In many domains, transfer of static and batch files is an important part of systems integrations and a large number of applications produce and expect data in the form of files rather than network-based APIs. In this article, we shall see how Zato makes multi-protocol integrations of this kind possible in a way that is secure, scalable and easy to extend in Python.

Enabling rate-limiting in Zato means that access to Zato-based APIs can be throttled per endpoint, user or service - including options to make limits apply to specific IP addresses only - and if limits are exceeded within a selected period of time, the invocation will fail. Let’s check how to use it all.

Dariusz Suchojad
June 23, 2020

Zato startup callable objects are a means through which arbitrary Python functions or classes can be invoked when a server is booting up in order to influence its configuration or setup, even before any service is invoked.

This technique offers customisation possibilities in addition to the standard configuration options set before a server starts - read on to learn details.
