Demystifying Cloud Computing This is Jim

Demystifying Cloud Computing Jim’s Boss (the CIO) has asked him to “move their company to the cloud”

Demystifying Cloud Computing Jim has no idea what this means

Demystifying Cloud Computing Jim has heard of cloud computing, but is lost when it comes to the terminology

Demystifying Cloud Computing Is cloud computing just about virtualization? http: //www. computerworld. com/action/article. do? command=view. Article. Basic&article. Id=9121923

Demystifying Cloud Computing Is cloud computing just another term for Saa. S? http: //www. daniweb. com/blogs/entry 3993. html#

Demystifying Cloud Computing Is cloud computing something new? http: //www. cloudviews. org/2009/01/is-this-cloud-thing-something-new/

Demystifying Cloud Computing Is cloud computing for stupid people? ! http: //cloudcomputing. sys-con. com/node/692407

Demystifying Cloud Computing Help Jim “demystify” the cloud

Demystifying Cloud Computing Help him understand the terminology

Demystifying Cloud Computing Show Jim what applications make sense in the cloud, and why

Demystifying Cloud Computing Teach Jim the important considerations for moving to the cloud

Terminology

Terminology SOA – Service Oriented Architecture

Terminology Saa. S – Software as a Service

Terminology Web 2. 0

Terminology RIA – Rich Internet Applications

Terminology Software + Services

Terminology Are any of these cloud computing?

Terminology These are styles of application architecture

Terminology Instead, we need to look at where applications live

Where does my application live?

Where does my application live? On Premises

Where does my application live? Application runs on-premises • Bring my own machines, Buy my own connectivity, hardware, software, etc. and own • manage Completemy control and responsibility data center • Upfront capital costs for the infrastructure

Where does my application live? Hosted

Where does my application live? Application runs on-premises • Bring my own machines, Buy my own connectivity, hardware, software, etc. and own • manage Completemy control and responsibility data center • Upfront capital costs for the infrastructure Application runs at a hoster • Rent machines, connectivity, Pay someone to software application • host Lessmy control, but using fewerhardware that I specify responsibilities • Lower capital costs, but pay for fixed capacity, even if idle

Where does my application live? Cloud

Where does my application live? Application runs on-premises • Bring my own machines, Buy my own connectivity, hardware, software, etc. and own • manage Completemy control and responsibility data center • Upfront capital costs for the infrastructure Application runs at a hoster Application runs using cloud platform • Rent machines, connectivity, Pay someone to software application • host Lessmy control, but using fewerhardware that I specify responsibilities • Lower capital costs, but pay for fixed capacity, even if idle • Shared, multi-tenant Pay someone for a environment pool of computing • resources Offers pool of that can computing be applied to a set resources, of applications abstracted from infrastructure • Pay as you go

Where does my application live? Public Cloud

Where does my application live? Pool of computing resources offered from a vendor

Where does my application live? Private Cloud

Where does my application live? Pool of computing resources that lives within a self managed datacenter

Where does my application live? Pool of computing resources that lives within a datacenter with no sharing

Where does my application live? Jim now understands the style of an application, and where it lives, but who creates the application?

Where does my application live? Build vs. Buy

Build vs. Buy Where does my application live? Application runs at a hoster Application runs using cloud platform “Packaged” Application Hosted “Packaged” “Software as a Service” An application that I buy “off the shelf” and run myself An application that I buy “off the shelf” and then run at a hoster A hosted application that I buy from a vendor “Home Built” Application Hosted “Home Built” Cloud Platform An application that I develop and run myself An application that I develop myself, but run at a hoster An application that I develop myself, that I run in the cloud on-premises

Jim’s Applications

NET, ODBC, PHP Transact-SQL Synchronization C/C++ Compute Storage Data Win 32 Dynamic Tabular Data Blobs Message Queues Distributed File System VHD Content Distribution

Microsoft and Cloud Computing How does Windows Azure compare with Amazon and Google’s offerings?

