There are several places where you might have come across the term CDN or Content Delivery Network. If you have used a private blog network or have plans of using one then you might receive recommendations of masking the IP with a CDN. So what exactly is a content delivery network? Why should you start using a CDN today?
An overview of CDN
You might already have interacted with a CDN without explicitly using the term. This is where the geography aspect comes into the picture in the allocation and use of servers. Internet users get to view content that is cached in the nearby servers to speed up the loading times. The latency of the network also drops significantly when a CDN based structure is used.
How does a CDN work?
This works by establishing servers in location clusters where the requests originate from. Therefore when a user requests for a resource on the website it will pull it from the cached version on the closest server to the user. Even if the local cache misses a detail the CDN will fetch and distribute the requested information from the original source. Therefore, the overall loading times are improved.
CDN hosting and conventional web hosting – the differences
CDN hosting is where the website access speeds are better. CDN hosting doesn’t distribute the whole of the content like a conventional web hosting system. CDNs present the assets that take the shortest time to load. Instead of using one server as with traditional web hosting, CDN uses multiple hosts.
What are the perks of using a CDN?
1. Hosting multiple websites
CDN’s are perfect when wanting to host multiple websites in the same environment. There are ways to host them so you don’t have any footprints across your sites. Normally when you host multiple websites on the same hosting account it’s very clear they are owned by the same person. Services like LaunchCDN allow you to host an unlimited amount of sites using this method to “mask” the hosting of the website and make sure that there are no footprints.
When CDN picks information from the local hosts that cache the files the main server is not at risk. CDN helps avert attacks on the DDoS and incorporates more relevant internet security measures. Therefore businesses can avoid the risk of huge losses incurred from data center attacks. There are also overall data security benefits that businesses can reap from making use of a CDN. If you stick with a reliable CDN provider then you can also enjoy better encryption and therefore tackle content delivery in a secure fashion.
3. Budgeting benefits
Even small businesses find CDNs to be long term cost-effective investments. It provides a scalable solution for growing businesses. Therefore you need not start from scratch once your business goes through a growth phase. You do not have to worry about large expenditures in hosting servers abroad as CDN helps deliver your content across the globe for near zero cost.
4. Bid adieu to network latency
Depending on the round trips and the other parameters of the server, the latency of the network can vary. This, in turn, determines the loading times and the packet loss encountered in the process. CDN helps in loading your website fast by significantly lowering the network latency. Remember that your website loading time also has a major role to play in the conversion rates. Therefore for reliable loading speed and better optimization CDN can help.
