SUNTONE ARCHITECTURE METHODOLOGY A 3-DIMENSIONAL ...

Confronted with silo problems, many organizations adopt a strategy of Web-enabling
each silo independently. While achieving the short-term objective of making these
systems available over the Web, the resulting Web presence is fractured and difficult
for customers to navigate. More seriously, this approach makes it extremely difficult to
combine the functionality of various silos and create new value-added services.

For example, a company might separately Web-enable its order entry system and its
inventory system. Although this allows customers to check on product availability and
order products, it does not enable customers to check availability as part of the order
entry process, let alone suggest alternative products as substitutes for those that are
currently out of stock.
The systems architecture needs to support what might best be described as an enterprise
utility model. Like electricity through a power outlet or water through a faucet,
services need to be provided around the clock from standard access points to any
network device. These services need to bridge the silos to allow for an integrated,
customer-centric presentation of your business.
SERVICES-DRIVEN ARCHITECTURE
THE NEW FOCUS ON “NETWORK SERVICES”
The dot-com age is all about service delivery—anytime/anywhere access to any
needed service with predictable availability, reliability, performance, and security. The
SunTone Architecture Methodology focuses on how to identify, design, and deploy
network services to deliver this quality of service, within the severe time constraints
imposed by the dot-com space.
