Jumping into a cloud migration without the right planning is like signing a contract without reading the fine print. What initially seemed straightforward can quickly become much more complicated and expensive than expected.
Enterprises that foresaw big cost savings and other ROI from their cloud spend often find themselves wrangling with multiple technical and financial issues, especially as they confront the complexity of today’s multi-cloud environments.
Over 80 percent of enterprises rely on multiple cloud computing services, for everything from CRM software to business collaboration tools. Ensuring a sustainable multi-cloud setup requires adept planning in tandem with cloud cost management. Proper planning will avoid costly surprises by providing clear insights into usage levels and their associated expenses from the start.
More specifically, it’s essential to perform a thorough cost-benefit analysis when deciding what to keep in your on-premises environment (CapEx) and what to replace with workloads in the public cloud (OpEx).
CapEx is the standard model of traditional IT procurement, while OpEx is how cloud computing services are procured. The two have very different implications for cost, control and operational flexibility.
The public cloud in particular is closely associated with cost savings because it doesn’t require any steep upfront CapEx. But it’s not always the most economical option. Fixed investments in IT equipment (e.g., for a private cloud) can actually be less expensive in certain cases. Before making the leap to the cloud, it’s advisable to have:
One of the prime reasons for cloud migration is the overall operational flexibility, beyond just potential savings, unlocked by the OpEx model.
Let’s look at how CapEx and OpEx compare as cost management strategies:
Under CapEx procurement, you make a significant upfront investment in order to acquire and maintain your critical IT assets. This comes with sunk costs that make it difficult to pivot as business requirements evolve and which can impede or kill other projects in need of funds.
Many organizations also overbuy, in order to handle peak demands, but often times this results in expensive excess capacity that lays dormant.
However, if a CapEx asset’s useful life extends beyond a year, it can typically be paid for through depreciation. This allows for tax deductions as the purchase accumulates wear and tear. You also have full control of your resources without having to rely heavily on an outside provider.
CapEx comes with many constraints, including, but not limited to:
These limitations are what make cloud an appealing upgrade option in the first place. However, physical servers still have an important place for many organizations as they are being used to build their Hybrid IT and Multi-cloud strategies.
Examples of CapEx Projects:
With OpEx, and technologies like public cloud, you gain much more flexibility than you would with CapEx:
At the same time, you lose some control over your IT infrastructure and often have to make do with limited provider tools. This makes it difficult to monitor cloud performance in the context of your business requirements.
OpEx can even become more costly than simply purchasing an equivalent CapEx asset, especially if there is no accountability for users or optimizations within the cloud services budget.
Left unchecked, the self-service at the heart of cloud frequently results in the familiar problem of overspending. This typically arises when departments and individual users provision, decommission and manage cloud instances without any consistent or governance framework.
Keeping costs from spiraling out of control is essential when consuming OpEx services.
The answer to “Should I use a CapEx or OpEx model for my infrastructure?” will always depend on the situation at hand. That said, as public cloud continues to gain popularity, so will OpEx.
It’s much easier to make pivotal decisions about your cloud environments and get the most from an OpEx deployment if you have a well-defined process for predicting your costs, along with the technical solutions for managing them.
Examples of OpEx expenditures include:
In addition to looking beyond cost savings to justify your cloud investments, it’s important to go through all your data center configurations to see where they diverge from your actual usage. This ensures you are not over-provisioning your cloud environment from the get-go .
This gap assessment, which Softchoice can assist with, will help you optimize your cloud spend through the termination of unneeded resources and the addition of bursting and elasticity to cover peaks in demand without over provisioning.
It will also deliver insights into granular expenses for IT staff, facilities and utilities, which provides a clear baseline against which to measure your cloud deployment and forecast your expenses.
After completing your assessment and determining your readiness for a cloud migration, it’s useful to have one place where you can keep tabs on your different cloud services.
The Softchoice Cloud Dashboard provides this consolidated view of accounting, management and optimization across cloud environments. This gives you actionable insights into how your OpEx and CapEx investments are affecting your cloud cost management strategy. It also lets you connect the cost of cloud services to their business value.
Over time, your cloud environment will evolve and require regular reassessment to ensure that waste is eliminated, appropriate governance measures are implemented and resources are generally being used efficiently.
