However, don't lose hope! There are ways to access and use IBM i, even if you don't have a Power Systems server sitting in your basement. The most common approach is through a hosted environment or a cloud-based service. This means you're essentially renting access to an IBM i environment that's already set up and ready to go. Providers like IBM Cloud offer IBM i as a service, allowing you to run your applications and manage your data without the upfront cost and hassle of owning and maintaining the hardware. These cloud environments provide all the necessary infrastructure, including the operating system, database, and security features. It's like renting an apartment instead of buying a house – you get all the benefits without the long-term commitment and maintenance responsibilities.

Another option is to use a virtualized environment. You can create a virtual machine on your existing hardware and install IBM i on it. However, this typically requires a valid IBM i license and the necessary installation media. Virtualization allows you to run multiple operating systems on a single physical machine, maximizing hardware utilization. It's a great option for developers or businesses that want to test and develop applications on IBM i without investing in dedicated hardware. Keep in mind that setting up a virtualized environment can be technically challenging and may require some expertise in virtualization technologies.
