Excerpt

Scenario Description

Info

NOTE: All hardware in use for supporting the platform is maintained within your enterprise infrastructure on AWS.

  • Installation of 
    D s product
     on an EC2 server in AWS
  • Installation of 
    D s item
    itemdatabases
     on AWS
  • Integration with a supported EMR cluster.
  • Base storage layer and backend datastore of S3

For more information on deployment scenarios, see Supported Deployment Scenarios for AWS.

Product Limitations

For general limitations of 

D s product
, see Product Limitations in the Planning Guide.

Pre-requisites

Please acquire the following assets:

    • License Key: As part of the installation package, you should receive a license key file. See License Key for details.
    • For more information, contact 
      D s support
      .
  • Offline system dependencies: If you are completing the installation without Internet access, you must also acquire the offline versions of the system dependencies. See Install Dependencies without Internet Access.

AWS desktop requirements

  • All desktop users must be able to connect to the EC2 instance through the enterprise infrastructure.

AWS pre-requisites

Depending on which of the following AWS components you are deploying, additional pre-requisites and limitations may apply. Please review these sections as well.

Preparation

Before you install

D s product
on AWS, please verify that you have completed the following:

  1. Read: Please read this entire document before you create the EMR cluster or install the 
    D s platform
    .
  2. VPC: Enable and deploy a working AWS VPC.
    1. In your VPC. you must define a subnet where you plan to deploy the
      D s node
      .
  3. S3: Enable and deploy an AWS S3 bucket to use as the base storage layer for the platform. In the bucket, the platform stores metadata in the following location:

    Code Block
    <S3_bucket_name>/trifacta

    See https://s3.console.aws.amazon.com/s3/home.

  4. IAM Policies: Create IAM policies for access to the S3 bucket. Required permissions are the following: 
    • The system account or individual user accounts must have full permissions for the S3 bucket:

      Code Block
      Delete*, Get*, List*, Put*, Replicate*, Restore*
    • These policies must apply to the bucket and its contents. Example:

      Code Block
      "arn:aws:s3:::my-trifacta-bucket-name"
      "arn:aws:s3:::my-trifacta-bucket-name/*"
    • See https://console.aws.amazon.com/iam/home#/policies
  5. EC2 instance role: Create an EC2 instance role for your S3 bucket policy. See https://console.aws.amazon.com/iam/home#/roles.
  6. EC2 instance: Deploy an AWS EC2 with SELinux where the 
    D s item
    itemsoftware
     can be installed.
    1. The required set of ports must be enabled for listening. See System Ports in the Planning Guide.

    2. This node should be dedicated for 

      D s item
      itemuse
      .

      Info

      NOTE: The EC2 node must meet the system requirements for installing the platform. For more information, see System Requirements in the Planning Guide.

  7. EMR cluster: An existing EMR cluster is required. 
    1. Cluster sizing: Before you begin, you should allocate sufficient resources for sizing the cluster. For guidance, please contact your 

      D s item
      itemrepresentative
      .

    2. See Deploy the Cluster below.
  8. Databases: 
    1. The platform utilizes a set of databases that must be accessed from the 
      D s node
      . Databases are installed as part of the workflow described later.
    2. If installing databases on Amazon RDS, an admin account to RDS is required. For more information, see Install Databases on Amazon RDS.

AWS Information

Before you begin installation, please acquire the following information from AWS:

  • EMR:
    • AWS region for the EMR cluster, if it exists.
    • ID for EMR cluster, if it exists
      • If you are creating an EMR cluster as part of this process, please retain the ID.
      • The EMR cluster must allow access from the 
        D s node
        . This configuration is described later.
  • Subnet: Subnet within your virtual private cloud (VPC) where you want to launch the 
    D s platform
    .
    • This subnet should be in the same VPC as the EMR cluster.
    • Subnet can be private or public.
    • If it is private and it cannot access the Internet, additional configuration is required. See below.
  • S3:
    • Name of the S3 bucket that the platform can use
    • Path to resources on the S3 bucket

  • EC2: 
    • Instance type for the 
      D s node

Internet access

Deploy the Cluster

In your AWS infrastructure, you must deploy a supported version of EMR across a recommended number of nodes to support the expected data volumes of your 

D s item
itemjobs
.
