Presentation Transcript

  1. VM vs Container • Chroot on steroids • Single OS per box • Hundred of instances • Dynamic resource management, best scalability • Trivial performance overhead Xen, KVM, VMware, etc. • Hardware emulation / paravirtualization • Can run different OSson the same box • Dozens of instances • OS sprawl problem • Lower performance

  2. Usage Scenarios • CI/CD and development operations • Containers and big data • Server Consolidation • High Availability • Hosting • Dynamic Load Balancing • Security Isolation • Educational • 3

  3. Recent changes • RHEL7 kernel port • 4th gen of resource mgmt: VCMMD • CPT in upstream kernel (CRIU) • QEMU/KVM virtual machines • Bare metal installer - Virtuozzo

  4. Future directions • Mainstream kernel integration • Support of upstream kernel by mgmt tools • Clear Linux • Docker app containers • REST API • Cluster (HA, DRS, shared storage) • Integration with OpenStack

  5. Mainstream kernel integration • OpenVZ project pioneers container technology • Developing new container technology since 1999. Features then ported from OpenVZ to upstream Linux “containers”. • Already upstream (in Linux containers): • Namespaces: IPC, UTS, PID, user, network • cgroups (control groups), memory controllers (RSS, page cache), • NFS virtualization • Checkpoint and Restore • Collaborative community effort: IBM, Google, SGI, Odin • It’s still ongoing • In progress: disk thin provisioning

  6. CRIU (Checkpoint and Restore In Userspace) • First successful attempt for CPT in upstream • Powering Docker live migration • 150+ kernel patches in upstream • 3 years old • Users: Google, Samsung, Huawei, Canonical… • TCP connection migration works! • Live migration: P.Haul

  7. P.Haul (Process Hauler) • Implements live migration usage scenario • License: GPLv2

  8. LibCT • Linux containers control plane • Apache License • Allows to create container w 10 lines of C code

  9. Ploop • Linux containers control plane • Apache License • Integration with Virtuozzo, OpenVZ, Docker

  10. VCMMD (memory manager) • Manage container memory from userspace • Kernel part in mainline • License: GPLv2

  11. To sum it up • Containers scale as well as Linux does • Benefit from all Linux performance improvements • Native I/O speed, best possible performance • The more memory/CPUs the merrier • Platform-independent • as long as Linux supports it, we support it • ARM/MIPS/PPC no problem. • Plays well with others (Xen, KVM, VMware) • VM and container technologies are orthogonal • run containers and VMs side by side
