5 Reasons Why App Providers Choose CacheFly CDN

If you want your app to be successful, offering your end-users fast downloads and page loads—completely loaded—as quickly as possible, is one of the most important aspects your business depends on.

But when high traffic and overloaded servers cause delays and downtime for mission-critical apps, it’s a no-win situation. You cost your customers money—and you wind up with churn and revenue loss.

App Delays Cost U.S. Companies up to $7.5 billion per year.

In Nimble Storage’s recent Mind the Gap survey of 3,000 IT Decision Makers and business users, 76% reported that the speed of apps have a significant impact on their ability to perform their best in the workplace. What’s more alarming, the study found that U.S. companies may be losing as much as $7.5 billion a year in worker productivity drains—from app-performance delays and downtime.

App Providers Use CDNs to Improve User Experience.

With a CDN, you can ensure your end-users a faster, more improved user experience—while focusing on your business instead of worrying about delivery performance. However, not all CDNs are built alike. What you need to look for, is a reliable CDN with consistently low error rates, high throughput delivery performance, and high availability.

Here are five reasons app providers choose CacheFly CDN.

1.) Fastest Throughput Performance.

Any CDN can claim to be fast. But when it comes to throughput—the real indicator of CDN performance (the total time it takes from initial request to fully rendered page/download), most CDNs fall flat. With a network built for throughput, CacheFly’s proven global throughput performance ensures the fastest delivery of your apps—no matter the file size, or where your users are located.

2.) 100% Availability SLA

CacheFly ensures the highest availability and guarantees continuous network uptime, 100%.  No scheduled or unscheduled maintenance. Even in the event of a power outage, network issues or hardware issues, CacheFly’s instant failover automatically reroutes to the nearest available servers.

3.) Infinite Scalability

What happens when your app gets featured in the app store? Can your origin server withstand millions of requests? You need a CDN that can easily scale to accommodate spikes in traffic. No matter how popular your app gets, rest assured. CacheFly is built to infinitely scale on demand.

4.) Super-Fast Replication

While some CDNs can take hours to up to 24 hours to push updates, CacheFly’s super-fast replication to pushes your app updates to end-users within seconds.

5.) Robust Security

With security features such as HTTPS support, URL/referrer blocking, and origin shielding, CacheFly CDN securely serves your app’s content and enables you to block unauthorized downloads and control access to subscription content.

“No one launches a serious consumer web business without a CDN anymore. You’ll get killed. Modern web users expect the fastest possible load times or else they’re immediately headed to a competitor. With CacheFly…I can say that we rarely, if ever, need to think about whether or not it is operating according to our expectations.”

Varnish and CacheFly Webinar Archive Now Available

In case you missed the Using Varnish for Future-Proof Caching webinar (originally recorded on Thurs., April 21st), an archive is now available.

The webinar, presented by CTO and Founders, Per Buer of Varnish Software, and Matt Levine of CacheFly, focused on how CacheFly is using Varnish Plus to turbocharge deliver performance.

During the webinar, Matt Levine shared:

  • How CacheFly used Varnish Plus to massively improve performance on “in-flight” objects.
  • How more granular control over caching and more flexibility allows CacheFly to deliver better customer service.
  • How features can now be added or changed within minutes—not days, while ensuring functionality is maintained in a timely fashion.
  • How CacheFly has saved both monetary and manpower resources after implementing Varnish Plus.

Announcing CacheFly CDN—Turbocharged with Varnish Plus

I’m pleased to announce that over the past year, we’ve been revamping the underpinnings of our CDN, using Varnish Plus.

What is Varnish Plus?

Varnish Plus is an enhanced version of the open source front-end web application accelerator (HTTP reverse proxy).

Why did we decide to deploy Varnish Plus?

We decided to implement Varnish Plus for two reasons:

  • Significant Performance Boost:
    When combined with our high throughput performance CDN, Varnish Plus dramatically improves our TTFB, while preserving our industry leading throughput.  Varnish Plus is also a lot more efficient on todays modern hardware, which allows us to scale out additional PoPs with less hardware.
  • Ability to Deploy New Features—Faster:
    Since CacheFly began in 2005, we’ve relied on a mix of open-source solutions with our custom patches. While this allowed us to grow and scale into the high performance CDN we have today, it’s become infinitely more challenging to deploy new features. In addition to the performance improvement, using Varnish Plus enables us to deploy new in-demand features where we can add or change features within minutes—not days, all while backing it with our 100% availability SLA.

