Fire and forget messaging is a powerful concept. Asynchronous, decoupled communication is key to scalability and independence of services. Oracle Cloud provides a pub/sub solution called Oracle Messaging Cloud Service. This is an HTTP based publish and subscribe mechanism for asynchronous communication – based on persistent messages and durable subscriptions. […]

Publish Oracle Function for Reading and Writing Object Storage Files through OCI API Gateway
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 allow easy writing to a file on Object Storage and easy retrieval of such as file. Writing files is obviously useful […]
Oracle Cloud Infrastructure – Leveraging API Gateway as Read Only Cache from serverless Function
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 API Gateway and ask the serverless function for values that are read from a [read only] cache. This cache is […]
Oracle Cloud API Gateway – Using an Authorizer Function for Client Secret Authorization on API Access
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 Client Secret is included. The Authorizer Function does a little more than simply accept or deny: in case of accept it […]
Oracle Cloud Serverless Functions unleashed: exposing OCI Functions through API Gateway
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 publicly accessible can be given such easy access. By creating an API Deployment on an API Gateway and associating a route […]
Scheduling Oracle Cloud Function execution
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 specific tasks. These tasks can be executed upon reception and handling of HTTP requests – a very common use case – […]
My Quick Start with Oracle Functions in Fresh OCI Tenancy
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 myself, for future reference. However, my description could prove useful to you – the reader. My steps to get going are […]
My first steps with Oracle Cloud API Gateway – the stock response
The API Gateway service on Oracle Cloud Infrastructure went live very recently – read my overview article of what API Gateway entails. In brief: API Gateway is a reverse proxy that exposes HTTP endpoints on which external (or internal) clients can make requests. API Gateway can handle these requests: authorize, […]
Introducing Oracle Cloud API Gateway – the light weight public or private router to public and private OCI endpoints
Two days ago, the API Gateway service on Oracle Cloud Infrastructure went live – read the announcement. This is a crucial component for many applications and in many solution designs. This new API Gateway is a prime candidate for example for inclusion in our reference architecture for OCI based solution […]
Oracle Integration Cloud pricing explained – OCI vs Classic
Last week at AMIS we had the task of estimating costs of a proposed iPaaS solution for one of our customers that runs on a fully managed cloud. As AMIS is mainly an Oracle partner we looked at how competitive we could make the pricing of the solution using Oracle […]
Changing the configuration of an Oracle WebLogic Domain, deployed on a Kubernetes cluster using Oracle WebLogic Server Kubernetes Operator (part 2)
At the Oracle Partner PaaS Summer Camp IX 2019 in Lisbon, held at the end of August, I followed a 5 day during workshop called “Modern Application Development with Oracle Cloud”. In this workshop, on day 4, the topic was “WebLogic on Kubernetes”.

Loading Data into Always Free Oracle Autonomous Data Warehouse Cloud – from JSON and CSV to Database Table
In a number of recent articles, I have described how to provision an instance of Oracle Data Warehouse Cloud in Oracle Cloud’s Always Free tier. I have also described how to connect both SQL Developer and Data Visualization Desktop to this ADW instance. In this article, we take this one […]
Oracle Data Visualization Desktop Connecting to Oracle Cloud Always Free Autonomous Database
Oracle Cloud now offers the Always Free Tier that comes with an always free Autonomous Data Warehouse (up to 20 GB data storage) as well as an free Autonomous Database for Transaction Processing. In an earlier article, I described how to provision your own Free Autonomous Data Warehouse in Oracle […]
Connect local SQL Developer to Oracle Cloud Autonomous Database (Always Free Tier)
In a recent article I described how to provision an instance of Oracle Cloud Autonomous Data Warehouse in the recently launched Always Free Tier of OCI. This article shows how to connect from SQL Developer (desktop tool) to this instance. Note: connecting from SQL Developer is the same [of course] […]
Oracle Cloud Always Free Autonomous Data Warehouse – steps to get going
Last month, Oracle announced it’s Cloud Free Tier on Oracle Cloud Infrastructure (OCI). This free tier offers several services (compute, storage, network, monitoring & notifications, serverless functions and Autonomous Database. Two autonomous database instance can be provisioned and leveraged in this “forever free tier” – each with up to 20 […]
