Why a Resilient Content Delivery Network (CDN) is Key to Website Performance

Today’s online users have set certain quality standards when visiting a website. They expect a high performing website with fast page load times and easily accessible, fresh and dynamic content. They also expect to enjoy a seamless and secure experience with no downtime or throttling of content access. As for website managers, they strive to provide the most enjoyable digital user experience for their customers by delivering fast response times and strong website performance, even in times of high traffic and under stress. security attack.

To achieve this, websites must be scalable and resilient. They must be equipped to deal with when things go wrong, in the event of a DDoS Where robot attack, or when things are going well and they experience a sudden spike in traffic to a website.

“Resilience” is the ability to “bounce back” quickly after a crisis or, as the oxford dictionary defines it, “the ability to recover quickly from difficulties” or “the ability of a substance or object to regain its shape; elasticity”.

For website managers, a solid content delivery network (CDN) provides that elasticity for their site to ensure the levels of availability, speed and performance that customers expect, whatever the circumstances.

Content Delivery Network for faster response times

A Content Delivery Network (CDN) is a data center network that work together as a single service that delivers performance benefits to both application users and operations. Benefits include faster and more consistent response times, typically achieved by simultaneously streaming content from local data centers with closer physical proximity to end users than the origin server, thereby reducing transit time and distance.

Imperva’s CDN offers advanced content caching, load balancing, and custom rules, all in a single, secure stack Web Application and API Security (WAAP) to ensure that content from our customers’ websites and applications is delivered securely and consistently around the world.

Super fast and efficient access to dynamic web content

Imperva CDN uses advanced caching techniques to speed up site speed and improve customer experience. Intelligent caching functionality such as Smart Cache leverages machine learning to efficiently cache dynamically generated pages by tracking content usage patterns and automatically optimizing storage and delivery. Benefits of Smart Cache include cache adjustment for popular regional content and automated cache rules for frequently accessed documents. And there are also savings to be made. Automatic caching of frequently used content saves costs by reducing bandwidth usage.

Distribution and scalability on a global network

load balancing Delivers greater operational efficiency to your application delivery by distributing user requests between data centers and origin servers for best performance and response times. In addition, it helps ensure site availability in the event of a server or data center malfunction by routing traffic to a healthy server. Imperva uses advanced load balancing algorithms to ensure that requests are always routed to the origin server with the smallest load. This evenly distributes the load across the origin servers to improve performance and enable scalability. The Imperva load balancer also plays a major role in Disaster recovery planning acting as an automated solution for site failover. When selecting a load balancing solution it’s important to assess what best suits your infrastructure, availability, and growth strategy.

Improve site speed and manage traffic during peak hours

Other benefits of Imperva CDN include Content Optimizationsuch as minification and compression, to improve page load times and increase site speed while the Imperva waiting room helps you better manage traffic to your website during peak hours by allowing you to place them in a virtual queuing system to access your site. The Waiting Room prevents sites from dropping out and keeps your customers on your site, which ultimately leads to higher conversion for transactional or retail sites.

Built within a WAAP platform resiliency

Of course, the Imperva CDN is built within our single-stack WAAP platform which builds site resiliency by combining WAF and API Security, DDoS Protection and Protection against robots all in one complete platform. Websites are protected against the latest security threats, preventing costly downtime and recovery due to cybersecurity attacks aimed at overwhelming the application, such as a DDoS or Bot attack.

Custom rules for speed and security of delivery

With security in mind, one of the key features of our CDN is our custom rules engine which offers self-service rule customization to allow you to quickly adapt to the needs of your environment and make quick decisions in based on visit and request attributes without changing the user-visible URL. The rules engine offers features like ResponseHeaderOverride which not only provides faster response times but also gives your website a real security boost by protecting it from vulnerabilities like Cross-site scripting and Clickjacking.

Ultimately, the CDN you choose will be the driving force behind your website, giving you precise control over your site’s performance, speed, and resiliency, which is what your customers expect.
