Team Lead for Core Infrastructure at Raiffeisen bank Serbia
Efficient replication and helpful for improving data processing and management
The technology behind Hitachi ShadowImage has been around for a long time, and while it works correctly, it does have some issues. We have experienced problems with it, even though Hitachi provides good hardware. Technical support could also be improved, as it sometimes takes a few days to resolve issues.

Senior Software Engineer at OmniTier Inc
Improved mobile app development and user experience through optimization and security
The most valuable aspects include the optimization of application performance by optimizing API calls for a smoother user experience and faster load times. Furthermore, I restructured our code base to establish a more efficient development workflow. During my tenure, I integrated various security features for mobile applications, such as JWT tokens for secure authentication and data encryption using AES algorithms. I also focused on secure storage options, secure coding practices, and platform-specific security compliance, like Android's SafeNet and iOS Secure Enclave.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable features are its ability to handle large databases efficiently and the asynchronous replication capability."
"The most valuable feature of Hitachi ShadowImage is high-speed data transfer from one server to another. Other solutions would have problems with transferring 50 TB of data. I also like that Hitachi ShadowImage is easy to use."
"It's super easy to use and integrate with."
"The tool's most valuable feature is the Uplynk platform for streaming purposes."
"The customer support and service responsiveness were excellent."
"The product is easy to use and easy to implement."
"The Rules Engine V4 is the most valuable feature."
 

Cons

"We have experienced problems with it, even though Hitachi provides good hardware."
"API and script configuration in Hitachi ShadowImage is sometimes complicated, so this is an area for improvement. Another area for improvement is that the Hitachi ShadowImage interface isn't as user-friendly."
"The web interface of the Verizon Edgecast portal is very old. It's not user-friendly, slow, and it is missing some valuable features like the ability to make bulk changes."
"We could not create more than 15 custom rules."
"The tool needs to resolve its lack of innovation."
"In the next release, I would like to see more global endpoints for their CDN and a lower price."
 

Pricing and Cost Advice

"I don't have pricing information for Hitachi ShadowImage because my manager handled it."
"The product is cheaper compared to other solutions."
"Be careful about the options because to have all the features can be very expensive."
"When I modeled it out, we are spending somewhere between $600 to $800 a month with Verizon EdgeCast."
