Business Challenge 

For developing the new portal, Tremend employed advanced technologies to solve some complex problems regarding the integration of the online Carrefour systems and the offline ones created for taking the orders and preparing them in the hypermarkets.

 
Solution delivered by Tremend 

Dedicated Scrum teams have designed and built the solution to integrate all the independent projects (carrefour-online.ro, tex.carrefour.ro, lumea-carrefour.ro and carrefour.ro - the corporate website) under the unique portal carrefour.ro, with two main technical components:

  • The Marketplace system - based on Magento 2 with Elasticsearch and Redis

  • The unified service - developed from scratch on top of Symfony, for cart & checkout.

Migration to GCP:

  • Provisioning & configuration management: Terraform, Ansible
  • Highly available, multi-zone deployment
  • Deployment: Kubernetes (GKE), Compute Engine, LB, CloudSQL, Memorystore
  • CI / CD: Bitbucket, Bamboo
  • Monitoring: Prometheus, NewRelic, Nagios, ELK
     

Performance tests ensured the solution would deliver the intended traffic requirements. Security penetration testing made sure the solution can be safely launched.

Results 

Tremend delivered a complex architecture based on Magento2 that allowed Carrefour to catch up on a mature market segment.

The development was a big challenge from the scalability and total accessibility point of view. It reunites tens of Carrefour partners, over 150.000 SKU and an ever-growing number of end users. The products ordered online can be delivered anywhere in the country or picked up in any Click & Collect point in the Carrefour hypermarkets. This is a first for a FMCG retailer.
