Cloud computing
Cloud Properties
-
-
Resource pooling : Multi-tenancy, shared infrastructure, location independence.
Rapid elasticity : Fast scaling up/down, perceived unlimited resources
Measured service : Metered usage, transparent reporting, pay-as-you-go.
Cloud Actors
-
Cloud Provider → The entity responsible for making a cloud service available (SaaS, PaaS, IaaS).
Cloud Auditor → An independent party that assesses cloud services in terms of security, performance, and compliance.
Cloud Broker → An intermediary that manages usage, delivery, and relationships between providers and consumers.

Cloud Deploiement models
Private Cloud → Cloud infrastructure for exclusive use by a single organization. Managed internally or by a third party, on- or off-premises.
Community Cloud → Cloud shared by several organizations with common interests (mission, security, compliance).
Public Cloud → Cloud infrastructure open to the public, owned and managed by providers
Hybrid Cloud → A composition of two or more distinct clouds (private, community, or public) bound together for portability and interoperability
Cloud Resources
Physical Resource Layer : Hardware & facilities (servers, storage, networks, datacenters, power, cooling).
Resource Abstraction & Control Layer : Virtualization & middleware (hypervisors, VMs, virtual storage, orchestration, monitoring, metering).
Service Layer : User-facing services (SaaS, PaaS, IaaS) accessed via APIs or portals.
Cloud Services models
Software as a Service (SaaS) → Consumers use applications hosted on cloud infrastructure without managing the underlying systems.
Platform as a Service (PaaS) → Consumers deploy their own applications using provider-supported tools and platforms
Infrastructure as a Service (IaaS) → Consumers provision fundamental computing resources (VMs, storage, networks) and manage operating systems and applications.
