“We have failover.” That sounds reassuring. But when real failure hits… many systems still go down — hard. Why? Because failover is easy to configure — but extremely hard to make reliable at global scale. Here are the most common ways failover fails in production: RDS Multi-AZ enabled Kubernetes failover configured Looks good on paper. Reality: Takes minutes instead of seconds Gets stuc

If your team works with geospatial data, sooner or later you need a place where maps, layers, users, and edits live together. There are many capable SaaS platforms and proprietary solutions you can deploy on your own infrastructure, but there is another path: self-hosting an open-source Web GIS server. In this tutorial, we will deploy NextGIS Web on a low-cost VPS using Docker, and then configure
