The software deployment models define how software is sent and operated for their users. Choosing the right model can affect everything from cost to performance:

• Enterprises must evaluate not just features but also how software is deployed.
• Deployment models influence scalability, maintenance, and overall user experience.

There are some common deployment models in both traditional and cloud systems. They come with their own pros and cons, such as:

• On-premises: the software is installed locally on their own servers or devices.
• Hosted: the software runs on external servers.
• SaaS (cloud-based): the software is supplied over the internet.
• Hybrid: it unites two methods (on-premise and hosted) for its flexibility.

Cloud computing has newer, faster, and easier deployment methods. These models often offer faster setup and lower costs:

• Cloud deployments are scalable and reduce the need for internal IT support.
• Hosted and cloud solutions usually have maintenance, security, and backups.

Software vendors may support more than one deployment model to serve their customer needs. The best choice depends on each technical, financial, and organizational factor:

• Large businesses may prefer hybrid for more control and flexibility.
• Small businesses might favor the cloud for their simplicity and affordability.

What is the cloud deployment model?

A cloud deployment model refers to how your cloud services are made to be available, where they host them, and who controls them. Choosing the right cloud computing deployment model could be dependent on the business needs and their resources.

Types of cloud deployment models

There are four main cloud deployment models:

1. Public 

In a public cloud deployment model, space resources like servers and storage are owned by a third-party provider. There are many companies that offer them, but these are the most known: AWS, Microsoft Azure, and Google Cloud. It’s cost-effective and highly scalable, but you share the space with other users.

2. Private 

A private cloud deployment model is where the cloud space is used exclusively by one organization. It can be hosted on-site or by a provider, offering this way greater control and security. This setup is ideal for sensitive data.

3. Hybrid 

This type of model combines both public and private models. It allows the data and apps to move between those systems, allowing businesses to have their flexibility while balancing privacy and scalability.

4. Community 

The community cloud deployment model is shared by many businesses with similar needs, like healthcare or education sectors, and they are often co-managed. This model is less commonly used. 

Why does the right cloud deployment model matter?

Choosing the right cloud development model can affect the cost, performance, and compliance. For example:

• Startups may prefer public cloud for affordability.
• Enterprises that have strict regulations, they often need a private or hybrid setup.
• Government or any other public institutions can also benefit from community cloud models.
