❤️❤️❤️❤️❤️❤️❤️

Great! You’ve reached a stage where you’re eager to explore Appian at a deeper level. Understanding how the infrastructure works can make you stand out from the rest of the team. Let’s get started!

The Appian Enterprise Architecture is a low-code platform for automating and transforming mission-critical business processes. It is a unified platform that provides everything you need to build, deploy, and manage enterprise applications, including:

• Process automation: Appian allows you to automate any business process, from simple workflows to complex case management.
• Low-code development: Appian’s low-code development environment makes it easy for anyone to build enterprise applications, even if they don’t have coding experience.
• Enterprise-grade security, scalability, and reliability: Appian is built on a scalable and reliable platform that can handle the most demanding enterprise workloads.

Components of the Appian Enterprise Architecture

The Appian Enterprise Architecture is composed of the following components:

• Front-end server: The front-end server hosts the Appian web application and provides the user interface for interacting with Appian applications.
• Backend engines: The backend engines are responsible for executing process models, managing data, and providing other services.
• Database: The Appian database stores Appian internal data and metadata, as well as any additional relational databases that are used to store Appian business data.
• Data service: The data service provides a unified interface for accessing all Appian data sources.
• Messaging service: The messaging service relays messages between different components of Appian.

Communication between components

The Appian Enterprise Architecture uses a variety of protocols to communicate between components. The following table lists some of the most common protocols:

• HTTP: HTTP is used to communicate between the front-end server and the back-end engines.
• AMQP: AMQP is used to communicate between the messaging service and the backend engines.
• JDBC: JDBC is used to communicate between the data service and the Appian database.

Security

The Appian Enterprise Architecture provides enterprise-grade security. Appian supports a variety of authentication and authorization mechanisms, including OAuth2, SAML, and LDAP. Appian also provides a variety of security features to protect your data, such as data encryption, role-based access control, and audit logging.

Scalability and reliability

The Appian Enterprise Architecture is designed to be scalable and reliable. The backend engines can be scaled horizontally to handle the increased workload. The Appian database can be scaled up to meet the needs of large and complex deployments.

Deployment options

The Appian Enterprise Architecture can be deployed in a variety of ways, including:

• On-premises: Appian can be deployed on-premises in your own data center.
• Cloud: Appian can be deployed in the cloud on a platform such as Amazon Web Services (AWS) or Microsoft Azure.
• Hybrid: Appian can be deployed in a hybrid environment, with some components deployed on-premises and others deployed in the cloud.
