How can you design a low-maintenance system?

It totally depends upon the level of operational overhead you need. Going Serverless is one option if you totally want to delegate the resource management overload to any cloud provider and if this is not the case you need to make sure that you have identified clear boundaries in your domain and the way data will come in and out of the system. Once done you can then define inter and intra service controls to reduce maintenance overhead.

Designing a low-maintenance system is like building a simple, cozy home. Start with clear needs and skip the extras. Prioritize what you use often and keep it streamlined. Think of it as decluttering your space for easier upkeep.

Design a low maintenance system should come up with a clean approach with limited problems to solve and that can extend. Sometimes over engineering makes systems hard to maintain, it's good to take time for a designing system instead of focusing to push the deliverables, if it takes 10 percent more bandwidth it should think in cleaner way

To build a strong and easy-to-maintain system, stick to good habits. - write clear code - test it well - keep helpful documentation - use tools like Git to track changes - set up automated processes for testing and deploying your code

Oftentimes we always focused on scalability but in the end we achieve scalability by adding more infrastructure. Always think about the application load vs infrastructure required to achieve that load. With the help of clear requirements of system and estimations of Data volumes, variety, velocity, concurrency & cost will help us to design our system. After analysing estimations we can choose right technology and scalability techniques.

- Try to use technologies that provide backwards compatibility support - Avoid cutting the edge - eliminate dependencies to keep it maintainable - use of automation where applicable - keep it simple stupid - keep reusability at hand

Focus on principles - KISS (Keep It Simple, Stupid) and YAGNI(You aren't gonna need it) to keep low maintenance system. Don't over-engineer the design, and build use cases and improvements iteratively.

Google's search engine is a quintessential example of a low-maintenance system design. To achieve this, Google employs a microservices architecture, allowing for the modular updating and maintenance of individual components without affecting the overall system. This architecture facilitates easy deployment of updates, bug fixes, and new features. Additionally, Google uses extensive automation for testing and deployment, significantly reducing manual intervention and the potential for human error. By leveraging scalable cloud infrastructure, Google ensures that its system can handle varying loads with minimal manual adjustment

Automate maintenance tasks: Use automation tools and scripts to automate routine maintenance tasks such as backups, monitoring, and software updates. This can reduce the amount of manual effort required to maintain your system and minimize the risk of human error. Monitor and analyze performance: Implement monitoring tools to track the performance of your system and identify potential issues. Use this data to optimize your system and proactively address maintenance issues before they become critical.
