VPS: Virtual Private Server
This is a dedicated instance within a server. Unlike shared philippines country code mobile number hosting, VPS have dedicated hardware resources, operating system and IPs, so if you buy a configuration such as: 4GB RAM, 6 vCPU and 500GB SSD, the resources will be entirely dedicated to the project. You can also note that VPS are usually sold with a monthly fee, while shared ones have an annual payment (also given the less expensive cost).
Personally, I consider VPS servers the best choice for e-commerce projects or those with high traffic.
Advantages:
Monthly payment;
Custom configuration;
Dedicated resources;
Possibility to scale the project.
Disadvantages:
Dedicated technical support;
Hosting management panel not included, but can be installed separately with a license;

Regarding this, there is no dedicated guide, what we can recommend is to turn to professionals who have already had experience in the field of web performance. In this way they will be able to direct you to the right IT company.
