Cloudflare recognized as a ‘Leader’ in The Forrester New Wave for Edge Development Platforms
Forrester’s New Wave for Edge Development Platforms has just been announced. We’re thrilled that they have named Cloudflare a leader (you can download a complimentary copy of the report here).
Since the very beginning, Cloudflare has sought to help developers building on the web, and since the introduction of Workers in 2017, Cloudflare has enabled developers to deploy their applications to the edge itself.
According to the report by Forrester Vice President, Principal Analyst, Jeffrey Hammond, Cloudflare “offers strong compute, data services and web development capabilities. Alongside Workers, Workers KV adds edge data storage. Pages, Stream and Images provide higher level platform services for modern web workloads. Cloudflare has an intuitive developer experience, fast, global deployment of updated code, and minimal cold start times.”
Reimagining development for the modern web
Building on the web has come a long way. The idea that one might have to buy a physical machine in order to build a website seems incomprehensible now. The cloud has played a major role in making it easier for developers to get started. However, since the advent of the cloud, things have stalled — and innovation has become more incremental. That means that while developers Continue reading
Custom Headers for Cloudflare Pages
Until today, Cloudflare Workers has been a great solution to setting headers, but we wanted to create an even smoother developer experience. Today, we're excited to announce that Pages now natively supports custom headers on your projects! Simply create a _headers file in the build directory of your project and within it, define the rules you want to apply.
/developer-docs/*
X-Hiring: Looking for a job? We're hiring engineers
(https://www.cloudflare.com/careers/jobs)What can you set with custom headers?
Being able to set custom headers is useful for a variety of reasons — let’s explore some of your most popular use cases.
Search Engine Optimization (SEO)
When you create a Pages project, a pages.dev deployment is created for your project which enables you to get started immediately and easily preview changes as you iterate. However, we realize this poses an issue — publishing multiple copies of your website can harm your rankings in search engine results. One way to solve this is by disabling indexing on all pages.dev subdomains, but we see many using their pages.dev subdomain as their primary domain. With today’s announcement you can attach headers such as X-Robots-Tag to hint to Google and other search Continue reading
EVPN/VXLAN Complexity
We have school holidays this week, so I’m reposting wonderful comments that would otherwise be lost somewhere in the page margins. Today: Minh Ha on complexity of emulating layer-2 networks with VXLAN and EVPN.
Dmytro Shypovalov is a master networker who has a sophisticated grasp of some of the most advanced topics in networking. He doesn’t write often, but when he does, he writes exceptional content, both deep and broad. Have to say I agree with him 300% on “If an L2 network doesn’t scale, design a proper L3 network. But if people want to step on rakes, why discourage them.”
vmWare vRealize Automation (with embedded vRO) – Full Example of Custom Resources for Executing Ansible Playbooks from Blueprints
This articles exists because I spend a lot of time in the last year inside vmware vRealize Automation (vRA) that includes an embedded vRealize Orchestrator (vRO) on a undisclosed project. And the main take-away is that the documentation in certain aspects that are on the edge of new features of vRA/vRO are, to put it mildly “documented in a very chaotic way”. Additionally, what worked in vRA 8.0 – 8.2 suddenly stopped working in 8.3 and 8.4 when upgraded. So this product is not yet as stable as I would like and for this article it means that it will probably be completely outdated in a year or so. Nevertheless I wanted to put together a simple example that is working end-to-end and providing practical jump of point for building more.
And I have decided that bridging vRA/vRO with traditional Ansible playbook is a good idea for an example. Because it combines the vRAs great Infrastructure As A Code (IaaS) capabilities of using blueprints with a more infrastructure focused automation of Ansible. We will be building an abstract object on a blueprint (these types of objects are called “custom resource” because you are defining what they Continue reading

Interactions Between BFD and Graceful Restart
We have school holidays this week, so I’m reposting wonderful comments that would otherwise be lost somewhere in the page margins. Today: Dmitry Perets on the interactions between BFD and GR.
Well, assuming that the C-bit is set honestly (will be funny if not) and assuming that the Helper is using this bit correctly (and I think it’s pretty well defined what “correctly” means - see section 4.3 in RFC 5882), the answer is pretty clear.
The Three Stages of Monitoring on the Road to Observability
Getting to an advanced level of observability requires a monitoring evolution from reactive to proactive, and, finally, prescriptive monitoring.VMware Tanzu Service Mesh Named a Leader in GigaOm Radar Report on Service Mesh
GigaOm placed VMware Tanzu Service Mesh (TSM) in the leader ring of its 2021 GigaOm Radar Report for Evaluating Service Mesh, cementing VMware’s status as the open-source choice for connecting and securing modern applications across single and multi-cloud environments.
As enterprises continue to split applications into microservices that can be spun up or down as needed, service meshes give DevOps the ability to seamlessly and simply orchestrate connectivity and security services across multi-cloud environments, automatically and at scale. This common abstraction layer for application services enables true app resiliency, observability, and security across single and multi-cloud environments — a critical superpower for organizations focused on delivering powerful and consistent experiences.
VMware continues to lead
Citing Tanzu Service Mesh’s open-source architecture, dominance in the enterprise market, innovative road map, and focus on improving security, the authors of the report feel that Tanzu Service Mesh gives enterprises the best chance of gaining that all-important visibility and control with modern applications.
The key to this, of course, is Tanzu Service Mesh’s ability to seamlessly abstract the application layer from the infrastructure layer through Global Namespace (GNS). By onboarding applications to a Global Namespace, developers, operations, and security gain consistent policy controls and operational Continue reading

Sudan woke up without Internet
Today, October 25, following political turmoil, Sudan woke up without Internet access.
In our June blog, we talked about Sudan when the country decided to shut down the Internet to prevent cheating in exams.
Now, the disruption seems to be for other reasons. AP is reporting that "military forces ... detained at least five senior Sudanese government figures.". This afternoon (UTC) several media outlets confirmed that Sudan's military dissolved the transitional government in a coup that shut down mobile phone networks and Internet access.
Cloudflare Radar allows anyone to track Internet traffic patterns around the world. The dedicated page for Sudan clearly shows that this Monday, when the country was waking up, the Internet traffic went down and continued that trend through the afternoon (16:00 local time, 14:00 UTC).
We dug in a little more on the HTTP traffic data. It usually starts increasing after 06:00 local time (04:00 UTC). But this Monday morning, traffic was flat, and the trend continued in the afternoon (there were no signs of the Internet coming back at 18:00 local time).
When comparing today with the last seven days' pattern, we see that today's drop is abrupt and unusual.
We can see Continue reading
