    DevOps is understanding problems, automating solutions, and working as one team.

    If you focus on:
    Learning fundamentals
    Building automation
    Being curious
    Continuous improvement

    …you will grow very fast in this field

    Next Steps :

  • How to prioritize which DevOps skills to learn first

    To prioritize which DevOps skills to learn first, focus on building a strong foundation in the core competencies that will enable you to effectively contribute to DevOps processes and projects early on. Here’s a recommended approach

    Step 1: Learn Operating Systems + Scripting

    DevOps runs mostly on Linux — so start here!

    • Learn Linux basics (commands, users, permissions, services)
    • Practice Shell scripting (Bash)
    • Learn Python to automate tasks

    This gives you the power to control systems efficiently and it is must DevOps skills to learn.

    Step 2: Master Git + CI/CD Pipelines

    Version control is required everywhere:

    • Learn Git (branching, merging, GitHub/GitLab)
    • Understand CI/CD concepts
    • Start using tools like:
      • Jenkins
      • GitHub Actions
      • GitLab CI

    This helps automate software delivery.

    Step 3: Infrastructure as Code (IaC) + Configuration Management

    DevOps = automation everywhere.

    • Learn Terraform for provisioning infrastructure
    • Learn Ansible or Puppet to configure servers automatically

    These tools help manage systems at scale.

    Step 4: Containers + Kubernetes

    Most modern apps run in containers.

    • Start with Docker (images, containers, registries)
    • Then learn Kubernetes (pods, deployments, clusters)

    This skill is one of the most important for DevOps jobs in 2025 and beyond.

    Step 5: Monitoring + Logging

    To keep systems healthy, you must track performance:

    Tools to learn:

    • Prometheus (metrics & alerts)
    • Grafana (dashboards)
    • ELK Stack or Splunk (log analysis)

    This helps detect issues before users are impacted.

    Step 6: Networking + Security Basics

    Every DevOps role requires:

    • Basic networking (DNS, firewalls, ports, routing)
    • DevSecOps awareness
    • Security best practices

    Security must be integrated into every step of DevOps.

    Step 7: Soft Skills

    DevOps = collaboration between teams.

    Work on:

    • Communication
    • Teamwork
    • Problem-solving
    • Analytical thinking

    These skills make you stand out.

    Learn Based on Your Career Goals

    If you’re already working in:

    • Cloud environments → Learn AWS/Azure + cloud certifications
    • Development teams → Focus more on CI/CD + automation
    • Operations roles → Start with Linux + IaC + monitoring

    There’s no single right path — choose skills that match your interests.

    Final Thoughts: Keep Learning and Building

    DevOps is a fast-changing world.
    The best way to grow is by practicing:

    Work on labs
    Build real projects
    Contribute to automation
    Experiment with new tools

    Following this roadmap gives you:
    A strong foundation
    Job-ready skills
    Clear path to senior DevOps engineering roles

    Next Steps :

  • AWS DevOps Engineer vs OCI DevOps Engineer: A Clear Comparison

    In today’s cloud-driven world, DevOps engineers play a critical role in building, deploying, and maintaining applications. But depending on the cloud provider, the role of a DevOps engineer can look very different. Two leading cloud platforms—Amazon Web Services (AWS) and Oracle Cloud Infrastructure (OCI)—both offer DevOps tools and services. In this blog, we’ll compare what it means to be an AWS DevOps Engineer vs an OCI DevOps Engineer.

    1. Core Focus of the Role

    • AWS DevOps Engineer:
      Focuses on designing and managing CI/CD pipelines, infrastructure automation, and scaling applications using AWS services like CodePipeline, CodeBuild, CodeDeploy, CloudFormation, Elastic Beanstalk, ECS/EKS, and Lambda.
    • OCI DevOps Engineer:
      Works on building CI/CD pipelines using OCI DevOps service, automating deployments with Resource Manager (Terraform-based), and ensuring workloads run efficiently on OCI Compute, Kubernetes (OKE), and Autonomous Database.

