What is IaaS?

Infrastructure as a Service (IaaS) is a cloud computing model that encourages online functionality and services without the limitations of the physical presence of the hardware and management. The IaaS is a type of service, among other counterparts, such as Software as a Service (SaaS), Platform as a Service (PaaS), and serverless. It is a cost-effective approach that allows real-time insights and non-stop continuity of work proceedings.

IaaS is a pay-as-you-go model that can be rented and charged based on the number of users. Microsoft Azure provides a cloud computing service with infrastructure like virtual machines, storage and networking resources for software and application purchase, configuration, installation and management.

Advantages of IaaS

Infrastructure as a Service offers numerous advantages to businesses. They include:

  • Allows global expansion of the services provided by the company and hence eases meeting the demand
  • Removes the hassle, avoidable expenditures and poor productivity by eliminating the need for an IT team to ensure proper maintenance, syrup and configuration of the infrastructure and other aspects (applicable in a scenario of appropriate agreement with the service provider)  
  • Serves as an effective and reliable source for business continuity by providing backup in situations of disaster
  • Offers updated and state-of-the-art security features 
  • Paces up the tasks with quick and easy access to the infrastructure within hours or minutes 

Key Components of Microsoft Azure IaaS

Let us elaborate on the components of Microsoft Azure IaaS as discussed previously: 

Virtual Machines

Virtual Machines are the platform for deploying and managing Linux and Windows operating systems in the cloud. The product can be molded according to the organization's CPU, storage, and memory needs. There are different types of virtual machines, such as IaaS services in Azure, such as A, Bs, D, E, F, G, H, Ls, M, Mv2, and N series. 

Storage

Microsoft IaaS offers different types of storage, such as: 

  • Fully managed file storage and sharing facility through the Server Message Block (SMB) protocol. The storage also includes file leasing and snapshots.
  • Blob storage stores unstructured data, including backups, documents, and media files. It is highly scalable and easily accessible to petabytes of data.
  • Table storage is suitable for storing volumes of structured data such as large-scale datasets, user data for web applications, and IoT telemetry data.
  • Disk storage offers virtual hard disks of different types, such as Ultra Disk, Standard SSD, and Premium SSD, as per the requirements. It is one of the high-performance block storage systems.
  • Queue storage offers communication between the application's various components. Its common usage encompasses job scheduling, workload management, and message processing jobs.

Networking

The networking from Microsoft IaaS allows connectivity and resource management. There are multiple networking scenarios, such as: 

  • Networking foundation for core connectivity among different Azure resources.
  • Hybrid connectivity between the resources in Azure - VPN Gateway, Virtual WAN, ExpressRoute, and Peering Service.
  • Load balancing and content delivery are the options for distributing, optimizing and managing applications and workloads.
  • Networking security protects IaaS services in Azure and web applications from Firewall and DDoS attacks.

Security and Identity

Apart from networking security, Microsoft Azure IaaS services and features for security and identity for protection are as follows:

  • Azure Key Vault: This protects sensitive information such as keys, passwords, and certificates.
  • Entra Suite: For safe access across private and public networks.
  • Azure Active Directory: To protect the user identities and unauthorized access to resources.
  • Privileged Identity Management (PIM): This manages access to a few operations and resources in Azure.
  • Azure Firewall: Offers protection by acting as a barrier between the internet and Azure virtual network.
