Welcome to My DevOps Journey
A DevOps Engineer's perspective on Cloud Infrastructure and Automation

Welcome to My DevOps Journey
As a DevOps engineer, I've had the opportunity to work with various modern technologies and practices. This blog will be a platform for sharing practical knowledge, best practices, and real-world insights gained from hands-on experience in the field.
Cloud Service Providers (CSP)
- AWS Architecture and Services
- EC2, EKS, Lambda, S3, RDS, DynamoDB
- CloudFormation, CDK, IAM
- VPC, Security Groups, Route 53
- Google Cloud Platform (GCP) Implementations
- GCE, GKE, Cloud Functions
- BigQuery, CloudSQL, Cloud Storage
- Cloud Build, Cloud Run
- Multi-cloud Strategies and Best Practices
- Abstraction layers and unified management
- Cost optimization across platforms
- Disaster recovery and redundancy planning
CI/CD & Automation
GitOps Principle
GitOps uses Git repositories as the single source of truth for infrastructure and deployments. Any change to the system begins with a commit to Git, triggering automated processes to align the actual state with the desired state.
- Git-based Workflows
- GitHub Actions workflows and custom actions
- GitLab CI pipeline optimization
- Jenkins automation and shared libraries
- Deployment Strategies
- ArgoCD and Flux for GitOps
- Blue-Green deployments
- Canary releases and feature flags
- Infrastructure as Code (IaC)
- Terraform modules and state management
- Ansible playbooks and roles
- Pulumi with TypeScript and Python
- Custom automation tools and scripts
Container & Orchestration
Technology | Purpose | Key Features |
---|---|---|
Kubernetes | Container orchestration | Auto-scaling, self-healing, rolling updates |
Docker | Containerization | Image building, multi-stage builds, Docker Compose |
Helm | Package management | Templating, release management, chart repositories |
Service Mesh | Network infrastructure | Traffic management, security, observability |
Ingress Controllers | External access | Routing, SSL termination, load balancing |
- Advanced Kubernetes Management
- Custom controllers and operators
- Multi-cluster management and federation
- Resource optimization and cost management
- Specialized Services
- Certificate management with cert-manager
- Container registry with Harbor
- Storage solutions with Ceph and MinIO
Database Management
Database Selection Criteria
- Data Structure: Relational vs Document vs Key-Value
- Scalability Requirements: Vertical vs Horizontal scaling
- Consistency Needs: ACID vs BASE properties
- Query Patterns: Complex joins vs Simple lookups
- Operational Complexity: Managed services vs Self-hosted
- Relational Databases
- MySQL/MariaDB high availability setups
- PostgreSQL optimization and performance tuning
- AWS RDS management and monitoring
- NoSQL Solutions
- MongoDB replica sets and sharding
- DynamoDB capacity planning
- Redis caching strategies and persistence options
- Message Queues and Streaming
- RabbitMQ clustering
- Kafka topic management
- AWS SQS/SNS implementations
Monitoring & Observability
- Metrics Collection and Visualization
- Prometheus and Grafana dashboards
- Thanos for metrics scaling and long-term storage
- Custom exporters and metrics
- Logging Solutions
- Loki and Promtail for log aggregation
- Fluent Bit log forwarding
- ELK Stack customization and scaling
- Tracing and APM
- Jaeger distributed tracing
- OpenTelemetry instrumentation
- Service performance monitoring
Security & Compliance
Security-First Approach
In modern DevOps, security must be integrated throughout the entire development and operations lifecycle, not added as an afterthought. This "shift-left" approach to security helps identify and address vulnerabilities early in the development process.
- Secrets Management
- HashiCorp Vault deployments and policies
- Kubernetes secrets integration
- Vaultwarden self-hosted password management
- Policy as Code
- Kyverno policy management
- OPA Gatekeeper implementation
- Infrastructure security scanning and compliance
- Access Control
- RBAC implementation in Kubernetes
- Identity and access management in cloud environments
- Zero trust network architecture
Storage Solutions
- Kubernetes Storage
- Rancher Local Path Provisioner
- NFS Subdir External Provisioner
- Ceph CSI implementation
- Persistent volume management
- Backup Strategies
- Velero for Kubernetes backup
- Restic integration
- Cross-region backup solutions
- Storage Optimization
- Performance benchmarking
- Capacity planning
- Data lifecycle management
Operating Systems & Infrastructure
- Linux Administration
- Ubuntu, CentOS, Rocky Linux
- Alpine Linux optimization
- Amazon Linux and Debian management
- Infrastructure Maintenance
- Patching strategies
- Configuration management
- Node lifecycle management
Development & Scripting
- Automation Languages
- Python for infrastructure automation
- Bash scripting for system tasks
- Go development for custom tools
- JavaScript/TypeScript for cloud automation
What to Expect
In the coming posts, I’ll dive deep into each of these topics, sharing:
- Step-by-step tutorials for common DevOps tasks
- Real-world case studies from production environments
- Performance optimization techniques
- Cost management strategies
- Troubleshooting guides for complex issues
- Architecture designs and best practices
Stay tuned for detailed posts about each of these topics! I’ll be sharing practical experiences, best practices, and real-world implementations of these technologies.
