By:Richard Appiah

2

Main Objective:

To conduct a survey on current practices regarding the use of the Cloud as a resource or platform for software development.

Some Known Benefits and Drawbacks

Benefits Drawbacks

Higher Computing Power Numerous APIs to master

Global Project Tracking in Real Time

Difficult to Transfer Project Knowledge Among Teams

High Reliability Cultural, Geographic, Jurisdiction Challenges

Cheaper to Test SW

24-Hour Development Cycle

3

Motivation for Cloud-based SW Development

1. The support for global software solutions

2. Easy ways to achieve better Business-Technology alignment

3. Ease of code reusability

4. Reliability and Extendibility of the Cloud

4

Sample Architectures

A. Generic Cloud-based Agile SW Development Model

5

B. AWS-Inspired Cloud-based SDLC Architecture: TAPTIN

6

C. The OpenCloudware SDLC Architecture: - SE Platform for Collaborative Development of Distributed Application.

7

D. The WSO2 App Factory Architecture: A Multi-Tenant, Elastic, Self-Servicing Enterprise DevOps Platform, for Team Collaboration.

Current Technological Trends

2 Main Areas Highlighted:

i. Domain Specific Languages (DSLs)

ii. Innovative SDLC Architectures on the Cloud

9

Role Distribution Between SW Developer & Cloud Providers

The following guidelines are recommended:

1. All major phases of the work must be done in conjunction with representatives from the cloud provider(s)

2. Roles must be clearly stated – i.e. developers’ and cloud providers’

3. The following tabulated separation of duties is recommended:
