Platform as a Service
HA Database Service on Kubernetes
Configuration Options : Active-Active / Active-Standby
Supported Databases :
- RDBMS: MySQL, MariaDB, PostgreSQL
- NoSQL: ElasticSearch, MongoDB, Couchbase, Cassandra, Hadoop
Additionally, we support middleware such as RabbitMQ and Kafka,
and offer Redis for caching services.
CI / CD
Streamlining CI/CD with GitLab, Harbor, and ArgoCD
Integrates GitLab, Harbor, and ArgoCD to create a seamless, automated workflow for building, securing, and deploying applications.
Code changes pushed to GitLab are automatically built and tested, container images are securely stored and scanned in Harbor, and deployments are managed and synchronized with ArgoCD.
Logging Service
- EFK Stack Service / Loki Service
- Log analysis for Kubernetes services
- Collection and analysis of application pod logs
- Visualization dashboards provided through Kibana and Grafana
- Basic configuration service; additional features require customization
Monitoring Service
- Prometheus / Grafana Service
- Monitoring and management of resources such as databases, VMs, and containers
- Alarm service configuration available via email and Slack
- Basic configuration service; additional features require customization
Notable QKS Features
Kubernetes High Availability configuration
using HAProxy and VIP Manager
The high availability (HA) Kubernetes control plane setup uses Keepalived and Layer 4 (L4) HAProxy, both deployed as static pods on three control-plane nodes.
Keepalived monitors the health of each node, activating its virtual IP (VIP) on healthy nodes. The L4 HAProxy load balancers route client requests to the active VIP, ensuring continuous access.
If a node fails, Keepalived updates the VIP to another healthy node, and HAProxy redirects traffic, maintaining uninterrupted service. This configuration ensures robust and reliable management of Kubernetes clusters.
QKS Repository - Tailored for Air-gapped Environments
With extensive experience in serving sensitive environments such as government agencies and financial institutions, we offer a specialized QKS Repository designed for these unique conditions.
Our expertise includes installing and operating Kubernetes in
air-gapped environments. Using Ansible, we fully automate the collection of necessary packages, images, and Helm charts.
Users can pull images with commands like 'docker pull' in an offline environment by utilizing our offline Docker registry,
making it feel as seamless as being connected to the internet.
