The SoR and reference data API
layers take the microservice calls
and pass them to the back end to
fetch the results that are either
directly in JSON or converted to
JSON from Simple Object Access
Protocol and returned through
the microservice interface to the
component assembly layer.

The midtier, presented in the paper written about
the study, was built in the IBM Montpellier lab to
run on Linux* on z Systems, co-located on the same
z Systems platform with the SoR and SoE powered
by the IBM MobileFirst* Platform. The end-toend system was built for the banking showcase
demo environment.

IBM API Connect* provides
similar functionality as the
aforementioned SoE and an
integrated environment for
creation, runtime, management
and security foundation for
APIs consumed by modern

Quantifying the
Benefits of Caching
A study conducted at the
IBM Montpellier lab measured the
benefits of midtier caching in a
banking workload based on CICS
and DB2 (see Figure 2, page 28).
IBM Rational* Performance Tester
was used to simulate 100 concurrent connections from mobile
users with a half-second think
time between each transaction.
For every user, the first transaction is a deposit followed by
six balance check transactions
to see if the deposit was reflected
in the account balance. After the
first balance check transaction,
the response is cached in the
midtier using WebSphere eXtreme
Scale and the memory object
for the stored response is invalidated after three seconds. For
this access pattern, a 30 percent
reduction in response time for the
check balance transactions was
obtained, as was 39 percent lower
three-year total cost of acquisition
(TCA). TCA accounts for hardware
and software charges, including
maintenance and support for the
combined systems of integration
and SoR tiers running on an
IBM z13*.

Sshhh...Unsecured SSH Keys
to Your IT Enterprise Left
Under the Doormat.
WHEN
Wednesday, October 5
10 PT / Noon CT / 1 ET

Stay ahead of the compliance game
with proactive and preventative
SSH Key Management.
AGENDA
Keys have proliferated the market place and present a high
security risk. Join us as we discuss SSH key exposure in the
Enterprise environment. What are they? Where are they?
How do you manage the lifecycle?
Compliance is a cornerstone issue for companies for whom
transferred data has to be audit compliant. We'll discuss
standards presented in the NISTIR 7966 document covering
SSH keys. Can you guarantee that you're compliant? Where
are your access security risks?
Learn how keys can be tracked and managed to ensure that
you close any doors that may provide access to intentional
malicious attacks or inadvertent data corruption.
