Private Cloud The Good, the Bad and the Ugly

the Good, the Bad, the Ugly

The “Man with No Name” spaghetti-western

trilogy titles are pretty much like IT these days:

–A Fistful of Dollars (1964)

–the PC?

–For a Few Dollars More (1965)

–the Internet?

–The Good, the Bad and the Ugly (1966)

–the Cloud?

Defining “the Cloud”

if, at first, people were very reserved when it came to “the Cloud”...

…now many some actually want to move…

in the cloud

…but do they all know what to expect?

The real costs of IT

Essential questions

• Why would I want to build a Private Cloud?

• Who do I build it for in the end?

• What do I want to offer?

• SLA, compliance (PCI, ISO)

what do we look at when we build a

Virtual Private Cloud ?

1. budget

cost per kWh, price per U, bandwidth and connectivity costs, technical staff, etc.

2. architecture

structure, scalability, reliability, redundancy, security, flexibility

3. hardware

server (MIPS/MOPS), storage (I/O-OPS), network (1Gbps, 10Gbps, infiniband, fiber)

4. virtualization layer

5. management / automation

6. internal processes

security & incident response policies, fast problem detection/fixing,

disaster recovery, high availability, time to get a server back online

7. people

post-deployment maintenance, technical staff

SCVMM 2012 RC/CTP

SC APPCONTROLLER

A sneak peek into the future of Private Cloud management

SCVMM 2012 Beta

SCVMM 2012 - Fabric Management

Physical Server • Manage multiple hypervisors – Hyper-V, VMware, Xen

• Server hardware management – IPMI, DCMI, SMASH, Custom via Provider

• Host provisioning – from baremetal to Hyper-V to Cluster provisioning

Network • Define Logical Networks using VLANs and Subnets per datacenter

location

• Address management for Static IPs, Load Balancer VIPs and MAC addresses

• Automated provisioning of Load Balancers via Provider

Storage • Storage Management using SMI-S

• Discover storage arrays and pools

• Classify storage based on throughput and capabilities

• Discover or configure LUNs and assign to hosts and clusters

• Rapid provisioning of VMs using snap cloning of LUNs

SCVMM 2012 - Fabric Management

Update Management of Fabric Servers • Update operation control (On-demand scan and on-demand

remediation)

• Updating a Hyper-V cluster is fully automated

• Integrated with Windows Server Update Server

Dynamic Optimization (DO) • Cluster level workload balancing scheme to optimize for VM

performance

• Leverages live migration to move workloads

Power Optimization (PO) • Leverages live migration to pack more VMs per host

• Powers down servers to optimize for power utilization

Enhanced Placement • Over 100 placement checks/validation

• Support for custom placement rules

• Multi-VM deployment for Services

SCVMM 2012 - Service Lifecycle

Service Templates • Used to model a multi-tier application

• Source of truth for deployed service configuration

Applications • Built-in support for Web deploy, Server App-V, SQL DAC

• Custom command execution for other application packages

Image-based • OS separated from apps

• Composed during deployment

Servicing • Change the template and then apply that change to deployed

instances

• Upgrade domains ensures application availability during servicing

Summary

The Cloud is fun and useful… (the good)

…if you know how to use it… (the bad)

…while being prepared for anything (the ugly)

IDC predictions for 2012

http://www.idc.com/research/viewtoc.jsp?containerId=231593

1. Customers Will Face Confusing Choices as Virtualization, Cloud System

Software, and Infrastructure Automation Software Converge

2. Private Clouds Will Grow Like Gangbusters, One Use Case at a Time

3. 2012 Will Be VMware's Last Year as King of the Hill

4. Operational Complexity Will Drive Demand for Predictive Analytics and APM

5. Consumerization of IT Will Create New Management Challenges and Solutions

6. Platform as a Service Will Ramp Up Slowly Due to Lock-In Fears

7. Battle Royale Will Be Waged to Establish Linux Kernel of Cloud Computing

8. Enterprises Will Reconsider Benefits of Infrastructure Heterogeneity

9. There Will Be Layers for the Masses, Stacks for the Few

10. Windows 8 Will Launch with Split Success
