Software Maintenance Costs in Brief

Making up the largest part of software development life cycle (SDLC), software maintenance entails significant ongoing costs that can make up to 90% of software TCO.

ScienceSoft shares major cost considerations for software maintenance (e.g., team composition, in-house vs. outsourced maintenance, software complexity, the number of users), provides sample software maintenance fees and best practices for optimizing the costs of running software in the cloud environment.

Key Types of Software Maintenance

Since 2007, ScienceSoft has been providing software maintenance services for businesses in 30+ industries. Below, we list four software maintenance types that are the most demanded by our customers:

Corrective maintenance

Fixing errors that affect software logic, performance, design. These troubleshooting activities require urgent implementation to keep the software operational and available to users.

Adaptive maintenance

Modifying software to adapt it to the environment changes, like changing a cloud provider, switching to another operating system, or introducing new software integrations. Changes in industry regulations, enterprise policies, etc. may call for adaptive maintenance as well.

Preventive maintenance

Introducing changes to prevent deterioration of software, avoid disruptions, or make it more stable and reliable. Among the most common preventive maintenance activities are code optimization and updating software documentation for easier future maintenance.

Perfective maintenance

Enhancing software performance and usability. Perfective maintenance activities are typically based on user feedback (e.g., updating UX and UI design), new functional requirements (e.g., adding a new business rule), the need to achieve cost savings (e.g., cloud resources optimization) and enhance software performance (e.g., optimizing the storage use for quicker access to relevant data).

Major Software Maintenance Cost Factors

Software maintenance costs may vary significantly depending on a project’s specifics. Among general factors that influence the total cost of software maintenance are:

  • The type of software maintenance (corrective, adaptive, preventive, perfective), the chosen time coverage (8/5, 12/5, 24/5, 24/7), and the scope of maintenance activities.
  • Software type, its complexity, availability and fault tolerance requirements.
  • The number of application users.
  • Availability of comprehensive software documentation (knowledge base).
  • The maintenance team composition and the team members’ seniority level.

In addition, ScienceSoft recommends considering cost factors specific to the chosen sourcing model:

In-house software maintenance

  • Talent recruitment that might recur in case of high turnover.
  • Investments in the in-house staff training.
  • Regular payment of salaries and fringe benefits, tax payments, etc.

Outsourced software maintenance

  • The chosen pricing model (price per ticket, monthly subscription fee, T&M with a cap, mixed).

How to Reduce Software Costs During Maintenance

As cloud-based software is gaining traction, continuous cloud optimization has become a demanded maintenance activity requested by ScienceSoft’s clients. Below we share best practices we use to help our customers significantly minimize fees for running software in the cloud.

Rightsizing computing resources

We analyze the cloud infrastructure utilization and performance metrics to get a clear picture of software demand for computing resources. With the help of cloud rightsizing tools (e.g., AWS Compute Optimizer, Azure Migrate), we identify the underutilized resources that can be downsized, and make appropriate modifications.

ScienceSoft’s best practice: Using visual tools like heat maps helps get a better understanding of the ups and downs in the computing demand.

Terminating unused resources

Timely spotting and terminating the unused resources prevents you from being charged for the resources your software does not rely on any more.

Updating instances to the latest generation

During our maintenance projects, ScienceSoft always stays tuned with the updates of the leading cloud providers’ products. As a rule, new-generation instances offer enhanced performance and functionality. By updating the existing instances and rightsizing them according to the clients' needs, we help achieve the desired performance at a lower cost.

Evaluating the viability of reserved instances for your business

Reserved instances can help you reduce up to 75% of cloud fees, if your software demand for computing resources is unlikely to decrease within the commitment period. To make sure this is a viable investment, ScienceSoft analyzes our clients’ current usage of instances, and conducts a feasibility study for implementation of reserved instances.

Deleting obsolete snapshots

Although snapshots are efficient for restoring data, there’s no need to store all of them. In most cases, only latest snapshots are needed to recover the lost data. We can help our clients remove obsolete ones to achieve greater cost-efficiency.
