What managed SRE means
Site reliability engineering applies software engineering to operations: reliability targets agreed with the business, automation instead of manual work, and learning from every incident. A managed SRE service provides the team that does this for you, working inside your environment and to your standards, and accountable for agreed reliability outcomes rather than hours.
What a good managed SRE service includes
- Service-level objectives (SLOs). Reliability targets for each critical service, agreed with product and business owners, with error budgets that balance reliability against the pace of change.
- Observability. Metrics, logs and traces that show how services behave from the customer's point of view, with alerts that point to real problems rather than noise.
- Incident response. A clear on-call rota, runbooks for known failure modes, defined roles during incidents and communication to stakeholders while they happen.
- Post-incident reviews. Blameless reviews with actions that are tracked to completion, so the same failure does not repeat.
- Toil reduction. Steady automation of repetitive operational work, freeing time for improvements.
- Capacity and cost. Planning for growth and peak demand, with cloud spend kept visible and governed through FinOps practice.
- Release safety. Progressive rollouts, automated rollback and change controls suited to regulated environments.
How it differs from traditional managed services
Traditional operations contracts usually measure activity: tickets closed, response times, uptime of individual servers. Managed SRE measures outcomes users experience: whether critical services meet their SLOs, how quickly incidents are detected and resolved, and whether the same incidents keep returning. It also expects the team to reduce the work over time through engineering, not simply to absorb it.
How to judge a provider
- Do they start with SLOs? A provider who cannot explain how reliability targets will be agreed and measured is offering monitoring, not SRE.
- Who leads the team? Look for a named, senior SRE lead with experience of comparable platforms and regulated environments.
- How do they handle incidents? Ask to see a sample runbook and a post-incident review.
- What will they automate? A good provider commits to reducing toil and shows the backlog.
- How will you see progress? Expect a monthly service review against SLOs and a quarterly review of maturity and cost.
The first 90 days
- Days 1-30: map critical services and dependencies, review current monitoring and incident history, and agree initial SLOs.
- Days 31-60: build dashboards and alerting against the SLOs, write runbooks for the most common incidents and set up the on-call rota.
- Days 61-90: run the first monthly service review, start the toil-reduction backlog and agree targets for the next quarter.
When managed SRE makes sense
- Critical, customer-facing services with no agreed reliability targets.
- Engineers regularly pulled away from product work by incidents.
- Reliability knowledge that sits with a few people rather than in runbooks.
- Rising cloud costs with no clear ownership.
