#WorldInnovationDay Hack Information Pack

We are providing to each participant access to Oracle Cloud Infrastructure (OCI) for the hackathon. The following resources are to make you effective with OCI.

Oracle Cloud Infrastructure

From past hackathons, we noticed a trend of what technologies and services are being used by the winning teams. Here are the top resources with some additional references.

  • For a single platform to store JSON, Graph & Spatial, perform ML or deliver Low-Code Apps, use Autonomous Database (here)
  • For establishing infrastructure with your OS of choice, use OCI Compute (here)
  • For Jupyter notebooks and ML packages, use Data Science Cloud (here)
  • For quick self-service and data visualisation, use Analytics Cloud (here)
  • For making sure everything is secured, use Oracle Security (here)
  • For most things you need for #AppDev, use Oracle AppDev (here)
Live Labs

You will need to learn quickly. These hands-on workshops will help you learn more about the services available.

  • For those who are interested in a single platform to store data (here)
  • For those who want to #lowcode (here)
  • For adding Blockchain to your datasets (here)
  • For those who are interested in data science (here)
  • For ML on datasets in the database (here)
  • For data storytelling with data visualisation (here)
  • For building microservices applications (here)
Next Steps

There will be a series of workshops where we will be present on different OCI topics in the week leading up to the hackathon. Make sure you have these in your calendar so you don’t miss out.

And reach out on the #WorldInnovationDay Hack 2021 Slack workspace if you need anything from the team.

Serverless on Always Free Tier with fnproject

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).

Teaching How to Get Started with Oracle Container Engine for Kubernetes (OKE)

In a previous blog, I explained how to provision a Kubernetes cluster locally on your laptop (either as a single node with minikube or a multi-node using VirtualBox), as well as remotely in the Oracle Public Cloud IaaS. In this blog, I am going to show you how to get started with Oracle Container Engine for Kubernetes (OKE). OKE is a fully-managed, scalable, and highly available service that you can use to deploy your containerized applications to the cloud on Kubernetes.

Teaching How to Invoke Gen2 Oracle Cloud Infrastructure (OCI) resources via REST APIs

I am thrilled with the Oracle’s Gen2 Cloud Infrastructure architecture, where Oracle completely separates the Cloud Control Computers from the User Code, so that no threats can enter from outside the cloud and no threats can spread from within tenants.

Obviously with more security, there comes more coordination, especially at the moment of invoking OCI resources APIs. Luckily, Oracle did a good job at providing a simple to use CLI and SDK (see here for more information).

For the purpose of this blog, I built a simple NodeJS application that helps demystify the security aspect of invoking OCI APIs. Check this link for examples of running similar code across other Programming Languages.

My NodeJS application manages OCI resources in order to:

  • List ADW instances
  • Stop an ADW instance
  • Start an ADW instance

I started this NodeJS application to list, start and stop ADW resources. However, I designed this application to easily extend it to invoke any other type of OCI resources.

I containerised this application with Docker, to make it easier to ship and run.

This is a picture of the moving parts:

Teaching How to Get started with Kubernetes deploying a Hello World App

In a previous blog, I explained how to provision a new Kubernetes environment locally on physical or virtual machines, as well as remotely in the Oracle Public Cloud. In this workshop, I am going to show how to get started by deploying and running a Hello World NodeJS application into it.

There are a few moving parts involved in this exercise:

  • Using an Ubuntu Vagrant box, I’ll ask you to git clone a “Hello World NodeJS App”. It will come with its Dockerfile to be easily imaged/containerised.
  • Then, you will Docker build your app and push the image into Docker Hub.
  • Finally, I’ll ask you to go into your Kubernetes cluster, git clone a repo with a sample Pod definition and run it on your Kubernetes cluster.

Teaching How to use Oracle Load Balancer as a Service (LBaaS) to front end your APIs

In this blog, I am going to show you how to configure Oracle Load Balancer as a Service (LBaaS) to proxy/redirect traffic into multiple APIs. For the sake of this example, I am going to point to running APIs hosted on my Oracle API Gateway, as well as running on a 3rd party Cloud provider. However, you can use Oracle LBaaS to proxy traffic to any HTTP or HTTPS endpoint(s).

In this example, I am going to consume an existing API that I built some time ago that when invoked returns a random joke. In order to test it in high availability mode, I am also going to configure yet another “jokes” API that will serve as a redundant backend endpoint/API.

This is the high-level view of how Oracle LBaaS can easily enable multiple proxy/redirections to backend APIs hosted across various places:

Experimenting with Fn project

The first AppDev Made Easy (previously known as DX Workshop) for this tour started in Perth. We are continually trialing a few different things as such as we incorporated Fn project https://fnproject.io.

The whole demonstration of Functions was to articulate that there are different ways to execute and understanding the problem to solve as well as the values that the organisation holds (including both business and IT departments including developers) which will determine the technology.

For the demo we start from the very beginning.

Teaching best practices to Design, Build, Secure and Monitor APIs

In this blog, I want to share my experience after having created many APIs using different approaches and technologies. I am going to encapsulate a simple process that will help you construct APIs, starting from scratch with an idea or requirement and move it all along to a happy consumption.

The best part of APIs is that they are microservices enablers, which implies that they are not technology prescriptive, so in this blog you will see that your APIs can be implemented using any technology or programming language.

I decided to use “Jokes” as the vehicle to explain the APIs construction best practices, mainly because jokes are a simple concept that anyone can relate to, but also because I want you to feel compelled to consume these APIs and by doing so, get a laugh or two.

My original idea with jokes is to:

  1. Get a random joke.
  2. Translate the joke to any language.
  3. Share the original or the translated joke with a friend via SMS.

This is the high-level view of how our end solution will look like:

It’s an Adaptive and Emotional World

designingproductsforadaptabilityetceventbritepicture

Last week I had the opportunity to pop into QUT Foundry and attend an event called Designing Products For Adaptability, Innovation & Sustainability. It was a great experience and there were lots to learn about it. The guest speakers included Prof. Tyson Browning from TCU visiting from Texas and Dr. Rafael Gomez from QUT. It was an opportunity that I embraced to meet new people and be part of a growing community.
