Content Delivery Network
What is a CDN?
A Content Delivery Network (CDN) is a network of servers located in different data centers. Static content such as videos or images are distributed to a large number of servers. When visitors access this content, the CDN system selects a server that has sufficient processing power and bandwidth to deliver the content as quickly as possible, ensuring an optimal user experience. Each file can be stored on hundreds of servers in the CDN, ensuring reliable delivery even with high traffic.
Think of a CDN like a supermarket checkout. If you have only one checkout, a line forms and your users have to wait to check out. However, if you open hundreds of checkouts, hundreds of times more users can also be served, and long waits are a thing of the past. CDN services are operated to prevent network congestion caused by delivering large amounts of content, such as videos and graphics, over the Internet - much like traffic congestion. CDNs are now used in everything from software downloads to video streaming.
In addition, modern CDNs offer increased protection against security threats such as distributed denial of service (DDoS) attacks caused by cybercrime.
CDN for me
Why does a CDN make sense for me?
Content is served directly from the CDN, which reduces the load on your servers and ensures fast loading times. As a result, you can achieve a lower bounce rate and better placements in search engine rankings. These effects can have a positive impact on your revenue.
You need lower investment costs (capex) for servers and infrastructure and have lower operational costs (OPEX) by outsourcing operations. A CDN further protects your infrastructure from costly outages due to cyber-crime or congestion.
- Reduced capital expenditure (CAPEX)
- Lower operational expenditure (OPEX)
- Protection against cyber-crime and congestion
- Better search engine rankings
- Lower bounce rate
The performance difference
The difference in performance is easiest to explain with an example: If a video starts immediately or takes 10 seconds to load, it makes a significant difference. These loading processes are familiar to many users of websites and are indicated by the loading icons.
Performance is a critical factor in user experience for today's users who have broadband connections or 5G.
