Deploy anywhere.
Scale everywhere.
Cloud SaaS, private cloud, on-premise, or hybrid. Standalone, HA, or HADR. Extensible with IoT, GPS, VPN, SSO, MDM. Designed for paper mill IT teams who care about uptime, security, and total cost of ownership.
Deployment Models
Four ways to deploy.
Pick the model that matches your data residency, control, and operating model preferences.
Cloud SaaS
Fully managed multi-tenant SaaS. Zero infrastructure. Auto-scaling, auto-patching, 99.5% SLA. Sign up Monday, transact Friday.
- Hosted on AWS / Azure / GCP
- Mumbai + Hyderabad regions
- Daily backups · 30-day retention
- Auto-scaling 10–2000+ concurrent users
- DDoS protection + WAF
Private Cloud
Dedicated tenant in customer's preferred cloud (AWS, Azure, OCI). Your VPC, your IAM, your audit policies. Data never crosses tenant boundary.
- Customer VPC / VNet hosted
- Single-tenant database
- Region locked per regulation
- Customer-managed encryption keys (BYOK)
- Custom backup + DR policy
On-Premise
Customer datacenter, customer hardware. Air-gapped or VPN-only access. Suited for mills with strict data residency or regulatory mandates.
- Customer hardware + datacenter
- Air-gap or VPN access models
- Customer-managed PKI
- Supported via secure remote tunnel
- Quarterly on-site reviews
Hybrid
API + back-end in cloud, planner UI on-prem (or vice versa). Common for mills running Deckle Optimizer on-prem with reporting in cloud.
- Mixed deployment topology
- Site-to-site VPN connectivity
- Edge cache for shop floor
- Asynchronous data sync
- Custom failover policies
