Navigating Single Cloud, Multi-Cloud, and Hybrid Cloud Environments
Before deciding on a cloud strategy, enterprises must fully understand the possibilities and the limitations that come with single cloud, multi-cloud, and hybrid cloud environments.Repetition Without Repetition
I just finished spending a wonderful week at Cisco Live EMEA and getting to catch up with some of the best people in the industry. I got to chat with trainers like Orhan Ergun and David Bombal and see how they’re continuing to embrace the need for people in the networking community to gain knowledge and training. It also made me think about a concept I recently heard about that turns out to be a perfect analogy to my training philosophy even though it’s almost 70 years old.
Practice Makes Perfect
Repetition without repetition. The idea seems like a tautology at first. How can I repeat something without repeating it. I’m sure that the people in 1967 that picked up the book by Soviet neurophysiologist Nikolai Aleksandrovitsch Bernstein were just as confused. Why should you do things over and over again if not to get good at performing the task or learning the skill?
The key in this research from Bernstein lay in how the practice happens. In this particular case he looked at blacksmiths to see how they used hammers to strike the pieces they were working on. The most accurate of his test subjects didn’t just perform the Continue reading

connect() – why are you so slow?
It is no secret that Cloudflare is encouraging companies to deprecate their use of IPv4 addresses and move to IPv6 addresses. We have a couple articles on the subject from this year:
- Amazon’s $2bn IPv4 tax – and how you can avoid paying it
- Using DNS to estimate worldwide state of IPv6 adoption
And many more in our catalog. To help with this, we spent time this last year investigating and implementing infrastructure to reduce our internal and egress use of IPv4 addresses. We prefer to re-allocate our addresses than to purchase more due to increasing costs. And in this effort we discovered that our cache service is one of our bigger consumers of IPv4 addresses. Before we remove IPv4 addresses for our cache services, we first need to understand how cache works at Cloudflare.
How does cache work at Cloudflare?
Describing the full scope of the architecture is out of scope of this article, however, we can provide a basic outline:
- Internet User makes a request to pull an asset
- Cloudflare infrastructure routes that request to a handler
- Handler machine returns cached asset, or if miss
- Handler machine reaches to origin server (owned by a customer) to pull the Continue reading
IPB144: AWS Adds New Charge for IPv4, Governments Push toward IPv6
A round-up of IP address news to start the new year: Eric Vyncke of the IETF has created an RFC 6724 website that is an excellent time-saving tool for figuring out source destination address selection processes. AWS announces more IPv6 features and support, and adds a new charge for public IPv4 use. State actors, including... Read more »D2C232: Chaos Engineering: Breaking Things on Purpose

Join us at CalicoCon 2024, co-located with KubeCon + CloudNativeCon Europe 2024
We are excited to announce CalicoCon 2024, an in-person learning event for Project Calico, taking place March 19th, 2024 as a co-located event with KubeCon + CloudNativeCon Europe 2024.
As Kubernetes continues to expand its presence in both enterprises and small-to-medium businesses, understanding container networking and security in managed or self-managed Kubernetes environments becomes crucial. Organizations are now presented with choices for dataplanes, such as eBPF, Windows HNS, and Linux IP tables, multi-cloud and Kubernetes distributions as they scale their applications and make them more performance-efficient. Additionally, the process of creating new cloud-native applications or modernizing legacy applications also presents Kubernetes users with a selection of cutting-edge and mature container networking and security technologies.
To make these decisions to leverage their existing investments and future-proofing, users require guidance on developing and implementing scalable network security policies, selecting dataplanes, achieving low latency, optimizing resources, and integrating with bare metal and VM workloads.
What can you expect?
At CalicoCon, we will provide KubeCon Paris 2024 attendees with an opportunity to actively participate in a full-day event where they will:
- Discuss how to incorporate the latest Calico eBPF container networking and security innovations into their applications
- Discover best practices for securing Continue reading
Rethinking the Impossible: How AI Makes Edge Computing Even More Powerful
Edge computing has evolved from its legacy foundations to its modern format where servers are closer to the end user. Now, the addition of AI allows real-time, automated analysis and insights at the edge, providing benefits for a wide variety of industries.Fulfilling the promise of single-vendor SASE through network modernization
As more organizations collectively progress toward adopting a SASE architecture, it has become clear that the traditional SASE market definition (SSE + SD-WAN) is not enough. It forces some teams to work with multiple vendors to address their specific needs, introducing performance and security tradeoffs. More worrisome, it draws focus more to a checklist of services than a vendor’s underlying architecture. Even the most advanced individual security services or traffic on-ramps don’t matter if organizations ultimately send their traffic through a fragmented, flawed network.
Single-vendor SASE is a critical trend to converge disparate security and networking technologies, yet enterprise "any-to-any connectivity" needs true network modernization for SASE to work for all teams. Over the past few years, Cloudflare has launched capabilities to help organizations modernize their networks as they navigate their short- and long-term roadmaps of SASE use cases. We’ve helped simplify SASE implementation, regardless of the team leading the initiative.
Announcing (even more!) flexible on-ramps for single-vendor SASE
Today, we are announcing a series of updates to our SASE platform, Cloudflare One, that further the promise of a single-vendor SASE architecture. Through these new capabilities, Cloudflare makes SASE networking more flexible and accessible for Continue reading

One of the few beauties of most “industry standard CLI” implementations1 is that they’re idempotent: nothing changes (apart from ACLs) if you configure the same stuff a dozen times. Most of these implementations allow you to deconfigure the same stuff multiple times; FRRouting is one of the unfortunate exceptions.
I’m not saying what FRRouting does is wrong. It’s just different and a bit unexpected once you get into the mindset of “Wow, it looks almost like Cisco IOS.”
What Am I Talking About?
Imagine you have a bunch of IP prefixes you want to advertise with BGP. You could use network statements within the router bgp configuration to get that done:

DNS and the DELEG Proposal
The DNS is a large-scale distributed database, where the internal structure of the databaase mirrors the hierarchical nature of the name space itself. In the database the points of delegation from one node to another are de noted by DNS Nameserver records. This structure has served the DNS adequately for many decades, so why change it?DNS and the DELEG Proposal
