Globally-distributing your virtual servers across different geographical centres, however, can provide you the stability you require – thus, keeping applications’ up-time level as high as possible. Unfortunately, scaling horizontally over many servers at one location is not always the solution because of unexpected data-centre problems. If your application is your business, you need to keep it accessible 24/7, if possible, almost without any interruption. One whereby data and servers are globally distributed at different areas (e.g. In order to prevent this, one must rely on and use a more dependable system architecture.

Traditional and most common application deployments depend on setups with all related components being located at the same place due to several reasons, such as:Įven if an application is served from multiple machines sitting behind load-balancers (or reverse-proxies), and even if the database is also set up in a way to offer reliability and prevent data-loss, these kind of arrangements are prone to different levels of errors, causing you, at times, downtime. Traditional Application Deployment Structure Setting Up Load-Balancers / Reverse-Proxy.

Highly-Available Application Deployment Structure.In this article, we will see how to exploit some of the truly excellent and unique possibilities offered by DigitalOcean’s global cloud server / data-centre infrastructure to have a geographically-distributed, highly-available application set-up for minimal downtime (and thus dataloss) by managing DNS responses. Unless you are willing to spend a little fortune on hardware and infrastructure costs, working with DNS to achieve high-availability is probably an excellent way to go. Albeit one of the more controversial techniques, a good method to geographically distribute your application by taking advantage of your provider’s global presence is to use and manage DNS responses (i.e.
