Site Reliability Engineering principles, SLIs/SLOs, incident management, observability, and reliability best practices
Ask any developer what keeps them awake at night during a major release, and nine times out of ten the answer is schema migrations. Dropping a column, renaming a table, or altering a foreign key constraint on a live production database while traffic is hitting your API can cause cascading failures and catastrophic downtime. For […]
Slow app? Before buying more cloud CPU, tune the actual bottleneck: how SMBs find and fix PostgreSQL performance with EXPLAIN, indexes, and pooling.
Pod evictions are the invisible killer of reliability. Spot node pressure early, right-size requests, and add PDBs before an eviction wakes you at 3 a.m.
Your first Prowler scan will find hundreds of cloud misconfigurations — and nobody will fix them. Here is a triage workflow that actually closes tickets.
Log ingestion and retention are quietly eating your budget. Cut observability costs by 50%+ with Loki, Fluent Bit sampling and retention tiers.
Kubernetes rolling updates are a coin flip. Argo Rollouts gives SMBs canary and blue-green deployments with automated rollback — and zero downtime.
One bad kubectl delete can wipe your cluster. Back up Kubernetes properly with Velero: schedules, restores, and DR drills that actually work.
Running a Kubernetes cluster several versions behind is a ticking time bomb. Learn a practical, low-risk upgrade strategy for lean SMB teams.
What Is Policy as Code? Policy as Code (PaC) is the practice of defining and enforcing rules for your infrastructure and applications using code — rather than manual processes, spreadsheets, or wiki pages. Instead of asking “Did the security team approve this change?”, you let your pipeline automatically check: “Does this deployment satisfy our defined
Why Error Budgets Matter More Than Uptime Most SMBs measure reliability by a single metric: uptime. “We need 99.9% availability” sounds great in a board meeting, but it’s a terrible operational target. Uptime tells you if your service was running, not if it was working. It doesn’t distinguish between a 3-second blip during off-hours and
