Google Compute Engine vs Google Migrate to Containers

Google Compute Engine is an infrastructure-as-a-service product for running self-managed virtual machines on Google infrastructure. Choose a predefined machine type or configure a custom VM with 1 to 96 vCPUs and up to 8.0 GB of memory per core. Linux and Windows VMs are supported, with images including Debian, Ubuntu, FreeBSD, and Windows Server. Storage options include Persistent Disk and Local SSD. Managed instance groups can add VMs for peak load and replace underperforming instances; live migration can move a VM to another host in the same zone when its host goes down. Confidential VMs encrypt data in use, while Shielded VMs defend against rootkits and bootkits. The service integrates with Cloud Storage, App Engine, and BigQuery, and resources can be controlled through a REST-based API. Its free tier is free, within monthly limits and eligible US regions. Pay-as-you-go pricing is usage-based, with VM resources billed after a one-minute minimum in one-second increments.

Google Migrate to Containers is a free, self-hosted tool for moving applications from virtual machines or servers into containers without rewriting or re-architecting them. Its local CLI copies a source VM file system, analyzes it, creates a migration plan, and generates deployment artifacts. It can optionally move data files to persistent volumes. Sources include VMware and Compute Engine VMs, and destinations include Google Kubernetes Engine, GKE Autopilot clusters, and Cloud Run. Supported workloads include Linux applications, IBM WebSphere, JBoss, Apache, Tomcat, WordPress, and Windows IIS applications. Linux workloads can be handled locally in offline mode or on a local network without runtime internet downloads. A local machine needs Docker and several gigabytes of storage. Google recommends assessing workload fit first. The console UI, migctl, and processing-cluster CRDs were discontinued in May 2024; Google directs users to the local CLI. Migration has no charge, while other Google Cloud services cost separately.
