Cloud Computing Types and Their Differences: A Must Read Before You Make a Decision
Earlier, people used to run programs or applications from the software which had to be downloaded from a server or a physical computer. Cloud computing services have brought a tremendous change by providing them access to those applications through the medium of the internet. As per International Data Group, 69% of businesses are already using cloud technology in one capacity or another, and 18% say they plan to implement cloud-computing solutions at some point.
For companies extending their infrastructure or planning for digital transformation, cloud computing solutions have become the ideal way. To be precise, it delivers computing services like servers, storage, and the Internet. Also, the companies that offer these services are called cloud computing service providers. Most of us use an online service to send emails, edit documents, watch movies, etc, and probably you are using one of the cloud services right now also. Cloud computing solutions make all our online actions possible. Its cloud symbol, as per its definition, represents a set of varied devices that are networked together.
Cloud computing solutions were first implemented in the ’90s, but its practice as an Elastic cloud started in 2006. Now we can proudly call it the new common. With the growing digitization, it is always difficult for an individual to keep all their vital information stored on-in house computer servers, and here cloud computing comes as a savior. Many apps are using it as a default option, say for example Gmail services or the cloud back-up of photos in the smartphone, even AWS services are high in demand. Cloud computing runs on a simple principle where users have all the access of files without having a bulk on the system. Gmail, Google Drive, TurboTax, Facebook, and Instagram are examples of cloud-based applications.
Types of Cloud Computing
Each cloud has different features and you need to choose the right one as per the need. Cloud computing solutions are categorized into two categories:
Based on Hosting
- Public Cloud
- Private Cloud
- Hybrid Cloud
- Community Cloud
Based on Services
- Infrastructure-as-a-Service (IaaS)
- Platform-as-a-Service (PaaS)
- Software-as-a-Service (SaaS)
Let's know about them in detail:
Based on Hosting
This environment can be used by the general public includes individuals, corporations, and other types of organizations. Typically, public clouds are administrated by third parties or vendors over the internet, and services reoffered on a pay-per-use basis. It consists of users from all over the world wherein a user can simply purchase resources on an hourly basis and work with such resources which are available in cloud provider’s premises. These types of cloud computing solutions are quite popular among start-ups or companies with lesser capital.
This cloud computing environment resides within the boundaries of an organization and is used exclusively for the organization’s benefits. It can either be private to org. and managed by a single organization or can be managed by a third party. As it is deployed and managed by the organization itself, hence there are very few chances of data being leaked. Data is usually stored in the same geographical location where cloud users are present. You can hire a proficient software development company, which can create a cloud computing solution per your needs.
It is a cloud infrastructure that is provisioned for exclusive use by a special community of consumers from organizations that have shared concerns. It may be owned, merged, and operated by one or more organizations in the community, a third party, or a combination of them, and it may exist on or off-premises. In this, a private cloud is shared between shared organizations.
Based on Services
Infrastructure-as-a-service (IaaS) solutions are the most basic category of cloud computing services that lets you lease the whole infrastructure on rent from a cloud provider.
Platform as a service (PaaS)
PaaS services are quite popular among entrepreneurs who are looking to create applications promptly. Here business owners do not have to worry about the whole infrastructure of servers and networks, required for development. It, in a way, offers an on-demand environment for developing, testing, delivering, and managing software applications.
Software as a service (SaaS)
It is a way where app development companies create apps over the internet on a subscription basis. It allows you to host and manage your app quite smoothly from upgrades to maintenance, you do not have to worry about anything.
Now, let us discuss the major differences between these four types of cloud computing basis on safety, costing, SLA’s, etc.
Public Cloud: Cloud is offered to the public on a pay-as-you-go-as-you-need basis, hence the user has to pay only for what he is using which does not involve any cost of deployment.
Private Cloud: As compared to a public cloud, it is a bit expensive. Budget is a constraint here as it is managed by a single organization or by a third party.
Hybrid Cloud: Hybrid cloud has the benefit of being cost-effective as organizations pay for the public cloud portion of their infrastructure only when it is needed. Though, the initial deploying cost of a hybrid cloud exceeds as compared to the setup cost incurred in case of a public cloud.
Community Cloud: As a complete cloud is shared by several organizations or communities, hence it becomes cost-effective.
Public Cloud: Since it is offered by a third party and they have full control over the cloud, it is less secure.
Private Cloud: As it is deployed and managed by the organization itself, hence there is the least chance of data being leaked.
Hybrid Cloud: Private cloud is secured and the public cloud has a risk of the security breach. Hybrid Cloud cannot be fully termed as secure but as partially secure.
Community Cloud: Few organizations share the cloud, so there is a possibility that data can be leaked from one organization to another, though it is safe from the external world.
Public Cloud: Resources in the public cloud are large in number and service providers make sure that all requests are granted.
Private Cloud: SLAs play a very important role in any cloud service deployment model as they are defined as agreements between the user and service provider. In the private cloud, either Formal SLAs do not exist or are weak as it is between organizations and users of the same organization.
Hybrid Cloud: SLAs are stricter than private clouds and might be as per public cloud services.
Community Cloud: Community Cloud providers typically provide packaged service offerings with predetermined SLAs.
Public Cloud: Security assurance and thereby building trust among clients is difficult. Privacy and organizational autonomy are not possible.
Private Cloud: Organizations may have to invest in buying, building, and managing clouds independently. Budget and SLAs are a constraint.
Hybrid Cloud: Security features are not as good as private cloud and complex to manage.
As we move ever further into the digital age, it's becoming clearer that the adage “knowledge is power” has taken on the more modern and accurate form: “Data is money.” The adoption of cloud computing is increasing every year. By adopting cloud computing services, an enterprise can maximize the return on the investment. It is indispensable at all levels in our “online lives”. If you are a Startup or SME, along with saving your time and money, it helps you to face the competitions from counterparts or large enterprises.
Experts believe that cloud computing solutions will continue to benefit the mid-sized and large companies in the coming few years. With these benefits, it is just even more evident that the future of cloud computing holds great potential. It may open a wide range of opportunities for new employment, platforms, and much more in the future, so you must not waste any time and hire dedicated development team, to get a customized cloud computing solution developed as per your requirement.
