Recent Research Issues

Performance efficiency of cloud is a recent research

topic [1]

Very little testing done with open

source cloud standards [2]

Little bug to feature tests [3]

No practical implementation of the metrics[4]

Project Initiation Phase [8]:

Si = ∑Ni=1 (fOi)

•Test fitness

•Scope denoted by S

•Objective denoted by O

Presentation 601 12

Project Planning Phase

Risk management Planning

Communications Planning

Privileged user access

Identifying inappropriate

activities

Procedures of moving data to

a new environment

Reports, documents, DOTproject

Team meetings

Project Planning Phase

Presentation 601 13

Project Execution Phase

Availability [8]:

A= (UT in seconds ÷TT in seconds) × 100%

A = (7776000 ÷ 7711200) × 100% 

Therefore A = 99.17%

Data Security [8]:

DS = (DA ÷ TA) ×100%

Excepted range: 85%
