In my last blog post, I discussed why you should use a content delivery network. But after you’ve decided to start using a CDN, you’ll need to pick out the right CDN for your business.
TLS at the edge and server-side security
We’re huge fans of Transport Layer Security (TLS) at Fastly. Here’s a behind-the-scenes look at how we do encryption at the edge, which can also serve as overall best practices for handling server-side TLS.

This article dives into our support team's training processes and explains how our lessons learned can help your support team grow.
What Is a CDN and Why You Should Use One
A content delivery network (CDN) is a way to deliver content from your website or mobile application to people more quickly and efficiently, based on their geographic location.
How our solid-state drives result in cost savings for customers
Solid-State Drives (SSDs) are semiconductor-based storage devices that save persistent data by using NAND flash memory. See how Fastly manages caches with SSDs and how you can save.

At Fastly, we've made some key decisions about how to operate and structure our support team in a way that allows us to deliver quality at scale. Some of the lessons we learned are more specific to issues encountered as we grew, but most can be applied to any support or customer-facing team.
Getting an A in security: SHA-2 migration and disabling RC4

Boost Cache Efficiency with Origin Log Analysis
If you want to increase the efficiency of your Varnish (or Fastly) cache, you need to figure out what traffic is not cached. By definition, any traffic that reaches your origin is not cached, and thus worthy of investigation.
How Fastly builds support, part 2: The customer experience
What customers encounter when evaluating and onboarding with Fastly isn't arbitrary. It's an experience that we've intentionally crafted. This post will discuss what customers experience, and what we have in place to make sure it happens every time, for every customer.
Securing the news: TLS for media sites
TLS is especially applicable to news sites. News organizations bear a public responsibility to accurately report the news, and need to take the steps necessary to ensure credibility. The security of online news content is one of the first steps in verifying its veracity while protecting readers.
How Fastly Builds Support, Part 1: Our Standards
In the time I've been at Fastly, we've had enough customers and friends ask us about how we do support and what's going on under the hood that it seems appropriate to give a high level overview of how we build, what we've learned, and how other teams can borrow from our setup.

Normalizing the Host Header
In the continued quest to increase cache hit ratios, the chant is: "Normalize, normalize, normalize." Less variation in your requests means you have a higher chance of getting hits. This month's highlight is the Host header.

Security, compliance and transparency are very important to us at Fastly, and these updates will help protect our customers as well as our company.
Caching the Uncacheable: CSRF Security

Accelerating Rails, Part 1: Built-in Caching
Caching is one strategy that helps ease scaling pains that I often see Rails developers overlooking. Starting out with caching can be confusing, because terms and documentation can be convoluted, especially if you’re not an expert.
Using ESI, Part 2: Leveraging VCL and ESI to Use JSONP
In this post, I’m going to discuss how you can leverage ESI and VCL (Varnish Configuration Language, the domain-specific language that powers Fastly’s edge scripting capabilities) to use JSON responses, even when they’re loaded from another site. This is useful in many cases, including various analytics and social sharing instances.
