  • DevOps vs SRE differences and when to use each

    DevOps and Site Reliability Engineering (SRE) have overlapping goals but differ significantly in focus, responsibilities, and approaches. we will see DevOps vs SRE differences in this article.

    Key Differences

    Focus:

    • DevOps focuses on the entire software development lifecycle, emphasizing collaboration between development and operations to deliver features quickly and reliably.
    • SRE focuses narrowly on system reliability, scalability, and stability in production, ensuring that changes do not increase failure rates or disrupt user experience.

    Responsibilities:

    • DevOps teams build and deploy new features, streamlining development and deployment pipelines with continuous integration and delivery practices.
    • SRE teams ensure production systems remain highly available and performant, using engineering practices to automate operations, monitor production, and handle incidents proactively.

    Objectives:

    • DevOps aims to accelerate product development and delivery to meet customer needs.
    • SRE aims to maintain service uptime and reliability, often setting and enforcing service-level objectives (SLOs) and error budgets.

    Team Structure:

    • DevOps teams integrate roles across software development and operations.
    • SRE teams consist of engineers skilled in both software and operations, focusing deeply on reliability engineering.

    Approach to Failures:

    • DevOps is more reactive, fixing problems as they appear and focusing on fast delivery.
    • SRE is proactive, analyzing root causes, performing chaos engineering, and preventing failures before they occur.

    When to Use Each

    • Use DevOps when you want to improve collaboration between development and operations, speed up software delivery, and implement continuous integration/delivery pipelines.
    • Use SRE when your priority is to maintain high reliability and availability of systems at scale, reduce downtime, and manage operational risk through data-driven reliability engineering practices.

    Main Differences: DevOps vs SRE

    FeatureDevOpsSRE
    Primary GoalSpeed & DeliveryReliability & Stability
    Main FocusEntire SDLC (plan → deploy)Production systems
    Mindset“Move fast”“Don’t break things”
    Approach to IssuesReactive + Continuous improvementProactive + Automated
    Key MetricsDeployment frequency, delivery timeUptime, error rate
    Who does it?Developers + Ops teamsSpecialized reliability engineers

    In essence, DevOps defines the broad culture and practices for faster development and deployment, while SRE applies engineering rigor to keep those deployed systems reliable in production. Organizations often integrate both for achieving fast, stable, and scalable software delivery

    Final Thoughts

    DevOps + SRE Better Together

    Here’s the secret:
    Most organizations don’t choose one over the other.

    DevOps = culture + speed
    SRE = discipline + reliability

    Together, they create a balanced system:

    • DevOps pushes updates quickly
    • SRE ensures updates don’t break the system

    Fast + Stable = Happy Users + Happy Business

  • Essential Ports and Protocols Every DevOps Engineer Should Know

    As a DevOps engineer, your work doesn’t stop at CI/CD pipelines or writing infrastructure-as-code. You’re also a bridge between development, operations, and the underlying network that makes everything talk to each other.should know Ports and Protocols.

    And here’s the truth: if you don’t understand the ports and protocols your systems rely on, troubleshooting production issues or securing them becomes a nightmare.

    So let’s break down the networking essentials every DevOps engineer should know — the ports and protocols, and why they matter in your daily workflow.

    1. Core Web and Application Protocols

    These are the backbone of Application — if your app touches the internet, you’re using these.

    ProtocolPortTransportWhy It Matters for DevOps
    HTTP (Hypertext Transfer Protocol)80TCPHandles unsecured web traffic. Typically used for redirects to HTTPS. Make sure your web servers (like Nginx or Apache) listen here only for redirection.
    HTTPS (HTTP Secure)443TCPEncrypts web communication using SSL/TLS. Ingress controllers, CDNs, and app servers must handle TLS certificates and termination correctly.
    DNS (Domain Name System)53UDP/TCPResolves domain names to IPs. Misconfigured DNS can break deployments, service discovery, or even CI/CD pipelines.

    Always validate your DNS records and automate certificate renewals (using something like cert-manager in Kubernetes).

    2. Infrastructure & Remote Access Protocols

    You’ll use these daily for server management, deployments, and automation.

    ProtocolPortTransportWhy It Matters
    SSH (Secure Shell)22TCPThe lifeline for secure remote access to Linux/Unix servers and CI/CD agents. Best practice: Change the default port and restrict access via firewalls or security groups.
    RDP (Remote Desktop Protocol)3389TCPUsed for graphical access to Windows servers. Even if you’re mostly cloud/Linux, it’s essential when managing Windows build agents or hybrid environments.

    Lock down SSH and RDP to specific IPs or use bastion hosts — never expose them directly to the internet.

    3. Database & Messaging Protocols

    If your app stores or moves data, these ports are the lifelines. They also happen to be common attack targets.

