Skydive With oVirt

Skydive network is an open source real-time network topology and protocols analyzer providing a comprehensive way of understanding what is happening in your network infrastructure. The common use cases will be, troubleshooting, monitoring, SDN integration and much more. It has features such as:

  • Topology capturing - Captures network topology, interface, bridge and more
  • Flow capture - Distributed probe, L2-L4 classifier, GRE, VXLAN, GENEVE, MPLS/GRE, MPLS/UDP tunnelling support
  • Extendable - Support for external SDN Controllers or container based infrastructure, OpenStack. Supports extensions through API

Benefit to oVirt users

Skydive allows oVirt administrators to see the network configuration and topology of their oVirt cluster. Administrators can capture traffic from VM1 to VM2 or monitor the traffic between VMs or hosts. Skydive can generate traffic between 2 running VMs on different hosts and then analyze. Administrators can create alerts in Skydive UI to notify when traffic is disconnected or down.

Installation steps

  1. git clone https://github.com/skydive-project/skydive.git

  2. Create inventory file

Network Break 195: Google Goes For Hybrid Cloud; Gigamon Buys Security Startup

Take a Network Break! Google targets hybrid cloud with Managed Itsio and GKE On Prem, and then goes after the edge with a new machine learning-friendly ASIC called Edge TPU.

The Chrome browser gets serious about TLS, Qualcomm walks away from its NXP bid, Gigamon acquires Icebrg, and Atlassian agrees to sell HipChat to Slack.

Juniper and Intel announces their second-quarter earnings, and Infinera spends $430 million to buy Coriant.

SSDs poised to get a lot cheaper

If you are SSD shopping for your servers, you might want to wait a little because a market research firm that follows this sector said conditions are ripe for price drops in the coming months.DRAMeXchange, a division of market research firm TrendForce, forecasts that the average selling prices (ASP) of NAND Flash will drop by around 10 percent quarter over quarter respectively in the third and fourth quarters of 2018.Usually Q3 is the time of peak demand as OEMs ramp up manufacturing for the Christmas holiday, but the growth of the end-market demand has been weaker than anticipated. At the same time, the supply of 3D-NAND Flash continues to expand.To read this article in full, please click here

Docker SF Chapter Meetup: BuildKit and Container Orchestration

Last week, we had a great turnout for the Docker San Francisco chapter event at HQ! The meetup was focused on two of the most popular talks from DockerCon on BuildKit and container orchestration with Kubernetes and Docker Swarm. The purpose was to give people who couldn’t attend these talks a chance to hear to hear them live,  provide the opportunity to ask the speakers questions and network with other members of the container ecosystem.

‘Introduction to BuildKit: the Next Generation Builder Component’

Watch Tibor Vass’ Presentation

First, we had Tibor Vass, a software engineer on the Engine Team at Docker and maintainer of the Docker project since 2014, take the podium with his talk ‘Introduction to BuildKit: the Next Generation Builder Component’. In this talk, Tibor went into detail about the latest developments around the builder component of the Docker Platform including BuildKit, a toolkit that builds on containerd to provide next-generation capabilities for building software with the help of containers. Watch his talk to learn about the architecture and design choices of BuildKit’s frontend model, how to use BuildKit directly, and how to leverage its features in Docker. There were a number of great questions from particularly engaged community members!

IDG Contributor Network: A primer on closed-loop automation

Recently, I was reading a blog post by Ivan Pepelnjak on intent-based networking. He discusses that the definition of intent is "a usually clearly formulated or planned intention" and the word “intention” is defined as ’what one intends to do or bring about." I started to ponder over his submission that the definition is confusing as there are many variations.To guide my understanding, I decided to delve deeper into the building blocks of intent-based networking, which led me to a variety of closed-loop automation solutions. After extensive research, my view is that closed-loop automation is a prerequisite for intent-based networking. Keeping in mind the current requirements, it’s a solution that the businesses can deploy. To read this article in full, please click here

Samsung could upset the AI and HPC markets with GPU entry

South Korea’s IT behemoth Samsung is working on a graphics processor unit (GPU) and has hired a major figure from Nvidia to help get the job done, according to a report from a graphics analyst.Jon Peddie Research reports that Samsung has hired Dr. Chien-Ping Lu, a former Nvidia executive who oversaw development of discrete and integrated GPUs used in Apple MacBooks as well as integrated processors before the advent of GPUs in CPUs.Now, many mobile CPUs have integrated GPUs, or the phone itself comes with its own GPU. Qualcomm has its own line called Adreno. But Peddie doesn’t think Samsung hired a heavy hitter like Lu to make mobile phone chips.To read this article in full, please click here
