Photo hosting providers usually have free and paid plans, so you don’t even need to pay to use them. Unfortunately, your clients will be paying the price for it by seeing ads when browsing your portfolio. It might be okay for a beginner but does not look very professional. If you get a paid plan, you will be able to use the provider's interface only without the ability to install something else.
Cloud VPS is a type of hosting where multiple companies use isolated instances on the same host or parent server. This is perhaps the most common type of VPS hosting — when you hear someone talk about VPS, it’s most likely Cloud VPS. As you probably guessed based on the word “cloud,” another benefit is that you can access your Cloud VPS environments from anywhere.
Essentially, here’s the criteria I would use to judge things – if your site is made up of primarily static, HTML-based content, then you probably don’t need a VPS package. However, if you have a large amount of files stored, multiple sites, dynamic content, and the possibility of major traffic from time to time, then you might consider upgrading to a VPS. It’s a powerful package that allows you to do more than you could with a shared hosting plan, but requires less investment than a dedicated server.
As you can see, a VPS can be the perfect middle ground for many – enough flexibility and resources for those who need more access or control than on a shared server but without the cost of a dedicated server. If you need root access, you can’t get that on a shared server, but you can get it on a VPS. If your site experiences unpredictable swings memory usage, and your host provides it, then the presence of burstable memory will be attractive. And, if you’re a fan of customization, then the fact that you can customize server-level software such as PHP, MySQL, and Apache will perk your interest. In short, choosing a VPS will allow you to have many of the same characteristics of a dedicated server but in a more affordable and manageable package.
