Types of Cloud Services and Their Key Applications in 2025
As businesses increasingly migrate to the cloud, understanding the types of cloud services becomes critical for IT professionals and decision-makers. In 2025, cloud technologies are evolving rapidly, making it essential to grasp how each cloud service model fits into your infrastructure, project goals, or certification pathway.
Whether you are planning to get an Associate Cloud Engineer certification, undergoing Cisco ISE training, or venturing into cybersecurity incident response, learning about cloud computing models is key. At UniNets, we offer expert training to guide professionals through the intricacies of cloud technologies and corresponding certifications.
What Are Cloud Services?
Cloud services are computing resources—such as servers, storage, databases, networking, software, and analytics—provided over the internet. These enable people and businesses to use powerful IT infrastructure without having to invest in costly physical hardware.
There are three key cloud computing service models, each suited for particular use cases:
Infrastructure as a Service (IaaS)
Platform as a Service (PaaS)
Software as a Service (SaaS)
The Three Main Cloud Computing Service Models
1. Infrastructure as a Service (IaaS)
IaaS delivers virtualized infrastructure via the internet. These are virtual machines, storage, and network resources.
Major Applications:
Web hosting
Development environments for applications
Disaster recovery and backup
High-performance computing
Why it Matters in 2025:
IaaS enables companies to quickly scale while they pay for the amount of resources used. For IT professionals seeking Google Associate Cloud Engineer certification, it is important to know IaaS because it is the foundation of offerings such as Google Compute Engine.
2. Platform as a Service (PaaS)
PaaS offers a platform for developers to develop, test, and deploy applications without having to deal with the underlying infrastructure.
Major Applications:
Fast app development
Business intelligence
Microservices and containerized apps
Relevance in Certifications:
The students of cloud engineer certification programs need to understand how platforms such as Google App Engine function. PaaS is a vital part of DevOps pipelines and cloud-native app development.
3. Software as a Service (SaaS)
SaaS provides applications via the web. They are accessed through browsers, with no installations necessary.
Key Applications:
Email platforms
Customer Relationship Management (CRM) tools
Collaboration software
Impact:
SaaS is the most customer-facing model of the cloud and is used in most industries. It lowers IT workload and provides up-to-date consistency and scalability.
Cloud Computing Models in 2025: Trends and Innovations
With the progression of the industry, new models of cloud computing are increasing in popularity:
Hybrid Cloud: Integration of on-premises and cloud resources
Multi-Cloud: Consuming services of more than one provider (e.g., Google Cloud, AWS, Azure)
Serverless Computing: Running code without server management
Edge Computing: Processing data nearer to the source (IoT, autonomous cars)
These new models are frequently addressed in certifications such as the Google Cloud Engineer certification and in UniNets’ cloud computing training.
Cloud Service Types by Deployment Model
Besides the service models, cloud services can be deployed by:
Public Cloud (e.g., GCP, AWS)
Private Cloud (on-premises hardware)
Hybrid Cloud (Both of them)
Knowing these differences is important for associate cloud engineers because it will impact architecture decisions, particularly in regards to cybersecurity incident response.
Why It’s Critical for Certifications
Knowledge of cloud service models is a fundamental prerequisite for certifications like:
Associate Cloud Engineer Certification
Know how to deploy and manage cloud infrastructure with an emphasis on security, scalability, and cost savings.
Google Cloud Engineer Certification
Master advanced GCP tools, services, and deployment models, such as cloud monitoring and policy management.
Cisco ISE Training
Gain a knowledge of identity and access control in cloud and hybrid environments. Cyber security incident response strategy is supported by concepts of the Cisco ISE course.
Cloud Services and Cybersecurity
Security becomes a great concern while using cloud infrastructure. Understanding what is incident response in cyber security becomes imperative when data gets stored between virtual environments.
Key Areas to Understand:
Cyber incident response: The formal methodology of managing breaches
What is cyber incident response: Discovery, containment, and recovery
Cybersecurity incident response: Tends to incorporate automation and AI tools in 2025
Cisco ISE training is worth having for cloud professionals who wish to implement network security policies in a hybrid or cloud-native setup.
