End-to-end topology stitching and representation is described. An example includes instructions for receiving, at a server, a set of configuration data for an infrastructure stack, the set of configuration data including configuration data for each of a plurality of domains of the infrastructure stack; parsing the received set of configuration data; stitching together an end-to-end topology for the plurality of domains of the infrastructure stack based at least in part on the parsed set of configuration data; and generating a representation of the end-to-end topology of the infrastructure stack.

End-to-end topology stitching and representation

Methods for estimating cost savings in a storage system using an external host system. One method includes accessing over a communication network data from a unit of storage of a data storage system, wherein each of the blocks of data is uncompressed. A plurality of blocks is parsed from the data. A plurality of fingerprints is generated from the blocks using a hash algorithm. A deduplication ratio is estimated for the plurality of blocks stored in the unit of storage using a hyperloglog algorithm and a first plurality of buckets compartmentalizing the plurality of blocks, wherein the first plurality of buckets is defined by precision bits of the plurality of fingerprints. An effective compression ratio is estimated for the plurality of blocks stored in the unit of storage using the hyperloglog algorithm and a second plurality of buckets compartmentalizing the plurality of blocks, wherein the second plurality of buckets is defined by ranges of compression ratios.
