Availability & Reliability
Auto Scaling
NTT DATA eva® is designed for uninterrupted uptime and enterprise scale, processing thousands of conversations per hour and millions per day, with no degradation of performance.
Data Redundancy
Data is "by default" always replicated in multiple availability zones in the Google Cloud regions where NTT DATA eva® operates (US and EU).
Denial of Service (DoS) Protection
NTT DATA eva® cloud infrastructure is protected and isolated in a dedicated WAF and Virtual Private Cloud (VPC) and all the communications between the different components of the solution are done through the VPC firewall and WAF.
Intrusion Detection System (IDS)
At NTT DATA eva®, IDS is available as a commercial option to our customers, providing an additional layer of protection for their platform.
Infrastructure Redundancy
NTT DATA eva® uses infrastructure redundancy to help ensure network availability and decrease the risk of failure.
Quality Assurance Testing
A dedicated QA team is in charge of ensuring the quality of developments, as well as validating all updates to eva cloud environments.
Service Monitoring
At eva® utilizes tools that measure processing queues to verify the timeliness of processing incoming data while monitoring real-time results. Data lost during processing is detected and automatically creates an alert to the Operations and Engineering teams.
Upon the occurrence of errors within Eva, the change management process is followed with a change ticket initiated, and the error is investigated and resolved.
Status Page
Our uptime and all notifications of performance incidents are made public on the following page. We provide postmortems for every significant incident affecting our performance.
