Virtualization

Virtualization enables abstraction of hardware resources and slices a server up into multiple virtual machines, each which mimics a complete physical server

Virtualization Benefits

Has been a boon for IT for more than a decade Has rewritten the rules of the data center Has enabled heretofore unseen levels of

hardware utilization Can enables multi-tenancy

Virtualization Challenges

Significant overhead Significant repetitive work

OS deployments System configurations Challenging at scale

Virtualization Challenges

Every operating system needs individual configuration

Getting things just right takes time

Containers

Containers enable abstraction of resources at the operating system level, enabling multiple applications to share binaries while remaining isolated from one another

Container Benefits

Far less resourceoverhead

Fewer operatingsystems to support

Simpler applicationdeployment

Improved provisioning efficiency

Container Challenges

Relative newcomer to the data center Security

Difficult to isolate workloads May face challenges in multitenant environments

Some challenges when it comes to scale Not every application is suited to containers

The Hyperconvergence Revolution

At the most basic, conglomeration of compute, storage, and management The beginnings of a shared resource pool The beginning of the end of the “hamster wheel”

upgrade cycle

The technology has taken hold with these roots and grown into a tree

The Hyperconverged Data Center

The Hyperconvergence Revolution Software defined storage technologies

running alongside business workloads

The Hyperconvergence Revolution

Outcomes Simplified procurement Simplified deployment Simplified operations Simplified scalability

Remaining Challenges

Many hyperconvergence solutions are impacted by the identified virtualization problems

Virtual machines each need their own resources and operating systems

Containers vs. Virtual Machines

• A portable & rapid way to push application workloads from development production

• No dependencies on hardware or OS• Containers are thinner and lighter

weight than traditional VMs • Run several workloads on same

platform: VM or bare metal. • Docker becoming very popular with

new era of rapid deployment into the cloud

Docker

• Single server• No user• No tenant• connect to ip:port• SSL encryption supported• Option for logging in with user & password to a registry• No scheduling algorithm


Docker Swarm

• Multi server• No user• No tenant• connect to ip:port• TLS encryption supported• Similar API to docker


Docker Swarm - scheduling

• Three methods for container placement:• spread• binpack• random

• Five methods for filtering servers:• Constraint• Affinity• Port• Dependency• Health
