Black Friday can be a great opportunity to boost sales, but it can also be a huge risk if your platform isn’t prepared. The sudden surge in traffic, simultaneous transactions, and user expectations put every part of your system to the test. If something goes wrong, the consequences can be costly: outages, slowness, payment errors, and a damaged reputation.<\/p>\n\n\n\n
With a thorough review and the right adjustments, your business can come out stronger, offer an unbeatable experience, and make the most of this spike in demand.<\/p>\n\n\n\n
Below, we share a checklist of key practices to ensure your infrastructure is ready for smooth operations.<\/p>\n\n\n\n
Server capacity assessment:<\/strong><\/p>\n\n\n\n \u25a1 Check the average CPU, RAM and storage usage.<\/p>\n\n\n\n \u25a1 Check the current maximum capacity against historical traffic peaks.<\/p>\n\n\n\n Load tests<\/strong>:<\/strong><\/p>\n\n\n\n \u25a1 Use tools to simulate massive traffic.<\/p>\n\n\n\n \u25a1 Identify failure or slowness points.<\/p>\n\n\n\n Resource scalability:<\/strong><\/p>\n\n\n\n \u25a1 Confirm whether your infrastructure can scale vertically (more resources per server) or horizontally (more servers).<\/p>\n\n\n\n Web server configurations:<\/strong><\/p>\n\n\n\n \u25a1 Configure your web servers to handle multiple concurrent connections.<\/p>\n\n\n\n \u25a1 Use caching systems intelligently to avoid overloading the server and databases.<\/p>\n\n\n\n Load balancing:<\/strong><\/p>\n\n\n\n \u25a1 Set up a load balancer to distribute traffic across multiple servers.<\/p>\n\n\n\n \u25a1 Use the load balancing tools offered by your provider.<\/p>\n\n\n\n Databases:<\/strong><\/p>\n\n\n\n \u25a1 Optimizes SQL queries (indexing, denormalization if necessary).<\/p>\n\n\n\n \u25a1 Use cache for frequent queries (Redis, Memcached).<\/p>\n\n\n\n Static storage:<\/strong><\/p>\n\n\n\n \u25a1 Serve images, scripts, and style sheets from a CDN.<\/p>\n\n\n\n \u25a1 Use compression to reduce the size of files sent to the client.<\/p>\n\n\n\n \u25a1 Optimize your images with modern and compressed formats: technologies like on-the-fly optimizers can help you do this easily.<\/p>\n\n\n\n \u25a1 Set up servers in multiple regions or at least in different availability zones (AZs).<\/p>\n\n\n\n \u25a1 Use databases with real-time replication.<\/p>\n\n\n\n \u25a1 Monitor in real time with tools that allow you to measure performance.<\/p>\n\n\n\n \u25a1 Set up automatic alerts for resource issues.<\/p>\n\n\n\n DDoS Protection:<\/strong><\/p>\n\n\n\n \u25a1 Hire mitigation services.<\/p>\n\n\n\n \u25a1 Set up rules on your firewall to block suspicious patterns.<\/p>\n\n\n\n \u25a1 Set a rate limit that doesn’t block legitimate users and keeps your site secure and operational at all times.<\/p>\n\n\n\n SSL\/TLS:<\/strong><\/p>\n\n\n\n \u25a1 Make sure your site uses HTTPS with updated certificates.<\/p>\n\n\n\n \u25a1 Set up HSTS (Strict-Transport-Security).<\/p>\n\n\n\n Authentication and access:<\/strong><\/p>\n\n\n\n \u25a1 Implement robust authentication systems for your admins (2FA, IP Whitelisting).<\/p>\n\n\n\n \u25a1 Perform permit audits.<\/p>\n\n\n\n User Experience (UX) improvements:<\/strong><\/p>\n\n\n\n \u25a1 Optimizes loading times (less than three seconds).<\/p>\n\n\n\n \u25a1 Use Lazy Loading for images and non-critical content.<\/p>\n\n\n\n Payment gateway validation:<\/strong><\/p>\n\n\n\n \u25a1 Perform load testing on integrations with payment platforms.<\/p>\n\n\n\n \u25a1 Make sure they support multiple transactions per second.<\/p>\n\n\n\n Real-time inventory management:<\/strong><\/p>\n\n\n\n \u25a1 Implement systems that update stock in real time to avoid overselling.<\/p>\n\n\n\n \u25a1 Traffic spike testing: conduct simulations with your team to evaluate response and recovery times.<\/p>\n\n\n\n \u25a1 Run a load test: it’s critical to know what we can handle.<\/p>\n\n\n\n \u25a1 Failure scenarios to be prepared for any technical incident.<\/p>\n\n\n\n \u25a1 Design a contingency plan that allows you to react quickly in the event of site outages or performance issues. This plan should include specific actions to mitigate the impact.<\/p>\n\n\n\n \u25a1 Document escalation and recovery procedures so the technical team can act quickly and effectively.<\/p>\n\n\n\n \u25a1 Define who should be contacted for different incident levels and how to proceed in each case to minimize downtime and ensure rapid service recovery.<\/p>\n\n\n\n2.
