#ThankYou To The Mentors

At the #WorldInnovationDay Hackathon, Apr 16-19 saw many participants and teams come together to progress the agenda around the United Nations #SustainableDevelopmentGoals. I’ve previously wrote about this hackathon – you can check these articles about the technology (here) and about the event (here).

#WorldInnovationDay Tech Showcase

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.

#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.

Each Little Bit Helps …

If you had come here because of the link in the information pack, great. If you have come here because you found this page through other means – read on and if you are inspired to contribute (on April 16-19) – head to the Hackmakers site (here) to register for this event.

Not Just Another Workshop

In closing out 2020 and before going on leave, I was given an opportunity (never a challenge). And it came in the form of these Oracle Code Cards. For those that haven’t seen them, this is what they look like and here is a git repository of some code explaining more about the cards themselves that I’m revamping – https://github.com/jlowe000/codecard.

An trial using the Oracle Code Card before the workshop.

The outcome required was as open as I could get.

There were no boundaries and there were no specific rules.

#DigitalDefence – The Infinite Game

Last weekend saw over 2,000 people participate in the #DigitalDefence Hackathon hosted by Hackmakers, Oracle as the lead sponsor plus a vast range of other sponsors – ITIC, AustCyber, NASSCOM CoE, Cyber Security Centre of Excellence, IBM and community partners – Public Sector Network, Slack, Black Nova Group, Yirigaa, UNSW DataSoc, SLASSCOM, DataCated Academy and DataEthics4all.

This event was off the back on #BuildWithAI Hackathon hosted by Hackmakers. Being a contributor to that event as a Lead Mentor, Sponsor and a Challenge Organiser, there was something there that resulted from what we were able to deliver – another step in the infinite game. (Note – I haven’t read the book, I don’t follow Simon Sinek however from different communities and framework where we focus on growth mindsets, long tail and talking about your why – this is another example of that same conversation).

This is another step in the infinite game.

Circuit Breaker in Service Mesh – Istio/Envoy

This Lab, logically follows previous steps required to provision and curate a Kubernetes cluster. Please review them before proceeding. If you are in doubt, feel free to contact me directly via https://www.linkedin.com/in/citurria/

Testing BookInfo app with Circuit Breaker based policy

The third and last test in the Service Mesh, is using a Circuit Breaker based pattern. It further protects our microservices in case of certain conditions occur, such as preventing that an unexpected number of requests overflow and affect the microservices in the service mesh.

We might decide to throttle or simply reject new incoming requests when a number of current incoming http requests reaches certain threshold.

For demonstration purposes, we are going to set rules to allow a maximum of 1 request at a time. If more than 1 request comes in, we will prevent it from entering the mesh.
