Cost Comparison: Migrating Your SaaS Infrastructure to KeepSec’s Cloud vs. AWS, Azure, GCP, and OVHcloud
When managing a SaaS business, infrastructure costs can quickly escalate. Many companies choose to move to cloud service providers to benefit from flexibility and scalability, but these options vary widely in cost. In this article, we’ll compare the expenses for a typical SaaS infrastructure on KeepSec’s cloud, AWS, Azure, Google Cloud Platform (GCP), and OVHcloud, so you can see how each option stacks up.
Typical SaaS Infrastructure
SaaS companies rely on a robust infrastructure to meet the demands of their web applications, databases, CI/CD pipelines, caching, and load balancing. Here’s an overview of the infrastructure requirements and cost estimates for each provider.
Key Components and Requirements
- Web Application Servers: 4 to 6 servers, each with 4 vCPUs, 16 GB RAM, and 100 GB SSD storage, handling both frontend and backend processing.
- Database Servers: 2 to 3 high-performance servers with 4 vCPUs, 16 GB RAM, and 1 TB SSD storage, configured with redundancy for high availability.
- CI/CD Runners: 2 to 4 servers with 2 vCPUs and 8 GB RAM to support continuous integration and deployment.
- Cache and Queue Servers: 1 to 2 cache servers (e.g., Redis) and 1 to 2 queue servers (e.g., RabbitMQ), each requiring about 2 vCPUs and 8 GB RAM.
- Load Balancers: 1 to 2 instances to handle traffic distribution, helping maintain high availability.
- VPN Server: 1 to 2 low-resource servers with 1 to 2 vCPUs and 4 GB RAM for secure access to the infrastructure.
Total Resource Needs:
- vCPUs: 35 to 60 across all instances
- RAM: 132 GB to 224 GB
- Storage: 2.64 TB to 4.08 TB SSD
Cost Comparison Across Providers
Each provider offers different pricing structures. KeepSec’s plans are all-inclusive, with dedicated resources, CPU pinning, and unmetered 1 Gbps bandwidth, making them extremely cost-effective.
Note: Unlike KeepSec, most cloud providers charge for data transfer and bandwidth usage. KeepSec includes unmetered 1 Gbps bandwidth by default, which can make a significant difference in monthly costs, especially for high-traffic applications. We’ll illustrate this impact below.
