What do you like best?
I used it a few years ago, and even though it was a bit more expensive than their competitors they had so many good features for its value.
I would describe it as the best hosting provider if using Wordpress or PHP.
They have lots of one-click installation programs, and you don't really need much knowledge to install any popular script.
I love unlimited aditional domains, subdomains, SQL databases, bandwidth and disk-space. What else can you ask for?
Finally, and as far as I know they provide 100% up-time guaranteed in their hosting, which is rare, but it is amazing for this price.
What do you dislike?
When talking about Virtual Private Servers, I would definitely go for other service provider. I think they should be a bit cheaper.
Let us be honest, right now if I had to hire a webpage server, I would go for a NodeJs, Django or Ruby On Rails solution.
I guess their interface could be better, it is true, you can customize lots of things, but I feel a bit lost when playing around.
Recommendations to others considering the product
Just come to DreamHost if you are hosting a PHP website. Afterwards, make sure you know what you are doing. Dreamhost is a great provider in terms of customization, you can do many things, but with great power comes great responsibility.
If you have all the requirements, you will definitely feel satisfied.
It is the best value you can find if you matter about an unlimited database and unlimited storage.
What business problems are you solving with the product? What benefits have you realized?
I had to host the typical university association webpage, so after studying all posibilities I decided to for this hosting service.
The experience was great, I remember we hosted linux images, the webpage, some other personal files, photos, and I do not remember any problem during the whole experience.
