Canary deployments are a reliable software deployment strategy that reduces the risk of introducing a new software version in production by slowly rolling out the change to a small subset of users before making it available to everybody. The canary release gets its name from the "canary in a coal mine" concept, serving as an early warning to detect problems before they affect the majority of users. This strategy is particularly valuable in cloud environments where applications must be continuously integrated and delivered with minimal downtime. In this article, we'll walk through the steps to use Linux Bash scripts to automate the process of canary deployments for cloud applications.

Deploying applications into the cloud environment is an essential skill for modern developers and IT professionals. However, ensuring these applications perform reliably and can be rolled back swiftly in case of a failure is equally crucial. Automation of deployment and rollback processes not only minimizes human errors but also enhances the efficiency and reliability of operations. In this guide, we'll explore how you can leverage Linux Bash to automate rollback strategies for your cloud applications, ensuring your deployments are as resilient as they are robust. Before diving into the automation process, it’s important to understand what a rollback is.

In the world of cloud computing, application logs play a crucial role in monitoring, debugging, and ensuring the smooth operation of services. As applications generate logs incessantly, these logs can grow to huge sizes, leading to issues like insufficient disk space, decreased performance, and difficulties in handling and analyzing data. Log rotation is an essential maintenance task that involves periodically archiving old log files and starting a new one. This article outlines a comprehensive guide on setting up log rotation for cloud-based applications on a Linux system using the logrotate utility. logrotate is a robust command-line utility in Linux specifically designed for managing system log files.
