Serverless Rust with Cloudflare Workers

Serverless Rust with Cloudflare Workers

The Workers team just announced support for WebAssembly (WASM) within Workers. If you saw my post on Internet Native Apps, you'll know that I believe WebAssembly will play a big part in the apps of the future.

It's exciting times for Rust developers. Cloudflare's Serverless Platform, Cloudflare Workers, allows you to compile your code to WASM, upload to 150+ data centers and invoke those functions just as easily as if they were JavaScript functions. Today I'm going to convert my lipsum generator to use Rust and explore the developer experience (hint: it's already pretty nice).

The Workers teams notes in the documentation:

...WASM is not always the right tool for the job. For lightweight tasks like redirecting a request to a different URL or checking an authorization token, sticking to pure JavaScript is probably both faster and easier than WASM. WASM programs operate in their own separate memory space, which means that it's necessary to copy data in and out of that space in order to operate on it. Code that mostly interacts with external objects without doing any serious "number crunching" likely does not benefit from WASM.

OK, I'm unlikely to gain significant performance improvements on this particular Continue reading

Cognitive Campus – Next Frontier

cognitive-campus-blog

Arista’s focus on disruption, with datacenters and routing, transforming siloed places in the network to seamless Places In the Cloud (PICs) has been well appreciated by our customers. Our cloud networking decade has been achieved by upholding these cloud principles and I believe these trends will influence cognitive campus PICs. Legacy campus networks suffer from a similar complexity of too many layers, boxes, cables, operating systems, proprietary features and network management choices. A change is very much needed and welcome in the 2020 era.

Event-Driven Network Automation in Network Automation Online Course

Event-driven automation (changing network state and/or configuration based on events) is the holy grail of network automation. Imagine being able to change routing policies (or QoS settings, or security rules) based on changes in the network.

We were able to automate simple responses with on-box solutions like Embedded Event Manager (EEM) available on Cisco IOS for years; modern network automation tools allow you to build robust solutions that identify significant events from the noise generated by syslog messages, SNMP traps and recently streaming telemetry, and trigger centralized responses that can change the behavior of the whole network.

BGP and Suboptimal Route Reflection

One of the crucial points in understanding the operation of BGP is the reliance on the AS path to ensure all routes are loop-free. Within a single AS, however, there is no AS path. How, then, can you ensure the path through an AS is loop-free? The original plan was to fully mesh all the BGP speakers in the AS (a full mesh of iBGP speakers)—but building and maintaining a full mesh of iBGP speakers is difficult, so other solutions were quickly designed. The first of these as the BGP Confederation, which allows a set of autonomous systems to look like a single AS from the outside. This solution, however, is also cumbersome, so… the RR was invented.

TL;DR
  • BGP RR’s abstract information in a way that can cause suboptimal routing
  • To resolve this suboptimal routing, additional paths are advertised to RRCs by RRs

 

The basic operation of an RR is fairy simple; as new attribute, the cluster list, is added to a route as is passes from client to server. The cluster list contains as list of the clusters the route has passed through, identified by the identifier of the route reflector that “heads” the cluster. If a Continue reading

This October is the 15th annual National Cybersecurity Awareness Month in the United States, a collaboration between the US government and industry to raise awareness about the part we can all play in staying more secure online. Here at Cloudflare, where our mission is to help build a better internet, we look forward to this month all year.

As part of this month-long education campaign, Cloudflare is participating in D.C CyberWeek this week, the largest cybersecurity festival in the U.S, taking place in Washington, DC. This year’s event is expected to have over 10,000 attendees, more than 100 events, and feature representatives from over 180 agencies, private companies, and service providers. We will join with other leaders in cybersecurity, to share best practices, find ways to collaborate, and work to achieve common goals.

Along with the United States, the European Union also runs a month-long cyber awareness campaign in October, with the initiative having started back in 2012. The aim of this advocacy campaign is similar: promoting cybersecurity among citizens and organizations, and providing information on available tools and resources. Watch our CTO speak to some of the main considerations around Continue reading

Website update: Experiencing problems with translations into French and Spanish

I must apologize to readers of our French and Spanish versions of our website. We are currently experiencing a problem with our usage of the WordPress Multilingual (WPML) plugin that is preventing us from sending our new content out for translation.  It is proving to be quite difficult to identify and fix the issue. We are working with our development team, our hosting provider, and the WPML support team to find the solution. I hope that in the next couple of days we can solve this and return to our regular publishing in three languages.

Thank you for your patience.

P.S. Those who want more of the technical details can see the open WPML support ticket. You are also welcome to contact me directly at [email protected].
