When growing companies realize they need reliability help, they typically evaluate two options: hiring a fractional or embedded SRE, or engaging a managed reliability service (like a retainer). Both models solve the core problem — your team needs reliability expertise it does not have in-house — but they do so in fundamentally different ways.
Managed reliability services (retainers)
A reliability retainer provides ongoing support from a reliability partner. Cloudvorn's retainer model, for example, includes alert tuning, incident reviews, dashboard improvement, reporting, runbook updates, and advisory support on a predictable monthly basis.

Combining both
Many Cloudvorn clients use both models. They might start with a project engagement, transition to a retainer for ongoing support, and then add an embedded SRE when they enter a critical growth phase. The models are complementary, not competing.
