Description: Chaos Monkey is an open source technology that was developed by Netflix engineers to test the resiliency and recoverability of their Amazon Web Services (AWS). This technology simulates failures of instances of services running within Auto Scaling Groups (ASG) by shutting down one or more of the virtual machines. This technology has a configurable schedule that allows simulated failures to occur at times when they can be closely monitored. In this way, it is possible to prepare for major unexpected errors rather than waiting for a catastrophe to strike and seeing how well it can be managed.

This technology requires a MySQL-compatible database. The database is used as a backend to record a daily termination schedule and to enforce a minimum time between terminations.

The TRM decisions in this entry only apply to technologies and versions owned, operated, managed, patched, and version-controlled by VA. This includes technologies deployed as software installations on VMs within VA-controlled cloud environments (e.g. VA Enterprise Cloud (VAEC)). Cloud services provided by the VAEC, which are listed in the VAEC Service Catalog, and those controlled and managed by an external Cloud Service Provider (i.e. SaaS) are not in the purview of the TRM. For more information on the use of cloud services and cloud-based products within VA, including VA private clouds, please see the Enterprise Cloud Solutions Office (ECSO) Portal at: https://vaww.portal.va.gov/sites/ECS/SitePages/Home.aspx
Technology/Standard Usage Requirements: Users must ensure their use of this technology/standard is consistent with VA policies and standards, including, but not limited to, VA Handbooks 6102 and 6500; VA Directives 6004, 6513, and 6517; and National Institute of Standards and Technology (NIST) standards, including Federal Information Processing Standards (FIPS). Users must ensure sensitive data is properly protected in compliance with all VA regulations. Prior to use of this technology, users should check with their supervisor, Information Security Officer (ISO), Facility Chief Information Officer (CIO), or local Office of Information and Technology (OI&T) representative to ensure that all actions are consistent with current VA policies and procedures prior to implementation.
Section 508 Information: This technology has not been assessed by the Section 508 Office. The Implementer of this technology has the responsibility to ensure the version deployed is 508-compliant. Section 508 compliance may be reviewed by the Section 508 Office and appropriate remedial action required if necessary. For additional information or assistance regarding Section 508, please contact the Section 508 Office at Section508@va.gov.
