Reader Question: What Networking Blogs Would You Recommend?

A junior networking engineer asked me for a list of recommended entry-level networking blogs. I have no idea (I haven’t been in that position for ages); the best I can do is to share my list of networking-related RSS feeds and the process I’m using to collect interesting blogs:

Infrastructure

• RSS is your friend. Find a decent RSS reader. I’m using Feedly – natively in a web browser and with various front-ends on my tablet and phone (note to Google: we haven’t forgotten you killed Reader because you weren’t making enough money with it).
• If a blog doesn’t have an RSS feed I’m not interested.

Gelsinger Leads Emboldened Intel With Ice Lake Launch

The past several years haven’t been easy on Intel. The world’s top processor maker stumbled on its transition from 14 nanometer to 10 nanometer manufacturing and still finds itself behind rivals like AMD and Arm, which have made the move to 7 nanometer processes and which have line of sight on 5 nanometer. …

Intel releases 3rd-gen Xeon Scalable processor

Intel today launched the third generation of its Xeon Scalable server-processor line with more than three dozen new chips built on its long-overdue 10-nanometer manufacturing process and featuring a host of specialized features for security and AI.The new chips were developed under the codename Ice Lake and were long in coming, due to the delays Intel had getting its manufacturing process down to 10nm. AMD, through its TSMC manufacturing partner, is at 7nm and its Epyc processors are slowly but increasingly taking market share from Intel.Now see "How to manage your power bill while adopting AI" Intel says the Ice Lake series has a 20% improvement in the number of instructions that can be carried out per clock cycle over the prior generation, thanks to the smaller process node letting them cram more transistors into the package.To read this article in full, please click here

How Calico Cloud’s runtime defense mitigates Kubernetes MITM vulnerability CVE-2020-8554

Since the release of CVE-2020-8554 on GitHub this past December, the vulnerability has received widespread attention from industry media and the cloud security community. This man-in-the-middle (MITM) vulnerability affects Kubernetes pods and underlying hosts, and all Kubernetes versions—including future releases—are vulnerable.

Despite this, there is currently no patch for the issue. While Kubernetes did suggest a fix, it only applies to external IPs using an admission webhook controller or an OPA gatekeeper integration, leaving the door open for attackers to exploit other attack vectors (e.g. internet, same VPC cluster, within the cluster). We previously outlined these in this post.

Suggested fixes currently on the market

Looking at the Kubernetes security market, there are currently a few security solutions that attempt to address CVE-2020-8554. Most of these solutions fall into one or two of three categories:

1. Detection (using Kubernetes audit logs)
2. Prevention (using admission webhook controller)
3. Runtime defense (inline defense)

A few of the solutions rely on preventing vulnerable deployments using an OPA gatekeeper integration; these solutions alert users when externalIP (possibly loadBalancerIP) is deployed in their cluster configurations. Most solutions, however, present a dual strategy with a focus on prevention and detection. They use an admission controller for Continue reading

History of Internet 2: Dale Finkelsen

The Internet was originally designed as a research network, but eventually morphed into a primarily commercial system. While “Internet 2” sounds like it might be a replacement for the Internet, it was really started as a way to interconnect high speed computing systems for researchers—a goal the Internet doesn’t really provide any longer. Dale Finkelsen joins Donald Sharp and Russ White for this episode of the History of Networking to discuss the origins of Internet 2.

Intel Fields A 10 Nanometer Server Chip That Competes

At long last, Intel is finally shipping a Xeon SP processor that is based on a 10 nanometer chip manufacturing process and it is finally able to do a better job competing on the technical and economic merits of its Xeon SP processors as architected rather than playing the total system card or the risk card or the discount card to keep its core datacenter compute engine business humming along. …

Getting Started With BGP Global Resource Modules

With the increasing size and complexity of modern enterprise networks, the demand on simplifying the networks management becomes more intense. The introduction of resources modules with Ansible Engine 2.9 provide a path to users to ease the network management, especially across multiple different product vendors.

In the past, we’ve already covered resource modules for OSPF management and for ACLs. However, simplifying network management is not limited to rather local network setups or intra domain routing only. “Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information between autonomous systems (AS) on the internet. The protocol is often classified as a path vector protocol but is sometimes also classed as a distance-vector routing protocol.” It is used in larger network setups, as the NetworkWorld so aptly observes:

BGP has been called the glue of the Internet and the postal service of the internet. One comparison likens BGP to GPS applications on mobile phones.

Managing BGP manually for a network device can be a very difficult and tedious task, and more often this needs to be performed carefully, as the manual process is more prone to human error.

Free Exercise: Build Network Automation Lab

A while ago, someone made a remark on my suggestions that networking engineers should focus on getting fluent with cloud networking and automation:

The running thing is, we can all learn this stuff, but not without having an opportunity.

I tend to forcefully disagree with that assertion. What opportunity do you need to test open-source tools or create a free cloud account? My response was thus correspondingly gruff:

Immersion cooling firm LiquidStack launches as a stand-alone company

Ever since Bitcoin was introduced back in 2009, this cryptocurrency has had the distinction of being something you could mine with your computer—putting your hardware to use helping the blockchain technology Bitcoin is based on record and verify transactions by solving complex math problems.As a reward, you’d get Bitcoins. But it was a very slow process for a single PC, and the necessary component for success was a high-end GPU. One GPU brought to bear on Bitcoin could take years to find one coin, so miners started building massive farms akin to data centers but without enclosures. The result was that Bitcoin farms bought up all the GPUs, causing severe shortages and infuriating gamers.To read this article in full, please click here

Service Meshes in the Cloud Native World

Microservices have taken center stage in the software industry. Transitioning from a monolith to a microservices-based architecture empowers companies to deploy their application more frequently, reliably, independently, and with scale without any hassle. This doesn’t mean everything is green in Microservice architecture; there are some problems that need to be addressed, just like while designing distributed systems. This is where the “Service Mesh” concept is getting pretty popular. We have been thinking about breaking big monolithic applications into smaller applications for quite some time to ease software development and deployment. This chart below, borrowed from Burr Sutter’s talk titled “Burr Sutter at Devoxx The introduction of the service mesh was mainly due to a perfect storm within the IT scene. When developers began developing distributed systems using a multi-language (polyglot) approach, they needed dynamic service discovery. Operations were required to handle the inevitable communication failures smoothly and enforce network policies. Platform teams started adopting container orchestration systems like Envoy.