    ProtocolPortTransportWhy It Matters
    MySQL3306TCPStandard for MySQL/MariaDB. Should never be publicly accessible allow only internal traffic.
    PostgreSQL5432TCPPopular open-source database. Same rule: restrict access tightly.
    MongoDB27017TCPDefault MongoDB port. Enable authentication and firewall restrictions.
    Redis6379TCPUsed for caching and session storage. Protect it — Redis often holds sensitive in-memory data.
    MQTT1883 / 8883 (secure)TCPCommon in IoT and microservice messaging. Know these if managing brokers like Mosquitto.

    Treat database ports like secrets — only your app should be talking to them.

    4. Operational & Monitoring Ports

    These keep your systems observable, automatable, and healthy.

    Tool / ServicePortTransportWhy It Matters
    Jenkins8080TCPDefault for Jenkins and many CI/CD tools. Watch for port conflicts in shared environments.
    Prometheus9090TCPExposes metrics for scraping. Make sure Grafana or other dashboards can reach it.
    Grafana3000TCPDefault web UI for visualization dashboards.
    Kubernetes API Server6443TCPThe control plane’s main entry point. Lock it down with RBAC and network policies.
    Health ChecksVaries (e.g., 8080/8081)TCPUsed by Kubernetes or load balancers for readiness/liveness probes. Keep them lightweight and reliable.

    Ports Are Policy

    Understanding ports isn’t just about memorizing numbers — it’s about enforcing good security and operational practices.

    Here’s how to apply this knowledge:

    • Principle of Least Privilege: Only open what’s absolutely necessary. Close everything else.
    • Use FQDNs over IPs: DNS simplifies environment management and scaling — let names handle the routing.
    • Audit Regularly: Tools like ss, netstat, or Kubernetes kubectl port-forward can show you exactly what’s exposed.
    • Embrace HTTPS: Port 80 should exist only to redirect traffic to 443. Automate SSL/TLS renewal and rotation.

    Final Thoughts

    Networking isn’t just the concern of your infrastructure team .it’s part of your DevOps DNA. By mastering ports and protocols, you’re not just connecting services; you’re building reliable, secure, and scalable systems that stand strong under real-world traffic.

    After all, every deployment travels across the network — make sure you understand the roads it takes

    What’s Next?

    The journey is ongoing. I’m glad to have you along for the ride.

  • My DevOps Journey: From Leather Tech to Cloud Engineering

    Hello all Devops & Developers!

    My name is Srikanth,and this is the first post in my public learning journey. I’m currently a DevOps Engineer at Zoho Corporation but my path to get here was anything but straight. This blog is my attempt to document my continuous learning in the world of DevOps and share the lessons I pick up along the way.

    My story begins in a small village where the idea of a career in cutting-edge technology felt a world away. I worked hard, secured a place at Anna University in Chennai and pursued a degree in… Leather Technology. It was a fascinating field and I was proud to be placed in a core company right after graduation.

    But just four months in, I had a nagging feeling that I was on the wrong path. The work wasn’t igniting my passion. I made a tough decision: I quit my job to chase a curiosity that had been growing for a while – the world of cloud computing.

    This was my pivot point. I enrolled in the AWS re/Start program, a full-time, online-based course that takes you from zero to cloud-ready. I immersed myself, studied relentlessly and earned my first AWS certification. That certification was more than a piece of paper; it was my entry ticket. In August 2023, I landed my first tech role as a DevOps Engineer at a startup.

    For nine incredible months, I learned more than I ever thought possible. The startup environment was a trial by fire, and it solidified my love for building, automating, and solving complex problems. That experience paved the way for my current role at Zoho Corporation.

    Why I’m Sharing This Journey

    Even though I’m now working in the field, I firmly believe that in DevOps, you are never done learning. The landscape of tools and best practices is constantly evolving. My goal for this blog is to create a space for continuous growth. This won’t be a polished tutorial series from an expert. This is a real-time log from a practicing engineer who is always learning.

    Let’s Learn and Grow Together

    I’m putting my learning goals out there to hold myself accountable, but I also want to build something more: a community.

    My vision is for this blog to be an interactive space. Join me in the comments with your own studies and queries. Let’s share learning skills, help each other with debugging complex issues, and grow as a community. We can all become better engineers when we grow as a group. This is our space to learn and grow, together.

    What’s Next?

    The journey is ongoing. I’m glad to have you along for the ride.

  • Practical Strategies for Implementing DevOps Successfully

    DevOps — it’s more than a buzzword. It promises faster delivery, improved collaboration, better-quality software, and reduced time to market. But for many teams, DevOps remains a lofty goal rather than a practical reality.

    If you’ve ever felt overwhelmed by the countless tools, frameworks, and shifting responsibilities, you’re not alone. The challenge isn’t about lacking resources; it’s about navigating complexity and driving real, sustainable change.

    Instead, start small with a well-defined pilot project that acts as a proving ground.

