Access Control Lists (ACLs) 

An Access Control List (ACL) is a set of rules that determine which users or systems are granted or denied access to specific resources, like files, directories, or network traffic. An ACL acts as a "guest list" for a system, specifying who is allowed in and what they can do.  

Disaster Recovery (DR) 

Disaster Recovery (DR) in compute and storage helps minimize downtime and data loss by using backups, redundancy, and failover systems to keep things running smoothly.  

Backups create copies of critical data for restoration during failures, while redundancy duplicates data and services across multiple locations to prevent single points of failure. Failover systems automatically switch to backup resources if the primary system fails, ensuring minimal disruption.  

Network File System (NFS) 

Network File System (NFS) is a distributed file system protocol that enables clients to access files and directories on a remote server as if they were local to the client machine.  Using a client-server model, an NFS client sends requests to a server, which processes them and enforces access controls. This enables seamless file sharing and collaboration. 

Network Segmentation 

Network segmentation improves security, performance, and manageability by dividing a network into smaller, isolated segments. This practice helps contain potential breaches, preventing them from affecting the entire network. It also reduces network congestion and optimizes traffic flow between segments. Segmentation simplifies management and troubleshooting, making it easier to monitor and address issues. Additionally, industry regulations often require segmentation to ensure data security and compliance, further reinforcing its importance in modern network architecture. 

Performance Monitoring  

Performance monitoring is the process of tracking and analyzing the performance of technical systems, applications, or projects to identify potential issues, measure progress, and ensure that performance goals are being met. 

Server Message Block (SMB) 

Server Message Block (SMB), also known as Common Internet File System (CIFS), is a network protocol that allows computers to share files, printers, and other resources over a network. Operating at the application layer of the OSI model, SMB facilitates client-server communication for efficient resource sharing.
