Cloud Architecture & Migration

An application may authenticate users against a directory shared with other systems. Moving it can change network access, group lookup, name resolution, or service account behavior even if the application itself is copied intact. What to check Map directory endpoints, bind accounts, group and role mappings, certificate trust, DNS dependencies, and...

A monitoring agent may depend on host permissions, outbound network access, local paths, or a specific operating system. A migrated application can appear healthy while its logs and metrics stop reaching the monitoring platform. What to check Inventory agents, credentials, collection paths, network allowlists, dashboards, and alerts. Compare data...

A migrated application may rely on an older batch processor that uses local files, fixed schedules, or unsupported libraries. The web tier can work while overnight processing fails or produces incomplete results. What to check Inventory batch schedules, input and output locations, runtime versions, service accounts, dependencies, and downstream...

An application may rely on a managed cache for sessions, rate limits, or frequently read data. Moving compute without planning cache topology, key behavior, and failover can cause widespread sign-outs or load spikes on the database. What to check Identify cache purpose, eviction and TTL rules, connection settings, persistence needs, network access, and...

An application may exchange files with a vendor through SFTP using fixed source IPs, host keys, folders, and scheduled jobs. Moving the workload can break the transfer even when application pages and databases work. What to check Inventory endpoints, host key fingerprints, credentials, source IP allowlists, file naming and timing rules, encryption, and...

An application may send notifications through a third-party relay that restricts source addresses, domains, or message volume. Moving the application can break outbound mail or change authentication and deliverability. What to check Inventory relay credentials, allowed IPs, sender domains, rate limits, bounce handling, and message types. Test password...

A cloud application may bind a license to a server identity, IP address, or machine fingerprint. Moving it can cause license checks to fail even when the software and data are otherwise available. What to check Review vendor migration terms, license activation method, host identity, outbound access, expiration, and any transfer or deactivation...

An application may retrieve credentials from a centralized vault using workload identity, network policy, or a local agent. Migration can break access even when the vault and application are unchanged. What to check Map secret references, authentication method, policies, network paths, agent requirements, and rotation behavior. Test access from the...
