Serverless Node Function on Oracle Functions runs periodically to produce CSV report on Oracle ObjectStorage from data in ElasticSearch

 

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 Search. I will briefly touch upon some of the interesting aspects of implementing this case. The code for the function and its deployment can be found in this GitHub repo: https://github.com/lucasjellema/soaring-logisticsms-shippings-reporter-func .

The next figure illustrates the story of this article: a CSV file is produced (more...)

Invoke an Oracle Function on Oracle Cloud Infrastructure from a Node application

Oracle Functions is currently in limited preview and is expected to soon reach wider availability. Rolando Carrasco did this write up on Medium about his first experiences with Oracle Functions. Oracle Functions is a managed PaaS service, based on Project Fn. It supports a serverless architecture with light weight functions that can easily scale and for which no infrastructure has to be configured or managed.image

Functions can be triggered for execution in several ways: from (more...)

Save File to Oracle Cloud Infrastructure Object Storage from Node through REST API

Oracle Cloud Infrastructure Object Storage is a public cloud service for storing data to which you need fast, immediate, and frequent access. As Oracle states: “The Oracle Cloud Infrastructure Object Storage service is an internet-scale, high-performance storage platform that offers reliable and cost-efficient data durability. The Object Storage service can store an unlimited amount of unstructured data of any content type, including analytic data and rich content, like images and videos.”image

Exposing Kubernetes Services to the internet using Traefik Ingress Controller

Three services have been deployed to my Kubernetes cluster running on a public cloud environment. These services expose port for three underlying Pods and six or so containers. The service make the Pods accessible within the cluster – but not to the outside world, the public internet.image

 

For a number of reasons – including scarcity of public IP addresses, cost of public cloud load balancer instances, decoupling between (the structure/naming/location/availability of) internal resources and (more...)

Moving message threads to different group using the Yammer API

At AMIS we are quite happy users of Microsoft Yammer. Days with 10 or more messages are no exception and since December 2009, we have assembled quite a history of over 8000 message threads. Because we have joined the Conclusion eco system and we will now share a Yammer Network at that level – built with our existing network at its core – , all our All Company messages would become ecosystem wide All Company (more...)

Building a Conference Session Agenda with Oracle APEX – notes on Pivot, Modal Popup and jQuery

AMIS is part of the Conclusion ecosystem of over 20 companies, each with their own specialty and identity. Several times per year, we organize Conclusion on Stage – a conference that spans across the ecosystem. Presenters from most companies under the Conclusion umbrella submit session proposals. Close to 30 sessions are staged in five rooms and close to 200 participants attend these sessions.

I want to provide a Conference Agenda App that offers the audience (more...)

Get going with Project Fn on a remote Kubernetes Cluster from a Windows laptop–using Vagrant, VirtualBox, Docker, Helm and kubectl

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 to create Fn functions and deploy them to an Fn server running on that Kubernetes (k8s from now on) environment and I want to be able to execute functions running on k8s from my laptop. That’s it.

In this article I will take you on a (more…)
