As a seasoned System Administrator with 9 years of substantial experience in Linux and Cloud server management, hosting your Node.js and MySQL web application on your Linux VPS with Hostinger is right up my alley. I've designed, configured, and managed public/private cloud infrastructures on Amazon Web Services (AWS), which includes EC2, VPC, Subnets, Security Groups, Domain routing using route tables to ensure optimal performance at all times.
Your urgency is my priority and I can assure you swift delivery while maintaining strict attention to detail. My expertise extends beyond just Linux Server operations. I am proficient in using Ansible and Terraform for swift deployment which will further hasten the setup process. Moreover, I have vast experience with Docker including CI/CD processes which will also benefit your project.
In terms of scalability and traffic handling, during my tenure, I've ensured high availability and balanced loads across multiple instances in different Availability Zones using AWS Elastic Load Balancer (ELB). Combining this specific experience with the use of Portainer to manage the Kubernetes clusters that deploy Docker containers used in Autoscaling architecture is a match made in heaven to your request. You can expect robust server infrastructure that guarantees maximum performance under load while providing easy scalability to handle a large user base when needed. Can't wait to get started!
