consolidate service Explanation: Your on the right track. It means to consolidate services in the most general terms.

application service level Explanation: Your text is being increasingly obscure / badly written / content-free, but I think I understand this. Middle tier here probably refers to an architecture I used to work with which has three levels: 1 - desktop machines running the client software that connects to levels two and or three (though perhaps better only level 2) 2 - servers running application servers that communicate with the client software on level 1 and the databases on level 3 3 - database servers We actually found it a good idea to have separate machines, or at least separate virtual machines for each server, but IBM takes a different view and would like to sell a big machine, consolidating the middle level withthe database level. Well that´s the way IBM thinks ... |
