Juniper Apstra Freeform Supports New Topologies, Protocols For Data Center Automation–With Caveats
Juniper Apstra has introduced Freeform, a new way to consume Apstra's data center automation platform without being tied to stringent reference architectures. While Freeform expands the network topologies and protocols Apstra can work with, it comes with its own tradeoffs.

Real-time analytics on network flow data with Apache Pinot describes LinkedIn's flow ingestion and analytics pipeline for sFlow and IPFIX exports from network devices. The solution uses Apache Kafka message queues to connect LinkedIn's InFlow flow analyzer with the Apache Pinot datastore to support low latency queries. The article describes the scale of the monitoring system, InFlow receives 50k flows per second from over 100 different network devices on the LinkedIn backbone and edge devices and states InFlow requires storage of tens of TBs of data with a retention of 30 days. The article concludes, Following the successful onboarding of flow data to a real-time table on Pinot, freshness of data improved from 15 mins to 1 minute and query latencies were reduced by as much as 95%.
Using Cloudflare R2 as an apt/yum repository
In this blog post, we’re going to talk about how we use Cloudflare R2 as an apt/yum repository to bring cloudflared (the Cloudflare Tunnel daemon) to your Debian/Ubuntu and CentOS/RHEL systems and how you can do it for your own distributable in a few easy steps!
I work on Cloudflare Tunnel, a product which enables customers to quickly connect their private networks and services through the Cloudflare global network without needing to expose any public IPs or ports through their firewall. Cloudflare Tunnel is managed for users by cloudflared, a tool that runs on the same network as the private services. It proxies traffic for these services via Cloudflare, and users can then access these services securely through the Cloudflare network.
Our connector, cloudflared, was designed to be lightweight and flexible enough to be effectively deployed on a Raspberry Pi, a router, your laptop, or a server running on a data center with applications ranging from IoT control to private networking. Naturally, this means cloudflared comes built for a myriad of operating systems, architectures and package distributions: You could download the appropriate package from our GitHub releases, brew install it or apt/yum install it (https://pkg.cloudflare.

Multi-Cloud: Myths and Reality
I keep hearing numerous variations of the following argument from people believing in the unlimited powers of multi-cloud1 (deploying your workloads in multiple public cloud providers):
We don’t install all our servers in the same DC. But would you trust one Cloud Server Provider with all your applications? That’s why you should use multi-cloud.
I’ve been hearing similar arguments for at least 30 years, including:

Hedge 147: The SRE with Niall Murphy (part 1)
It seems like only yesterday we started talking about the Site Reliability Engineer, and their place in the IT ecosystem. Over the last several years, the role of the SRE has changed—and it’s bound to continue changing. On this episode of the Hedge, Niall Murphy joins Tom Ammon and Russ White to discuss the changing role of the SRE, and what the SRE could be.

Day Two Cloud 163: Is The Tech Market Too Focused On Developers?
Today on the Day Two Cloud podcast we have a frank discussion about tech marketing. Why? Because engineers are a target of marketing, so it's helpful to know how marketing works, what's trying to be communicated, and how it could be better. We also discuss whether the tech industry has over-committed on chasing developers while ignoring operations and sysadmins, why ops and sysadmins shouldn't be ignored, and more. Our guest is Gina Rosenthal, founder of Digital Sunshine Solutions.
