Cloud computing architecture refers to the components and subcomponents required for cloud computing. These components typically consist of a front end platform, back end platforms, a cloud based delivery, and a network. Combined, these components make up cloud computing architecture.
Client platforms
Cloud computing architectures consist of front-end platforms called clients or cloud clients. These clients are servers, fat clients, thin clients, zero clients, tablets and mobile devices that users directly interact with. These client platforms interact with the cloud data storage via an application, via a web browser, or through a virtual session. Virtual sessions in particular require secure encryption algorithm frame working which spans the entire interface.
Zero client
The zero or ultra-thin client initializes the network to gather required configuration files that then tell it where its OS binaries are stored. The entire zero client device runs via the network. This creates a single point of failure, in that, if the network goes down, the device is rendered useless.
Storage
An online network storage where data is stored and accessible to multiple clients. Cloud storage is generally deployed in the following configurations: public cloud, private cloud, community cloud, or some combination of the three also known as hybrid cloud. In order to be effective, the cloud storage needs to be agile, flexible, scalable, multi-tenancy, and secure.
The software-as-a-service service-model involves the cloud provider installing and maintaining software in the cloud and users running the software from cloud over the Internet. The users' client machines require no installation of any application-specific software since cloud applications run in the cloud. SaaS is scalable, and system administrators may load the applications on several servers. In the past, each customer would purchase and load their own copy of the application to each of their own servers, but with the SaaS the customer can access the application without installing the software locally. SaaS typically involves a monthly or annual fee. Software as a service provides the equivalent of installed applications in the traditional delivery of applications. Software as a service has four common approaches:
single instance
multi-instance
multi-tenant
flex tenancy
Of these, flex tenancy is considered the most user adaptive SaaS paradigm in designated multi-input four way manifold models. Such systems are based on simplified encryption methods that target listed data sequences over multiple passes. The simplicity of this concept makes flex tenancy SaaS popular among those without informatics processing experience, such as basic maintenance and custodial staff in franchise businesses.
Development as a service (DaaS)
Development as a service is web based, community shared tool set. This is the equivalent to locally installed development tools in the traditional delivery of development tools.
is web based design construct where cloud data is accessed through a defined API layer. DaaS services are often considered as a specialized subset of a Software as a Service offering.
is cloud computing service which provides the users with application platforms and databases as a service. This is equivalent to middleware in the traditional delivery of application platforms and databases.
is taking the physical hardware and going completely virtual. This is the equivalent to infrastructure and hardware in the traditional method running in the cloud. In other words, businesses pay a fee 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.
