When it comes to web hosting, you will find that dedicated servers tend to be the best option which is why they appear to be relatively more expensive compared to other hosting categories. The reason that dedicated servers are better according to Startups Genius is because every single one of the available resources that you pay for would be exclusive to you and no one else would be using them.
If you go for shared hosting for example, you will be sharing important resources such as the CPU and memory with a number of different users some of whom may be too harsh on the server causing outages the impact of which would be felt by everyone else on the same server.
To prevent such issues from causing you damages, you should be avoiding shared hosting accounts if your website is important to you. There are many different types of dedicated servers around which you will have to choose from as not every single package of a dedicated server offered by various hosting companies would be exactly the same.
They will all vary a great deal making it important for you to understand how exactly each of these services compare. If you know your requirements, it would be easier for you to decide what hosting package to go for.
