There is no one-size-fits-all approach to cloud computing. To meet the rapidly evolving technology needs of enterprises, a variety of cloud computing models, formats, and services have emerged.
Cloud services can be deployed in one of two ways: public cloud or private cloud. The deployment system you use is determined by your company’s requirements.
What’s Better for Your Company: Private or Public Cloud?
If you want to migrate to the cloud, the first step is to figure out which cloud is best for you. You must consider this carefully because a hasty decision will result in wasted money, missed deadlines, project delays, disputes between you and your supplier, and a slew of other issues that can harm your company.
Difference Between Private Cloud and Public Cloud
Computing resources are shared among many customers in a public cloud (IaaS). In a private cloud, a single user has access to all computing resources, resulting in a physically and software-isolated environment.
Consider it this way: a public cloud is similar to renting a flat, while a private cloud is comparable to renting a house of equivalent size. The house is more private, but it also tends to be more expensive to rent, and it isn’t the most resource-efficient choice.
Both public and private clouds have pros and cons that you can weigh based on your company’s business objectives, IT growth plan, and financial condition. In this post, we’ll share how to choose the right cloud model for your business.
What is a Private Cloud?
This refers to cloud computing services that are only used by one company or organisation. It is typically physically stored on-site at your company’s data centre or hosted by a third-party. However, in a private cloud, the services and resources are still kept on a private network, and the software and hardware are applied only to your business.
A private cloud can make it more manageable for a business to tailor its services to meet specific IT needs. Government agencies, financial institutions, and other mid- to large-size organisations with mission-critical operations that want more control over their environment often use private clouds.
Many businesses prefer private cloud to public cloud because it is a more convenient – oronly way – to meet regulatory enforcement requirements. Others opt for private cloud because their workloads include confidential documents such as personally identifiable information (PII), medical records, intellectual property, financial details, or other sensitive information.
Advantages of Private Cloud
- Companies that use a private cloud have the option of purchasing their own hardware and software rather than the hardware and software provided by the cloud provider.
- Customers that use the private cloud may configure their servers in any way they like, and they can customize software as required through add-ons or custom creation.
- Since all workloads run behind the customer’s own firewall, there is more insight into security and access control.
- Customers who use a private cloud are not obligated to rely on the cloud service provider’s business and regulatory enforcement.
Drawbacks of Private Cloud
- The cost of a private cloud is higher, as it includes the cost of buying and installing new hardware and software, as well as the cost of operating it, which could require the hiring of additional IT workers.
- The versatility of a private cloud is somewhat constrained. Adding new features to a private cloud requires additional purchases after a company has invested in hardware and software.
What is a Public Cloud?
Public clouds are the most common form of cloud computing implementation. The cloud services such as storage and servers that are distributed over the internet are operated and owned by a third-party cloud service provider. The cloud provider owns and maintains all software, hardware, and other supporting services in a public cloud.
In a public cloud, you and other entities or cloud “tenants” share the same storage, hardware and network equipment, and you use a web browser to access resources and control your account. Web-based email, online office software, storage, and research and development environments are all popular uses for public cloud deployments.
Advantages of Public Cloud
- Without buying and installing new hardware, a customer may increase capacity in response to unspent traffic spikes in the public cloud.
- The majority of consumers will start using public cloud services without having to invest in their own physical computing infrastructure.
- Pricing options based on various SLA offerings are flexible.
Drawbacks of Public Cloud
- When used on a large scale, the total cost of ownership (TCO) can skyrocket, particularly for midsize to large businesses.
- Since public clouds are inherently insecure, they aren’t the right choice for sensitive mission-critical IT workloads.
