Infrastructure Requirements for Private Cloud Deployment

For Large Enterprise customers, K-LINK offers flexible deployment options on GCP, AWS, or customer-managed private cloud environments.

We support:

• Local Compliance: Data residency alignment (PDPA, GDPR, HIPAA, etc.)

• High Availability: Multi-zone deployment, database replication, and failover

• Data Security: End-to-end encryption, daily backups, and 30-day retention

• Private Cloud Ready: On-premise/VPC deployment with zero external dependencies

• Enterprise Integrations: SSO, private networking, and secure configuration options

This deployment model is tailored for enterprise clients with strict regulatory, infrastructure, and security requirements.

Our team works closely with your IT to ensure a smooth and secure setup from infra to production

To ensure optimal performance, scalability, and reliability, we recommend deploying the klink.cloud platform on Google Cloud Platform (GCP) or Amazon Web Services (AWS). However, klink.cloud also supports deployment in customer-managed private cloud environments, provided the following minimum infrastructure specifications are met.
