Agile Cloud Architecture for TDM and Architects

Transcription

1 Agile Cloud Architecture for TDM and Architects Lawrence Tse Director, Professional Services Chief Architect Falcon Consulting (HK) Limited

2 Hybrid Cloud Architecture Ecology Most customer leverages virtualization only Public cloud infrastructure does not structurally integrated with on premise infrastructure Lack of consistent management instrumentation Supportability is not properly emphasized Product focused Lack of architecture and service delivery awareness

3 Agile Datacenter Architecture Challenges Agile Compute & Disaster Recovery Agile Fabric: Networking Agile Fabric: Storage

4 Agile Fabric Design: Storage

5 A Storage Strategy Avoid Storage Centricity Storage should facilitate, not to restrict Avoid over investment SAN is not the only or the best way out Pooled storage doesn t mean new storage Accept mixture of technologies and SLA Doors always open for other vendors

6 Employ Software-defined Storage Concept Reconciliation of existing resources Allocate and deallocate on demand Classification by performance and SLA Properly leverage dynamic tiering Deployment to storage class instead of absolute location

7 Software Empowered Storage Feature Scenarios Storage Feature Challenges Multi-pathing and dedicated storage channel Static data encryption Data channel encryption Archive storage deduplication Offsite media for compliance Storage replication and failover Software Empowered Solutions Data path aggregation, datacenter bridging, dynamic traffic prioritization Storage layer volume encryption, OS layer volume encryption, vtpm iscsi over IPSec, SMB Direct Software VTL, software disk volume deduplication Software VTL, software volume replication Software volume replication, hypervisor level replication

8 Agile Fabric Design: Networking

9 Cloud and Networking VM Networks Production DMZ Staging DMZ Development DMZ Cloud technical design starts with networking Production Internal Zone Staging Internal Zone Development Internal Zone Avoid networking direct P2V Cloud networking design = complete networking conceptual reform Think logically instead of physically Production DMZ Production Internal Zone Staging DMZ Staging Internal Zone Logical Networks Development DMZ Development Internal Zone Physical Layer Site 1 Site 2 Site 3

10 SDN Concept and Rationale Easy & rapid network provisioning Unified, overlaid network address space across Flexible datacenter/cloud network extension VLAN free isolation Multi-tenancy address space overlapping Eliminate networking hardware Facilitate hardware resources pooling

11 Network Virtualization Concept Host 1 NV Provider Traffic Host 2

12 Agile Fabric Design: Compute & Disaster Recovery

13 Increasing DR Demands with Technology Revolution L2 Tunneling Software Replication x Tape Backup & Recovery SAN Replication Boot from SAN Converged Networking Network Virtualization Year

14 Ecology & Technology Landscape Current Situations Most customer still thinking of SAN or software replication Some customer still looking for L2 tunneling Some customer still using tape/vtl backup/recovery Technology Challenges Expensive Vendor lock-on Limited expandability Complex/manual failover & failback Slow response to incident

15 Cutting Edge, Matured DR Technology Converged Networking RDMA/SMB Direct iscsi 10Gbps, 40Gbps, 56Gbps Ethernet/InfiniBand Datacenter bridging (DCB) Network virtualization Hypervisor level replication Physical to VM replication

16 Reference Architecture Simple Single Site

17 Reference Architecture Multiple Sites

18 Reference Architecture Multiple Sites with Unified Address Space

19 Key Takeaways Cloud infrastructure architecture is somewhat different than physical server infrastructure Cloud flexibility is determined by architecture awareness Architecture procedure: Business requirement fabric design service offering design Typical cloud service offerings: Compute fabric, storage fabric, network fabric, VM templates, distributed applications, network services, etc.
