Question 1

In Apptio, what is a Unit?

Answer 1

Unit
In the Apptio applications, a unit is a value in an identifier column. For example, if the identifier for an object in a model is Products, the units would be the product names in the Products column. The object’s unit table contains one row for each unit, with each row in the unit table containing the sum of all of rows for each unit in the source data set.

Question 2

What is a Unit Driver?

Answer 2

Unit Driver
In an Apptio model, a unit driver is a calculated data value, typically determined by a formula, that determines the value of an object. A unit driver pulls data set information into an object. A change in the value of the unit driver changes the value shown in the object, which propagates throughout the model based on the relationships that have been defined between the objects.

Question 3

What is a Unit Table?

Answer 3

Unit Table
In the Apptio applications, a unit table is a table that represents the data associated with an object. A unit table contains references to one or more data sets.

Question 4

What is Unused Storage?

Answer 4

Unused Storage
Allocated storage not yet written to.

Question 5

What is Usable Storage?

Answer 5

Usable Storage
Capacity of a frame that can be allocated to filesystems. aka “Total Capacity Apptio reports on the storage elements of interest: all components of Usable Storage.

See: Available and Allocated Storage.

Question 6

What is Value?

Answer 6

Value
The ITIL Service Strategy book describes utility and warranty as forming the basis of value for IT service consumers. Simply put, according to ITIL, get utility and warranty right, and you are providing the intended value, which means you have a high quality service with satisfied customers.

UTILITY: The ITIL glossary adds that utility is “[f]functionality offered by a product or service to meet a particular need. Utility is often summarized as ‘what it does’.”

WARRANTY: ITIL describes warranty as “ promise or guarantee that a product or service will meet its agreed requirements” and as “derived from the positive effect of being available when needed, in sufficient capacity, and dependably in terms of continuity and security.”

Customer Measures of Value:
* Functionality
* Ease of Use
* Performance - supports my needs
* Reliability- is it available when needed
* Agility - how fast to fulfil
Price - competitive with alternative

Question 7

What are Variable Costs?

Answer 7

Variable Costs
Costs that change in proportion to the activity of the business.

Question 8

What is Vertica?

Answer 8

Vertica
3rd party software made by HP. The grid-based, column-oriented, Vertica Analytic database is designed to manage large, fast-growing volumes of data and provide very fast query performance when used for data warehouses and other query-intensive applications. Its design features include:

* Column-oriented storage organization, which increases performance of sequential record access at the expense of common transactional operations such as single record retrieval, updates, and deletes.
* Out-of-place updates and hybrid storage organization, which increase the performance of queries, insertions, and loads, but at the expense of updates and deletes.
* Compression, which reduces storage costs and I/O bandwidth. High compression is possible because columns of homogeneous data types are stored together and because updates to the main store are batched. Shared nothing architecture, which reduces system contention for shared resources and allows gradual degradation of performance in the face of hardware failure

Question 9

In Apptio, what is View Only?

Answer 9

View Only
In the Apptio TBM Suite, View Only is the second lowest level of role. Users with the View Only role can see all projects and all shared and role reports. They can drill down on reports and edit tables on viewable reports. They can also view models and the inference map.

Question 10

What is a Virtual Instance?

Answer 10

Virtual Instance
An operating system image that is hosted on a hypervisor (or multiple clustered hypervisors). The virtual instance runs one or more IT or business applications or services.

Question 11

Describe the 3 Virtualization Options?

Answer 11

Virtualization Options
Physical – A standalone physical server running a single operating system image. The physical server typically runs one or more IT or business applications or services. It is not hosting other operating system images or otherwise acting as a hypervisor.

Virtual – An operating system image that is hosted on a hypervisor (or multiple clustered hypervisors). The virtual instance runs one or more IT or business applications or services.

Private cloud – A dedicated, elastic, scalable virtualized environment available to internal users (as opposed to public cloud). The private cloud provides virtual instances that run one or more IT or business applications or services. This is differentiated from the “Virtual” servers by the automated provisioning and related capabilities.

Question 12

What is Whitespace Storage?

Answer 12

Whitespace Storage
Raw storage associated with frame overhead; cannot be allocated to a server/file system.

Whitespace is always incorporated into sunk Storage costs. It gets allocated per the strategy governing Usable Storage.

Question 13

What does YTD stand for?

Answer 13

YTD (Year to Date)
Year-to-Date. The cumulative value from the beginning of the fiscal year to the current date.
