Limits of a lift-and-shift approach A traditional lift-and-shift approach, where teams migrate a monolithic application directly onto hardware hosted in the cloud, may seem like the logical first step toward application transformation. Many organizations also find it useful to use an open source observability tool, such as OpenTelemetry.
