Szia János! 🙂
Let me reply in English as long as the title has been formulated in that language...
First of all, let's separate DT vs DD and DT vs OpenSource!
DataDog development is near head-to-head with DT, features like AI based RCA, DORA metrics, AppSec, AI/LLM monitoring sounds very similar to capabilities of Dynatrace. But Dynatrace made them available first...
Datadog Docs - if you have a look at the topics, they look very familiar to me what we have in Dynatrace.
From AI prospective, the Dynatrace Davis AI corresponds to Datadog Watchdog. Datadog Watchdog™
Davis Copilot is similar to Bits AI Bits AI... Etc.
The key element here is to make comparison to the SaaS solution (DD is available ONLY in SaaS) because managed is far behind in feature development...
OpenSource can be effective if:
- you have Platform Engineering with built-in monitoring (MONACO)
- No need to cooperate with other departments (eg.: you are a small development company)
You are right, the complexity makes the game much harder. When you need to correlate different tiers and silos, collect logs and traces and maybe integration with CI/CD is also required.
The effort needed to setup OpenSource products and keeping up the consistency between the systems is much higher than using DT. Overall, we can easily make a statement: what you gain on license cost, you lose it on operational and payroll costs. You can also outsource it, can be more effective but not really cheaper...
TCO is your friend...
