During virtualization revolution, physical servers replaced with virtual machines to run multiple different workloads on a single server hardware but virtual machines were still large and needs some resources to run as isolated servers. Virtual machines needs to have their own operating system and applications. Also they needs to manage and configure separately. MicroVM or Micro Virtual Machine offering benefits of two different technologies and Firecracker will help you to implementing MicroVM.
Virtual Machine needs guest operating system (OS) to operates same as physical machine. Operating system is a system software and has life cycle same as other software. But what should we do about updating and upgrading guest operating systems in virtual environments. Guest Operating System Life-Cycle Most implemented services don’t need to any new features on operating system, so we should choose guest operating system with long term support. Both Windows and Linux (Some distributions) offering different of channels. You can choose a path that more stable or choose a path for have new features. Update vs Upgrade When you need to newest technologies and features on the latest major version of operating system, you have to do Upgrade. But when you are applying regular patches on operation system, you are doing Update. Keep Update Guest Operating System Operating systems’ vendors releasing patches during operating system life-cycle. Apply patches (Security or others) to keep guest operating system secure and stable as well as your services and business. Even installing service packs or upgrading to a minor version of current guest operating system is an update process and there is no limitation to do it. When We Should Upgrade Guest Operating...
