Azure Service Fabric, how would you design and implement a fault-tolerant and highly available microservices architecture that ensures minimal downtime during updates and maintenance

Question

Problem Description: I am currently working on designing a fault-tolerant micro services architecture using Azure Service Fabric. The goal is to ensure minimal downtime during updates and maintenance while optimizing for resource utilization and scalability. However, I've encountered challenges in achieving the desired level of fault tolerance and maintaining high availability.

Hi, @Nikunj Khunt

It looks like you want to ask about: How would I architect a highly resilient, high availability, resource optimized microservice using Azure Service Fabric? Here is some solution from my side:

1. Service Partitioning:

• Consider the data and communication patterns of your microservices to determine the appropriate partitioning strategy. For stateful services, choose a partitioning key that evenly distributes data and requests.
• Service Fabric provides different partitioning strategies, such as singleton, named, and range partitioning. Choose the one that aligns with your application's requirements.

1. Replication and Availability:

• Configure the replication settings for your stateful services based on your desired level of availability and durability. Options include primary-only, synchronous, and asynchronous replication.
• Understand the impact of quorum-based systems on availability. A majority of replicas must be available for a service to remain operational.

1. Load Balancing:

• Service Fabric includes built-in load balancers for stateless services. Configure load balancing policies, such as round-robin or custom policies based on service metrics.
• For stateful services, use the Service Fabric Reverse Proxy to
