Disaster Recovery
Disaster Recovery (DR) is a methodology and set of processes for restoring IT infrastructure, applications, and data after a disruptive event such as natural disasters, cyberattacks, or hardware failures. It involves planning, implementing, and testing strategies to ensure business continuity and minimize downtime. Key components include backup systems, recovery procedures, and failover mechanisms to maintain operational resilience.
Developers should learn Disaster Recovery to design and build resilient systems that can withstand failures and quickly recover, which is critical for high-availability applications in industries like finance, healthcare, and e-commerce. It's essential when working with cloud services, distributed systems, or any production environment where downtime leads to significant financial or reputational loss. Understanding DR helps in implementing robust backup strategies, automating recovery processes, and ensuring compliance with regulatory requirements.
