Cloud Computing Concepts

Traditional procurement methods involve upfront capacity purchases.
Cloud computing offers flexible, on-demand services.
Companies can adapt to fluctuations in usage without incurring unnecessary costs during off-peak periods.

What is Cloud Computing?

Computing power, databases, storage, networking and software can be delivered on demand.
Services utilize the internet.
Users can pay as they go
Requires no up-front infrastructure investment; resources are available as needed

NIST Cloud Computing Model

The NIST cloud computing model displays four essential characteristics:
- On-demand self-service
- Broad network access
- Resource pooling
- Rapid elasticity
- Measured service

Essential Cloud Characteristics

Components that make up cloud computing including:
- On-demand self-service
- Rapid elasticity
- Broad network access
- Resource pooling
- Measured service

On-Demand Self-Service

Services are accessible on demand and without human interaction with a service provider.
Users themselves can provision resources such as servers, storage, or web applications as required.
Organizations can manage resources using internal IT staff without reliance on the service provider's staff.

Broad Network Access

Accessing cloud-based resources from various networks is possible.
These networks can include internal local area networks, internet connections, or a combination of both.
Cloud-based resources can often be accessed globally.

Resource Pooling

Cloud service providers pool network, storage, and compute capabilities.
These pooled resources are allocated to customers on demand.
Economy of scale principles are applied.

Rapid Elasticity

Cloud-based resources can be scaled up or down to meet changing needs.
There is no need to perpetually maintain hardware resources that might be underutilized or idle.

Measured Service

The use of resources within the cloud is carefully tracked and measured by the service providers.
Billing is tied to actual usage of cloud resources.

Cloud Service Models

This section details the different types of service models for cloud computing:
- SaaS (Software as a Service)
- PaaS (Platform as a Service)
- IaaS (Infrastructure as a Service)

Infrastructure as a Service (IaaS)

All computing resources are provided in a virtual environment.
The cloud service provider remains responsible for supporting hardware.
Customers are responsible for managing virtual machines that run on the CSP's infrastructure.
Businesses can scale resource utilization as needed.
Reduced capital expenditures are a potential advantage versus traditional infrastructure purchases.

Platform as a Service (PaaS)

Cloud service providers maintain the operating system and hardware infrastructure.
It is a program language execution environment enabling developers to build, compile and run programs.
Users can typically use the platform for developing and running applications, or database services.
Focus is on providing an appropriate environment to facilitate application development.

Software as a Service (SaaS)

Software is delivered on-demand over a network without installation efforts.
The cloud service provider takes responsibility for the underlying infrastructure--patches, hardware, operating system etc.
Software is typically licensed via subscriptions.
This model is highly adaptable to various hardware or operating system configurations.
It is specifically geared for end users
