AppDynamics vs Datadog
Same-cluster observability peer comparison. Choose AppDynamics when Cisco vCPU-priced APM (Premium $33, not $6 infra) is the job — not Datadog host modules by default. Choose Datadog when observability — infrastructure, APM, and logs — is the primary job and you can model module/consumption TCO. Overall: AppDynamics 7.9 vs Datadog 8.6. Not hands-on lab tested; confirm live pricing and packaging. Compare published pricing, ITSM, observability, source control, hosting, web data, security, and integrations.
AppDynamics
Cisco APM / observability — Infrastructure from ~$6/vCPU/mo; Premium (infra+apps) from $33/vCPU/mo annual; Enterprise $50/vCPU; often Cisco EA quote. Does not outrank Datadog 8.6.
Best for
- • Cisco-aligned estates that will model vCPU Premium $33 (not $6 infra-only) as APM TCO
- • APM buyers comparing AppDynamics to Dynatrace DPS and Datadog modules
- • Teams already in a Cisco EA who will not self-serve Datadog tiles
Starting from $33.00/user/mo
