VAIX - Fault tolerant infrastructure for 24/7 high-load machine learning service

VAIX creates corporate AI-driven solutions that connect a brand’s content and products to relevant users in the e-commerce sphere.

Introduction

Project Background VAIX.ai is an AI start-up creating deeply integrated and powerful AI solutions for B2C businesses, with the vision of transforming e-commerce through personalization. VAIX offers highly customized recommender and classification products that help consumer brands to personalize every communication and offering to a customer. To achieve so far unknown accuracy and relevance of their services, VAIX uses Deep Learning models, which require high amounts of data, GPU-level performance at high availability, and fault tolerance.

VAIX Request Our mission was to build a solution that scales with the needs of the customer in a cost-efficient manner while being secure and fault-tolerant at the same time. It had to function 24/7 despite any technical changes in the system, the data collecting process, or a program crash.

Challenge

To provide a scalable and high-availability infrastructure.

Solution

We managed to create a high-availability infrastructure, using operating principles that our research development team was implementing and testing over two years. This allowed reduced time-to-market, enhanced product reliability, and kept costs at a minimum.

Containerization
Docker
Orchestration
Kubernetes
Orchestration
Rancher
Monitoring Collectors:
  • Telegraf
  • NodeExporter
  • cAdvisor
UI:
  • Grafana
  • Zabbix
CI:
  • Jenkins
  • Gitlab ci
Storage:
  • NFS
  • CEPH
Logging:
  • Datastore: elasticsearch
  • UI: Kibana, Graylog
Load Balancing:
  • AWS Route53
  • NGINX
  • Traefik
In parallel, the customer also checked Google Cloud services and AWS ones, but our custom cloud solution has won this competition.
“The most exciting thing about this project is that we continually made headway considering the implementation of the technology pool. We didn’t just blindly follow trends. Instead, we always looked for the most beneficial and reliable combination of tech approaches. During the VAIX project, we were able to prove one more time, that not technology, but mindful, cooperative teams rule the world.”
