FME Cloud runs on Amazon Web Services (AWS).Many 亚搏在线workflows that you will run on FME Cloud are likely to require a database.FME Cloud instances do ship with a PostGIS database that you can store your own data in,but for production workloads we strongly recommend using the AWS Relational Database Service (RDS) instead.RDS makes it very easy to set up,operate and scale a relational database in the cloud.You can launch a MySQL,Oracle,SQL Server (inc.SQL Server Spatial) and PostgreSQL (inc.PostGIS) database.
Advantages of using RDS over the FME Cloud PostGIS database:
Advantages of using RDS over on-premises database:
It is relatively simple to launch an RDS database,you will need an AWS account and then theAWS documentationdoes an excellent job of walking you through the process.For optimal performance place your database in the same region and availability zone (AZ) as the FME Cloud instance.You can find the region/AZ the FME Cloud instance is in by selecting an instance on the FME Cloud dashboard and then looking on the Details panel.
An RDS database behaves exactly like a normal relational database.You can therefore just use the relevant reader/writer to interact with it.One thing to be aware of on the AWS side is security groups.Each RDS instance is assigned to a security group which defines which ports are open to the outside world.You will need to ensure the port the database runs on is open and it is best practice to tie this to an IP rather than having it completely open.If you do want to tie it to the FME Cloud IP then you need to be aware of the fact the IP is not static.When you pause the instance it will be assigned a new IP.There is a workaround for this which is discussed inthis article.
