A Major Reason Why We Are Here Today

What is Cloud Storage?

The use of the term cloud in describing these new models arose from architecture drawings that typically used a cloud as the dominant networking icon.

The cloud conceptually represented any to any connectivity in a network, but also an abstraction of concerns such the actual connectivity and the services running in the network that accomplish that connectivity with little manual intervention.

What are the Analysts saying?

“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

“Consumer and business products, services and solutions delivered and consumed in real-time over the Internet”

– IDC

Cloud Storage Defined

This abstraction of complexity and promotion of simplicity is what primarily constitutes a cloud of resources, regardless of type.

An important part of the cloud model in general is the concept of a pool of resources that is drawn from upon demand in small increments (smaller than what you would typically purchase by buying equipment). The recent innovation that has made this possible is virtualization.

Thus cloud storage is simply the delivery of virtualized storage on demand. The formal term we proposed for this is Data Storage as a Service (DaaS).

Delivery over a network of appropriately configured virtual storage and related data services, based on a request for a given service level.

Some Basic Cloud Storage Attributes

Pay as you goSelf service provisioningScalable, ElasticRich application interfacesNo need for consumers to directly manage their own storage resource

By offloading the Storage Management, data owners can focus more on the management of data requirements ...

10

Typical Cloud User Scenarios

Escalating Amount of Data, becoming more expensive to manage

Is that old data worth keeping in my aging infrastructure?

Meet governance needsWho is in charge of deleting old data, finding it again?

New projects with a desire not to have isolated local storageDo they already go around existing storage IT practices?

Storage of important dataHow do you make sure its requirements are being met?

Storage for new Cloud Computing projectsWhere does the data live long term?

11

Cloud use case examples

Offerings in the Data Storage as a Service (DaaS) space are increasing in capabilities

Additional service levels beyond “Best Effort” storageLocal appliances that “wrap” cloud storage for legacy applicationsCloud Storage offerings that layer onto best effort services

These offerings go beyond merely storing the data, and start to account for data with differing requirements

There is a danger that the resulting complexity may cause the simplicity of cloud storage to be lostThere is an increasing “exit cost” to move from one provider to another

12

Other open questions about Clouds

Security & Privacy – What can the IT industry expect?Trusting Service Providers – Are SLAs the only measurements?Managing and/or using Cloud services across different geographies – what are the risks and constraints?What are the legal and regulatory challenges with CloudsCan Cloud be specific to Industry Verticals?How do I combine Services together?Is Internet the Cloud bottleneck? What about Cloud network services? How do I transform my IT to leverage or perform in a Cloud-like fashion?…

SNIA Motivations to launch a new Cloud Storage Initiative

The Cloud industry at-large is very active and there’s no shortage of challenges to be addressed

Compute, Storage, Service Models, Investments, DevelopmentsSLA Management, Security, Privacy, Data portability

Hundreds of questions raised about the CloudWhat, how, when… how much??Technology and services exploration & evaluationBroad IT professionals Education is needed!

Perceived value of Cloud and Cloud standardsWhat is being reported about the Cloud market may not reflect the real progress status The Cloud standards landscape is complex but not complete

Cloud market “references” are not always easy to digestUsed terminology can be confusing, often not consistentNot many best practices

Cloud Storage -TWG is busy working on developing DaaS standards (e.g. CDMI)

We need to promote this work with both developers and adopters

What is new(s)?

SNIA Cloud Data Management Interface (CDMI)Version 1.0 is a SNIA ArchitectureReady to be implemented by public and private providers

Cloud WhitepapersMulti-Tenancy Paper

Increased presence at SNW, other showsCloud Pavilion - from 3 (fall) to 6 (spring) participantsCloud Hands on LabCloud Track and SNIA Tutorials

SNIA CDMI Scope

Applicable to three types of Cloud Storage:Cloud Storage for Cloud Computing

Whitepaper at snia.org/cloud – the management interface for the lifecycle of storage in a compute cloud

Public Storage CloudBoth a Data Path for the Cloud and a Management Path for the Cloud Data

Private Cloud StorageAs well as hybrid cloudsAn API for Storage Vendors selling into Cloud based solutions

SemanticsSimple Containers and Data Objects with tagged MetadataData System Metadata expresses the data requirements

ProtocolRESTful (Representational State Transfer) HTTP as “core” interface style JSON (JavaScript Object Notation)– format of the representations are extensible

Where Can a Cloud Storage Standard help?

Common method to instantiate and manage data storage resource

Easier development, faster deployment

Common Cloud Storage metadata managementStorage, System, Network, Application, Security, Privacy

Cloud-to-Cloud data portabilityMigrate not only data but also management requirements

Easier SLA/SLO managementRequirements pushed down object-level

Easier integration in greater Cloud environments:Cloud Storage for Cloud Computing, Federated Services
