Custom Headers for Cloudflare Pages

Custom Headers for Cloudflare Pages
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.

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

Ansible for AWS: Introduction to Spot Instance Automation

What are Spot Instance and Spot Instance Requests?

A Spot Instance is an instance that uses spare AWS EC2 capacity that is available for less than the On-Demand price. Because Spot Instances provide the ability to request unused EC2 instances at steep discounts, it can lower your Amazon EC2 costs significantly. 

Spot Instances are a cost-effective choice if you can be flexible about when your applications run and whether your applications can be interrupted. For example, Spot Instances are well-suited for data analysis, batch jobs, background processing, and optional tasks.

 

Managing Spot Instances with Ansible

So you want to manage your Spot Instance Requests with Ansible Automation Platform? When it comes to managing AWS resources, the Ansible Amazon AWS Collection includes a variety of Ansible content to help automate the management of AWS instances. Using Ansible to automate applications in AWS greatly increases the chances that your cloud initiative will be a success.  

With the latest addition of new modules to the Ansible Amazon AWS Collection, we have introduced two new modules to help manage Spot Instance Requests efficiently.

The ec2_spot_instance module helps in creating as well as terminating the Spot Instance Requests, while it’s companion module, Continue reading

Graphcore beefs up data center AI offerings

Graphcore, the British semiconductor company that develops accelerators for AI and machine learning, has greatly increased the performance of its massively parallel Intelligence Processing Unit (IPU) servers.Graphcore sells its AI-oriented chips in rack-mounted designs called IPU-PODs. Up until now, the maximum per cabinet has been 64 units (in the IPU-POD64). The newest racks are twice and four times as large: the IPU-POD128 and IPU-POD256.

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.”

Why aren’t optical disks the top choice for archive storage?

Optical media is the longest lasting medium currently in production. It can reliably hold onto your data for 50-100 years without power or cooling, and without the worry of magnetic degradation. Using recordable optical media such as DVD-R is perfectly suitable for long-term archiving because it is write-once, read-many, meaning it is physically immutable—cannot be changed—so the data on it is tamper-proof.[Get regularly scheduled insights by signing up for Network World newsletters.] It seems, then, that optical media might dominate archived storage, but it doesn’t. To explore why, first let’s take a look at the technology.To read this article in full, please click here

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

Cisco upgrades network and collaboration tools for hybrid work

The growing impact of hybrid work is resulting in a reassessment of the IT network infrastructure including the ability to glean analytic details from remote workers and ensure collaboration assets are working properly.Going forward, organizations should expect Cisco products that will help to further lock down networks and support application-monitoring and collaboration environments for hybrid workers, Todd Nightingale, the company’s executive vice president and general manager for enterprise networking cloud told Network World head of his keynote at this week’s Cisco WebexOne 2021 virtual conference.To read this article in full, please click here

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.

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
