Access to MySQL on a shared web hosting with MySQL + PHP is limited to the web server running PHP. It's impossible to connect to the database through standard MySQL libraries from other servers or desktops by entering server/port/password in an application.

However, there might be hosting services that provide external access to MySQL. These services may be suitable for data hosting without web hosting functionality.

The topic of MySQL database hosting has been discussed numerous times. It is simpler and often less expensive to host your own MySQL database on digitalocean/flops/other platforms.

However, if external hosting is still desired, there are options such as SiteGround and Google Cloud SQL that offer shared hosting services with specified request limits. These services can easily be found through a quick Google search for "MySQL database hosting".

Access to MySQL from external sources can be enabled on several web hosting sites through the control panel. Additionally, SSH is offered by many hosting services, and a tunnel can be established using it to connect to MySQL externally.

For individuals or organizations that have specific requirements for external access to MySQL, there are hosting services that cater to this need. These services offer a separate hosting environment specifically designed for hosting and accessing MySQL databases externally, without the traditional web hosting functionality.

These specialized hosting solutions typically provide secure access to the MySQL database from external servers or desktops. They may include features such as dedicated database servers, secure connections using protocols like SSL, and robust access control mechanisms to ensure data security.

When considering such hosting services, it's important to assess the specific requirements of the project or application. This includes understanding the volume of data to be hosted, the expected level of traffic, and the need for scalability and performance optimization.

Security is a paramount concern when it comes to external database hosting. Ensuring that the hosting service implements strong encryption methods, access controls, and regular security updates is crucial for safeguarding sensitive data.

In addition, it's important to consider the level of support and maintenance provided by the hosting service. A reliable support system can make a significant difference in the event of any issues or technical challenges related to database hosting and accessibility.
While shared web hosting with limitations on external MySQL access is a standard practice, specialized hosting services offer valuable options for those who require external access to MySQL databases without the typical web hosting framework. By prioritizing security, scalability, and support, individuals and organizations can make informed decisions about hosting their databases in a separate, external environment.
