The IT organization leverages the management tools used in their traditional data center processes to provide visibility into silos and control of the infrastructure. They also have adapted some ITSM concepts as a framework for their management practices.
During the initial phase of the service deployment, a problem was encountered in one of the VMs. The IT organization is concerned about the extensive amount of time and resources spent determining the cause of the issue.
As a consultant, what should you recommend to prevent these types of service issues?

A) Contract with an outside organization that has extensive experience in resolving cloud service issues
B) Upgrade the management tools to provide holistic visibility into the service dependencies

2. Refer to Scenario 1 below.
An IT department is offering 50 Service Offerings in their service catalog to meet all the application developers' needs. Many of the variants have a very small number of associated instantiations. A "big data" platform is offered and being actively utilized by a team of data scientists.
All services are sourced from within the private cloud. The developers are able to customize the platform's compute, storage, protection and network configuration upon instantiation. They can also provision additional resources after the initial instantiation through an upgrade service within the catalog. Because of the culture of the organization, no chargeback mechanism is implemented.
Within six months, IT experiences these problems:
