@Bhalchandra Ramchan Patil Thank you for reaching out to Microsoft Q&A.
As given here in the Azure SSIS document, Use an Azure SQL Database server with IP firewall rules/virtual network service endpoints or a managed instance with private endpoint to host SSISDB.
You can use a service endpoint if using Azure SQL Database server and not a private endpoint. The difference between a service endpoint and private endpoint access is as follows:
*Azure Private Link (Private Endpoint) allows you to access Azure PaaS services over Private IP address within the VNet. It gets a new private IP on your VNet. When you send traffic to PaaS resource, it will always ensure traffic stays within your VNet.
Azure Service Endpoint provides secure and direct connectivity to Azure PaaS services over an optimized route over the Azure backbone network. Traffic still left your VNet and hit the public endpoint of PaaS service.
Access:
Service endpoint — It remains a publicly routable IP address.
Private endpoint — It is a private IP in the address space of the virtual network where the private endpoint is configured.*
