Optimize code and application performance by conducting regular code reviews, implementing performance testing, and monitoring application performance to identify and fix resource-hungry areas. 7. Implement cloud-based solutions and leverage cloud services to dynamically allocate resources based on workload demands. 8. Utilize caching mechanisms and content delivery networks (CDNs) to reduce the load on servers and improve response times. 9. Implement load balancing and traffic management techniques to distribute workloads evenly across servers, ensuring efficient resource utilization. 10. Regularly perform capacity planning and forecasting to anticipate resource requirements and optimize resource allocation in advance.
Detailed Answer:
Explain the concept of progressive delivery.
Summary:
Progressive delivery is a software development approach that aims to release new features and updates gradually rather than all at once. It allows for controlled and monitored rollouts, enabling teams to gather feedback, identify issues, and make necessary adjustments before wider deployment. This helps mitigate risks and ensure a smooth user experience.
