Last Wednesday was Docker’s 50th meetup in San Francisco! There was an awesome turnout from the local Docker community to see Docker’s own Nishant Totla and Dongluo Chen and their talk on Swarm Mode.
Nishant and Dongluo gave a talk entitled ‘Using Docker Swarm Mode and healthchecks to Deploy Applications Without Loss’ where they demonstrated how to do service upgrades without impacting your application.
They explained that Docker swarm mode enables users to manage their applications with service primitives and the healthcheck feature provides health indications for a container. Coming up in the Docker 1.13 release, Docker Swarm can connect healthcheck results with load balancers to implement no-loss service upgrade. Check out the talk including Nishant’s demo in the video below.

In many ways, enterprises and hyperscalers have it easy. Very quickly in the wake of its announcement more than two decades ago, the Java programming language, a kind of virtualized C++, became the de facto standard for coding enterprise applications that run the business. And a slew of innovative storage and data analytics applications that have transformed computing were created by hyperscalers in Java and often open sourced so enterprises could use them.
The HPC community – and it is probably more accurate to say the many HPC communities – has it a bit tougher because they use a variety …
Chasing The Dream Of Code HPC Once, Run Anywhere was written by Timothy Prickett Morgan at The Next Platform.
Launch for Nuage's different SD-WAN is set for early 2017.
Here's a quick recap of how the public companies that we cover performed in the third quarter of 2016.
It’s the MANO open source group’s first code release.
The combined company could be an SD-WAN powerhouse.
Why isn’t inbound load balancing working the way I expect? Why are users having a hard time reaching my web site? What is that strange advertisement I see in my local routing table, and where does it lead? The Default Free Zone (DFZ), the land where there is no default route from the edge of the Internet to the core, can seem like an intimidating place to work. There are, however, a number of tools that can help you discover what is going on with your routes, where routes are coming from, and other information. This short series of posts will provide an overview of these tools, and some use cases along the way to help you understand how and where to use them.
Note: throughout this series, I’m going to be using the LinkedIn AS number and routes, as well as the AS numbers of other public companies for illustration. I’m deviating from my normal practice of using addresses and AS numbers reserved for documentation in order to make it possible for readers to perform the same actions and get something like the same results. Do not use these addresses or AS numbers in your network!
Let’s start by Continue reading
