DevOps is…
A set of principles and values that
facilitate collaboration across
disciplines to…
1. Enable rapid evolution of
deployed business services
2. Reduce risk, decrease cost, and
improve quality across the
portfolio

Virtual Services
Heterogeneous Environments
System dependencies are a key challenge in setting
up test environments:
Test Virtualization enables to create “virtual
services”:
Unavailable/inaccessible: Testing is constrained due
to production schedules, security restrictions,
contention between teams, or because they are still
under development
oVirtual Services simulate the behavior of an
entire application or system during testing
oVirtual Services can run on commodity
hardware, private cloud, public cloud
oEach developer, tester can easily have their
own test environment
oDeveloper and testers continue to use their
testing tools (Manual, Web performance, UI
test automation)
Costly 3rd party access fees: Developing or testing
against Cloud-based or other shared services can
result in costly usage fees
Impractical hardware-based virtualization: Systems
are either too difficult (mainframes) or remote (thirdparty services) to replicate via traditional hardwarebased virtualization approaches

IBM Rational Test Virtualization Solution
Test Virtualization is an enabler for
continuous Integration Testing
Services, applications, systems are
introduced into the continuous integration
cycle in a prioritized, controlled fashion.

Avoid time spent installing and configuring software just to discover
basic build issues
Smoke tests can be integrated as part of the continuous integration
process through deployment automation and test virtualization
Smoke test results are made available to the entire team to shorten
resolution

• PureApplication Systems
5. Infrastructure as Code
package "apache2" do
package_name node['apache']['package']
end
service "apache2" do
case node['platform_family']
when "rhel", "fedora", "suse"
service_name "httpd"
# If restarted/reloaded too quickly httpd has a habit of failing.
# This may happen with multiple recipes notifying apache to restart - like
# during the initial bootstrap.
restart_command "/sbin/service httpd restart && sleep 1"
reload_command "/sbin/service httpd reload && sleep 1"
Tools:
• UCD
• IBM SmartCloud Provisioning, IBM Workload
