Executive SummaryUpdated on Jun 19, 2025

Review summaries and opinions

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

ROI

Sentiment score
6.1
Google Kubernetes Engine delivers positive ROI by reducing costs and improving efficiency, despite being costly for some services.
Sentiment score
7.4
Organizations saw improved visibility, productivity, and efficiency, with reduced downtime and costs using Splunk Observability Cloud, enhancing KPIs.
By migrating from AWS to Google Cloud Platform, we have saved a lot of time and money.
Using Splunk has saved my organization about 30% of our budget compared to using multiple different monitoring products.
Anyone working in front-end management should recognize the market price to see the true value of end-user monitoring.
 

Customer Service

Sentiment score
3.7
Google Kubernetes Engine support varies; some users rely on forums, while others suggest improvements in response time and professionalism.
Sentiment score
7.1
Splunk Observability Cloud support is generally responsive but can be slow, with improvement needed, especially in the APAC region.
They often require multiple questions, with five or six emails to get a response.
Support from Splunk is not very helpful because Splunk doesn't have a dedicated APM; they only have one APM engineer in Korea.
They did respond to us, but they did not explicitly inform us about the feature's absence.
 

Scalability Issues

Sentiment score
6.0
Google Kubernetes Engine is praised for its scalability, efficient for microservices, with dynamic auto-scaling adjusting to organizational needs.
Sentiment score
7.8
Splunk Observability Cloud is scalable and flexible but can be costly, with challenges in data ingestion and implementation.
The autoscaling capabilities of Google Kubernetes Engine have significantly impacted our operations.
We've used the solution across more than 250 people, including engineers.
I would rate its scalability a nine out of ten.
The issue is mainly about pricing because if they want to monitor more, it costs money.
 

Stability Issues

Sentiment score
7.5
Google Kubernetes Engine is highly stable, effectively managing demands with regular updates and scalable architecture for reliable operations.
Sentiment score
8.0
Splunk Observability Cloud is highly stable, rated 8-10/10 for reliability, with minor issues usually from user configurations.
If I have 100 replicas of containers and the traffic suddenly pushes to 1,000 within a fraction of a second, the selected machine type must be fast.
I would rate its stability a nine out of ten.
We rarely have problems accessing the dashboard or the page.
Unlike NetScout or regular agents for APM, RUM has many problems during the POC phase because customer environments vary widely.
 

Room For Improvement

Google Kubernetes Engine needs enhancements in security, user interface, scalability, pricing, and third-party integration for optimal performance.
Splunk Observability Cloud requires improved integration, scalability, cost-effectiveness, ease of use, monitoring features, customization, and enhanced customer support.
When looking at the web interface, it feels kind of slow due to the many features involved.
Log observability could be made easier so someone from high school can use it without having technological expertise.
It would be helpful if I could easily find log information in a particular namespace without needing to write certain labels.
There is room for improvement in the alerting system, which is complicated and has less documentation available.
Improvements in dashboard configuration, customization, and artificial intelligence functionalities are desired.
Customers sometimes need to create specific dashboards, particularly for applicative metrics such as Java and process terms.
 

Setup Cost

Google Kubernetes Engine uses pay-as-you-go pricing, competitive with AWS, considering machine specs, compute resources, and optional GPUs.
Splunk Observability Cloud offers advanced features but can become costly as data volume and infrastructure needs grow.
Instead, we only pay for the hardware we use, which results in cost-cutting.
Google is considered cheaper compared to AWS, making it suitable for smaller to medium companies concerning cost.
The on-demand nodes are quite expensive.
Splunk is a bit expensive since it charges based on the indexing rate of data.
It appears to be expensive compared to competitors.
Splunk is a little expensive, however, it is in line with the current market pricing.
 

Valuable Features

Google Kubernetes Engine offers seamless autoscaling, multi-cloud support, robust security, and easy cluster management for enhanced performance and reliability.
Splunk Observability Cloud offers seamless data integration, real-time insights, and efficient monitoring, enhancing performance visibility across diverse environments.
The most valuable aspect of Google Kubernetes Engine (GKE) is its managed nature, which significantly reduces the burden on our platform team.
GKE is easier to understand and use than Elastic Kubernetes Service.
What I find most valuable is the ability to focus solely on my product without worrying about the Kubernetes infrastructure itself.
Splunk provides advanced notifications of roadblocks in the application, which helps us to improve and avoid impacts during high-volume days.
For troubleshooting, we can detect problems in seconds, which is particularly helpful for digital teams.
It offers unified visibility for logs, metrics, and traces.

Featured Reviews

Parthasarathy T - PeerSpot reviewer
Managed solutions enable efficient handling of web applications and migration projects
Google Kubernetes Engine can be improved by enabling the in-place upgrade of the machine type of an existing node pool since I currently need to destroy and recreate it. There is no feature present where I can upgrade directly, and having more than 1,000 to 2,000 workloads in one node pool makes changing the node pool name difficult for all those workloads. I choose eight out of ten mainly because of the node pool upgrade challenge I mentioned, but also because of the existence of Anthos service mesh, which is the ingress controller available only for the enterprise Kubernetes Engine. It would be beneficial if it could be offered in the normal Kubernetes Engine with any limitations.
Lakshmi Padaga - PeerSpot reviewer
Collaborates performance metrics with log data to pinpoint the exact cause of issues and offers error detection
Splunk APM is a robust tool with many capabilities. There are always areas for potential improvement to enhance its functionality and user experience. For Splunk APM, there could be simplified navigation, like streamlining the user interface to make navigation more intuitive for our users, especially those new to APM, which can enhance usability. We can provide more customization options for dashboards and visualizations to help users tailor the platform to their specific needs. There could be more integration capabilities with a wider range of third-party tools and platforms would also be beneficial. By focusing on these areas, Splunk APM can enhance its value proposition, improve user satisfaction, and better meet the evolving needs of organizations monitoring their application performance.
