IAB-5039 : MQTT: A Protocol for the Internet of Things (InterConnect 2015)PeterNiblett
MQTT is a simple, event-driven messaging protocol designed for use in Internet of Things and mobile applications. It's implemented in IBM MessageSight and MQ, and it is the protocol used by the IBM Internet of Things Foundation. You will hear it mentioned in several of the talks at this conference; and, as it recently became an official standard and is being used more and more in the world at large, you may have heard about it in the press as well. Come along to this unashamedly technical session to learn about what the protocol actually does, and how to program to it in Java, C or JavaScript.

MQTT - A practical protocol for the Internet of ThingsBryan Boyd
In today’s mobile world, the volume of connected devices and data is growing at a rapid pace. As more and more “things” become part of the Internet (refrigerators, pacemakers, cows?), the importance of scalable, reliable and efficient messaging becomes paramount. In this talk we will dive into MQTT: a lightweight, open standard publish/subscribe protocol for rapid messaging between “things”.
MQTT is simple to understand, yet robust enough to support interactions between millions of devices and users. MQTT is being used in connected car applications, mobile banking, Facebook Messenger, and many things in between. In this talk you will learn all about the protocol (in 10 minutes!) and see some of its applications: live-tracking, gaming, and more. We’ll walk through designing an MQTT-based API for a ride-share mobile application, and discuss how MQTT and REST APIs can complement each other.

MQTT with Java - a protocol for IoT and M2M communicationChristian Götz
Our digital world is growing rapidly and we have more devices connected to the internet than ever. On top of that each second 80 new devices are added, which introduces new challenges to communication between these devices. MQTT is a lightweight and scalable protocol that shifts the request/response paradigm of the web as it is today to an event-driven publish and subscribe architecture, which is a perfect fit for Internet of Things and M2M use cases. This talk answers the following three questions: Why do we need a paradigm shift, HTTP has been proven to be a good fit for the web? What is MQTT and how does it help to overcome the challenges we have today? How can everybody build their own MQTT application with the implementation that are available for Java developers ? In the last part we will dive into Eclipse Paho and the FuseSource client library and round up the talk with an live demonstration.
Presentation from the Virtual IoT User Group.
MQTT has been established amongst the most popular IoT protocols for Device-To-Cloud-Communication.
The new MQTT 5 standard, which has been released in early 2018, comes with a number of new features and improvements, making the lightweight protocol more versatile than ever. The technical committee at OASIS worked hard to develop new functionality and improvements for the protocol that were in high demand, without changing MQTT in its fundamental core.
How can those features be applied in real projects? And how backward compatible is the new version? Is it time to upgrade yet? We’ll discuss all these questions and Open Source implementations in this session.

Internet of Things requires communication to devices that are either actuators or sensors. Each actuator and sensor has an identity. Each actuator and sensor may be either directly connected to the world wide web or indirectly connected via a type of gateway.
Communication to these devices needs to be reliable. Therefore each device may implement their most suitable communication protocol.

How do Things talk? IoT Application Protocols 101Christian Götz
Analysts predict that in 2020 50 billion devices are connected to the internet. Together with the fact that more and more of these "things" are connected over the cellular network, new challenges are introduced to the communication of Internet of Things (IoT) and machine-to-machine (M2M) scenarios. There are a lot of protocols which claim to be ideal for these use cases, for example MQTT and COAP. In this talk you will get an overview of commonly used protocols and their underlying architectural styles. We will also look at advantages/disadvantages, use cases and the eco-system around them for Java developers.

MQTT - Communication in the Internet of ThingsChristian Götz
Das Internet der Dinge (IoT) und Maschine-zu-Maschine Kommunikation (M2M) ist momentan in aller Munde. Studien zeigen das es bis 2020 50 Milliarden Geräte sein werden, die über das Internet miteinander kommunizieren und jede Sekunde kommen 80 neue Geräte hinzu. Momentan dominierende Protokolle wie HTTP/REST sind nur bedingt geeignet, um die Anforderungen abzudecken. Herausforderungen sind zum Beispiel das Senden von Nachrichten von einem Gerät zu vielen, Skalierung der Anzahl an Geräte, Push Notifications und Sicherstellung der korrekten Übermittlung. Das Publish/Subscribe-Protokoll MQTT erfüllt diese Anforderungen und wurde für mobile Geräte entwickelt. Es wird beispielsweise von Facebook für den Messenger eingesetzt. Dieser Vortrag gibt eine Einführung in MQTT sowie die Implementierung Eclipse Paho und zeigt anhand von Beispielquellcode und einer Livedemo, welche Probleme man damit lösen kann. - See more at: http://www.developer-week.de/History/2014/Programm/Veranstaltung/(event)/14178#sthash.ioXw2aoi.dpuf

This paper has presented an evaluation of the two widely accepted and emerging messaging protocols for IoT systems: MQTT, and CoAP. MQTT and CoAP are rapidly emerging as leading lightweight messaging protocols for the booming IoT market. Each protocol offers unique benefits, and each poses challenges and tradeoffs. Both protocols are being implemented for mesh-networking applications, in which lightweight end nodes are a necessary aspect of almost every network, and for gateway bridging logic to allow inter-standard communication.
Presenter - Boris Cherkasskiy

The Internet of Things (IoT) has recently gained massive traction. IoT challenges enterprises, small companies, and developers with new problems to solve. While HTTP is
the de-facto protocol for the human web, communication between machines at scale requires a paradigm shift— steering away from request/response and leading towards publish/subscribe. This is where the ultra-lightweight, massively scalable, and easy-to-implement protocol MQTT enters the picture.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

53. MQTT Broker design
• 1 Cowboy process per MQTT or Websocket client
– Receives, sends and handles MQTT protocol frames using
bit-syntax
• 1 gen_server/proces per MQTT Subscriber
– managing MQTT client session
– may survive TCP socket disconnects (according to QoS)
– If client disconnected - queue messages (according to QoS)
• 1 gen_server/process + 1 ETS table per Topic
– manages list of subscribers per topic
– broadcast messages to subscriber processes
54. MQTT Broker design (cont.)
• Subscribers Manager gen_server
– Manages table of subscribers
– Creating new subscriber
– Sending one-to-one messages
• Topics Manager gen_server
– Manages table of topics
– Publish to topic (i.e. broadcast to all topic subsribers)
55. Scaling - Networking
• Tuning Linux TCP Stack – C1M (no C10M) Problem
• SYN flood – SYN cookies
– accumulation of half-open sockets
– being behind load balancer solves this
• Broadcast T-put problem
– Sending pings alone to millions of clients requires a lot of
bandwidth
• Do SSL termination on Load Balancer
• Poor man QoS:
– Separate ports for different protocols
56. Scaling – Erlang/OTP
• Sending messages as binaries
– so it will be 0-copy
– Especially useful for broadcast
• Broadcasting messages at low priority
– so it will not interfere with accepting new clients
• Writing our own broadcast timer code
– since built-in timers do not scale to millions of
processes
• Tricks to fast spawn of new gen_servers
– i.e. spawn gen_server per new subscriber or topic
57. Scaling – Erlang/OTP (cont.)
• Moving data flow from Erlang built-in
Distribution to ØMQ
• Erlang built-in distribution still used for
control-flow and cluster management
