Last week, I had the pleasure of presenting Micronaut in action on Google Cloud Platform, via a webinar organized by OCI. Particularly, I focused on the serverless compute options available: Cloud Functions, App Engine, and Cloud Run.

Here are the slides I presented. However, the real meat is in the demos which are not displayed on this deck! So let’s have a closer look at them, until the video is published online.

On Google Cloud Platform, you have three solutions when you want to deploy your code in a serverless fashion (ie. hassle-free infrastructure, automatic scaling, pays-as-you-go): 

Hot on the heels of the announcement of the general availability of JDK 14, I couldn’t resist taking it for a spin. Without messing up my environment — I’ll confess I’m running 11 on my machine, but I’m still not even using everything that came past Java 8! — I decided to test this new edition within the comfy setting of a Docker container.

Super easy to get started (assuming you have Docker installed on your machine), create a Dockerfile with the following content:

A new Java runtime was announced for Google App Engine standard: with Java 11. It’s currently in beta, but anybody can already try it out. Another interesting announcement was the fact that the instances running your apps now get double the memory! So with this double dose of great news, I decided to craft a little tutorial to show how to deploy a Micronaut application on App Engine Java 11. And because Apache Groovy is, well, groovy, I’ll go ahead and use Groovy for my programming language, but of course, the same steps apply to Java workloads as well.

A few weeks ago, I had the chance to be at Devoxx Belgium once again, to meet developers and learn about new things from awesome speakers. Google Cloud Platform had its own booth on the exhibition floor, and the team was running codelabs: 10 laptops were at the disposal of attendees to go through various hands-on tutorials on several GCP products. I took a chance at crafting my own codelab: deploying a Micronaut application, containerized with Jib, to Google Kubernetes Engine.

Back to GR8Conf Europe in Denmark, for the yearly Groovy community reunion! I had the chance to present two talks.

The first one on Google’s Machine Learning APIs, with samples in Groovy using vision recognition, speech recognition & generation, natural language analysis. I’ll come back on ML in Groovy in forthcoming articles.

And the second talk was an overview of Google Cloud Platform, focusing on the compute and storage options, with demos using Groovy frameworks (Ratpack, Gaelyk, and the newly released Micronaut) and how to deploy apps on Compute Engine, Kubernetes Engine, App Engine. I’ll also come back in further articles on those demos, but in the meantime, I wanted to share my slide deck with you all! Without further ado, here’s what I presented:
