Managed Cloud Service Provider and Its Characteristics
A cloud provider is a firm that proposes some component of cloud computing such as Platform as a service (PaaS) or Software as a service (Saas), Infrastructure as a service (IaaS) to various other individuals or service. These cloud providers are often know as cloud service providers or CSP’s. Whenever cloud providers are evaluated, there are various things to ponder upon. There are a number of variations to be considered though most of the time the cost is based on per use utility model. Moreover, for sensitive data, the physical location is also a factor that should be considered.
To access any data, reliability is a must. A regular cloud storage agreement clearly mentions the levels of service e.g. 99.9% uptime. It is crucial to comprehend the fine print in that agreement state outages lower than 10 minutes that is very long for few businesses.
Another important consideration is security. In order to be in compliance with the criteria’s various companies provide certification to cloud service providers. Many cloud trusted programs were formulated to enable cloud service providers create access and compliance management methods, industry recommended and secure practices.
The features of cloud computing is shared with the following:
- Utility Computing
- Client Server Model
- Fog Computing
- Peer to Peer
- Grid Computing
- Dew Computing
- Mainframe Computer
CHARACTERISTICS OF CLOUD COMPUTING
- Agility enhances with the ability of the end user replan sources related to technological infrastructure.
- Cost reductions that cloud users claim. A basic delivery model used in cloud computing converts capital expenditure into operational expenditure. Now, as the infrastructure is given by a third party and is not purchased for detailed computing tasks, it lowers the barriers to entry.
- Device and location independence helps the users to use systems with the help of a browser irrespective of their location and devices they are using such as mobile phone, pc or laptop.
- Maintenance of such computingis simpler because they do not need their locations and are not required to be installed on each and every computer.
- Multitenancy helps many users to share resources and cost amongst them. Moreover, it also helps in utilization and efficiency, centralization and peak load capacity.
- Scalability and elasticity provisions resources on a self service basis.
- The five essential characteristics of cloud computing are also rapid elasticity, on demand self service, measured service, broad network access and resource pooling.
SERVICE MODEL OF CLOUD COMPUTING
Below, we have presented a typical service model of a cloud computing program. It includes Infrastructure of s service (IaaS), Platform of a service (PaaS) and Software of a service (SaaS). It shows how these three are intertwined with the cloud clients to form a complete network. In the model below, the cloud user preserves and patches the application software and operating systems. On a utility computing requirements, cloud users bill IaaS services and the amount of resources consumed and allocated is reflected in the cost.
