3rd Docker Switzerland User Group Meetup

IMG_0398

We organised the 3rd Docker Switzerland User Group meetup yesterday, 24th of March 2015. The event was hosted at the premises of Rackspace at Technopark in Zurich and was sponsored by VSHN. The event, with about 40 attendees, started at 1800 hours with the opening talk of our own Florian Dudouet who is responsible for organising the Docker Switzerland user group meets, followed by a talk from Sebastien Goasguen from Citrix, on the Docker Machine, Compose and Swarm.

The second and final talk was from our own Martin Bloechlinger, who presented and gave a demo on Migrating an Application into the Cloud with Docker and CoreOS.

A big thanks to VSHN for the delicious pizzas, and the beer from the ICCLab, no one left unsatisfied! Many thanks to Rackspace for providing the space, and giving a chance to see the cool cow (only who helped clearing up and the insiders will know of this)!

It was a fun meetup and we look forward to repeating that again in a couple of months time. Bis später!

Cloud Incident Management Survey

We are conducting research in order to find out more about how companies handle Cloud Incident Management in their infrastructure (ICT / Cloud).

To this end, we would be grateful if you could fill in the following survey so we could get more information about how your company does it, what tools you use (if any) and other opinions you have on the matter. Filling in the survey will only take a few minutes of your precious time.

When there will be enough data to get good statistics, we will disseminate anonymized results of the survey.

ICCLab @ 10th KuVS Expert-Talks NGSDP

Last Monday, the 16. March 2015 the 10th expert-talks on Next Generation Service Delivery Plattforms (NGSDP) was held at the Fraunhofer FOKUS Institute in Berlin.

The event was about “Virtualization Impacts on Service Delivery Infrastructures – SDN, SNF and Clouds”. There were a wide range of intersting talks covering topics like NFV Orcherstration, Optimization Models for Virtual Mobile Core Network Functions Embedding, Prototyping New Concepts Beyond 4G – The Open5GCore and many more. After every talk there was a short round of questions and a longer pannel with engaging discussions.

The ICCLab was there presenting on the topic of Cloud-Native Application Design, explaining the necessary characteristics of a Cloud-Native Application and giving some hints on the designing process.

Software Defined Networking for Clouds

Description

Software Defined Networking (SDN) is a technology that has introduced an important paradigm shift in the networking world. With the OpenFlow protocol as a main technological enabler, the essential goal is to extend the conventional network configuration approach by introducing the concept of network control and programmability.

The advances in the OpenFlow protocol and the strong community involved in the OpenDaylight (ODL) framework has significantly leveraged SDN over the past few years, which booked it a ticket as a de-facto technology in the datacenter network management journey. To follow this initiative, OpenStack has been a pioneer technology that urged to provide a direct SDN support for Neutron. Such approach has introduced new challenges arising from the direct mapping of network traffic between the physical hosts and the virtual tenant networks.

Identifying scenarios that embrace different issues to consider, has a high priority in the current SDN world. With the main focus on SDN-managed datacenter networks, this initiative will provide a technical implementation and know-how on managing cloud-based network resources in a straightforward manner.

Objectives

The “SDN for clouds at the ICCLab” mission involves: establishing use cases, revealing potential issues, analyzing alternative approaches and optimizations in order to achieve efficient networking for classical datacenters, network carriers, Internet Service Providers and Cloud providers. The tasks to achieve this include:

  • Provide on-demand, scalable, commodity deployment to facilitate SDN knowledge transfer to academia and business partners
  • Provide Network as a Service for the tenants
  • Monitor and optimize intra-cloud-traffic
  • Automate changing flows with the SDN-controller
  • Minimize complexity of the network logic
  • Efficient handling of QoS and QoE network parameters
  • Independent network-hardware vendors

Research Challenges

The on-going technology and protocols applied to cloud networking are not optimal in terms of resource usage, reliability, deployment and maintenance. For example, the current implementation of Open Stack Neutron relies on different tunnelling mechanisms in order to provide isolation and multi-tenancy support. From a network application developer point of view, this is inefficient since it injects additional overhead and impedes a transparent application development.

To address the issues in that context, we define the following research tasks:

  • Reconsider the current concepts and state of the art proposals and determine a sophisticated solution towards optimized SDN design for modern cloud architectures
  • Define competitive use cases as direct controllers and evaluators of our SDN solution
  • Provide a high level framework for management of cloud based network resources in a uniform manner

Relevance to current and future markets

Having in-house deployment implies an up and running environment prepared to leverage ideas deployed and tested over commodity-hardware. The ICCLab SDN testbed will essentially facilitate the validation of use cases towards comprehensive solutions. The high-level framework on top of the ODL controller will provide smart virtual datacenter management in OpenStack deployments, and potentially target industry partners among the content delivery network companies, like Akamai for example, IPTV and streaming service providers. We also aim to expand the cooperation by exchanging technical expertise with industry partners involved in the SDN-Cloud field.

The ICCLab is happy to announce the 4th Open Cloud Day on 16th of June in Bern. Like the previous years, the day long event focuses on the goal to foster open clouds and interoperability of clouds, especially taking into account the requirements of public administrations and large as well as small and medium-sized businesses.

Concrete cloud stacks will be discussed during the course of several talks and in the afternoon there will be specific workshops, from enterprises sharing and showing their know-how in latest Cloud technologies. The developments in Gov Clouds will also be discussed.

The event is planned as a full day event (single or double track) with 2-3 training session for specific cloud stacks (hands-on).

Save the date and register soon!

Date: Tuesday, 16th June 2015

Time: 09:00 – 17:00

Venue: University of Bern, UniS, Schanzeneckstrasse 1, Bern.

Reliability Analysis of OpenStack VMs using Python, fabric and R – Part 2: Reliability Measurements

After having completed part 1 of our series about reliability analysis, we now start with our first reliability measurement experiment. According to reliabili theory there are three things we could measure: survival probability, hazard rate and failure rate. The last one is the easiest one in practice. Therefore we design an experiment to measure the failure rate of OpenStack VMs under heavy load.

Failure rates can be constant, ascending or declining over time. In order to measure the general tendency of a failure rate we have to perform a time series analysis. We start up several OpenStack VMs, put them under stress by running a certain task on them and then count how many of the VMs are still alive after a certain amount of time. The stress task is performed several times on the same VMs and the number of machines that are still alive is counted repeatedly in order to get a time series of failure rates.

  2. Our own Sean Murphy and his team (Bruno and Vojtech) from ZHAW on “Making OpenStack more energy efficient”, including an interesting demo introducing the web app AEM – Arcus Energy Monitoring Tool  from Bruno.IMG_0359
  3. Alexander Gabert from Midokura on “OpenStack, Network Virtualization overlays”

Then a 30 mins break for food and drinks

And then again 3 presentations in the 2nd session (20 mins each)

  1. Theodor Basler from Nimble Storage on “Nimble Storage next Generation Adaptive Flash Platform”
