DevOps Expert for Server Optimization

@ArchnaAdmin

Hi, I have 8+ years of experience as a System Administrator with hands-on expertise in setting up and managing Linux web hosting and cloud servers, including server security, monitoring, and performance optimization. I work with Apache, Nginx, DNS, SSL, Cloudflare configuration and hosting panels such as cPanel/WHM, Plesk, and Virtualmin, and I also handle email server setup and email marketing environments. I provide complete server deployment along with SSL installation (free or paid), including HTTPS configuration and final verification to ensure everything works smoothly. Please discuss your requirements so we can get started. Thank you

Hi, Reviewed your setup carefully. Cloudflare → 1GB VPS proxy → 64GB dedicated is the right architecture for hiding your real IP and absorbing DDoS before it hits your main server. My Approach: 1. Audit: OLS worker config, PHP-FPM pool sizing, MySQL slow query log, Redis hit rate on live server 2. Proxy Layer: Nginx on VPS as entry, main server firewalled to accept only Cloudflare + VPS IPs — real IP fully hidden 3. Cloudflare: WAF rules, rate limiting, bot protection, cache rules for Laravel static assets 4. Tune: PHP-FPM pm.max_children, MySQL innodb_buffer_pool_size, Redis object caching for Laravel sessions/queries, Brotli compression 5. Harden: CSF/Fail2ban on both servers, SSH key-only auth, CyberPanel hardening 6. Test: k6 load test post-config to verify 50k+ CCU stability before handoff Relevant Experience: - Linux production server management (Ubuntu/CentOS), systemd, SSH hardening - Laravel infrastructure deployment with reverse proxy and monitoring - Multi-server distributed setups with full security hardening One question: Is MySQL co-located with OpenLiteSpeed or on a separate instance? This significantly affects the tuning plan. Timeline: 3-4 days | Available immediately.

As a seasoned DevOps engineer and a professional Full-Stack and Flutter Developer, I offer the perfect blend of skills that your project is requesting. Notably, I have significant experience in optimizing live high-traffic servers and handling over 50,000 concurrent users - your project’s key requirement. I've also worked extensively with Cloudflare setups and have a deep understanding of how to configure them for optimal performance and security — from WAF rules to mitigating DDoS attacks. My thorough knowledge of CyberPanel (and OpenLiteSpeed) that your website is already running on would undeniably expedite the optimization and scaling process. Furthermore, my background in PHP enables me to effectively conduct PHP-FPM tuning as well as MySQL/MariaDB optimization; both crucial to your project's success. The inclusion of $(NVMe) storage solution for your dedicated server aligns with my preferences for fast, reliable storage allocation which ultimately translates to better performance.

Hi, I've optimized multiple high-traffic Laravel sites on CyberPanel handling 100k+ concurrent users. Your Cloudflare → VPS → Main Server architecture is proven and I've implemented it successfully. My Approach: Performance: OpenLiteSpeed tuning + PHP-FPM optimization MySQL query optimization + Redis caching Gzip/Brotli compression + static asset caching Target: sub-second load times at 50k users Cloudflare: DNS proxying to hide origin IP WAF with OWASP rules + rate limiting DDoS protection + bot mitigation Cache rules for maximum hit ratio Security: 1GB VPS as reverse proxy (HAProxy) Main server accepts traffic ONLY from VPS CSF firewall + Fail2ban on both servers Real IP fully masked Testing: K6 load testing simulating 50k concurrent users Before/after performance audit Recent Similar Projects: EdTech platform: 80k concurrent exam traffic Gaming site: 120k concurrent, zero downtime Deliverables include full documentation and load test report. Ready to start immediately.
