Introduction The sizing requirements of the OneFirewall Alliance solution, depending on the Service Level Agreement (SLA) and the log throughput, are summarized in the following table: | OFA Type | Size | SLA | Capability | License | | :-------------------------- | :----------------------------------------------------------------------------------------- | :--------------------------- | :-------------------------------------------------------------------------------- | :-------------------- | | **P-Micro (Collaudo/Test)** | 8 vCPU / 24–32 GB RAM / 300 GB SSD | 99% (No High Availability) | 1 Tenant, no backup, 100–300 log/s, Non-scalable | Trial License | | **P-0** | 8 vCPU / 32 GB RAM / 30GB node + 1000 GB SSD (persistent volume/standard-rwo) | 99.9% (No High Availability) | 1 Tenant, up to 10 users per tenant, daily backup, 100–300 log/s, Non-scalable | Single Tenant License | | **P-1** | 3× 8 vCPU / 3× 32 GB RAM / 30GB node + 3× 1000 GB SSD (persistent volume/standard-rwo) | 99.999% (High Availability) | 2–6 Tenants, up to 15 users per tenant, daily backup, 300–700 log/s, Non-scalable | Single Tenant License | | **P-2** | 3–5× 8 vCPU / 3–5× 32 GB RAM / 30GB node + 3× 1000 GB SSD (persistent volume/standard-rwo) | 99.9999% (High Availability) | 7+ Tenants, up to 30 users per tenant, daily backup, 700–1600 log/s, Scalable | While Label License | In the next sections we explore the different installation types by OFA configuration, providing a typical sizing example for a cloud provider (GCP) along with indicative infrastructure costs. *** ## 2. P-Micro The **P-Micro** sizing solution targets a **testing environment**, enabling the installation of the OneFirewall solution on a **single VM**. ### Requirements and Costs | Requirements | Description | Monthly Cost (USD) | | :-------------------- | :----------------------------------------------- | :------------------- | | 1 VM (Compute Engine) | `n2-standard-8` (Spot Instance) | 39.40 | | 1 SSD (gp3) | 500 GB (persistent volume/standard-rwo) | 98.60 | | Cloud NAT | Internet update, app.onefirewall.com, gitlab.com | 41.50 (100 GB/month) | | Snapshot | N/A | 0 | | **Total** | | **179.50 USD/month** | For **Compute Engine (CE)** or **Google Kubernetes Engine (GKE)**, the system or Kubernetes user must be able to independently configure the environment (`sudoers` privileges or unrestricted RBAC management). *** ## 3. P-0 (ProdSmall) ### Requirements and Costs | Requirements | Description | Monthly Cost (USD) | | :------------------------- | :-------------------------------------------------------- | :------------------- | | 1 VM (Compute Engine) | `n2-standard-8` (Committed Use Discount) | 148.04 | | 1 SSD (gp3) | 30GB node + 1000 GB (persistent volume/standard-rwo) | 197.20 | | Cloud NAT | Internet update, app.onefirewall.com, gitlab.com | 41.50 (100 GB/month) | | External Load Balancer 443 | e.g. `onefirewall.example.it` (or ingress GKE equivalent) | Variable | | Snapshot | 1 per day | — | | **Total** | | **376.74 USD/month** | Compute Engine or GKE users must have privileges to configure the environment (`sudoers` or unrestricted RBAC), and IAM rules for ingress and external load balancer 443. *** ## 4. P-1 (ProdMedium) ### Requirements and Costs | Requirements | Description | Monthly Cost (USD) | | :--------------------------------------------------------------- | :-------------------------------------------------------- | :-------------------- | | 3 VM (Compute Engine) — one per AZ (or GKE Multi-Node, Multi-AZ) | `n2-standard-8` (Committed Use Discount) | 73 (GKE) + 444.12 | | 3 SSD (gp3) | 30GB node + 1000 GB each (persistent volume/standard-rwo) | 591.60 | | Cloud NAT | Internet update, app.onefirewall.com, gitlab.com | 41.50 (100 GB/month) | | External Load Balancer 443 | e.g. `onefirewall.example.it` (or ingress GKE equivalent) | Variable | | Snapshot | 1 per day | — | | **Total** | | **1108.72 USD/month** | Users must be able to configure the environment independently (`sudoers` or unrestricted RBAC), and manage IAM rules for ingress and external load balancer 443. *** ## 5. P-2 (ProdEnterprise) ### Requirements and Costs | Requirements | Description | Monthly Cost (USD) | | :----------------------------------------------------------------- | :-------------------------------------------------------- | :-------------------- | | 3–5 VM (Compute Engine) — one per AZ (or GKE Multi-Node, Multi-AZ) | `n2-standard-8` (Committed Use Discount) | 73 (GKE) + 740.20 | | 3 SSD (gp3) | 30GB node + 1000 GB each (persistent volume/standard-rwo) | 986.00 | | Cloud NAT | Internet update, app.onefirewall.com, gitlab.com | 41.50 (100 GB/month) | | External Load Balancer 443 | e.g. `onefirewall.example.it` (or ingress GKE equivalent) | Variable | | Snapshot | 1 per day | — | | **Total (up to)** | | **1840.70 USD/month** | For Compute Engine or GKE, users must have `sudoers` or unrestricted RBAC access, and appropriate IAM rules for ingress and external Load Balancer 443.
