1 Integrating Network Management for Cloud Computing Services Final Public Oral Exam Peng Sun

2 What is Cloud Computing Deliver applications as services over Internet Run applications in datacenters Lower capital and operational expenses 1

3 Cloud Services are Growing Public cloud for consumer service Amazon Web Services Microsoft Azure 2

4 Cloud Services are Growing Public cloud for consumer service Amazon Web Services Microsoft Azure Enterprises out-source IT service Storage: Box, Analytics: Salesforce, Productivity: Office365, 2

5 Quality of Cloud Service Depends on Network Quality Datacenter ISP App Routing OS Hardware ISP Enterprise Network Servers Network Devices ISP 3

6 Improve Network Quality The old way cannot keep up with the growth of cloud services Deploying more devices with higher bandwidth 4

7 Improve Network Quality The old way cannot keep up with the growth of cloud services Deploying more devices with higher bandwidth The key is proper management of network resources 4

20 Datacenter Breaks Balance Coordination of server & network: More applications are built as multitier distributed systems Intra-datacenter traffic is new majority 8

21 Datacenter Breaks Balance Coordination of server & network: More applications are built as multitier distributed systems Intra-datacenter traffic is new majority Infrastructure evolution speeds up: Network architecture changes (e.g., FatTree) 8

22 Disjoint Mgmt. is Bottleneck Because: Cloud service providers have stakes in all three management areas: Server, infrastructure, traffic 9

23 Disjoint Mgmt. is Bottleneck Because: Cloud service providers have stakes in all three management areas: Server, infrastructure, traffic Great opportunity exists for consolidation Google and Microsoft on SoftWAN 9

24 Yet Another Problem: Low-level Device Interaction Hardware vendors differentiate with specialized devices Network operation: intensively uses vendor-specific APIs heavily depends on experiences 10

25 Cloud Service is Different Much more devices in datacenters than traditional networks Automation is a must 11

26 Cloud Service is Different Much more devices in datacenters than traditional networks Automation is a must Commodity devices instead of specialized hardware Homogeneity is preferred 11

27 Cloud Service is Different Much more devices in datacenters than traditional networks Automation is a must Commodity devices instead of specialized hardware Homogeneity is preferred Lower vendor dependence pays off (MS & Amazon on SoftLB) 11

28 Promising Yet Limited SDN Great way of automating traffic management with high-level programming paradigms Yet literature focus on just traffic 12
