Shared hosting is a great choice for website owners who are looking for an affordable and user-friendly option. It's perfect for personal projects, small businesses, and even medium-sized businesses that don't need a lot of resources. As resources are shared, smaller websites that don't use as many resources can run efficiently. Shared hosting also allows you to have multiple website domains, as long as all domains are connected to your user directory.
So if you want to have separate websites for your online business, a personal blog and something else, you can easily do it on a shared server. However, if you're getting more traffic to your website or your website requires more resources, shared hosting may not be the best option. As a hosting provider, the more resources you can get, the better. You need dedicated hosting with root-level customization options or a VPS.
You need easy scalability, system stability, and trust in the underlying infrastructure. Both shared hosting and dedicated servers have their advantages. While shared hosting is a great way for startups to save money, eventually you'll want to make the switch to a dedicated server.
