseconds, using just 13 megabytes of memory, with a single Docker command and no cloud bill? That's exactly what Floci does.In this episode, Frank Delporte talks with Hector Ventura, the creator of Floci, a free and open-source cloud emulator built with Quarkus and GraalVM native compilation. Hector walks us through why he built it when LocalStack dropped its open-source community edition, how AI tooling helped him accelerate development of new service integrations, the challenges of keeping GraalVM happy with third-party libraries, and the road ahead for Azure and GCP support.If you're a developer who wants fast local testing, a DevOps engineer writing Terraform, or a student learning cloud without the cost, Floci is worth a look!Guest: Hector Ventura Foojay Author page LinkedInLinks On Foojay: Introducing Floci: A High-Performance, GraalVM-Powered AWS Emulator Floci project site Floci on GitHub Migrate from LocalStackContent00:00 Introduction of topic and guest01:48 What is Floci?02:15 How Floci compares to LocalStack03:01 Why Hector started Floci04:02 Floci emulates the cloud APIs05:02 How additional services got integrated with AI assistance06:31 Meaning of the name Floci07:07 Why Quarkus and GraalVM as the starting point for Floci09:35 How Floci starts up very fast and only uses a low amount of memory12:18 GraalVM can be hard with some libraries or frameworks14:02 What is needed to use Floci14:56 The challenges to support AWS, Azure, GCP and finding contributors20:24 Funding Floci21:04 How data is persisted in Floci22:37 Verifying Floci versus the "real" APIs with compatibility tests23:56 In the future: UI for Floci25:04 Biggest challenges while creating Floci25:32 Functionality compared between Floci and LocalStack and migrating28:15 Feedback from the Floci users28:58 Long-term plans for Floci29:59 Biggest surprises during the development of Floci31:00 Best use-cases for Floci32:12 In the next releases...33:31 How to get started with Floci35:00 Conclusion
