Hardware estimation events
Hardware requirement estimation introduction
At the beginning of your project, someone sized the development, testing, and production environments based on the expected concurrent number of users, case type volume, and other factors that impact application performance. You may have been part of the initial application sizing exercise, depending on when you arrived on the project. When you perform formal load testing, you see how well your application performs according to key performance indicators (KPIs).
Note: Throughout the development cycle, you can monitor performance of the Pega application using the Pega Predictive Diagnostic Cloud or Pega Autonomic Event Services. The tool you use depends if you are on-premise, using Pega Cloud, or using another cloud environment.
As you add new users and new functionality to the application, the environment infrastructure can become insufficient for what you are asking the application to handle. For example, your new commercial loan request application shortened the process from two weeks to two days. Because the commercial loan application is successful, the personal loan department wants to start using the application. You expect 10 times as many personal loan requests than commercial loan requests and 700 new personal loan processors to start using the application. The effect is similar to adding water to a glass that is not large enough to hold the amount of water you need it to hold: To hold more water, you need a larger glass.
Consider initiating a new hardware sizing estimate if you are:
- Increasing the number of concurrent users
- Introducing a new Pega application, such as Pega Customer Service or Pega Sales Automation
- Increasing the number of background processes, such as agents or listeners
- Introducing a new case type
- Introducing one or more new integrations to external systems, including robotic automations
Pega offers the Hardware Sizing Estimate service to help you assess hardware needs based on current and planned application usage. Even if you are unsure if the application infrastructure needs modification, you can initiate a request with this service for guidance on how to proceed. The resulting estimate includes recommended settings for application server memory, number of JVMs, and database server disk and memory needed to support your application.
