In an era where every business is going online, competition is getting fierce, and every second starts to matter. Every microsecond started to become extremely important, success started to get defined by margin of a microseconds.
As a website owner, you have taken extreme care when choosing your web host. You might have chosen the best onshore web hosting, and might have opted for the absolute best VPS available at the time. Yet, if your business grows beyond the borders and your business starts to serve a fraternity that is in the opposite part of the world, you need to keep your performance intact.
This is where CDN (Content Delivery Networks) starts to play. CDNs are a geographically distributed network of proxy servers and their data centers. Their goal is to provide high availability and performance by distributing services spatially relative to the users. CDN came into existence during the late 1990s, when the internet started to become mission critical for businesses, to alleviate the performance bottleneck.
What are the benefits of having CDNS?
- Improving website load times – distributing contents closer to website visitors by using a nearby CDN server can highly reduce website loading time. Improved website loading time can highly reduce the bounce rates, and increase the amount of time people spend on the site. In simple words, a faster visitor attracts more visitors and they stick around longer.
- Reducing bandwidth costs – The server costs increase proportionally with visitors, and with the type of hosting Stakque Infotech uses for the client, it is important to use caching and other optimization that CDN employs. CDNs can efficiently reduce bandwidth costs.
- Increasing content availability and redundancy – When compared to origin servers, CDN servers can withstand more incoming traffic, thanks to their distributed nature. Although, CDNs can be an SPF (Single point of failure).
- Improving website security – CDN may improve website security by several optimizations and may be by employing DDoS mitigation etc. Also, since the end-users are interacting more with the edge servers for the static content, the origin server has a reduced chance of catching errors and becoming prone to attacks
