Cloud Architecture & Migration

File migration can preserve data but lose access control, ownership, timestamps, or link behavior if the target model differs. Checks to make Inventory shares and permission groups, identify inherited and exceptional ACLs, map identities in a test copy, and compare access results with representative users. Pilot a department, communicate path changes,...

A server-size estimate misses storage growth, data transfer, managed services, backup retention, licensing, support, and the cost of running old and new environments together. Checks to make Collect usage over a representative period, identify data transfer paths, estimate storage and backup growth, map licensing, and include migration overlap and...

Migration order should reflect value, dependencies, risk, and readiness rather than server size alone. Checks to make Inventory owners, sensitivity, integrations, recovery, licensing, and network dependencies. Pilot a reversible workload with acceptance criteria. When to get help Cloud planning can map dependencies and migration waves. Informatix...

DNS changes are a common part of a cloud migration, but lowering the TTL at the last minute does not immediately clear records already cached by resolvers. Some clients also retain connections or ignore expected caching behavior. Prepare the name change Record current DNS values and TTLs, confirm authoritative nameservers, and decide how long the old...

An application can appear stateless while quietly storing uploads, generated reports, or session data on a local server disk. After migration to multiple replaceable instances, users may see missing files or inconsistent behavior if each instance has a separate filesystem. Trace file writes and reads Review application configuration, code paths,...

A cloud region outage can affect compute, storage, identity endpoints, and managed services at the same time. A secondary environment helps only if it can serve the business workflow with current data and required dependencies. The recovery design should reflect the outage the organization intends to withstand. Map regional dependencies List which...

A region change affects latency, data residency, networking, managed services, recovery, and sometimes provider-specific features. Checks to make Inventory dependencies and data locations, confirm service availability and compliance constraints, measure latency to users, replicate and validate data, then test failover and rollback. Plan DNS and...

Cloud bills can rise after a migration even when virtual machine sizes look reasonable. Applications may now send data between regions, availability zones, storage tiers, or external networks more often than they did on the old platform. Repeated backups, analytics extracts, and service-to-service calls can turn small design assumptions into recurring...
