FORRUN

Challenges

Forrun application runs on LEMP stack (Linux, Nginx, MySQL, and PHP). Initially, the Arpatech team set- up Forrun’s application on some on-premise servers in at their own data center. As time passed, Arpatech faced an overwhelming response from the customers and clients. This was due to the fact that Forrun provided quicker, safer, and more convenient delivery services across Pakistan.

The Arpatech team uses Amazon VPC (Virtual Private Cloud), Amazon EC2 (Elastic Compute Cloud), Amazon ELB (Elastic Load Balancing), and Amazon ASG (Auto-Scaling Groups). AWS auto-scaling group scales up the infrastructure and application automatically in peak times and scales down when there is no such load on the servers, so there is no cost of extra compute resources. This is the advantage of AWS Auto-Scaling.

AWS also makes it easy to deploy frequently for new enhancements ot hotfixes. There is no down-time thanks to AWS Rolling Deployment. A rolling deployment updates an application on a stack's online application server instances in multiple phases. With each phase, AWS updates a subset of the online instances and verifies that the update is successful before starting the next phase. If AWS encounters problems, the instances that are still running the old app version can continue to handle incoming traffic until we resolve the issues.
