How can you ensure high availability of Mule applications?

To ensure high availability of Mule applications, deploying applications in multiple regions on CloudHub is a key strategy. This approach reduces the risk of downtime, as it allows the application to remain functional even if one region experiences an outage or maintenance. By distributing the application across different geographical locations, you are enhancing its resilience to regional failures, which provides better reliability and performance for users in various locations.

In contrast, deploying applications as single instances does not provide redundancy, making them susceptible to failure if the server or region goes down. Limiting application usage to specific hours does not inherently improve availability; if the application is needed outside of those hours and is not running, it will result in downtime. Avoiding network traffic monitoring might reduce processing overhead but doesn't contribute to the availability or reliability of the application itself. Therefore, deploying across multiple regions serves as a robust method to ensure that the application remains accessible and operational in varied conditions.
