Amazon cloud services checklist

SharePlex has been successfully tested in the Amazon RDS and AWS EC2 environment (Linux). This topic contains important tasks to consider before installing SharePlex into these cloud services.

Amazon RDS checklist

The Amazon RDS service does not allow subscribers to access the operating system level of their deployments, so SharePlex cannot be installed on the RDS server. However, SharePlex can be installed outside the cloud and configured to connect to the cloud database through TNS.

Requirement Completed? (Y/N)

Decide where SharePlex Post processes will reside.

You can install SharePlex to connect to a database in an RDS cloud in either of these ways:

  • Use the on-premise source server to run both the source and target SharePlex components. In this setup, all of the SharePlex replication processes, including the Post processes, and all of the SharePlex queues exist on the source server. SharePlex connects through TNS to the RDS database. In a high-volume transactional environment, the buildup of data in the post queues and the presence of multiple Post processes may generate unacceptable overhead for a production system. In that case, you should use an intermediate server.

  • Use an on-premise intermediate server as the target component. In this setup, only the Capture, Read, and Export processes, with the export queue, run on the source server (the same as they do in non-cloud installations). The Post process and post queues run on the intermediate server and connect through TNS to the RDS database. This method removes most of the replication overhead from the source server.

Consider these alternatives and allocate the appropriate resources based on your chosen method of implementing SharePlex on RDS.

 

Amazon EC2 checklist

Unlike the Amazon RDS service, the EC2 service allows you access to the operating system and control over storage. SharePlex is installed and configured in the normal manner on the EC2 service, just as you would do it on a local server.

This checklist highlights the best practices that apply directly to installing SharePlex in the EC2 environment. In addition to completing these requirements, review and complete the other checklist requirements in this documentation.

Install on EBS.

An Amazon Elastic Block Storage (EBS) volume is persistent storage, whereas the default Amazon storage is non-persistent and data is lost when the instance shuts down. EBS volumes also provide better performance. Minimum size for a volume is 1GB.

 

Use multiple EBS volumes for best performance.

To optimize disk performance, create multiple EBS volumes and combine them by using software RAID. According to benchmarks, the optimal number of EBS volumes is 8.

 

Assign Elastic IP addresses

Amazon Elastic IP addresses are static, which satisfy SharePlex requirements. An Elastic IP must be created and assigned to both the source and target machines that will be used with SharePlex.
