3 Constant, increasing reliance on IT The Evolution of IT Constant, increasing reliance on IT The Decade of Business System Modernization estment IT Inve

4 Today s IT Challenges Do More with Less Increasing Business Demands Explosion of new Data Requirements Growing Complexity Burden of Legacy Systems Staffing Low Utilization $$ Value of data Amount of data (40 to 100%) Budget and IT Staff cuts Storage management costs (3-5x) Time

5 Paradigm Shifts: Storage 3.0 Cloud / Virtualized Storage Networked Storage (NAS/SAN) consolidates and virtualizes disks (capacity) for improved provisioning flexibility and efficiency Cloud-based or Virtualized Storage consolidates and virtualizes disks and controllers to scale capacity and performance, to provide enhanced resiliency, while reducing both CAPEX and OPEX for service providers and end-users

6 The Evolution of Data Unstructured data and content depots are driving data growth Consumption o of Disk Capacity by Data Type Unstructured Content Depots: Data: s Unchanging reference Office data Productivity Data (.doc, Apple.ppt, itunes, etc.) MySpace, Digital Google / Medical Images Rich media 25 y Source: IDC, 2008

7 Cloud Definitions Cloud is a way of using technology, not a technology in itself it's a self-service, on-demand pay-per-use model. Consolidation, virtualization and automation strategies will be the catalysts behind Cloud adoption. The 451 Group Key characteristics of the Cloud are: The ability to scale and provision dynamically in a cost efficient way The ability to make the most of that power without having to manage the complexity of the underlying technology The Cloud architecture can be private (hosted within an organization s firewall) or public (hosted on the internet), and hybrid use cases

8 NIST* Cloud Computing Attributes On-demand self-service A consumer can unilaterally provision computing capabilities as needed automatically without requiring human interaction with each service s provider. Broad network access Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms. Resource Pooling The provider s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. Rapid Elasticity Capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. Measured Service Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service. * National Institute of Standards and Technologies nist.gov

9 Cloud Storage Spending Storage will outgrow all other types of Cloud IT spend Important to choose the right storage vendor Important to choose the right storage vendor Quality, longevity Features and functionality Price/performance, cost per terabyte, price granularity

10 SPI* Service Model Application Domains Service De elivery Mo dels Software as-a-service (SaaS) Platform-as-a-Service (Paas) Infrastructure-as-a-Service t (IaaS) Public Public Pr rivate Public Hybrid Priva ate Pu ublic Public Private SOURCE: Cloud Security and Privacy, Mather, Kumaraswamy, Latif, 2009, O Reilly, ISBN: * Service Provider Interface

11 Characteristics of Public Cloud Illusion of infinite resources available on demand Elimination of an upfront commitment by cloud users Ability to pay for use on a short term basis as needed Services accessed over the Internet Service Level Agreement Very Scalable Internet Data Center Very Scalable Internet Data Center Public Cloud Amazon Web Svcs Google App Engine Microsoft Azure Very Scalable Internet Data Center Very Scalable Internet Data Center

12 Characteristics of Private Cloud Private Cloud = Services delivered behind the firewall from Cloud-like infrastructure Internal Private Cloud Dynamic Data Center External Private Cloud Hosting and Managed Services External Private Content Cloud Enterprise/National DC Automation Firewall / Security Virtualized Infrastructure Servers Network Tiered Storage Service Provider DC (E.g. Telco, xsp ) -Application Host - Managed Services Servers Networks Storage CDN Regional Data Center Content Distribution Cloud Content Depot Regional Data Center Regional Data Center Enterprise Enterprise DC 2 DC 2 Enterprise Service DC 2 Provider DC 2

13 Characteristics of Hybrid Cloud Internal Private Cloud Dynamic Data Center External Private Cloud Hosting and Managed Services External Private Content Cloud Enterprise/National DC Automation Firewall / Security Virtualized Infrastructure Servers Network Tiered Storage Hybrid Service Provider DC (E.g. Telco, xsp ) -Application Host - Managed Services Servers Hybrid Networks Storage CDN Hybrid Regional Data Center Content Distribution Cloud Content Depot Regional Data Center Regional Data Center Enterprise Enterprise DC 2 DC 2 Enterprise Service DC 2 Provider DC 2

14 Where is the cloud deployed? Where Is Cloud Deployed? Hybrid Independent App and Data Cloud Compute and Storage Infrastructure /app Private/ Internal Public/ External The Cloud data

15 Lo ower SLA A Simple Taxonomy: Cloud Services Public Clouds Non IT Public Clouds Consumer General access Low security Low SLAs Cheap or free Examples: Facebook, LinkedIn, itunes Examples: Yahoo Mail, Google Apps, SWaaS Public Clouds SME/Enterprise Hybrid Clouds Limited access Inter/Intranet delivery Defined SLAs Security Examples: Pay per use $GB Utility Examples: Trusted SP/SI/Telco Hig gher SLA Private External Customers only Private Internal Employees Only Inter/Intranet delivery Data Center Security/firewalls Enterprise SLAs Examples: SaaS, STaaS Examples: IaaS

