Unified ai gateway has standardized observability and routing for multiple llm applications
The most valuable features are the unified AI gateway, observability, price calculations, routing controls, and guardrails. The universal API makes it easier to switch between and compare models without rewriting large parts of the application. For the organization, Portkey was providing two endpoints, one for the US and another for Europe, which was easily manageable. Some models were supported for the US, some not, some for the EU, and some for both. Switching between providers is very easy with Portkey. The fallback and retry capabilities are also useful because production LLM applications need resilience when a provider is slow, rate-limited, or temporarily unavailable. Cost and latency tracking are valuable because LLM usage can become difficult to manage across teams, but these can be easily managed through Portkey. Observability is the best feature because at the production grid application, the focus is usually on observability, such as how the end user is using it, what the latency is, how many errors occurred within time frames, which models were used, and how many tokens were consumed. These aspects are easy to manage in Portkey. Portkey has significantly improved the organization by streamlining the AI processes being followed. Portkey improves the workflow for centralizing LLM operations instead of every application team building its own logging, routing, fallback, and cost tracking logic. Portkey provides a shared layer for these capabilities so it can be synced between all teams. It helps reduce engineering efforts when experimenting with different providers and models. It also improves visibility into production behavior because request volumes, latency, cost, errors, and model usage can be seen in one place. For teams building multiple GenAI applications, the biggest improvement is standardization. Portkey makes it easier to enforce common practices across observability, reliability, and governance.

The installation process is the first aspect I dislike about Splunk ITSI (IT Service Intelligence). If you do not configure it correctly, you will encounter issues in the search head. Because we use a distributed environment where each component has its own specific roles, installation is critical and requires careful attention. Splunk ITSI (IT Service Intelligence) is built with many applications. It is a compressed file, and when you extract the Splunk ITSI (IT Service Intelligence) app, you receive approximately 19 apps. Some applications, add-ons, and packages must be installed on specific components. If you do not configure an application correctly, it will not work. Sometimes we encounter issues during installation because of this complexity. I believe the installation process should be more uniform, meaning it could be deployed across all components to avoid post-installation issues. Sometimes after installation, you receive errors, and users cannot access Splunk ITSI (IT Service Intelligence). We have experienced this type of issue due to installation errors. I believe there is currently room for improvement regarding scalability. When we create Glass Tables containing many searches, the Glass Tables sometimes fail due to memory constraints, and we receive error pages. Splunk ITSI (IT Service Intelligence) should have a lightweight version to address these concerns. I would rate current scalability as medium.

Quotes from Members

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

Pros

"Portkey has significantly improved the organization by streamlining the AI processes being followed."
"Portkey definitely provides a solid alternative solution for the agent and large model hosting platforms, and it is very helpful for us to explore the possibilities across the industry rather than staying with a few mainstream options."
"Splunk should be used because it provides a better solution in terms of SIEM as well as reporting."
"The modeling required to setup ITSI has been very helpful in providing us a better understanding and a logical view of our services. The modeling is flexible and can be as granular or high level as our needs dictate."
"The flexibility to develop and consolidate many solutions into one platform is great."
"The most valuable features are the agility, being able to ingest many data sources with no limitation on capacity."
"ITSI's most valuable feature is that it's easy to integrate DLP."
"Instant usability of gathered event metrics is available. We have metrics data from systems, and we can use that to instantly get system status and trends."
"What I like the most is the event correlations. It's a file structure, and ITSI has a correlation layer where you can normalize the events from different sources. Once these events are normalized, you set up rules to aggregate them into different or the same attributes. After the rules are defined, you can automate the process to solve the issue automatically."
"The most valuable feature is the Glass Tables. It gives you a nice, good overview of your KPIs. It's really slick and clean."
 

Cons

"One major problem I see with Portkey is that when I had not yet started any trial, it started to denote that I had exceeded the prompt limit."
"The main area for improvement is onboarding and trial experience."
"While integrating services and KPIs in ITSI is straightforward, I found it challenging to analyze them with the service analyzers; specifically, using the deep dive feature to pinpoint the exact source and time of an issue proved difficult."
"Splunk ITSI lacks out-of-the-box solutions for enterprise users."
"One area where Splunk ITSI (IT Service Intelligence) has room for improvement is the high cost associated with it."
"Splunk ITSI should include ease of integration and more templating."
"Some of our customers occasionally require the development of the connectors when there are no native connectors so that we can develop in Python or for customer slash comments as well. If they could adjust that, it would be ideal."
"We also faced challenges relating to UI development."
"I believe the refresh time should be faster."
"We had issues with support that took a long time to resolve."
