What is Amazon OpenSearch Service?

It is a fully managed search and analytics service that makes it easy to deploy, run, and secure an OpenSearch or Elasticsearch cluster in the AWS Cloud. Designed to handle vast volumes of data, this Amazon service offers unparalleled versatility across two following areas:

Real-time search at scale

How Amazon OpenSearch Service Works

You can securely ingest, search, and analyze large volumes of data in real time. It simplifies the process of managing clusters, automatically handling tasks like provisioning infrastructure, patching software, and backing up data, which allows developers to focus more on deriving insights from their data rather than managing the underlying infrastructure.

AWS OpenSearch Frequently Asked Questions

How does OpenSearch relate to Amazon OpenSearch Service?

Amazon OpenSearch Service is based on the OpenSearch project and provides users with all the benefits of using OpenSearch, along with additional features such as automatic scaling, automated backups, and security features like encryption and access control. Amazon OpenSearch Service is a managed service that allows users to set up and operate OpenSearch clusters at scale. It provides users with a fully managed environment for running and scaling their search and analytics workloads in the cloud.

OpenSearch vs. Elasticsearch: what’s the difference?

In terms of functionality and features, both OpenSearch and Elasticsearch offer similar capabilities for search and analytics. OpenSearch is based on the same core technology as Elasticsearch, but it is developed and maintained separately by the OpenSearch community.

However, as OpenSearch is a newer project, it may have some differences in terms of features and performance compared to Elasticsearch. The main differences between OpenSearch and Elasticsearch is the development and governance model. OpenSearch is developed and governed by a community of developers who follow a more open and transparent process. Elasticsearch, on the other hand, is developed and maintained by Elastic, a company that also provides commercial products and services based on Elasticsearch.

In terms of licensing OpenSearch is under the Apache License 2.0, which is a permissive open-source license that allows for both commercial and non-commercial use. Elasticsearch, on the other hand, is dual-licensed under the Elastic License and the Server Side Public License (SSPL).

What tasks does OpenSearch Service handle for me?

It manages several critical tasks on your behalf, including:

Domain Setup
Provisioning infrastructure capacity and installing OpenSearch or Elasticsearch software in your network environment.

Administrative Tasks
Automating common tasks such as performing backups, monitoring instances, and patching software.

Monitoring and Metrics
Integrating with Amazon CloudWatch to produce metrics that provide information about the state of your domains.

Customization
Offering options to modify domain instance and storage settings, simplifying the task of tailoring your domain to your application's needs.

Can I ingest data into OpenSearch Service from S3, CloudWatch, and Kinesis?

Yes. Amazon OpenSearch Service supports ingestion from all of these sources. You can stream logs and metrics from Amazon CloudWatch, deliver data from Amazon Kinesis Data Streams or Kinesis Data Firehose, and ingest historical datasets directly from Amazon S3. You can also use OpenSearch Ingestion pipelines for real-time transformation and routing before the data reaches your domains.
