A shared hosting service may be appropriate throughout the early phases of the life of your online venture, since there is no sign of how successful the project will be. On a shared hosting account, your website may have been working alright for a short period of time. Downtime may have been the source of annoyance to you for some time though during your usage of the shared web hosting service. Unauthorized access to your account may also have been a matter of concern to you, which kept you worried given that you were not content with the security on your shared web hosting account. All that may have been acceptable for a certain period of time, when you were not that serious to see your venture become a true success, however it seems not to be true anymore. Secondly, as the number of visitors of your website multiplies over time, other hosting options may need to be considered.
One alternative may be to consider upgrading to a VPS hosting package. This may be fine for some time but as your website continues to grow in size reaching a couple hundred pages, you may look forward to receive millions of visitors in a month depending on how vibrant your web promotion approach is. This is precisely the point where you may feel that the demanding needs of your online venture can only be supported by a higher-level hosting package, i.e. a dedicated web hosting server. So, you start seriously thinking about migrating to a dedicated web hosting package, which may give you the kind of stability, security, and functionality that you currently require for your project.
