Service directory and fault injection management systems and methods

A method, comprising:

• creating a service directory including data indicative of dependencies of services of a system based on developer input,
• wherein instances of a first service are dependent upon instances of a second service and wherein the dependency relationship between the first service and the second service is based at least on a dynamic naming service (DNS) log and is stored in a service directory;
• updating the service directory to include data indicative of additional dependencies of services of the system based on a domain name system (DNS) log updated by a DNS server;
• based on data in the service directory, determining faults to inject into the system;
• injecting the faults into the system;
• and
• monitoring the system for failures created by the injection of the faults.

A system, comprising:

• one or more processors;
• and
• memory including a program that, when executed by the one or more processors, performs functions comprising:
• creating a service directory including data indicative of dependencies of services of a system based on developer input, wherein instances of a first service are dependent upon instances of a second service, and wherein the dependency relationship between the first service and the second service is based at least on a dynamic naming service (DNS) log and is stored in a service directory;
• updating the service directory to include data indicative of additional dependencies of services of the system based on a domain name system (DNS) log updated by a DNS server;
• based on data in the service directory, determining faults to inject into the system;
• injecting the faults into the system;
• and
• monitoring the system for failures created by the injection of the faults.
