Elasticsearch is a popular open-source search and analytics engine for big data use cases such as log and click stream analysis. Amazon Elasticsearch Service manages the capacity, scaling, patching, and administration of Elasticsearch clusters for you while giving you direct access to the Elasticsearch API.

Key Product Features

UltraWarm

UltraWarm is a warm storage tier that complements the existing Elasticsearch hot storage tier by providing less expensive storage for older and less-frequently accessed data while still providing an interactive experience. UltraWarm stores data in Amazon S3 while using custom, highly-optimized nodes, purpose-built on the AWS Nitro System, to cache, pre-fetch, and query that data. This allows you to:

  • Retain up to 3 PB of data in a single Amazon Elasticsearch Service cluster while reducing cost per GB by nearly 90% compared to existing Elasticsearch storage tiers. 
  • Run fast, interactive analytics on both your recent (weeks) and historical (months or years) log data without needing to spend hours or days restoring it from the archives. 
  • Easily query and visualize across both your recent and historical log data via your Kibana interface, enabling you to quickly identify and troubleshoot performance issues.

When searching and analyzing data, you don’t need to worry about which tier of storage that data is currently in as that is handled automatically. To start using UltraWarm, sign in to the AWS console, create an Amazon Elasticsearch Service cluster, and when selecting your nodes, enable UltraWarm. You can select UltraWarm1.medium.elasticsearch or UltraWarm1.large.elasticsearch instances.

Set-up & Configuration from AWS Management Console or API

With a few clicks, you can create Amazon Elasticsearch domains using the domain creation wizard in the console. Each domain is an Elasticsearch cluster in the cloud with the compute and storage resources you specify. You can also create your domains by a making a single Amazon Elasticsearch Service API call through the AWS Command Line Interface (CLI) or the AWS SDK. While creating a new domain you can specify the number of instances, instance types, and storage options. You can also modify or delete existing domains at any time.

Flexible Storage Options

You can choose between local on-instance storage or Amazon EBS volumes to store your Elasticsearch indices. You can specify the size of the Amazon EBS volume to be allocated to the domain and the volume type - Magnetic, General Purpose, or Provisioned IOPS. You can also modify the storage options after domain creation as needed.

Security and Auditing

Amazon Elasticsearch Service lets you securely connect your applications to your managed Elasticsearch environment, from your VPC or via the public Internet. You can configure network access using VPC security groups or IP-based access policies. You can also restrict access to specified authenticated users using AWS Identity and Access Management (IAM). IAM policies can be set up to provide fine-grained access control to the management API for operations like creating and scaling domains and data plane API for operations like uploading documents and executing queries. In addition, you can monitor and audit your domain with AWS CloudTrail, which records AWS API calls for your account and delivers log files to you. The AWS API call history produced by AWS CloudTrail enables security analysis, resource change tracking, and compliance auditing.

Easy Data Ingestion

Amazon Elasticsearch Service supports integration with Logstash, an open-source data pipeline that helps you process logs and other event data. You can set up your Amazon Elasticsearch domain as the backend store for all logs coming through your Logstash implementation to easily ingest structured and unstructured data from a variety of sources. You can also ingest data into your Amazon Elasticsearch domain using AWS IoT or Amazon CloudWatch Logs.

Support for Kibana

Amazon Elasticsearch Service includes built-in support for Kibana, an open-source analytics and visualization platform that helps you get a better understanding of your data. Kibana is automatically deployed with your Amazon Elasticsearch Service domain.

Direct Access to Elasticsearch API

Amazon Elasticsearch Service gives you direct access to the Elasticsearch APIs to load, query and analyze data, and manage indices.

Scaling Options

You can add or remove instances, and easily modify Amazon EBS volumes to accommodate data growth. You can write a few lines of code that will monitor the state of your domain through Amazon CloudWatch metrics and call the Amazon Elasticsearch Service API to scale your domain up or down based on thresholds you set. The service will execute the scaling without any downtime.

Set-up for High Availability

You can configure your Amazon Elasticsearch domains for high availability by enabling the Zone Awareness option either at domain creation time or by modifying a live domain. When Zone Awareness is enabled, Amazon Elasticsearch Service will distribute the instances supporting the domain across two different availability zones. Then, if you enable replicas in Elasticsearch, the instances are automatically distributed in such a way as to deliver cross-zone replication.

Plug-in Support

Amazon Elasticsearch Service comes prepackaged with several plugins available from the Elasticsearch community including, Kuromoji, ICU, Phonetic Analysis, Smart Chinese Analysis plugin, Stempel Polish Analysis plugin, Ingest Processor Attachment plugin, Ingest User Agent Processor plugin and Mapper Murmur3 Plugin. Plug-ins are automatically deployed and managed for you.

Data Durability

You can build data durability for your Amazon Elasticsearch domain through automated and manual snapshots. You can use snapshots to recover your domain with preloaded data or to create a new domain with preloaded data. Snapshots are stored in Amazon S3, which is a secure, durable, highly-scalable object storage. By default, Amazon Elasticsearch Service will automatically create daily snapshots of each domain. There is no additional charge for the automated daily snapshots. In addition, you can use the Elasticsearch snapshot APIs to create additional manual snapshots. The manual snapshots are stored in Amazon S3 and will incur normal Amazon S3 usage charges.

Monitor Domain Performance

Amazon Elasticsearch Service exposes several performance metrics through Amazon CloudWatch including number of instances, domain health, searchable documents, Amazon EBS metrics (if applicable), CPU, memory and disk utilization for data and master nodes. You can use these metrics to monitor the health of your domain and take any necessary actions such as scaling.

Pay-as-you-go Pricing

With Amazon Elasticsearch Service, you pay only for the compute and storage resources you use. There are no minimum fees or upfront commitments. You don’t need a team of Elasticsearch experts dedicated to provisioning, monitoring, and managing the infrastructure. As a result, your total costs of operating Elasticsearch goes down even at large scale.
