So many Cloud models to choose from

With several cloud models to choose from, it could be confusing to an organization. It is thus important to determine the different cloud computing models to be able to determine the one that best fits the particular requirements.

With many different cloud computing models and definitions, how could one know which is the best for a business? It is important to determine each cloud aspect as well as know the different cloud models.

Today, cloud computing is more than just another buzzword. That is why it is important to determine which cloud service is right for a business. The growing popularity of cloud computing has been impressive over the last couple of years. A lot of organizations have signed up to the idea of third parties to take care of workloads, providing them more time to innovate and focus on business operations that need the most attention. The cloud is a cost-effective method, which pays dividends in the long run, and thus it comes as no surprise that it has become a phenomenon.

Infrastructure as a Service (IaaS)

The most fundamental kind of cloud computing. If various complex, custom apps are run in-house, they could lend themselves to an IaaS cloud service. This avoids the cost in hardware that the apps run on, replacing with a pay-by-use model wherein the resources needed are rented without upfront costs or residual costs if use is stopped.

Platform as a Service (PaaS)

It is deploying apps on an external cluster of app servers, instead of the ones operated in-house. PaaS platforms are much less commonplace since providers often could not provide customers the diversity and control that they need for their apps. Moreover, vendor lock-in is another concern. As soon as an app starts to use any proprietary interfaces or tools that a PaaS provider makes available, migrating to another provider will become very hard. PaaS platforms typically are used for new projects, in which organizations are confident in the longevity of their chosen provider.

Software as a Service (SaaS)

SaaS replaces in-house apps with external app accessed through the web and often is the most straightforward option. The major differences are in the cost of using the app as well as the mode of use. SaaS apps typically are accessed remotely with a web browser, thus are more accessible but may not work as well as apps for certain tasks. The whole coding and infrastructure platform is thoroughly abstracted, enabling efficient software updates as well as continuous enhancement to the user interface.

1. The Public Cloud. The deployment model shows true cloud hosting. In this model, infrastructure and services are offered to various customers. Google is a great example of a public cloud. The service could be provided by a vendor for free or a license policy that’s pay-per-user model. The public cloud is a better choice for business requirements that required load management, host app that is SaaS based and manage applications that a lot of consumers use. Because of the lesser capital and operational costs, this model is cost-effective.

2. The Private Cloud. The model does not contribute much when it comes to cost effectiveness. It is as capable as being compared to purchasing, building and handling infrastructure. Still, it comes with great value from a safety viewpoint. During the initial cloud adaptation, a lot of concerns face challenges and have systems that are related to data security. The model provides the security concerns proper care. The infrastructure needed for hosting could be on premises or some other location. Safety issues are referred via secure-access VPN or through the physical location within the firewall system of the client. Furthermore, for critical apps, it requires downtime on internet availability, quality, as well as performance. Hosting an app with on-premises private cloud is the approach that is advisable.

3. The Hybrid Cloud. The deployment model helps businesses take benefits of secure and safe applications as well as hosting on private cloud, while still enjoying the reduction cost by keeping shared data and applications on the standard public cloud. Also, this model is used to manage cloud bursting, which implies to an environment which the present private cloud systems is not able to manage load spikes and requires a fallback option for load support. Thus, the cloud shifts workloads between public and private hosting with no problems or difficulties for users. Companies could use the high cloud model mixture to process big data. On a private cloud, it could preserver sales, business and different data could begin analytical queries over a public cloud since it is capable of meeting demand spikes. The model is designed with features such as scalability, security and flexibility.

4. The Community Cloud. A community cloud is identical to public cloud only because its access is limited to a certain community of cloud customers. Community clouds could be owned together by members of the community or by another party provider, which offers a public cloud with limited access. The member customer of the community primarily shares the responsibility of detailing as well as evolving the model.

4. The Hosted Cloud. The hosted private cloud is a model which a service provider could offer up a private cloud architecture in a remote data center, that’s completely dedicated to the customer. An organization benefits from not having to spend time to design the architecture or write automation software. Furthermore, it is able to convert all expenses from up-front capital to consistent operational cost.
