Our projects

Task

Build a refractory platform for deploying applications, as well as translate the entire software development process into modern technologies for the Chocofamily group of companies.

Solution

Our SRE engineers developed several Kubernetes clusters, implemented CI / CD processes for different environments and migrated more than 600 services on new "rails". So they developed CI / CD templates for several programming languages - PHP, Python and others. Organized centralized access to various systems for 450 employees and modernized the system for monitoring digital products.

Implemented technologies:

Task

Completely separate the infrastructure in connection with the separation of the insurance division of Kaspi Bank JSC into a separate entity - Basel Insurance Company JSC

Solution

First of all, our engineers prepared the target infrastructure, deployed the network layer and created the necessary virtual machines on the side of Basel Insurance Company JSC. To communicate with the data center of Kaspi Bank JSC, a temporary communication channel was "raised" and the corresponding routes were registered, which in turn made it possible to complete a phased migration process without denial of service for the end user. During the indicated period of time, we completely separated IP telephony, DBMS and various auxiliary systems. Also, our specialists carried out the modernization of some systems and the implementation of various solutions based on open source.

Implemented technologies:

Proxmox
Nutanix
Cisco
Mikrotik
Fortigate
Asterisk

Task

Implement HA infrastructure for the Halyk Market project. Conduct stress testing and software tuning to handle 10,000 concurrent connections per second.

Solution

To meet the business requirements, we "deployed" a fault-tolerant infrastructure based on Kubernetes in multi-master mode, PostgreSQL from 3 replicas with Patroni "wrapper", as well as GlusterFS distributed file storage. After the basic configuration, we switched to stress testing, thanks to which we got accurate metrics for horizontal scaling and identified all the bottlenecks of the system. At the final stage, our specialists carried out performance tuning with the subsequent transfer of the infrastructure to the customer's specialists.

Implemented technologies:

Kubernetes
PostgreSQL
GlustreFS
Nginx
ELK
InfluxDB
jMeter
Prometheus
Grafana

Task

Conduct an audit of a fleet of physical servers, solve problems with the availability of the application, develop an architecture and offer options for building, testing and delivering the product.

Solution

We have reduced our physical server fleet through the use of cloud computing. As a result of the project migration to the Kubernetes platform, in conjunction with cloud services, it was possible to optimize resource consumption, as well as apply technologies for horizontal automatic scaling. Our engineers implemented the GitOps methodology using solutions from GitLab and deployed a secure VPN server for the centralized work of the client team. As a result, the client was able to reduce infrastructure costs, as well as automate development processes and, as a result, reduce time-to-market.

Implemented technologies:

Openstack
Terraform
Kubernetes
Gitlab CI/CD
PostgreSQL
PHP
GitOps
Proxmox

Task

One of the largest software developers in Kazakhstan, Prime Source, submitted the task of optimizing infrastructure and CI / CD processes.

Solution

Application architecture consisted of microservices developed in java and angular. Practice of CI was partially applied during production, but at the same time, due to huge number of own scripts, many processes depended on the work of one engineer. To solve this issue, we deployed a Kubernetes cluster, created master-slave PostgreSQL replication. Implemented true unified CI for all microservices via Helm. Client now has more testing environments.

Implemented technologies:

Gitlab (CI, registry, gitlab-runner)
Helm v3
Prometheus
Grafana
PostgreSQL
EFK
K8S
Redis
RabbitMQ

Task

Sberbank needed to implement advanced DevOps practices. But the closed low-code solutions used in the company did not allow rebuilding production processes.

Solution

As a result of the infrastructure audit, we decided to create a technology for assembling, testing and delivering products for the client from scratch. For the solution we developed, we also established end-to-end integration between all client systems. We named the resulting product Semaphor and are actively improving it. As a result, Sberbank was able to successfully implement DevOps in its processes.

Implemented technologies:

Jenkins
Jira
BitBucket
Docker
Semaphor
Nexus
HAProxy

Solution

Our engineers have done work on deploying a hybrid infrastructure: Development, Stage environment and development environment on physical servers, Production on Yandex cloud. We prepared the infrastructure and successfully passed the information security audit (PCI DSS). Automated development processes, implemented tools for statistical analysis of code and docker containers for vulnerabilities. Organized a proactive incident response system and implemented a toolkit for monitoring critical metrics.

Task

The infrastructure of the online store is built on simple and proven, but difficult to scale solutions. They limited the ability to grow and manage the infrastructure of the entire project. There was a need for horizontal scaling and optimization of the DBMS.

Solution

To ensure horizontal scalability, a Kubernetes cluster was introduced. The phased migration of the project to the updated architecture ensured successful and more than twofold (in terms of infrastructure) growth of the project, formed the foundation for its further evolution as a scalable solution. Developers received constant advice and tools that simplify the process of delivering applications to production. Numerous and business-critical issues with Elasticsearch, which is actively used in the application, have been resolved.
