Introduction to
IT Infrastructure
IT Infrastructure
Architecture can be divided into four types - business architecture, the strategies of business operation, application architecture, which focuses on deployment and integration of software, enterprise architecture, which integrates various business segments, and this architecture, which involves the parsing of information.
What is Data Architecture?
IT professionals require continuous improvement skills, knowledge of AI, customer engagement, and this, which references their ability to adapt to problems and work within the ever-changing business landscape.
What is Flexibility?
The detailed service practices within IT comprise ITIL, which stands for this.
What is the Information Technology Infrastructure Library?
This is essential because of the expertise the field requires means customers cannot do it themselves.
What is IT Service Delivery?
Unlike this methodology from which DevOps borrows heavily, DevOps does not shun operations and instead integrates said team with the development and planning teams.
What is Agile?
Of the first four R's in the Seven R's of Change Management, Risks asks what risks are involved, Return asks what's required, Reason asks why the change is happening, and this asks who initiated said change.
What is "Raised"?
Agile's flexibility and focus on nonlinear project development has lead to the idea that it is the opposite of this methodology which is much less "free flowing" than its name would suggest.
What is Waterfall?
Solution Architects manufacture IT solutions. Enterprise Architects align IT infrastructure with business goals. This third type of architect, however, is an expert in one particular section of technology.
What is a Domain Architect?
Social Networking, Real-Time Analytics, and Mobility are all trends in IT, but none are quite as large as these main two, focusing on off-prem storage and parsing resources.
What are Cloud Storage and Cloud Computing?
Standards, which are sets of rules that define how computer components are made, are often one of four types; they can be Ad Hoc, formed by an interested party for a given device, Consensus, created by a cross section of stakeholders, De Facto, reached by the consumer standard for the product, or this, defined by the nation's governing body.
What is a Government Mandate?
The second through sixth steps of the ITIL Service Value Chain are Improve, Engage, Design & Transition, Obtain or Build, and Deliver & Support. However, it all starts with the first step of the ITIL Service Value Chain, this step which is identical to the start of the SDLC.
What is Planning?
When speaking about DevOps practicum, this word is often placed in front of words like "Improvement", "Delivery", and "Feedback" to emphasize the WIP nature of DevOps.
What is "Continuous"?
Of the three last R's in the Seven R's of Change Management, Resources asks what's required to deliver the change, Responsibility asks who does what, and this asks what the change will do to other changes.
What is "Relationship"?
The Four Tenants of Agile include Interaction Over Processes and Tools, Working Over Comprehensive Documentation, Responding to Change, and interaction with these end users.
Who are Customers?
End User Devices, the Operating Systems that run them, DBMS servers to populate the instance, and Storage such as on-prem options like SAN or cloud-based like AWS S3 are some of the components to use this cloud-based software company's resources.
What is Salesforce?
Daveed installs a program on his coworker's computer to fix a bug without approval, installing malware by mistake, an example of the dangers of this.
What is Shadow IT?
Whereas SOC 2&3 are more relevant to the IT side of things, setting standards for security and availability with and without sensitive information respectively, SOC 1 is mostly focused on this.
What is Financial Reporting / "The Business Side"?
The five components of ITIL are Guiding Principles, Governance, Service Value Chain, Practices, and this, which focuses on adapting to the ever-changing technology landscape.
What is Continual Improvement?
DEV, TEST, and PROD are all types of this, which are often seen in the DevOps cycle to ensure the quality of deliverables before release.
What are Environments?
These are one or agreed upon Configuration items which are formally approved and controlled.
What is a Baseline?
Scrum projects are broken into 2-4 week phases, known as these.
What are Sprints?
WAN Circuits, Routers, Switches, LAN, WiFi, and Firewalls are required components of this business resource required for SalesForce.
What is Networking?
Current IT issues include Cloud Computing, Virtualization, and these three issues, shortened to GRC.
What are Governance, Risk, and Compliance?
Data centers are certified by this, ensuring they have proper security and redundancies. If they pass inspection, they even get a certificate!
What is the Uptime Institute?
Disasters, events which threaten the existence of the organization, have a different recovery process than Incidents (Log, Categorize, Troubleshoot, Escalate). Problem Management, which often deals with these events, can be one of these two types, either foreseeing issues and preparing, or acting once a problem materializes.
What are Proactive and Reactive?
DevOps requires Standardization, Automation, Configuration, Cross-Training, and this, which ensures the software is up to date for all users and outdated ones are updated properly.
What is Version Control?
Standard Changes are small and usually given with minimal notice, like a day-of memo. Normal or Planned Changes are sizable, but give at least 24 hours notice, usually. These changes, however, cannot give notice yet have large consequences for an organization.
What are Emergency Changes?
In Kanban, projects in group N are worked on until group N+1 takes over said project, similar to a production line whose conveyor belts lend this production ideology its name.
What is Pull Production?
Being managed at all times, redundant power sources and cooling, security, and geographic separation for disaster recovery are the reasons these are often off-prem.
What are Data Centers?
Where once specialization was required, this trend in IT now requires expert generalists to do more with less and dissolve silos within the business.
What is IT Flattening?
ISO develops data center standards, including ISO 14001 & 50001 for environmentalism, 9001 for operations practices, and this ISO standard for security.
What is ISO 27001?
The Four-Dimensional Model of ITIL reflects these four dimensions, better known as the Four P's.
What are Organization and People (People), Information and Technology Products (Products), Partners and Suppliers (Partners), and Value Streams and Processes (Processes)?
New Releases, Minor or Major, are much larger and often comprised of a few of these, which themselves are comprised of smaller fixes known as Patches.
What is a Service Pack?
What are Auditing and Reviewing?
There are a few differences between Scrum and Kanban. Firstly, whereas Scrum limits the amount of this spent on a given project, Kanban limits how much of it is consumed in a given state. Secondly, whereas Scrum requires them, Kanban does not require these, also known as iterations. Thirdly, Kanban does not define these whereas Scrum has them, including Scrum Master and Team Member. Lastly, Kanban has an ongoing one of these. Scrum may as well, but it resets after each sprint.
What are Time, Time-Boxes, Member Roles, and Board?
