Storage for Different Compute Clouds

Transcription

1 Storage for Different Compute Clouds Session D-203, OpenStorage: Use Cases Joe Arnold CEO, SwiftStack Inc. October

2 Storage for Different Compute Clouds Essential elements of Cloud Different compute cloud environments Different storage options for cloud Focus on Object Storage for unstructured data Use case examples October

3 Essential Elements of IT (including Cloud) Application Compute Network Storage October

4 Applications Applications are changing SaaS, collaboration, social Where they run also changing October

5 Compute Optimized to serve application users Steady state, burst, periodic / scheduled load October

6 Networking Optimized to move data, from storage, to users Steady state, burst, load balance, over distance October

7 Storage Different than compute and networking Data accumulates, much harder to move October

8 Open is the preference for Cloud Avoiding lock-in Platform Data Tools Better visibility into how it works Troubleshooting Documentation & Training October

9 Types of Cloud Storage Public Private Block File Object October

10 Types of cloud storage Traditional Private Storage Public Cloud Object Storage Open Private Cloud Storage Scale Hard Easy Easy Resiliency Good Very Good Very Good Ownership Strong Weak Strong Control High Low High Lock-in Yes Yes No Cost $$$??? $ October

11 Public Cloud Storage Optimized for the compute offered by that vendor Pros Very easy to get started Very scalable Good resiliency Cons Cost at scale Migration when needed Control and custody October

12 When to choose Public Cloud When data is fairly small <100TB When you don t have a datacenter Can have private hosted When testing / proving application If privacy is not a concern October

13 Private Cloud Storage Can be used with any compute environment Pros Cost certainty at scale Strong control and ownership Scalability and resiliency When to choose Anytime privacy / control is a requirement Scale 100TB and beyond For new applications October

14 OpenStack Swift Architecture October

15 Durability ensured by distributed replication checks October

16 Consistency ensured by auditing October

17 Shared nothing architecture The Ring October

18 Seagate Kinetic Ethernet, key/value devices October

19 Storage Node: Current System October

20 Storage Node: Seagate Kinetic October

21 Seagate Kinetic & SwiftStack Resources Seagate Platform Developer Kit: SwiftStack Resources October

22 Region Support October

23 Affinity Writes October

24 How Object Storage is Different October

25 Example: OpenStack Swift Web addressable Everything has URL Content served directly to devices Easy to use Simple, RESTful API and a wide range of client tools % Durability All data replicated 3x Massive concurrency Ideal for many concurrent users Multi-tenant Standard Hardware Huge, flat namespace for all your applications October

26 Private Cloud Use Case - Enterprise SaaS Expense Reporting Receipts from mobile devices Microsoft compute environment Two geographically-distributed data centers to lower latency October 2013

27 Private Cloud Use Case - Infrastructure Largest Cloud at Disney - supporting online gaming & more Citrix Cloud Platform compute environment Product not Project Integration with their Enterprise - LDAP October 2013

28 Other Private Cloud Use Cases Online Gaming Broadcasting Service Provider Cost / Control / Concurrency Amazon environment Millions of users / Massive concurrency Booting 100s of VMs simultaneously High cost and of video archives, sharing limits Microsoft environment 800 events / yr. Tape not on-demand CIFS / NFS interface Off-site disaster recovery Multi-tenant storageas-a-service CA AppLogic environment Regional focus, global footprint Pay-as-you-go capex October

29 What s Next OpenStack Swift 1. Flexible Storage 2. Optimized Storage Platforms 3. Erasure Codes 4. Storage Policies October
