market, keeping up with, if not
surpassing, their competitors
in new services, and leveraging
years of past development, all of
which can benefit the bottom line.
Enterprise developers are
often cognizant of this, knowing
how their applications can be
leveraged to meet the demands
of a faster digital economy.
They recognize, for example,
that some of their applications,
which may have been in service
for years, are monolithic and
can benefit from re-architecting
that allows them to follow more
modern development paradigms.
"Organizations that have
developer support and executive
buy-in make the transformation
the fastest," Radcliffe says.
"Even when developers aren't
starting the push, executives

can. They can find a team that's
the most open to change and
then give them permission to try
something different. Either way,
everyone from the C-suite to the IT
department has to be committed to
the overall goals if modernization
is going to be successful."
Modernization shouldn't take
place in individual development
silos, however. If this happens,
businesses may not achieve the
goals they've set for themselves,
thus dampening initial
expectations. Employing DevOps
lessens siloed development,
improves agility and reduces the
time needed to address feedback,
all of which allow companies
to respond to the market faster
while building engaging user
experiences. They can also
enjoy a startup-like culture that

Quick Takes on Application Modernization
* Modernized applications should expose APIs and microservices
* Standard DevOps practices such as automated testing, continuous
delivery and integration should be leveraged
* The larger API economy allows developers to monetize APIs by
allowing third-party applications to adopt them
* Developers or recent college graduates who have experience
with different languages or solutions can be invaluable to
modernization efforts
* Modernization offers quicker time to market by leveraging years
of past development
* DevOps minimizes siloed development, improves agility and reduces
the time needed to address feedback
* Designing and optimizing services so stakeholders understand what
services are capable of allows for better planning and future-proofing
of systems
* Designing services involves understanding how services can grow
to deal with specific workloads as business needs change
* Service should be flexible enough to, if needed, accommodate
future scaling

brings business, development
and operations together. If this
is successful, modernization
initiatives are more likely to
receive further, long-term funding.
"Although this isn't going to
be completed in a quarter or
maybe even a year, you're getting
value all along the way-no
matter how long it may take. This
should be looked at as an almost
open-ended, continual process
and budgeted with that in mind,"
Radcliffe says.

Workload Scalability
Despite best efforts, businesses
can't anticipate all of the
different ways they may
change in the future and what
affect that's going to have
on their systems. Designing
and optimizing services so
stakeholders understand what
services can and cannot offer
allows for planning, as well as
future-proofing systems.
If businesses are using
large-scale systems, they're going to
scale one way. If they're using the
cloud, they may scale another way.
The key to designing services is
understanding how they can grow
to deal with specific workloads as
business needs change.
"You need to be aware of what
you're dealing with. Just because
you made a modular component
doesn't necessarily mean it's
designed to scale," Radcliffe
remarks. "What more experienced
developers bring to the table
are thoughts about scalability,
reliability and nonfunctional
characteristics some younger
developers might not first
consider. That partnership
involves understanding that,
yes, that's really nice, but when
a million transactions need to
hit this thing in a second, you
can't read that whole table into
memory because, well, that's just
