Overview: FlexSite vs Acquia at a glance
Acquia’s Drupal Cloud and Cloud Platform focus on large enterprises, with Varnish-based reverse proxy caching, Memcached for application caching, and a global CDN available across its tiers, plus advanced enterprise caching options. Environments and resources scale with plan size and enterprise agreements.
FlexSite targets teams that want the same caliber of performance but without complex packaging: Varnish, Redis, and CloudFront CDN are included on every plan, environments are fully flexible (pay only for what you use), and AI assistance, deployment visibility, site alerts, advisories, and mobile app are built into the platform.
Feature comparison: caching, CDN, and environments
| Capability | Acquia | FlexSite |
|---|---|---|
| Varnish cache | Reverse proxy caching included on Cloud Platform; advanced enterprise caching options available on higher tiers. | Included in all plans. |
| Redis | Not offered as a managed cache service; Memcached is the standard external cache backend. | Included in all plans. |
| CDN | Platform CDN included across tiers; advanced CDN options and SLAs on higher plans. | Included in all plans (CloudFront). |
| Multi-environment | Three core environments (Dev, Stage, Prod) with additional environments available on higher/enterprise tiers. | Fully flexible—add or remove when needed, name as you like, pay only for what you use. |
| Deployment visibility | Varies by tier; not always end-to-end. | See what happens from code push until changes are ready on the environment. |
| Site Alerts | Monitoring available; proactive alerts vary by plan. | Proactive monitoring to detect errors and notify you. |
| Configuration Advisories | Not typically offered. | Per-environment recommendations to get the best from your sites. |
| Mobile app | Not typically offered. | Receive project alerts and talk with Flexy for project status whenever and wherever. |
| Built-in AI | Acquia AI and related agents for content, governance, and experience (separate AI services). | Flexy AI included. |
Built-in performance stack
Acquia offers robust performance tooling, but some capabilities—such as advanced caching tiers and higher CDN SLAs—are associated with specific enterprise-oriented packages. Memcached is the default application cache, and Redis is not provided as a managed cache service.
FlexSite aligns with teams that want a pre-integrated performance baseline: Varnish for HTTP caching, Redis for high-throughput application caching, and CloudFront CDN included on every plan. You do not need to navigate add-ons or enterprise SKUs simply to standardize on Redis and CDN-backed performance.
Flexible environments
Acquia Cloud applications typically ship with three primary environments (Dev, Stage, Prod) and allow additional environments based on plan and enterprise agreements. This covers many workflows but can introduce constraints when many parallel workstreams or client variations must coexist.
FlexSite environments are fully flexible: you decide when to add or remove one, name them as you want, and pay only for what you use. Short-lived environments are supported without fixed counts—especially valuable for agencies and product teams managing multiple Drupal sites.
AI-assisted platform
Acquia has invested significantly in AI, with offerings such as Acquia AI, AI agents for content and web governance, and AI providers for Drupal. These tools focus on content creation, site governance, analytics, and experience optimization.
FlexSite’s Flexy AI is positioned differently. It is integrated into the hosting platform and modern Drupal workflow, focused on developer and DevOps tasks such as configuration assistance, deployment guidance, and performance considerations.
Deployment visibility, site alerts, configuration advisories, and mobile app
FlexSite provides deployment visibility from code push until changes are ready on the environment, proactive site alerts to detect errors and notify you, per-environment configuration advisories to get the best from your sites, and a mobile app to receive project alerts and talk with Flexy for project status whenever and wherever.
Migrating from Acquia to FlexSite
Moving from Acquia to FlexSite typically involves exporting code, databases, and files from Acquia; rehydrating the application on FlexSite with Varnish, Redis, and CloudFront activated by default; and recreating environment workflows with flexible non-production (add, remove, name as you need—pay only for what you use) environments as needed. FlexSite can assist with migration planning, performance validation, and ensuring that critical caching headers and CDN behaviors remain aligned.
