Saving money is your key priority. Costs associated with IaaS are typically on a usage basis, as well as the connectivity required to access IaaS. Fees vary significantly with the Service Levels purchased. IaaS helps you better understand and manage your business risks and IT infrastructure costs.
You want to avoid latency and have limited options with local IaaS providers. IaaS is often concentrated in areas with higher demand, so the infrastructure can be scaled, meaning getting your traffic to the IaaS service may add latency to a solution. Additionally, if connectivity to your remote location is expensive, outsourcing data to be processed and returned may provide additional costs and latency to a solution.
Ensure that you lock in a service-level agreement that meets your business needs. Service levels can significantly impact the cost of a solution, so you must agree upon a quota that aligns with your requirements.
Pricing is most commonly pay-as-you-go and billed for usage in arrears. Custom solutions are better suited to specialists, and larger-scale solutions have more cost-effective monthly fees; however, they are less flexible because the infrastructure is dedicated to a single customer.
