Cloud computing is universally recognized as having the potential to drive greater agility, control and cost savings by providing on-demand access in a user centric environment. What IT is adding to it is a hybrid delivery model that includes a traditional IT, private and public cloud.
In this context, Cloud Management Platform provides a solution that manages cloud access, simplifies and unifies business operations, implements security and compliance, and provides an open, extensible and scalable infrastructure. The speed of delivery has increased dramatically with this new ability. Costs are reduced and control is passed back to the organization instead of the "shadow IT" and improves accountability.
We review what is meant by the open, extensible and scalable infrastructure.  Ideally, the management platform for the cloud should be optimized for heterogeneity, multi-hypervisor, multi-vendor environments and multiple public clouds. The adoption of OpenStack as the underlying technology and enabling optimized workload portability by implementing industry standards like TOSCA define openness. Flexibility for integration and extensibility comes from REST APIs with out-of-box integration and extensibility for custom environments enables an ecosystem to evolve.
 Heterogeneity with no - vendor lock-in  means the infrastructure is scalable. 
When we review the management toolset, we notice the following requirements: 1) it has to be a single  set of tools 2) simple enough to use and 3) it should work on both traditional IT and cloud.
 Some common functions from this management tools include governance, security, compliance, service assurance, patching, service lifecycle management etc. 
The toolset should be able to give a complete view of the IT infrastructure. Complete means the toolset includes automation, orchestration, security, performance management and financial management tools. In addition, the cloud management platform should be consistent in meeting business SLAs.  These SLAs are met by providing capabilities such as security with the support for automation, compliance and backup, role based access and identity management. Simple code analysis tools go a long way in assuring this. Further, Information correlation and application analysis and network level defense mechanism can thwart or preempt attacks. Some IT tools already work well in this space but the suggestion is to keep it open enough for any tool to provide the functionality or a platform tool that can integrate with others.
Performance monitoring tools is also part of this toolset. Advanced reporting and analytics tools that involve chargeback and license compliance to be reported also complete this toolset.

One more coding question for today :
A list of objects have colors red, white or blue. we need to sort them by the color red, white or blue.

public static SortedSet<Color> SortColor(List<Color> items)
{
// parameter validation
var set = new SortedSet<Color>(new ByColor());
foreach (var item in items)
{
set.Add(item);
}
return set;
}

public class ByColor : IComparer<Color>
{
public int Compare(Color x , Color y)
{
if (x.color == y.color) return 0;
if (x.color == red) return 2;
if (x.color == white)
{
 if (y.color == red) return -2;
else return 1;
}
//x.color  == blue;
if (y.color == red) return -2
else return -1;
}
}
