DEPLOYING ECOMMERCE SOLUTIONS WITH CLOUD AND OPEN SOURCE TECHNOLOGIES: HIGH AVAILABILITY APPLICATION MODELS

摘要

Purpose: This paper proposes High Availability (HA) Application Models for deploying eCommerce solutions leveraging open source and cloud computing technologies based on global best practices in production environment architecture for mission critical applications. Design/Methodology/Approach: The key functionality requirements of the production environment were identified and incorporated into the design of the HA models based on existing designs for Database replication, load balancing, monitoring and backups. The designs of Anicas (2015a) on production server setups were adopted and modified to design three (3) High Availability eCommerce Production Environment models. Findings: Recovery plan, load balancing and scaling were identified as the most critical components of HA systems. At least, two of these components were incorporated in each of the three (3) HA models with varied degree of feature implementation. Research limitations/implications: The HA models outline production environment features and recommend open source technologies that could be used to implement their functionality. Technical details on implementation or site security were not discussed. Practical implications: These models shall be very useful to system engineers working on eCommerce solution as they could adopt or modify the designs for implementation on their infrastructure. Originality/value: The HA models were modified to suit ecommerce solution requirements and outline essential components of Highly Available eCommerce solutions which could be valuable information for the system engineer or ecommerce solution expert.
