Dynamic Capacity Planning via HTTP Response Header Expiration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current capacity planning for web services is often manual and static, failing to adapt dynamically to real-time workload changes, which can lead to inefficiencies and performance issues.
Innovation Solution
A system and method for automated, dynamic capacity planning using HTTP header response fields, where a web server automatically determines server workload statistics, calculates new expiration values for HTTP header response fields, and updates configuration files to optimize caching and resource allocation in response to changing workloads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual and static capacity planning is used for web services, then implementation simplicity is maintained, but adaptability to real-time workload changes deteriorates
Solution Approach 1:
The patent implements dynamic capacity planning by automatically adjusting HTTP header expiration values based on real-time server workload statistics. The system transitions from static manual configuration to dynamic automated adjustment, where caching parameters adapt continuously to changing workload conditions without manual intervention
Solution Approach 2:
The system enables self-service capacity planning by automatically monitoring server workload and adjusting caching expiration values without requiring manual capacity planning activities. The web server autonomously determines workload statistics and modifies HTTP headers to optimize performance based on current conditions
2Adaptability or versatility
If automated dynamic capacity planning is implemented, then adaptability to workload changes is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs self-service capacity planning by automatically monitoring server workload statistics and adjusting HTTP header expiration values without requiring manual capacity planning activities. The web server autonomously determines workload conditions and modifies caching parameters to optimize performance
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring server workload statistics and using this information to dynamically adjust HTTP header expiration values. The closed-loop feedback ensures caching parameters remain optimized based on real-time server conditions
3Productivity
If static caching expiration values are used, then configuration simplicity is maintained, but productivity and performance deteriorate under varying workloads
Solution Approach 1:
The patent transforms static caching configuration into dynamic adaptive caching by automatically adjusting HTTP header expiration values based on real-time server workload. The system optimizes website performance by adapting caching parameters to current workload conditions rather than using fixed values
Solution Approach 2:
The system changes caching parameters dynamically by modifying HTTP header expiration values based on server workload statistics. The expiration values are adjusted as parameters respond to workload conditions, optimizing performance without manual configuration changes
Data Source
AI summary
A system, computer-readable media and computer-implemented method for automated, dynamic capacity planning using HTTP response header fields. The computer-implemented method includes: automatically determining a server workload statistic relating to operation of a server, the server being configured to serve a content item in response to HTTP-formatted requests; automatically determining an expiration value based at least in part on the workload server statistic; automatically updating a configuration file corresponding to the content item with the expiration value; receiving a request for the content item from a requesting device; automatically accessing the configuration file and generating a HTTP-formatted response header incorporating the expiration value; and, automatically transmitting the HTTP-formatted response header and the content item in response to the request.
