OCI Functions are powerful components in a cloud native world. Triggered by events and direct requests, these functions are engaged to perform a specific task. Which could be almost …
Project Fn provides a framework for creating and running serverless functions. It is the foundation for the Functions service on Oracle Cloud Infrastructure. Dapr.io is an open source project …
I like to do presentations about a lot of topics. Most of these presentations are recorded and the link to that recording is then shared to people who couldn’t …
Automation through infrastructure as code is the name of the game. And I am a player in that game. In the last few weeks I have spent a lot …
TL;DR – Multi Client Sessions can be facilitated in a fully serverless fashion. Two players playing Tic Tac Toe or Chess, teams collaborating on a document or diagram, an …
Assume a browser based (or desktop electron) stand alone, client side only application. Multiple users are working with that application at the same time, on their own laptops and …
TL;DR – How to create a Function on Oracle Cloud Infrastructure that uses the Playwright library for running headless browser scenarios, for example for Web UI Health Check and …
In June I wrote a blog series about the AWS Shop Example. In this series, I also wrote about X-Ray . I like X-Ray: you can see how much …
Oracle Functions are the Functions as a Service (or FaaS) offering on Oracle Cloud Infrastructure. Functions are the serverless, stateless execution engines that play such an important role in …
Crucial pieces of functionality in cloud native applications is implemented in Functions. In the case of Oracle Cloud Infrastructure specifically, the Functions framework is typically Project Fn and the …
TLDR: This Katacoda Scenario has a live runtime environment with GraalVM 20.1 prepared for you including an easy to click-through step by step scenario that does a live demonstration …
TLDR: query parameters can be retrieved from the Fn-Http-Request-Url header in the ctx parameter passed by Fn to the Node function handling the request; using url.parse() on that header …
We call them serverless and we consider them stateless. Functions on Oracle Cloud Infrastructure (and on other cloud platforms). Of course they are neither. They run on servers. And …
In a recent article, I described how serverless Functions on Oracle Cloud Infrastructure can invoke each other: synchronously and asynchronously. Although asynchronous calls are the desired state, such calls …
OCI allows for cloud native application development, using facilities such as serverless functions, a light weight API gateway, a streaming service for asynchronous communication based on event messaging and …
The objective for this article is to show you how to get to the point where two routes are available on an API Gateway on Oracle Cloud Infrastructure that …
This article demonstrates a set up that is probably mainly of theoretical interest or maybe useful in demonstrations. I describe how we can invoke an OCI serverless Function through …
The objective in this article: create a simple Authorizer Function that checks the Client Secret passed in API calls and allows and denies requests based on whether the correct …
Functions on Oracle Cloud Infrastructure are implemented using Project Fn. A function runs in Docker container. This container has a runtime (for example for Java, Go, Python, Node) and …
Oracle Cloud Infrastructure API Gateway makes it possible to expose OCI Functions on public endpoints that do not require complex signed HTTP requests. Any function that should be easily …
Functions on Oracle Cloud are an important element in any cloud native application architectures. Functions are typically small, well contained and fairly independent pieces of logic to carry out …
This article is fairly rough log of the steps I went through to get going on Oracle Cloud Serverless Functions. It is mainly intended to provide a note to …
The problem Setting up a datastore connection is an expensive process. The amount of available connections is often limited and creating a connection costs precious time – and and …
This article highlights a use case implementation I recently implemented (for a demo session) leveraging Oracle Functions as well as OKE (Oracle Kubernetes Engine), Object Storage and Elastic …
If your tool is a hammer, every problem looks like a nail. Many of us have seen situations where this tunnel vision over time took hold. And for many …
The challenge I describe in this article is quite specific. I have a Windows laptop. I have access to a remote Kubernetes cluster (on Oracle Cloud Infrastructure). I want …
Project Fn is an open source project that provides a container native, poly-language, cloud agnostic (aka run on any cloud) serverless platform for running functions. Fn was launched during …
In a previous article, I described my first steps with Azure Functions – one of the implementation mechanisms for serverless computing: Serverless Computing – Function as a Service (FaaS) …
