An organisation is choosing between Instana SaaS and a self-hosted deployment. Which factors should drive the decision?
Select an answer to reveal the explanation.
Short Explanation
You choose based on expected scale, retention requirements, security and data-residency obligations, and whether the monitored environments can reach the chosen backend. Decide all four before you install anything.
Full Explanation
The correct choice is the one that weighs expected scale, retention requirements, security and data-residency obligations, and whether the monitored environments can reach the chosen backend. Scale drives capacity, retention drives storage and compliance, security and residency requirements may rule out SaaS entirely, and network reachability determines whether agents can reach the backend at all.
The quicker-to-start option is incorrect because the deployment model determines who operates the backend and where data lives; changing it later is a migration, not a redeployment.
The storage-cost-alone option is incorrect because deferring retention until storage is exhausted forces a decision under pressure and risks data loss.
The single-test-host extrapolation option is incorrect because one test host is not representative of a production estate's telemetry volume.
For the exam, name all four drivers of the architecture decision.
