A production application architecture is the blueprint for how an application will be deployed and operated in production. It defines the components of the application, their relationships, and how they will interact with each other. A well-designed production application architecture can help to ensure that the application is reliable, scalable, and secure.
Step-By-Step Explanation :
1. client/server request

client/server
|
- Developer Pushes Code to the Server: The developer pushes their code from a local repository to a server hosting the production environment.
- CI/CD Validates the Code: The code undergoes automated tests and validations to ensure quality and prevent regressions before proceeding to the next stage.
- Server Connections to External Storage or Databases: The server can connect to external storage or databases via a network, enabling secure and efficient communication.
- User Requests and Responses: Users make requests to the server, which responds either with static files (HTML, CSS, JS) or JSON data in API-based servers.
2. Vertical Scaling

Vertical scaling involves increasing the configuration of RAM and CPU on a single server to improve load time and decrease latency in the application.
Load time and latency are critical factors that impact the overall performance and responsiveness of an application. By upgrading the resources of a server, specifically increasing the RAM and CPU capacity, the server becomes capable of handling a higher workload and processing requests more efficiently.
3. Horizontal Scaling

Indeed, vertical scaling can have limitations, such as the potential for a single point of failure. Horizontal scaling, on the other hand, addresses this concern by distributing the workload across multiple servers. Rather than increasing the configuration of a single server, horizontal scaling involves adding more servers to the system, maintained and managed by a load balancer. This approach offers several advantages :
- Improved Reliability
- Scalability on Demand
- Enhanced Performance
- Redundancy & High Availability
4. External Services & API

In a production application architecture, a server often communicates with external API services and CDN servers to enhance functionality and content delivery. When integrating with external APIs, consider authentication, data exchange, error handling, and rate limiting. For CDN servers, configure caching, distribute static content, integrate with the application, and implement cache invalidation. These integrations improve performance, extend functionality, and provide a seamless user experience.
5. Logging Services

Logging services play a crucial role in capturing and storing activity logs in a production application architecture. Rather than storing logs directly on the server, they are typically sent to dedicated logging services.
- Importance : Logs provide valuable insights into application behavior and performance. They store information such as load time, latency, bandwidth, failures, and more. Analyzing logs helps developers troubleshoot issues, monitor system health, and optimize the application.
- Dedicated Logging Services:
- Logs are stored in specialized logging services rather than on the server.
- Logging services efficiently handle high volumes of log data and provide search and storage capabilities.
- Retrieving Logs:
- Logs can be easily accessed and analyzed from logging services.
- Logging services offer search and filtering options for efficient log retrieval.
6. Metrics & Alerts

- Metrics track server responsiveness, resource usage, and CPU efficiency.
- They provide data on how well the server is performing and utilizing resources.
- Proactive Issue Detection:
- Metrics enable proactive issue detection by monitoring critical server parameters.
- Thresholds are set to trigger alerts when metrics exceed predefined limits.
- Alerts notify developers about critical errors or when metrics reach predefined thresholds.
- Notifications are pushed to the appropriate channels for immediate attention and action.
In conclusion, designing a standard production application architecture requires careful consideration of various components and practices. By understanding the client/server request flow, optimizing vertical and horizontal scaling techniques, integrating with external API services and CDN servers, leveraging logging services, and monitoring metrics with alerts, developers can create a robust and efficient architecture. This enables improved load time, decreased latency, enhanced content delivery, proactive issue detection, and effective troubleshooting. By implementing these practices, developers can ensure a scalable, reliable, and high-performing production application architecture that meets the needs of modern applications and delivers a seamless user experience.
