Governed Cloud Platform for Standardized Infrastructure Provisioning of Enterprise Data Warehouse Applications

Description

This project is about building a Governed Cloud Platform that provides a standardized and controlled way to provision cloud infrastructure for Enterprise Data Warehouse Applications. Instead of manually creating servers, networks, storage, and security settings, the platform automatically provides approved infrastructure environments while following organizational governance and security standards. The provisioned infrastructure supports data warehouse applications that store and organize enterprise data for reporting, analytics, and business intelligence.

04

Stage 4. Validate Data Quality

Process

The transformed data is checked to ensure that it is accurate and complete.

Tools
Python
Implementation

The application performs validation checks to identify missing values, duplicate records, incorrect formats, and other data-quality problems.

05

Stage 5. Load Data into the Enterprise Data Warehouse

Process

The validated and transformed data is loaded into the central Enterprise Data Warehouse.

Tools
PostgreSQL
Implementation

The processed enterprise data is stored in structured tables inside the data warehouse for long-term storage and analysis.

06

Stage 6. Organize and Manage Warehouse Data

Process

The stored data is organized to support efficient querying and analysis.

Tools
PostgreSQL
Implementation

The data warehouse organizes enterprise data into structured tables and relationships so users can efficiently access the required information.

07

Stage 7. Generate Reports and Analytics

Process

The stored enterprise data is analyzed to generate reports and business insights.

Tools
Apache Superset
Implementation

Business users and analysts create reports, charts, and dashboards to analyze sales, finance, customers, inventory, and other business information.

08

Stage 8. Support Business Decision Making

Process

Business insights are provided to managers and decision-makers.

Tools
Apache Superset
Implementation

The application presents business performance information through dashboards and reports, helping management make informed decisions.

Cloud Infrastructure and Tools

Infrastructure-as-Code Orchestrator OpenTofu

Creates and manages cloud infrastructure such as compute, networking, storage, and security resources using infrastructure configuration files instead of manual cloud-console configuration.

Policy Enforcement Engine Open Policy Agent (OPA)

Evaluates infrastructure configurations or plans against predefined security and governance policies and can prevent non-compliant infrastructure from being deployed.

Infrastructure Configuration Manager Terragrunt

Organizes OpenTofu configurations for different environments such as Development, Staging, and Production while reducing repeated configuration.

Command-Line Cloud Management Tool Cloud CLI

Allows engineers to interact with Cloud from the command line to configure resources, verify settings, and perform administrative operations.

Compute Platform Cloud EC2 Instances

Provides virtual servers for running the Enterprise Data Warehouse Application and its supporting workloads.

Server Operating System Ubuntu Server 24.04 LTS

Provides the Linux operating system for EC2 servers running the application and supporting services.

Target Cloud Networking Plane Cloud VPC

Provides the private cloud network for the Data Warehouse Application and separates public-facing access from private application and data resources.

Security Controls & Firewalls Cloud Security Groups + Network ACLs

Control network traffic to and between cloud resources and help protect the Data Warehouse environment from unauthorized access.

Target Cloud Storage Cloud S3

Provides object storage for files such as data exports, backups, logs, and other data-warehouse-related objects.

IaC State Storage & Locking Cloud S3 + DynamoDB

S3 stores the OpenTofu state remotely, while DynamoDB can provide state locking for OpenTofu workflows where supported/configured, helping prevent conflicting infrastructure operations.

Implementation Process

01
Step 1 – Define Infrastructure Standards and Governance
  • Review the infrastructure requirements of the Enterprise Data Warehouse Application.
  • Identify the required compute, networking, storage, and security resources.
  • Define standard configurations for Development, Staging, and Production environments.
  • Define security, compliance, naming, tagging, and access-control requirements.
  • Create governance policies that infrastructure must follow before deployment.
02
Step 2 – Create Infrastructure-as-Code Templates
  • Create reusable OpenTofu configuration files for the required cloud resources.
  • Define EC2, VPC, security groups, EBS, and S3 configurations.
  • Use variables to support different environment requirements.
  • Use Terragrunt to organize and manage configurations for each environment.
  • Store the infrastructure code in a version-controlled Git repository.
03
Step 3 – Implement Governance and Validation
  • Define Open Policy Agent (OPA) rules for security and infrastructure compliance.
  • Validate OpenTofu configurations against the defined governance policies.
  • Check resources for required security settings, tags, network restrictions, and approved configurations.
  • Reject infrastructure plans that violate mandatory governance rules.
  • Approve compliant infrastructure configurations for deployment.
04
Step 4 – Provision the Cloud Infrastructure
  • Use OpenTofu to create the approved Cloud infrastructure automatically.
  • Create the Cloud VPC, subnets, EC2 instances, security groups, and EBS storage.
  • Configure Ubuntu Server 24.04 LTS on the EC2 instances.
  • Configure Cloud S3 for required application data, backups, or files.
  • Store OpenTofu state remotely using Cloud S3 with state locking configured through the selected backend mechanism.
05
Step 5 – Deploy and Validate the Data Warehouse Environment
  • Install and configure the Enterprise Data Warehouse Application on the provisioned infrastructure.
  • Configure connectivity between the application, data sources, storage, and required services.
  • Verify network connectivity, security controls, storage, and application functionality.
  • Test the environment using sample enterprise data and basic warehouse operations.
  • Monitor the infrastructure and maintain the environment according to the defined governance standards.

Proposed Solution

The proposed solution provides a Governed Cloud Platform that automates and standardizes the infrastructure provisioning required for Enterprise Data Warehouse Applications. The platform uses predefined infrastructure configurations and governance policies to provision compute, networking, storage, and security resources consistently across Development, Staging, and Production environments. This reduces manual configuration and ensures that infrastructure follows organizational security and compliance standards.

Benefits

Standardized Infrastructure: Provides consistent infrastructure configurations across environments.
Automated Provisioning: Reduces manual effort when creating cloud resources.
Governance & Compliance: Ensures infrastructure follows predefined security and organizational policies.
Faster Deployment: Reusable configurations reduce the time required to provision new environments.
Reduced Configuration Errors: Automated infrastructure reduces mistakes caused by manual configuration.
