Why Developers Choose HCL Zen Edge Data Management?


Edge applications and devices increasingly rely on AI to improve automation and decisions – human and machine – in stand-alone, peer-to-peer, local network, cloud and hybrid environments. The underlying edge data management must leverage a variety of hardware architectures, operating environments, networks, communications interfaces, and programming and scripting languages for applications that use these resources. Zen Edge Data Management delivers against these broad and demanding requirements.

Friends don’t let friends use flat files


ETL, data security, portability, indexing, time-stamping, and other features built-in to modern edge data management solutions no longer require a complex database that doesn’t fit your edge use case. With Zen you get the simplicity of file system APIs with the robust functionality of a real-time database.

Eight Indicators you need to modernize your Edge Data Management

HCL CLARA AI virtual assistant

Eight Indicators you need to modernize your Edge Data Management


  • Do you need to analyze and make real-time decisions at the point of action?
  • Are you able to manage large sets of local and shared persistent data at the edge?
  • Do you need to run on multiple OSes from Android/iOS to Windows/Linux?
  • Do you use multiple programming and scripting languages to develop your edge applications?
  • Do you support varied types of data: JSON, Blob, traditional structured, etc.?
  • Are you struggling to support standalone, peer-to-peer, client-server, Internet/Intranet architectures?
  • Do you operate as stand-alone when disconnected?
  • Can you handle high-speed, multi-channel data collection and local machine learning inference?
If you’re struggling with any of these questions, you’re probably struggling with your Edge Data Management and need to modernize.
