OCI Arcade Now Has A CRM

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.

Bastion Access For Minecraft

In the previous post, I did some work in managing Security Lists to protect the Minecraft Server. To read about that, head (here). Another method of connecting to the Minecraft Server is through a Bastion Host. As part of Oracle Cloud Infrastructure, it is free to create a session through the Bastion Service (service limits do apply). Here’s a brief encounter of getting this up and going.

#DaysOfArm (14 of X)

This is my 14th #DaysOfArm article that tracks some of the experiences that I’ve had so far. And just to recap from the first post (here) on June 12 2021.

It’s been just over 2 weeks since the launch of Ampere Arm deployed in Oracle Cloud Infrastructure (OCI). Check this article out to learn more (here). And it’s been about one week since I started looking into the new architecture and deployment, since I started provisioning the VM.Standard.A1.Flex Compute Shape on OCI and since I started migrating a specific application that has many different variations to it to test it all out.

This is my next learning where I’ve deployed successfully openrouteservice – an open-source routing / direction API all deployed on an 4 OCPU with 24 GB of RAM in an Always Free Tier tenancy.

Minecraft On OCI Arm (Plus)

Over the weekend, I took some inspiration from a few different sources and put this together in action. Taking what Todd Sharp has mentioned on his blog (here) and what I’ve been doing with my #DaysOfArm article series (most recently here) and some of the things that I’ve been doing at home with learning how to code – then this is what’s been able to be achieved and some learnings and differences that I’ve taken with running Minecraft (on Arm).

Welcome To The OCI Arcade

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.

We welcome you to the OCI Arcade

Free WordPress on OCI

GOT EASIER … with Oracle Resource Manager

I’ll keep this short … I recently came across an update to one of the Oracle Cloud Infrastructure Quick Starts for WordPress. The specific addition that caught my eye was a micro deployment of WordPress – 1 x VM and 2 x Docker images (check out the repo here). I looked at that and thought:

This Terraform package would be good for Always Free Tier

Which it was, downloading the repository and created an Oracle Resource Manager Stack (learn more here) and applied the stack. And within minutes, I had a working instance of WordPress.

Yes – it is a single instance.
Yes – I could have built something that was more secured.
Yes – I could have built something that was more scalable – using MySQL Database Service or Oracle Kubernetes Engine.

But putting this altogether, I spent less than 10 mins on this and I can get going. And it is Always Free. The nice this is that I know that this model can expand as it requires (and only when I need to).

I thought about this for the upcoming hackathon too #WorldInnovationDay (https://hackmakers.com) where people are wanting a site to display their solutions. This is a way of doing it and keep it as part of their portfolio.

If you need an environment to try this out – head to the following link and sign-up. https://www.oracle.com/au/cloud/free/. If you are part of the hackathon, we are giving participants a promotion with $500USD credits into a new tenancy and no credit card. Try this out for yourself.

Free In-Memory Data Grid

Here’s the architecture of the OCI Arcade extended with Coherence-CE

I was talking to Tim Middleton who works in the Coherence Development team the other day about different scenarios that we can work on some areas that demonstrate the scale out – two scenarios were obvious (to me) – Apache Spark was one and the other was Coherence – an In-Memory Data Grid.

And with that I built out the OCI Arcade to bring Coherence-CE (Community Edition) into the mix. There’s some lots of cool stuff that you can do with Coherence-CE and the bulk of the content is (here).

To get access to the OCI Arcade with Coherence – you can find these on a git branch in the repositories.

The simple use-case that we used Coherence-CE for was a simple identity key for the instance id (ie each game plays has a unique identifier). The nice thing was that it was all in Javascript. This following fragment was the only thing that I needed to do to integrate Coherence-CE into the app itself.

const opts = new Options()
opts.address = 'oci-cache:1408'

app.get('/id', (req, res) => {
  var game_id = req.query.game_id;
  var session = new Session(opts)
  var map = session.getMap('oci-id')
  setImmediate(async () => {
    console.log('Map size is ' + (await map.size))
    if ((await map.has(game_id)) == false) {
      await map.set(game_id, { id : 1 })
      res.send('{ "id" : 1 }');
    } else {
      res.send('{ "id" : '+(await map.invoke(game_id,Processors.increment('id',1)))+' }')
    }
    await session.close()
  })
});

From the Coherence-CE cluster perspective – there’s docker images from docker hub already (here) that I could use for it. So replacing what I did previously with Kafka in the deployment architecture and putting Coherence-CE in its place was simple. (NB: There were some changes in terms of stopping events being fired to Kafka and also creating the instance id from this method instead of a Date.now() method. Simple things).

There’s plenty of different directions that we can go from here – session-based cache scenarios, high-availability scenarios, in-memory data processing scenarios. There are plenty to extend and learn from.

If you want to try this out yourselves, you can get an Always Free Tier environment – head to the following link and sign-up. https://www.oracle.com/au/cloud/free/.

To get the whole thing up and running, then head to this previous blog to see how to get the OCI Arcade up and running (and playing) – https://redthunder.blog/2021/02/12/automating-with-oci-oracle-resource-manager/. Remember – use the coherence-ce branch.

I acknowledge Mason Borda for their contribution in building this game.

Have fun learning, experimenting and if you want to contribute to any of these things – reach out. #CommunityMatters #ItTakesAVillage

Oracle MFT – OIC Integration

Even in a day and age where event-based and real-time data exchange is prevalent and growing, the truth is there are still massive amounts of data exchanged using file transfer mechanisms.  Oracle has always played in this realm, but with limited success.  The Oracle Managed File Transfer (MFT) application is pretty good, but nothing to write home about… or write a blog about! 😀

One reason is because moving files around and using FTP servers is not very glamorous.  Another reason is because the Oracle MFT management dashboard is pretty limited.  It is able to monitor various aspects of a file transfer, report success or failure and allow you to resend files.  But it has no business context or the ability to understand how a file might be part of a larger business process.
