Proactive failure testing has increased confidence and reliability across complex microservices
There are certain areas where I think Gremlin Reliability Management Platform can improve. I would certainly add features related to AI and GenAI for recommendations. While dependency identification works well seamlessly, deeper dependency intelligence is lacking. When you have deeper dependencies, reliability management can struggle with identifying those deeper dependency intelligences. Having the intelligence to deeply analyze dependencies will be very helpful. Regarding reliability scores, while those scores are good, having more actionable reliability scores is something I would recommend adding to the existing system. Initially, when I started with Gremlin Reliability Management Platform certification programs, I completed two certifications with Gremlin—one professional and another practitioner. While that certification has helped me, an easier onboarding and learning curve for bringing people into this program can be adjusted. That is one current gap I see. If you really look at the cost-benefit visibility, it is not very evident by using Gremlin Reliability Management Platform. If Gremlin Reliability Management Platform could help realize that and bring in visibility regarding the cost versus the benefit, that is the reason I provide a score less than ten. From a standpoint of simulating complex real-world failures, I believe there is still a gap concerning gap identification. Currently, Gremlin Reliability Management Platform mainly focuses on infrastructure-level failures and does not really simulate business logic failures, data corruption scenarios, or potential failures across regions. One of the key elements needing improvement with Gremlin Reliability Management Platform is the limited team workflow integration I see in my organization. Collaboration and limited team workflow integration are areas I would highlight as needing improvement.

Quotes from Members

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

Pros

"Using Gremlin Reliability Management Platform has raised more than fifty percent of the reliability of the infrastructure."
"The Enterprise Reliability Platform has positively impacted my organization as it has significantly increased the efficiency and reliability of our systems."
"Gremlin Reliability Management Platform has positively impacted our organization by making outages less frequent and improving recovery time significantly, resulting in fewer complaints on the customer success side and overall optimization of our DevOps process."
"Gremlin Reliability Management Platform has impacted my organization positively as it helped a lot and reduced our failures, allowing us to find critical pinpoints in our application that had existed for three to ten months and led to too many improvements, reduced downtime, and a smoother experience for our application on AWS."
"More than anything, we fix failures even before they occur, which is basically proactive risk detection and risk mitigation."
"Gremlin Reliability Management Platform is amazing with the reliability score, providing built-in Chaos Engineering experiments that you run on your service to receive a reliability score along with insights on the issues and risks present in your service that you can examine and work on."
"We are seeing a return on investment from using Gremlin Reliability Management Platform because we are getting less production issues by thirty percent, as I mentioned earlier, making it a great investment."
"Since using Gremlin Reliability Management Platform, we were able to reduce the incidents by six percent after conducting our limited experiments, and we were also able to increase the uptime from ninety-eight to ninety-nine, which represents a one percent increase in uptime."
"The Real User Monitor, with its transaction and synthetic transaction monitoring, is the typical classic in APM cases when the customer would like to do transaction monitoring. Micro Focus scores better where the underlying infrastructure management is also covered by Micro Focus tools."
"If you have an old-fashioned infrastructure with data center servers then this is a good solution for you."
"The most valuable feature is application performance monitoring."
"The Micro Focus technical support is quite good."
"Real User Monitor does its job, and that is why we have stayed with it for so many years."
"The reporting feature is good for us."
"Real User Monitor has made it easier to drill down and see how users connect to and use our website."
"Real User Monitoring tools help proactively identify problems before they become critical by monitoring thresholds. There is a threshold and an SOA threshold."
 

Cons

"I think that it will be important to have resources to perform self-directed studies on Gremlin Reliability Management Platform as an improvement."
"I think Gremlin Reliability Management Platform can be improved by integrating with more AWS services or GCP services."
"Gremlin Reliability Management Platform can be improved as the pricing is a bit expensive and the learning curve for beginners is a bit difficult."
"I rate it an eight because we are still using it on a trial and error basis, and the pricing could be optimized for better cost visibility and ROI tracking."
"If you really look at the cost-benefit visibility, it is not very evident by using Gremlin Reliability Management Platform."
"The product needs more R&D to make it easier and more compatible with other software."
"Recently we have been facing some stability issues."
"Some issues with login errors."
"This technology is considered to be older."
"If it is a standalone solution, however, I would not recommend Micro Focus."
"Real User Monitor needs to cover more protocols to provide more in-depth information. It could also be better at monitoring voice-related traffic. There is currently no visibility in that channel."
"Customer support needs to improve by bringing in more people who are knowledgeable about the tool, as there are very few left."
"I have to say that I am very disappointed with this solution. It's very heavy, and it is a nightmare to deploy and maintain."
