All You Need to Know About the IaaS Model in Cloud Computing
Cloud services are booming as businesses prefer the option of gaining access to applications, processing power, and storage over the internet rather than owning and managing their own IT infrastructure. The best part of using cloud computing services is that companies only have to pay for what they are using.
Cloud computing services can be categorized under three distinct models: Infrastructure-as-a-service (IaaS), Platform-as-a-service (PaaS), and Software-as-a-service (SaaS).
This guide will help you understand the Infrastructure-as-a-Service model in-depth.
What is the Infrastructure-as-a-Service model?
The IaaS model encompasses all the fundamental cloud computing services that can be rented such as storage, physical and/or virtual servers, and networking. This model is perfect for companies that want to develop applications from scratch and prefer to control all the elements on their own. However, to opt for this model and take advantage of it, businesses need to have certain technical skills. The Infrastructure as a service model is great when businesses and IT teams want to develop innovative applications as well as reduce the time required to deploy new services and applications.
How the Infrastructure-as-a-Service (IaaS) Model Works?
IaaS is essentially the virtual or physical infrastructure that a cloud provider delivers to its customer organizations from their data centers. Companies get to utilize data centers, servers, storage, networking, and virtualization functions under this model. However, the customer can choose how much of the resource they need and can order in accordance with their requirements. By using IaaS, a company can monitor and scale its IT systems as they expand.
Here are the main components of IaaS architecture:
The customers rent a space to establish their own IT platform within the virtual data center of the IaaS cloud service provider and can access it from anywhere through the internet.
Hardware or infrastructure refers to the place where data is stored, it needs to be highly secure and must be made reliable for the user. IaaS hardware offerings include IP addresses, virtual server space, bandwidth, load balancers, and network connections.
The cloud service providers are solely responsible for the maintenance and management of the servers. These servers and networks are usually distributed across various data centers around the globe by cloud service providers to ensure that they are secure.

What are the advantages of the IaaS model?
Infrastructure as a service can be the ideal model for businesses who do not want to own and manage their own infrastructure. It allows developers to test applications much faster without having to invest in additional testing tools.
Here are some other major advantages of the IaaS model:
- Allows for Continuity and Quick Disaster Recovery: To insulate themselves from catastrophes like data security breaches or natural disasters, having a disaster recovery plan in place is crucial for businesses. Thankfully, the IaaS model looks after the protection and recovery of data as the data is stored in different locations and can be accessed during an outage or disaster.
- Helps save time and costs: Since the physical hardware which supports the IaaS model, is set up and maintained by the Cloud service provider, it saves a lot of time for the organization and cuts costs in the long run.
- Give businesses faster time to market: Staying ahead of the competition by marketing their products faster is a priority for most businesses and the IaaS model supports this by speeding up the development and deployment of new applications and services.
- Focus on core business: Instead of worrying about investing in IT infrastructure and computing resources, entrepreneurs can focus on their main business activities without getting deviated with the help of the IaaS cloud computing model.
- Highly Flexible: Depending on the requirements of the organization users can simply increase or reduce their cloud computing needs.
What are the common use cases of the IaaS model?
- Web Hosting: Website hosting using the IaaS environment is less expensive when compared to traditional web hosting and thus it has become the most common use case of this model.
- App Development and Testing: The IaaS model allows businesses to avail services on the go and this helps organizations to quickly deploy and test applications in virtual environments without having to spend a fortune on other tools.
- Internal networking: With the help of IaaS networking resources and pooled server businesses have been able to develop internal networks to run applications and store data.
- Big Data Analysis:User data is the building block for developing marketing strategies for a business. IaaS helps companies not only collect this data but also in processing them in time. This model can store, maintain, and analyze big data because it incorporates intelligent tools and can handle huge workloads. The IaaS model helps businesses improve their relationship with customers by providing them with relevant insights.
From relying on physical data centers to virtual cloud infrastructure the IaaS model has helped transform IT infrastructure. With the help of this model, organizations have realized that they can easily meet their workload demand and scale up their data environments.