    Key Difference: AWS engineers rely on a mature and wide ecosystem, while OCI engineers focus on a simplified, integrated DevOps service with Terraform as a central tool.

    2. Tools and Services

    • AWS DevOps Tools:
      • CI/CD: CodePipeline, CodeBuild, CodeDeploy
      • Infrastructure as Code (IaC): CloudFormation, CDK, Terraform
      • Containers & Orchestration: ECS, EKS (Kubernetes), Fargate
      • Monitoring & Logging: CloudWatch, X-Ray
      • Security: IAM, Secrets Manager, KMS
    • OCI DevOps Tools:
      • CI/CD: OCI DevOps (built-in pipelines, build & deployment automation)
      • Infrastructure as Code (IaC): Resource Manager (native Terraform service)
      • Containers & Orchestration: OKE (Oracle Kubernetes Engine)
      • Monitoring & Logging: OCI Logging, Monitoring, and Alarms
      • Security: OCI IAM (policies, compartments, dynamic groups)

    Key Difference: AWS has more tool variety (but higher complexity). OCI provides fewer but tightly integrated tools that revolve around Terraform and simplified DevOps flows.

    3. Ecosystem & Integrations

    • AWS: Has a massive ecosystem—DevOps engineers integrate S3, Lambda, DynamoDB, RDS, and countless services into their CI/CD pipelines.
    • OCI: Offers integration mainly within Oracle products like Autonomous Database, Fusion apps, and Analytics, but also supports S3 API compatibility for easier migration.

    AWS = Broad ecosystem. OCI = Oracle-centric integrations.

    4. Skill Requirements

    • AWS DevOps Engineer Skills:
      • Deep understanding of AWS DevOps tools (CodePipeline, CloudFormation, etc.)
      • Strong knowledge of containerization (Docker, Kubernetes)
      • Experience in monitoring & scaling (CloudWatch, Auto Scaling)
      • Certification like AWS Certified DevOps Engineer – Professional is highly valued
    • OCI DevOps Engineer Skills:
      • Hands-on with OCI DevOps service and Resource Manager (Terraform)
      • Knowledge of OCI networking, compute, and compartments
      • Familiarity with Oracle Autonomous Database integration
      • Certification like Oracle Cloud Infrastructure DevOps Professional (in beta/rolling out) adds credibility

    AWS engineers often need multi-tool expertise, while OCI engineers must be strong in Terraform + Oracle integrations.

    5. Job Market & Demand

    • AWS DevOps Engineer:
      • High demand globally.
      • Most enterprises use AWS, making it the most sought-after DevOps skillset.
      • Salaries are among the top in cloud engineering.
    • OCI DevOps Engineer:
      • Niche but growing demand, especially in enterprises already invested in Oracle products (finance, banking, manufacturing).
      • Salaries are competitive, but fewer job listings compared to AWS.

    AWS = Global dominance. OCI = Specialized opportunities.

    6. Pricing & Business Impact

    • AWS DevOps Engineers: Must optimize costs across many AWS services. Complexity can increase costs if not managed well.
    • OCI DevOps Engineers: Often highlight lower cloud pricing (Oracle markets OCI as cheaper than AWS), focusing on cost efficiency.

    7. Career Growth

    • AWS DevOps Engineer:
      • Broader career opportunities (SRE, Cloud Architect, Platform Engineer).
      • Skills are transferable across industries and regions.
    • OCI DevOps Engineer:
      • Strong career growth inside Oracle-centric enterprises.
      • Skills are more niche, but valuable in industries tied to Oracle databases and ERP systems.

    Conclusion

    • Choose AWS DevOps Engineer if:
      • You want to work in a wide range of industries.
      • You value career flexibility and global demand.
      • You want to master the world’s most popular cloud platform.
    • Choose OCI DevOps Engineer if:
      • You are working in an Oracle-heavy environment (banking, finance, ERP).
      • You prefer simplicity with Terraform-driven automation.
      • You want to specialize in a niche with less competition.

    In short:

    • AWS DevOps Engineer = Broad, high-demand, versatile.
    • OCI DevOps Engineer = Niche, Oracle-focused, cost-efficient
