Flexible Deployment

zveloDB Offers Several Deployment Options for Fast, Easy, and Seamless Integration of the URL Database

Local SDK

The zvelo SDK is a modular architecture for local, optimized instances of zvelo’s ActiveWeb URL Cache. It can be installed on a local server or cloud network to provide ultra high-speed performance for URL lookups. Based on device requirements — the SDK enables you to choose between a ‘small’(~1GB) or ‘large’ (~8GB) cache of URLs.

Cloud API

The zveloDB Cloud API deployment enables URL queries and category value responses making it ideal for applications with limited local RAM/HDD resources.

Data Feed

The zveloDB Data Feed is a ‘one-way’ feed of newly classified and updated URLs. The data feed provides daily snapshots and hourly delta updates for partners that have the ability and infrastructure to ingest massive amounts of data directly into their systems.
