Cloud Architecture & Migration

A cloud migration can look straightforward when teams count virtual machines and storage. The risk appears when an application depends on a database, scheduled job, identity provider, firewall rule, license server, or a person-run process that was not included in the plan. A safe migration starts by understanding what must keep working and how the...

Connecting a cloud environment to an office or data center can make applications reachable, but an overly broad network link can also expand the impact of a routing or security mistake. Hybrid design should identify which workloads need to communicate, how names resolve, and what happens if the connection fails. Map the traffic requirements List source...

Hard-coded addresses can break after migration when services move, load balancers change, or private network ranges differ. Checks to make Search configuration and source for address literals, map each dependency and owner, and replace with service discovery or managed DNS where appropriate. Test name resolution and firewall policy in staging before...

A partial migration can introduce latency, routing, identity, and availability issues between cloud services and systems that remain onsite. Checks to make Map traffic direction, protocols, identity dependencies, and failure behavior. Measure latency and throughput, secure connectivity, and test what happens if either side is unavailable. Define a plan...

Contractors may need temporary access to help with a migration, but broad or lingering privileges create exposure. Checks to make Name a sponsor, define tasks and time window, grant least-privilege roles, require strong authentication, and log administrative actions. Review access daily during critical cutovers and revoke it when work ends. When to...

Changing hosting and DNS without a sequence can point users to an unready target or leave certificates and email records behind. Checks to make Prepare and validate the target first, confirm application data sync and certificates, inventory all DNS records, and lower relevant TTLs ahead of cutover. Change records in a planned order, monitor both...

Distributed access involves identity, sharing links, device security, data residency, and collaboration patterns. Checks to make Classify information, map user groups and external collaborators, define role-based access and link expiry, and test from managed and unmanaged devices. Monitor sharing changes and have an owner review exceptions and...

Vendor availability, data residency, latency, and integration constraints may limit where a workload can move. Checks to make Confirm supported regions and service dependencies with the vendor, map data locations and cross-region flows, and validate regulatory and customer requirements. Test latency and recovery behavior in the supported target before...
