Cloud service or pilvipalvelu which is sometimes referred to as cloud computing is whereby very many computers are connected in a network (internet) and communication among the computers/machines is real time. In some cases it refers to a resource that is provided and utilized through the internet. This is made possible through specific softwares tailored for this activity for example SaaS and IaaS platforms among others. In any of these platforms, the software is responsible in the distribution of the service to the users. For a cloud service to run there has to be a server hardware (virtual server) which is operated by specific softwares such as the ones mentioned above. The virtual servers are not static hence can be moved from one place to another hence convenient to users.
Characteristics of Cloud Service
Elasticity; cloud service or pilvipalvelu is elastic which implies that the resource allocation can be decreased or increased depending on demand. Due to its elasticity, the cloud can be decreased if the demand is lower and be increased if the demand increases which is commonly known as scalability. The cloud can be changed depending on the need. Another common characteristic of cloud service is its standardized interfaces (APIs). The interface helps in communication between two or more data sources. Cloud service enables a client to access cloud service more easily as compared to others. Other characteristics include self monitoring whereby one is able to monitor how he utilizes the cloud. Monitoring will help reduce the total cost of money that the clients use hence value for money. Finally cloud service is reliable as it improves when other multiple users are redundant thus the most preferred when it comes to businesses.
