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

"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."

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

"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."

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

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

"Our mean time to detect is down to five minutes."

"Having a structure on how to resolve incidents is the most valuable aspect."

"The glass tables are very helpful."

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

"Alerts and episodes are valuable to me."

"The solution has been stable."

"I particularly like the preview feature because it provides a prompt experience for impact analysis."

"ITSI includes a feature called a glass table."

Cons

"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 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."

"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."

"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."

"ITSI currently lacks the capability for automated response, mitigation, and remediation."

"Currently, Glass tables in ITSI only display metrics related to KPIs."

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

"One thing ITSI could improve on is the maintenance windows. I have a huge case where I had to implement something related to the maintenance window. If you try to look up the issues in ITSI, you have to check the incidents individually, and putting hundreds of hosts in maintenance can be a hindrance."

"We're getting alerts with delays of maybe five minutes, however, we'd like to see real-time alerting in the future."

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

"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 experience occasional delays in receiving solutions from Splunk technical support. Splunk's support for P3 cases seems inadequate, as they frequently switch support personnel. For instance, in a single P3 case, we had three different technical support representatives assigned. We were ultimately forced to escalate the issue to our account manager to get it resolved. In essence, we never receive complete support from a single point of contact; instead, the support team keeps changing, necessitating us to explain the problem from scratch each time."
