Introducing self-managed knowledge sources for Amazon OpenSearch Ingestion

Enterprise clients more and more undertake Amazon OpenSearch Ingestion (OSI) to convey knowledge into Amazon OpenSearch Service for numerous use circumstances. These embrace petabyte-scale log analytics, real-time streaming, safety analytics, and looking semi-structured key-value or doc knowledge. OSI makes it easy, with easy integrations, to ingest knowledge from many AWS companies, together with Amazon DynamoDB, Amazon Easy Storage Service (Amazon S3), Amazon Managed Streaming for Apache Kafka (Amazon MSK), and Amazon DocumentDB (with MongoDB compatibility).

At present we’re asserting help for ingesting knowledge from self-managed OpenSearch/Elasticsearch and Apache Kafka clusters. These sources can both be on Amazon Elastic Compute Cloud (Amazon EC2) or on-premises environments.

On this publish, we define the steps to get began with these sources.

Resolution overview

OSI helps the AWS Cloud Improvement Equipment (AWS CDK), AWS CloudFormation, the AWS Command Line Interface (AWS CLI), Terraform, AWS APIs, and the AWS Administration Console to deploy pipelines. On this publish, we use the console to display the best way to create a self-managed Kafka pipeline.

Stipulations

To verify OSI can join and browse knowledge efficiently, the next circumstances must be met:

• Community connectivity to knowledge sources – OSI is usually deployed in a public community, such because the web, or in a digital non-public cloud (VPC). OSI deployed in a buyer VPC is ready to entry knowledge sources in the identical or totally different VPC and on the web with an connected web gateway. In case your knowledge sources are in one other VPC, frequent strategies for community connectivity embrace direct VPC peering, utilizing a transit gateway, or utilizing buyer managed VPC endpoints powered by AWS PrivateLink. In case your knowledge sources are in your company knowledge middle or different on-premises atmosphere, frequent strategies for community connectivity embrace AWS Direct Join and utilizing a community hub like a transit gateway. The next diagram reveals a pattern configuration of OSI operating in a VPC and utilizing Amazon OpenSearch Service as a sink. OSI runs in a service VPC and creates an Elastic Community interface (ENI) within the buyer VPC. For self-managed knowledge supply these ENIs are used for studying knowledge from on-premises atmosphere. OSI creates an VPC endpoint within the service VPC to ship knowledge to the sink.
  
• Title decision for knowledge sources – OSI makes use of an Amazon Route 53 resolver. This resolver routinely solutions queries to names native to a VPC, public domains on the web, and data hosted in non-public hosted zones. In case you’re are utilizing a non-public hosted zone, be sure you have a DHCP choice set enabled, connected to the VPC utilizing AmazonProvidedDNS as area identify server. For extra data, see Work with DHCP choice units. Moreover, you should utilize resolver inbound and outbound endpoints for those who want a fancy decision schemes with circumstances which are past a easy non-public hosted zone.
• Certificates verification for knowledge supply names – OSI helps solely SASL_SSL for transport for Apache Kafka supply. Inside SASL, Amazon OpenSearch Service helps most authentication mechanisms like PLAIN, SCRAM, IAM, GSAPI and others. When utilizing SASL_SSL, be sure you have entry to certificates wanted for OSI to authenticate. For self-managed OpenSearch knowledge sources, make certain verifiable certificates are put in on the clusters. Amazon OpenSearch Service doesn’t help insecure communication between OSI and OpenSearch. Certificates verification can’t be turned off. Specifically, the “insecure” configuration choice shouldn’t be supported.
• Entry to AWS Secrets and techniques Supervisor – OSI makes use of AWS Secrets and techniques Supervisor to retrieve credentials and certificates wanted to speak with self-managed knowledge sources. For extra data, see Create and handle secrets and techniques with AWS Secrets and techniques Supervisor.
• IAM function for pipelines – You want an AWS Id and Entry Administration (IAM) pipeline function to jot down to knowledge sinks. For extra data, see Id and Entry Administration for Amazon OpenSearch Ingestion.

Create a pipeline with self-managed Kafka as a supply

After you full the stipulations, you’re able to create a pipeline on your knowledge supply. Full the next steps:

1. On the OpenSearch Service console, select Pipelines underneath Ingestion within the navigation pane.
   
2. Select Create pipeline.
   
3. Select Streaming underneath Use case within the navigation pane.
4. Choose Self managed Apache Kafka underneath Ingestion pipeline blueprints and select Choose blueprint.
   

This can populate a pattern configuration for this pipeline.

