Hosts Roopa Prabhu and Pete Lumbis are joined by a special guest to the podcast, Russ White! The group come together virtually to discuss what we should think about when it comes to routing protocols in the datcenter. What are the tradeoffs when using traditional protocols like OSPF or BGP? What about new protocols like RIFT or a hybrid approach with things like BGP-link state? Spoiler alert: it depends.

In today’s fast-paced development world CTOs, dev managers and product managers demand quicker turnarounds for features and defect fixes. “No problem, boss,” you say. “We’ll just use containers.” And you would be right but once you start digging in and looking at ways to get started with containers, well quite frankly, it’s complex.
One of the biggest challenges is getting a toolset installed and setup where you can build images, run containers and duplicate a production kubernetes cluster locally. And then shipping containers to the Cloud, well, that’s a whole ‘nother story.
Docker Desktop and Docker Hub are two of the foundational toolsets to get your images built and shipped to the cloud. In this two-part series, we’ll get Docker Desktop set up and installed, build some images and run them using Docker Compose. Then we’ll take a look at how we can ship those images to the cloud, set up automated builds, and deploy our code into production using Docker Hub.
Docker Desktop is the easiest way to get started with containers on your development machine. The Docker Desktop comes with the Docker Engine, Docker CLI, Docker Compose and Kubernetes. With Docker Desktop there Continue reading
Four people now live and work in my home 24×7; my wife Andi, her mother, my daughter and myself. Many of you now live in similar situations.
Very occasionally, everyone will have network trouble, such as occurred to us this morning. Sometimes it is our “last mile” connection: it is easy to see these failures in our cable modem log. (Often available by looking at the address 192.168.100.1, which seems to be the default address for cable modems.). Occasionally it can be the ISP (in our case, Comcast), either due to some routing failure or DNS failure. These can be harder to diagnose.
Bufferbloat, however, is insidious. It comes and goes, and most users have been “trained” to ignore temporary bad behavior over many years. When you go to diagnose it, you usually stop the operation that is causing it. This blog has recorded our efforts to fix bufferbloat. Now that there are many more people at home at the same time trying to do more demanding applications, this problem is much more common. Other people in your home can inflict the bufferbloat problem on you without you or they understanding what is happening.

We get the architectural nitty-gritty on a multi-cloud migration to Azure and Oracle Cloud on today's Day Two Cloud podcast. Guest Snehal Patel, Network and Cloud Architect for a large corporation, walks us through design and migration details as his company moves applications into two different public clouds.
The post Day Two Cloud 045: Tackling Multi-Cloud Challenges With An Actual Multi-Cloud Consumer appeared first on Packet Pushers.
In this episode we discuss with John Scudder how to drive an idea to a standard via the standards organisation IETF.
John is a IETF veteran and tells us all about workgroups, chairs, drafts and RFCs.

Just a decade ago, public cloud titans Amazon Web Services and Microsoft Azure Cloud, became synonymous with elastic scaling, and software provisioning through APIs. This was a phenomenon that didn’t exist within closed legacy systems.
Private clouds, by contrast, saw the relevance of enterprise customers recreating an infrastructure based on public cloud principles operating at a smaller scale. In an ideal world, both clouds would allow application developers to create and choose where to deploy applications without trade-offs. Arista pioneered technology development in this cloud networking category and today with Covid-19 restrictions driving millions of users to work-from-home, there are tremendous pressures on network access and bandwidth.

One of the hands-on exercises in our Networking in Public Cloud Deployments online course asks the attendees to deploy a full-blown virtual networking solution with a front-end (web) server in a public subnet, and back-end (database) server in a private subnet.
The next (optional) exercise asks them to add IPv6 to the mix for a full-blown dual-stack deployment.
Packet duplication wastes bandwidth and can lead to significant network performance degradation or even outages.
In multicast routing, packets are replicated by the network, so there is always a fundamental risk of duplicate traffic. Special safeguards exist to avoid …
50 years ago when the first Earth Day happened, the networks that would later form the Internet were only beginning.
20 years later, when Earth Day 1990 turned the celebration into a global event, the World-Wide Web existed only as a single website in Switzerland.
Today, the Internet is our lifeline. In a world locked down by coronavirus, the Internet is how we connect. It is how we communicate, collaborate, and create together. It is how we work and how we play. And on this Earth Day 2020, we will use the Internet to celebrate the 50th anniversary.
Each and every day, we are using the Internet to respond to climate change and other environmental issues:
