What is Performance Engineering
Performance Engineering is a systematic approach for application development to ensure they meet the customer expectations in terms of performance, scalability, and reliability.
Introduction
Performance engineering is a systematic approach to building applications that meet customer expectations for performance, scalability, and reliability.
Performance testing is a subset of Performance Engineering. The intent of performance testing is to check the application under test from a scalability, reliability, and responsiveness point of view. It is performed to ensure that the application maintains its top-notch performance under high load conditions.
Contrast to performance testing, performance engineering is a discipline to ensure that best practices are applied in the product development process.
Performance Engineering allows seamless collaboration between teams, tools, and processes through continuous feedback loops. Here, every stakeholder is equally responsible for application performance that includes developers, product owners, business analyst along with performance engineers.
Why is it important?
Application performance can directly impact an organization's bottom line. Even brief outages can cause significant financial loss, and root-cause analysis in complex systems can take time. This is why performance and user experience must be managed across the full application lifecycle, not only at launch.
What teams should do?
Define KPIs
Teams need clear key performance indicators (KPIs) to define what application success looks like for the business. Success criteria vary by use case. Some systems prioritize transaction reliability over speed, while others require low-latency responses to meet customer expectations.
Manual Analysis
In today's world when everyone is talking about automation, it's equally important to have clear understanding that unless you process and analyze performance test results it's just the data and not the information which helps development team/ business team to take key decisions.
Performance Driven Development
Everyone on team should start thinking about performance right from the requirement analysis or planning. It's always better to invest more time in building RIGHT design and architecture at the start as cost of fixing a performance issue at later stage can be high. This allows teams to set business specific and measurable performance metrics.
Get the Right Performance Engineering Partner
To help ensure an application meets its business objective, engineering teams should seek performance engineering tools that cover multiple technologies, collect data flexibility, and integrate developer tools. Performance engineering calls for end-to-end integration and collaboration from right-to-left and left-to-right along with real-time insights and analytics.
Setting up effective performance engineering practices requires a team with a proven track record in performance-driven development across different business contexts.
