Application Monitoring & Communication

We check application health, alert the right people, and publish status pages others can read without logging in. Echo runs scheduled HTTP, TCP, ICMP, and heartbeat checks with email, Slack, and webhook alerts. We also build custom monitoring.

What we deliver

  • Scheduled uptime checks across services and endpoints
  • Email, Slack, and webhook alerting on status changes
  • Public status pages, embed widgets, and JSON APIs
  • Custom monitoring integrations for client environments

Stack: React · TypeScript · Python · FastAPI · Go · PostgreSQL · Redis · Docker

Backup & DRInfrastructure

Backup and disaster recovery

Backups need tested restores, not only scheduled copies. We design retention, deduplication, and failover to match your recovery windows — including runbooks. On-prem products include local backup; this service covers infrastructure DR.

What we deliver

  • Automated backup orchestration and deduplication
  • Cross-region replication aligned to RTO/RPO targets
  • Integrity verification and tested restore procedures
  • Documented runbooks for compliance-driven retention

Embedded and industrial automation

Firmware and protocol work for factory and field systems — C/C++, RTOS, PLC/SCADA, edge gateways, and industrial protocols through to operator-visible telemetry.

What we deliver

  • Firmware and RTOS development for deterministic control
  • PLC and SCADA integration for shop-floor automation
  • Edge-to-cloud pipelines for operators and maintenance teams
  • Industrial protocol integration under load

FAQ

Monitoring, embedded, and IoT questions

What is application monitoring and why does my business need it?
Application monitoring checks whether sites, APIs, and jobs respond as expected — and alerts you when they do not. Downtime you discover from customers costs more than proactive alerts. Echo is our live product for scheduled checks and public status pages; we also build custom monitoring stacks.
What is the difference between application monitoring and server monitoring?
Server monitoring watches CPU, disk, and host health. Application monitoring asks whether the user-facing path works (HTTP, TCP, heartbeats). You usually need both: hosts can be “up” while checkout still fails. We focus on application and dependency checks that map to real customer impact.
How do we set up alerts without alert fatigue?
Alert on state changes that someone will act on, route by severity, and suppress flapping. Echo supports email/Slack/webhooks with clear status history; for custom setups we design thresholds, quiet hours, and escalation so the night page is rare and useful.
What are the main challenges in embedded systems projects?
Determinism, power, peripherals, and long hardware lifetimes. Soft deadlines that work on the web fail on the shop floor. Zolestio engineers firmware and industrial integrations (C/C++, RTOS, PLC/SCADA) with measurable control behaviour and operator-visible telemetry.
What is the difference between embedded and firmware engineering?
Firmware is the software that runs on device MCUs/SoCs; embedded engineering often includes that firmware plus board bring-up, protocols, and the edge/cloud path operators use. We cover firmware through gateway and dashboard work so the product is complete, not just a binary on a chip.
How much does it cost to build an IoT solution?
Budget covers hardware revisions, firmware, connectivity (MQTT/HTTP), cloud ingestion, OTA, security/provisioning, and companion apps. Prototypes are cheaper than fleet-hardened signed updates. Contact us with device type, fleet size, and update requirements for a scoped estimate.
Is IoT security a real concern?
Yes. Unmanaged devices become network footholds. We design identity, secure provisioning, signed OTA, and least-privilege cloud access from the first hardware revision — not as a late bolt-on.
What is the difference between IoT and IIoT?
IoT often means consumer or general connected products; IIoT (industrial IoT) stresses uptime, safety, and plant protocols. Our operations practice spans both: appliance-style fleets with MQTT/OTA, and industrial automation with PLC/SCADA and edge gateways.
