- SOA (Service Oriented Architecture)

SOA Architecture – SOA is built on computer engineering approaches that offer an architectural advancement towards enterprise system. It describes a standard method for requesting services from distributed components and after that the results or outcome is managed. The primary focus of this service oriented approach is on the characteristics of service interface and predictable service behavior. Web Services means a set or combination of industry standards collectively labeled as one. SOA provides a translation and management layer within the cloud architecture that removes the barrier for cloud clients obtaining desired services. Multiple networking and messaging protocols can be written using SOA's client and components and can be used to communicate with each other. 

SOA provides access to reusable Web services over a TCP/IP network, which makes this an important topic to cloud computing going forward. This element of cloud technology allows organizations to access cloud based computing solutions with features that can be modified on demand, as business needs change. Service Oriented Architecture allows independent web services to communicate with each other via the Internet in real time, providing the flexibility that is required to rapidly reconfigure the service delivery for a specific cloud computing offering. SOA places the responsibility and costs of development, deployment and maintenance of web service components on the web services provider, which allows a web services consumer to access various web services without the expense or overhead that is associated with traditional methods of IT services delivery. SOA is a powerful technological component of cloud computing because it facilitates centralized distribution and component reuse, which significantly drives down the cost of software development and delivery.

- Cloud Virtualization

Cloud Virtualization is another important aspect of a cloud system that facilitates the efficient delivery of cloud computing services. The implementation of virtual computing resources in the cloud, that mimic the functionality of physical computing resources, serves as a flexible load balancing management tool that allows for the swift adjustment of computing services delivery on demand. Virtualization technology provides organizations with a tool that promotes high levels of availability, scalability and reliability; in terms of the cloud systems or cloud computing technology that an enterprise can access to meet its information technology needs. Virtualization is also a very important component of cloud computing technology for the purposes of disaster recovery and fail-over support. 

Virtualization in Cloud Computing is making a virtual platform of server operating system and storage devices. This will help the user by providing multiple machines at the same time it also allows sharing a single physical instance of resource or an application to multiple users. Cloud Virtualizations also manage the workload by transforming traditional computing and make it more scalable, economical and efficient. Virtualizations in Cloud Computing rapidly integrating the fundamental way of computing. One of the important features of virtualization is that it allows sharing of applications to multiple customers and companies. Cloud Computing can also be known as services and application delivered to help the virtualized environment. This environment can be either public or private. With the help of virtualization, the customer can maximize the resources and reduces the physical system which is in need.
