Devoxx 2017 Presentation: Serverless Architectures (AWS Lambda + Fn Project)

Devoxx 2017 in Casablanca has come to an end. I enjoyed this fabulous conference a lot. Highlights were the the Serverless presentations, the istio presentation by Google, the Spring people live coding, and the Kotlin session that showed that my own Kotlin in the cloud HelloWorld was not so bad after all. Tech content is one important part, but also the great atmosphere and focused but relaxed environment with superb lunches were something to write home about.

And here is my presentation:

Video recording doesn’t seem to be uploaded on Youtube yet. Fun fact: We almost bought a flying carpet after Devoxx in Casablanca!

With the same slideset I gave my Serverless presentation at DOAG 2017 conference. Thanks again folks for the marvellous feedback 🙂

Oracle OTN Tour 2017 Sao Paulo: Getting Started with Java Cloud Service (JCS)

At the 2017 OTN stop in Sao Paulo I did my first presentation to help customers to get started with Oracle Java Cloud Service (JCS).

 There are  actually a few showstoppers that make customer’s experience more difficult than it should be in my opinion. I will blog about them later in autumn – for now please have a look at my presentation on Slideshare.

 

SOALatam Conference 2015 in Lima Review

whole_group

Now that the SOALatam Conference 2015 in Lima is over and work slows down a bit because Christmas is approaching it’s time for a summary. To conclude it was one of the best conferences I attended in 2015. You may ask why I favour SOALatam over the others and there are several reasons:

  • It’s vendor independent.
  • It’s cross technology.
  • Although it is cross technology, it is focusing on new developments, such as Docker, microservices and API Management.
  • It’s small but high quality. Good to fit into one single day!
  • There are brilliant people speaking from major companies such as ThoughtworksS&P Solutions but also independently working folks like Thomas Erl and me 🙂
  • There is a max of 2 parallel tracks (and one is more business oriented), so you never miss out a lot.

audience

I personally enjoyed it because I met a new bunch of colleagues. My presentation was about Linux Containers Docker: Thorough and Critical Overview, covering Docker security, Docker Swarm, Docker Compose and Docker Networking including some predictions for the future. Also I discussed some challenges that show up in a Docker environment when running non 12-factor applications such as Oracle WebLogic Server.

OTN Tour Latin America 2015: Colombia

col goldColombia was my last stop on the OTN tour, yet it was the country I was waiting for. I had good memories about the country from many years ago when I was backpacking there and it was a pleasure to see how everything has changed.

I decided to take a hotel in the north which is closer to the some shopping malls and various museums. At night after arrival I got a local SIM card which was a breeze and cost less than 10€ for 1 GB of data. First day I nipped out, crossed the main street to the Alcaldía and headed straight to the Museo del Oro Calima (Gold Museum).

The conference was organized by charming Giovanna Bohorquez Paez and her team from the Asociación de Usuarios Oracle de Colombia. Everything went swimmingly and I felt flattered to give a Docker and WebLogic presentation at the Universidad Autónoma de Occidente. Due to some changes there was no time left for my 12 Things about WebLogic 12c presentation but feel free to download the presentation slides. For the first time I had the pleasure to meet Mauricio Naranjo in person. During the coffee break we had a exotic looking but surprisingly well tasting drink called Champús (check this wiki link for a pic!).

Altogether I enjoyed the conference a lot. It was a great atmosphere, people came to ask questions and to have their pictures taken together with us. To respect their privacy I put a picture of us below.

At the end, I decided to stay an extra day, visited some lookouts and local bars with a friend who also gave me a lift to the mountain range called KM18. Calenos love to go there because it is much cooler, so it is really crowded on Sundays. There I had an even stranger but also even tastier (!!) drink called agua de panela (sweet hot drink made of sugar cane) with savory cheese in it. Loved it!
