The AS2 communication protocol is one of the most advanced processes. It enables a handshake with the source and target systems using certificates. It is the most secure way of communicating between two systems. It is an advantage. We can do a lot of message routing. If we want to handle large data, we can put the data into different patterns to process it. We can do it through sequential convoy or parallel convoy orchestration. BizTalk comes with SQL Server. We can load temporary data in the database and use the batch process from BizTalk. It is an added advantage. Creating agreements is a manual job, but it's quite easy in BizTalk. Even a fresh college graduate can configure AS2 certificates and partner profiles and communicate with other systems. It is easy.
