Organizations that have not yet moved to the Cloud are concerned about security and accessibility. The bigger issue—and one that isn't as obvious as the other two—is a lack of clarity about the ownership costs of on-premises versus the cloud.

We'll look at both the obvious and hidden total costs of ownership-on-premises and cloud-based solutions in this blog. Our goal is to:

  • Equip you with the necessary insights into the cost of cloud vs. on-premises to make a well-informed decision
  • Help you gain a competitive edge through scaled-up innovation and growth

The iceberg image below illustrates a comparative analysis of the complexities involved in implementing an on-premises system versus a Cloud-based one:

Cost comparison between cloud-based solutions and on-premises infrastructure:

  1. Setting up and implementation
    a. Traditional on-premises software:
    • Involves both software and hardware expenses, which drive up cost of on premises software
    • On-premises costs are expensive since it requires upgrades and maintenance
    • On-premises can cost nearly a million dollar to install, implement. Another side effect, is wastage of valuable resources

    b. Cloud-based software:
    • No hardware or software purchase is required. On-premises can cost nearly a million dollar to install, implement. Another side effect, is wastage of valuable resources On-premises can cost nearly a million dollar to install, implement. Another side effect, is wastage of valuable resources
    • Cloud services providers handle infrastructure- and upgrades-related costs. Upgrades happen seamlessly over a weekend or during off-business hours
    • Subscribers of the cloud have the flexibility to start, end or modify subscriptions according to their needs compared to on-premises solutions
  2. Cloud vs. On-Premises Security- breaches and integration
    a. Traditional on-premises software:
    • Close proximity of servers’ compromises on-premises security
    • Legacy data centers are threatened because of outdated security measures and software, leaving on-premises software open to attacks
    • Integration is complicated, laborious and requires meeting many parameters-based criteria to obtain accurate results

    b. Cloud-based software:
    • Cloud security is better when compared to on-premises. Since, physical data breaches due to negligent employees are less likely to happen since data is stored on the Cloud
    • Cloud service providers invest in cloud security protocol and software to prevent data breached and cyberattacks
    • Computing to the cloud comes with several built-in functionalities to support quick and seamless integrations
  3. Scalability
    a. Traditional on-premises software:
    • Being bound by limited physical space to accommodate hardware adds up the costs of maintaining an on-premises software
    • Handling of new infrastructure needs a larger workforce. This means hiring new employees which is an additional cost for a company

    b. Cloud-based software:
    • Cost of maintaining cloud-based software is economical in the long run since physical space constraints do not apply in this case
    • Cloud based service providers offer technical support (setting up plus maintenance)—in comparison to on-premises systems—so there is no additional cost on that score

Measurable success

"If you can't measure it, you can't improve it." – Peter Drucker, Eminent management consultant

To gauge whether you should (or should not) migrate to the Cloud, you need full visibility into your metrics. If you choose to stay with a traditional on-premises system, you are likely to endure unexpected expenditures related to maintenance, support, hardware and software (to meet unplanned requirements).
