Private vs. public vs. hybrid Clouds

Introduction to “The Cloud”


What is “The Cloud”?

  • The Cloud is composed of 3 basic services:

    • Infrastructure as a Service (IaaS)- Virtualized infrastructure is used to provide pre-provisioned virtual resources (servers, databases, applications, etc.). Policy-based automation allows fast provisioning of resources while maintaining security.

    • Platform as a Service (PaaS)-Provides application developers a virtual platform for their programs. This allows them to create apps that run in the Cloud, not on local machine. Since the apps are optimized for the cloud, and use resources from the cloud, the end-user experience is completely seamless.

    • Software as a Service (SaaS)-Software that is provided by a 3rd party, and accessed through web browser (i.e. Google Docs)

  • The Cloud is completely controlled by IT, but completely on-demand for users on any device from anywhere


Private Vs. Public Vs. Hybrid Cloud

Hybrid Cloud

Public Cloud

Private Cloud

All hardware and software used to create the cloud are internal to the organization.

Some parts of the environment are hosted internally, and some by a third party. Applications can be moved between the private and public clouds as needed.

A third party provider hosts the hardware and software required to create the cloud. The organization still has complete control over the environment.


Virtual machines and virtual infrastructure

Virtualization Concepts


Virtual Machines

  • A virtual machine is a software container that runs it’s own operating system and applications just like a physical computer. It has it’s own virtual hardware (motherboard, CPU, RAM, hard disks, etc.), so the OS, apps, and other computers can’t tell it’s not a physical machine.

Virtualization Layer


The Virtualization Layer

  • Directly On Top of Hardware

  • On Top of Operating System

Virtual Infrastructure

  • Combine servers, network, and storage resources from the entire datacenter into one pool.

  • Pooled resources let applications get the resources needed when they’re needed.

  • Dynamic access to resources means more can be accomplished with existing infrastructure.

The first step toward “The Cloud”


Vdi, byod, and beyond

End User Computing Virtualization Overview


What is VDI?

  • VDI stands for Virtual Desktop Infrastructure and is also referred to as desktop virtualization

  • Virtualization software such as VMware vSphere is used to create virtual desktops that can be accessed from nearly anywhere and from almost any device

  • Better security with all data stored in the datacenter and none on local machines


The VDI Backbone

  • For VDI to work you must have sufficient:

    • IOPs (read and write input/output performance per second)

    • CPU compute power

    • Memory

  • If any one of these is lacking, the overall experience will be poor

Apps

  • Vmware View Composer allows separation of Persona, Apps, and OS without changing the end user experience

  • The Virtual Desktop can be accessed from thin and thick devices and from Windows, Mac And Linux OS’s. Desktop can also be accessed from certain Smartphone devices as well.


And how hve is solving them

Problems with VDI


Some VDI Issues

  • In order to work properly the VDI environment must have sufficient IOPs, CPU, and Memory.

  • Without enough power end-user graphic performance may be poor

  • Without proper architecture, access to apps is difficult

  • If infrastructure is lacking, storing user data and user preferences can be problematic

  • Getting enough Compute and Storage power can be expensive leading to a poor ROI and high TCO

Where we’re at today

MISD Current Implementation of “The Cloud”


MISD’s Current Cloud


Legacy VDI and new hvevdi

MISD End User Computing


MISD’s Current End User Computing

  • Cisco UCS currently supporting about 100 desktops

    • Currently maxed out

    • High cost to upgrade for more users

  • 9 HVE Appliances supporting about 740 desktops

    • Easy and fast upgrade to support more users

    • Low cost of expansion


Keeping things running in the MISd cloud

Support and Troubleshooting


Local Desktop Support

  • Reduced on-site work required

  • When support is needed, Virtual Desktops behave like physical desktops
