During the first quarter of 2020, cloud spending on the three main cloud service models rose by 37% to USD 29 billion. Despite the expected economic slowdown due to the pandemic, cloud spending increased by 19% in 2020, even though overall IT spending declined by 8%.
The global cloud market is projected to grow from USD 626.4 billion in 2023 to USD 1,266.4 billion by 2028. This represents a significant compound annual growth rate (CAGR) of 15.1% during the forecast period.
All this to say, cloud computing is becoming more and more popular. It allows us to access all of our information and files from any device, anywhere.
Cloud services are available in three broad service models, each of which caters to a particular set of corporate needs. Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS) are the 3 cloud computing service models.
In this post, we’ll explain the three types of cloud computing and the benefits they offer.
A Definition Of Cloud Computing
Cloud infrastructure refers to an IT environment that’s delivered on demand over the Internet. Cloud service providers offer IT services such as data centers, applications, and storage over the web. They can handle and store large amounts of data virtually. Cloud services transform IT, especially for businesses. They reduce costs by moving infrastructure to the cloud.
It’s important to distinguish between the three types of cloud deployment models—private cloud, public cloud, and hybrid cloud—each offering unique benefits and suited to different business needs.
Private Cloud
A private cloud is a cloud computing environment dedicated solely to your organization. It combines many of the benefits of cloud computing with the control and security of on-premises IT infrastructure.
Its benefits include enhanced security and control, customized according to specific business needs, ideal for organizations with stringent regulatory and data privacy requirements.
Public Cloud
Public cloud services are provided over the Internet and shared across different organizations. Service providers like AWS, Microsoft Azure, and Google Cloud offer vast computing resources to multiple customers.
Its benefits include high scalability, cost-effectiveness, and minimal maintenance. Ideal for businesses needing rapid scaling and flexibility without the burden of heavy initial investment.
Hybrid Cloud
Hybrid cloud combines private and public clouds, allowing data and applications to be shared between them. It provides greater flexibility and optimization of existing infrastructure, security, and compliance.
It offers a balanced approach, ensuring more deployment options and optimizing existing infrastructure, security, and compliance. The hybrid cloud strategy is best suited for businesses that require both the scalability of public clouds and the security of private clouds.
When examining the three main cloud models, consider the unique differences and benefits of AWS options. For example, compare Amazon Web Services (AWS) Dedicated Instances and Dedicated Hosts to select the suitable type for your needs. AWS provides options across all three deployment models, allowing businesses to choose the most appropriate environment according to their specific requirements and constraints.

The Different Cloud Service Models
Software as a Service (SaaS)
Software as a service includes any on-demand, subscription-based cloud-hosted application or software that’s run, updated, and maintained by the provider and accessed by the end-user.
Multiple end-users can access the same product without the need for separate licencing or previous experience in cloud computing and development. Getting started with an SaaS service is easy, and since the vendor takes care of everything in the cloud, no external hardware or servers are needed to manage the app or store data.
Benefits of SaaS
- Scalability. Because you’re only paying for what you need, you can add features or storage capacity as your business grows, or dial down your product features during slow periods. SaaS is good for startups and large corporations alike.
- Cost effectiveness. You subscribe to a monthly service, which includes all fees and service charges associated with using the product. The monthly cost may seem a little high, but when you consider that the storage, maintenance, upgrades, and support costs are all built into the price, you’ll see how much cheaper it can be compared to traditional software products.
- Accessibility. Imagine having everything you need to start your workday from your smartphone, tablet, or desktop. The only thing you and your employees need to access your SaaS solution is a stable internet connection. This is a great service model for businesses who rely on remote or freelance workers.
- Availability. The software is sitting in a virtual space just waiting for you to get started. The moment you decide to start using a SaaS service, all you have to do is sign up. There are no lengthy installs, no scheduled training, no waiting for a CD to be delivered. It’s ready when you are. You’ll always be using the latest version available. That allows you to get started right away.
Are There Drawbacks to Saas?
No solution is perfect, and while SaaS’s pros certainly outweigh its cons, there are a few disadvantages to using SaaS applications. For starters, the user is wholly dependent on a stable internet connection. If there’s an outage, there’s very little you can do with the software until it’s back up and running.
