If you have a significant amount of cash to spend on dedicated servers, and your company absolutely needs this, and you've the necessary technical knowledge to establish and maintain the website and backend services, you may choose a dedicated server.
However, the majority users are either new to Web hosting or don't need the capabilities which a dedicated server offers. Shared hosting services aren't only for casual bloggers or personal site owners. They are capable of handling over 100,000 monthly visitors which is roughly more than 3000 people per day.
This makes it an ideal solution for companies with less than 25 employees. The majority of them don't want to manage any tasks that maintain servers or keep track of backend operations. They would like to present their products or services all over the globe and generate maximum profits in the shortest time possible.
This is why the shared hosting option could be the best choice since the business owner is only required to manage and maintain the website, and the hosting service provider will handle all other aspects. The number of visitors will depend on the strategies for marketing and advertising that the company has in place and is likely to be lower in the beginning.
If the number of visits is in over what the hosting company allows, they'll provide you with the option to easily switch to a higher plan that has more resources. If your website is unable to earn enough money or traffic, you could end the service at any time with just a few clicks.
