ITNEXT Summit 2019: serverless, streaming and cloud native transformations

For the third time in a row I’ve attended the ITNEXT Summit. This year I got a ticket from LINKIT, for which I thank them. It was the best ITNEXT Summit I’ve been at so far.

It started with breakfast. I already had it at home, but I can’t resist a good croissant. Mmm… Where was I? Oh yeah, the summit. In this blogpost I look back on the sessions I attended.

 

Cultivating Production Excellence – Liz Fong-Jones

Liz Fong-Jones about dealing with complexity in production

I’ve been on-call for complex systems in my life, but in the era of containers and serverless things have changed. Some things Liz Fong-Jones spoke about in her keynote did sound familiar, but she discussed how with complex architecures with distributed systems, containers and cloud it is no longer a question of systems being up or down.

Codemotion Amsterdam 2018, day one

Last Friday I almost felt I had to explain a colleague that I don’t always win raffles and lotteries. Because yep, I won another ticket. Again via the Roaring Elephant podcast. It’s pretty worthwhile listening to them, is all I’m saying.

This was a ticket for CodeMotion Amsterdam 2018. CodeMotion is a conference for developers with topics like the blockchain, Big Data, Internet of Things, DevOps, software architectures, but also front-end development, game development and AR/VR.

Starting at Port of Rotterdam per 1 May 2018

Next week (1 May 2018) I will start as a Hadoop specialist/data steward/data custodian/data something something at the Advanced Analytics team at Port of Rotterdam. We haven’t worked out a fancy data something title yet. I’m already working at this team as a consultant. I’ve been involved with security and data governance of the data lake (for people outside Big Data: a data lake is simply a Hadoop cluster).

I feel great when I study

When I started studying Hadoop, Python and machine learning in 2016, I found something out that I didn’t expect. I feel better when I study. When I finished another problem, exam or course, and I stepped outside the house to do some shopping or to go to work, I felt Read more

Dataworks Summit München 2017 – day one

Just left the beergarten party at Dataworks Summit 2017 in München. Okay, let’s see how well I blog after three of these large beers. Luckily I took notes before. Tell me when I start to become incoherent.

So actually for me the summit started yesterday at the Partner day, but today the breakout sessions started. I’ve attended a cool hands-on session on Apache Ranger and Atlas yesterday. These are the new security and governance tools for Hadoop. And I think we can say that the days that you could say Hadoop is largely insecure are about to be over.

The first session today I attended was the keynote of course. I was a little bit late, but it turned out that the second row seats were largely available, so I had a good view of the speakers. A couple of them tried to convince us that (big) data was going to change everything. I already knew that. (more…)
