Scalability
This section describes how to scale solution based on Virto Commerce platform and Virto Commerce Storefront Kit.
S: Small
The small environment is good for simple projects, proof of concept, etc.
Key elements: 1. 1x Storefront Instance 2. 1x Backend Instance
M: Medium
Ready for production and scalability. You can go live with MVP.
Key elements: 1. Multiple Storefront Instances 2. Multiple Backend Instances 3. Redis Cache as Distributed Cache Storage
L: Large
Good for the complex solution and provides ability use benefits of modern Azure service and Virto Commerce.
Key elements: 1. SQL Database Elastic Pool (Split modules by different DB: Cart, Order, Catalog, Customers, etc.) 2. AzureSearch or Elasticsearch cluster
XL: Extra Large
You can decrease resource utilization and cost by splitting admin by functional elements. Minimize performance degradations from different processes (Ex: Background Jobs to Storefront and Content Managers).
Note: The environment is very close to multiple regions solutions and helps to achieve high availability and high performance.
- VC backend environment for Storefront App (no Background Jobs)
- VC backend environment for Content Managers (no Background Jobs)
- VC backend environment for Background Jobs (focus on high CPU utilization)
