As data centers move into the cloud, IT managers need to create IaaS security strategies and implement cloud security technologies to protect their essential infrastructure. Cloud security from Skyhigh Security enables organizations to accelerate their business by giving them total visibility and control over their data in the cloud. IaaS is becoming increasingly popular across all industries, and its range of uses is expanding.

Functioning on all the same levels as IaaS, PaaS sees less use because it is only more beneficial in very specific fields. PaaS is ideal for developers where a service provider also needs to supply a platform for developing, running, and what is paas managing applications. This feature is not required in most cases, and thus, IaaS is more cost-efficient for most organizations. IaaS provides your business with a secure and reliable environment for hosting applications and data.

Storage and backups

Though IaaS can provide services at significantly lower costs than owning and managing a datacenter, prices often increase with usage. Check the billing details to learn how pricing is handled and if you can set caps or notifications for overages, and how billing details are communicated. Billing can even be unpredictable and jump more than expected with usage. Look for a provider that clearly explains the pricing model and offers predictable pricing. IaaS is advantageous to companies in scenarios where scalability and quick provisioning are key. In other words, organizations experiencing rapid growth but lacking the capital to invest in hardware are great candidates for IaaS models.

Optimal use of resources is ensured, as users can easily add or remove virtual machines, allocate additional storage, or adjust networking resources as their requirements change. All cloud service models offer on-demand access to cloud services with built-in resiliency, high availability, and access to resources on an as-needed basis. Cloud customers pay for these services under a pay-as-you-go model where they only pay for the resources and services that they use. Infrastructure as a Service (IaaS) hosts infrastructure on the public cloud and private cloud instead of in a traditional on-premises data center. The infrastructure is delivered to customers on demand while being fully managed by the service provider. The hybrid approach combines cloud and on-Premise deployment models, allowing organizations to use a combination of cloud computing and on-premise data centers to host the infrastructure and applications.

It also supports greater flexibility and scalability, helps shore up business continuity, and — when used effectively — accelerates innovation. This solution provides the end user with flexibility when it comes to hosting custom-built apps or standard software while also providing a general data center for storage. Companies that still maintain their data centers on-premises find it very difficult and expensive to extend beyond just keeping things running. To innovate and stay competitive in the marketplace, forward-looking organizations are moving their data centers to the cloud.

Organizations should carefully consider their long-term requirements and evaluate the ease of migrating between different IaaS providers. Without a doubt, the first benefit you will see from using IaaS is reduced costs. Setting up and maintaining an internal IT infrastructure can be expensive, and you will often end up with excessive features and expenses that are not necessary.


IaaS is the most basic of these three cloud services and offers the least level of resource control. Google Docs, Google Sheets and Google Presentations are all a part of the SaaS known as Google Workspace. A hypervisor is a software product that shares one physical resource with multiple virtual machines. A cloud provider uses network protocols like fiber channel, iSCSI, and NFS to split a physical network into logical partitions (or views).

With PaaS, the cloud customer is provided with a managed software platform where they can deploy applications. The runtime environment — the underlying virtual infrastructure, including storage, compute and networking, etc. — is managed by the cloud provider. Infrastructure as a Service (IaaS) is a cloud delivery model that provides on-demand computing resources over the internet, including networking, storage, and other infrastructural components. IaaS allows users to develop, grow, and scale without buying and maintaining physical hardware.

  • With both products, there’s a risk of external management data that can compromise the function and security of the tools you’re using.
  • When you partner with an IaaS provider, you pay for the luxury of not worrying about on-prem hardware.
  • When you sign up for IaaS, you can access the cloud and its physical hardware components.
  • This model allows companies to avoid investing in physical hardware and maintenance, while still having control over their own operating systems, applications and data.
  • Big players like Azure, AWS, Google, and IBM provide IaaS on public, private, and hybrid models.
  • Once deployed, the serverless app will respond to traffic and automatically scale as needed.

These services are increasingly policy-driven, enabling IaaS users to implement greater levels of automation and orchestration for important infrastructure tasks. For example, a user can implement policies to drive load balancing to maintain application availability and performance. The difference between IaaS and serverless architecture is that serverless apps are launched only as needed or as triggered.

Azure provides both PaaS and IaaS services and supports many different programming languages, tools and frameworks. With over 85% of Fortune 500 companies using Azure, the computing platform offers VMs, storage, backup, networking, databases, analytics, IoT, blockchain, machine learning, containers, security and more. The cost of using Azure depends on the specific services used, as well as factors such as usage levels and geographical region. DigitalOcean provides a simple and easy-to-use infrastructure platform that includes virtual machines, object storage and managed databases. Developers can deploy virtual machine instances called “droplets” for application and website hosting.
