This article explains how building a content delivery network (CDN) with multiple data centres is the best way to ensure that you can deliver your website around the world at high speed, while simultaneously protecting your website against downtime.
A CDN is a globally distributed network of servers that deliver content on behalf of your website or application. Content delivery networks provide fast, reliable and secure access to websites and applications by serving them from locations close to their users.
A data center is a facility used for housing computer systems and associated components, such as telecommunications and storage systems. A data center can be as small as one room with a few hundred square feet of floor space (or less), or as large as several thousand acres with 100,000 square feet or more of floor space. The term "data centre" can also refer to a physical location where back-end processing occurs in an organization's IT infrastructure architecture - called cloud computing infrastructure - which may include multiple interconnected buildings under the same roof. The owners of these facilities have traditionally provided power, cooling services and other essential colocation resources to tenants in exchange for payment.
The risk of losing all your data if a data centre fails is a real one. It's also the reason why it's so important to have multiple data centres spread out across the world.
Just last summer one of the data centers owned by OVH in Europe had a major fire outage that resulted in 1000s of the loss of the whole facility.
If you're experiencing similar risks and want to ensure that your content delivery network remains stable and secure, then you may want to consider building a scalable, reliable, and secure CDN solution that uses multiple data centres around the world.
It's not an easy task by any means but it will allow you to build up resources in case one data centre goes down.
There are many benefits to having multiple data centres:
More redundancy - If one of the servers goes down, there is another one to take its place so that no user has to suffer downtime or lose their connection due to technical problems. This also provides security by ensuring that there is always enough capacity to handle the demand of traffic at any given time without overloading any servers at once (e.g., during peak hours).
Flexibility - With multi-DC support comes the ability for companies like MS Azure or Amazon Web Services (AWS) to redirect all traffic to a different zone in case of emergencies or connection issues.
Your users may have noticed that when they get to your website or app it's served from different locations at different times --- this is because of caching. For example, if a user lives in New York City and regularly uses your service at work or home, they will likely see different IP addresses (the unique identifier assigned to each computer on the internet) over time even though they are accessing the same website or app server. This is because their ISP caches webpages for their customers' convenience so that when someone visits a site for the first time it isn't necessary for them to download all of its content again; instead, the ISP serves up what's already stored locally (hence why some websites load much faster than others).
While this might sound like a complex process, it's actually quite simple: A CDN helps protect you from threats such as DDoS attacks by making sure that requests for your content get sent to different servers around the world. This cuts down on the likelihood of any single server being affected, since it will receive fewer requests.
CDNs are designed to do this automatically, so you don't need to do anything special in order for your site's security measures to work.
Multiple data centres are often the key to building a scalable, reliable, and secure content delivery network. In fact, having multiple data centres can help you ensure that your content remains available even if your primary location fails.
Content delivery networks (CDNs) play an important role in ensuring that web users have access to fast connections when it comes to streaming videos or downloading large files like images and multimedia files. To achieve this level of performance, CDNs need to be able to cache as much data as possible close to end users so they don't have to make requests across long distances every time they want something loaded onto their device or browser window.
In the end, a network is only as strong as its weakest link, and you can't afford for that to be your website's infrastructure. So make sure that you're using multiple data centres to deliver content around the world from different locations so it can be served faster and more reliably than ever before!
