Site reliability engineering (SRE)

Nobody praises software for staying up; everybody remembers when it went down. SRE makes reliability deliberate: decide how reliable you need to be, measure it, and build the alerting, incident practice and resilience testing to defend it.

Service details

At a glance

  • SLOs and error budgets that make reliability measurable
  • Alerting tuned for signal, not noise
  • Incident response and on-call practice
  • Resilience tested deliberately, chaos experiments included

Decide how reliable you need to be

One hundred percent is not a target; it is a way to spend infinite money. SLOs and error budgets put a number on the reliability the business needs, and that changes the conversation - suddenly there is a rational way to weigh shipping features against paying down risk, and “is it reliable enough?” has an answer.

Alerts people believe

Alert fatigue is its own outage: when everything pages, nothing does. We tune alerting until a page means something real, wire in the observability to understand problems before users feel them, and help your team practise incidents so the real ones run calmer.

  • Observability that shows trouble coming
  • Pages that mean something, so people respond
  • Blameless reviews that make each failure useful

Prove it, don’t assume it

Where the stakes justify it, we test resilience deliberately - chaos experiments that surface weaknesses in the calm of a working day instead of the noise of a real outage. Every failure, staged or real, feeds back into a system that gets harder to knock over.

Frequently asked questions

What’s the difference between SRE and DevOps?
DevOps is about how software gets built and shipped; SRE is about how reliably it runs once live. They overlap, and we work on both - but this service is for the running half.
What are SLOs and error budgets?
An SLO is a measurable reliability target; the error budget is how much failure that target allows. Together they turn reliability from an aspiration into something you can manage.
Our alerts are noisy and everyone ignores them - can you help?
Yes - noisy alerting is one of the most common and most fixable problems we see. Tuning it restores trust, and trusted pages get answered quickly.
Do we need chaos testing?
Not everyone does. But deliberately breaking things is the quickest way to find what a real outage would otherwise find for you - where reliability truly matters, it earns its place.
