Data Storage & Reliability encompasses the techniques and architectures used to ensure that data is securely stored, readily available, and remains intact even in the face of hardware failures, software bugs, or network issues. At its core, this field focuses on methods such as redundancy, replication, and fault tolerance to protect critical data. Data can be stored locally on physical devices, in cloud infrastructures, or distributed across multiple nodes in a network. Techniques like RAID (Redundant Array of Independent Disks) help protect against individual disk failures, while distributed file systems and databases often employ replication strategies to copy data across multiple servers, ensuring high availability.
Erasure coding (EC) is a data protection technique used in distributed storage systems to improve fault tolerance while minimizing storage… Read More
