Cloud Computing: Vendors Selection parameters and Comparison of Deployment Model..

In my previous blog, http://www.infosysblogs.com/thought-floor/2013/09/risk_assessment_and_mitigation.html,

we explored the risks associated with Cloud Deployment and ways to mitigate them. Now let us compare the different deployment models i.e. Public Cloud, Private Cloud and Hybrid Cloud. Also we will try to explore the Parameters which can help in comparing the Cloud Providers and select the best one.

Vendor Selection Criteria.

Note: The scores are indicative. In this Example Vendor 2 has a better Score and hence correct choice.

 

Vendors/Parameters Vendor 1 Vendor 2
Level of Security (vulnerability, physical, personnel, attacks) 8 8
Level of data protection (while it is at rest and while it is moving) 7 8
Interoperability, Compatibility with other cloud vendors 8 8
Scalability offered 5 7
Cost per Unit 8 9
SLA offered 9 6
Ease of access  4 4
Level of Redundancy 6 5
Vendor's expertise in cloud  3 8
Level of Support offered while moving to cloud 1 4
Level of support offered during the engagement 2 6
End of service support offered 3 9
Compatibility with customer's infrastructure 8 7
Degree of vendor lock-in 7 5
Compensation offered in case of a SLA breach/data leak/compliance 6 6
Level of control offered to customer 4 2
Quality of internet connectivity 5 7
Investigative support 2 9
Ease of provisioning and capacity management 3 5
Suitability for customer's application (system architecture) 7 6
Success in providing service to any enterprise 8 6
Level of 24/7 Customer support  4 4
Any provision for telecom specific Domain 6 4

TOTAL Score 126 150

 

 

Comparison of Deployment Model.

 

Deployment Model Public Cloud  Private Cloud Hybrid Cloud
       
Parameters      
Level of Abstraction High Low Moderate 
Tenancy Either a single-tenant (dedicated) or multi-tenant (shared) operating environment Single-tenant (dedicated) operating environment A combination of public and private cloud offerings that allow for transitive information exchange
Level of Security Low. No access to data in provider premise High. Full access to data is available  High. Full access to data is available 
Vendor Lock-in chances Depends upon the technology that the vendor uses High. Depends upon the technology used by provider. Depends upon the technology used by the vendor
Capital Expenditure Low. As most of the infrastructure is maintained by the provider High. The in-house infrastructure has to be prepared for deployment High
Operational Expenditure High. Continuous pay per usage charging  Moderate. Only one time setup charge is high Moderate 
Managed by: Third party Organization or third party Both Organizaiton and Third party
Level of Virtualization Depends upon the technology that the vendor uses It is basically providing intelligence over virtualization  Virtualization level is lower than that in private cloud
SLA Guarantee Difficult to Obtain Easier to Obtain and monitor  Easier to Obtain and monitor
Suitable for : SMB Enterprise Both
Data Privacy Low  High  Moderate 
Legal and compliant issues High since data may have to be stored on foreign land Low since data resides in our own data center Low since data resides in our own data center
Types of application Suitable Less mission critical application having less integration level Application dealing with highly confidential data  Application dealing with highly confidential data 
Infrastructure Owned by: Third party Organization or third party Both Organizaiton and Third party
