A

Algorithmic IT Operations

51
Q

What is AIops?

A

assumed to mean artificial intelligence for IT operations

52
Q

what is a benefit of AI ops?

A
  • instead of siloed teams monitoring their own parts, all important monitoring data is collected in one place
  • machine learning used to identify patterns and detect abnormalities
  • issue detection and prediction
  • proactive system maintenenace and tuning
  • threshold analysis - enabling more accurate picture of the normal range of operation of a system
53
Q

AI ops allows IT operations to

A

Identify and resolve high-severity incidents faster
detect potential problems
automate routine tasks and focus on strategic work

54
Q

AIOps can do what?

A

harness data platforms and machine learning
collect observational data and engagement data
draws insight by applying cognitive or algorithmic processing to it.

55
Q

This is an applied form of artificial intelligence, based on the principle of systems responding to data, and adapting their actions and outputs as they are continually exposed to more of it

A

Machine learning

56
Q

Types of machine learning

A

Supervised - a supervisor determines the learning algorithm and the sample data set used to train the machine. The inputs and expected outputs are defined.
Unsupervised - the machine learns from the input data alone

57
Q

Benefits of Machine learning

A
  • ability to derive valuable results from quantities of data which would be difficult for humans to process
  • enables improvements in the efficiency or accuracy of decision making
  • enables the automation of entirely new data driven decisions
58
Q

Limitations of machine learning

A

performance of the system is depend on its data, the algorithms used, and the quality of training for supervised systems
- results can be distorted if the input data contains inherent bias

59
Q

What is deep learning?

A

a subset of machine learning based on artificial neural networks, it relies on computing systems modeled on the biological neural networks found in animal brains

60
Q

What is CI

A

Continuous integration - an approach to integrating, building, and testing code within the software development environment

(Checked in code is validated, through a set of automated tests, then merged into a shared code branch for deployment to production)

61
Q

What is Continuous Delivery?

A

Continuous delivery - an approach that focuses on ensuring that software can be released to prod at any time

frequent deployments are possible, but deployment decisions are taken case by case, due to a preference for a slower rate of deployment

62
Q

What is Continuous deployment?

A

an approach in which changes go through the pipeline and are automatically put into the prod environment, enabling multiple prod deployments a day

63
Q

Details on CD/CI

A
  • it is a methodology for delivering software in an agile manner
  • commonly known as the opposite of a more linear waterfall approach (waterfall defines the process as linear series of phases)
  • sometimes confused with DevOps, but devops contains more context on team orgs and culture in addition to system delivery
64
Q

CI/CD goals & measurements

A
  • Smaller, high frequency deployments of changes to systems
  • reduced risk, making each deployment less complex
  • increased velocity of value co-creating, by enabling useful changes to be delivered more quickly to consumers.

small changes are easier to comprehend, consume, test, troubleshoot and roll back

65
Q

CI/CD teams focs on

A
  • Identification and removal of bottlenecks that reduce the speed of delivery
  • automating delivery that require manual effort
  • ensuring each change maintains quality
  • automating validation and testing of each change
66
Q

True or false

a significant focus for organizations using CI/CD is the reduction of toil (work requiring manual effort)

A

true

67
Q

This is a set of tools, integrations, practices, and guardrails that allow a continuous and substantially automated flow of changes, from their initial design and development through to deployment into production

A

CI/CD pipeline

68
Q

The three stages of work flowing through a CI/CD pipeline

A
  • Build automation (the CI phase) - includes version control to merge multiple dev changes into one branch
  • Test automation - each change is tested and validated as part of the flow chain from dev
  • deployment automation - the automation of the actual process of moving code from pre prod to prod
69
Q

ITIL guiding principles

A 
Focus on value
start where you are
progress iteratively with feedback
collaboration and promote visibility
think and work holistically
keep it simple and practical
optimize and automate
70
Q

Agile approaches are good for which situations?

A
  • there is uncertainty about present and future requirements
  • risks associated with errors or failure are low impact or managed quickly
  • iterative nature enables the ongoing development to understand customer demands and respond to them
