Introduction: Why Reliability is a Business Imperative
In today’s always-connected, digital-first world, downtime isn’t just an inconvenience—it’s a dealbreaker.
🚫 A minute of unavailability can lead to lost revenue.
🚫 A slow service can frustrate users.
🚫 A system crash can tarnish trust.
To fight these challenges, Heyme Software embraces Site Reliability Engineering (SRE)—a discipline that bridges the gap between software engineering and IT operations. With SRE, we ensure performance, availability, and scalability, even as demand grows and systems become more complex.
🔍 What is Site Reliability Engineering (SRE)?
SRE is a set of principles and practices developed by Google to help organizations build and operate scalable, highly reliable software systems.
It blends software engineering with operations to:
- Automate infrastructure
- Improve system reliability
- Monitor performance
- Respond quickly to incidents
- Balance innovation and stability
At its core, SRE aims to make systems better with code—not just processes.
🚀 Heyme’s SRE Mission: Zero Downtime, Maximum Efficiency
At Heyme, the goal of SRE is simple:
Keep everything running smoothly—whether that’s SMS campaigns, analytics dashboards, AI chatbots, or mass data processing.
🔧 Core Principles of SRE at Heyme
1. SLIs, SLOs, and SLAs
- Service Level Indicators (SLIs) measure reliability (e.g., request latency, error rate).
- Service Level Objectives (SLOs) define acceptable targets (e.g., 99.95% uptime).
- Service Level Agreements (SLAs) are formalized expectations with customers.
By tracking these metrics, we maintain transparency and accountability.
2. Error Budgets
Innovation vs. reliability? It’s a balancing act.
An error budget defines how much unreliability is acceptable (based on SLOs). This allows Heyme to:
- Release features quickly—as long as reliability goals are met
- Pause deployments if stability is at risk
- Align Dev and Ops around shared goals
3. Automation Over Manual Ops
We believe "Toil is the enemy." Toil = repetitive, manual, and automatable tasks.
SREs at Heyme automate:
- CI/CD pipelines
- Infrastructure provisioning (with Terraform)
- Monitoring and alerting setups
- Rollbacks and auto-scaling
- Database failovers and backups
4. Proactive Monitoring & Observability
We use real-time observability tools like:
- Prometheus for metrics
- Grafana for dashboards
- ELK Stack for logs
- OpenTelemetry for distributed tracing
This allows Heyme to detect, diagnose, and resolve issues before users even notice.
5. Incident Management & Postmortems
Despite best efforts, incidents can happen.
Heyme follows a blameless incident response process:
- On-call engineers use playbooks to triage quickly
- Incidents are documented and reviewed in-depth
- Postmortems focus on learning, not blaming
- Remediation tasks are tracked and prioritized
