Public and private clouds offer users differing experiences and capabilities. With a private cloud, your network has its own dedicated cloud. Yet, with a public cloud, your network shares the cloud with many others.
This article compares private cloud vs. public cloud to help you decide which model best suits your needs.
Private Cloud: Advantages and Disadvantages
A private cloud is a cloud computing environment for one customer.
Private clouds are usually hosted on-premises in a customer’s data center, but they can also be hosted on a cloud provider’s server or a rented server offsite.
Advantages
The private cloud has several advantages:
| Control | With a private cloud environment, you are free to purchase the hardware and software that best suit your needs. You can also control delivery and ensure the maximum availability of cloud resources. |
|---|---|
| Customization | The private cloud allows you to customize servers and software as needed with add-ons and custom development. You can also customize your cloud environment for each department or end user. |
| Highly economic | With a private cloud, you receive greater security and access control than with a public cloud, as workloads typically run behind your firewall. If your organization has sensitive and confidential information, a private cloud ensures an extra layer of security. |
Disadvantages
There are also several disadvantages to private clouds:
| Cost | Private clouds have the disadvantage of being more expensive. Their cost includes buying, installing, and managing new hardware, software, and networks. Another significant bottom-line impact of private cloud deployments is training expenses. |
|---|---|
| Scalability | With a private cloud, scalability can also be an issue. You may need to buy more hardware and software to scale your private cloud. Additionally, the infrastructure might not have the scalability to meet unpredictable demands if it is limited to on-premises computing resources. |
| Maintenance | The setup and maintenance of private clouds are more expensive and time-consuming. |
Public Cloud: Advantages and Disadvantages
Most cloud computing deployments are public clouds. A third party owns and operates public cloud resources. They deliver these resources over the Internet. Cloud providers own and manage all hardware, software, and other infrastructure. You will also share these resources with other customers.
Advantages
Advantages of public clouds include:
| Cost | Using a public cloud means you don’t have to buy hardware or software. You only pay for what you use. Compared to private clouds, a public cloud saves you money upfront. Many plans include landline connectivity, so you only need to pay one bill. A single public cloud infrastructure serves multiple users, so vendors can charge less. |
|---|---|
| Scalability | With a public cloud, you can access as much storage and processing power as you require. As your needs change, you can add resources to the public cloud. This scalability allows for faster development and deployment of products and services. |
| Maintenance | Public cloud vendors handle and maintain shared computing resources amongst many tenants, so your maintenance costs stay low. Your IT team is therefore free to work on other core duties and responsibilities. |
Disadvantages
Disadvantages of public clouds include:
| Control | Using a public cloud means you don’t have to buy hardware or software. You only pay for what you use. Compared to private clouds, a public cloud saves you money upfront. Many plans include landline connectivity, so you only need to pay one bill. A single public cloud infrastructure serves multiple users, so vendors can charge less. |
|---|---|
| Customization | The public cloud is multi-tenant, which can limit customizations. Public cloud providers have a limited package of services from which you can choose. Though you can keep costs down, the provider hasn’t tailored these packages to your business needs and network architecture. |
| Security and Compliance | The public cloud isn’t the best choice for mission-critical IT workloads because it is less secure than a private cloud. When you work with a public cloud company, you allow them to manage and secure your data in a multi-tenant environment. Your company data may be at risk if an unauthorized outsider gets access. |
Synopsys and Cloud-based Chip Design
Synopsys has chip development and verification tools for any cloud option. Chip makers rely on us for on-premises electronic design automation (EDA) tools and semiconductor IP.
You can choose our software-as-a-service (SaaS) product or our bring-your-own-cloud (BYOC) option if you already have a trusted cloud provider.
We can help you deliver innovative products, whether you’re a chip designer or a software developer.
