Depends on what kind of web hosting service you are looking for (like Shared Hosting, VPS Hosting, Dedicated Server Hosting, Cloud Hosting etc). If you are on a low budget and can only spend like $5 to $10 a month, then Shared Hosting is your best bet. But please note that Shared Hosting is only good for low traffic websites (like 25 to 50 concurrent visitors across all your websites). For a list of some of the most reliable Shared Hosting providers, please visit Top Shared Web Hosting Companies and choose a reliable Shared web host.
And if you can spend like $20 to $50 or so a month, then you can go for a VPS which gives you more resources than a Shared Hosting account. With a VPS you would get dedicated server functionality without the expense.

If you can manage your own Cloud Server, then you can go for a Cloud Server which gives you better system resources than a Shared Hosting account. But please note that most of the Cloud Hosting services are unmanaged, you need to have developer skills to manage your servers. For a list of some of the most reliable Cloud Hosting providers, please visit Best Cloud Server web hosting providers and choose a reliable Cloud Host.
And if you can spend like $100 to $200 and more a month on hosting, then you can go for a dedicated server right away. A dedicated server will give you more system resources and total control.
