Docker is Headed to Gartner Catalyst 2017

The Docker team will be in sunny San Diego, CA, August 21-23 for Gartner Catalyst. Come by and visit us in Booth #508 to meet with our Docker Enterprise Edition (EE) experts, see a demo of Docker EE, and ask us any questions you may have before and after any of the Gartner sessions on Docker and containers. Better yet, schedule a meeting with us and we’ll not only answer all your questions, you will also get a special gift.

This year’s Catalyst event includes an entire topic dedicated to Docker and containers, which you can find by looking for the topic “Docker & Containers” in the schedule builder. If you are still trying to separate all the fact from fiction about Docker and want a specific recommendation, there is a great Tech Demo session by Gartner analyst Richard Watson we think you might like titled Seven Docker & Container Myths We Need To Bust. 

We hope you will join us at Gartner Catalyst to get the latest research on the next big trends for IT, but if you are not in San Diego, we hope to see you at one of these other upcoming events:

Feedback: Network Automation 101

Some networking practitioners start their network automation journey with the Python or Ansible dilemma. Engineers and architects usually want to understand the bigger picture first, and figure out the potential showstoppers and roadblocks. One of them left this feedback on the Network Automation 101 webinar:

A must-have overview of fundamental Network Automation concepts. I wouldn't face an automation project without understanding these concepts first.

BGP : iBGP fully meshed solution : Confederations

Today I am going to talk about the one of the BGP article named as BGP Confederations. Now question is why we are using the BGP Confederations. If you guys ever configured the iBGP protocol you need to configure full meshed scenario in iBGP as per the rule of the policy.

With the full meshed network you will have to maintain all the links from all the routers to each other in the internal BGP network. So let us suppose you have 10 routers in your network and you want to configure iBGP network between them, so how many links you required to maintain the fully meshed network here. Well you need to have the 45 links between these 10 routers to establish the iBGP links between all of them.

You ever think that this may be of higher cost and ever router needs to have the information of the other routers in the network. Well to sort out iBGP full meshed network scenario we have two methods and these methods are Confederations and Route Reflectors.

In this article I am going to take the first method and the name is Confederations. In which I will explain how Confederations work and what are the basic Continue reading

Jinja2 For Network Engineers

Jinja2 is a templating language built in python and loosely based on the Django templating language. Jinja2 is used in many projects as a templating engine with some notable examples: Ansible, Salt and Flask. Jinja2 aims to implement some of the most common features of python right into...

5 host network configurations for MLAG

Host network configurations for MultiChassis Link Aggregation (MLAG, also referred to as dual-attach or ‘high availability’) can vary from host OS to host OS, even amongst Linux distributions. The most recommended and robust method is to use Link Aggregation Control Protocol (LACP), which is supported on most host operating systems natively. Host bonds or bonding refers to a variety of bonding methods, but for the purpose of this article it will refer to LACP bonds. The terms etherchannel, link aggregation group (LAG), NIC teaming, port-channel and bond can be used interchangeably to refer to LACP depending on the vendor’s nomenclature. For the sake of simplicity, we will just call it bonds or bonding. This post will take your through the steps for host network configurations for MLAG across five different operating systems.

Why LACP? LACP is a IEEE standard that has been available since 2000 known as 802.3ad. This makes a highly interoperable standards approach to bonding that can work across many network vendors and host operating systems. LACP is superior to static configuration (also referred to bond-mode ON) because there is a control protocol keeping the bond active. This means failover is predictable and automatic. This is also Continue reading

Worth Reading: Hacking through the random number generator

Late Last Autumn, a Russian mathematician and programmer named Alex decided he’d had enough of running his eight-year-old business. Though his St. Petersburg firm was thriving, he’d grown weary of dealing with payroll, hiring, and management headaches. He pined for the days when he could devote himself solely to tinkering with code, his primary passion. The time had come for an exit strategy. —Brendon Koerner @ Wired

How To Do Stateless Compute, Clustered Storage Like A Hyperscaler

There are so many companies that claim that their storage systems are inspired by those that have been created by the hyperscalers – particularly Google and Facebook – that it is hard to keep track of them all.

But if we had to guess, and we do because the search engine giant has never revealed the nitty gritty on the hardware architecture and software stack underpinning its storage, we would venture that the foundation of the current Google File System and its Colossus successor looks a lot like what storage upstart Datrium has finally, after many years of development, brought …

Data center provider Equinix bets big on fuel cells

Data center provider Equinix is making a big bet on fuel cells to power its facilities by installing natural gas-powered fuel cells at 12 of its U.S. data centers. It’s part of a push for the firm to be 100% reliant on renewable fuels, and it could set an example for other data centers in power management.Equinix uses fuel cells developed by Bloom Energy, a leader in the data center energy market that has been profiled by 60 Minutes and whose giant “batteries” are installed at data centers run by eBay, Apple, NTT, CenturyLink and Verizon.To read this article in full or to leave a comment, please click here
