Why do CPU and RAM sizing matter for Umbraco hosting?
Umbraco runs on ASP.NET Core with a SQL database. The CPU handles request processing, Razor view rendering and background jobs, while RAM powers caching and simultaneous connections.
Incorrect sizing causes:
- Under-provisioning: Slow response times, timeouts and instability under load.
- Over-provisioning: Unnecessary cost without performance gains.
Proper CPU/RAM planning ensures consistent performance, cost efficiency and a platform that can grow with demand.
How to plan resources for an Umbraco site
Resource planning is based on:
- Traffic patterns: Average and peak concurrent users.
- Content structure: Number of pages, nested content and caching efficiency.
- Integrations: API calls, external data and background processing.
- Media usage: Size and frequency of media library calls.
Typical benchmarks:
- Small marketing site: 2 vCPUs / 4 GB RAM.
- Mid-sized corporate site: 4 vCPUs / 8 GB RAM.
- Enterprise/global platform: 8–16 vCPU / 16–32 GB RAM with SQL elastic pools.
Azure Umbraco hosting vs Umbraco Cloud resource allocation
Growcreate configures CPU and RAM allocation in both Azure Umbraco hosting and Umbraco Cloud environments.
Feature comparison
| Attribute | Azure Umbraco Hosting | Umbraco Cloud |
|---|---|---|
| CPU/RAM control | Fully configurable, elastic scaling per instance | Fixed plan sizes with standard resource allocation |
| Auto-scaling | Dynamic based on load or schedules | Automatic scaling within plan boundaries |
| Performance tuning | Granular control for caching, queries and background jobs | Pre-optimised for standard Umbraco workloads |
| Cost efficiency | Pay-as-you-scale with reserved instance discounts | Fixed monthly cost with predictable budget |
Real-world scenarios
1. Sizing for a campaign-driven platform
A retailer running frequent campaigns sized Azure App Services for 2 vCPU/4 GB RAM with auto-scale to 8 vCPU/16 GB during peak demand. Result: Stable performance with 35% lower cost compared to fixed overprovisioning.
2. Scaling a global enterprise platform
A multi-region corporate Umbraco site with heavy API usage utilised 16 vCPUs/32 GB RAM with SQL elastic pools. Fine-grained tuning delivered sub-second response times globally.
3. Umbraco Cloud for predictable workloads
A mid-sized B2B site with stable traffic ran on Umbraco Cloud's fixed plan, without requiring elastic scaling, and benefited from a predictable monthly cost.
ROI and operational impact
| Business Factor | Azure Umbraco Hosting | Umbraco Cloud |
|---|---|---|
| Cost control | Match resources to real demand to avoid overspend | Fixed subscription simplifies budgeting |
| Performance stability | Elastic CPU/RAM ensures consistent speed under load | Pre-optimised plans deliver stable performance |
| Scalability | Ideal for unpredictable or growing traffic patterns | Suitable for predictable workloads |
| Operational workload | Requires planning or managed service | Fully managed resource allocation reduces team input |
