Cloud architecture

AZTANDC LLC designs the cloud and delivery architecture behind websites and applications: where they are hosted, how traffic reaches them, how they are protected, and how we know they are available. We combine Microsoft Azure and Cloudflare with practical hosting for WordPress and custom applications, so the infrastructure fits the site and the way the business uses it.

Azure gives organizations room to grow without rebuilding their platform. We plan environments around the application’s real requirements for availability, traffic, data, and budget.

• Azure hosting architecture for websites, applications, APIs, and databases
• Azure Front Door and Application Gateway configuration with Web Application Firewall (WAF) policies
• Azure SQL and storage planning, including database sizing and cost considerations
• Separate development, staging, and production environments
• Azure Monitor and Log Analytics for logging, diagnostics, and alerting
• WAF log analysis to find out why legitimate requests are blocked, and to tune rules without weakening protection (see how to find why a request was blocked)

Placing a site behind an edge network can improve speed and reduce exposure before requests reach your servers. We configure Cloudflare to match how the site actually works, including forms, APIs, logins, and integrations.

• DNS configuration and documentation of important records and service dependencies
• CDN and caching rules that speed up delivery without serving stale or private content
• WAF and bot controls with exclusions for legitimate REST, webhook, payment, and CRM traffic
• DDoS protection and TLS/HTTPS enforcement
• Origin protection so the hosting server accepts traffic only from approved sources

Different applications need different hosting. We evaluate shared, VPS, managed WordPress, and cloud options, and recommend the one that fits the site’s traffic, integrations, security needs, and support model. Our approach is outlined in WordPress Security Isn’t One-Size-Fits-All.

• Hosting recommendations and migrations for WordPress, WooCommerce, and custom PHP applications
• Headless and API-driven architectures, including CORS and token considerations
• Staging workflows for testing plugin, caching, and firewall changes before production
• Backup and rollback planning for releases

A site that is down, slow, or broken in one region is a problem for the people trying to use it. We set up monitoring so issues are found early and the right people are notified.

• Website and application uptime monitoring
• SSL certificate and domain-expiration monitoring where supported
• Monitoring of public forms and other critical functions
• Performance and availability alerts with clear escalation procedures

Serving visitors in more than one market takes planning. We design environments for multi-region delivery, including projects that involve China-based infrastructure and Azure China. Regional hosting, privacy requirements, and performance for local visitors are considered together. See our international and accessibility services for related work.
