Many organizations have already adopted the cloud, and those that haven’t taken the idea of cloud computing seriously are developing plans to move to the cloud. However, the main question which keeps on repeating itself here is what type of cloud is appropriate for what type of businesses.
Cloud computing is a type of computing that depends on resource sharing, rather than using local servers or individual devices to host applications. Cloud computing mostly only allows the application software to function when internet enabled devices are used.
Cloud computing usually serves a broad range of functions over the internet like virtual and storage servers; applications and authorization for desktop applications. It mostly capitalizes on resource sharing, and this allows it to be consistent and achieve economies of scale.
This article will, therefore, discuss the four types of cloud computing. These are:
Here, cloud services are offered over a network which is open for public usage. Public cloud is an accurate representation of cloud hosting, where the service provider delivers services and infrastructure to different clients. The customers on the other hand don’t have any control over the location of the servers. When compared to private clouds, there is a slight difference in their structural design.
Public cloud is best for businesses which have requirements that require managing the load; host application that is, Software-as-a-Service and manage applications which are used by many users. Public cloud computing is very economical because it has few capital overheads and operational costs.
Service providers have the option to provide the service for free or inform of license policy like pay-per-use. The costs of public cloud are shared by all users, so public cloud benefits the customers more by achieving economies of scale. Some public cloud facilities can be availed for free.
This is also known as the internal cloud. In private cloud, cloud computing services are offered on a cloud-based secure environment. The environment is usually protected by a firewall which governed by IT department which belongs to a particular organization. In private cloud, the user is given a greater and direct control of the data.
It’s hard to define what makes a private cloud because it is usually determined by the services which can vary very significantly. Whether physical computers are hosted externally or internally, they can offer resources from a separate pool of the private cloud services.
Private cloud is best suited for businesses with compelling or unforeseen needs, uptime requirements, management demands and mission critical assignments.
Hybrid cloud integrates both private and public clouds. It has two or more cloud servers, which can either be public, private of community cloud servers. These are usually integrated together, but still, they remain separate entities.
Hybrid clouds cannot be just categorized into public, private or hybrid cloud because they can overcome the provider’s boundaries. Here, resources are provided by either external or internal providers. This is usually an adaptation among two platforms, where the exchanges are done between public and private cloud based on demand and pay-per-the-need.
Organizations can decide to use public clouds to house non-critical resources like development and test workloads. A private cloud can be used to house critical or sensitive workloads. Hybrid cloud is well known for its scalability, security, and flexibility.
In community cloud, cloud resources are mutually shared between many organizations which belong to a particular community, for example, banks and trading firms. This setup is typically shared amongst several organizations belonging to a certain group, which has the same computing apprehensions.
The community members typically share the same security, performance and privacy concerns. The main objective for these communities is to achieve their business related goals. Community clouds can either be managed internally or by third-party provider.
It can also be hosted internally or externally. A community cloud is usually suitable for organizations which work as joint ventures and require a centralized cloud computing ability to implement similar projects.
