Based on your needs, you might consider which location suits you, or if you need multiple servers in different geographic locations for redundancy and backup.
Local availability zones
As an extra precaution, we can place your servers in different Availability Zones within the same data center. E.g. if one instance fails in one availability zone, another can be designed to take over the task. Benefit; Low latency via Private LAN.
Remote availability zones
Multiple geographic locations offers options for increased redundancy and safety. Through remote availability zones you will have options for back up and security. If your server is unavailable in one country, the server in the other country takes over, making sure your data is always available.
