CloudChain, a cloud-oriented blockchain system is designed to increase the layers of security. [36] Currently, global spending on cloud computing services has reached $706 billion and the International Data Corporation predicts it to reach $1.3 trillion by 2025. [37]
Cloud bursting is an application deployment model in which an application runs in a private cloud or data center and "bursts" to a public cloud when the demand for computing capacity increases. A primary advantage of cloud bursting and a hybrid cloud model is that an organization pays for extra compute resources only when they are needed. [ 68 ]
Infrastructure as a service (IaaS) is the most basic form of cloud computing, where infrastructure resources—such as physical computers—are not owned by the user but instead leased from a cloud provider. As a result, infrastructure resources can be increased rapidly, instead of waiting weeks for computers to ship and set up.
The dynamic adaptation of capacity, e.g., by altering the use of computing resources, to meet a varying workload is called "elastic computing". [ 3 ] [ 4 ] In the world of distributed systems , there are several definitions according to the authors, some considering the concepts of scalability a sub-part of elasticity, others as being distinct.
This is the equivalent to infrastructure and hardware in the traditional (non-cloud computing) method running in the cloud. In other words, businesses pay a fee (monthly or annually) to run virtual servers, networks, storage from the cloud. This will mitigate the need for a data center, heating, cooling, and maintaining hardware at the local level.

According to The NIST Definition of Cloud Computing, [3] there are three service models associated with cloud computing: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). The concept of ITaaS as an operating model is not limited to or dependent on cloud computing.
The cloud-dew architecture was proposed as a possible solution to the offline data accessibility problem. [5] At first, its scope included only web applications; broader applications were later proposed. [6] [7] Dew computing is a model which was derived from the original concept of cloud computing.
