Infrastructure as a Service eliminates the need to spend capital on upgrading physical hardware and moves businesses into an Operating Expense (OpEx) model. The business doesn't have to manage or control the underlying cloud physical infrastructure but still has control over operating systems, storage, and applications. Virtual servers offer numerous advantages over physical servers. Manageability of virtual servers is simpler because you can easily connect to the server’s console remotely without the need for special remote access hardware. You can also clone virtual servers and create templates for quick replication. Lastly, virtual servers all see the same virtual hardware to ensure that your applications all run on similar hardware to eliminate problems that may arise from dissimilar hardware. Infrastructure as a Service has a pay-as-you-go model which allows you to scale up or down depending on your needs. When it comes to pricey hardware, an organization can save a lot by using RapidScale’s secure infrastructure and paying for only what was used. With IaaS an organization can eliminate the many negative aspects of IT expansion, especially issues with in-house infrastructure, while still receiving the processing power and storage that you need to run business-critical applications.
