VM to Container Modernization Advisor

Overview

This advisor helps evaluate whether an existing VM-hosted application is ready to be modernized into containers. It reviews application structure, protocol requirements, state handling, storage dependency, operating system dependency, compliance needs, operational maturity, and modernization goals.

Why This Matters

Avoid Wrong Platform Fit

Not every VM workload should move directly to Cloud Run or GKE. This tool helps identify whether the application is ready or still needs refactoring.

Reduce Migration Risk

Applications with local state, OS dependency, custom protocol needs, or tight coupling may fail if moved too quickly into containers.

Guide Cloud Run vs GKE

Simple stateless web applications may fit Cloud Run, while more complex workloads may require GKE Autopilot or a phased modernization approach.

Support Business Discussion

The result can support discovery workshops, modernization planning, cost discussions, DevOps readiness review, and compliance conversations.

Focus Areas

Architecture Pattern

Identifies whether the application is Monolith, N-Tier, or Microservices to determine the right modernization path.

Runtime & Protocol

Checks whether the workload depends on HTTP/gRPC or requires custom TCP, UDP, or proprietary protocols.

Compliance & Isolation

Reviews whether the workload has strict isolation or regulatory requirements that may limit platform choices.

Operational Readiness

Evaluates whether the team has the right DevOps maturity to manage GKE, or whether a more managed platform such as Cloud Run is more suitable.

Interactive Assessment

Complete the questions below to estimate application modernization readiness and identify whether Cloud Run, GKE, or a phased VM-to-container approach is more suitable.

01. Application State & Protocol

Does your application store user data, sessions, or files directly on the server it runs on?

Does the application use protocols other than HTTP/gRPC, such as UDP, custom TCP, or proprietary protocols?

Cloud Run is best suited for request-based HTTP/gRPC workloads. Applications that depend on custom TCP, UDP, or proprietary protocols may be better suited for GKE or Compute Engine.

02. Storage & Operating System Dependency

Does the application require persistent local disk storage?

Is your application tightly integrated with the underlying operating system?

Examples include specific OS settings, drivers, system packages, registry settings, local services, or server-level configuration.

03. Application Structure

How is your application structured today?

Monolith

A single application where most functions are tightly combined into one system.

N-Tier

The application is separated into layers such as web, application logic, and database.

Microservices

The application is broken into multiple independent services that can be deployed separately.

Does the application run background jobs, batch processes, or scheduled tasks?

How long does your application take to start and become ready to serve requests?

04. Traffic, Networking & Availability

How does the application traffic behave?

Does the application require custom networking or complex internal routing?

Does your application require always-on availability and cannot scale down when idle?

05. Compliance, Operations & Business Goal

Does the application require hardware isolation, sole-tenant hosting, or regulatory controls that restrict shared kernel environments?

How large is your DevOps or platform team for managing infrastructure?

What is the main modernization goal?
