![]() Service Fabric uses XML files for application and service definition. Service Fabric and AKS have different application and service manifest file types and constructs. For more information, see Introduction to the Distributed Application Runtime. The Distributed Application Runtime (Dapr) provides APIs that simplify microservice connectivity. ![]() You can replace Service Fabric Reliable Collections with the Dapr state management building block. When you migrate a workload from Service Fabric to AKS, you can replace Service Fabric Reliable Actors with the Dapr actors building block. You can also use Traefik on Service Fabric.īYO ingress controllers (open source and commercial) that use platform-managed public or internal load balancers, like NGINX ingress controller and Application Gateway Ingress Controller ![]() It helps microservices that run in a Service Fabric cluster discover and communicate with other services that have HTTP endpoints. Support for multiple network plug-ins (Azure CNI, kubenet, BYOCNI), network policies (Azure, Calico), and ingress controllers (Application Gateway Ingress Controller, NGINX, and more)Ī reverse proxy that's built in to Service Fabric. Support for various storage systems, like managed disks, Azure Files, and Azure Blob Storage via CSI Storage classes, persistent volume, and persistent volume claims WCF-based communication stack for Reliable Services Native support for Reliable Services and Reliable Actor pattern Virtual Machine Scale Sets, Azure managed Virtual Machine Scale Sets, customer configured Support for both stateless and stateful workloads The following table compares the capabilities and features of the two hosting platforms. To move your workload from Service Fabric to AKS, you need to understand the differences in the underlying infrastructure so you can confidently migrate your containerized applications. Azure manages the Kubernetes master nodes, so you manage and maintain only the agent nodes. Because AKS is a hosted Kubernetes service, Azure handles critical tasks like infrastructure health monitoring and maintenance. All underlying resources for the cluster are abstracted away and managed by Azure.ĪKS simplifies deploying a managed Kubernetes cluster in Azure by offloading the operational overhead to Azure. The encapsulation model for Service Fabric managed clusters consists of a single managed cluster resource. It's your responsibility to make sure that these resources are correctly configured. These resources include a virtual machine scale set for each cluster node type, network security groups, and load balancers. When you deploy a traditional Service Fabric cluster, as opposed to a managed cluster, you need to explicitly define a cluster resource together with a number of supporting resources in your Azure Resource Manager templates (ARM templates) or Bicep modules. Containers on AKS: AKS only supports containerization with Windows and Linux containers running on the container runtime containerd, which is managed automatically.īoth Service Fabric and AKS offer integrations with other Azure services, including Azure Pipelines, Azure Monitor, Azure Key Vault, and Azure Active Directory (Azure AD).Programming models: Service Fabric supports multiple ways to write and manage your services, including Linux and Windows containers, Reliable Services, Reliable Actors, ASP.NET Core, and guest executables.Service Fabric provides support for several programming models, whereas AKS supports only containers. This section highlights notable similarities and differences that are relevant to migration.īoth Service Fabric and AKS are container orchestrators. To start, review this article that compares the two platforms, alongside other Azure compute services. The article also provides best practices for you to consider during migration. The article assumes that you're familiar with Service Fabric but are interested in learning how its features and functionality compare to those of AKS. This article describes how to migrate containerized apps from Azure Service Fabric to AKS. Many organizations are using AKS as their primary infrastructure platform and are transitioning workloads hosted on other platforms to AKS. AKS is a hosted Kubernetes service that simplifies application deployments via Kubernetes by managing the control plane to provide core services for application workloads. There's no one-size-fits-all solution for apps, but organizations often find that Azure Kubernetes Service (AKS) meets the requirements for many of their containerized applications. ![]() As technologies continue to evolve, organizations are evaluating the many containerized app platforms that are available in the public cloud. Many organizations have moved to containerized apps as part of a push towards adopting modern app development, maintenance best practices, and cloud-native architectures. ![]()
