Due to its simplicity and efficiency, Docker has gained popularity within DevOps teams and microservice architectures.
11. Libvirt
Libvirt is an open-source API and management tool that allows you to seamlessly interact with virtualization platforms such as KVM, Xen, and QEMU. Its purpose is to simplify the management of machine (VM) networks and storage by providing a view across multiple platforms. With liberty, you can. Orchestrate virtualization tasks effortlessly, enabling seamless integration with your existing systems and tools.
12. Linux Containers (LXC)
Linux Containers (LXC) is a virtualization method at the operating system level that enables running Linux instances on a single physical server. LXC utilizes features within the Linux kernel, such as groups and namespaces, to provide efficient virtualization. It boasts start-up times, overhead, and optimal utilization of resources. LXC is particularly useful in scenarios where strict isolation between applications is unnecessary.
13. Vagrant
Vagrant is a tool designed to simplify creating and managing reproducible environments. It automates the setup of development environments within machines, streamlining the development workflow. Vagrant seamlessly integrates with virtualization platforms like VirtualBox and VMware, ensuring a seamless experience for developers. By enabling the sharing and versioning of development environments, Vagrant provides setups across team members.
14. CoreOS
CoreOS (pronounced “rocket”) is a container runtime developed by CoreOS. Its primary objective is to provide efficient execution for applications. CoreOS adheres to the Unix philosophy by emphasizing simplicity, modular components, and robust security measures. It supports the accepted App Container Image format while seamlessly integrating with existing container ecosystem tools. With its security features and remarkable flexibility, RKT proves suitable for production use.
15. Hyper V
Hyper V, developed by Microsoft, is a virtualization platform that supports Windows and provides excellent compatibility with Linux. To further enhance the performance and functionality of Linux machines (VMs) on Hyper V, Microsoft offers a package called Linux Integration Services (LIS).
16. oVirt
oVirt is a virtualization platform that combines technologies like KVM, Libvirt, and GlusterFS. It offers a user management interface with features like availability and live migration. With oVirt, you can centrally manage an infrastructure’s VMs, networks, and storage. It’s flexible and scalable, making it suitable for small and large-scale deployments.
