Understanding Cloud Deployment Models vs. Service Models

We need to break down some technical parts of cloud platforms. This knowledge will help you understand the different types of cloud computing. It involves highlighting the difference between a deployment model and a service model.

What Are Cloud Deployment Models?

Cloud deployment models define the location of the cloud infrastructure. They also determine who has control over it. In essence, they determine your computing resources’ physical and logical location.

The main deployment models include:

• Public clouds
• Private clouds
• Hybrid clouds
• Multi-cloud model

Each model offers different approaches to hosting. They also allow you to manage your applications and data with different methods.

Whatever method of cloud deployment you choose affects your business. It impacts your ability to expand, security, cost, and management responsibilities.

What Are Cloud Service Models?

Cloud service models define what a Cloud Service Provider (CSP) offers. They determine their level of service and management offerings. They separate your area of control from what the provider handles.

The main cloud service models are:

• Infrastructure as a Service (IaaS)
• Platform as a Service (PaaS)
• Software as a Service (SaaS)

These models are different layers of concepts in the whole technology stack. They determine the amount of stack you manage and what the provider manages.

IaaS gives you the highest level of control, you get the least with SaaS, and PaaS is in the middle.

The pillars of cloud computing make cloud hosting different from regular infrastructure. This will help you weigh the advantages and disadvantages of cloud computing.

The 4 Main Types of Cloud Computing Deployment

Let’s look at the four types of cloud computing deployment methods and their benefits.

1. Public Cloud

A public cloud is where a third-party provider distributes IT infrastructure among multiple users. In this cloud environment, third-party providers own and operate the resources.

Cloud providers deliver storage, servers, and applications over the public internet. They also take care of maintaining all hardware and infrastructure. In addition, it is their responsibility to handle updates and security patches.

You don’t need to worry about upgrading network equipment or changing hard drives. You focus on handling business operations. 

Also, this model enables small startups to use the same infrastructure as big companies. It uses a pay-as-you-go model to deliver resources. This means you only pay for what you use.

Examples of Public Cloud Services

Some real-world examples of public cloud services include:

• Infrastructure: Top platforms in the market include Google Cloud and Microsoft Azure. These platforms offer services like basic virtual machines and advanced AI.
• Applications: Productivity suites like Microsoft 365 use public clouds to run. Another platform relying on this model is a web-based email like Gmail. You don’t need to install anything to access them; you can do this through a browser.
• Serverless computing: An example is AWS Lambda functions that respond to events by executing code. You only need to upload the code. Then, the platform will take care of all the underlying infrastructure automatically.

Pros and Cons of the Public Cloud

Let’s explore the strengths and weaknesses of a public cloud infrastructure:

• Pros: Its ability to expand enables you to handle traffic spikes easily. Sharing resources helps you to save money by not paying for idle capacity. You can set up within minutes. Plus, you can access enterprise-level analytics and optimization without paying much.
• Cons: Data security risks due to multiple users on the same cloud. You can’t adjust settings because you have less control over infrastructure. It may be slow during peak usage times because everyone is competing for the same resources.

2. Private Cloud

A private cloud is a special computing environment for one business or user group. It is an on-premises infrastructure with firewall protection. A private computing cloud gives users greater control and data security.

This model is suitable for companies with strict standards for compliance or performance. They include banks, government agencies, and healthcare providers.

A private cloud environment can be in an organization’s data center. A third-party provider on a private network can also host it.

Subtypes of the private cloud model include:

• Managed private clouds: This is when a third party manages the infrastructure.
• Dedicated clouds: This is a secluded cloud environment within another cloud.

These types give users different levels of control and comfort.

Examples of Private Cloud Solutions

Some real-world examples of these models include:

• On-premises data centers: These platforms create dedicated cloud resources. They do this using virtualization and resource management tools. Most of these implementations depend on VMware and OpenStack to power them.
• Dedicated platforms: Solutions like to use tools like Red Hat OpenShift Dedicated. This helps them with internal application development. These platforms give developers built-in cloud tools. It also keeps the whole operation behind your firewall.
• Managed services: This involves getting private cloud services from a provider. The provider deploys, configures, and manages the cloud environment.

Pros and Cons of the Private Cloud

The advantages and disadvantages of this model are:

• Pros: Its tighter security allows you to see what everyone accesses. You also have the ability to improve every aspect of your specific workloads. You dictate your data’s location and movement. This makes it easier to comply with strict data regulations.
• Cons: The costs of hardware and software make it more expensive. You need to hire skilled, expensive engineers to maintain the infrastructure. Like traditional IT infrastructure, you can only use the resources you’ve installed.

3. Hybrid Cloud

A hybrid cloud connects private and public clouds through secure connections like APIs or VPNs. A hybrid cloud environment is a private cloud combined with one or more public cloud services.

This allows data and workloads to move between both environments. It enables you to secure your sensitive data on a private cloud. At the same time, your website grows using the public cloud for less serious operations.

According to Gartner, more than 85% of organizations will be using a hybrid or multi-cloud approach by this year. This trend shows that people need different models for various needs.

Examples of Hybrid Cloud Use Cases

Some real use cases include:

• Cloud extension: This helps businesses to grow and expand. It achieves this by connecting on-premises infrastructure with public resources. You can understand this by following up on Hybrid Cloud with AWS.
• Disaster recovery: This uses a public cloud to run your day-to-day activities. It also keeps critical data backed up to a private cloud. This strategy helps protect data and save costs.
• Application modernization: The hybrid cloud model spreads workloads across on-premises and public environments. This enables it to support DevOps and CI/CD pipelines. Also, developers can test in the cloud while keeping on-premises production running.

Pros and Cons of the Hybrid Cloud

The pros and cons of hybrid cloud computing include:

• Pros: You can decide the best environment for each workload. You don’t depend on one environment. Plus, you can avoid vendor lock-in by moving workloads between providers.
• Cons: It is challenging to integrate and manage different cloud environments. It is also difficult to maintain cost visibility across multiple platforms. You need to keep the same policies across separate systems.

4. Multi-Cloud

Multi-cloud means using two or more cloud computing services. These services would be from two or more different cloud providers. These are providers with services that suit users’ needs or reduce the risk of outage.

It could also be providers with competitive pricing. This cloud computing type often combines public and private clouds. It has organizations picking only the best services from each provider’s catalog.

A hybrid cloud strategy involving many public cloud providers is multi-cloud. However, some multi-cloud models aren’t hybrid. You must identify this difference to plan your structure.

Research shows that 87% of companies are using a multi-cloud strategy. This shows that the approach offers many practical benefits.

Examples of Multi-Cloud Environments

Some examples of these environments include:

• Best-of-breed services: This involves using AWS for data warehousing services. It also gets its AI and machine learning tools from Google Cloud. Each provider delivers excellent service in different areas.
• Platform diversity: This involves using a management system like Red Hat OpenShift. Then, running workloads across AWS, Azure, and Google Cloud Platforms. These tools make it easier to manage the complex part.
• SaaS integration: This involves including Software as a Service (SaaS) applications. You create a complete toolkit for your business by combining Saas from many vendors. For instance, using Salesforce for CRM, Slack for interaction, and Workday for HR.

Pros and Cons of the Multi-Cloud

• Pros: You are free to choose the best solutions from multiple cloud providers. You can take advantage of negotiation due to reduced vendor lock-in. You don’t experience outages because one provider’s problems don’t have much effect.
• Cons: You need advanced tools to manage the environment. It is difficult to integrate platforms due to problems with API standardization. You need more skill experts to keep everything running smoothly.
