Building resilient, scalable, and secure systems is a top priority for Software Architects and IT Operations Managers. They need to ensure that systems can handle high loads and that sensitive test data is handled securely, all without risking the integrity of live production environments.

Hoverfly Cloud provides the tools to achieve this with confidence. For performance evaluation and load testing, you can simulate high-traffic scenarios to evaluate how your application performs under various conditions, such as slow API responses or unexpected failures. The platform’s simplicity means it can scale to support thousands of transactions per second, making it ideal for large-scale performance testing without the costs and risks of stressing live APIs. This allows IT Operations Managers to predict system behaviour under stress and implement mitigation strategies in advance, leading to fewer outages and happier end-users. The easy-to-use interface also allows you to test under different conditions with various API simulation modes.

Testing for resilience: A pre-production strategy

A software architect is designing a new system that will interact with a third-party payment gateway. They need to ensure the system is resilient to a wide range of API responses, including timeouts, errors, and unexpected data formats. Using Hoverfly Cloud, they can model these various API interactions in a safe, simulated environment. This allows them to identify and fix potential integration issues and failure points early in the development cycle, long before the system ever goes live.

Hoverfly Cloud is also a must for API Providers and Integration Teams. It allows you to safely test integrations with external APIs and to create secure sandbox environments for third-party developers to experiment with your APIs before production use. This provides faster feedback cycles and eliminates concerns of customers or consumers ‘breaking’ live systems.

The platform is also essential for Compliance and Security Testing. You can test how applications handle sensitive data and security vulnerabilities by simulating APIs that return specific data, such as GDPR-related information or token expiry scenarios in OAuth workflows. This proactive approach helps reduce the risk of non-compliance and exposure to security gaps.

By helping system architects model how APIs interact within complex environments and IT teams predict how systems will behave under stress, Hoverfly Cloud helps reduce risks in production environments to build better, more reliable systems.
