What are application maintenance services?

Application maintenance services ensure your software remains secure, up to date and performing as expected through monitoring, updates and continuous improvement.

What is included in managed application support services?

Managed application support services include monitoring, L2 incident management, performance optimisation, updates and continuous improvement, delivered by developer-led teams who understand your codebase.

How do application support and maintenance services reduce costs?

NashTech’s application support and maintenance services help to reduce unplanned downtime, optimise infrastructure usage and prevent costly failures through proactive management.

Do you only support applications developed by NashTech?

No. We provide application management and support services for software developed by NashTech, third-party vendors and in-house teams. We begin by assessing your application's architecture, codebase, infrastructure and support requirements, then create a tailored support model to improve performance, stability and long-term maintainability.

Can NashTech support legacy systems?

Yes. We support and modernise legacy systems to improve performance, security and scalability. Our core strengths include technology stacks such as .NET, Java, Node, Python and React/Angular on Azure and AWS.

How do you ensure high availability?

Through proactive monitoring, rapid incident resolution and continuous performance tuning.

Do you offer cloud cost optimisation?

Yes, our cloud financial management services help optimise spend and improve efficiency.

How quickly can you onboard?

We follow a structured onboarding process to ensure a smooth transition with minimal disruption. We’ll work with you to map out what that might look like.

Keep applications running smoothly

Application maintenance services that keep your business moving

Whether we built your application or not, we ensure continuity, performance and long-term value from day one. Our developer-led application maintenance services keep systems stable, costs controlled and performance optimised, with people who know your codebase inside and out.

Struggling with application performance, cost and complexity?

Modern applications are under constant pressure. Our application support and maintenance services shift you from reactive firefighting to continuous optimisation.

Two approaches, one result:

We build your application and continue to support it. The same engineers stay with you, so knowledge is retained, context is never lost and improvements happen faster.
For applications developed by others, we follow a structured onboarding model including knowledge capture, shadowing and reverse shadowing. This ensures a smooth transition with minimal disruption.

Too much time firefighting
Your team is tied up resolving incidents instead of delivering innovation.
Costs keep creeping up
Uncontrolled infrastructure and maintenance costs impact your budget.
Performance impacts experience
Slow or unreliable applications frustrate users and damage trust.
Lack of visibility and control
Without insight, issues escalate before you can act.
