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

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

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

"I would definitely recommend Amazon OpenSearch Service to other professionals due to its fast and reliable search capabilities."

"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"

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

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

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

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

"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."

"The most valuable features are the mapping of the entities, which provides a comprehensive analysis, and the service analyzer for thresholding."

"The solution is easy to scale."

"The KPS used to automate the integration policy is the most valuable feature of Splunk ITSI."

"We save substantial time on monitoring tasks because we don't have to search for what we need. Everything is packed, so you can drill down to the end values by just doing the kit. We don't spend a lot of time on this. Splunk ITSI is easy to use and not time-consuming."

"Customers have noted the solution helps streamline incident management."

"The solution's scalability is fine."

Cons

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

"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."

"They can enhance data visualization."

"We faced documentation challenges during integration after migrating from Elasticsearch to Amazon OpenSearch Service. Better documentation on integration, query handling, and a more user-friendly UI could enhance the product."

"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."

"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."

"We also faced challenges relating to UI development."

"Splunk ITSI lacks out-of-the-box solutions for enterprise users."

"If the product had some prebuilt machine learning features, it would add value to our use cases."

"The UI could be updated. Some elements of the KPI section aren't where you'd expect. It looks like a website from 2010 or maybe older. You can't change some things, like if it doesn't word-wrap well. For example, if you have a long list of KPIs that exceed a character limit, you need to hover over them and wait for the HTML text to pop up to see which KPI it is."

"The license cost is expensive."

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

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

"Splunk ITSI consumes a lot of CPU resources."

Pricing and Cost Advice

Information not available

"It depends on how big an organization is. If we have a lot of resources, the licensing needs to be upgraded. If we have a small environment, the licensing cost is definitely going to be less."

"I know that it is expensive, but I do not think there is another solution that can do similar things for that price."

"Splunk ITSI is expensive."

"Splunk is pretty expensive, but it gives you a decent insight into the data. It is easy to learn, and ITSI has a great interface. You can run those queries and pass the data. I"

"Pricing has some room for improvement."

"Splunk ITSI is a pay-per-use service that is priced fairly based on the amount of data we use."

"Pricing was pretty good, and it is possible to just add on the features we want."

"It is interesting. I am not involved that much lately, but if I recall correctly, you license primarily on the volume of data that you are using in Splunk ITSI, but there is no way Splunk can ever check if that is true, so that is interesting. We are not doing it, but someone can pretend to just use 10%, and it would be super cheap. It is tricky, but it is more tricky for Splunk than for us."
