From Java Microservices to Lambda functions – a journey

You may be one of many organisations (or an engineer in one) that operates Java microservices in the cloud with a desire to move towards a serverless architecture, but are unable to justify the steep migration path (e.g. decomposing your services into functions, rewriting in a more suitable language etc.) from those microservices to the likes of AWS Lambda. But fear not! Because with the help of spring-cloud-function you can repurpose your existing microservices into serverless functions in a gradual and controlled manner, with minimal effort or interruption of service. In this article I’ll explain how you can achieve this...

Performance Tuning Next.js

TL;DR: Next.js 9.3 introduces getStaticPaths, which allows you to generate a data-driven list of pages to render at build time, potentially allowing you to bypass server-side rendering for some use cases.

Alexa has an SDK that allows you to develop Skills in a number of languages including Java and Javascript, but also C#, Python, Go and probably...

Booking a Meeting Room with Alexa – Part One

Hey there! This is part one into my adventures of developing an Alexa skill. I was inspired recently on client site, where I saw they’d installed a shiny new room booking system. Each meeting room had a touch screen setup outside of it, and from it you could see who’d booked the room, and also use it to book the room out if it was available. It had the right idea, but from talking to people I learnt that it wasn’t the most user-friendly, and that it had cost a pretty penny too! I’d been looking for an excuse to...
