What is Site Reliability Engineering (SRE)?
Site Reliability Engineering (SRE) is a discipline — originally developed at Google — that applies software engineering principles to IT operations. Instead of treating operations as a manual, reactive task, SRE teams use automation, observability, and defined Service Level Objectives (SLOs) to build and run production systems that are reliable, scalable, and efficient.
At SquareOps, our SRE team operates as an extension of your engineering organization. We handle 24/7 monitoring, incident response, infrastructure automation, capacity planning, and cost optimization — so your developers can focus on building product instead of fighting fires. Whether you're running on AWS, Azure, or GCP, our SRE practices ensure your systems meet their reliability targets.
Need to build your cloud foundation first? Start with an AWS consulting engagement for architecture design, or our AWS DevOps services to set up CI/CD pipelines and automation. SRE is the operational layer that keeps everything running once it's built.
SRE Services We Provide
End-to-end site reliability engineering — from monitoring setup to 24/7 on-call operations.
24/7 Monitoring & Incident Response
Round-the-clock infrastructure monitoring with automated alerting, on-call rotations, and SLA-backed incident response times. P1 response in under 15 minutes.
Infrastructure Automation
Eliminate manual operations with Terraform, Ansible, and custom automation. Every change is version-controlled, tested, and repeatable — zero click-ops.
SLO/SLI Management
Define, measure, and track Service Level Objectives and Indicators. Error budget policies that balance reliability with deployment velocity.
Security Operations
Proactive security patching, vulnerability scanning, compliance monitoring, and firewall management. SOC 2, HIPAA, and PCI-DSS readiness.
Performance & Capacity Planning
Continuous performance tuning, resource right-sizing, and cost optimization. Auto-scaling policies that handle traffic spikes without over-provisioning.
Disaster Recovery & High Availability
Multi-AZ and multi-region architectures, automated failover, backup verification, and regular DR drills. RPO and RTO guarantees documented in runbooks.
SRE vs DevOps: How They Work Together
DevOps
Cultural philosophy focused on breaking silos between dev and ops. Handles CI/CD pipelines, build automation, infrastructure as code, and deployment workflows. DevOps answers "how do we ship faster?"
SRE
Specific implementation of DevOps with defined practices — SLOs, error budgets, toil reduction, blameless postmortems. Handles production reliability, on-call, and incident management. SRE answers "how do we keep it running?"
Together
Most mature organizations use both: DevOps for building and deploying, SRE for operating and maintaining. Our teams cover both — from pipeline setup to 24/7 production operations.
How Our SRE Team Operates
A structured approach to site reliability engineering that delivers measurable improvements in uptime, performance, and operational efficiency.
From infrastructure management to incident response, our SRE practice provides an end-to-end framework for operational excellence across AWS, Azure, and GCP environments.
Cloud Infrastructure Management
Manage compute, storage, networking, and container orchestration. Provisioning, scaling, IAM, backup management, and disaster recovery — all codified in Terraform.
Observability & Monitoring
Full-stack observability with Prometheus, Grafana, ELK, and Loki. Custom dashboards, SLO tracking, anomaly detection, and intelligent alerting that reduces noise.
Incident Management
24/7 on-call with PagerDuty integration. Automated detection, documented escalation paths, SLA-backed response times, and blameless postmortems for every significant incident.
Security & Compliance Operations
Regular security reviews, OS and database patching, vulnerability scanning, compliance audits, and firewall management. Continuous compliance for SOC 2, HIPAA, and PCI-DSS.
Release & Change Management
CI/CD pipeline support, rollback strategies, database change control, canary deployments, and post-deployment monitoring for zero-downtime releases.

SRE Onboarding: Your Path to Reliability
A structured onboarding process that transitions you to managed SRE operations with minimal disruption.
Discovery & Assessment
Deep dive into your current infrastructure, applications, and operational pain points. Audit architecture, dependencies, monitoring gaps, and incident history to build a reliability baseline.
SLO Definition & Planning
Define Service Level Objectives aligned with business goals. Establish error budgets, on-call rotations, escalation procedures, and incident severity classifications tailored to your organization.
Monitoring & Observability Setup
Deploy comprehensive monitoring, logging, and alerting. Set up Prometheus, Grafana, ELK dashboards for real-time visibility into system health, performance, and SLO compliance.
Runbook & Automation
Create detailed runbooks for incident response, escalation, and operational tasks. Build automation for common toil — auto-scaling, self-healing, automated patching, and certificate renewals.
Go-Live & Continuous Operations
Transition to 24/7 managed SRE operations. Continuous monitoring, incident response, monthly reliability reviews, and ongoing optimization with regular SLA reporting.
Who Needs SRE Services?
Site reliability engineering is essential for any organization where downtime means lost revenue, regulatory risk, or customer churn.
SaaS Platforms
Multi-tenant applications requiring 99.9%+ uptime, zero-downtime deployments, and real-time performance monitoring. SRE ensures your customers never see downtime.
FinTech & Banking
Transaction-critical systems with strict compliance requirements (PCI-DSS, SOC 2). SRE provides the operational rigor and audit trails regulators demand.
HealthTech
HIPAA-compliant infrastructure with zero tolerance for data loss. SRE ensures patient data systems remain available, secure, and compliant 24/7.
E-Commerce
Handle traffic spikes during sales events without outages. Auto-scaling, performance tuning, and rapid incident response that protect revenue during peak periods.
Startups Scaling Fast
Growing too fast to build an in-house SRE team? Our managed SRE gives you enterprise-grade operations from day one, so your engineers focus on product.