Secondly, if you’re storing your data across multiple cloud platforms, your data could be more vulnerable to security breaches. When looking for an SaaS provider, don’t be shy to ask about how your data will be protected.
Lastly, this pay-as-you-go service is more of a lease than full ownership, which means that your ability to customize your product or make any design changes is limited.
Examples of SaaS
Common examples of SaaS products include Google Apps, Google Workforce, Slack, Salesforce, MailChimp, Hubspot, ZenDesk, DocuSign, Dropbox, Wrike, Trello.
Platform as a Service (PaaS)
A cloud platform provides developers with a framework for building custom applications. By using a third-party service, such as Google App Engine, the developer only has to worry about designing and customizing the application or software. The PaaS solution eliminates the need to buy and set up servers, storage, and networks.
PaaS is designed for developers who already know programming languages like Python, PHP, Node.js, Ruby, Go, and Java. While PaaS isn’t geared for the general public, companies who want to develop their branded apps or software as a value-added-service to their customers may invest in PaaS services.
Benefits of PaaS
- Scalability. Developers don’t have to buy big bundles of services with features they aren’t going to use. PaaS services are start-up friendly, and allow you to pay for only what you need. When your business starts to take off, you can easily add more features or storage capacity to your monthly bill. If times are slow, you can also remove the services you aren’t using.
- Accessibility. You want your whole team to be able to work on a project at once. PaaS providers give developers the freedom to collaborate on a single project whenever they want and from wherever. All they need is an internet connection.
- Flexibility. The platform is fluid and gives the developer the freedom to use various programming languages or even integrate their own language runtimes and frameworks. If you already have developing skills, no training is necessary.
- Ease of use. PaaS providers manage all the resources needed to build your app, allowing for an immediate start without prior investment in IT infrastructure.
Are There Drawbacks to PaaS?
Similar to SaaS, PaaS does come with some disadvantages, the main one being lack of control. Customization is limited, and if there’s an internet outage or unscheduled maintenance, you have to wait for third-party vendors to start working again before you can continue with your work.
Examples of PaaS
Some popular PaaS tools include Windows Azure, Apache Stratos, AWS Elastic Beanstalk, Force.com, OpenShift, Magento Commerce Cloud, Heroku, IBM Cloud (which is both a PaaS and IaaS).

Infrastructure as a Service (IaaS)
IaaS vendors provide essential on-demand IT infrastructure: storage, virtual servers, networking, and operating systems. Users can access their framework via application programming interface (API) or dashboard.
IaaS eliminates the need for heavy-duty infrastructure costs that are normally associated with traditional setups. Businesses don’t have to buy physical hardware or allocate physical space to store these devices. On-site IT technicians can be hired as-needed instead of keeping an entire team in-house, which cuts down on HR costs.
IaaS is unique compared to the previous cloud models in that the end-user maintains a great deal of control over their data, runtime, operating systems, and software. The IaaS vendor is responsible for managing the servers, networks, and storage, but many providers offer add-on services.
This balance of control is formalized through what the industry calls the shared responsibility model — a framework that clearly delineates which security and operational duties belong to the cloud provider and which fall to the customer. Under IaaS arrangements, the provider secures the physical infrastructure, networking, and hypervisor layer, while the customer owns everything above it: the operating system, middleware, applications, and data. Understanding the cloud shared responsibility model breakdown helps organizations avoid dangerous assumptions about which party is protecting what — assumptions that often lead directly to the data loss and security gaps discussed below.
Benefits of IaaS
- Flexible. As with the previous service models, IaaS products are really flexible and allow you to select the services you require without having to pay for those you don’t.
- Manageability. Your company maintains control over your operating systems, runtime, and software.
- Startup Friendly.The IaaS cloud is a great solution for startups who don’t have a lot of upfront capital. Not needing to invest in hardware or servers frees up cash to invest in other aspects of the business. It’s also suitable for established businesses who want to migrate their IT infrastructure to the cloud.
- Scalability. An IaaS can move with your business, allowing you to add on features according to your needs. During periods of downtime, you can also let go of extra capacity or features that you aren’t using.
- Usability. While having an experienced IT engineer on your payroll is nice, you don’t really need this skill set on hand to use this service. That’s because these main services are available in the cloud, where they are managed by the IaaS providers.
- Accessible. Just add internet. Your infrastructure is available at any time from anywhere in the world and can be accessed by multiple users at once.
