Vsi. Svoi — Modernizing E-commerce Infrastructure with Kubernetes

Task: Scalability and Infrastructure Reliability

The client asked us to improve the project infrastructure and provide the opportunity to add new sections to the site. Stfalcon's task was to move to a containerized infrastructure with Kubernetes:

• increase the overall reliability of the infrastructure and the percentage of service availability,
• simplify the process of making changes, ensure the identity of dev/staging/production environments,
• speed up and secure the process of delivering changes to environments.

Also, one more task was to add new sections: Home and Decor

Solution: Cloud-Native Approach with Kubernetes & IaC

When building new infrastructure, IaaS Hetzner Cloud was chosen, which combines a favorable cost and high quality of services provided, and also has all the basic functionality required to build a modern and flexible infrastructure.

It was decided to use containerization since this approach simplifies further maintenance and allows you to increase the frequency of releases, simplify horizontal scaling, and ensure the identity of the configuration in environments. The orchestrator was Kubernetes, an industry-standard that incorporates Google's many years of experience in serving containerized workloads.

When deploying the new infrastructure, Terraform was also used, which allows implementing the concept of Infrastructure as Code (IaC). This made it possible to simplify making changes and fully automate the addition of new nodes to the Kubernetes cluster. Also, Continuous delivery was configured for all applications using Gitlab CI/CD.
