IT Glossary for Recruiters

What is Production?

Production is the stage where software or systems are fully deployed and actively used by real customers. It marks the final product in the software development process, where it is no longer in testing but is operational and available for its intended users.

Why is Production so important?

  • Direct Impact on Customers:
    Production systems are used by end-users. Any error can disrupt their experience. For example, an e-commerce website going offline can stop customers from shopping.

  • Revenue Generation:
    Many businesses rely on their production systems for income. If the system fails, it can lead to lost sales or missed opportunities.

  • Company Reputation:
    A well-functioning production system builds trust with users. Frequent downtime or bugs can harm the company’s image.

Stages before Production


Development

Developers write the code and create the basic functionality. This is the starting point for all projects.

Testing or Quality Assurance (QA)

Testing teams check for bugs and errors. They ensure the software is functional and meets user requirements.

Staging

Staging is a copy of the production environment used for final tests. It replicates real-world conditions but isn’t accessible to end-users.

Production

The final stage is where the software is released and used by its intended audience. At this point, it must be reliable and secure.

Roles involved in managing Production

DevOps Engineers:
They automate deployments and monitor system performance. DevOps professionals ensure the software runs efficiently after launch.
Site Reliability Engineers (SREs):
These experts focus on making systems reliable and scalable. They monitor uptime and quickly resolve incidents.
Release Managers:
Release managers coordinate the transition of software from development to production. They ensure launches without disruptions.
IT Operations Staff:
These professionals provide ongoing support and handle system maintenance.

Challenges of working in Production

Downtime: If the system crashes, it can result in lost revenue and frustrated users. For instance, a banking app going offline can prevent customers from accessing their accounts.Security Threats: Production systems are prime targets for cyberattacks. Professionals must ensure they’re protected against breaches and vulnerabilities. Scalability: Systems in production often face sudden spikes in usage. For example, during holiday sales, an e-commerce platform might see higher traffic. The system must handle the load without slowing down.Updates and Changes: Introducing updates to production can sometimes cause issues. Teams need to deploy changes carefully to avoid breaking the system.

Benefits of Production

    Production allows end-users to interact with the software in real-world.
    Businesses earn income as the product becomes available for customers to use or purchase.
    Companies can engage with their audience, improve user satisfaction, and build loyalty.
    A product in production signifies that it has passed all development and testing stages and is ready for its intended purpose.

Drawbacks of Production

    Failures in the production environment can disrupt customer experience, harm the business's reputation, and cause revenue loss.
    Errors in production often have greater consequences compared to development or testing stages.
    Production systems are prime targets for cyberattacks, making robust security practices a necessity.
    Changes or updates must be thoroughly tested before deployment to production.

Best practices for Production

Continuous Monitoring

Regularly track system performance, including uptime, response times, and resource usage, to identify and address issues early.

Automated Deployments

Implement CI/CD pipelines to automate software deployments and updates, reducing human error and ensuring consistency.

icon

Backup and Recovery

Perform regular automated backups of critical data and configurations to safeguard against data loss or system failures.

Security Best Practices

Keep security patches up to date, encrypt sensitive data, and implement strict access controls to protect the production environment from threats.

Scalability

Design the system to handle increased traffic through load balancing and ensure it can scale to accommodate growth.

Incident Management

Have a clear plan for responding to production issues, including incident tracking tools, and post-incident reviews to prevent future occurrences.
