Lightstreamer for mission-critical reliability

The primary goal of adesso’s websites is to present financial instrument information for compliance and regulatory purposes. Financial companies must display this information to their customers due to legal requirements. Additionally, stock market clients seek websites with the best features and most relevant complementary information. Since the late 2000s, adesso has used Lightstreamer to push updated prices online. This technology is mission-critical yet also enhances website functionality. Some small companies initially use simple websites with delayed prices or manual updates, later upgrading to push technology to provide real-time updates without requiring page refreshes.

Flexible technology

adesso leverages Lightstreamer to stream live data through the web, updating visible data for customers in real-time for prices, charts, and news. Lightstreamer integrates seamlessly with adesso’s backend technologies and provides SDKs for several server-side frameworks, enabling modern frontend frameworks to receive streaming data. The Lightstreamer JavaScript client library works effortlessly with various client-side technologies, including native mobile apps.

What’s next

adesso plans to continue using Lightstreamer as their streaming technology of choice for upcoming projects, ensuring their clients benefit from the best real-time data solutions available.
