Oracle Cloud Infrastructure
The cloud layer that makes Oracle SaaS extensible.
OCI architecture for the workloads that live around Fusion: Autonomous Database, Functions, API Gateway, Object Storage, networking, identity and observability, designed for security and high availability.

Overview
Oracle OCI, done properly.
Fusion applications are closed by design. OCI is where the rest of the solution lives: the staging database for integrations, the API that a mobile app calls, the function that transforms a partner file, the storage that holds seven years of documents. AMTEX designs and runs that layer.

What we deliver
Capabilities
Everything AMTEX builds, configures and runs across Oracle OCI.
OCI architecture
Compartments, tenancy design, landing zones and Terraform so every environment is reproducible.
Autonomous Database
ATP and ADW for integration staging, application data, APEX and analytics, with private endpoints and Data Safe.
Object Storage
Lifecycle-managed buckets for files, archives and report distribution, with pre-authenticated requests where appropriate.
API Gateway
Authentication, rate limiting, request validation and routing in front of OIC, Functions and backend services.
Functions
Serverless code for transforms and glue that OIC should not do in-line, in Node.js, Python or Java.
Notifications, Queue & Events
Alerting and decoupling patterns: Events to Functions, Queue for buffering, Notifications to people.
Networking
VCNs, private endpoints, FastConnect or VPN to on-prem, and the connectivity agent design for OIC.
Identity
Identity domains, federation with Entra ID or Okta, policies written for least privilege.
Monitoring & logging
Logging, Monitoring, alarms and dashboards that cover OIC, Functions and databases in one place.
High availability & DR
Multi-AD designs, Autonomous Data Guard and tested recovery procedures.
Security
Cloud Guard, Vault, Security Zones, WAF and a posture review against the CIS OCI benchmark.
Cloud modernisation
Moving on-prem Oracle databases and applications to OCI, including EBS on OCI.
The hard parts
Where these projects become difficult
The places programmes slip, and what we do about each one.
- 01
Hand-built tenancies
The problem
Nobody can rebuild the environment, and nobody is sure what the policies allow.
How AMTEX approaches it
Terraform for everything, a policy review and a landing-zone pattern applied retroactively.
- 02
Integration sprawl
The problem
OIC does everything, including things it is slow and expensive at.
How AMTEX approaches it
Move heavy transforms to Functions, staging to ATP, files to Object Storage, and let OIC orchestrate.
- 03
Cost visibility
The problem
The bill grows and nobody knows which workload caused it.
How AMTEX approaches it
Tagging standards, budgets and alarms, and right-sizing reviews.
Pattern
Event-driven, not polled.
The pattern we use when downstream systems need to react to Fusion in near real time without hammering its APIs.
- Fusion raises the event; OIC subscribes and validates once.
- A queue or stream decouples producers from consumers, so a slow consumer never blocks Fusion.
- Consumers are Functions, applications behind API Gateway, or warehouse loads, each scaling independently.
- Every hop is logged with the business identifier so a single invoice can be traced end to end.
Trigger
- Fusion business evente.g. Invoice approved

How we work
From first conversation to steady state
01
Assess
Workloads, security posture, cost, connectivity.
02
Design
Landing zone, network, identity, service selection.
03
Build
Terraform, pipelines, workloads, observability.
04
Operate
Monitoring, patching, cost management, DR tests.
