Room For Improvement

Users suggest improvements in pricing, upgrades, interface, security, support, integration, backup, and performance visibility for Google Kubernetes Engine.
Splunk Observability Cloud needs enhanced integration, scalability, cost-efficiency, UI, third-party support, and better documentation and customer support.
When looking at the web interface, it feels kind of slow due to the many features involved.
Product Manager at a tech vendor with 11-50 employees
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.
Director at Taotesting
The out-of-the-box customizable dashboards in Splunk Observability Cloud are very effective in showcasing IT performance to business leaders.
IT Operations Engineer at ABC Supply Co. Inc.
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.
Systems Monitoring Engineer II at a government with 10,001+ employees
There is room for improvement in the alerting system, which is complicated and has less documentation available.
Head of DevOps at a tech services company with 1-10 employees
 

Setup Cost

Google Kubernetes Engine offers usage-based pricing with flexibility, but costs may rise with robust configurations and small deployments.
Splunk Observability Cloud is seen as expensive but offers flexible, transparent pricing with potential negotiation for cost-efficiency.
Instead, we only pay for the hardware we use, which results in cost-cutting.
Cloud Associate DevOps at Publicis Sapient
Google is considered cheaper compared to AWS, making it suitable for smaller to medium companies concerning cost.
Product Manager at a tech vendor with 11-50 employees
The on-demand nodes are quite expensive.
Director at Taotesting
Splunk is a bit expensive since it charges based on the indexing rate of data.
Senior Manager at a financial services firm with 10,001+ employees
It is expensive, especially when there are other vendors that offer something similar for much cheaper.
Solutions Architect at Ikusi
It appears to be expensive compared to competitors.
Head of DevOps at a tech services company with 1-10 employees
 

Valuable Features

Google Kubernetes Engine excels with auto-scaling, easy deployment, integration, security, and reduced complexity for seamless application management.
Splunk Observability Cloud offers seamless integration, real-time monitoring, and customization for enhanced visibility, threat detection, and performance optimization.
The most valuable aspect of Google Kubernetes Engine (GKE) is its managed nature, which significantly reduces the burden on our platform team.

Featured Reviews

Parthasarathy T - PeerSpot reviewer
Cloud Associate DevOps at Publicis Sapient
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
IT Operations Engineer at ABC Supply Co. Inc.
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.
