How does IaaS work?
To understand how Infrastructure as a Service (IaaS) works, let’s dive into the key aspects that enable organizations to leverage cloud computing resources effectively.
As an IaaS customer, you gain access to a wide area network (WAN), such as the internet, through which you can utilize the cloud provider’s resources and services. This allows you to install and manage various elements of an application stack without the need to invest in, maintain, and support the underlying infrastructure.
Let’s explore the key components of IaaS and how they work:
- Virtual Machines (VMs): With IaaS, you can create and deploy virtual machines, which act as the foundation for your application infrastructure. These virtual machines simulate physical servers and allow you to run multiple operating systems and applications simultaneously.
- Operating Systems: Once you have created your virtual machines, you can install the required operating systems to meet your application’s needs. Whether you prefer Windows, Linux, or other operating systems, you have the flexibility to choose what works best for your organization.
- Middleware: In an IaaS environment, you have the freedom to deploy middleware, such as application servers, message queues, and databases, to enable seamless communication and integration between different components of your application stack. This enables efficient data storage, processing, and retrieval.
- Storage Buckets: IaaS allows you to create storage buckets, which are scalable and secure repositories for storing your application data. Whether you need object storage, block storage, or file storage, you can configure and manage your storage buckets to suit your specific requirements.
In addition to these core components, the cloud provider offers a range of services to support the management and optimization of your infrastructure:
