4.3. Managing groups, instances and products
Under Groups menu, groups of instances are listed and can be managed. Every instance can be member of one group exclusively.
No instance managed
If there is no instance managed in any of the groups, then a 
notification appears at the top of the page:
Central Management can manage several instances. Instances are grouped and groups have subgroups called products. An instance is automatically added to the product of its type. If the product does not exist at the time of adding the instance, then the appropriate product is automatically added to the group.
Product example
For example, if a MetaDefender Core instance is added to a group that hasn't got a member of that type yet, then the Core product (subgroup) will be added to the group. If the instance is not the first of that type in the group, it will simply be added to the appropriate product.
Instance configuration stored with product
Configuration of instances is stored on the product level. For example: configuration of all MetaDefender Core instances of a certain group is stored with the Core product. It means that if we want to get rid of the centrally stored configuration, then we first need to remove all instances from the Core product, then the Core product must also be removed.
