Cloudflare

Two of my favourite developer things these days are Azure Functions [https://www.troyhunt.com/azure-functions-in-practice/] and Cloudflare Workers [https://scotthelme.co.uk/cloudflare-workers-report-uri/]. They're both "serverless" in that rather than running on your own slice of infrastructure, that concept is abstracted away and you get to focus on just code executions rather than the logical bounds of the server it runs on. So for example, when you have an Azure function and you deploy it und...

In the immortal words of Ricky Bobby, I wanna go fast [https://www.youtube.com/watch?v=_qJGsSuFRIg]. When I launched Pwned Passwords V2 last week [https://www.troyhunt.com/ive-just-launched-pwned-passwords-version-2/], I made it fast - real fast - and I want to talk briefly here about why that was important, how I did it and then how I've since shaved another 56% off the load time for requests that hit the origin. And a bunch of other cool perf stuff while I'm here. Why Speed Matters for Pwned...

It has a cool name and a logo - this must be serious! Since Heartbleed [https://en.wikipedia.org/wiki/Heartbleed], bug branding has become a bit of a thing and more than anything, it points to the way vulnerabilities like these are represented by the press. It helps with headlines and I'm sure it does wonderful things for bug (brand?) recognition, but it also has a way of drumming up excitement and sensationalism in a way that isn't always commensurate with the actual risk. That said, the Cloud...

We've all had bad neighbours before. Perhaps they were noisy, maybe the kids ran riot or they could have been just continually snaring all the visitor parking spots in your apartment building (bastards). But last week, someone popped up with another bad neighbour story which was quite different to usual... Fellow MVP Paul Cunningham runs a blog over at paulcunningham.me [https://paulcunningham.me/] and for the most part, it looks like any other ordinary blog: Now being a forward-thinking blo...

I wrote recently about how Have I been pwned (HIBP) had an API rate limit introduced and then brought forward [https://www.troyhunt.com/content-images-2016-09-a-one-week-traffic-snapshot-1-png/] which was in part a response to large volumes of requests against the API. It was causing sudden ramp ups of traffic that Azure couldn't scale fast enough to meet and was also hitting my hip pocket as I paid for the underlying infrastructure to scale out in response. By limiting requests to one per every...

Let's start with a quick quiz: Take a look at haveibeenpwned.com [https://haveibeenpwned.com/] (HIBP) and tell me where the traffic is encrypted between: You see HTTPS which is good so you know it's doing crypto things in your browser, but where's the other end of the encryption? I mean at what point is the traffic decrypted? Many people would say it's at the web server but it's not, it's upstream of there at Microsoft's appliances that sits in front of the web application PaaS offering. You...

It's been 434 blog posts over six and a half years. It's gone from being excited about a hundred visitors in a week to hundreds of thousands on a big day. It's taken me from a hobby to a career. In so many ways, this blog has defined who I am and what I do today but finally, it was time for a change. You're now reading an all new blog in an all new design on an all new platform. The content is the only thing that remains and I've literally rebuilt everything from the ground up over the last few...

This content is now available in the Pluralsight course "Getting Started with CloudFlare Security" [http://www.pluralsight.com/courses/cloudflare-security-getting-started]As you may be well aware by this, Microsoft’s Azure gets me rather excited [https://www.troyhunt.com/search/label/Azure]. That’s not without merit IMHO, it’s a sensational product for all the reasons you can read about in the blog posts at the end of that link. Almost without exception, when I get a question about Azure I have...
