Downtime is costly – cross-cloud resilience is survival. Disaster Recovery (DR) in multi-cloud Kubernetes ensures workloads stay online even if an entire region or provider fails. Here’s how SREs design it right. 1. Architecture Strategy Active-Active: both clusters handle traffic; use global load balancer (e.g., Cloudflare, Route 53). Active-Passive: secondary cluster on standby; synced via […]

Automation is the backbone of modern DevOps.It’s what converts human processes into reliable, repeatable, and scalable systems – from code commit to production monitoring. 1. Automate Infrastructure Use Terraform, Pulumi, or Crossplane for declarative provisioning. Store infra as code in Git for auditability and rollback. Example: terraform apply -auto-approve Integrate secrets via Vault or Sealed

Horizontal scalingadds more pods. Vertical scalinggives existing pods more resources. But when does VPA make sense in production-grade Kubernetes clusters? 1. Ideal Use Cases      Steady workloadswith predictable growth.      Memory-bound apps(e.g., Java, ML models).      Low pod count but high CPU/memory variability.      Non-latency-sensitive workloads (since VPA restarts pods on

Customer support is the first line of defense when issues arise. But most support engineers aren’t Kubernetes experts. When a pod fails or latency spikes, they often escalate to SREs – slowing down resolution and frustrating customers.KubeHA AI changes that. It gives support teams the same investigative powers as SREs by automatically analyzing logs, metrics,

Resilience isn’t proven by uptime – it’s proven by failure. Chaos Engineering is about injecting controlled failures into systems to uncover weaknesses before real outages happen. Done right, it’s not reckless – it’s a scientific way to harden Kubernetes clusters. 1. Start Small with Safe Experiments Always begin in staging clusters before production. Early experiments:

DevOps has evolved with AI, GitOps, and cloud-native platforms.But some best practices remain timeless — they continue to deliver value for teams in 2025. Infrastructure as Code (IaC) Use Terraform, Pulumi, Helm for repeatable infra deployments. Git is the single source of truth. GitOps for Continuous Delivery Tools like ArgoCD, Flux keep clusters in sync

From Downtime to Uptime – SRE Playbook Downtime costs more than money – it costs customer trust.For SREs, every second of downtime means lost transactions, SLA breaches, and reputational damage. The key to resilience isn’t avoiding failure (impossible) – it’s detecting, diagnosing, and remediating fast. This is the SRE Playbook for turning downtime into uptime.

Pod Troubleshooting – SRE’s Fast Lane When a pod fails in Kubernetes, every second counts.SREs need to quickly determine if the issue is due to configuration errors, resource limits, or application-level failures. The key is to follow a fast, structured troubleshooting flow that reduces MTTR. Start with Pod Status Run: kubectl get pods -n <namespace>

Shift-Left Security in Kubernetes Security can’t be an afterthought in Kubernetes. In fast-moving DevOps pipelines, leaving security checks until production means vulnerabilities are caught too late. The solution is Shift-Left Security — bringing security earlier into the CI/CD lifecycle. 1. Why Shift-Left Matters in Kubernetes Containers move from dev to prod in minutes. Without security

Each provider has its own IAM, networking, observability, and compliance quirks. The real challenge is making them all work together

Automate Alert Remediation Before Your Coffee Gets Cold Why should SREs wake up to fix something the cluster could have fixed itself? In Kubernetes, alerts are inevitable: pods OOMKilled, nodes NotReady, CrashLoopBackOff, failing probes. Traditional observability stacks (Prometheus + Grafana + Alertmanager) detect these failures, but remediation still relies on engineers. That means lost sleep,
