What is the focus of resource redundancy in cloud architecture?

1. Increasing access speed to data

2. Preventing data breaches

3. Ensuring system reliability and availability

4. Reducing operational costs

The correct answer is: Ensuring system reliability and availability

Resource redundancy in cloud architecture primarily focuses on ensuring system reliability and availability. This concept involves creating multiple instances of resources, such as virtual machines, databases, or storage systems, to safeguard against hardware failures or service outages. By having backup resources readily available, cloud systems can maintain operational continuity, allowing applications and services to remain accessible even when some components experience issues. This approach is crucial in cloud environments, where high availability is critical for business operations. Many organizations rely on their cloud infrastructure to serve customers around the clock; therefore, implementing redundancy ensures that any failure of one component does not lead to overall system downtime. High availability strategies often involve techniques such as load balancing, failover mechanisms, and geographic distribution of resources, all aimed at enhancing resilience against failures. While other options mention important aspects of cloud architecture, they do not directly relate to the primary goal of resource redundancy, which is to maintain uninterrupted service and reliability. For instance, while increasing access speed to data is essential, it is more about performance optimization rather than redundancy. Similarly, preventing data breaches is a security concern, and reducing operational costs focuses on budget management, neither of which align with the primary intent of redundancy in cloud services.
