ROI

Sentiment score
3.6
Isovalent enhances operational efficiency with time savings and reduced staffing, offering immediate cost benefits but lacking concrete financial data.
Sentiment score
7.0
NETSCOUT Network & Application Observability enhances uptime, productivity, and savings by reducing troubleshooting time and integrating well with existing products.
I have seen a return on investment, principally in time saved, because I invest considerable time creating and developing the solution using Isovalent.
Dev Ops Engineer at a tech vendor with 10,001+ employees
In reducing overall latency to the numbers I mentioned before, this has increased usability without spending more money, so a return on investment is instantaneous.
SE at Cisco
I think the return on investment question is not the best for me because if the metric includes decreased time of support related to network issues for the deployed applications, then fewer employees are needed from the support team.

Featured Reviews

Clayton Daigle - PeerSpot reviewer

Securing cloud-native AI workloads has improved observability and reduced latency for partners
I think they need to continue developing their load balancing and possibly even a more efficient DNS system. User interfaces are dependent on each customer, whether they're going to use something like Grafana or, in our case at Cisco, we will be using Splunk. The observability parts within Timescape are fine, and I am sure they will improve over time. Governance and security depend on the approach each customer will take to deploying the systems. You can do the minimums or really dive into observability and governance over any of the ecosystems. This is an individual journey, and Isovalent makes it easier. Before Isovalent, we struggled with just simple pod observability with products like Kalisti that sat on the side of the sidecar. Adding all these products added latency, so we tuned the environment as quickly as possible to be as efficient as possible, especially if you're using cloud resources.

Monitoring has improved bandwidth insights and application diagnosis but setup and costs still need work
They need room for improvement about the spare parts. There are shortages in Egypt in their stock. We tried to make RMA for specific parts, and it took a long time. Comparing this to a vendor like Cisco, who provides any component next business day, NETSCOUT nGeniusONE took a long time. This needs more improvement. I believe it is expensive. They need to reduce its budget a little bit. Comparing to other solutions, it is very expensive.
