distributed systems

In the realm of computing, especially in environments where multiple processes or instances need to access and modify the same resources concurrently, mutual exclusion (mutex) is crucial to prevent conflicts and preserve data integrity. This article explains how to implement a mutex across distributed systems using the flock command in Linux Bash, particularly when the systems share files over Network File System (NFS). Q&A on Implementing Mutex with flock over NFS Q: What is flock and how is it used in Linux? A: flock is a command-line utility in Linux used to manage locks from shell scripts or command line.

In the vast world of software development, especially when dealing with distributed systems, logging is an invaluable practice. Logging helps in tracking down errors, understanding system behavior, and analyzing performance. Properly implemented logs are pivotal for effective monitoring and troubleshooting. In environments largely driven by Linux systems, Bash scripting becomes a handy tool for managing logging. Here, we explore some of the best practices for logging in distributed systems using Linux Bash. One of the first steps in setting up effective logging is to standardize the format of your logs across all components of your distributed system.

In the realm of network services, few are as vital for performance and functionality as NFS, or Network File System. NFS is a protocol that allows users to access files over a network as if they were physically located on their own system’s hard drive. It has been widely adopted due to its straightforward nature and robust capability. This article delves into NFS, how it integrates with Linux, and how you can use Bash commands to manage and troubleshoot NFS. NFS is a client/server application that allows a user on a client computer to access files over a network in a manner similar to how local storage is accessed. NFS, developed by Sun Microsystems in 1984, is now a standard software component found in UNIX and Linux distributions.
