The Workers team here at Cloudflare has been hard at work shipping a bunch of new features in the last year and we’ve seen some amazing things built with the tools we’ve provided. However, as my uncle once said, with great serverless platform growth comes great responsibility.
One of the ways we can help is by ensuring that deploying and maintaining your Workers scripts is a low risk endeavor. Rotating a set of API keys shouldn’t require risking downtime through code edits and redeployments and in some cases it may not make sense for the developer writing the script to know the actual API key value at all. To help tackle this problem, we’re releasing Secrets and Environment Variables to the Wrangler CLI and Workers Dashboard.
Supporting secrets
As we started to design support for secrets in Workers we had a sense that this was already a big concern for a lot of our users but we wanted to learn about all of the use cases to ensure we were building the right thing. We headed to the community forums, twitter, and the inbox of Louis Grace, business development representative extraordinaire, for some anecdotes about Secrets usage. We also sent Continue reading
Impact of Cache Locality
In the past, we didn't have the opportunity to evaluate as many CPUs as we do today. The hardware ecosystem was simple – Intel had consistently delivered industry leading processors. Other vendors could not compete with them on both performance and cost. Recently it all changed: AMD has been challenging the status quo with their 2nd Gen EPYC processors.
This is not the first time that Intel has been challenged; previously there was Qualcomm, and we worked with AMD and considered their 1st Gen EPYC processors and based on the original Zen architecture, but ultimately, Intel prevailed. AMD did not give up and unveiled their 2nd Gen EPYC processors codenamed Rome based on the latest Zen 2 architecture.

This made many improvements over its predecessors. Improvements include a die shrink from 14nm to 7nm, a doubling of the top end core count from 32 to 64, and a larger L3 cache size. Let’s emphasize again on the size of that L3 cache, which is 32 MiB L3 cache per Core Complex Die (CCD).
This time around, we have taken steps to Continue reading
The Myth of Scaling From On-Premises Data Center into a Public Cloud
Every now and then someone tries to justify the “wisdom” of migrating VMs from on-premises data center into a public cloud (without renumbering them) with the idea of “scaling out into the public cloud” aka “cloud bursting”. My usual response: this is another vendor marketing myth that works only in PowerPoint.
To be honest, that statement is too harsh. You can easily scale your application into a public cloud assuming that:

Ostinato – Packet Generator – Test your broadcast and mitigation strategies
I used ostinato long before when it was in early stages probably, at that point I never had any real need to use a packet generator as the place I was working was already equipped with IXIA and Spirant best in Class Packet generators.
https://ostinato.org/ – is the link
Whats the use case – Well I wanted to test LSP loadbalancing and also specific scenario of BUM traffic and how well it can be contained lets say in Switching level QFX and also VPLS level
Its doing a good job, though it started as open source, author now sells it with some minimal fee to keep up with the development costs.
You could also use scapy and i wrote a small program to do this , problem is scapy sorts of waits for some of the responses and i have not yet figured out what needs to be solved there
Testing Ostinato on QFX and its really good so far. Storm control got in and stopped transmitting any packets through the interface.
At the end, this is a nice to have tool for any sort of packet crafting and limited scale testing for proof of concept scenarios.

7 Wedding Professionals Networking Group Members
Wedding Planners
Wedding planners are the most essential people in a wedding professionals networking group.

So you definitely want to include wedding planners in your networking group.
Bridal Shop Owners or Wedding Dress Makers
Another essential person in a wedding professionals networking group is the person who runs a bridal shop or makes wedding gowns and bridesmaid dresses, since these professionals work closely with the bride and often are asked to suggest other wedding vendors.
