When it comes to the cost of the cloud, it is important to analyze all cloud`s models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). Those three different service models for the delivery of cloud computing provide companies with the ability to mix and match the best service model to the business needs of their organization, based on requirements and payment options and depending on the vertical industry and specific applications portfolio.

Then choose the model or combination of models that offers you the most benefits at the lowest cost. Because each model has its own costs, based on a various factors, from storage space needed to monthly traffic. To arrive at a total pricing for a cloud service, user organizations must take note of individual service elements that a provider bills for and how these are calculated. For instance, does the provider bill based on within server traffic, storage space needed, server CPU time or a combination of these factors along with other elements?

Another important factor in determining the total cost is the type of service required: dedicated server to running applications in the cloud, cloud-based backup or basic hosted storage. The easiest way to break down pricing is to focus on the primary services offered, because most cloud providers split their services into three areas: servers in the cloud, storage in the cloud, sites and applications in the cloud.

You must know that there are two pricing models for cloud computing services: pay as you use or subscription based pricing. Under first pricing model, customers are charged based on their usage and consumption of a service. This pricing structure makes users fully aware of the cost of doing business and consuming a resource, since the cost comes out of their pockets, or, in the enterprise world, their own budgets. The second model is the simplest pricing option, where the customer is billed on a fixed monthly basis. For example, a virtual machine can be offered at a fixed cost per month. The consumer is billed the same amount every month without consideration for actual usage.

To determine a pricing model that provides profit to a company that uses cloud services, it is necessary to know the direct and indirect costs of providing these services. Costs can be initial or ongoing. Initial costs, also known as capital expenditures, or CapEx, include the costs to acquire assets such as hardware and facilities (power and cooling infrastructure, server, network, and storage hardware, software licenses, including operating system and application software, cables, etc). Ongoing costs (OpEx) include all costs for keeping the business or facility running, such as: payroll, facilities, hardware and software maintenance, backend cost, etc.

When you calculate the monthly cost for cloud computing deployment, you must take into account both capital and operational expenditures. For capital expense cost items, the cost of each item needs to be amortized over the life of the item. By combining the OpEx with CapEx, the total monthly costs of the cloud deployment can be determined.

If you have a limited budget, work with projects or cannot predict which resources you'll need over a longer period, then you choose “the pay as you use” pricing model. If you require more control over the hosting budget and want to use the cloud for a longer period, you must choose the subscription based pricing.

I recently read an article published by Brett Beaubouef on his blog (Cloud ERP – New Dog, Same Fleas), about the future of ERP in the cloud. Referring to the traditional ERP, Brett called these systems „the panacea for all business automation pains”. Instead, Cloud ERP is positioned as a revolutionary approach to deploying an ERP solution.
„Practically speaking, Cloud ERP is just another deployment option available to customers. Cloud ERP provides a solution that is flexible, adaptable, scalable, efficient, and affordable. Customers can enjoy painless upgrades, rapid deployment, and easy customization along with availability “anywhere at anytime”!”, said Beaubouef.
The question that arises is the following: are there major differences between those two ERP solutions? At first sight, it seems not. The activities required for an “on premise” ERP implementation are also required for Cloud ERP and the scope and responsibility for the implementation activities are still required. And then, what would be „the key impacts that a Cloud ERP deployment will have on the implementation?”
As Brett said in his article, „from a technology perspective, Cloud ERP offers a faster implementation timeframe and provides very robust functionality”, but if the organization is not prepared to properly use the software then the value of Cloud ERP will quickly dissipate. Also, „integration will be a greater challenge in a Cloud ERP model versus an on-premise ERP model – if only because the Cloud ERP will be outside the company’s internal network”.
Than, the customizations and integrations are impacted based upon the cloud model. Regarding Brett, a customer will have greater flexibility if the customer has a dedicated instance. „If multiple customers are on single software then the Cloud ERP provider may limit the level of integrations and customizations because the software changes may have an adverse impact on all the customers on a shared instance”, specified Brett.
As a conclusion, As with every deployment model, there are advantages and disadvantages to consider. „But it is important to remember that Cloud ERP is not a short cut to success”, noted Beaubouef.
