Talking about IBM Event Streams

Wednesday, September 9th, 2020

We’ve been running a virtual event this week to explain the capabilities of IBM’s Cloud Pak for Integration.

One of these is Event Streams, so I gave an overview of the Event Streams Operator.

But what it really reminded me is that I miss going to conferences and tech events. I don’t want to sound ungrateful for what I’m sure has been a huge amount of work for event organisers in the pivot to online events. It’s great that we can still do events at all, and that organisers are still trying out ways to make it interactive, to enable panels and Q&A sessions.

Installing IBM Event Streams using the kubectl-operator plugin

Thursday, August 13th, 2020

Installing operators in Red Hat OpenShift from the CLI is much easier with the new kubectl-operator plugin. Here’s an example of how you can use it to install the Event Streams Operator.

Installing operators in OpenShift from the CLI is a little fiddly. It’s possible, but you have to create a bunch of custom resources that aren’t entirely intuitive, like Subscriptions and OperatorGroups.

It’s easy if you’re using the OpenShift Console web UI, as it does this all for you so you don’t need to worry about it. But sometimes you want to do things from the command line. And the new kubectl-operator plugin looks like it’ll make that much simpler.

I had a quick play with it this evening, and it let me get the Event Streams operator running with three commands. (Compare this with the OpenShift Console web UI equivalent in my Event Streams demo video).

IBM Event Streams v10

Tuesday, June 30th, 2020

On Friday, we released the latest version of IBM Event Streams. This means I’ve been doing a variety of demo sessions to show people what we’ve made and how it works.

Here’s a recording of one of them:

In this session, I did a run-through of the new Event Streams Operator on Red Hat OpenShift, with a very quick intro to some of the features:

00m30s – installing the Operator
02m10s – creating custom Kafka clusters in the OpenShift console
05m10s – creating custom Kafka clusters in IBM Cloud Pak for Integration
08m00s – running the sample Kafka application
08m50s – creating topics
10m20s – creating credentials for client applications
11m45s – automating deployment of event-streaming infrastructure
12m30s – using schemas with the schema registry
13m10s – sending messages with HTTP POST requests
13m45s – viewing messages in the message browser
14m00s – command line administration
14m30s – running Kafka Connect
15m10s – geo-replication for disaster recovery
15m50s – monitoring Kafka clusters in the Event Streams UI
17m10s – monitoring with custom Grafana dashboards
17m30s – alerting using Prometheus

This is IBM

Saturday, June 20th, 2020

The “This is IBM” videos are a nice intro to some of the things that we work on at Hursley.

They’re not too technical, they’re not “sales-y” for IBM products, they’re interesting stories, and each one is only a few minutes long.

I also like them as I’ve worked with all of these awesome people before, so it’s fun to see them being all serious on camera – even if it makes me a little jealous that they’re so much better at it than me!

Bringing AI into the classroom

Friday, February 28th, 2020

IBM and mindSpark are running a series of free webinars for teachers about artificial intelligence.

This evening’s 90 minute webinar was about bringing AI into the classroom, and I helped contribute some of the content.

The session was very interactive, but there were some pre-prepared presentations in there.

I’ve got a recording of one of the segments below, in which I shared some of my experiences of introducing AI and machine learning in schools, and what I’ve found works well.

A run-through of IBM Event Streams

Thursday, January 16th, 2020

I needed to quickly record a demo of what it looks like to get started with Event Streams yesterday.

It’s a little rough around the edges (it was only for an internal event, so the production values were essentially me-talking-at-my-laptop without a lot of planning or editing) but I thought I’d share it here in case I need to point anyone else at it.

NASA Space Apps Challenge at Hursley

Sunday, October 20th, 2019

This weekend was NASA Space Apps Challenge again – a weekend space-themed hackathon organised by NASA. It runs around the world, and this year IBM Hursley hosted one again.

I was in a small team with Faith. There were a variety of challenges to choose from and we chose Orbital Scrap Metal which was about educating the public about orbital debris, or space junk – explaining what it is, where it comes from, and the potential impact it has.

We created a game to help kids learn about space debris while playing. It’s fun, educational, and is all driven by real live data about space debris – each time you play, you interact with different real debris items.

Using Node-RED with IBM Event Streams

Friday, June 28th, 2019

IBM Event Streams is the distributed streaming real-time data platform Apache Kafka, from IBM.

Node-RED is a visual flow-based development tool, with nodes that you drag and drop onto a canvas and wire together. It’s useful for loads of tasks, such as quick and flexible prototyping.

In this post, I’ll show how Event Streams and Node-RED work well together. You can use Node-RED to quickly and easily create flows that consume messages from Kafka topics, or that process events from different sources and produce the output to Kafka topics.
