Q

What is the role of Reliable Actors in Service Fabric?

A

Reliable Actors is a framework for building distributed, stateful microservices that manage their own state.

21
Q

What are Service Fabric Applications?

A

Service Fabric applications are collections of microservices that are deployed and managed together.

22
Q

What types of microservices can run in Service Fabric?

A

It supports stateless and stateful microservices, containers, and .NET-based services.

23
Q

How does Service Fabric ensure consistency in stateful services?

A

It ensures consistency through strong state replication using Reliable Collections.

24
Q

How is security implemented in Service Fabric clusters?

A

Security is implemented through certificate-based authentication, Azure Entra ID integration, and role-based access control.

25
Q

How does Service Fabric integrate with Azure Kubernetes Service (AKS)?

A

It integrates with AKS to orchestrate and manage containerized workloads.

26
Q

What is the Service Fabric Naming Service?

A

The Naming Service resolves and routes requests to the correct service within the cluster.

27
Q

What is a Service Fabric Node?

A

A node is a physical or virtual machine that is part of the Service Fabric cluster, running one or more services.

28
Q

How does Service Fabric ensure fault tolerance?

A

It ensures fault tolerance through replication and partitioning, spreading services across multiple nodes.

29
Q

How does Service Fabric handle service upgrades?

A
