DreamHost offers several different types of hosting plans running on the Ubuntu operating system. Most sites work well on the basic Shared hosting plan, however if your site is getting a large amount of traffic or if you need to make customizations not available to shared users, you may need to upgrade to a VPS, Dedicated, or DreamPress plan.
You can find further details at DreamHost Hosting which describes the various options available to you as a DreamHost customer.
NOTE: There is currently not an email-only hosting plan available at DreamHost. If you need email, you must add a website hosting plan first.
On a shared server, you 'share' server space with other customers. Though no other customer has access to your files, you and the other customers share the resources of the server. This means that if another website on the same server is receiving a large amount of traffic and using a lot of CPU resources, it's possible that your site may run slower as a result.
While DreamHost works hard to make sure all sites on a shared server never disrupt other sites, this is always a possibility due to the nature of shared hosting.
Shared hosting is perfect for blogs, portfolios, personal/business sites, and database-driven sites. Visit the following page for further information:
Shared hosting plans offer a free Non-Profit plan for qualifying non-profit, charitable organizations registered in the United States. View the following article for further information:

The DreamHost Virtual Private Server (VPS) is a premium hosting solution that runs on Solid State Drives (SSDs.) It is available as an add-on to an existing DreamHost plan or a standalone service.
DreamHost VPSs use Linux-VServer to create a "virtual machine" that protects a user's CPU and RAM resources from other users on the same physical machine. This is accomplished by kernel level isolation which allows the server to run multiple virtual units at once. Those units are sufficiently isolated to guarantee the required security, but utilize available resources efficiently, as they run on the same kernel.
On a shared server, resources are shared by other users. On a VPS, these resources are more isolated which improves performance and helps to maintain stability.
You also have the ability to control how much RAM your server uses. On a shared plan, this is limited to a specific amount; but on a VPS, you get to select how much RAM your server can use.
What can I host on a private server?
A VPS is ideal for websites that require more resources than a shared server can provide, yet do not need the full power of a Dedicated server. It's ideal for businesses, ecommerce, designers, and developers.

A Dedicated server is a server that only contains your websites and data on it. No other customers share any resources or have any access to it, as it's "dedicated" to you and your data.
You have full root access to customize it anyway you wish, but please note that DreamHost support cannot assist if any errors occur as a result of a customization.
Another feature is that your MySQL server is on the same Dedicated server allowing faster access, unlike with all other hosting plans where your MySQL databases are on a separate database server.

What can I host on a Dedicated server?
Dedicated servers are Fully-managed business-class servers. They are perfect for resource-heavy apps and giant websites.

DreamPress is DreamHost's Managed WordPress hosting. It's a scalable service that allows users to manage their WordPress sites with simple pricing, added benefits of server robustness, caching, and memory.
One DreamPress plan is configured for a single domain. If you want multiple domains on DreamPress, they must each have their own separate DreamPress hosting plan activated.

Apache and Nginx
If you have upgraded to a VPS or Dedicated server, you have the option to run Nginx as your web server. Shared and DreamPress hosting must use Apache. View the following article for a detailed comparison:

Secure hosting is not a specific plan, it's a service you can add on to any plan. View the following links for details:
DreamHost does not offer an email-only hosting plan. You must purchase either a Shared, VPS, or Dedicated hosting plan which includes email service. DreamCompute only plans do not include email hosting.
With any Shared or VPS hosting plan, you also have free access to a shared MySQL server. This Shared MySQL server can store all of your databases for all of your websites. Since it's a shared server, resources are 'shared' with other customer in the same way as a shared web server mentioned above.
If you need more database resources than the Shared MySQL server can offer, you can purchase a private MySQL server.
If you choose to purchase this plan, all of your databases will be moved to the private MySQL server. It's not possible to split databases across Shared and private MySQL servers.