Are There Drawbacks to Iaas?
We mentioned that end-user control is a benefit, but in some cases, that can be seen as a disadvantage. For instance, if there’s a loss of data, it’s up to you to recover it. You also need to make sure that your data is secure to prevent cybersecurity breaches.
Like all cloud services, a stable internet connection is essential. Without it, your work may stop abruptly.
Unless you’re a cloud-first business, expect a learning curve when you migrate to an IaaS. It may take some time for your employees to get used to different workflows and processes.
Examples of IaaS
Google Compute Engine (GCE),AWS EC2, Magento 1 Enterprise Edition, Rackspace, Digital Ocean.
Other Cloud Services
There are many sorts of service models available, but the most popular cloud service providers offer software, infrastructure, and platform cloud services, which we’ll talk about later in this post.
Here are the other types of cloud service models:
Database as a Service (DbaaS)
A DbaaS gives the end-user access to a database, which they pay for as an on-demand service. The DbaaS vendor takes care of storage, and the end-user doesn’t need on-site IT infrastructure to access this service.
Mobile Backend as a Service (MbaaS)
Alternative: “This service offers a backend that mobile and web developers use to connect their apps to storage and APIs.
Anything as a Service (XaaS)
This is a catch-all term for any cloud service a business might need and that a provider might offer, which is a combination of these service models.
The main types of cloud deployment models are private, public, hybrid, or community.
As you can see, cloud service models aren’t just limited to IaaS, PaaS, and SaaS. But let’s take a closer look at the main service models and their benefits.
Why You Should Consider Moving to The Cloud
There are many benefits of cloud-based services. Moving IT processes to the cloud makes data backup and recovery easy, and many service providers offer disaster recovery assistance. Cloud solutions also reduce a company’s environmental impact, since there is no more need for paper, external hardware or the electricity needed to run them.
The three cloud service models are also cost-effective. Not only do they save on wastages, but the pay-as-you/subscription models are less expensive than traditional IT services after you consider the long list of costs associated with running these applications or in-house systems.
The cloud service models are scalable and accessible, which adds flexibility to your business structure and makes your company more appealing to a workforce that is increasingly cloud-friendly and looking for remote work opportunities.
The Environmental Impact of Cloud Computing
In recent years, the conversation around cloud service delivery models increasingly included its environmental impact and sustainability. As businesses and individuals alike seek eco-friendlier practices, it’s crucial to understand how cloud models are contributing to these efforts.

One of the most significant environmental benefits of cloud computing is the reduction of carbon footprint. Cloud service providers, like Amazon Web Services (AWS), Google Cloud, and Microsoft Azure, have made significant strides in optimizing data center efficiency. These providers utilize advanced cooling technologies, renewable energy sources, and energy-efficient hardware to minimize electricity consumption, which is one of the primary contributors to carbon emissions in the IT sector.
Resource Optimization and Decreased E-Waste
Cloud computing promotes the optimal use of resources. Traditional on-premises data centers often lead to underutilized resources, resulting in unnecessary energy consumption and increased costs. Cloud models, particularly public clouds, allow for resource pooling with multi-tenant models, ensuring that computing resources are not wasted. This efficiency not only reduces energy use but also minimizes electronic waste (e-waste), as fewer physical servers are discarded over time.
Transition to Renewable Energy
Many cloud providers are transitioning to renewable energy sources to power their data centers. For example, Google has been carbon-neutral since 2007 and aims to run on carbon-free energy 24/7 by 2030. This shift to sustainable energy sources is a critical step in reducing the overall environmental impact of the cloud computing industry.
Challenges and Future Directions
Despite these advancements, there remain challenges. Data centers still consume a significant amount of energy, and the sourcing of renewable energy is not uniform across all geographic regions. Going forward, the industry is focusing on innovative solutions like advanced cooling mechanisms, using AI for energy optimization, and exploring less energy-intensive hardware.
The shift towards cloud computing represents a more sustainable approach to managing IT resources. By reducing carbon emissions, optimizing resources, and moving towards renewable energy, cloud computing is playing a pivotal role in driving environmentally responsible technology use. As the demand for cloud services continues to grow, it becomes increasingly important for providers and users alike to prioritize sustainability in their cloud computing practices.
