Accelerate Internet Applications

Deliver fast, rich user experiences for Internet applications that increase engagement and conversions, while reducing costs.

Consumers expect fast and reliable access to their online experiences. Internet application latency and rising infrastructure costs are driven by three main factors:

  • Heavy and complex web pages including dense CSS, high-quality images and video, and javascript
  • Interactive & personalized dynamic content resulting in more trips to origin infrastructure
  • Globally distributed users requiring longer trips to origin infrastructure

Google found that a mere two-second delay led to more than a 4.3% loss in revenue per visitor,1 and a one-second delay led to a decrease of 7% in conversion.2 Slow-loading Internet applications result in degraded brand perception, reduced lifetime customer value, and near-term financial impact, such as lower revenues and higher operational costs.

Internet applications require the speed and scale of global network infrastructure to combat increasing latency and rising operational costs. Performance services must incorporate security functionalities to protect against new and sophisticated attacks, while making it easy to configure fine-grained changes for complex use cases.

Global Scale

Cloudflare’s global Anycast network consisting of 155 data centers spans across 75 countries, reducing latency and time to first byte by delivering content closest to visitors.

Ease of Use

Setting up Cloudflare takes as little as 5 minutes. The easy-to-use dashboard enables quick configuration of fine-grained functionalities to improve the performance of complex applications.

Integrated Security & Performance

Cloudflare includes integrated security services to defend against DDoS attacks, customer data breaches, and abusive bots, while preventing performance trade-offs.

Challenges Affecting Performance

Network characteristics that can impact performance: the number of roundtrips to establish a connection, number of requests, latency of packets (distance or throughput), client-side render times, and varied payload sizes. Additionally, the following factors can affect Internet application latency:

Heavy and Complex Web Pages

The average page size continues to increase, whether it is because of complex CSS, high-quality images and video assets, or extensive usage of javascript snippets. The average size of websites continues to increase, from 2011 to 2017 the average page size has increased by almost 3x.3 Larger web page sizes (the ‘payload’) increases the amount of data which must travel over the network to be rendered by the visitor’s browser, slowing down loading speeds.

Interactivity and Personalization

When applications use APIs to fetch dynamic content to support personalization and interactivity, the number of connections and trips to origin infrastructure increases, resulting in performance degradations and poor visitor experiences.

Globally Distributed Visitors

As modern web page visitors become more globally dispersed, content must travel longer distances, sometimes to countries with slow or unreliable networks. For example, a website with an origin server in San Francisco might have an equal number of global visitors as it does local and global visitors will experience increases in latency.

Every Cloudflare data center runs an integrated stack of performance features which address the most common causes of poor performance. These features help solve many of the core problems that slow down the delivery of applications over the Internet. From fast web address lookups to accelerated delivery to the origin server, Cloudflare speeds up traffic at keys points in the life of a request.

Cloudflare Features

Cloudflare's Performance and Security Services work in conjunction to reduce latency of websites, mobile applications, and APIs end-to-end, while protecting against DDoS attack, abusive bots, and data breach.

Performance

Cloudflare Performance Services improve conversions, reduce churn, and improve visitor experiences by accelerating web and mobile performance, while keeping applications available.

  • Content Delivery Network (CDN)

    With 155 data centers across 75 countries, Cloudflare’s Anycast CDN caches static content at the edge, reducing latency by delivering assets as close as geographically possible to visitors.
  • Website Optimizations

    Cloudflare includes a suite of web optimizations to improve the performance of Internet assets. Optimizations include the latest web standards, such as HTTP/2 and TLS 1.3, as well as proprietary enhancements for images and mobile device visitors.
  • DNS

    Cloudflare is the fastest managed DNS provider in the world, routing over 39% of all global DNS traffic. Cloudflare has multiple ways to achieve maximum performance for online assets.
  • Load Balancing

    Cloudflare Load Balancing provides load balancing, geo-steering, monitoring and failover for single, hybrid-cloud, and multi-cloud environments, enhancing performance and availability.
  • Argo Smart Routing

    Argo Smart Routing improves Internet asset performance on average of 35% by routing visitors through the least congested and most reliable paths on Cloudflare's private network.
  • Railgun

    Railgun compresses previously uncacheable web objects up to 99.6% by leveraging techniques similar to those used in the compression of high-quality video. This results in an average 200% additional performance increase.
  • Stream

    Cloudflare Stream makes streaming high quality video at scale, easy and affordable.
  • Workers

    Cloudflare Workers let developers run JavaScript Service Workers in Cloudflare's 155 data centers around the world.
