Last week, I wrote about how to get started with the PaLM API in the Java ecosystem, and particularly, how to overcome the lack of Java client libraries (at least for now) for the PaLM API, and how to properly authenticate. However, what I didn’t explain was what I was building! Let’s fix that today, by telling you a story, a kid story! Yes, I was using the trendy Generative AI approach to generate bedtime stories for kids. Read more...

Large Language Models (LLMs for short) are taking the world by storm, and things like ChatGPT have become very popular and used by millions of users daily. Google came up with its own chatbot called Bard, which is powered by its ground-breaking PaLM 2 model and API. You can also find and use the PaLM API from withing Google Cloud as well (as part of Vertex AI Generative AI products) and thus create your own applications based on that API. Read more...

In this article, let’s revisit the topic of deploying Java apps on Cloud Run. In particular, I’ll deploy a Micronaut app, written with Java 17, and built with Gradle. With a custom Dockerfile On Cloud Run, you deploy containerised applications, so you have to decide the way you want to build a container for your application. In a previous article, I showed an example of using your own Dockerfile, which would look as follows with an OpenJDK 17, and enabling preview features of the language: Read more...

Time to spill the beans and show the gems, to our friendly snakes and elephants: we’ve got some great news for Java, Ruby, Python and PHP serverless developers today. Google App Engine and Cloud Functions are adding new modern runtimes, allowing you to update to the major version release trains of those programming languages. In short, here’s what’s new: Access to App Engine legacy bundled services for Java 11/17, Python 3 and Go 1. Read more...

One year after Google App Engine was released in 2008, Java became the second language runtime available on the platform. Java developers were able to deploy and scale their servlet-based web applications easily, without worrying about infrastructure management. Not only Java was able to run then, but alternative JVM languages, like Apache Groovy, and Kotlin are also part of the game. Fast forward to today, we’re pleased to announce that the Java Runtime for App Engine is now available as open source, in the GoogleCloudPlatform/appengine-java-standard repository on Github.

As I was working with my colleague Sara Ford on testing the Cloud Functions runtimes for the upcoming “second generation” of the product, rebased on the Cloud Run platform, I wrote a few simple functions for the Java runtime. In one of those Java functions, I wanted to use Google Cloud Storage, to download a file from a bucket. I took a look at the existing sample to download an object: Read more...

For the 24 hours of talks by Google Cloud DevRel, I recorded my talk about the new Java 11 runtime for Google Cloud Functions. I wrote about this runtime in this article showing for example how to run Apache Groovy functions, and I also wrote about it on the GCP blog and Google Developers blog as well. In this video, I’m giving a quick explanations on the serverless approach, the various serverless options provided by Google Cloud, and then I dive into the various shapes Java functions can take (HTTP and background functions), the interfaces you have to implement when authoring a function.

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.