Microsoft and Cloud Computing Different Models Infrastructure as a Service (Iaa. S) vs. Platform as a Service (Paa. S)

Microsoft and Cloud Computing Your Application Deployment Frameworks Deployment Web Server OS Services Operating System Provided By Amazon EC 2 Virtualized Instance Hardware Provided by Windows Azure

Microsoft and Cloud Computing Deployment Your Application Deployment Frameworks Web Server Provided by Google App. Engine OS Services Operating System Virtualized Instance Hardware Provided by Windows Azure

Your datacenter is not like a cloud datacenter

Your datacenter is not like a cloud datacenter NIC Server Rack Container Different replacement strategy

Your datacenter is not like a cloud datacenter

The Microsoft Cloud Data Center Infrastructure > Purpose-built data centre to accommodate containers at large scale § Cost $500 million, 100, 000 square foot facility (10 football fields) > 40 foot shipping containers can house as many as 2, 500 servers § Density of 10 times amount of compute in equivalent space in traditional data centre > Can deliver an average PUE of 1. 22 § Power Usage Effectiveness benchmark from The Green Grid™ consortium on energy efficiency

The Microsoft Cloud Data Center Infrastructure

The Microsoft Cloud Data Center Infrastructure

Your datacenter is not like a cloud datacenter Jim’s team’s approach to application architecture has to change

Your datacenter is not like a cloud datacenter Away from the approach of a single application running on a single machine

Your datacenter is not like a cloud datacenter Need to move from Synchronous models to Asynchronous

Your datacenter is not like a cloud datacenter Need to move from ACID transaction model to BASE transaction model

Your datacenter is not like a cloud datacenter ACID = Atomic, Consistent, Isolated, Durable (traditional transactional commit model)

Your datacenter is not like a cloud datacenter Really difficult to implement ACID transactions in distributed systems (actually an anti-pattern)

Your datacenter is not like a cloud datacenter BASE = Basically Available, Soft state, Eventually consistent

Your datacenter is not like a cloud datacenter It’s OK to be wrong, as long as consistency is achieved eventually

Your datacenter is not like a cloud datacenter Compare the cost of an apology vs. the cost of knowing for sure

Your datacenter is not like a cloud datacenter 6. 9 million copies of “The Half Blood Prince” were sold in the first 24 hours of release in the US http: //en. wikipedia. org/wiki/Harry_Potter#cite_note-bbc-hbp-record-95

Your datacenter is not like a cloud datacenter If you were the online bookstore selling those 6. 9 million copies would you optimize for ACID or BASE consistency?

Your datacenter is not like a cloud datacenter If you accidentally oversell by a few books, it’s OK to apologize

Your datacenter is not like a cloud datacenter “If my application is running in one of these massive datacenters, it’s not very “green” is it? ”

Green IT and Cloud Computing The cost to buy a server is cheaper than the cost to run (power) a server

Center-Operations-Ce. BIT. doc

Green IT and Cloud Computing Jim can barely keep his eyes open. Why is this important to him? He’s not running a cloud data center…

Green IT and Cloud Computing True; but running applications in the cloud means that Jim “inherits” the green profile (PUE) of that datacenter

Green IT and Cloud Computing May be of little consequence now, but what happens in 5, 10, 15 years time when regulations get stricter about PUE?

Green IT and Cloud Computing Fair point – good to know that you are on it

Identity in the Cloud “…I have a great new idea for a cloud application. Will it make me rich!? ! : -)”

Show me the Money!!!

Show me the Money!!! DELL Power. Edge M 600 = $4, 689

Show me the Money!!! 10 of those = $46, 890

Show me the Money!!! $0. 30 per compute hour (High CPU)

Show me the Money!!! The same $46, 890 would buy you 156, 300 compute hours

Show me the Money!!! 651. 25 compute days for 10 instances

Show me the Money!!! 21. 4 compute months for 10 instances

Show me the Money!!! Let’s not forget however… Bandwidth is not free

Show me the Money!!! Jim’s get-rich-quick idea is a new cloud based application for Blu-ray movies!
