An Event Mechanism for Linux

Telecom applications have extraordinary requirements for low latency and high complexity. An asynchronous event mechanism can be the basis of meeting them.
Conclusion

An event-based mechanism provides a new programming model that offers software developers unique and powerful support for asynchronous execution of processes. Of course, it radically differs from the sequential programming styles we are used to but offers a design framework better structured for software development. It also simplifies the integration and the interoperability of complex software components.

The strength of such a mechanism is its ability to combine synchronous code and asynchronous code in the same application—or even mix these two types of models within the same code routine. With this hybrid approach, it is possible to take advantage of their respective capabilities depending on the situation. This model is especially favorable for the development of secure software and for the long-term maintenance of mission-critical applications.

In a future article, we will show how AEM has been implemented to provide this support in the Linux kernel and how to use it for software development.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
