According to the research conducted by various institutions, it has been revealed that cloud computing has plenty of advantages. From the data released by a survey, 80% of the IT executives say that the metrics which are in connection to the cloud will grow in the years to come. The real deal is that what type of cloud service model would be better for you. Regardless of the benefits of cloud server models, it has been proven that cloud servers are quite beneficial for organizations and there are many factors which you have to focus upon while you decide which model suits best for your business.
There are 3 kinds of cloud service models in cloud computing solutions. Each of them has similarities but each of them is distinct in its own way. The cloud service models are Software-as-a-Service, Infrastructure-as-a-Service and Platform-as-a-Service. Each of them has been explained below:
Infrastructure-as-a-Service is the first layer and the base of cloud computing. By utilizing this service model, you are able to manage the data, application, OS, runtime and middleware. The basic responsibility of the service provider is that it manages the data storage, networking, servers and virtualization. This will help you overcome the expenditure which would come over the human capital and hardware. This aids in the reduction of the ROI risk and smoothens and automate scaling. Some of the biggest names in IaaS are Microsoft, VMWare, Amazon, Red Hat and Rackspace.
If by some means the basic need of this model is for the client who requires extra data space for the processing of power, the service will prove to be quite flexible. It allows you to scale on the basis of your needs and you only have to pay for the resources which are utilized. This would create extra data processing space and you can use it whenever you need it. If you do not require such a service, you will not pay for it. This would save you money and provide you the best services required by your business.
The Platform-as-a-Service model is considered to be the second layer of cloud computing. You can easily manage the data and the applications and the rest of it is managed by the cloud vendor. The advantages of using PaaS include the smoothening of deployment version and the ability to change, upgrade and minimize the expenses. The best PaaS is the Google app engine.
If we talk about a business which possess limited resources and is interested in application testing and development then the best service for this kind of business is Platform-as-a-service. The benefits that you will enjoy in this case are minimized expenses and overhead costs regarding the hardware.
Software-as-a-Service is the final and last layer of the cloud service model. This layer helps the business run programs over to the cloud where all of the sections are being managed by the cloud vendor. The user assures that the same software is compatible and easy to collaborate. In this way, the company will not have to pay any extra taxes for the licensing fee and you can easily add more users. This would streamline your applications programs. The best example of this platform is Hotmail and Gmail. If you have a team, which is easy to manage and that is responsible enough to maintain the hardware for your business, SaaS would suit your requirements well. For a large scale organization, this is the best scenario. By using this platform, your team would be able to access the software over a variety of services and it would allow easier collaboration as well.
