Configuring and Launching an Instance
Once you have Configured your network settings on AWS, you are ready to configure and launch the instances that you will later install vertica onto. An Elastic Compute Cloud (EC2) instance without a Vertica AMI is similar to a traditional host. Just like with an on-premises cluster, you must prepare and configure your cluster and network at the hardware level before you can install Vertica.
When you create an EC2 instance on AWS using a Vertica AMI, the instance includes the Vertica software and a standard recommended configuration. The Vertica AMI acts as a template, requiring fewer configuration steps. Vertica recommends that you use the Vertica AMI as is – without modification.
Using the network configurations you created earlier, configure an instance in AWS:
- Select the Vertica AMI from the AWS marketplace.
- Select a supported instance type.
- Specify the number of instances you want to launch. A Vertica cluster uses identically configured instances of the same type. You cannot mix instance types.
- Choose your VPC.
Note: Not all data centers support VPC. If you receive an error message that states "VPC is not currently supported…", choose a different region and zone (for example, choose us-east-1e rather than us-east-1c).
- Assign a Placement Group.
Add Storage:
- Add storage to your instances based on your needs. Consider the following:
- Open Text Corporation recommends that you add a number of drives equal to the number of physical cores in your instance. For example, for a c3.8xlarge, add eight drives. For an r3.4xlarge, add four drives.
- Open Text Corporation does not recommend that you store your information on the root volume.
- For optimal performance with EBS volumes, Amazon recommends that you configure them in a RAID 0 array on each node in your cluster.
- Open Text Corporation recommends that you create your storage when you create your instances. This allows AWS to optimize storage performance.
Configure Security Group:
- Choose between your previously configured or the default Security Group.
- Choose the key value pairs you intend to use with Vertica.
Launch Instances:
- Verify that your instances are running.
