IT ContinuumEvolution towards highly virtual and beyond to cloud

Physical Virtual IaaS

what is the challenge with current applications?

a modern application

Application Software: Web Servers, Databases, Messaging, Workflow…

HARDWARE: Servers, Switches, Load Balancers etc…

Application: Business Logic, Code & Data

EACH APPLICATION:• Many hardware & software components to

install, configure, manage• Hardware and Software is dedicated to the

Application• Scaled and Architected for Worst Possible Case• Always ON• Multiple environments – Dev, Test, pre-Prod,

Prod

Operating Software: Networking, Storage, Compute…

some real examples of the problem

app usage patterns

Successful application that is constantly used at high capacity but growth is limited and application meets all needs

Predictable BurstingServices with micro seasonality trends Peaks due to periodic increased demandIT complexity and wasted capacity

Server/Software Cost

Unpredictable Bursting

Unexpected/unplanned peak in demand Sudden spike impacts performance Can’t over provision for extreme cases

Server/Software Cost

Growing FastSuccessful services needs to grow/scale Keeping up w/ growth is big IT challenge Cannot provision hardware fast enough

Server/Software Cost

On and OffOn & off workloads (e.g. batch job)Over provisioned capacity is wasted Time to market can be cumbersome

Server/Software Cost

Total Cost on Separate Hardware

WHAT IF…• We could share the hardware

and the software across applications, across organizations…

• We could scale up/down to closely match application needs & pay only for what I am using…

• Resilience was baked in

• Building applications was easier

Cost Saving

Server/Software Cost

Server/Software Cost For BOTH systems

+ Costs to make systems resilient

Predictable BurstingServices with micro seasonality trends Peaks due to periodic increased demandIT complexity and wasted capacity

Server/Software Cost

sharing hardware AND software is where we want to be…

how…?

virtualization is the foundation

OPERATING SYSTEM (Windows)

VIRTUALIZATION (Hyper-V)

Virtual Machine• A file on a disk – the

physical machine became a software representation

• Hyper-V understands and runs this file

• VM’s configured against the physical resources

• You install an OS and all needed software in the VM

dedicated to VMs shared across VMs

the new way of doing I.T. on-premise EACH APPLICATION:

• Is a collection of Virtual Servers run on Shared Hardware

• ON when needed, OFF when not• Physical resources can be optimized• VM’s are portable, easily moved, copied• IT Ops becomes automated, faster,

cheaper• Software can provision, mange and controlWHAT IF…-> We could share on a massive scale… -> Share across companies and even geographies…?

data center innovation - softwareWindows Azure Fabric Controller• Understands the physical DC –

servers, load balancers, networking etc.

• Interacts with the OS on the physical machines and manages all aspects of virtual machines

• Multiple fabric controllers work together

• Four main responsibilities:• Datacenter resource allocation• Datacenter resource provisioning• Service lifecycle management• Service health management

cloud flavor #1: IaaS(or your virtual machines in a cloud data center)

Infrastructure as a Service:• You Build/Upload Virtual Machines to a

DC on the Internet – e.g. Windows Azure• You PAY for time/resources used and the

software in your VM’s• Your virtual machines RUN on hardware

shared with other organizations• You manage ALL aspects of the software

stack inside your virtual machines• VM’s can be moved to/from the Cloud

and your own data center• App development is unchanged

VM Library: Pre-Built O/S + App Services or your own supplied VM

Provisioning, Billing, ManagementWeb Portal, self-service provisioning

Windows Azure Fabric ControllerSoftware that manages the physical infrastructure , O/S resources and virtual machines at Global DC scale

cloud flavor #2: PaaS an exampleWindows Azure BLOB Storage Example• You SUBSCRIBE to the service and

create a unique name• You GIVE Blobs(Files) to the Storage

Service – simple API or REST• The service provides resilience and

scale, you don’t have to.• You ask for them back – you don’t care

or know where they really are (which VM’s)

• The service and the fabric controller make sure your data is stored so there is no single point of failure

• You pay for the amount of storage you use - the service manages everything

• The service can also geo-replicate, provide disaster recovery

getting a PaaS app workingWith PaaS – You don’t see VM’s• Application package contains

all the application artifacts – code, schema, data etc.

• The PaaS services and the fabric controller take care of deploying your app across the services you use

• Each Service (database, messaging, web etc.) provides scale and resilience capabilities for your apps

cloud flavor #3: SaaS

Software as a Service (SaaS)• Complete apps you use• Subscribe, on-board, normally

pay for the # of users who use the app

• No access to underlying platform

• Software may support some customizations

• Shared hardware, platform and finished software across multiple customers

• Build ON PaaS services
