Managed hosting simply means someone helps you run your website. I do website management.
If you are in business or occupied practising your talent you may not wish to add the time it takes to setup and update a website for yourself. I do this for you using Wordpress or Joomla on secure host using your domain name.
I offer hosting using the InMotion systems but can use any service you wish.
I limit my services to Wordpress and Joomla as these are the most popular Open Source products Web Content Management Systems (CMS) available today and are very well supported around the world 24 hours a day. This means if (OK, when) a hack is found the patch is often found immediately somewhere on the planet a fix is made and published and your site spends the least time insecure. This is a feature of the open source world where the program is popular, they can be superior to commercial products because their support base is so much larger.
