Infrastructure as a Service (IaaS) is one of three primary models for delivering cloud services, alongside Platform as a Service (PaaS) and Software as a Service (SaaS). IaaS provides instant access to infrastructure resources as and when you need them. Each resource is offered as a separate service component, allowing you to pay only for the services you require at a particular time. The infrastructure is supplied and managed by a third-party cloud computing service provider, like Azure, and delivered via the internet. The IaaS model eliminates the need for on-premises data centres or physical servers, meaning you are only responsible for handling the OS, applications, data, and middleware.

What does Azure Infrastructure as a Service offer?

Azure IaaS provides businesses with a range of capabilities that empower them for the modern, flexible workplace.

Compute

Azure Compute provides the necessary infrastructure to run all your applications, whether new or existing. Deploy and configure Windows or Linux virtual machines (VMs) according to your specific needs and explore flexible options for migrating these VMs to Azure. Azure Compute also simplifies the deployment and management of containerised applications. With on-demand scalability and pay-as-you-go pricing, you only pay for the resources you use.

Networking

Azure IaaS delivers high-performance, high-availability, and Zero-Trust based networking services for your workloads and applications. By integrating with your existing network infrastructure, Azure Networking provides a reliable, low-latency experience for users.

Availability

Azure IaaS guarantees high availability, maintaining a 99.95% Service Level Agreement (SLA). Azure uses regions and availability zones to ensure resiliency and reliability for business-critical workloads. Each Azure region has data centres deployed within a latency-defined perimeter and connected through a regional low-latency network, ensuring optimal Azure service performance and security within a particular area. Azure availability zones (AZ) are separate locations within each Azure region that are tolerant to local failures, helping your data remain synchronised and accessible in case of a disaster.

Storage

Azure offers secure, scalable storage for workloads, applications, and data. With a range of options available, including object, block, and file storage, Azure Storage meets the demands of your data. With enterprise-grade security, Azure Storage ensures compliance standards are always met.

Security

Azure supports a Zero-Trust security approach for applications and workloads deployed on Azure IaaS. Azure’s built-in security services provide comprehensive, multi-layered protection for data, apps, and infrastructure. These services include unparalleled security intelligence, advanced threat detection, and unified security management across hybrid cloud environments.

Recovery

Azure offers a fully end-to-end backup and disaster recovery solution, ensuring you can recover data and business services efficiently in case of data corruption, accidental deletion, or service disruption. Azure backup and disaster recovery is cloud-native but can be integrated with on-premises data protection solutions, providing comprehensive protection. Your business will benefit from an 80% reduction in average data recovery time and a 97% reduction in lost end-user productivity due to data loss.
