VISION Cloud Virtualized Storage
Services Foundation for the Future Internet Architect and build the next generation, standard-based, scalable, low-cost and secure cloud storage system Key Innovations: • Raise Abstraction Level of Storage • Computational Storage • Content-Centric Storage • Advanced Capabilities • Data Mobility and Federation Four use cases to demonstrate data-intensive services • Telco, Media, Healthcare and Enterprise A 3-year project, European project led by IBM • Started Oct 2010 Now considering features to port to OpenStack Swift… IBM Research - Haifa 9 www.visioncloud.eu © 2012 IBM Corporation

Cloud Data Management
Interface (CDMI): An emerging standard interface for storage cloud RESTful HTTP(s) Interface: Create, Retrieve, Update and Delete objects and containers (along with other abstractions) ►Capabilities: Allow implementation to define which subset it is supports ►CDMI-aware and non-CDMI-aware clients Client issues: HTTP(s) GET, PUT, POST, DELETE CDMI Cloud Requests/Responses can include: Mime-type, data, metadata Implementation responds: HTTP(s) Status Defined by SNIA (Storage Networking Industry Association) and v1.01 in process of ISO standardization April 2009 April 2010 March 2011 April 2011 September Current: Cloud TWG CDMI V1.0 CDMI Submitted 2011 CDMI Work on launched published reference for ISO v1.0.1 CDMI 1.1 implemen- standard errata tation published IBM Research - Haifa 10 © 2012 IBM Corporation
11.
Rich Meta Data
Support for Objects Description • Metadata integral part of objects • Can describe content and how handled • Provide queries over metadata Benefits • Increases the value of object stores as an infrastructure for building value-add applications over the stored data, e.g. for healthcare, telco and media. IBM Research - Haifa 11 © 2012 IBM Corporation
12.
Rich Meta Data
Support for Objects Index and queries for user metadata A catalog maintains for each object in a container a list of MyContainer the attributes and attribute-value pairs Obj 1 • A content-centric query requires a look-up in the catalog Obj 3 Example (schematic) – list all red objects GET /MyContainer/ HTTP/1.1 Obj 2 . . . x-Match-md: x-Attribute=‘color’ x- Value=‘red’ Response (schematic) Attribute Value Object HTTP/1.1 200 OK Content-Type: application/json color red Obj 3 { shape square Obj 2 "children" : [ “Obj 2", shape triangle Obj 1 “Obj 3" ] color blue Obj 1 } color red Obj 2 shape square Obj 3 IBM Research - Haifa 12 © 2012 IBM Corporation
13.
Computational Support via
Storlet Engine Description • “Stored procedures” for a storage cloud • Provide ability to run computations (storlets) safely and securely, close to the data Benefits • Reduce bandwidth, prevent exposure of sensitive data • Enables extending Swift without changing its code • Create customized solutions IBM Research - Haifa 13 © 2012 IBM Corporation
14.
Storlets are the
“stored procedure” of object clouds PUT Pudong Feb 2012 Storlets provide a safe and secure way to execute mimetype = jpeg computations in a storage cloud category = vacation picture • Typically run in a sandbox location = Shanghai Storlets are uploaded as objects Thumbnail Creator • Distinguished from other objects by metadata Object-type = storlet Storlets are triggered by events on objects (e.g., Put object trigger: put/get) and associated metadata attributes mimetype = jpeg category = vacation picture • Synchronous or asynchronous Code: Benefits .... • Locality – avoid network overhead • Security – avoid transferring data outside of cloud • Timeliness Pudong Feb 2012 thumbnail • Automated execution mimetype = jpeg • Stronger provenance category = vacation picture Use cases Location = Shanghai • Transformations on data, e.g., transcoding, computing thumbnails • Extraction/derivation of metadata • Simple computations IBM Research - Haifa 14 © 2012 IBM Corporation
15.
Meta data and
Storlets in action Managing and Serving Content Transcode into additional formats. Metadata indicates formats Telco use case Use metadata to Upload select optimum format MPEG-4 for device/browser Media use case Low-res copy IBM Research - Haifa 15 © 2012 IBM Corporation
16.
Supporting Secure Multi-Tenancy Description
• Provide secure logical isolation between tenants to enable hosting of many tenants over the same shared infrastructure • User of one tenant cannot access storage of another tenant • Security breach in one tenant cannot be leveraged to breach another tenant Benefits • Feature required in order to provide secure public object cloud IBM Research - Haifa 16 © 2012 IBM Corporation
17.
We want to
allow secure lightweight isolation between tenants while allowing complete sharing of physical resources Approach Run time model and security Model • Principle of least privilege: Every sub component should operate using the least set of privileges required for the job completion. Tenant Multi-tenancy and isolation • Build a system with separate tenant privileges. If the system is compromised the damage should be confined to a single User tenant. • There should be a complete isolation of all tenant related information to prevent any cross-tenant leakage. • All data-at-rest should be encrypted with a per tenant key Container Scalability and performance • Security that can scale Object • Limit the performance affecting overheads. IBM Research - Haifa 17 © 2012 IBM Corporation
18.
Secure WAN De-duplication Description
• Phase 1: Support full object deduplication in the storage and over the network. • Phase 2: Add Proof of Ownership (PoW) mechanisms to enable secure WAN deduplication Benefits • Capacity and bandwidth efficiency for applications like Mail and content depots • Security for client use is unique IBM Research - Haifa 18 © 2012 IBM Corporation

Client-side deduplication in
a cloud has a potential for significant savings, capacity and bandwidth but entails security challenges Allows savings both bandwidth and capacity Content is new Content already exists Basic protocol: Client computes a deterministic short hash of the data Client Swift Client Swift Client sends hash value to the cloud server Data Content Data Content Cloud asks for the actual data only if the hash SHA SHA (and data) are unfamiliar 1 1 2fd4e1c6 2fd4e1c6 One problem to address is spoofing uploads Create: object1 Create: object2 Attacker obtains hash of victim’s file Content-id: 2fd4e1c6 Content-id: 2fd4e1c6 Attempts to upload a file, but swaps the hash value with that of the victim’s file. Object w/ content ID 2fd4e1c6 doesn’t exist Object w/ content ID 2fd4e1c6 exists File is now registered to attacker Download file… Special error response Success response Create: object1 Content-id: 2fd4e1c6 Only need to get hold of a very small (not necessarily secret) piece of information Data Content Example: 160 bits to get hold of a 1.5GB object from a popular backup server Create ‘object1’ Success response We have developed a solution called Proofs of Ownership (PoW) A challenge response phase during uploads IBM Research - Haifa 19 © 2012 IBM Corporation
