Functions in Oracle Cloud Infrastructure are great. As a serverless execution environment with pre-built logging, metrics, etc. it allows developers to simply focus on their code and not worry about all of the supporting infrastructure, while still providing a lot of flexibility through the use of container primitives. As great as Functions are, they are reactive, they can only be invoked and can’t natively be configured to be executed in a spontaneous or scheduled manner. Often this won’t matter, as Functions will be invoked directly or indirectly by users, or in response to events, but sometimes you simply need a bit of code to run periodically.Continue reading “A Better Mechanism for Periodic Functions Invocation?”
In this blog post I will explore how we can extend the native capabilities of Oracle Integration (OIC) with Oracle Functions to process Excel files.
Although OIC can handle a number of file formats natively, .xlsx or .xls files need a bit of extra love.
The inspiration for this blog comes of the back of several customer enquiries into this subject.
The simple solution for most customers is to convert the Excel file formats to CSV and subsequently process them with OIC. I will use this approach here too but with a little bit of help from other OCI services such as Oracle Functions, an API Gateway and Object Storage.
A video of this demo is available here.Continue reading “Process Excel files with OIC + Oracle Functions”
I had a meeting the other day with an Oracle Partner and the discussion was about serverless solutions and Oracle Functions was introduced. And the natural question to ask was, “What is your preferred language?”.
They answered, “Mostly PHP. We also use C#”.
I had to think a little. And navigating to the fnproject.io (the open-source project that Oracle Functions is based upon), it was clear that C# was supported. Here’s a quick tour through that experience.
A couple of quick points:
- I didn’t need to install ASP.Net anywhere.
- I’m not bound by Windows as the host operating system.
And if ASP.Net is your language of choice, you can also check out Deploy highly available ASP.Net applications on Oracle Cloud Infrastructure in the Oracle Architecture Center (here).Continue reading “C# Serverless on OCI”
As each project comes along, there’s something new to add to the OCI Arcade. It started off with the game and Autonomous Database. And then grew into including Kafka, Docker Swarm, Serverless with the FN Project, Terraform, OAuth, Ansible, In-Memory Data Grid with Coherence-CE and more recently with Arm. This time round we’ve adding in a Customer Relationship Management (CRM) solution. Why? Up to now, users has been a simple identifier to denote the scores and the events in the game. Nothing more; nothing less. By adding in a CRM into the mix, we’ve opening up the understanding about our contacts and customers providing a richer experience for those coming to the arcade. And ultimately, from a space where we are build, experiment and try something out – adding user profiles opens up endless possibilities. Check out the rest of this about how it’s changed and some of the things we needed to do to make this happen.Continue reading “OCI Arcade Now Has A CRM”
You can also watch it (here) too with Clay Magouyrk, Executive Vice President, Oracle Cloud Infrastructure. Note: The link above has more content and videos.
Have you seen the OCI Arcade? We have built the architecture deployable on OCI Always Free Tier.
Recently in the OCI Always Free Tier, an additional services has been added to include 4 cores and 24 GB of RAM of Ampere A1 Compute. With this additional capacity, it made sense for OCI Arcade to be ported to this A1 Compute Shape. Here is what we did and why.Continue reading “Get OCI Arcade Free on Arm”
Each of us will read this from our own perspective. Equally diverse are the outcomes and the actions that you might want to take away from this. So, I ask you: Be open. Find the opportunity. And execute.
This is something that we’ve built for the purposes of an infrastructure demonstration of Oracle Cloud Infrastructure (OCI). The code is available in an open public github repository and we’ve written articles on specific capabilities. We are open to collaborate in building more scenarios which allows this demonstration to scale.

April 16-19 saw people from across the world come together to focus on three Sustainable Development Goals (SDGs) at the #WorldInnovationDay Hackathon. This blog highlights the technologies used to help accelerate the team’s execution. If you want to read more about the event itself – check out this previous blog (here).
Over the course of the weekend, Oracle Cloud tenancies with $500 USD credits were provided to each participant to use. It was not mandated that they use Oracle Cloud nor was it given to participants automatically. It was encouraging to see people open to explore and learn with Oracle Cloud. I want to thank the Oracle mentors supported the participants ensuring that whilst the teams explored, they could confidently execute and deliver. Here are the common requests from teams and the cloud services that they used over the weekend.Continue reading “#WorldInnovationDay Tech Showcase”
I’ve started posting articles related to the project that @stantanev and a few of us are working on. This is snapshot of the puzzle that is to build out a APIs on the Oracle Always Free Tier.
As a demonstration of capability, we built a few different APIs using fnproject (https://fnproject.io/) – an open-source container-native serverless platform. As part of Oracle Cloud Infrastructure, there’s Oracle Functions which is the managed Function-as-a-Service based upon this same project.
Let’s take a look at it here and see what it took to get going. Also, this is being deployed into VM.Standard.E2.1.Micro compute shapes (which is 1 OCPU and 1GB of memory) and hence there are some considerations to make sure we get the most out of the kit we have access to (for free).Continue reading “Serverless on Always Free Tier with fnproject”
Between the Oracle Cloud Infrastructure (OCI) Audit Service recording administrative operations and Oracle Identity Cloud Service (IDCS) tracking access and user management events, Oracle Cloud provides pretty comprehensive tracking of security events. Recently however, I have been in conversations with a number of organisations who have been seeking longer term retention of audit events for several different reasons, including governance, compliance and forensic requirements. The OCI Audit service supports requesting bulk export of audit events to Object Storage, which allows you manage the retention and archiving of those events yourself, so I started wondering if I could do the same for the IDCS access events. A bit of testing and some simple coding later, and I had events being pulled directly from the IDCS Audit Events API periodically and sent to Object Storage for retention.
In this blog post, I will provide this code as a sample, and discuss some of the techniques and technologies that are available in Oracle Cloud Infrastructure to enable simple, but highly secure and cost-effective, automation of cross-service tasks such as this.Continue reading “Simple, Secure Log Retention using OCI Services”
Oracle Cloud Infrastructure provides a ton of useful services for automating and orchestrating behaviours in your cloud environment, and while they are often pretty handy on their own, leveraging them together gives almost complete flexibility on what you can achieve. Want to trigger a backup using a command in slack, then have a message get sent back when it completes? Sure! Want to periodically poll a log API and archive the results? Easy. Oracle Cloud Infrastructure provides a number of inbuilt capabilities, as well as the ability to jump into arbitrary code to build elaborate automation flows, and this blog post will focus upon the security constructs around this, looking at how services can be authorised to invoke one another, as well as how they authenticate themselves, while avoiding storing sensitive data in insecure ways. This post is intended as an overview of the concepts, and will be referenced in more concrete ways in future.Continue reading “Secure Inter-Service Communication in OCI”
