Ensure Application Availability

Improve the availability of applications affected by overloaded or unavailable infrastructure.

Users expect their mission-critical applications to be online and performant at all times. Application downtime is affected by three main factors:

  • Traffic overloading origin server capacity, making it unavailable or unresponsive
  • Origin servers experiencing unplanned downtime due to failure or misconfiguration
  • Manual, error prone disaster recovery and in-house load balancing resulting in downtime or high operational costs

While the dollar costs for downtime may vary by company size or industry, the severity of business impact is growing across all businesses. According to an IDC report in 2015, the average cost of infrastructure downtime is $100k per hour.1

Internet applications require the scale and resilience of global network infrastructure to combat spikes in traffic and unplanned downtime or outages. Performance and reliability services must incorporate security to stop new and sophisticated attacks, while ensuring fast onboarding and easy-to-configure functionalities that prevent downtime introduced by maintenance, outages, and misconfigurations.

Global Scale

Cloudflare’s global Anycast network consisting of 154 data centers spans across 74 countries, offers a scalable infrastructure backbone that prevents downtime and unavailability.

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 availability and performance of Internet applications and APIs.

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 Application Availability

Traffic Overload

Both expected and unexpected network congestion or overloaded infrastructure can degrade performance to a point where websites or applications stop responding.

Unplanned Downtime and Failures

Applications or individual origin servers can experience unplanned downtime and hard-to-troubleshoot outages, preventing visitors from accessing assets. Unplanned downtime includes hardware failures or system failures due to misconfiguration.

Disaster Recovery and In-House Load Balancing

Assets can also go offline for reasons unrelated to the network, such as manual and error prone disaster recovery or in-house load balancing, resulting in often hard-to-troubleshoot outages involving expensive triage.

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 154 data centers across 74 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 154 data centers around the world.
  • Mobile SDK

    Cloudflare’s Mobile SDK provides visibility into application performance and load times across any global carrier network.

Security

Cloudflare Security Services reduce the risk of lost customers, declining revenues, and degraded brand by protecting against DDoS attacks, abusive bots, and data breach.

  • Anycast Network

    With 154 data centers across 74 countries and 20 Tbps of capacity, Cloudflare’s Anycast network absorbs distributed attack traffic by dispersing it geographically, while keeping Internet properties available and performant.
  • DNSSEC

    DNSSEC is the Internet’s non-spoofable caller ID. It guarantees a web application’s traffic is safely routed to the correct servers so that a site’s visitors are not intercepted by a hidden “man-in-the-middle” attacker.
  • Web Application Firewall (WAF)

    Cloudflare’s enterprise-grade web application firewall (WAF) detects and block common application layer vulnerabilities at the network edge, utilising the OWASP Top 10, application-specific and custom rulesets.
