Deployment & Hosting Flexibility

What Deployment Flexibility Means

Deployment flexibility at Jeeva AI is the capacity to run a single codebase in several topologies—shared-cloud SaaS, logically isolated tenant spaces or fully dedicated VPC footprints—without rewriting software or inventing parallel operational tracks. A composable infrastructure layer, expressed in version-controlled Terraform modules and container charts, lets the same build artifacts target different AWS accounts, regions and network boundaries with no manual re-engineering.

Why It Matters

Regulatory expectations vary widely: some customers are comfortable in a shared environment, while others must satisfy residency mandates, sector rules or private-network requirements. Meeting that spectrum with one provably secure architecture removes friction during procurement and lets customers tighten or relax controls over time. Internally, a uniform deployment model means that backup drills, restoration tests and incident-response runbooks stay identical across footprints, reducing cognitive load when seconds count.

Composable Infrastructure Architecture

Every environment—whether the shared production fleet or a tenant-specific account—spins up from the same signed Terraform plan. The plan declares VPCs, subnets, IAM roles, security groups, service-mesh policies and KMS hierarchies; it will not apply unless a CI job verifies its signature. Network ACLs default to “deny all egress” until domain-based exceptions for email, payments or telemetry are merged and redeployed through the same pipeline.

Multi-Tenant SaaS by Default

The quickest route to value is the shared-cloud service. Data isolation relies on tenant identifiers at the application layer and row-level policies in the database. Each tenant receives its own data-encryption key, rotated on a fixed schedule or after privilege-boundary changes. Because all tenants share the fleet, updates roll out with zero downtime—containers drain, relaunch and health-check across multiple Availability Zones before traffic shifts.

Dedicated VPC Option

When a stricter posture is required, the identical blueprint targets a fresh AWS account under Jeeva AI’s organisation. Compute, storage and KMS keys become single-tenant, and ingress can arrive over AWS PrivateLink so traffic never touches the public internet. Central observability and patch automation operate through cross-account roles, preserving separation of duties without console access.

Regional Residency Controls

Blueprint variables include region selection and optional intra-region replication. A customer in the EEA can pin primary storage to eu-central-1 and replicate asynchronously to eu-west-1. Backup snapshots honour the same region filter, aligning with local-storage rules and avoiding unintended transfers. If the legal landscape changes, the cross-border-transfer procedure switches to approved mechanisms such as Standard Contractual Clauses while encryption settings remain untouched.

Shared Continuity and Recovery Playbook

Each footprint inherits the same resilience routines. Daily logical database backups—encrypted with tenant keys—land in a cross-region vault, and periodic restore drills rehydrate those backups in an isolated test VPC to check integrity. The disaster-recovery plan rehearsed annually recreates the entire stack in a standby region and validates that internal recovery objectives are met. Findings feed the risk-assessment register and are made available to customers on request.

Aligned Change-Management Path

Application and infrastructure changes follow one lattice: feature branch, peer review, automated tests, licence scan, security scan, signed image and controlled rollout. Infrastructure updates—new load-balancer rules or outbound exceptions—attach their Terraform diff to the merge request and require an explicit infrastructure sign-off label before merging. A single path keeps application velocity and infrastructure safety in sync.

Governed Migration Path

Tenants can begin in the shared tier and later request isolation. A migration orchestrator exports data, re-encrypts it under the new key hierarchy, provisions the dedicated stack and replays audit logs to maintain continuity. Cut-over happens during an agreed window, and DNS aliases move atomically so end-users experience only a brief read-only banner. Because the process leverages the same tooling used for routine backup restores, no bespoke scripts are required.

Unified Monitoring and Supplier Oversight

Regardless of footprint, logs, metrics and events stream into a central observability account via cross-account subscriptions. Alert rules, paging rotations and compliance dashboards remain consistent, while service wrappers expose per-tenant consumption of third-party providers such as email or telephony so that capacity or commercial terms can be adjusted proactively.

Outcome

The result is a hosting model that bends to regulatory or architectural preference without splintering the release train. Customers can adopt stricter controls as governance matures—or relax them when agility takes priority—confident that resilience, security and observability remain constant at every turn.
