I need to do a powerpoint that includes oursourcing our DR or insourcing by investing in POD for high availability.

I know the cost difference between both are dramatic and wide which is the driving force that will eventually lead down to POD's.

I need a resource to help me put this powerpoint together.

Virtualisation is one technology we are also looking to include in this decision.

They are two different concepts that overlap not unlike a Venn diagram.

I mean it's basically redundancy(the five 9's) vs  the mean time to recover.

Here's an Oracle article on it that might be of some use,it's their propaganda,but it does a good job of contrasting the two.

hi there

I think when you say DR normally that is a cheaper solution as there is no plan for future growth.

HA always needs to plan for future growth and share the load of the running business.

I think in your case we need some more information like
is the a business critical issue if some servers/roles does not work.
Is it a billing company "SQL" Oracle etc. DB warehouse.

or you could split some of the server/roles. Some into HA = Business critical 24/7
some on DR less critical = HR or file servers. Backups.