    How to Do It:

    • Pick a low-risk application — something non-critical where failure won’t be catastrophic.
    • Assemble a cross-functional team — include devs, ops, QA, and product owners to break silos early.
    • Target a specific pain point — slow deployment? Poor feedback loops? Focus on solving one problem with DevOps principles.

    Tip: A successful pilot builds internal case studies, showing real benefits and creating champions for broader adoption.

    Automate, Automate, Automate — But Do It Smartly

    At its core, DevOps is about automation—but not blind automation. The goal is to free your teams from repetitive, error-prone tasks so they can focus on innovation and delivery.

    Key Areas to Automate:

    • Version Control Everything
      Not just code—put infrastructure, config files, and test scripts in Git. IaC (Infrastructure as Code) is non-negotiable.
    • Build CI/CD Pipelines
      Implement Continuous Integration and Continuous Delivery using tools like Jenkins, GitLab CI/CD, GitHub Actions, or Azure DevOps.
    • Automate Testing
      Include unit, integration, and performance tests in your pipeline to catch bugs early.
    • Automate Infrastructure Provisioning
      Use tools like Terraform, Ansible, or Pulumi to provision environments consistently and reproducibly.

    Start small: Automate the most time-consuming or failure-prone manual processes first.

    Foster a Culture of Collaboration and Shared Responsibility

    DevOps isn’t just about tools—it’s a cultural transformation. The hardest part of DevOps is often human, not technical.

    Culture Hacks for DevOps Success:

    • Blameless Postmortems
      Focus on learning, not blaming. Encourage transparency after incidents.
    • Shared Goals & Metrics
      Developers and Ops should align around KPIs like uptime, lead time, and incident recovery rate.
    • Cross-Training
      Let developers understand infra, and ops understand code. Hold regular internal workshops and pair programming sessions.
    • Feedback Loops
      Build systems where teams get real-time feedback on how code performs in production.

    DevOps thrives when teams own the entire lifecycle—from development to deployment to operations.

    Prioritize Observability: Monitoring and Logging from Day One

    You can’t fix what you can’t see. Without visibility, DevOps collapses into guesswork. Robust monitoring and logging are essential for healthy operations.

    Observability Essentials:

    • Centralized Logging
      Use tools like the ELK Stack, Splunk, or Datadog to aggregate logs for fast troubleshooting.
    • Monitoring Key Metrics
      Watch CPU, memory, disk I/O, application latency, and user behavior.
    • Set Up Alerts
      Configure smart alerts to detect anomalies before users do.
    • Distributed Tracing
      Especially in microservices, tracing tools like Jaeger, Zipkin, or OpenTelemetry help track issues across services.

    From Day 1, embed observability into your workflows to shift from reactive firefighting to proactive problem-solving.

    DevOps Is a Journey, Not a Destination

    DevOps isn’t a one-and-done transformation. It’s a continuous improvement mindset. It requires:

    • Technical excellence
    • Collaborative culture
    • Data-driven decision-making
    • A willingness to adapt

    By starting small, automating smartly, fostering collaboration, and prioritizing observability, your organization can move beyond the hype and start realizing DevOps’ full potential—delivering high-quality software quickly, safely, and at scale.

    Introduction

    You may have heard of a software developer or a system administrator. But what about a DevOps Engineer? Who are they? What do they actually do?

    In this blog, you’ll get a clear understanding of the role of a DevOps Engineer, why they’re important, and what tools and skills they use every day.

    Let’s break it down in a simple, professional, and easy-to-understand way.

    Who is a DevOps Engineer?

    A DevOps Engineer is someone who works at the center of software development and IT operations.

    Their main goal?

    Make sure code written by developers gets tested, deployed, and monitored smoothly without errors.

    They:

    • Help developers release updates faster
    • Automate everything from testing to deployment
    • Monitor systems to keep everything running

    What Does a DevOps Engineer Actually Do?

    Here are the core responsibilities:

    1. Collaboration

    They work with developers, testers, and IT teams to make sure everyone is on the same page.

    2. Automation

    They build systems that automate repetitive tasks like:

    • Code building
    • Testing
    • Deployment
    • Monitoring

    3. CI/CD Management

    They manage Continuous Integration and Continuous Delivery (CI/CD) pipelines. These are like smart machines that:

    • Take code from developers
    • Automatically test it
    • Deliver it to users without human effort

    4. Infrastructure as Code (IaC)

    DevOps Engineers treat servers like code. They use tools to:

    • Set up infrastructure with scripts (like writing instructions for computers)
    • Recreate environments quickly and safely

    5. Monitoring and Logging

    They set up systems that:

    • Watch how apps are running
    • Log any issues or crashes
    • Alert the team immediately

    6. Security and Backup

    They also add security checks and make sure backups are in place in case something goes wrong.
