MediaWiki is an extremely powerful, scalable software and a feature-rich wiki implementation that uses PHP to process and display data stored in its MySQL database. When a user submits an edit to a page, its writen to the database, but without deleting the previous versions of the page, thus allowing easy reverts in case of vandalism or spamming. MediaWiki can manage image and multimedia files, too, which are stored in the filesystem. For large wikis with lots of users, MediaWiki supports caching and can be easily coupled with Squid proxy server software.

Welcome:

If you're in a search for the top mediawiki web hosting service, most companies listed are all owned by EIG (Endurance International Group). They have been buying up companies now for years and years. Does that mean it makes no difference who you sign up with? No, because companies still offer different prices, plans, data centers locations and so on.

Data Centers: The most important thing in my opinion is what has taken place as EIG has purchased these huge companies (Bluehost, Hostgator, Justhost, Hostmonster) to name a few. Basically Bluehost's data center is so awesome Hostgator's (one of the largest hosts in the world) customers were migrated to Bluehosts data center, along with Justhost, Hostmonster and Fast domain. That really tells a huge story.

Quick Info:

Shared is an entry level plan but can handle most websites. It is a minimum requirement to have a website accessible to everyone else on the internet. If you do not have a website or are using a free service and time to upgrade, then shared is an option is for you.
Cloud is another good choice for entry level users. Not all providers offer it. With cloud your website is automatically distributed across three mirrored devices to ensure safety and redundancy so it's more reliable, faster and only costs a couple of dollars more per month over shared.
First off, Wordpress works just fine with shared or cloud plans for most people. However, if you get a lot of traffic or consume a lot of bandwidth then a Managed plan is right for you with its optimized performance and blazing fast speeds! Free premium templates and All-in-one marketing.