5. Present a reputation for this pipeline and select the suitable pipeline capability.
6. Underneath Pipeline configuration, present your pipeline configuration in YAML format. The next code snippet reveals pattern configuration in YAML for SASL_SSL authentication:

   model: '2'
   kafka-pipeline:
     supply:
       kafka:
         acknowledgments: true
         bootstrap_servers:
           - 'node-0.instance.com:9092'
         encryption:
           sort: "ssl"
           certificates: '${{aws_secrets:kafka-cert}}'
           
         authentication:
           sasl:
             plain:
               username: '${{aws_secrets:secrets and techniques:username}}'
               password: '${{aws_secrets:secrets and techniques:password}}'
         matters:
           - identify: on-prem-topic
             group_id: osi-group-1
     processor:
       - grok:
           match:
             message:
               - '%{COMMONAPACHELOG}'
       - date:
           vacation spot: '@timestamp'
           from_time_received: true
     sink:
       - opensearch:
           hosts: ["https://search-domain-12345567890.us-east-1.es.amazonaws.com"]
           aws:
             area: us-east-1
             sts_role_arn: 'arn:aws:iam::123456789012:function/pipeline-role'
           index: "on-prem-kakfa-index"
   extension:
     aws:
       secrets and techniques:
         kafka-cert:
           secret_id: kafka-cert
           area: us-east-1
           sts_role_arn: 'arn:aws:iam::123456789012:function/pipeline-role'
         secrets and techniques:
           secret_id: secrets and techniques
           area: us-east-1
           sts_role_arn: 'arn:aws:iam::123456789012:function/pipeline-role'

7. Select Validate pipeline and ensure there aren’t any errors.
8. Underneath Community configuration, select Public entry or VPC entry. (For this publish, we select VPC entry).
9. In case you selected VPC entry, specify your VPC, subnets, and an acceptable safety group so OSI can attain the outgoing ports for the information supply.
10. Underneath VPC attachment choices, choose Connect to VPC and select an acceptable CIDR vary.
    

OSI assets are created in a service VPC managed by AWS that’s separate from the VPC you selected within the final step. This choice permits you to configure what CIDR ranges OSI ought to use inside this service VPC. The selection exists so you may make certain there is no such thing as a deal with collision between CIDR ranges in your VPC that’s connected to your on-premises community and this service VPC. Many pipelines in your account can share identical CIDR ranges for this service VPC.

11. Specify any optionally available tags and log publishing choices, then select Subsequent.
12. Evaluation the configuration and select Create pipeline.

You possibly can monitor the pipeline creation and any log messages within the Amazon CloudWatch Logs log group you specified. Your pipeline ought to now be efficiently created. For extra details about the best way to provision capability for the efficiency of this pipeline, see the part Really helpful Compute Models (OCUs) for the MSK pipeline in Introducing Amazon MSK as a supply for Amazon OpenSearch Ingestion.

Create a pipeline with self-managed OpenSearch as a supply

The steps for making a pipeline for self-managed OpenSearch are much like the steps for creating one for Kafka. Through the blueprint choice, select Information Migration underneath Use case and choose Self managed OpenSearch/Elasticsearch. OpenSearch Ingestion can supply knowledge from all variations of OpenSearch and Elasticsearch from model 7.0  to  model 7.10.

The next blueprint reveals a pattern configuration YAML for this knowledge supply:

model: "2"
opensearch-migration-pipeline:
  supply:
    opensearch:
      acknowledgments: true
      hosts: [ "https://node-0.example.com:9200" ]
      username: "${{aws_secrets:secret:username}}"
      password: "${{aws_secrets:secret:password}}"
      indices:
        embrace:
        - index_name_regex: "opensearch_dashboards_sample_data*"
        exclude:
          - index_name_regex: '..*'
  sink:
    - opensearch:
        hosts: [ "https://search-domain-12345567890.us-east-1.es.amazonaws.com" ]
        aws:
          sts_role_arn: "arn:aws:iam::123456789012:function/pipeline-role"
          area: "us-east-1"
        index: "on-prem-os"
extension:
  aws:
    secrets and techniques:
      secret:
        secret_id: "self-managed-os-credentials"
        area: "us-east-1"
        sts_role_arn: "arn:aws:iam::123456789012:function/pipeline-role"
        refresh_interval: PT1H

Issues for self-managed OpenSearch knowledge supply

Certificates put in on the OpenSearch cluster must be verifiable for OSI to hook up with this knowledge supply earlier than studying knowledge. Insecure connections are at the moment not supported.

After you’re linked, make certain the cluster has enough learn bandwidth to permit for OSI to learn knowledge. Use the Min and Max OCU setting to restrict OSI learn bandwidth consumption. Your learn bandwidth will differ relying upon knowledge quantity, variety of indexes, and provisioned OCU capability. Begin small and enhance the variety of OCUs to stability between obtainable bandwidth and acceptable migration time.

This supply is often meant for one-time migration of knowledge and never as steady ingestion to maintain knowledge in sync between knowledge sources and sinks.

OpenSearch Service domains help distant reindexing, however that consumes assets in your domains. Utilizing OSI will transfer this compute out of the area, and OSI can obtain considerably greater bandwidth than distant reindexing, thereby leading to sooner migration occasions.

OSI doesn’t help deferred replay or site visitors recording right now; check with Migration Assistant for Amazon OpenSearch Service in case your migration wants these capabilities.

Conclusion

On this publish, we launched self-managed sources for OpenSearch Ingestion that allow you to ingest knowledge from company knowledge facilities or different on-premises environments. OSI additionally helps numerous different knowledge sources and integrations. Check with Working with Amazon OpenSearch Ingestion pipeline integrations to study these different knowledge sources.
