In our previous Salesforce Tutorial we have learned about What is PaaS, benefits of PaaS and Advantages of Platform as a Service. In this Salesforce Training Tutorial we are going to learn about IaaS and Top IaaS Cloud Service providers.
Introduction to IaaS
One of the main types of service models within cloud computing is Infrastructure as a Service (IaaS). This provides virtualized compute resources over the internet. IaaS is a type of cloud service where businesses and individuals can rent computer infrastructure like virtual servers, storage, and networking services on an on-demand basis. This provides businesses with the ability to scale their IT infrastructure based on demand, without huge capital investments in hardware. When considered with the rest of cloud computing, IaaS is transforming how organizations manage their IT infrastructure by enabling them to be agile and provide cost efficiency.
Full form for IaaS is “Infrastructure as a Service“. Here in IaaS the cloud service providers will provides infrastructure like servers, hosting services and storage. Servers and storage’s are the basic services provide by Cloud Service Providers.
Brief History of IaaS
As computing resources needed to be increasingly flexible and adaptable, the paradigm of IaaS was born. Old IT models forced companies to spend heavily on hardware, which led to increasing prices and maintenance costs, while scaling remained challenging. In the early 2000s, cloud computing began to gain popularity, and IaaS emerged as a solution to these issues. Thanks to IaaS, companies were able to lease virtualized computing resources as needed, avoiding the high costs of purchasing and maintaining hardware while maintaining flexibility in response to changing market demand.
Big players like Amazon Web Services (AWS), Google Cloud, and Microsoft Azure were early pioneers of the IaaS space, providing services ranging from compute power to storage and networking. Their platforms have enabled businesses, both large and small, to employ enterprise-grade infrastructure without the significant upfront costs required by traditional data centers.
How IaaS Works
At its core, IaaS is based on one of the most simple yet powerful concepts in computer science: virtualization. It abstracts physical hardware into virtual machines (VMs), allowing applications and workloads to run without concern for the underlying physical environment. These virtual machines can be scaled up or down based on demand, making IaaS highly elastic and adaptable for businesses.
IaaS providers often offer self-service portals, allowing users to provision and manage virtualized hardware through a web-based interface. This portal enables users to deploy applications, manage security, and monitor performance, all without interacting with the physical servers.
Three Main Components of IaaS:
- Compute — Virtual Machines (VMs) where workloads run.
- Storage — Cloud-based storage offerings, such as object storage and block storage.
- Networking — Virtual networks, load balancers, and firewalls that provide connectivity and security.
Key Benefits of IaaS
- Cost Savings: IaaS eliminates the need to purchase and maintain physical hardware, reducing capital expenditure. Businesses only pay for the resources they use, which helps manage operational expenses.
- Scalability: IaaS allows organizations to scale their infrastructure on-demand. Whether extra computing power is needed during peak times or less during off-peak hours, IaaS provides flexibility.
- Disaster Recovery: With built-in disaster recovery features, IaaS ensures that data and applications are replicated across various locations, providing both redundancy and business continuity.
- Global Reach: IaaS providers have data centers across the globe, enabling businesses to deploy applications closer to their customers, reducing latency and improving performance.
- Security: Top IaaS providers offer robust security features, including encryption via IPSec or SSL VPN connections and physical firewalls, ensuring a high level of protection.
Use Cases for IaaS
- Website Hosting: IaaS is ideal for hosting websites and web applications. It provides the necessary virtual infrastructure to run high-traffic applications without requiring physical servers.
- Development and Testing: IaaS allows developers to quickly create virtual machines for testing purposes, speeding up the time-to-market without hardware limitations.
- Big Data Analytics: IaaS offers the computing power needed for big data analytics, enabling businesses to analyze large volumes of data in real-time.
- Disaster Recovery and Backup: Businesses can replicate their infrastructure in the cloud, ensuring that data and applications can be restored in the event of a disaster.
Infrastructure as a Service Iaas is one of the main service required in cloud computing after SaaS and PaaS clouds.Choosing right IaaS provider is an important thing. Some many cloud Service Providers will provide Maximum Size servers and charges low cost. Depending on our requirement we like to choose 8-core , large memory machine to run our Database (or) Big database analytics.
Coming to Storage Service provided by Cloud service Providers we are able to find large block storage and also local systems connected . Servers and Storage collectively provided by Infrastructure as a Service(IaaS) Providers.
Benefits and Features of Iaas cloud.
- Infrastructure as a Service cloud has high scalability.
- Hardware cost is reduced.
- Infrastructure as a Service cloud can be accessed from anywhere using internet.
- Infrastructure as a Service provides high securitized data bases.

This table highlights some of the most prominent IaaS providers, their offerings, global presence, and notable customers.
Conclusion
IaaS enables businesses to transform the way they handle IT infrastructure by offering pay-as-you-go access to scalable and elastic computing resources. This allows organizations to trim down spending and redirect IT teams’ focus from maintaining physical hardware to driving innovation. As cloud computing continues to evolve, IaaS will remain a key enabler in helping businesses adapt to an ever-changing digital landscape.
