FAQs
What is Static Content
Static content can be delivered to an end-user without having to be generated, modified, or processed. The server delivers the same file to each user, making static content one of the simplest and most efficient content types to be transmitted via a CDN.
What is Dynamic Content?
Dynamic content is the term used to describe site content that automatically adapts to various pre-defined conditions, such as particular user signals. The content featured on the website will adjust dynamically so that different users see different content. Dynamic web page: example of server-side scripting (PHP and MySQL).
Who needs CDN?
CDN services are beneficial for websites that need to deliver fast, secure, and reliable content globally. Here are some examples:
E-commerce sites: Improve loading times and security, especially during high traffic.
Financial institutions: Ensure secure, fast transmission of sensitive information and protect against DDoS attacks.
Media or news sites: Deliver content quickly and efficiently, even with dynamic updates.
Government websites: Provide faster services to citizens with heavy content.
Mobile apps: Enhance load times and responsiveness.
SaaS businesses: Scale easily while maintaining performance for millions of users.
A CDN is ideal if you have a global audience or need to improve website performance and security.
Why should we use CDN?
CDNs improve website performance by reducing load times and latency, distributing content from the nearest server. They help manage traffic peaks, enhance security through encryption, and protect against DDoS attacks. CDNs also integrate the latest transmission technologies, offer valuable analytics, and improve SEO. They are cost-effective and enable fast global expansion, making them ideal for e-commerce, financial institutions, media sites, government agencies, mobile apps, and SaaS platforms.
What is Anycast DNS?
Anycast DNS is a networking technique that allows the same IP address to be advertised from multiple locations. When a user makes a request, the network directs it to the nearest or most optimal server based on factors like distance, latency, and server health. This reduces latency, enhances load balancing, and simplifies configuration management. It is widely used in CDNs to deliver content faster by routing traffic to the closest server, ensuring better performance and resilience. Anycast DNS also improves security, offering better defense against DDoS attacks and providing detailed traffic analytics.
What is Hybrid CDN?
Hybrid CDN is the solution for a medium-sized company. It basically means you are still using third-party CDN. But on the top of that content delivery, you are going to build your own platform, so you are boosting that third-party CDN. That is because commercial CDNs just simply provide a service for you and hundreds of other companies. So they can’t analyze performance for your personal use case If you want to make sure you are optimizing your content delivery you have to do yourself.
A Hybrid CDN mixes Private and Public CDNs to deliver live and Video-on-Demand content. It optimizes the cost, performance and resilience of your video service. Public CDN provides high availability. Private CDN provides cost-effective scalability.
What is the difference between push and origin pull method?
There are two methods for content distribution in CDN: Origin Pull and Origin Push. Based on how you would like to place your content on CDNs edge servers, you can choose one of them.
In the Origin Pull method, after deploying CDN on your origin server, the first request for the content will be retrieved from your origin server. Then it is cached and served to the requester. Next requests for the same content will be served directly from CDN’s Edge servers. In this method, you don’t need to transfer your content to CDN’s edge servers.
In the Origin Push method, you need to transfer your content to CDN. The transfer can be done using different methods such as FTP. Then CDN distributes these contents to edge servers.
How does CDN affects SEO?
CDNs improve SEO by:
Faster Page Load Speed: Google ranks faster sites higher, improving user experience and reducing bounce rates.
Lower Bounce Rate: Faster loading keeps users on the site longer, benefiting SEO.
HTTPS and HTTP/2: CDNs speed up HTTPS, boosting security and SEO rankings.
Increased Dwell Time: Faster sites encourage users to stay longer, which helps rankings.
Optimized Images: CDNs optimize images, improving load speed and image search rankings.
In summary, CDNs enhance SEO by improving speed, security, and user engagement.
Are CDNs Valuable for Video streaming?
CDNs are highly valuable for video streaming as they improve performance by reducing the load on primary servers, lowering latency, and preventing performance drops. By delivering content from geographically closer servers, CDNs provide a smoother, faster experience for users, ensuring high-quality playback with adaptive streaming. This helps maintain consistent video quality even during high traffic and ensures a seamless experience for global audiences.
What is difference in video performance between streaming and progressive download?
When you store your video files on a conventional Web server and the files are downloaded through HTTP, then we are talking about “Progressive Download”. Progressive (HTTP) download is the most common method for transferring files over the Internet: when you visit a Web site, all of its elements, text and images, are transferred in this way.
Contrary to Progressive Download, Streaming is accomplished through specialized Media Servers which are optimized for transferring digital video/audio. The transference is managed by messages that are sent/received between the WebTV (Video Player) and the Media Server.
Dynamic Content Acceleration: What is FEO(Front-end Optimization)?
The term “front end” relates to the interaction between your website and a user’s browser in the context of web services. Front end optimization (FEO), which is also known as content optimization, is the process of fine-tuning your website to make it more browser-friendly and load faster.
Broadly speaking, FEO focuses on reducing file sizes and minimizing the number of requests needed for a given page to load.
During the FEO process, web designers draw a distinction between the perceived and the actual page load time. Perceived load time is considered because of its impact on the overall user experience while the actual load time is often used as a performance benchmark metric.
Are CDNs Effective for Mobile Users?
CDNs improve mobile app performance by reducing latency and ensuring faster content delivery. By caching content on globally distributed servers, CDNs minimize data travel time, resulting in quicker load times and a smoother user experience. They also optimize mobile-specific challenges like last-mile connectivity and enhance security by protecting against DDoS attacks. This leads to better app performance, increased user engagement, and higher conversions.
