Azure BizTalk Services offers several editions. Use this article to determine which edition is right for your scenario and business needs.
Can create and manage Hybrid Connections. A Hybrid Connection is an easy way to connect an Azure website to an on-premises system, like SQL Server.
Includes Hybrid Connections, EAI and EDI message processing with an easy-to-use trading partner management portal, and support for common EDI schemas and rich EDI processing over X12 and AS2. Can create common EAI scenarios connecting services in the cloud with any HTTP/S, REST, FTP, WCF and SFTP protocols to read and write messages. Utilize connectivity to on-premises LOB systems with ready-to-use SAP, Oracle eBusiness, Oracle DB, Siebel, and SQL Server adapters. Use a developer centric environment with Visual Studio tools for easy development and deployment. Limited to development and test purposes only with no Service Level Agreement (SLA).
Includes most of the Developer capabilities with increases in Hybrid Connections, EAI bridges, EDI Agreements, and BizTalk Adapter Pack connections. Also offers high availability, and the option to scale with a Service Level Agreement (SLA).
Includes all the Basic capabilities with increases in Hybrid Connections, EAI bridges, EDI Agreements, and BizTalk Adapter Pack connections. Also offers high availability, and the option to scale with a Service Level Agreement (SLA).
Includes all the Standard capabilities with increases in Hybrid Connections, EAI bridges, EDI Agreements, and BizTalk Adapter Pack connections. Also includes archiving, high availability, and the option to scale with a Service Level Agreement (SLA).

For resiliency against hardware failures, High Availability implies having multiple VMs within a single BizTalk Unit.
A "unit" is the atomic level of an Azure BizTalk Services deployment. Each edition comes with a unit that has different compute capacity and memory. For example, a Basic unit has more compute than Developer, Standard has more compute than Basic, and so on. When you scale a BizTalk Service, you scale in terms of units.
BizTalk Services provides a true Platform-as-a-Service (PaaS) architecture for building integration solutions in the cloud. With the PaaS model, you focus completely on the application logic and leave all of the infrastructure management to Microsoft, including:
BizTalk Server on Azure Virtual Machines provides an Infrastructure-as-a-Service (IaaS) architecture. You create virtual machines and configure them exactly like your on-premises environment, making it easier to run existing applications in the cloud with no code changes. With IaaS, you are still responsible for configuring the virtual machines, managing the virtual machines (for example, installing software and OS patches), and architecting the application for high availability.
If you are looking at building new integration solutions that minimize your infrastructure management effort, use BizTalk Services. If you are looking to quickly migrate your existing BizTalk solutions or looking for an on-demand environment to develop and test BizTalk Server applications, use BizTalk Server on an Azure Virtual Machine.
The BizTalk Adapter Service is used by an Azure BizTalk Service. The BizTalk Adapter Service uses the BizTalk Adapter Pack to connect to an on-premises Line of Business (LOB) system. A Hybrid Connection provides an easy and convenient way to connect Azure applications, like the Web Apps feature in Azure App Service and Azure Mobile Services, to an on-premises resource.
The Hybrid Connection cost per unit depends on the BizTalk Services edition. Simply put, costs depend on how much data you transfer. For example, transferring 10 GB data daily costs less than transferring 100 GB daily. Use the Pricing Calculator for BizTalk Services to determine specific costs. Typically, the limits are enforced daily. If you exceed the limit, any overage is charged at the rate of $1 per GB.
Each agreement comprises of two different bridges: a send side communication bridge and a receive side communication bridge.
You are not able to deploy any new bridges or create any new agreements. To deploy more, you need to scale up to more units of the BizTalk service, or upgrade to a higher edition.
Use the backup and restore flow for migrating from one tier to another. Only some migration paths are supported. Refer to BizTalk Services: Backup and Restore for more details about the supported migration paths.
Yes, the BizTalk Adapter Service with the BizTalk Adapter Pack are included with the Azure BizTalk Services SDK download.
