Email backbone : ウィキペディア英語版 | Email backbone
An email backbone is typically the middleware of an email infrastructure that manages SMTP-based applications, internal and external email message routing, and policy management and enforcement. The email backbone is normally the portion of the email infrastructure that "sits between" the gateway DMZ layer and the “email groupware system” layer of the messaging infrastructure, such as Microsoft Exchange or Lotus Notes/Domino. The email backbone is sometimes referred to as the messaging fabric or a messaging infrastructure layer〔http://www.irg-intl.com/whitepaper/2010-Messaging-Fabric.html〕 ==Email backbone infrastructure and cloud computing==
Many businesses are either considering or are actively migrating to cloud-based email because it can offer a number of important benefits. These benefits may include lower cost of ownership, more predictable costs, the shift from a capital expenditure (CAPEX) to an operational cost (OPEX) model, and less demand for internal IT resources. The typical email infrastructure functions that are moved to the cloud include the email filtering layer for spam and virus protection, message archiving and the "email groupware system" mailboxes. The email backbone layer typically stays on on-premises.
