retry mechanisms

Retry mechanisms are processes that automatically attempt to complete a failed task or operation again. These are used in software and network systems to handle temporary issues, ensuring that tasks are eventually completed without user intervention.

How can I optimize mobile app performance for handling network requests or API communication?

To optimize mobile app performance for handling network requests or API communication, you can follow these key steps:

1. Use efficient data serialization formats like JSON or Protocol Buffers to minimize data size and reduce network latency.
2. Implement caching mechanisms to store frequently requested data locally, reducing the need for repeated network requests.
3. Employ background threads or asynchronous programming techniques to offload network operations and prevent main UI thread blocking.
4. Minimize the number of network requests by combining multiple requests into batched or grouped requests.
5. Implement proper error handling and retry mechanisms to ensure robustness in handling network failures.

By following these steps, you can significantly improve the performance of your mobile app when communicating with APIs or handling network requests.

How do you handle server health checks and fault tolerance in backend systems?

Server health checks and fault tolerance play a vital role in ensuring the smooth operation of backend systems. Here are some key points to address the most frequently asked question:   Server Health Checks:   Regular monitoring of server metrics is crucial to identify any issues promptly. Implementing automated health checks using tools like Nagios or Grafana helps in checking the server’s overall status, availability, and performance.   **Nagios**: Nagios is a popular open-source monitoring tool that can perform various checks, including monitoring CPU, memory, disk usage, network connectivity, and more. It sends alerts or notifications when predefined thresholds are exceeded. **Grafana**: Grafana is another powerful tool that allows you to create customized dashboards to monitor and visualize server metrics. It integrates with various data sources and offers a wide range of visualization options.   Load balancers like NGINX or HAProxy are widely used to distribute incoming traffic across multiple servers. They continuously check the health of backend servers and exclude any unhealthy servers from
