Live migration moves a virtual machine (VM) from one host to another without interrupting access to the VM.

# data[].attributes.body
Live migration is the process of moving a running virtual machine or application from one physical server to another without shutting it down or causing downtime for users.

Key Benefits : Zero Downtime, Seamless Maintenance, Load Balancing, Energy Efficiency

# data[].attributes.body
Live migration allows running virtual machines to move between hosts with minimal or no downtime, enabling maintenance without service interruption and balancing workloads across servers.

# data[].attributes.wish_content.attachment_props.alternative_text
Live migration is the process of moving a running virtual machine between different physical machines in a way that the VM and applications running within the VM are mostly unaffected.

# data[].attributes.body
Live migration is the process of moving a running virtual machine (VM) or application from one physical server to another without shutting it down. Users experience little to no interruption while the migration happens.

How it works

1. The VM is running on Server A.

2. Its memory, CPU state, and other data are gradually copied to Server B.

3. Once almost everything is copied, the VM pauses for a tiny moment (usually milliseconds).

4. The remaining data is transferred, and the VM continues running on Server B as if nothing happened.

Benefits

No downtime – Users can continue using the application.

Maintenance without interruption – Servers can be repaired or updated while services stay online.

Better performance – Workloads can be moved away from overloaded servers.

Higher reliability – Reduces the risk of service outages if a server is having problems.

Energy saving – Unused servers can be turned off after moving their workloads elsewhere.

Real-world example

Imagine you're watching a Netflix movie. The company needs to perform maintenance on the server hosting your stream. Instead of stopping the movie, they live migrate your session to another server. You keep watching without noticing any interruption because the application continues running on the new server seamlessly.

Live migration is like moving a person from one moving train to another without making them stop their journey.

💡 What is Live Migration?

Live Migration is the process of moving a running Virtual Machine (VM) from one physical server to another without shutting it down, so users experience little or no interruption

🎭 Example

Imagine a stage play. While the actors are performing, the entire stage is quietly moved to another theater without stopping the show. The audience keeps watching and doesn't even realize the stage has changed.

🌟 Benefits of Live Migration

🚫 1. No Service Downtime

Users can continue using applications without interruptions.

⚡ 2. Better Performance

Moves VMs away from overloaded servers to improve speed.

🔧 3. Maintenance Made Easy

Servers can be upgraded or repaired without shutting down applications.

💰 4. Saves Cost & Energy

Unused servers can be turned off, reducing electricity and cooling costs.

🛡️ 5. High Availability

If a server is failing, VMs are moved to another healthy server before users notice.

Live migration is the process of moving a running virtual machine (VM) from one physical server to another without interrupting its availability or active network connections.

Benefits

Zero Downtime: No service interruption for users during transfers.

Easy Maintenance: Hardware can be repaired or upgraded without taking apps offline.

Load Balancing: VMs can be moved to less busy servers to optimize performance.

Energy Savings: Workloads can be consolidated onto fewer servers to save power.
