I'm looking for a solution that incorporates most or all of the following:
Patch Management, Server event viewing/tracking, AD change management, ticketing and internal/external kb, remote access - ability to shadow user sessions or create new ones, imaging, and inventory.
Our environments contains Windows Servers and ESXi Hosts (We're not completely virtual, but we're moving that direction). Various Cisco and Linksys switches and firewalls.
This is a tall order, and I don't know if it can be done on a reasonable budget.
I've looked and found some questions on SF that deal with some of this:
Active Directory management tools for medium sized forest (less than 1000 users)
Are there any tools to do change management with Active Directory / Group Policy?
What is a good patch/update management server?
What I'm ideally looking for is a reasonably cheap solution that integrates the features into a central interface. We're a non-profit, so money is a limiting factor (the cheaper, the better; but we have a max of $15k). What we are trying to avoid is having to deal with multiple vendors, while maintaining scalability (we're creating more sites that we'll have to manage).
Is this possible, or will we have to cobble together something to make it work for us?
Edit: Even if this is a pipe dream for us, is there anyone out there offering this type of solution at all?
