  "account": "Monolith decomposition, the modernization project with the highest failure rate, often turns into a distributed monolith with network calls where function calls once existed. AI tooling now plays a crucial role in this process, but its effectiveness depends on the specific role it fulfills. Three distinct roles exist: boundary determination, plans and measurements, and code execution.\n\nvFunction excels at the first role, observing running applications and combining dynamic tracing with static analysis to propose service boundaries based on real coupling evidence. It also measures architectural drift over time, transforming decomposition from a one-shot bet into a controlled trajectory.\n\nCAST Imaging takes the broader surveyor role, mapping dependencies across large, old, and polyglot estates to decide if decomposition is even the right investment before any boundaries are drawn. It's particularly useful for enterprises dealing with mixed-language, decades-old codebases.\n\nMorph by Modelcode covers the execution side, supporting monolith-to-microservices transformation, including one-system-in, multiple-repositories-out. It analyzes the monolith, produces a Project Spec with the target service topology for human approval, and executes milestone-by-milestone transformations as pull requests with functional verification to prevent behavior changes when function calls turn into network calls.\n\nHowever, for smaller, low-risk extractions, a skilled team with a coding agent might move faster. AWS Transform is valuable when decomposition and cloud migration are part of the same project, as it offers analysis, transformation, and infrastructure in one motion for workloads moving to AWS.\n\nModerne prepares the ground by mechanically untangling the monolith, standardizing APIs, and upgrading dependencies, reducing the risk of wrong boundaries during the actual decomposition. Coding agents like Claude Code or Codex allow individual service extractions with an engineer in the loop, but they lack a program-level plan and verification compared to platform-grade processes.\n\nIn summary, the honest answer to the failure mode of monolith decomposition is boundary selection, not code transformation. The honest first step for any tooling decision should be identifying where to cut, using evidence-based platforms like vFunction. Preparation, mechanical or fleet-scale, follows next, then execution with verification gates. If the destination is AWS, evaluate whether the hyperscaler path might collapse several steps. Skipping the first two steps often leads to failure later on.",
  "summary": "Monolith decomposition is the modernization project with the highest failure folklore. Everyone knows a team that spent eighteen months extracting services and shipped a distributed monolith with network calls where function calls used to be. The AI tooling that now targets this problem is real, but it splits into three distinct roles, and knowing which role a platform plays matters more than any…",
