Night Owl studying roadmap curriculum

1. Who It Is For

  • Students targeting Site Reliability Engineer (SRE), Cloud Engineer, or Platform Engineer roles.
  • Engineers fascinated by high availability, networking topologies, and automated operations.

2. Core Skills & Competency Matrix

Operating Systems & Networking

3. Structured Learning Path

1

Linux Kernel Internals & Network Troubleshooting

Weeks 1–6

Master process management, memory paging, iptables, and socket diagnostics.

Key Topics:strace & lsof debuggingSubnetting & CIDR calculationsTLS handshakesCgroups configuration
2

Container Runtime Engines & Cluster Architecture

Weeks 7–14

Package microservices, configure container networks, and administer production Kubernetes clusters.

Key Topics:Pod lifecycle hooksStatefulSets vs DeploymentsNetwork policiesStorage classes & PVCs
3

Declarative Infrastructure as Code (IaC) & GitOps

Weeks 15–20

Provision multi-region cloud topology using Terraform and automate continuous deployment with ArgoCD.

Key Topics:Terraform state managementModular IaC designGitOps reconciliation loopsSecrets management (Vault)

4. Verified Capstone Projects

5. Career Lab: Resume Crafting Guidance

  • List concrete infrastructure automation accomplishments: cluster scaling, deployment time reduction, or cost optimization.
  • Showcase Terraform modules or Helm charts hosted on public GitHub repositories.

6. Technical Interview Preparation

  • 1.Explain the exact flow of what happens when a Kubernetes pod crashes and how kubelet restarts it.
  • 2.Describe how Linux cgroups enforce memory limits and trigger OOM killer.
  • 3.System design: design a global high-availability CDN with zero-downtime failover.

7. Placement Strategy & Target Tiers

Cloud Hyper-Scalers & SaaS
Timeline: Months 6–9 of preparation
Core Focus:
  • Operating system internals
  • Distributed systems
  • Golang/Python automation
Sample: AWS, Microsoft Azure, Google Cloud, Cloudflare
FinTech & Enterprise Platform Teams
Timeline: Months 4–7 of preparation
Core Focus:
  • Security compliance
  • High availability (99.99%)
  • Kubernetes administration
Sample: JPMorgan Chase, Goldman Sachs, Morgan Stanley, PayPal

8. Next Steps & Recommended Path

  • Build the Zero-Trust Cloud Gateway capstone in Project Lab.
  • Review operating system and mutex concurrency questions in the Interview Hub.
  • Deploy a sample Kubernetes cluster on local Kind or Minikube.
