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
7.0
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.
I have definitely seen a return on investment with Splunk Observability Cloud, particularly through how fast it has grown and how comfortable other teams are in relying on its outputs for monitoring and observability.
 

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
6.8
Splunk Observability Cloud support is generally responsive but can be slow, with improvement needed, especially in the APAC region.
On a scale of 1 to 10, the customer service and technical support deserve a 10.
They have consistently helped us resolve any issues we've encountered.
They often require multiple questions, with five or six emails to get a response.
 

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
7.6
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.
As we are a growing company transitioning all our applications to the cloud, and with the increasing number of cloud-native applications, Splunk Observability Cloud will help us achieve digital resiliency and reduce our mean time to resolution.
I would rate its scalability a nine out of ten.
 

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
7.7
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.
The out-of-the-box customizable dashboards in Splunk Observability Cloud are very effective in showcasing IT performance to business leaders.
The next release of Splunk Observability Cloud should include a feature that makes it so that when looking at charts and dashboards, and also looking at one environment regardless of the product feature that you're in, APM, infrastructure, RUM, the environment that is chosen in the first location when you sign into Splunk Observability Cloud needs to stay persistent all the way through.
There is room for improvement in the alerting system, which is complicated and has less documentation available.
 

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 is expensive, especially when there are other vendors that offer something similar for much cheaper.
It appears to be expensive compared to competitors.
 

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.
Taiwo Ige - PeerSpot reviewer
Alerting improves incident response across teams and enables faster awareness before customer impact
Splunk Observability Cloud could be improved in terms of integrations with more technical add-ons, such as Zoom. Although they have one with Zoom, it's not available in the cloud, so having that feature would be beneficial. Essentially, Splunk should continue expanding to create easier ways to ingest logs from different products. The out-of-the-box customizable dashboards in Splunk Observability Cloud are very effective in showcasing IT performance to business leaders. However, there are aspects that could be improved, such as linking dashboards to one another. While IT leaders may not drill down, it's crucial to create levels of dashboards for technical users to find root causes, making it effective for stakeholders.
