what are the application requirements? - answer Capacity, availability, and performance
(CAP)
why do we prioritize workloads? - answer you want to make sure the more important
things are working properly so everything else can work as well
What is an application? - answer programs that complete a task, automate a process,
allows employees to work, external or internal facing, and revenue generating
capacity - answer how much information the business process generates over time how
much it needs to be kept for a certain time, capacity storage

Enterprise resource planning (ERP) - answer much broader scope than resource
management including manufacturing, SCM, financials, projects, HR, CRM, and data
warehouse
What are the 3 workload requirements? - answer capacity, availability, and performance
,application - answer live on hardware, interface of data
"middleware" - answer application and database interact
database - answerback end of application, we do not see this
operating system - answerlives on the hardware
hardware - answerinfrastructure, servers, storage, any hardware has an operating
system to make it efficient
concurrency - answerconcurrent access (meaning at the same time) to the same
database by multiple users
security - answersecurity rules determine access rights of users
integrity - answerdatabase structure and rules improve the integrity of the data
data descriptions - answera data dictionary provides a description of the data
front end application - answergenerate the data, generate the workload
databases - answerback end apps manage the data, organize, index, modify, and
access the data
storage - answerstoring and protecting data, data is accessible to the end user through
applications
what is a workload? - answerthe total requests made by a user and application of a
system
what is a "business server" - answera collection of related workloads which allow end
users to complete a specific set of business tasks
how are workloads generated? - answeremployees enter info into a predefined
application screen
what is a "field"? - answereach space that data can be entered into a database behind
the app and not directly accessible by the user
what is a data "write" or "input? - answernew data that is being saved or existing data
that is being changed
what is a data "read" or "output"? - answerexisting data that is being reviewed
, what is an IOP? - answerinput/output per second, measures of storage system
workloads
unstructured (file) data - answermost difficult and expensive to protect, highest amount
of data redundancy, word, power point
structured (block) data - answereasiest to protect, moderate amount of data
redundancy, database data, phone #s
what are the two types of data? - answerunstructured (file) and structured (block)
active content - answerinfo in the process of being created or is regularly updated,
currently relevant to the business, recent emails, stock prices
static content - answerhas not been changed or accessed over a long period of time,

CPU (central processing unit) - answerbrains of the computer, conducts communication
between components of the server, "core" = 1 CPU
RAM (random access memory) - answervolatile memory where working data is stored,
more RAM generally provides better performance
HDD/SSD (hard disk drive/solid state drive) - answerstorage for all the data, transfers
only block data
NIC (network interface card) - answercontrols for external devices such as keyboards,
mouse, and storage devices
clients - answerprocessing power designed to fit the needs of one user
server (run applications) - answermore powerful, more storage, more CPU, more NICs,
more OS functions, better security
tower - answerlooks like a desktop, takes up more space than blades or racks, support
closet deployment, could be noisy
