Cloud Computing Technology: DSI's OSDS Deployment Analysis Report

This report evaluates cloud computing technologies for the Department of Spatial Information (DSI) to migrate its Online Spatial Delivery System (OSDS). It examines the advantages and disadvantages of Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) for OSDS deployment, considering factors like scalability, security, and location independence. The report also explores different cloud deployment architectures, recommending a private cloud model for enhanced security and flexibility. Furthermore, it assesses cloud edge solutions and compares monolithic and microservice architectures, advocating for a microservice approach for OSDS due to its scalability, ability to handle updates, and potential to prevent cascading failures. The report concludes with a comprehensive analysis of cloud computing strategies tailored to DSI's specific needs and data sensitivity.
