Effective as a vector store, serverless architecture but there aren't enough security features

The pricing aspect is a concern. The service is way too costly. For the past month, I used only 30 to 40 MB of data, and the cost was $500. AWS could improve pricing. Even being serverless, it incurs charges during idle times. For just holding data, you need to create a list. AWS should add an option to make data idle, so it won't include computing charges. They charge for OCU units based on the time the serverless solution is up, not on indexing or retrieval speed. Once the service starts, it starts getting billed. It would help if there were an option to limit computing. When using it as a database, storing data without frequent fetching would save computing costs.

Helps improve our incident response time, and our mean time to resolve, but visibility is limited

In my previous project, I successfully led the end-to-end deployment of a Splunk migration. The process went smoothly thanks in part to Splunk's professional services team. They conducted a thorough assessment, identified all our potential pain points, and developed a tailored solution and migration plan. This comprehensive approach ensured a seamless transition. Our core deployment team consisted of 5 internal members and two specialists from Splunk. Additionally, the project included a project manager and a product owner. We also benefited from the expertise of two professional service consultants and two representatives from the customer's side. An on-site admin architect further provided valuable technical support. Throughout the deployment process, we leveraged support from various resources whenever necessary. This included assistance with configuration changes, deployments, and other related tasks. We also collaborated effectively with our teammates to ensure a smooth and successful implementation.

Quotes from Members

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

Pros

"The business analytics capabilities are the most important feature it provides."

"Amazon OpenSearch Service provides a managed database solution, so we don't need to manage everything ourselves."

"This service already sorts data like vectors. They have classified the storage pre-defined."

"We retrieve historical data with just a click of a button to move it from cold to hot or warm because it's already stored in the backend storage"

"The customer service is excellent, rated nine out of ten."

"Amazon OpenSearch Service has enhanced our organization's ability to store and search large amounts of data efficiently."

"ITSI includes a feature called a glass table."

"One of the excellent features is the service analyzer, which is truly impressive."

"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."

"The most valuable feature is event correlation, which ensures that only one ticket is generated per issue, eliminating duplicates and reducing noise from multiple alerts."

"The most valuable features are the service analyzer and Glass Tables."

"The search function is the most valuable. It includes regular expressions and wild card searches. We'll write searches using field and case-sensitive services and use all of these search types to write an alert condition. Splunk ITSI has another feature called Glass Table that offers a visual representation."

"We can automate routine tasks. We're able to create alerts, reports, scheduled searches, et cetera. It's helping us to save time."

"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."

Cons

"One improvement I would like to see is support for auto-scaling."

"The pricing aspect is a concern. The service is way too costly. For the past month, I used only 30 to 40 MB of data, and the cost was $500. AWS could improve pricing."

"They can enhance data visualization."

"It would be beneficial to have some level of customization available in the managed service, tailored to the specific use cases of the end users."

"The price is fair yet leans towards the expensive side. I'd rate it five out of ten with respect to capabilities vs. cost."

"One improvement I would like to see is support for auto-scaling."

"After upgrading Splunk ITSI from version 4.11 to 4.13, the analyzer stopped finding values for KPS and services."

"We also faced challenges relating to UI development."

"We have problems doing upgrades and operating alternate new versions."

"They should make it easier to use. Many people are new to it. It is hard and has a steep learning curve."

"Splunk ITSI generates numerous false positives and has the potential for enhancement."

"We're using predictive analytics, and there are three or four algorithms. It would be helpful if this process were more standardized and scalable."

"The user interface visualization could be improved."

"It is pretty okay. I am not sure whether the current release has already moved to the new framework where instead of the glass tables, we can directly use the Dashboard Studio. It would be nice to have that integrated into the same framework."
