DTGOV Cloud Computing: Infrastructure and Platform Analysis Case Study

This case study examines DTGOV, a public company, and its transition to cloud computing. The company, with a history of providing IT services to the public sector, aims to optimize operations, reduce costs, and standardize infrastructure. The chosen solution involves Infrastructure as a Service (IaaS) using Amazon Web Services (AWS), including services like Amazon EC2, Route 53, CloudFront, S3, Elastic Beanstalk, RDS, and Elastic Search. The cloud architecture is detailed, covering front-end and back-end components, with a focus on data and application migration phases. The study also explores the benefits of cloud adoption for DTGOV, such as reduced investment, resource optimization, and enhanced disaster recovery. Furthermore, it compares Office 365 with on-premise applications and recommends the Platform as a Service (PaaS) model for SharePoint implementation. The case study concludes with recommendations for DTGOV's cloud strategy and references relevant research.

[Name and No] 12
RECOMMENDED Model for SharePoint
■ Cloud Delivery Models
– IaaS also known as Infrastructure as a Service
– PaaS also known as Platform as a Service
– SaaS also known as Software as a Service
■ PaaS is the Recommended Model
– Cost-effective in comparison with IaaS and SaaS
– Much less overheads and configurations compared to IaaS
– More controls and personalization options compared to SaaS
■ Issues in PaaS model
– Configuration and controls can be daunting compared to SaaS version which can be
effectively put to use from Day 1.
– Less secure compared to SaaS version if not properly secured
– The responsibility to secure and administer remains with the client compared to SaaS
version
