Cloud computing is a kind of distributed computing, refers to the network “cloud” will be huge data processing procedures broken down into countless small procedures, and then, through the system composed of multiple servers to process and analyze these small procedures to get the results and return to the user. In the early days of cloud computing, it was simply distributed computing that solved the problem of task distribution and consolidation of results. Thus, cloud computing is also known as grid computing. With this technology, the processing of tens of thousands of data can be done in a very short period, resulting in powerful web services. At this stage what is called cloud services is no longer just distributed computing, but a result of the evolution and leap forward of a mixture of computer technologies such as distributed computing, utility computing, load balancing, parallel computing, network storage, hot backup redundancy, and virtualization.
Cloud computing refers to the formation of computer networks through the computational power of the system, can be stored, the collection of related resources, and can be configured on demand, to provide personalized services to users.
Cloud computing (Cloud computing) is a new type of computing model based on the Internet, which provides on-demand, scalable, reliable, flexible and secure computing resources and services through the network. Cloud computing is the product of the integration of traditional computer and network technologies such as distributed computing, parallel computing, utility computing, network storage, virtualization, and load balancing.
Key features of cloud computing include scalability, reliability, and flexibility. Scalability means that cloud computing can automatically expand and shrink computing resources and services according to user needs, with high elasticity. Reliability refers to the high availability and fault tolerance of computing resources and services provided by cloud computing to ensure service continuity and stability. The flexibility is reflected in the fact that cloud computing can provide a variety of computing resources and services, including computing, storage, network, application, etc., to meet different user needs.
In NIST 800 145, it is mentioned that there are five basic characteristics of cloud computing. They are:
1. cloud computing must have on-demand self-service
2. extensive network access
3. Pooling of resources
4. Fast elasticity
5.Measured services
Meanwhile, there are three main types of cloud services such as Software as a Service (SaaS), Infrastructure as a Service (LAAS) and Platform as a Service (PAAS). Each different type of cloud service has different limitations in terms of managing its applications, operating systems or databases.
NIST specifies five characteristics of cloud computing, including self-service, complete network support, resource pooling, fast scaling, and measurability. Cloud computing has many advantages such as flexibility, scalability, high reliability and low cost. With cloud computing, users can easily scale up or down computing resources to meet changing business needs. At the same time, the total cost of ownership for users can be reduced because the equipment and resources in the data center can be fully utilized.
As cloud computing became more popular, NIST determined what it meant and created a simple taxonomy. Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources. It has five basic characteristics: on-demand self-service, extensive network access, resource pooling, fast resiliency, and metered service. It has three different service models: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). It also has four deployment modes: private cloud, community cloud, public cloud, and hybrid cloud. These classifications provide clear guidance for system planners, project managers, technical experts, and others adopting cloud computing in their systems.
As cloud computing becomes more popular, NIST has identified its meaning and created a simple taxonomy. Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources. It has five essential characteristics: on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. It has three different service models: software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS). It also has four types of deployment models: private cloud, community cloud, public cloud, and hybrid cloud. Those classifications provide clear guidance to the system planners, program manager, technologist, and others who adopt cloud computing in their system.
While cloud computing provides many benefits, at the same time, it also introduces various risk that need to be governed and managed by user organizations. This is a highly detailed document provides notes and baseline to any individual who is considering cloud computing. The document has provided a formal definition and five characteristics of cloud computing. It also offers three service models and four deployment models that could be used in any particular business operation.
NIST SP 800-145 serves as a foundational resource for organizations seeking to understand the fundamental concepts, characteristics, and deployment models of cloud computing and provides guidance for effectively leveraging cloud technologies to meet their business objectives.
The measured service provided by cloud computing is an essential feature that automatically controls and optimizes resource utilization by employing metering capabilities at an appropriate level of abstraction, such as storage, processing, bandwidth, and active user accounts. Resource usage can be monitored, controlled, and reported, ensuring transparency for both the provider and consumer of the utilized service. And this measured service enables cloud computing systems to accurately track and manage resource usage, thereby improving resource utilization efficiency and cost control capabilities. For service providers, it helps them better understand resource utilization, optimize resource allocation, and enhance service performance and reliability. For service consumers, it provides greater transparency and visibility, allowing them to better understand the services they are using and adjust and optimize them according to their actual needs.
NIST defines cloud computing as a model that enables ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources. It outlines five key characteristics of cloud computing: self-service, complete network support, resource pooling, fast scaling, and measurability. These characteristics make cloud computing an attractive option for organizations seeking flexibility, scalability, high reliability, and cost-efficiency. With cloud computing, businesses can effortlessly scale up or down their computing resources to align with changing business needs, leading to reduced total cost of ownership as equipment and resources in the data center are fully utilized.
To further categorize cloud computing, NIST introduces three distinct service models: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Additionally, there are four deployment modes: private cloud, community cloud, public cloud, and hybrid cloud. These classifications provide clear guidance for system planners, project managers, technical experts, and other stakeholders as they adopt cloud computing within their organizations. The taxonomy created by NIST helps stakeholders understand the nuances of cloud computing and make informed decisions when implementing it within their systems.
Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and distributed with minimal administrative effort or service provider interaction. Cloud computing is ubiquitous in our lives, with broad network access. Functionality is available over the network and accessed through standard mechanisms that facilitate the use of heterogeneous thin or fat client platforms (e.g., phones, tablets, laptops, and workstations). The cloud can be used to store files. The advantage is that backups are simple. They automatically synchronize files from the desktop. Dropbox allows users to access files and store up to 1 TB of free storage space. Social networking platforms require robust hosting to manage and store data in real-time. Cloud-based communication provides click-to-call functionality from social networking sites and access to instant messaging systems.
