ArangoDB Agency: A New Resilient, Transactional K/V Store - Max Neunhöffer, ArangoDB
For ArangoDB 3.0 we have implemented the Raft consensus protocol in ArangoDB, thereby creating a high-performance resilient K/V store “Agency” based on Raft’s replicated log. This makes it possible to use ArangoDB instead of Zookeeper, Consul or etcd to create resilient distributed applications. Mesos and thus DC/OS are the ideal ecosystem to develop and run distributed applications, and all such applications need fault tolerant management and synchronization between the various tasks.
Features and their benefits:

- transactions involving multiple keys: simpler application logic
- complex redis-like data manipulations: less roundtrips, higher performance
- powerful preconditions for write transactions: less roundtrips, higher performance
- JSON-based HTTP/REST API: accessible from nearly all languages
- subscription to HTTP callbacks: fast reaction on changes
- user-defined supervision tasks JavaScript running in leader: easier implementation of resilience logic

As known from ArangoDB, deployment on Mesos can be done with a single click or command. By the beginning of the conference, we will have tortured ArangoDB Agency with Jepsen tests and I will announce the results in the talk, whatever they are.

Conveyor: Enabling Low-friction Continuous Deployment via Workflows and Containers with Marathon and Apache Mesos - Jonathan Pliske & Tristan Blease, Groupon
Technology organizations are complex environments that bind deeply technical tools and infrastructure with strong cultural threads. Software like Mesos and Docker offer compelling stories around scalability, fault tolerance, and deterministic environments. Nonetheless, many challenges emerge as one attempts to weave these components into an existing engineering culture.

A successful transition to a service-oriented architecture has left Groupon with numerous services deployed to a variety of hardware, physical and virtual, via a diverse set of tools. Along the way the organization has picked up an array of operational readiness requirements and deploy controls. All of these help to maintain stability and performance but come at a cost: ease of deployment.

Conveyor aims to maintain and improve Groupon’s high bar for production software quality, while streamlining the process of getting code into production. Powerful tools like Apache Mesos, Marathon, and Docker form the foundation of this approach. This talk covers how Conveyor uses these tools together and the various technical and cultural hurdles encountered in the process of rolling out this infrastructure within the enterprise.

Automated Testing Laboratory for Embedded Linux Distributions - Paweł Wieczorek, Samsung Electronics
Shipping quality software always involves in-depth testing. In order to minimize time spent on repetitive actions, this task should be fully automated. Unfortunately this creates many problems which have to be solved to ensure stability of the whole process. During this talk Paweł will discuss key problems faced while building automatic testing infrastructure for Tizen operating system images. He will also present how Tizen release team dealt with such an uneasy task. Both hardware and software presented in this talk is open (https://git.tizen.org/cgit/tools/testlab/sd-mux.git and https://git.tizen.org/cgit/tools/testlab/major.git) and can be easily used to build embedded software testing lab.
