Quick Start Reference Deployment Guide

Step 1. Prepare Your AWS Account

  1. If you don't already have an AWS account, create one at https://aws.amazon.com by following the on-screen instructions. Part of the sign-up process involves receiving a phone call and entering a PIN using the phone keypad.

  2. Use the region selector in the navigation bar to choose the AWS Region where you want to deploy the software on AWS. For more information, see Regions and Availability Zones. Regions are dispersed and located in separate geographic areas. Each Region includes at least two Availability Zones that are isolated from one another but connected through low-latency links. Deploying your cloud applications across multiple Availability Zones helps you achieve high availability, even in the face of natural disasters that might impact a single Availability Zone.

    
      Choosing an Amazon EC2 region

    Figure 5: Choosing an AWS Region

    Consider choosing a region closest to your data center or corporate network to reduce network latency between systems running on AWS and the systems and users on your corporate network.

    If you’re planning to use a third Availability Zone for a file share witness instance or a third SQL Server node, choose an AWS Region that includes three or more Availability Zones; see the AWS Global Infrastructure webpage for a list.

  3. Create a key pair in your preferred region. To do this, in the navigation pane of the Amazon EC2 console, choose Key Pairs, Create Key Pair, type a name, and then choose Create.

    
      Creating a Key Pair

    Figure 6: Creating a key pair

    Amazon EC2 uses public-key cryptography to encrypt and decrypt login information. To be able to log in to your instances, you must create a key pair. With Windows instances, the key pair is used to obtain the administrator password via the Amazon EC2 console and then log in using Remote Desktop Protocol (RDP), as explained in the step-by-step instructions in the Amazon EC2 User Guide.

  4. If necessary, request a service limit increase for the Amazon EC2 r4.2xlarge instance type. To do this, in the AWS Support Center, choose Create Case, Service Limit Increase, EC2 instances, and then complete the fields in the limit increase form.

    You might need to request an increase if you already have an existing deployment that uses this instance type, and you think you might exceed the default limit with this reference deployment. It might take a few days for the new service limit to become effective. For more information, see the Amazon EC2 User Guide.
