Enterprise vs. Lite Plan

There are 3 main differences between the Lite and Enterprise plans.

1. Requests Per Month

Requests Per Month are a crucial aspect of the Edge Stack API Gateway pricing structure, catering to different usage scales and business needs.

The Lite plan is tailored for smaller services or early-stage products that experience less than 10,000 requests per month. The Edge Stack API Gateway free tier is an ideal starting point for businesses in their scaling phase or those developing new products. The Lite plan provides a comprehensive API Gateway foundation without overwhelming smaller operations with unnecessary capacity or costs for more messages sent and received. It allows businesses to grow their services organically, ensuring their infrastructure costs align with their current usage and demand.

Despite being designed for lower traffic volumes, the Lite plan still offers a full suite of features necessary for effective API management, making it a robust option for businesses at the beginning of their growth curve.

The Enterprise Plan is suited for larger businesses or services experiencing more than 10,000 requests per month. The pricing for the Enterprise plan is customized based on the specific needs and scale of the business. This approach allows for flexibility and ensures that companies only pay for the required capacity and features.

An essential advantage of the Enterprise plan is the potential for significant cost savings as traffic increases. This plan is designed to scale cost-effectively, offering businesses a reduced cost per request as their traffic grows to millions of REST API calls or millions of HTTP API calls. This aspect is particularly beneficial for rapidly expanding businesses or those with high-traffic applications, as it provides a scalable solution that aligns with the API calls you receive and your evolving requirements.

2. Air-Gapped Clusters

Second is the availability of air-gapped clusters. This functionality enables deployment in fully isolated environments, cut off from external networks, which is critical for maintaining data security and integrity in susceptible environments or subject to strict regulatory standards.

This type of setup is particularly crucial in sectors where data security and integrity are non-negotiable, such as government defense systems, financial institutions, and healthcare organizations handling sensitive information.

The benefits of using air-gapped clusters in such environments include:

Enhanced security.

By physically isolating the network, the risk of external cyber-attacks or unauthorized access is significantly reduced. This setup creates a formidable barrier against malware, ransomware, an

Data integrity

Maintaining data integrity is a security concern and compliance requirement in highly regulated industries. Air-gapped clusters ensure data is not tampered with or altered by external sources, maintaining its accuracy and reliability.
