Hybrid Cloud Architectures

Introduction

A hybrid cloud architecture combines cloud resources with on-premises infrastructure, often serving as a pilot approach for organizations beginning their cloud migration journey. This document explores various implementation patterns and their characteristics.

Core Principles

Definition and Purpose

• Integrates cloud and on-premises resources

• Serves as a stepping stone for cloud adoption

• Enables flexible resource allocation

• Maintains existing infrastructure investments

Architecture Characteristics

• Loose coupling between components

• Transparent operation across environments

• Scalability across platforms

• Infrastructure flexibility

Implementation Patterns

Pattern 1: Hybrid Storage Solution

Architecture Components

• AWS Storage Gateway

• Local cache at corporate headquarters

• Remote office access points

• S3 backend storage

Key Benefits

• Transparent user experience

• Enhanced data redundancy

• Reliable storage infrastructure

• Cost-effective implementation

• Low-risk deployment approach

Pattern 2: ERP Integration Pattern

Components

• On-premises ERP system

• Middleware integration layer

• Amazon SQS queue

• EC2 worker instances

• DynamoDB database

Data Flow

1. ERP system generates updates

2. Middleware processes and forwards to SQS

3. Worker instances monitor SQS queue

4. Updates processed in DynamoDB

Architecture Benefits

• Loose coupling between systems

• Scalable message processing

• Reliable data synchronization

• Independent component operation

Pattern 3: VMware Hybrid Deployment

Implementation Components

• VMware vCenter

• Cloud provider integration

• vCenter plugin for AWS

• On-premises data center

Operational Features

• Workload distribution flexibility

• Dynamic resource scaling

• Cost-efficient capacity management

• Seamless cloud integration

Best Practices
