eViewer 5: What you need to know
Launched in 2019, eViewer 5 was the latest iteration of the HTML5 server-based document viewer. As with all server-based document viewers, the rendering and image processes (i.e. redactions, page rotation, delete page), are managed by the server. These processes can generate a considerable amount of CPU utilization and network traffic, especially as the number of users increases.
The improvements provided in eViewer 5 alleviated many of the pain points organizations faced with CPU load caused by a server-based viewer. By incorporating the latest technology, including Node.JS, eViewer 5, can provide better load balancing for servers where eViewer is deployed. It also has improved image compression technology to reduce network traffic between the server and workstations.
eViewer 7: What you need to know
eViewer 7, released in 2021, is a complete redesign of the HTML5 document viewer. eViewer 7 is a hybrid HTML5 document viewer with rendering and image operations occurring on either the server or the workstation. The server app for eViewer 7 determines if the rendering or image operation needs to occur on the server, and if not, it will be passed to the workstation. This reduces the server load allowing for fewer dedicated servers and reduced network traffic between the server and workstation.
eViewer 7 offers the same features as eViewer 5, such as collaboration annotations, redaction, text copy, and many more. Additionally, users will experience faster rendering and page manipulation operations of documents with eViewer 7 since they occur on their device and not the server.