NIST Special Publication 800-145 defines cloud computing as a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This definition emphasizes the key characteristics of cloud computing, including on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. One of the most notable aspects of this definition is its emphasis on the user-centric nature of cloud computing, highlighting the convenience and accessibility that cloud services provide to users. Additionally, the definition underscores the importance of shared resources and automation in delivering cloud services, highlighting the efficiency and scalability benefits that cloud computing offers. Overall, NIST’s definition provides a comprehensive and concise overview of the fundamental concepts and principles that define cloud computing as a paradigm shift in the delivery of computing services.
This reading has given me a deeper understanding of the service and deployment models of cloud computing. One notable feature is the relatively limited control consumers have over the underlying cloud computing infrastructure. They are typically limited to basic setup and configuration, such as selecting the approximate geographic location of a service (e.g., country or state), without precise control over its physical location.
Because of this limitation in control, resource management becomes particularly critical. By properly managing resources, consumers can work to minimize potential risks. Therefore, I believe that consumers should consider deploying a private cloud when conditions allow. This way, they can have more control over all the underlying infrastructure and resources.
In addition, hybrid cloud is an option worth considering. With a hybrid cloud, consumers can keep sensitive resources on a private cloud while deploying other resources on a public or community cloud that best suits the organization. This flexibility not only provides better resource management options, but also allows consumers to adjust cloud configurations as needed. In this way, they can take full advantage of the benefits and conveniences of cloud computing while ensuring that critical resources are secure and controlled.
Based on the reading, what I find interesting is that cloud computing has three types of services, IaaS, SaaS, and PaaS.The organization can use different types of services based on their needs. I think is very important for the organization to be familiar with different types of cloud services. That will make the organization choose the right services for the data and information, help organization save their data in a suitable place.
Cloud computing is a computing method that refers to the network “cloud” to decompose a large number of data calculation and processing programs into countless small programs, and then processed and analyzed through a system composed of multiple servers. The applet gets the result and returns it to the user. The cloud model consists of five basic characteristics: on-demand self-service, extensive network access, resource pooling, fast resilience, and measurable service. According to NIST, there are three service models: Software as a service, infrastructure as a service, and platform as a service. And four deployment models, private and community. Public cloud and hybrid cloud.
Cloud computing is a pay-as-you-go model that provides available, convenient, on-demand network access to a configurable shared pool of computing resources (including networks, servers, storage, applications, services) that can be made available quickly with minimal administrative effort or interaction with service providers.
Cloud computing has five basic characteristics: on-demand self-service, extensive network access, resource pooling, rapid resiliency, and service metering. There are three service models for cloud computing, including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). In addition, there are four deployment models for cloud computing: private cloud, community cloud, public cloud, and hybrid cloud.
NIST categorizes the characteristics of cloud computing into five key features:
1. On demand self-service: Users can independently obtain and configure computing resources as needed, without the need for manual intervention or advance booking.
2. Broad network access: Cloud computing resources can be widely accessed through standard network connections (such as the Internet), and users can use cloud services through various devices (such as computers, mobile phones, tablets).
3. Resource pooling: Cloud computing providers gather computing resources from multiple users to achieve resource sharing and efficient utilization. Users don’t need to worry about the specific location of resources, they just need to know they are available for use.
4. Rapid elasticity: Cloud computing resources can be quickly expanded or reduced according to needs to adapt to changing user needs. Users can increase or decrease computing power, storage space, and other resources as needed.
5. Measurable service: Cloud computing providers can monitor, control, and report on resource usage to provide users with transparent billing and resource management.
In addition, NIST provides four deployment models for cloud computing:
1. Public cloud: Cloud services are provided to the public through a public network by third-party providers, and users can purchase and use them on demand.
2. Private cloud: Cloud services are provided internally by a single organization or entity, based on a private network or data center, and are only open to specific users or organizations.
3. Community cloud: Cloud services are jointly used and managed by multiple organizations or entities to meet the needs of specific communities.
4. Hybrid cloud: Cloud services are composed of multiple cloud environments (such as public and private clouds), allowing data and applications to migrate and interact between different cloud environments.
Cloud computing services has become a valuable asset in delivering IT resources and has become an on-demand service with essential characteristics, service and deployment models. With these features being the core to cloud computing, this allows users to access technology services, and take advantage of computing and storing data. In Measured Service, being one of the essential characteristics to cloud computing, the cloud provider measures how much service the customer uses (whether it be storage, processing, or user accounts that are active) and then they are billed based on a pay or charge-per-use basis.
Cloud computing is a model used to achieve efficient, convenient, and on-demand access to pre configured computing resources (networks/servers/storage/applications/services). These computing resources can be quickly obtained and released, while management costs are extremely low, and communication costs with providers are basically zero. NIST has also identified five characteristics of cloud computing, three service modes, and four deployment modes.
NIST SP800-145 provides basic resources for organizations seeking to understand the basic concepts, characteristics, and deployment models of cloud computing, as well as provides support for guiding enterprises to efficiently use cloud technology to achieve business goals. There are three types of cloud computing services, IaaS, SaaS, and PaaS.Organizations can use different types of services depending on their needs.

The four deployment models include public cloud, private cloud, community cloud and hybrid cloud.
I thought this was a really clear, straightforward high-level explanation of the key characteristics of the cloud, and then different models that a cloud service or deployment can take. In my experience, particularly for those outside of the IT field, the cloud can be a confusing concept. I thought this very clearly explained common elements of the cloud and then differences among different modes (for example Saas vs, PaaS vs. Iaas). I definitely plan to use this as a reference in the future to serve as a resource for people who may not be familiar with the cloud and what the basic terminology means.
