assets/processes; considers impact of harm/loss; identifies critical paths
and single points of failure (SPOFs); determines compliance costs
(legislative/contractual).
⩥ Metered service. Answer: Organization pays only for the resources it
uses.
⩥ Rapid elasticity. Answer: Excess capacity can be quickly apportioned
to cloud customers (scale up/down fast).
⩥ Cloud bursting. Answer: Use external hosted cloud to augment private
datacenter during demand spikes (crisis/holiday); rent extra capacity as
needed.
⩥ Cloud service benefits (general). Answer: Reduced personnel cost;
reduced capital expenditure; reduced operational costs; transfer some
regulatory costs; reduced archival/backup costs.
,⩥ ROI (Return on Investment). Answer: Profitability ratio; net profits
divided by net assets.
⩥ Elasticity (cloud). Answer: Virtualization-based flexible allocation of
needed resources; supports portability/accessibility/availability while
controlling costs.
⩥ Simplicity (cloud). Answer: User can use service seamlessly without
frequent interaction with provider.
⩥ Scalability (cloud). Answer: Increase or reduce services quickly and
cost-effectively.
⩥ IaaS (Infrastructure as a Service). Answer: Most basic model;
customer installs OS/software on provider hardware; can act as warm
site for BC/DR; least expensive; customer retains IT staffing.
⩥ IaaS—when to use. Answer: Website/app hosting; virtual data centers;
data analysis.
⩥ PaaS (Platform as a Service). Answer: IaaS + provider-managed OS
options; provider patches/admins OS; customer installs apps/software;
supports dev/testing; includes cloud DB engines and big data services.
,⩥ PaaS—when to use. Answer: Reduce development time; support
multiple programming languages; collaboration for distributed teams;
high dev capability without additional staff.
⩥ Unstructured data. Answer: Qualitative; natural-language text; media
(audio/video/images); JSON/XML/binary objects; important for
analytics; often NoSQL.
⩥ Structured data. Answer: Quantitative; organized for machine
processing/ML; SQL/relational; easy input/search/manipulation.
⩥ SaaS (Software as a Service). Answer: IaaS + PaaS + applications;
provider administers/patches/updates everything; customer mainly
uploads/processes data; app is shared responsibility.
⩥ SaaS—when to use (personal). Answer: Email (Gmail); cloud storage

, ⩥ Private cloud. Answer: Resources dedicated to one customer; may be
owned/operated by customer or hosted at provider; can be co-lo with
provider physical security/utilities/admin.
⩥ Community cloud. Answer: Owned/operated by/for an affinity group;
shared ownership; can be provisioned by third party; example:
FedRAMP services for US federal government.
⩥ Hybrid cloud. Answer: Combination of models; e.g., keep private
resources while leasing public cloud services for dev/testing (PaaS).
⩥ Cloud broker. Answer: Company that buys hosting services from a
provider and resells them to its own customers.
⩥ CASB (Cloud Access Security Broker). Answer: Third-party entity
offering independent IAM services (SSO, cert management, key escrow)
to CSPs and customers.
⩥ Regulators (cloud context). Answer: Ensure compliance with
regulatory frameworks (HIPAA, GLBA, PCI DSS, ISO, SOX, etc.);
include FTC, SEC, auditors.
⩥ Cost-benefit analysis. Answer: Compare potential positive impacts
