Startup Rips The Switch Out Of High-Performance Networks

The rapid movement of data to the cloud, the sharp rise in the amount of east-west traffic and the broadening adoption of modern applications like artificial intelligence (AI) and machine learning are putting stress on traditional networking infrastructures that were designed for a different era and are struggling to meet the demands for better performance, more bandwidth and less latency. …

Label standard and best practices for Kubernetes security

In this blog post, I will be talking about label standard and best practices for Kubernetes security. This is a common area where I see organizations struggle to define the set of labels required to meet their security requirements. My advice is to always start with a hierarchical security design that is capable of achieving your enterprise security and compliance requirements, then define your label standard in alignment with your design. This is not meant to be a comprehensive guide for all your label requirements, but rather a framework that guides you through developing your own label standard to meet your specific security requirements.

Kubernetes labels for network policies

Labels are key/value pairs that are attached to Kubernetes objects to identify attributes that are intuitive for users and that are required for specific purposes, such as inventory reporting or the enforcement of an intent.

Label classification

Kubernetes network policies represent the intent of enforcing security controls to pods using labels to match intended endpoints. Label prefixes can be used to identify label classification. The following short-list is a high-level classification of endpoints required for developing a Kubernetes network policies design:

• Multi-tenancy
• Application microsegmentation
• External endpoints
• Host endpoints

AnsibleFest 2021 – What it means for Partners

As the weather turns to Fall, the seasons seem to parallel that of the technology cycles. Over the past couple of decades, we have seen various transformations within the high-tech area:

• From mainframe to distributed computing to hybrid cloud and now edge
• From databases to data warehouse to advanced analytics and machine learning
• From the challenges of storing a gigabyte of data, now grown to storing zetabytes+ of data per day.

All of this has moved businesses forward, driving great innovation. When it comes to infrastructure, nothing is more impactful than a core architectural update that fundamentally changes the way enterprises drive their business.  Distributed computing, distributed architectures like cloud, hybrid cloud and edge computing reinforce this  premise in the era of hybrid cloud computing.

The recent announcement of Red Hat Ansible Automation Platform 2 aligns to this blossoming hybrid cloud model, where automation meets the modern hybrid cloud environment.  This represents a great opportunity for our Red Hat Ansible Partner Ecosystem.

How we build software at Cloudflare

Cloudflare provides a broad range of products — ranging from security, to performance and serverless compute — which are used by millions of Internet properties worldwide. Often, these products are built by multiple teams in close collaboration and delivering them can be a complex task. So ever wondered how we do so consistently and safely at scale?

Software delivery consists of all the activities to get working software into the hands of customers. It’s usual to talk about software delivery with reference to a model, or framework. These provide the scaffolding for most modern software delivery models, although in order to minimise operational friction it’s usual for a company to tailor their approach to suit their business context and culture.

For example, a company that designs the autopilot systems for passenger aircraft will require very strict tolerances, as a failure could cost hundreds of lives. They would want a different process to a cutting edge tech startup, who may value time to market over system uptime or stability.

Before outlining the approach we use at Cloudflare it’s worth quickly running through a couple of commonly used delivery models.

The Waterfall Approach

Waterfall has its foundations (pun intended) in construction and Continue reading

Prossimo: Making the Internet Memory Safe

The Let’s Encrypt certificate authority, but it has also turned its hand to fixing memory problems. It sponsors, via Google, so Rust in Linux in no small part to fix its built-in C memory problems. And, it also has a whole department, Rustls, a safer memory-safe code. Memory-safe programs are written in languages that avoid the usual use after free problems. C, C++, and Assembly, for all their speed, make it all too easy to make these kinds of mistakes. Languages such as Rust, Go, and C#, however, Continue reading

Arista’s Evolution to Data-Driven Networking

Arista’s EOS (Extensible Operating System) has been nurtured over the past decade, taking the best principles of extensible, open and scalable networks. While SDN evangelists insisted that the right way to build networks started with the decoupling of hardware and software in the network, manipulated by a centralized, shared controller, many companies failed to provide the core customer requisite in a clean software architecture and implementation coupled with key technical differentiation. This has been the essence of Arista EOS.

Collect hashes from remote computers

I was recently asked to create a script that should calculate the hash values of all files on remote computers. The collection must be done in parallel on all computers.  My choice fell on Bash because it allows to quickly collect hashes using a combination of SSH, sshpass, find and hash (coreutils package). The collect_hashes.sh script […]

Where Would You Need DNS Anycast?

One of the publicly observable artifacts of the October 2021 Facebook outage was an intricate interaction between BGP routing and their DNS servers needed to support optimal anycast configuration. Not surprisingly, it was all networking engineers’ fault according to some opinions¹

There’s no need for anycast²/BGP advertisement for DNS servers. DNS is already highly available by design. Only network people never understand that, which leads to overengineering.

It’s not that hard to find a counter-argument³: while it looks like there are only 13 root name servers⁴, each one of them is a large set of instances advertising the same IP prefix⁵ to the Internet.

Searching through compressed files on Linux

There are quite a few ways to search through compressed text files on Linux systems without having to uncompress them first. Depending on the format of the files, you can choose to view entire files, extract specific text, navigate through file contents searching for content of interest, and sometimes even edit content. IFirst, to show you how this works, I compressed the words file on one of my Linux systems (/usr/share/dict/words) using these commands:$ cp /usr/share/dict/words . $ 7z a words.7z words $ bzip2 -k words $ gzip -k words $ xz -k words $ zip words.zip words How to use the grep command on Linux   The -k options used with the bzip2, gzip, and xz commands kept these commands from removing the original file, which they would by default. The resultant files then looked like this:To read this article in full, please click here
