Let’s continue our discovery of Goole Cloud Workflows! Yesterday, we discovered the UI of Workflows. We created our first workflow. We started with a single step, returning a greeting message: - sayHello: return: Hello from Cloud Workflows! A workflow definition is made of steps. But not just one! You can create several steps. In YAML, the structure of your workflow will be something like: - stepOne: # do something - stepTwo: # do something else - sayHello: return: Hello from Cloud Workflows! Read more...

With more and more interconnected services, making sense of their interactions becomes critical. With Google Cloud Workflows, developers can orchestrate and automate such complex systems by creating serverless workflows. In this series of articles, we will learn together how to use Goole Cloud Workflows, and get to know all its features, with short and easy to read tutorials. For our first day, we’ll discover and use the Workflows UI in the cloud console. Read more...

The trend toward splitting a monolith into fine-grained loosely-coupled microservices has its merits. It allows us to scale parts of an application more easily. Teams become more effective on their focused perimeter. However, in a chain or graph of services interacting with each other via message buses or other eventing mechanisms, it becomes difficult to understand when things start to break. Your business processes spanning those services are in limbo. Here starts detective work to find out how to get back on track. Read more...

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. Read more...

The Java programming language recently turned 25 years old, and it’s still one of the top-used languages powering today’s enterprise application customers. On Google Cloud, you can already run serverless Java microservices in App Engine and Cloud Run. Today we’re bringing Java 11 to Google Cloud Functions, an event-driven serverless compute platform that lets you run locally or in the cloud without having to provision servers. That means you can now write Cloud Functions using your favorite JVM languages (Java, Kotlin, Groovy, Scala, etc) with our Functions Framework for Java, and also with Spring Cloud Functions and Micronaut!

With the beta of the new Java 11 runtime for Google Cloud Functions, Java developers can now write their functions using the Java programming language (a language often used in enterprises) in addition to Node.js, Go, or Python. Cloud Functions allow you to run bits of code locally or in the cloud, without provisioning or managing servers: Deploy your code, and let the platform handle scaling up and down for you.

Java celebrates its 25th anniversary! Earlier this year, the Apache Groovy team released the big 3.0 version of the programming language. GMavenPlus was published in version 1.9 (the Maven plugin for compiling Groovy code) which works with Java 14. And today, Google Cloud opens up the beta of the Java 11 runtime for Cloud Functions. What about combining them all? I’ve been working for a bit on the Java 11 runtime for Google Cloud Functions (that’s the Function-as-a-Service platform of Google Cloud, pay-as-you-go, hassle-free / transparent scaling), and in this article, I’d like to highlight that you can also write and deploy functions with alternative JVM languages like Apache Groovy.

I missed this talk from Alexandre Dubreuil, when attending Devoxx Belgium 2019, but I had the chance to watch while doing my elliptical bike run, confined at home. It’s about applying Machine Learning to music generation, thanks to the Magenta project, which is based on Tensorflow. I like playing music (a bit of piano & guitar) once in a while, so as a geek, I’ve also always been interested in computer generated music. Read more...

We all know about HTML 5, right? Well, I knew about some of the new semantic tags, like header / nav / main / article / aside / footer, but I’m still falling down to using tons of divs and spans instead. So as I want to refresh that blog at some point, it was time I revise those semantic tags. Let’s take the little time we have during confinement to learn something! Read more...

Next in my series of videos while doing sports at home, I watched this video from my colleague Tom Greenaway! It’s about modern web game development, and was recorded last year at Google I/O. There are big gaming platforms, like Sony’s PlayStation, Microsoft’s XBox, Nintendo Switch, as well as plenty of mobile games on Android and iOS. But the Web itself, within your browser, is also a great platform for developing and publishing games! Read more...
