Forward-based resource delivery network management techniques

A computer-implemented method for managing a resource delivery network including a plurality of tiers, comprising:

• under control of one or more computer systems configured with executable instructions,
• reading, by a first server associated with a first data store, first write data of a second server in a tier of the resource delivery network, the first write data identifying one or more writes to a second data store associated with the second server;
• obtaining, by the first server, one or more first resources identified in the first write data;
• storing the one or more first resources to the first data store;
• comparing the one or more first resources to one or more second resources of a third server in a preceding tier of the resource delivery network;
• determining that at least one of the second resources is not included among the one or more first resources;
• obtaining, by the first server, the at least one of the second resources;
• storing the at least one of the second resources to the first data store;
• and
• adding the first server to the tier.
