A highly stable and secure solution that has a straightforward setup

Handles workloads and diverse applications efficiently
We have a lot of VMs on Dell PowerEdge Rack Servers. On a single server, we have probably hosted 14 or 15 VMs. Out of these, 8 to 10 are continuously running, and four of them are backup VMs, so it can handle a good workload. For cybersecurity, it is only accessible on the intranet; it is not accessible through the web. We use it for local development purposes, and it is behind our firewall. Its security is strong. We handle a lot of test data for government and confidential customers. It is safe and strong locally. We have not experienced any security issues. Dell PowerEdge Rack Servers have helped to reduce unplanned production downtime if we need to replace a hard disk, instead of completely shutting a server, there is a hot swap feature. It is quite good in that aspect. Usually, for any activity, there is a downtime of about 30 minutes. It has saved a lot of time. We have tried AI workloads for a development environment for a government customer in Singapore. The servers are hosted in Singapore. It is an ML-based engine with AI. It is a government project where data is processed, and we run it on Dell PowerEdge Rack Servers. The benefit of running AI workloads on PowerEdge Servers is that it is easy to allocate memory. The application we are running is memory intensive. It is pretty easy to scale memory and storage.
