Every business will go to a stage where they have to decide which cloud model they want to use.
Your job as a business analyst is to review business needs and identify the right cloud models to meet those needs. I admit, the language and vocabulary that everyone uses when you first start looking at this area.
What you should know is that the debate between the public and the private cloud has been heated in the cloud technology sector for some time. We have no winners yet, and I’m not sure we’ll get any sooner.
So, let’s get into this …
This is the one you might be familiar with, if you use google docs, dropbox and slack you would use universal cloud.
Universal Clouds is owned and maintained by third party service providers, the most popular being; Amazon Web Services, Azure and Google Cloud Platform. Under this model, the business is able to upscale or downscale relatively quickly to adapt to its business model. All in all, under the public cloud users will share the same infrastructure with each other, they will feel the same security protection as each other.
A key difference between public and private cloud is that as a business you are not responsible for maintenance, bandwidth, applications and hardware. These costs are covered by the provider.
Which customers …
Customers who benefit from this service …
The application will be used by everyone in the organization, for example, google docs 7
না If it is not clear how many users will use the service
Users want to keep costs low
• The team must have access to collaborative projects that do not require strong security infrastructure
• Cost model: pay-as-you-go model using public cloud; Thus, users only have to pay for the resources they use.
Flexible approach: There is no agreement on how long a business should use the service
• Share hardware: Under the public cloud, users can purchase services, databases and hardware devices to run their business.
The big difference between private cloud and public cloud is that private clouds are created to meet business needs only. Owned by a private cloud company.
This cloud model enables businesses to be able to host applications in the cloud and at the same time meet any data and security concerns of users.
There are two different types of personal clouds-
On-premises private cloud:
This model is commonly referred to as the “inner cloud”. The cloud is hosted by the business’s own data center. It allows businesses to process standards and give users the protection they need. However, the size and scalability of this model is limited and therefore the user can limit what he can do with this cloud model.
This type of cloud is best suited to situations where users have applications that require control and configuration control over resource infrastructure and security.
Externally hosted private cloud:
This model is similar to the on-premise private cloud model, the only difference being that an external cloud provider will host the cloud. Cloud providers will assure that the environment will be private.
This type of cloud is best suited for organizations that do not want to use the public cloud, as they are concerned about the risk of sharing physical resources.
• Security: Private cloud gives businesses complete control over their network design, data storage to meet their security and data needs.
Customizable: Since there is only one organization, users can customize applications in the cloud to meet their needs.
Consent: Consent is easy under the personal cloud as a user.
They have full control over the application and they can choose how they want to meet their consent requirements
Cost: All software and infrastructure for a business has to be purchased and maintained by itself, which can increase costs.
So, if you are part of a team that has to make a decision between the public and the private cloud – use this blog to frame the questions you need to ask the business.
