Cloud computing is normally defined in one of two ways, based on the deployment model, or on the service that the cloud is giving. Primarily, programs that are needed to run a particular application are presently more popularly placed on a remote device or machine, owned by another company. This is done with a view as to not to lose on the quality performance which may be due to the processing power of your own computer, to save money on IT assistance, and still, remain beneficial on the market. These machines or networks that run the applications, preserve and store the information, and manage a server system through cloud consulting services, are basically what we call “the cloud”.
Based on a deployment model, we can distinguish the cloud as
When we speak about the public cloud, we imply that the whole cloud computing service or infrastructure is located on the premises of a cloud consulting company that gives cloud assistance. So the location of the server here remains separate from the customer and he has no physical access over the infrastructure. As public clouds use shared devices, they do excel chiefly in performance but are also prone to or may mostly get exposed to various attacks.
Private Cloud renders the same advantages of Public Cloud but utilizes dedicated private hardware. A private cloud involves using a cloud network entirely by one customer or organization. It is not shared with others, though it is remotely positioned. The companies have an alternative of choosing an on-premise individual cloud as well, which is more costly, but they do have physical control over the system. The security and authority level is highest when using a private network. But, the cost reduction can be minimal, if the company would like to spend in an on-premise cloud infrastructure.
Hybrid cloud means using both private and public clouds, basically a combination of both, depending on their purpose. For instance, the public cloud can be utilized to interact with clients and for keeping their data secured within a private cloud. Most businesses link traditional public cloud service with flexible scalability and the capacity to handle continuous shifts in demand. Though, performance issues can occur for some data-intensive or high-availability workloads.
Community Cloud implies an infrastructure that is shared among organizations, normally with the shared data and data management concerns. For instance, a community cloud can refer to the government of a single country. Community clouds can be positioned both on and off the premises.
Based on a service the cloud model is giving, we are addressing either:
IaaS is the lowest level of cloud solution and refers to cloud-based computing infrastructure provided by a Cloud Strategy and Consulting Services company as a fully outsourced service. An IaaS provider will give pre-installed and configured hardware or software by a virtualized interface. What the clients accessing the cloud services do with the service is up to them. For instance, managed hosting and development environments. A web hosting company is an IaaS provider. Some of the larger players offering infrastructure as a service solution include Google, IBM, Rackspace Cloud Servers, and Verizon.
Benefits of IaaS Solutions
- Reduces total cost of ownership and capital expenditures
- Companies pay for the service that they want, on the go
- Access to enterprise-grade IT resources and infrastructure
- Clients can scale up and down based on their requirements at any time
This kind of cloud computing is related to IaaS although is further advanced. With PaaS, apart from just providing infrastructure, providers also offer a computing platform and solution stack as a service. The IT infrastructure will come with a graphic user interface, run-time system libraries, programming languages or an operating system. PaaS services are often used by companies that require to develop, test, collaborate and deploy cloud solutions for particular applications. Here, the hosting of the application is done by a third company i.e. the PaaS provider. PaaS providers advise a fully configured sandbox and deployment environment for clients to develop, test and deploy their cloud applications. PaaS solutions examples are Salesforce.com’s Force.com, Rackspace Cloud Sites, Google App Engine and Microsoft Azure.
Generally, Cloud Consulting Services is thought by people as Software as a Service (SaaS) providers. SaaS providers implement fully functionally web-based applications on demand to clients. The applications are largely targeted at business users and can involve web conferencing, ERP, CRM, email, time management, project tracking among others.
The payment models for SaaS solutions may involve subscription-based (Salesforce), pay-for-use (WebEx) or free. Examples of Cloud Consulting Service companies that offer SaaS solutions are Citrix, NetSuite, and others.
Benefits of SaaS Solutions
- Agile Scalability
- Conveniently access from any place with Internet
- Reduces infrastructure concerns
- Customized service offerings
- Bundled maintenance and Assistance
