We’ve answered the key questions about application maintenance

What are Application Maintenance Services?

Application maintenance services involve the ongoing support, monitoring, and enhancement of software applications to ensure their optimal performance, security, and scalability. It includes bug fixing, performance tuning, updates, compliance adjustments, and feature improvements.

Why are application maintenance services important?

Application maintenance services are essential for keeping software stable, secure, and aligned with evolving business and user needs. They minimize downtime, ensure compliance with current standards, and allow for timely updates that enhance performance and user experience. 

Who needs application maintenance?

  • Startups and SMBs without in-house maintenance teams
  • Enterprises with complex app ecosystems
  • SaaS providers needing continuous improvement and support
  • Companies undergoing digital transformation or cloud migration

What’s included in your Application Maintenance Services?

  • L1, L2, and L3 support for incident resolution and performance issues
  • Corrective maintenance (bug fixing and defect resolution)
  • Adaptive maintenance (modifying to support infrastructure or OS changes)
  • Preventive maintenance (code optimization and future-proofing)
  • Perfective maintenance (UI/UX improvements, new features)
  • Security patching and compliance updates
  • Performance monitoring and optimization

What types of applications do you support?

We maintain:

  • Web and mobile applications
  • Enterprise software (ERP, CRM, HRM, etc.)
  • Cloud-native, microservices, and containerized apps
  • SaaS platforms and API-based ecosystems
  • Legacy systems needing gradual modernization

Do you support apps built by third-party vendors?

Yes. We offer takeover support for applications developed by third parties after a code audit and knowledge transfer process.

How do you ensure application reliability?

To ensure application reliability, we implement real-time monitoring with tools like Datadog and New Relic, set up automated health checks, and use logs, metrics, and user feedback for early issue detection. We also conduct scheduled performance testing and capacity planning to prevent bottlenecks before they impact users.

How do you handle security updates and vulnerabilities?

For security, we provide continuous patch management, codebase scanning, and vulnerability monitoring using tools like OWASP ZAP and Snyk. We also review IAM policies, monitor SSL/TLS, and secure endpoints to maintain strong application defense.

Can you work with our in-house development or DevOps teams?

Yes, we’re flexible in our collaboration — whether integrating closely with your in-house Dev or DevOps teams or taking full ownership of the maintenance process as an independent partner.