What does this mean for customers?

We’re offering our customers a turbo-charged version of CacheFly. What has always been the fastest throughput CDN in the world, will now be even faster.  Moving forward with Q2 and beyond, we’ll be deploying some amazing new features, including HTTP/2 support!

To learn more, subscribe for updates, or register to attend Varnish Summit NYC from 9am-4pm ET, Tuesday, March 15, 2016 at Bernheim and Schwartz, where I’ll be speaking with Varnish CTO and Founder, Per Buer, in a Q&A session, starting at 2pm ET.

Push vs. Pull: What’s the Difference?

Like most CDNs, CacheFly offers two distinct methods of caching your files: “push,” which is the traditional upload method, and origin “pull,” also known as reverse proxy.

Here, we will explain the differences so you can understand and select which option will work best for your type of environment.

Reverse Proxy/Origin Pull

With CacheFly’s reverse proxy, you define an origin domain where CacheFly will automatically “pull” files from as needed.

reverse proxy cachefly cdn

For example with the reverse proxy option, the first time an end-user requests a file and it isn’t already loaded on our CDN (this is known as a “cache-miss”), CacheFly will request that file from your origin domain to fulfill the user’s request. This is a seamless process that happens “on the fly.” After CacheFly retrieves the file from your origin domain, future requests for that file will be served from the CDN cache. That’s how reverse proxy/origin pull works.

Updates to previously cached files are determined by your website’s HTTP cache headers (expires or max-age). If you rather not wait for the object to expire, CacheFly allows you the option to purge the file from CDN cache from within the customer portal or via an API call.

Benefits of using a Reverse Proxy/Origin Pull method:

  • Easier to configure
  • Updates content as requested (by a cache miss)
  • Real-time purging of objects (250ms!)
  • Optimal for content providers with high traffic and lots of small files.


Upload/Push

Instead of waiting for the first request from the user to pull and cache files to CacheFly CDN servers, your other option is to simply upload, or “push” your files to ftp.cachefly.com. Your FTP login credentials are displayed on the welcome page of the customer portal. Once you’ve transferred your files to ftp.cachefly.com and your uploading client has issued a disconnect (FTP QUIT), your files will be available from your CacheFly given subdomain.

Updates to previously uploaded objects will be reflected at the edge within a few minutes while new/uncached files will be ready for use shortly after disconnecting from your upload session.

Benefits of using Upload/Push method:

  • Optimal for content providers with large files downloads (e.g. podcasts)
  • No ‘stampede’ effect to origin server
  • Guaranteed QoS for throughput, even on first request
  • No need to purge objects
  • Easily automate uploads using rsync

If you’re still unsure, feel free to contact us at support@cachefly.com. We’re always happy to help you figure out which method of synchronizing your files is right for you.

Using Cedexis, TopTenReviews found CacheFly  best in highest average response time and lowest error rates.

To accurately measure performance metrics with Cedexis, TopTenReviews was able to pull data from actual end users of CDN providers to gain insight into real-time performance metrics available to the public. In addition, the independent reviewer, obtained test accounts with each CDN provider for access to each control panel—to evaluate overall usability on features, such as reporting and analytics.

CacheFly is no stranger to high marks on performance. In 2014, CloudHarmony, a cloud performance benchmarking provider, released its “Cloud Speedtest,” testing average latency and throughput performance of major CDN providers for a 4-year span, from 2011-2014. The report found CacheFly CDN, #1 in overall global throughput performance—for both small and large file throughput.

In 2010, Paessler, a leading worldwide network monitoring software provider, conducted a “Real World” Performance Comparison of Content Delivery Network (CDN) Providers, monitoring the performance of 24 CDN and cloud providers using their own Internet connection. The findings determined CacheFly to have performed the fastest in all four categories (1st and average request time, globally and USA).

TopTenReviews’ criteria for reviewing and comparing CDNs included average response time (in milliseconds), error rate, Points of Presence (overall and USA only), real-time reporting, full Gzip compression support, instant activation, transparent pricing, contract-free, API support, control panel, static file delivery, video streaming, storage, multi-CDN compatibility, software distribution, game publishing, dynamic content acceleration, support of shared and custom SSL certificates, security threat protection, token authentication, support, and 100% uptime guarantee.
