LISA VirtualizeTM
Eliminate dependencies on downstream systems for unconstrained development and testing
LISA Virtualize can break through the delays, costs and risks imposed by dependent IT resources that are unavailable or inaccessible for development and testing. LISA Virtualize eliminates system dependency constraints by "virtualizing," or capturing and modeling, the target system's dynamic behavior, data and performance so that it reacts and responds the same as the live system. Using LISA Virtualize, concurrent test and development teams have 24/7 access to realistic production environments to shorten their release cycles. Costs for test labs, responders, and stubs are dramatically reduced, and quality is improved by testing more scenarios faster and earlier in the lifecycle.
The Challenge: Unavailable Services Constrain Agility and Productivity
System dependencies and constraints can severely limit your development and testing efforts, especially in complex, interdependent environments. Downstream components may be unavailable, poor performing, or unusable. In addition, the high costs of setting up complete test labs, mockups and stubs, combined with contention for shared resources, can limit the scope of testing, significantly compromising quality and increasing risk. Challenges include:
- Unavailable/inaccessible: Systems may be constrained due to production schedule, security restrictions, contention between teams, or the service end points may not have been built yet.
Poor performing: Systems or mockups that are available may not provide the behavior and performance needed. - Data Volatility and Inconsistency: Configuring test data scenarios across distributed systems can be extremely time consuming or cost prohibitive
- Impractical for hardware-based virtualization: Systems are either too difficult (mainframes) or distributed (remote third-party) to replicate via hardware or server-based virtualization approaches
- Costly 3rd party access fees: Reliance on cloud-based or other external services can result in costly per-use fees when testing
As a result, development and delivery teams often sacrifice software quality and increase risk by reducing their testing effort, or they resort to costly and time-consuming provisioning and maintenance of their own physical test environments.
The Solution: LISA Virtual Service Environments
LISA Virtualize removes dependency constraints on development and delivery teams, so they can deliver software faster, with less risk and lower costs. LISA automatically captures and creates realistic virtual models of dependent systems, so that live systems are no longer needed for development or testing purposes. The virtual models generated by LISA are dynamic - not static in behavior, and can accurately simulate complete stateful transactions and handle key parameters intelligently.
LISA Virtualize Features:
- Capture and analyze the live traffic between systems to rapidly create a robust model of the target system's dynamic behavior, data and performance.
- Simulate 3rd party services that are deployed outside the local implementation, providing realistic responses back to the developer or tester.
- Automated test staging including setup/teardown, data configuration and other costly and time-consuming efforts.
- Unconstrained performance and load testing, by providing a readily available test target that can be adjusted to the performance and scale characteristics desired by the testing team.
- A management dashboard to easily customize virtual models for multiple teams, and manage and schedule when and how virtual services are run.
