Capacity and Planning

Overview

A Cloudify cluster consists of 3 main services:

1. Cloudify Manager
2. Database
3. Messaging Queue

Cloudify cluster topology assures high availability and should be leveraged for mission-critical deployments. Learn more about the Cloudify cluster.

Cloudify Manager Server

For a highly available setup at least two managers are required, and 3 are recommended.

Recommended resources per manager server:

• The recommended spec. is for average use of 1,000 - 2,000 workflows per hour and was certified with 1M deployments.
• Scaling to higher volume can be achieved via:
  • Additional Cloudify Managers - an almost linear scaling was verified leveraging 3 - 6 managers.
  • Higher hardware spec. - a linear scaling was verified with stronger hardware.
• The equivalent AWS instance is c5.xlarge.
• Customized sizing and tunning may further improve the supported scale. Over 2M deployed nodes and over 5,000 workflows per hour were tested in some scenarios.

Database (PostgreSQL) Server

For a highly available setup, 3 database servers are required.

Recommended resources per database server:

• The recommended spec is for average use of 1,000 - 2,000 workflows per hour and was certified with 1M deployments.
• Scaling to higher volume can be achieved via:
  • Higher hardware spec. - a linear scaling was verified with stronger hardware.
• The equivalent AWS instance is r5.large.

Messaging queue (RabbitMQ) Server

For a highly available setup, 3 messaging queue servers are required.

Recommended resources per messaging queue server

• The recommended spec is for average use of 1,000 - 2,000 workflows per hour and was certified with 1M deployments.
• Scaling to higher volume can be achieved via:
  • Higher hardware spec. - a linear scaling was verified with stronger hardware
• The equivalent AWS instance is c5.large.