16 Why Cloud Offload storage acquisition and management costs Move from larger CAPEX => smaller OPEX Move from Fixed Costs => Variable Costs Provide elasticity Grow or shrink capacity and resources on demand Simplify deployments Speed time-to-value Support business user groups requirements Speed time-to-markett t Mitigate risk and maintain control Enable choice Multiple SLA options Value-added features

17 IT Evolution - Virtualization The role of storage virtualization in the data center has become more strategic to sustainable efficient infrastructures Past focus on storage infrastructure Application Storage Silos Direct Attached Storage Shared Storage Silos SAN Attached Storage Application Operational redundancy Improved consolidation Siloed management Low utilization rates No resource sharing Homogeneous management

18 IT Evolution: Active management of Data and Information Over Time Application/owner policy Taxonomy, collaboration, business process of application and data Data/information requestors Common data governance Archive Software Document management File System Home Grown Application Virtualization and Dereferencing Index, Discovery and Search PACS Dynamic lifecycle management Seamless search, discovery and retrieval across apps, media, time. SSD SAS SATA Spin Down Central data repurposing SAT A SCALE Data Center Information Center

19 Near Future: The Information Centre Information Cloud Public Cloud SSD Infrastructure Cloud SAS S SATA Spin Down SA TA Information Virtualization Private Cloud Private Cloud Private Cloud Private Cloud Personal Cloud Effective information center depends on virtualized data center Seamless access and integration of virtualized data Object catalog and index allows application independent information clouds

24 What Cloud Will Inevitably Challenge The Network with a big N Can Networks cope with the increase in data traffic due to Clouds? Security & Privacy, Technologies & Policies Will it be safe enough and can I manage it to my standards? Data Centres Service Subscriber: What do I need to do to consume Cloud services efficiently? Service Provider: What Do I need to do to provide adequate services at the right price level? Source of IT Which services are likely candidates to be shifted to the Clouds? Expertise for Data Centres / IT Will data center jobs evolve? IT Services Delivery Who s in charge? Software models Which Software can really take advantage of Cloud services? SLA Management Beyond SLA/SLO definition, how much can be automated? Combining Clouds How difficult will it be to have a multi-cloud strategy? Standards & Best Practices What safeguards exist / will exist to protect my investments? IT purchase/spending Cycles What are the new priorities?

25 Top Threats to Cloud Computing 1. Abuse and Nefarious Use of Cloud Computing (IaaS & PaaS) 2. Insecure Interfaces and APIs (IaaS, PaaS, SaaS) S) 3. Malicious Insiders (IaaS, PaaS, SaaS) 4. Shared Technology Issues (IaaS) 5. Data Loss or Leakage (IaaS, PaaS, SaaS) 6. Account or Service Hijacking (IaaS, PaaS, SaaS) 7. Unknown Risk Profile (IaaS, PaaS, SaaS) SOURCE: Cloud Security Alliance, Top Threats to Cloud Computing, Version 1.0, 2010,

26 Simplify The Management Of Cloud Storage Stack A il Cl d with ith Vi t li d Agile Cloud Virtualized and Integrated Block, File and Object

27 Keep It Simple Start with simple Cloud Use Cases E.g. File Tiering E.g. Data Protection E.g. Data Archiving Not all data is eligible to Cloud Storage Delineate your Cloud solutions perimeter Application, Server, Storage Learn about Cloud Storage through low-risk projects Measure your success!

28 Future Industry Steps: Cloud Peering Source: SNIA Cloud Storage Initiative

29 Looking Into Cloud Storage Standards Storage standards can help: Common method to instantiate and manage data storage resource Easier development, faster deployment Common Cloud Storage metadata management Storage, System, Network, Application, Security, Privacy Cloud-to-Cloud data portability Migrate not only data but also management requirements Easier SLA/SLO management Requirements pushed down object-level Easier integration in greater Cloud environments: Cloud Storage for Cloud Computing, Federated Services Source: SNIA Cloud Storage Initiative

30 Some Final Thoughts Cloud is yet another step toward the Service-Orientation of IT to become even more business efficient Cloud is also another phase in the decoupling of logical & physical IT resources There will be many different type of Clouds Enterprise will embrace various versions of (Hybrid) Clouds Integration is an important key to successful Cloud deployments Cloud stacks & services should empower providers to be trusted Data Storage will remain at the heart of popular Cloud Services Financial incentives and Quality of Cloud Services will determine the success of Clouds Hitachi Data Systems can help you planning your Cloud Storage projects for a more Agile IT!
