System & App Operations
Ongoing support for business systems and applications already in production — the same team handles incident response, version upgrades, and feature improvements.
Facing challenges like these?
- Our contract with the development vendor ended, and now we have no one to turn to when something breaks.
- OS and framework upgrades keep falling behind, always addressed after the fact.
- We want to keep improving and adding features while operating the system, but we don’t have the in-house resources.
- Handover documentation is thin, so quality drops every time we switch maintenance vendors.
The VIETIS Approach
Uptime monitoring and rapid incident response
Round-the-clock uptime monitoring paired with SLA-based incident response. Engineers who know your codebase inside out handle every issue directly.
Continuous improvement alongside maintenance
Beyond incident response and bug fixes, feature additions, UX improvements, and performance tuning are all covered within the monthly plan.
Planned resolution of technical debt
Version upgrades, security patches, and refactoring are carried out on a planned schedule, sustaining stable operation over the long term.
Scope of Support
From stable operation to continuous improvement, we cover the full range of tasks your business systems and applications need.
Uptime monitoring and alert response
Continuous monitoring of servers, applications, and databases. Anomalies trigger immediate alerts and first-line response.
Incident response and bug fixes
Root-cause analysis, emergency fixes, and recurrence prevention when incidents occur, with response times guaranteed under SLA.
Version upgrades and security response
Updates to OS, frameworks, and libraries, plus prompt patching of security vulnerabilities.
Feature additions and enhancement development
Feature additions, UX improvements, and performance tuning as your business evolves, with small-scale development covered within the monthly plan.
Database management and optimization
Ongoing scheduled backups, performance monitoring, query optimization, and capacity management.
Monthly reporting and technical consultation
Monthly reports covering system status, response history, and improvement proposals, backed by an ongoing technical consultation point of contact.
