If you need CDN drastically, but you don’t know which CDN company to choose, it’s time to ask someone for advice. Today, we’re going to share some tips and clues with you on how CDN works and how to find CDN that suits perfectly.
How CDN Works?
Before starting your CDN search, it’s vital to understand what you actually need and how CDN companies provide their services. All in all, each CDN service consists of the following building blocks:
- Caching servers
- SSD/HDD and RAM
PoPs or Points of Presence are data centers located around the world. Thanks to their presence, your final users are able to access your website quickly, even if they live on another end of the world. Each Pop consists of caching servers. This is where your cached website’s or files’ versions are stored. Caching servers keep cached files on solid disk drivers (SSD or HDD) or in random-access memory (RAM).
When you apply for CDN services, it means you ask to copy and cache your content and store it on various servers to give your final users better access to it.
How to Choose Top CDN?
The number of CDN companies is really big and sometimes it’s quite difficult to make the right choice. However, there are four basic criteria to help you to make the right choice. All CDN providers can be compared according to the following criteria:
- Functionality (the list of services a CDN company provides)
- Performance (the number of PoPs around the world)
- Support service
Before choosing any CDN provider, it’s important to understand what services you need and how much you’re ready to pay for them.
