Vertical Scaling (Scale-Up) Allocate additional resources to VMs, requires a reboot, no need for distributed app logic, single-point of OS failure
Horizontal Scaling (Scale-Out) Application needs logic to work in distributed fashion (e.g. HA-Proxy and Apache Hadoop)

LINUX CONTAINERS (LXC)“Lightweight” Linux Virtualization
• Lets your run a Linux system within
another Linux system
• A container is a group of processes on a
Linux box, put together the provide an
isolated environment
• From the inside, it looks like a VM
• Externally it looks like normal processes
• “chroot on steroids”

THE PORTABILITY PROBLEMContainers compared to Hardware Virtualization
• Different file formats for virtual machines• VMware uses vmdk file format, Xen and Hyper-
V use VHD, KVM uses Raw or QCOW2• Guest images may be “processor architecture”
bound• VMware and Xen can manage SCSI devices, but
KVM cannot• KVM and Xen can use virtio drivers but not
VMware• VMware uses a proprietary agent inside the
guest OS (VMware tools) which does not work with Xen or KVM
• Xen uses VirtIo and ParaVirtualized drivers, Xen uses

DOCKER CONTAINER PACKAGINGOpen source LXC Packaging Engine
Docker is an open-source project to easily
create lightweight, portable, self-sufficient
containers from any application. The same
container that a developer builds and tests
on a laptop can run at scale, in production,
on VMs, bare metal, public clouds and
more.

WHAT IS DOCKERSystem for Managing and Deploying LXC Containers
• Compliment to LXC not a replacement
• Managed daemonized processes on Linux
using LXC
• Create ability to re-use and manage similar
applications
• Content agnostic
• Hardware agnostic
• Easy to automate
• Integrated with other tools: Chef, OpenShift,
Puppet, VMware, etc.

KUBERNETESContainer Cluster Management – Scheduler
Kubernetes builds on top of Docker to
construct a clustered container scheduling
service. Kubernetes enables users to ask
a cluster to run a set of containers. The
system will automatically pick worker
nodes to run those containers on, which
we think of more as "scheduling" than
"orchestration”
