How would you ensure scalability in multi-site deployments?

• A. Use a centralized single-server architecture.
• B. Use distributed architecture, load balancing, data sharding/partitioning, efficient data replication, central monitoring, and standardized configurations.
• C. Manually configure each site with no central oversight.
• D. Create completely independent data silos with no synchronization.

Answer: (C)

To scale across multiple sites, you want a setup that distributes work and data rather than bottlenecking everything through one point. A distributed architecture with load balancing spreads incoming traffic across many servers, so no single server becomes a choke point. Data sharding or partitioning splits data so different sites or servers handle different portions, improving performance and reducing contention. Efficient data replication keeps copies of data in multiple locations for resilience and faster local access, while still allowing a coherent view across sites. Central monitoring gives visibility and rapid alerting across the entire deployment, making proactive management feasible. Standardized configurations ensure every site is provisioned the same way, simplifying deployments, upgrades, and troubleshooting. In contrast, manually configuring each site with no central oversight leads to drift and maintenance chaos, and completely independent data silos prevent coherent data access and reporting.
