For a global social media application like TikTok, it is generally recommended to use servers distributed around the world for better user experience and performance. There are several considerations for purchasing an overseas server:

Geographical location and user distribution:

TikTok has users all over the world, so having servers in different regions can provide faster response times and more stable connections, ensuring users can quickly load and play video content.

Video traffic management:

TikTok is a video sharing platform that involves a lot of video uploading and downloading. By setting up servers around the world, better video traffic management can be achieved, reducing network congestion and latency issues.

Regional restrictions and compliance:

Different countries and regions may have specific laws and regulations and content review requirements. By deploying servers in different regions, you can better comply with local laws and regulations and provide content that meets regional requirements.

Redundancy and reliability:

Servers distributed in multiple geographical locations can provide redundant backup and failover functions to ensure that even if a server fails, the stability and availability of the application can still be maintained.

It is worth noting that purchasing and managing a server network distributed around the world requires corresponding technologies and resources, including network configuration, load balancing, data synchronization, and security management. If your application is small in scale or mainly for users in specific regions, you can consider cooperating with hosting service providers who have established a global server network and provide related management and support services.

Generally speaking, buying overseas servers is beneficial for global social media applications such as TikTok, which can provide better performance, user experience and regional compliance. However, the specific server deployment strategy should be evaluated and decided based on factors such as your application requirements, budget, and user distribution.
