Easily Search and Analyze Data Using AWS OpenSearch Serverless

Overview

In this blog, we are going to know the use case of the OpenSearch Serverless resource launched recently.

To understand OpenSearch Serverless, we will have an introduction on the AWS OpenSearch.

Introduction

Machine-generated data is increasing exponentially. Obtaining insights is crucial for the organization. For that, we require search and analytics tools that are scalable, quick, and flexible.

Before diving in, it’s important to understand how Elastic Search, a third-party tool, operates.

Elasticsearch’s search engine features, which are based on Apache Lucene, make it ideal for storing unstructured data and retrieving it quickly when needed.

Elasticsearch is ideal for various systems: Analytics for business data. Fraud and security detection.

AWS OpenSearch Service

Elastic Search was used to create the AWS Open Search Service, an open-source distributed search and analytics platform.

• It facilitates our ability to carry out interactive log analytics.
• Monitoring applications in real-time, searching websites, and more.
• It includes visualization features supported by an associated Kibana version and an open search dashboard.
• By automating provisioning, software installation and patching, storage tiering, and other processes, removes the operational overhead and lowers costs.
• It is used to swiftly search our unstructured and semi-structured Data to discover the information you need.
• And with built-in machine learning, you can detect anomalies in real-time, Autotune your cluster, and personalize search within your applications, websites, and data lakes.

AWS OpenSearch Serverless Service

As we know AWS OpenSearch service is a fully managed service that automatically installs, configures, and secures petabyte-scaled workloads on dedicated OpenSearch clusters.

• Custer has full control over its cluster configurations.

For variable and uncertain applications, many clients expect to search and analytics workloads to be run even more simply.

Therefore, running petabyte-scale workloads is made simple with the New AWS Open source Serverless option without having to worry about clusters.

Open Search Serverless automatically provisioned and continuously adjusted resources for analytical workloads to maintain performance despite shifting usage patterns and demands.

For Example,

OpenSearch Serverless immediately scales the resources to ingest and store the data when an application monitoring Workload experiences a sudden spike in logging activity during an availability incident.

Similar to this, Open Search Serverless automatically increases the resources for query processing without affecting the performance of data intake when a website search engine experiences an unexpected rise in requests following a news event.

Open Search Capabilities may be easily used by using the new serverless option.

Pay for the resources you utilize.

Amazon OpenSearch Serverless Pricing

• You only pay for the resources used by the workload when using Amazon OpenSearch Serverless.
• OpenSearch Serverless assesses separate fees for computing and storage.
• OpenSearch compute units are used to measure the compute capacity (OCUs)
• The amount of OCUs directly relates to the CPU, RAM, Amazon EBS storage, and I/O resources needed to perform queries or index data.
• One OCU includes 6 GB of RAM, a corresponding vCPU, GP3 storage (which is used to offer quick access to the data that is accessed the most), and data transfer to Amazon Simple Storage Service (S3).
• You’ll see that there is just one entry for compute in OCU-hours, and it has two labels: one for data indexing and the other for search.
• OCUs are billed hourly with per-second granularity on a collection basis.
• Data stored on Amazon S3 will be billed by GB-month.
• Customers will be billed for a minimum of 4 OCUs (2x indexing includes primary and standby, and 2x search that includes one replica for HA) for the first collection in an account.
• All ensuing collections may use those OCUs jointly.
• Based on the compute and data required to serve your collections, more OCUs will be added.
• To manage costs, you can define a maximum OCU count per account.

For now, the AWS OpenSearch serverless is on Specific Regions.

• US East (N. Virginia)
• US East (Ohio)
• US West (Oregon)
• Asia Pacific (Tokyo)
• Europe (Ireland)

Pricing changes with respective Regions.

Conclusion

The Option Serverless in AWS OpenSearch enables the user to easily ingest, secure, search, aggregate, view, and analyze data for several use cases such as log analytics, application search, enterprise search, and more.

Customers will have full control over their cluster configurations. If the Customer wants an easier way to run, search, and analyze workloads for variables and Unpredictable applications.

The new Amazon OpenSearch Serverless option makes it easy to run petabyte-scale workloads

without having to think about clusters.

OpenSearch Serverless automatically provisions and continuously adjusts resources for analytics

workloads to provide consistent performance during changing usage patterns and demands.
