What is Site Reliability Engineering?
Site Reliability Engineering is the practice of running production systems with engineering rigour instead of heroics. You agree measurable reliability targets (SLOs), instrument services so you can see them objectively, automate the operational work that humans get wrong at 3 a.m., and treat every incident as input to a blameless postmortem that makes the system stronger. For regulated London businesses there's a second dividend: the same discipline that improves uptime — versioned changes, recorded approvals, tested recovery — is precisely what auditors want to see. Our site reliability engineering practice embeds senior SREs into your team to build all of it without stalling delivery.
Why SRE Matters for London & UK Businesses
In London, downtime is rarely just a technical event — it's a regulatory conversation for fintechs, lost baskets for retailers, and a clinical-safety question for healthtech. SRE turns reliability into something you can promise, evidence, and improve quarter on quarter, with the audit trail generated as a side effect of doing the work properly.
Higher uptime & SLO adherence
Reliability targets agreed with the business, measured continuously, and defended with error budgets — 99.9%+ objectives you can put in front of a regulator or a board.
Faster incident response
Practised incident command with clear severities and communication plans — MTTR falls, and stakeholder updates go out while the fix is underway, not after.
Lower toil via automation
Terraform and GitOps replace hand-made changes with reviewed, reversible ones — fewer outages, and every change carries its own audit evidence.
Predictable scaling & costs
Capacity planned from real telemetry ahead of sales events and product launches, then trimmed back after — performance and spend managed as one discipline.

SLOs, SLIs & error budgets
We define SLIs from the user's perspective — payment authorisation success, checkout latency, appointment-booking availability — then agree SLOs with both engineering and the business. Error budget policy formalises the trade-off: releases flow freely while the budget holds, and stability work takes priority when it burns. For regulated firms, the SLO report doubles as board-ready and reviewer-ready reliability evidence.
Observability engineering
Unified metrics, logs, and traces across Prometheus, Grafana, and New Relic, delivered through our monitoring and observability services. Dashboards map to SLOs and customer journeys rather than server internals, and alerting is rebuilt around burn rates — so the pager means something, and quiet nights are actually quiet.
Incident response & on-call (24×7)
Severity definitions, escalation paths, and communication templates established up front, then staffed round the clock via our 24×7 DevOps support rotation. Your London team keeps GMT/BST context and daytime primary if you want it; we hold the night watch. Every incident produces a blameless postmortem with tracked actions — and a timeline fit for regulatory reporting when that matters.
Kubernetes & infrastructure reliability
Production-hardened EKS in eu-west-2: multi-AZ topologies, pod disruption budgets, tested failover for databases and queues, and zero-downtime upgrade runbooks. We pay equal attention to the foundations — DNS, TLS, load balancing, backup restores that have actually been rehearsed — because that's where quiet failures hide.
Toil reduction & automation
We hunt down the manual work in your operations — certificate renewals, environment builds, access provisioning, DR drills — and automate it with Terraform modules and GitOps pipelines. In FCA-regulated environments this is doubly valuable: automated changes are consistent, reversible, and self-documenting, which turns audit preparation from a scramble into a query.
Capacity planning & performance tuning
Load tests modelled on your real traffic — Black Friday curves for retail, market-open bursts for fintech — with autoscaling proven against them before the day arrives. Profiling finds the slow queries and chatty services early, and the same data drives cost tuning: right-sized nodes, storage matched to access patterns, and no idle capacity padding the bill.
