Frequently Asked Engineering Questions

Clear answers on integration trade-offs, architecture selections, resilience, and operational ownership.

What is the practical difference between custom API development and enterprise middleware like Boomi? expand_more
Custom microservices (built in Node.js or Go) offer unmatched execution speed, ultra-low latency, and zero per-connector software license fees—making them ideal for high-frequency or cost-sensitive pipelines. Enterprise iPaaS platforms like Boomi provide standardized governance, visual low-code process flows, pre-built certified connectors, and SOC2 audit compliance out of the box. We evaluate your transaction volume, in-house technical capabilities, and total cost of ownership to recommend the optimal path.
How do you prevent data loss or duplicate records when a target platform experiences downtime? expand_more
We implement asynchronous decoupled message queues equipped with Dead-Letter Queues (DLQ) and distributed Redis idempotency locks. When an endpoint returns a 5xx status or times out, our middleware activates exponential backoff retries with randomized jitter. If the endpoint remains unreachable beyond safe thresholds, the unconsumed transaction is quarantined safely in the DLQ with full payload state intact—ready for automated or single-click manual replay once the service returns.
How are API rate limits handled across high-volume systems like Salesforce and Shopify? expand_more
We deploy adaptive token-bucket and leaky-bucket pacing engines at the gateway layer. The middleware inspects downstream rate-limit headers (e.g., Shopify's X-Shopify-Shop-Api-Call-Limit or Salesforce's 24-hour rolling quotas), dynamically throttling dispatch velocities or converting single-item requests into compound batch calls before hard platform limits are breached.
How do you secure data in transit when connecting cloud software with on-premises databases? expand_more
We avoid exposing direct public database ports. Instead, we establish dedicated IPSec VPN tunnels or AWS DirectConnect conduits, paired with local Boomi Atom runtimes or lightweight reverse-proxy connectors located behind your corporate firewall. All traffic uses TLS 1.3 encryption with mutual certificate authentication (mTLS) and payload HMAC signatures.
What documentation and maintenance runbooks do you provide upon project completion? expand_more
Every engagement concludes with complete system ownership deliverables: an architectural topology schematic, OpenAPI 3.0 specs and interactive Postman collections, a complete field-to-field canonical data dictionary, operational error-code matrices, and a comprehensive disaster-recovery and DLQ replay runbook for your internal DevOps team.
Can we migrate legacy point-to-point integrations to a modern architecture without disrupting active operations? expand_more
Yes. We execute migrations using the Strangler Fig engineering pattern. We place an integration proxy in front of legacy pipelines, systematically redirecting discrete data entities (e.g., Contacts first, Orders second, Invoices third) to the new middleware layer. During this period, bi-directional reconciliation scripts verify data parity until legacy endpoints are decommissioned with zero operational downtime.
