How
do
APIs
help
the
EA
achieve
their
goals?
§ Bridge
legacy
architectures
(SOA/ESB)
with
emerging
technologies
and
digital
iniRaRves
§ Allow
digital
iniRaRves
to
access
data
faster,
and
reuse
of
exisRng
systems
without
complex
hardwired
coding
§ Requires
a
4
phased
approach
that
we
call
API360:
– Alignment
with
Business
Strategy
– Designing
APIs
to
Meet
Your
Customer
and
Developer

– ArchitecRng
sustainable

– SelecRng
