Hi Guys! Happy to see you around. Thank you for clicking this read. In this post today, I’ll walk you through Types of Cloud Computing.
Cloud computing is not a new term. Companies have been using this infrastructure for the past two decades. You might be familiar with this term, in case you don’t, cloud computing is the on-demand availability of computing resources over the internet. Simply put, you can process, store and manage a large amount of data using this architecture. The companies offering these services to end-users are called Cloud Service Providers (CSP). And most of these services offer the pay-as-you-go model which means you can ask for only those computing resources required for your business; you don’t pay for the resources you don’t use in the cloud computing model. This liberates you from using on-site data centers for managing data, and you get computing resources online including storage, processing power, and databases.
I suggest you read this post all the way through as I’ll thoroughly cover the Types of Cloud Computing and how they can be used for improving the activities of any business.
Types of Cloud Computing
Earlier on-site data centers were a norm for the management of large amounts of data, but cloud computing has gained momentum due to its ability to effectively manage and store the onslaught of data online. Moreover, since these resources are available online, you don’t need hectic IT drills to install, manage, scale or update traditional data centers. These data centers over the cloud are globally managed to give you access from anywhere in the world.
The following are the main types of cloud computing.
1: Public Cloud
2: Private Cloud
3: Hybrid Cloud
4: Community Cloud
No two clouds are the same and picking the cloud type is dependent on the business needs and requirements. Every cloud enables computing power over the network and allows the running of workloads within that system. These cloud models differ in terms of storage capacity, location, and accessibility but they all work on the same principle of virtualization. There is a lot of confusion in each type and I’ll try my best to remove these confusions so you can better understand what each type is all about. We’ll discuss them one by one in the section below.
1: Public Cloud
Public clouds are typically created for businesses but they are not owned by the individual business. Public cloud providers manage and run these clouds and offer services to organizations based on their current needs and requirements. The common public cloud providers include:
- Amazon Web Services
- IBM Cloud
- Google Cloud
- Microsoft Azure
- Alibaba Cloud
This is the most cost-effective option for organizations that don’t have enough capital to invest in the development of IT infrastructure. Public cloud resources are shared by a variety of end-users which means this model is not made for a specific business. Instead, computing resources are shared among businesses of all sizes.
Although this is the preferably best option for businesses to handle a large amount of data, this model doesn’t guarantee the security of sensitive data since this architecture is shared by multiple organizations.
Moreover, this infrastructure offers less customization options and the service providers hold the main authority. A single tweak from the provider’s side can drastically impact your business. For improved security and better control over data, a private cloud is used.
2: Private Cloud
In a private cloud, computing resources are owned by a single organization. This model offers two options: resources can be hosted on-site IT infrastructure or businesses can hire a third party to host their computing resources.
Compared to the public cloud, this model is a bit expensive since it gives you more customization power with improved security. Companies dealing with sensitive data can pick this model since here resources are not shared by a variety of businesses.
Private cloud, if hosted on on-site data centers, gives you the power to fully control the computing resources and make the adjustment based on your internal processes and preferences. Even though this model gives you more control, you require professional IT experts to handle and manage the private cloud on-site. If you don’t want to involve yourself in the nitty-gritty of handling complex IT infrastructure required for private cloud, you can get services from a third party to host and manage your resources on their system. This way you still own the private cloud but you require less technical expertise for handling this model.
Better security is another advantage that comes with a private cloud. Companies require a large amount of data to be handled and stored and in the public cloud that data is vulnerable to cyber-attacks since the computing resources are shared by multiple end-users. To prevent your sensitive data from being compromised or deleted, it is better to keep this type of data within your private security boundary so no one can manipulate your data for their advantage.
3: Hybrid Cloud
Hybrid cloud combines both private cloud and public cloud. You can share data and applications between two clouds using this cloud deployment model. This way workload is not handled by a single cloud architecture, instead, it is shared by two different cloud models.
For instance, organizations need unlimited storage capacity to store a large amount of data, public cloud comes in handy for this purpose for handling non-sensitive data. While, on the other hand, if companies want the processing of sensitive data on the premises of their business, the private cloud is the solution.
Hybrid models are common since they set you free from the long-term investment on a specific cloud model, instead, you can use the combination of both models and ask for required computing resources valuable for your business.
4: Community Cloud
Community cloud is valuable for those sharing common business goals. A variety of businesses use cloud computing models including healthcare, education, manufacturing industries, IT sector, and more. Community cloud is suitable for companies falling under the same business model. For instance, organizations falling under the education sector can pick for community cloud with similar computing resources and storage power. Cost is another factor behind the popularity of this model. The resources cost is split between the organizations picking this cloud model.
Uncommon Cloud Types
If you’re still reading this post, it means you have got a clear idea about the four main types of cloud models. However, there are also less common cloud types used for specific purposes. These types include:
Don’t get confused. This is different from hybrid cloud. In a hybrid infrastructure, companies can get computing resources from both the private and public cloud. While Multicloud is not the combination of different clouds, instead it’s the provision of computing resources from two different cloud service providers. For instance, you can ask for public cloud resources from two different providers to avoid dependency on one single provider.
B: Distributed Cloud
At its core, a distributed cloud is an architecture that runs from multiple locations but is not owned by a single organization. This model is used to meet the company’s specific performance and compliance needs and it does support edge computing but essentially is managed and controlled by the public cloud provider.
C: HPC Cloud
This model is particularly developed to support high-performance computing applications. This model is useful if you want to perform research on a large scale and are looking for a solution for advanced computing problems.
Every business is unique.
It’s your job to carefully monitor the activities of your business and put dedicated thought to pick the particular cloud computing model for your business.
How you want your data to be managed, processed, and stored does matter. If you want to handle a large amount of data, the public cloud is a valuable solution. And if you want the sensitive data to be processed locally, the private cloud is the answer.
And the best part?
You can deploy both private and public cloud models to selectively handle sensitive and non-sensitive data.
And if you don’t want to remain dependent on a single service provider, you can leverage the services of two providers and use them to your advantage.
Make sure you consider the proper security protocols before picking up the right architecture. A single mistake in the initial steps of choosing the cloud model can drastically impact your business in the long run. So be careful.
