Managing Instance Groups on GCP ||
An instance group is a collection of virtual machine (VM) instances that you can manage as a single entity. Compute Engine offers two kinds of VM instance groups, managed and unmanaged: 1. Managed instance groups (MIGs) let you operate apps on multiple identical VMs. You can make your workloads scalable and highly available by taking advantage of automated MIG services, including: autoscaling, autohealing, regional (multiple zone) deployment, and automatic updating. 2. Unmanaged instance groups: let you load balance across a fleet of VMs that you manage yourself. Managed instance groups (MIGs) Use a managed instance group (MIG) for scenarios like these: 1. Stateless serving workloads, such as a website frontend. 2. Stateless batch, high-performance, or high-throughput compute workloads, such as image processing from a queue. 3. Stateful applications, such as databases, legacy applications, and long-running batch computations with checkpointing. Compute Engine maintains each of th...
