2 . Cloud Computing Architectures 2.1 Cloud Software-as-a-Service: The software as service architecture gives access to a software infrastructure, which is remotely accessed via the web, based services. In this infrastructure, it is important to note that the service provider is responsible for managing the infrastructure. This architecture allows companies to get the business functionality of software by incurring a minimal cost, which is less than paying for the licensed applications. It follows the pay as you go, model. Software-as-a-Service eliminates all possibilities for organizations to handle the installation, set-up, daily preservation and maintenance. 2.2 Cloud platform as a service: This is also commonly known as the Paas†¦show more content†¦This cloud architecture allows the cloud provider to create a computing platform that consist of components such as hardware, servers, routers, storage, and other networking modules. The model follows the pay as you model where each user takes the services offered and pays for what they use or consume. Users can deploy and run any software, which comprise Operation Systems, applications. The cloud provider is responsible for managing the core cloud infrastructure for which users deployed applications or operating environment. Examples of this cloud computing model include Amazon Elastic Compute Cloud (Amazon EC2) which is an Iaas model that facilitates scalable compute volume, on-demand, in the cloud. It actually allows users make use of a plethora of Amazon s infrastructure with no up-front investments. Amazon EC2 decreases the clock needed to get hold of and boot latest server ins tances and permit users to immediately scale space – equally up and down as their computing needs vary. 3. Limitation of Cloud Computing 3.1 Data Management The shift of computer processing, storage, and software delivery away from the desktop and local servers, across the Internet, and into next- generation data centers results in limitations as well as new opportunities regarding data management. Data is replicated across large geographic distances, where its availability and durability are paramount for cloud service providers. It s also stored at untrusted
