OpenDaylight Summit 2016: Apache Karaf Report

My talk submission to OpenDaylight Summit 2016 was accepted! I'm very excited to have this opportunity to address the OpenDaylight community directly this Fall in Seattle. If you're attending the conference, please feel free to sign up for my talk on Sched (http://sched.co/7RBf).

Abstract: OpenDaylight's Apache Karaf Report:

Apache Karaf is at the core of any OpenDaylight system; the architecture and capabilities of Apache Karaf will, in the end, place an upper bound on what OpenDaylight can do as a whole. In this presentation, Jamie Goodyear will review recent events in the Apache Karaf development community, discuss the current state of Apache Karaf and its sub-projects, the challenges it faces, and look forward to how Apache Karaf may address those challenges.

What does OpenDaylight SDN Platform need from the Apache Karaf container?

Just wanted to share my talk from OpenDaylight Summit 2015.

I'd like to thank the OpenDaylight community again for allowing me speaking time during the developer forum.

Decanting OpenDaylight

The Monitoring and Alerting Solution for Apache Karaf
During OpenDaylight Summit 2015 I was given the opportunity to talk about Apache Karaf's road map, and Karaf's new subproject Apache Karaf Decanter.

Decanter is a complete monitoring and alerting solution for Apache Karaf.  It provides a web based collection of dash boards, which contain nicely graphed metrics from your applications' runtime, and lets you explore logged events.

Architecturally, Decanter is composed of:
  • collectors retrieving monitored data (JMX metrics, log messages, etc)
  • dispatchers powered by EventAdmin, and
  • appenders storing monitored data.
Decanter provides a Service Level Agreement layer, which allows you to check values of harvested data and send alerts when data in not in the expected state.

User and Developer guides are available from Karaf's website.

OpenDaylight Lithium, Decanted
Perhaps the most exciting news for OpenDaylight users is that the core Decanter framework works on Lithium! All the OpenDaylight community needs to do now is develop the various collectors, dispatchers, appenders, and alters to make OpenDaylight based services appear in one of Decanter's dashboards.

Thank you ODSummit

George Zhao, OpenDaylight Release Manager
receiving a signed copy of Learning Apache Karaf
I recently attended OpenDaylight Summit 2015 in Santa Clara, California - a community gathering of the developers, and users of OpenDaylight SDN Platform. The energy and enthusiasm of the crowd for building this new open source community was invigorating. I met many of the people behind the IRC nicknames I've come to know over the last year & half of working with the community. It was truly a great event, and I look forward to seeing how OpenDaylight's next release, Be, evolves.

The various keynotes, sessions, and tutorials are available for reviewing from the OpenDaylight projects' youtube channel. I'd like the share the below two keynotes, as it helps show how deeply OpenDaylight is reaching into today's networks and how integral OpenDaylight (and it's Apache Karaf core) is becoming in tomorrow's infrastructure:

Security BSides St John's 2015 Call for Papers is Open

BSides St. John’s 2015 is happening on September 25th, and will consist of a single speaking track. Regular presentation slot lengths are a fixed duration of 45 minutes plus 15 minutes for Q&A if necessary. For 2015, BSides St. John’s is also accepting submissions for Lightning Talks. They will be limited to 10-15 minutes in duration and typically consist of 2 to 3 presentation slides. We are hoping that this short presentation time will encourage those new to presenting to submit.

We are currently investigating our options to live stream the event and record all presentations for later distribution. If the recording and live streaming of your presentation poses an issue for you then please contact us to discuss your concerns.

It is important to note that any presentations or talks deemed to be of a marketing or sales pitch nature will be politely rejected.

Submissions will be in plain text and should address the following points

  • Your preferred email address
  • Are you representing anyone (yourself, company name, group name)
  • The title and abstract for your presentation
  • Approximate length of your presentation

Additionally, your submission should answer the following questions:

  • Has this material been presented elsewhere? If so, where and when?
  • May we record and stream your presentation? If not, why?
  • Will you be travelling to the event? If so, from where?

Submissions must be emailed to BSidesStJohns@gmail.com. The CFP opens on July 1st and the deadline for submissions is September 10th. A confirmation of receipt of your submission will be sent within 48 hours. A follow-up email, if required, will be sent to you requesting further information or clarification.

Using OpenCL on OpenDaylight

GPU processing on OpenDaylight!
I've been preparing for OpenDaylight Summit 2015, the yearly gathering of the OpenDaylight SDN community for tutorials, keynotes, sessions, and design forum. I wanted to build a little demo or two that I could run while on the conference floor. The first one is KTop: the Karaf Top processes command, the second is a small OpenCL on OpenDaylight demo.

OpenCL allows developers to construct kernel functions that execute on OpenCL capable devices - such as your GPU. Given there are a few use cases where massively parallel computing on a GPU could drastically reduce processing time, having OpenCL made available to applications running on OpenDaylight could be interesting.

My demo is just a proof of concept at this stage, however I'd enjoy discussing what could be made of the underlying concepts. That being said, I'd also love to chat about how OpenDaylight can make more use of its Apache Karaf container, and how we at Savoirtech can help organizations develop and maintain their Karaf-based applications.
