Will serve as a base for defining rules for tendering process
Should include current IT inventory
Functional analysis of deployed applications
Libraries and their versions
Functional requirements of existing applications (for instance smartcard support)
The same for projected applications that are to be run in cloud
Performance requirements
Certain cloud implementations provide power-per-vm performance worse than
baremetal hardware
COST ANALYSISCOST ANALYSIS
HOW MUCHHOW MUCH
Based on IT assesment various vendors whose product match the needs are picked
Predefined cost mentioned on web pages, etc. is not fixed and many times can be dealt to
much lower
HW cost
Maintenance cost
Someone has to maintain HW and software, updates, outages, SLA
RISK ANALYSISRISK ANALYSIS
WHEN SOMETHING GOES WRONGWHEN SOMETHING GOES WRONG
HW
Estimate risk of fault for cloud components
Example:
Hard drive has a projected fault rate of 2% ( depends on vendor:
), if your cloud consists of 40 TB of disk space in 512 MB drives (~80 drives)
you'll annually lose almost 2 drives
SW
Each upgrade poses risk
Enterprise applications show risk charts based on codebase changes
Includes projected steps to minimize risks, or inventory of accepted risk factors
