DXP Cloud hosting considerations

This module provides a detailed overview of key considerations for hosting Optimizely solutions in the Optimizely Digital Experience Platform (DXP) Cloud, a fully managed Azure-based environment.

Optimizely DXP Cloud Overview

DXP Cloud abstracts infrastructure management and provides a fully managed environment for CMS and Commerce applications, enabling focus on building digital experiences.

Key Benefits

• Scalability: Automatic scaling for web apps and databases.
• Reliability & High Availability: Redundancy across Azure regions.
• Security: Azure security features, WAF, DDoS protection.
• Managed Services: Patching, updates, operational overhead reduction.
• Integrated CI/CD: Built-in pipelines for deployments.
• Global Reach: Azure CDN for worldwide content delivery.

Architectural Components in DXP Cloud

Optimizely solutions on DXP Cloud utilize multiple Azure services to deliver high-performing and scalable applications.

1. Azure App Service (Web Apps)

• Core Hosting: CMS and Commerce apps run on Azure App Service.
• Multiple Instances: Ensures high availability and load balancing.
• Deployment Slots: Supports zero-downtime deployments.

2. Azure SQL Database

• Managed Database: CMS content, Commerce data, and user info stored here.
• Scaling & Backups: Automatic scaling, backups, and HA.

3. Azure Blob Storage

• Media Storage: Images, videos, and documents.
• CDN Integration: Fast global delivery of media assets.

4. Azure Search (Optimizely Search & Navigation)

• Search Indexing: Hosted on Azure Search / Azure AI Search.

5. Azure Redis Cache

• Distributed Caching: Maintains cache consistency across multiple web app instances.
• Session State: Optional distributed session management.

6. Azure CDN

• Global Content Delivery: Caches static assets at edge locations for fast load times.

Deployment Process in DXP Cloud

DXP Cloud uses Git-based CI/CD pipelines to streamline deployments across Integration, Preproduction, and Production environments.

1. Continuous Integration / Continuous Deployment (CI/CD)

• Automated Builds: Triggered when code is pushed to designated branches (e.g., integration, master).
• Deployment Environments: CI/CD pipelines linked to environment branches.
• Deployment Slots: Stage new versions and swap into production with zero downtime.

2. Environment-Specific Configuration

• appsettings.json Overrides: Use environment-specific files (e.g., appsettings.Preproduction.json).
• Azure App Service Application Settings: Override sensitive settings securely without committing to source control.

Best Practices for Developing for DXP Cloud

• Stateless Web Apps: Avoid storing session state in-memory; use Redis for distributed session state.
• Distributed Caching: Always use IDistributedCache backed by Azure Redis Cache.
• Externalized Configuration: Keep environment-specific settings in Azure App Service or Key Vault.
• Logging & Monitoring: Use structured logging (e.g., Serilog) and integrate with Azure Application Insights.
• Media Handling: Store media in Azure Blob Storage and use CDN caching.
• Database Interactions: Async queries, efficient SQL, and connection resiliency.
• CI/CD & Deployment: Automated tests, deployment slots, and rollback strategy.
