We're looking to migrate our application into AWS cloud entirely. It has come to our notice that it might not be possible to continue using the existing Oracle 19C Database links with external components if we're migrating to AWS Cloud.
Is there an alternate solution for maintaining connectivity with an external component's database? (we're the consumers here) Also, on a side note, the producer component is currently on an Oracle database; not AWS cloud.
Any inputs will be greatly appreciated. Thanks in advance!

We are currently setting up AWS hosting for our Web Application.
This Laravel Web Application will have a Schema per company that registers, meaning it will have a large sized mySql server.
I have gone through the motions of setting up a VPC with EC2 instances and and RDS for this mySql server.
However we are currently looking at using Laravel Forge as a tool to host.
What Forge does differently is that it includes the mySql Server on the EC2 instance not on an RDS.
The question I have come to ask here is, what are the implications if any of having the mySql server on the EC2 instance rather then an RDS.
Would there be performance issues?
Is it better practice to have an RDS?
Or is Forges out the box way of packaging this all together on an EC2 server fine?
By running this on an EC2 instance you will taking more of the responsibility of managing the database, not just installation but also patching, backups, recovery. Harder to maintain functionality such as replication and HA will also be on you to implement and monitor.
By running on RDS AWS is going to take the heavy lifting of this and implement a best practice version of MySQL which offers the flexibility of allowing you to run a MySQL stack in the cloud without having to really think about the implementation details under the hood other than deciding do you want it to be HA and how many replicas do you want.
In saying this by using RDS you're also giving up the ability to run it however you want, you are limited to the versions of the database that RDS supports (although this is now quite soon after release). In addition not all plugins or extensions will be active so check this functionality before deciding.
I am looking for scope where i can send data from oracle db to AWS Data exchange without any manual intervention?
In January 2022, AWS Data Exchange launched support for data sets backed by Amazon Redshift; the same guide referenced by John Rotenstein, above, shows you how you can create a data set using Amazon Redshift datashares. If you are able to move data from the Oracle database to Amazon Redshift, this option may work for you.
AWS Data Exchange just announced a preview of data sets using AWS Lake Formation, which allows you to share data from your Lake Formation data lake, which has support for Oracle databases running in Amazon Relational Database Service (RDS) or hosted in Amazon Elastic Compute Cloud (EC2). Steps to create this kind of product can be found here.
We need to migrate an Oracle DB from Azure VM to AWS RDS Aurora. And we have a checklist that what are the things we have to take care while doing migration from Oracle to Aurora.
But, what would be the best approach to do the migration. i.e., Migrate Azure Oracle VM to AWS EC2 and then, migrate to RDS. Or Migrate directly from Azure VM to AWS RDS Aurora using any Azure service(s), DMS, Datapump, SCT, something like that.
(I am not familiar with Azure DMS / DB related services)
I would go direct from Azure Oracle RM to the AWS RDS.
For the tool take a look at using the AWS Database Migration Service (DMS). It lets you connect to your source database (Azure Oracle) to your target database (AWS RDS For Oracle). AWS DMS handles creating the schema and tables in the target database.
The DMS deploys on dedicated VMs for you migration and is priced based on the size of the EC2 instance you will need from a t2.micro ($0.43/day) to a r4.8xlarge ($80/day + storage cost) and everything in between Data transfer into DMS is free and transfer to an RDS in the same AZ (availability zone) as the DMS is free.
A few features that makes the DMS nice include:
Continuous Data Replication: Once your initial migration is completed it can continue to replicate the data until you are ready to make the switch. This is nice because you do your migration ahead of time and have plenty of time for verification before you switch the application over.
Schema Conversion Tool: Not useful in your case but if you where migrating from to a different database such as Oracle to Aurora it would handle the schema for you.

I'm trying to migrate GCP instances to AWS, I have been searching for the solution but didn't find any references. Could you please help me with this.
The OS are customized differently in different cloud, so you can only migrate files and applications, by using Cloud Storage or AWS S3 as the bridge to migration files
While for the applications, you're recommended to build from scratch, but it highly depends on what exactly you want to migrate
I have an application that we are currently running on a number of co-located servers and I'm interested in moving everything to the cloud.
I have a legacy application running Postgres and its replacement application using MySql as its data store. I'm interested in moving to EC2 and looking to do this as pain free as possible. I was planning on using Amazon RDS for the MySql data store but am looking for options for the Postgres install.
I know that Heroku is built on top of EC2 and has Postres support and was wondering
Has anyone had any experience accessing a Heroku Postgres database from an application running in EC2. Comments on Performance, Reliability ease of Administration
The other alternative is to install Postgres on EC2 with EBS volumes but I've heard mixed reviews on performance, reliablitity and ease of administration.
Thanks in advance, any experience and suggestions would be greatly appreciated.
I've done this with several colocated boxes on the east coast. Heroku actually has a completely independent service: Heroku Postgres, which is built for this specific use case. The databases you create are all independent (not related to any Heroku apps).
