Implementing Content Delivery Networks (CDNs) for static assets and Memcached/Redis layers to reduce database load. Data Tier Management The book's most famous contribution is a that

"Standard consistent hashing causes uneven load due to virtual node distribution. I will use weighted virtual nodes based on CPU capacity of individual servers. For conflict resolution, I cannot use last-write-wins (LWW) because clock skew in distributed systems leads to data loss. Instead, I’ll implement with client-side reconciliation. Furthermore, for anti-entropy, I’ll use Merkle trees in the background to sync divergent replicas without reading all data. Finally, the write path will utilize a commit log (for durability) before updating the in-memory store." Instead, I’ll implement with client-side reconciliation
