Automating Performance and Energy Consumption Analysis for Cloud Applications Feifei Chen Swinburne University of Technology Melbourne, Australia Save this template as a new PowerPoint Presentation, giving it the name you require OR copy these templates from Slide Master view into your existing presentation’s Slide Master options If you go to >View > Slide Master you will see this template can be applied in Black, White or Grey background versions (which you will apply as you build or edit your presentation) Close Slide Master view. You can now construct your presentation. In the Slides area, select ‘New Slide’ to add a new slide. To apply a slide style to the new/highlighted slide - in the Slides area, select ‘Layout’ menu, select preferred slide style from the menu (eg. ‘Title and Content’) , select ‘Reset’. If you are updating an existing presentation, existing styles may not automatically update (hence using ‘reset’,) especially if the existing slide has not been produced with a template. Text from imposed text boxes may need to be cut & pasted into new auto-generated template text boxes etc. You should only use one colour template for each presentation (eg. Only black background, or white, or grey – not a combination) The Design uses only 24pt Arial as the font, with 22pt the minimum text size (used at third level). The title page ‘wave’ graphics can be increased in width, but not height. CRICOS Provider: 00111D | TOID: 3059 1

Benefits of Cloud

High CO2 emissions contribution Dark Side of Cloud High CO2 emissions contribution Gartner Report 2007: IT industry contributes 2% of world's total CO2 emissions New York Times 2012: Data centres use about 30 billion watts of electricity per hour worldwide, equivalent to the output of about 30 nuclear power plants

Dark Side of Cloud High Operational Cost U.S. EPA Report 2007: 1.5% of total U.S. power consumption used by data centers which has more than doubled since 2000 and costs $4.5 billion

Green Cloud Computing

Service Level Agreement (SLA)

Understand both system performance and energy consumption pattern A key objective of cloud service providers: Develop solutions to cloud application deployment and management with minimum energy consumption while still guaranteeing performance and other Service Level Agreement (SLA) targets. Performance Service Providers Energy Consumption Understand both system performance and energy consumption pattern Assignment 7 – solution architect – 5 objectives For this – energy efficiency

Outlines Background Problem Analysis Approach Evaluation 10

Understand both system performance and energy consumption pattern: running extensive experiments with heterogeneous parameters/metrics and workloads; collecting appropriate cloud and application energy/performance measurements; performing energy/performance trade-off analysis. 11

JPetStore Deployment Workload 1000 Users 5000 Users

Challenges Manually performing the tasks is tedious and time- consuming Cloud system performance is related to Architecture Workload An automated performance and energy consumption evaluation framework is imperative The framework should be able to accommodate different cloud system architectures and adopt different application workloads during load tests and the trade-off evaluation process 13

Experiment Setup Energy and performance profiling framework VM configuration   Virtual Machine Number of Cores RAM Hard Disk Small 1 2GB 80GB Medium 2 4GB Large 3 6GB XLarge 4 8GB

Energy Consumption and Throughput Experiment Results Test set 1: Keep the resource allocation strategy constant while changing workload System Configurations: 1 Large VM (3CPUs and 6GB RAM) Workload: user workload 50~200 Energy Consumption and Throughput Deploy MJPetStore on one VM with 3 CPUs and 6GB RAM. The initial number of users was set to 10. We then increased the concurrent requests number of each user from 50 to 200 in steps of 50.

Energy Consumption and Throughput Experiment Results Test set 2: Keep the workload constant while changing the resource allocation strategy System Configuration: 1Large: Deploy three types of tasks on the 1 VM. 3Small(D): Deploy three types of tasks on different VMs. 3Small(S): Deploy three types of tasks on the same VM with workloads evenly distributed across all VMs. Workload: user request 100.
