Why Using OSGi Pays Out

Automatic continuous monitoring keeps continuous deployment pipelines flowing smoothly and efficiently. Try Instana APM to automatically monitor containers and microservices!

If you are hesitating about introducing OSGi to your company/department, please consider the following benefits:

1. Access control

OSGi with its class loading mechanism prevents unwanted access to internal packages.

Internal packages can be easily refactored without breaking any API, which reduces development cost.

2. Safe

OSGi components explicitly declare their dependencies on other components.

This prevents failures due to incomplete or incompatible class space, which reduces maintenance cost.

3. Reusable

OSGi components explicitly declare and expose their capabilities.
This makes them easily reusable, which reduces development cost.

4. Flexible

Components of an application can be deployed into one container, or into multiple containers (even onto multiple hosts).
The service layer will automatically wire up the application (using proxies for remote components), which reduces development cost.

5. Hot swap

OSGi components can be installed/updated/uninstalled without stopping the application.
This shortens feature delivery time, while lengthens up-time, which reduces operational cost.

6. Support

OSGi is supported by a strong community as well as large computing companies: Oracle, IBM, Samsung, Siemens, Deutsche Telekom, Redhat, Ericsson, and many more.
Good and responsive support channels reduces development cost.

Automatic real-time observability is critical to getting the full benefit of CI/CD. Hear @DevOpsDon discuss how Franklin American Mortgage Company cut their new application deployment time from 6-12 months to 2 weeks with the help of Instana APM.
