OpenSearch is it worth it, compared to Elastic
Use Cases and Deployment Scope
We needed a solution to how can we give fast responses to our APIs as we needed super fast response times on our websites even if an API is called from the public website we need to have millisecond response times we use db as our long term storage which takes too much times and we used Elastic search previously but after it was hidden behind a paywall we found OpenSearch and loved it cause first it was open source and second we already use AWS as our exclusive cloud provider so after AWS integrated it in their ecosystem it was a no-brainer.
Pros
- Gives us millisecond response times
- Mainly open-source
- Integration Seamlessly with AWS
- Has a very big community so problems are fixes sooner then later
Cons
- Needs more descriptive documentation
- The UI feels a bit old
- Some functionality still doesn't work correctly
Return on Investment
- Well we had 200 ms response times which decreased to 100ms while using OpenSearch
- Easy to use security plugins we dont need external IAM
- Super Easy Integration with many AWS Services such as kinsesi data stream and dynamoDB
