| Problem | Explanation | Solution |
|---|---|---|
| Provisioning | Lack of control on service instances unless each instance is a separate process | Provision separate hosts for each service instance or use containerization technologies like Docker or VMs to provide process-level or VM-level isolation |
| Isolation | Lack of isolation if several service instances share the same host | Thoroughly analyze the resource requirements of each service instance and plan resource allocation accordingly. Regularly monitor resource usage to identify any bottlenecks or imbalances and make adjustments as needed |
| Resource consumption | Resource contention and potential performance issues if one service instance consumes a disproportionate amount of resources | Implement load balancing mechanisms to distribute incoming requests evenly among service instances. Additionally, ensure fault tolerance by implementing redundancy and failover mechanisms to mitigate the impact of host or instance failures |
| Orchestration | Potential single point of failure if the host running multiple service instances fails | Use automation and orchestration tools to streamline the deployment and management of multiple service instances. Tools like Docker Swarm, Kubernetes, or cloud-based orchestration platforms can simplify the provisioning, scaling, and monitoring of service instances |
