Logic Apps

Basic Information

Microsoft Logic Apps is a cloud-based platform-as-a-service (PaaS) for building and running automated workflows that integrate apps, data, systems, and services across enterprises or organizations. It operates under a continuous delivery model, meaning there isn't a fixed version number like traditional software, but rather ongoing updates and improvements.

• Model: Azure Logic Apps (Consumption and Standard plans), Hybrid Deployment Model.
• Version: Continuously updated. Standard Logic Apps runtime currently runs on .NET 6, with migration to .NET 8 expected by March 31, 2025. Node 18 LTS is supported.
• Release Date: General Availability (GA) was July 27, 2016. Logic Apps Standard GA was announced in 2021. The Hybrid Deployment Model reached GA on June 12, 2025.
• Minimum Requirements: As a fully managed cloud service, there are no specific hardware or operating system requirements for the Logic Apps service itself. Client-side access for management and development typically requires a modern web browser for the Azure portal and Visual Studio Code for local development.
• Supported Operating Systems: N/A for the service. Client-side access is OS-agnostic, relying on web browser compatibility.
• Latest Stable Version: N/A due to continuous delivery. The underlying runtime for Standard Logic Apps is transitioning from .NET 6 to .NET 8.
• End of Support Date:
  • Integration Service Environment (ISE) reached end of life on August 31, 2024. Users are strongly encouraged to migrate to Logic Apps Standard.
  • Support for .NET 6 in Logic Apps Standard will continue until the migration to .NET 8 is completed, anticipated by March 31, 2025.
  • Node 16 LTS support ended on September 11, 2023.
• End of Life Date: Integration Service Environment (ISE) reached end of life on August 31, 2024.
• Auto-Update Expiration Date: N/A. As a managed service, updates are automatically applied by Microsoft.
• License Type: Consumption Logic Apps utilize a pay-as-you-go, consumption-based pricing model. Standard Logic Apps offer per-action or integration account-based licensing. The Hybrid Deployment Model requires customers to manage their own Kubernetes infrastructure and SQL Server licenses.
• Deployment Model: Primarily cloud-based (PaaS/SaaS) for both Consumption and Standard plans. Standard Logic Apps also support a hybrid deployment model, allowing workflows to run on customer-managed infrastructure (on-premises, private cloud, or other public clouds) using Kubernetes.

Technical Requirements

As a serverless cloud service, Microsoft Logic Apps abstracts away the underlying infrastructure. Therefore, traditional hardware specifications like RAM, processor, storage, display, and ports are not directly applicable to the service itself. Microsoft manages these resources within the Azure environment.

• RAM: N/A (managed by Azure).
• Processor: N/A (managed by Azure).
• Storage: N/A (managed by Azure).
• Display: N/A (client-side requirement for management portal).
• Ports: N/A (managed by Azure).
• Operating System: N/A for the service. Client-side access for management and development is typically done through a web browser, making it compatible with most modern operating systems. For local development, Visual Studio Code is a common tool.

Analysis of Technical Requirements

The primary advantage of Logic Apps being a serverless cloud service is that users are freed from managing infrastructure. Microsoft handles all technical requirements related to the underlying compute, storage, and networking. This allows organizations to focus on workflow design and integration logic rather than infrastructure provisioning and maintenance. For the Hybrid Deployment Model, customers are responsible for providing and managing their Kubernetes environment and a SQL Server instance for runtime data storage.

Support & Compatibility

Microsoft Logic Apps offers robust support and extensive compatibility, primarily through its continuous update model and a rich ecosystem of connectors.

• Latest Version: The service is continuously updated. Standard Logic Apps runtime is currently migrating to .NET 8, and Node 18 LTS is supported for custom code.
• OS Support: N/A for the service itself. Client-side management and development are supported across various operating systems via web browsers and development tools like Visual Studio Code.
• End of Support Date:
  • The Integration Service Environment (ISE) was retired on August 31, 2024, requiring migration to Logic Apps Standard.
  • .NET 6 support for Logic Apps Standard will conclude by March 31, 2025, with a transition to .NET 8.
• Localization: Microsoft Azure services, including Logic Apps, are available in multiple languages, supporting a global user base.
• Available Drivers: Logic Apps does not use traditional drivers. Instead, it offers a vast library of over 600 pre-built connectors for seamless integration with various Azure services, Microsoft 365, on-premises systems, and third-party applications. Custom connectors can also be developed for specific integration needs.

Analysis of Overall Support & Compatibility Status

Microsoft Logic Apps benefits from continuous support and updates as part of the Azure ecosystem. The extensive library of connectors is a significant strength, enabling broad compatibility with diverse systems and applications without requiring custom code for many integrations. The retirement of ISE and the migration to Logic Apps Standard highlight Microsoft's commitment to evolving the platform with improved performance and features. Users should be aware of runtime dependencies like .NET and Node.js versions for Standard Logic Apps to ensure continued support.

Security Status

Microsoft Logic Apps leverages the comprehensive security framework of Azure, providing robust protection for workflows and data.

• Security Features:
  • Data Encryption: Data is encrypted both at rest (using Microsoft-managed keys in Azure Storage, with customer-managed keys available for Standard Logic Apps with customer-managed storage) and in transit (using Transport Layer Security (TLS) 1.2 and HTTPS).
  • Access Control: Integrates with Azure Active Directory (AAD) and utilizes Role-Based Access Control (RBAC) for fine-grained permissions management.
  • Authentication Methods: Supports OAuth 2.0 with Microsoft Entra ID, Managed Identities, Shared Access Signatures (SAS) keys, and API keys.
  • Managed Identities: Provides secure authentication to Azure services without managing credentials directly.
  • Secrets Management: Integration with Azure Key Vault for securely storing and managing sensitive information like API keys and connection strings.
  • Network Security: Supports IP address restrictions, Azure Virtual Network (VNet) integration, and Private Link for secure, isolated communication.
  • Secure Designer: Options to secure inputs and outputs within the workflow designer.
  • API Management Integration: Can be exposed through Azure API Management to act as a security gateway, providing additional controls like rate limiting and advanced authentication.
  • Monitoring and Threat Detection: Leverages Azure Security Center and Azure Monitor for continuous security posture monitoring, threat detection, and incident response.

• Certifications: As part of Microsoft Azure, Logic Apps adheres to numerous global, industry-specific, and regional compliance standards and certifications, including GDPR, HIPAA, and ISO 27001.
• Encryption Support: Comprehensive encryption for data at rest and in transit, with TLS 1.2 enforced for inbound calls.
• Authentication Methods: OAuth 2.0 with Microsoft Entra ID, Managed Identities, SAS keys, and API keys.
• General Recommendations: Microsoft recommends using Microsoft Entra ID with managed identities for optimal security. Implementing RBAC, storing secrets in Azure Key Vault, restricting IP addresses, and utilizing Azure API Management are also advised.

Analysis on the Overall Security Rating

Microsoft Logic Apps offers a high level of security by inheriting the robust security features of the Azure platform. Data is protected through encryption both at rest and in transit. Strong access control mechanisms, including Azure AD integration and RBAC, ensure that only authorized users and services can interact with workflows and data. The support for managed identities and Azure Key Vault significantly enhances credential management. Overall, Logic Apps provides a secure environment for integrating and automating business processes, with continuous monitoring and compliance with major industry standards.
