How I Approach Enterprise Network Modernization

Published by Anar • Infrastructure • Network Design

Network modernization is not only about replacing old switches or access points. It is about understanding business dependency, risk, scalability, supportability, and operational continuity.

> problem

Many enterprise environments grow over years without a clean design. Legacy switches, mixed vendors, unclear VLAN structure, weak documentation, and single points of failure create operational risk.

> approach

  • Audit current topology, racks, switches, access points, uplinks, and VLANs.
  • Identify end-of-life equipment and operational risks.
  • Separate business-critical, guest, security, and management traffic.
  • Prepare high-availability design with clear failover paths.
  • Document everything before implementation.

> result

A good redesign gives the business a more stable, scalable, and supportable network. The goal is not only performance — the goal is predictable operations.

Nginx Reverse Proxy Notes

Published by Anar • Web Server • Infrastructure

A reverse proxy is one of the simplest and most powerful components in a modern web stack. It can route traffic, terminate SSL, protect backend services, and make deployments cleaner.

> common use case

One public server receives traffic on ports 80 and 443, then forwards requests to internal applications running on different ports or containers.

> key benefits

  • Central SSL termination
  • Cleaner internal app exposure
  • Domain-based routing
  • Better logging and troubleshooting

Practical AI Use Cases for Sysadmins

Published by Anar • AI • Automation

AI is not here to replace infrastructure thinking. It is here to remove repetitive work, speed up troubleshooting, and help engineers document and automate better.

> useful areas

  • Log analysis and incident summaries
  • Script generation and review
  • Documentation generation
  • Monitoring alert explanation
  • Operational checklist creation

> mindset

The best sysadmin does not blindly trust AI output. He validates, tests, and turns it into repeatable operational process.
