CIS-676 - Test 1
Homogeneous architecture
homogenous cloud is one where everything is from the same vendor
Business architecture relates to:
Business defines what the business requirements that are needed
CMMI
CMMI is geared specifically to software development organizations and focuses on continuous improvement
Hub Economy
Hub economy drives innovation and competition between Hub companies and creates new IT products and advances IT.
Heterogeneous architecture importance
(Data Privacy/ownership) choose a public cloud provider, like Azure, GCP, or AWS, and then pair it with a private offering like those from VMware, CloudStack, or OpenStack.
Business architecture
A blueprint of the enterprise that provides a common understanding of the organization and is used to align strategic objectives and tactical demands
Pioneer
A few more go/Learns from explorer - slightly defined route/Still big risks/Still potentially big benefits/A few more return but plenty do not/A few more realize big upside benefits/When successful, the prize is still pretty "rich"
Heterogeneous architecture
A heterogeneous cloud, on the other hand, integrates public and private components from more than one vendor
ITIL
Best practice framework for IT service management and operations including hardware life cycle (ITSM runs on ITIL)
Hosted private cloud
Cloud within the company / own the services
TCO concerns
Difficult to know where money is being spent
Enterprise architecture relates to:
Enterprise defines the platforms and standards to be used
Data
Facts that can be analyzed or used in an effort to gain knowledge or make decisions; information.
n-tier
Flexibility / Scalability / Reliability / Availability / Performance
technology characteristics that businesses seek to achieve in today's global economy
Globalization/Global Financial system/Protectionism/Labor/Inequality/Global Trade/Markets/Productivity & Efficiency/Automation/Economic Bads/Money/Competition/Capital/Quality of Life
follower
Go in mass/Few are hurt/Risk is greatly reduced/Most reach the destination/Big upside benefits were previously realized/Little downside risks
Composition of Technology Architecture
Infrastructure/Applications/Data/ - Services/Organization
ITSM
It basically pertains to the process involved in managing IT services like planning, operating, controlling and delivering
Settler
Learn even more from explorers and pioneers/Many try the journey/Most reach the destination/Lower downside risks/Lower high volume benefits/When successful, the price is rarely "winning the lottery"
Traditional data center without a cloud
Local or leased data center on primuses
Composition of Enterprise Architecture
Made up of Business architecture and Technology architecture
Process Immaturity
No objective basis for judging product quality or for solving product or process problems / Product quality is difficult to product
Process Maturity
Organization-wide ability for managing software development and maintenance processes
Butlers Axioms
Out of sight, out of mind/All technology grows and ages/The too few, to many concept
Private cloud on premises
Owner control / private and local (WAN)
Gartner
Research group
Composition of Business Architecture
Services/Processes/Information - Composed of architectures, processes, workflows and events
Explorer
Small numbers/Goes into unchartered waters/ Big risks - risky venture/Potential big returns/ many never return/many never realizes benefits/when successful, the prize is "rich"
CMMI
Specific to software development and continuous improvement
Technology architecture relates to:
Technology provides the methods to support the business and run on
ITSM
The IT services of a customer are managed here
Applications
The function- or process-specific computer programs the organization uses and also the process by which they are created, maintained and managed
Infrastructure
The number and types of computers the organization uses, the operating systems that runs on them and the communications networks that allow individuals and computers to talk to each other
TCO
Total Cost of Ownership
Public cloud
You don't own the hardware third party does / Less private / Shared Luns / Private space
Enterprise architecture
a well-defined practice for conducting enterprise analysis, design, planning, and implementation for the successful development and execution of strategy
ITIL
addresses IT operations issues such as security, change and configuration management, capacity planning, troubleshooting, and service desk functions.
TCO
an estimation of the expenses associated with purchasing, deploying, using and retiring a product or piece of equipment. TCO, or actual cost, quantifies the cost of the purchase across the product's entire lifecycle
CMMI
capability maturity model integration
Hub Economy
dictates where technology is headed. It drives the future state where we are at and where we are going.
Homogeneous architecture importance
everything comes pre-integrated they are easier to set up, and if something goes wrong there is only one responsible party
Hub firm / company
including Alibaba, Alphabet/Google, Amazon, Apple, Baidu, Facebook, Microsoft, and Tencent—occupy central positions
ITIL
information technology infrastructure library
ITSM
information technology service management
ITIL
is broader in scope and provides a framework for IT service management and operations including a hardware life cycle.
CMMI
is focused toward software development, maintenance, and product integration
CMMI
mainly focused on continuous and long-term improvement for business processes
ITSM
manage delivery of serveries better (ITIL needed to implement ITSM) - needs ITIL framework
Colocation
you own servers / third party manages machines for you ( You buy your own equipment and move it into a datacenter to be managed by a third party) (LAN / WAN)
