1 OTM in the Cloud Ryan Haney
2 The Cloud The Cloud is a set of services and technologies that delivers real-time and ondemand computing resources Software as a Service (SaaS) delivers preconfigured applications, usually through web browsers Platform as a Service (PaaS) delivers a solution stack (like LAMP) tailored to certain application types Infrastructure as a Service (IaaS) delivers complete server and network infrastructure on-demand hosted by a cloud provider
3 Cloud Providers Amazon AWS Most popular and largest provider PaaS and IaaS solutions Large number of Cloud datacenters and services Rackspace Offers Windows and Linux Cloud servers Hybrid cloud model allows for half cloud, half physical infrastructures Microsoft Windows Azure Runs Windows and Linux Has IaaS and PaaS offerings Many other providers, including leading commodity hardware manufacturers
4 Benefits to the Cloud Costs No capital expenses, pay as you go Scale on demand Ease of maintenance, simplified infrastructure Agility in responding to business needs Instances dedicated to UAT, new projects, patch/upgrade testing created on demand Scripted deployments for fast server creation and application installation New projects can have server assets in place in hours versus weeks or months
5 Downsides to the Cloud Downtime Risks Amazon AWS major outages April hours, US East August hour, US East June hours, 14 hours, US Audit and East regulatory requirements Major cloud providers have SSAE16/SAS70 reports, and are PCI-DSS Level 1 certified Application expertise High throughput, high performance cloud offerings are not as fast as traditional hardware Cloud server configurations are limited
6 Cloud Offerings Amazon AWS Amazon m1.xlarge 6.5 ECU, 2 cores 17.1GB RAM 1 Gb Network 420GB Storage EC2 Storage Amazon hi1.4xlarge 35 ECU, 8 cores 60.5GB RAM 10 Gb Network 2TB SSD Storage EC2 Storage 1 ECU provides equivalent CPU to Ghz 2007 Xeon
7 Cloud Architecture Amazon EC2 Instance OTM App/Web 01 EC2 Instance Database 01 Internet Elastic Load Balancing EC2 Instance OTM App/Web 02 EBS Volume Security Group Security Group Availability Zone US East 1a
8 Cloud Offerings Rackspace Rackspace Large 4 core CPU 15.8GB RAM 1 Gb Network 620GB Storage
9 Cloud Architecture Rackspace
10 Physical Servers - Commodity Mid-tier DB Intel X Ghz 64GB RAM 1 Gb Network 5.8TB Storage RAID 5, 15k RPM Upper-tier DB Intel E Ghz 96GB RAM 1 Gb Network 6.3TB Storage RAID 5, 10k RPM
11 Physical Servers - Commodity Mid-tier Application Intel E Ghz 16GB RAM 1 Gb Network 900GB Storage RAID 5, 10k RPM Upper-tier Application Intel E Ghz 32GB RAM 1 Gb Network 900GB Storage RAID 5, 15k RPM
12 Physical Architecture
13 Costs - Yearly On Demand $70, $60, $50, $40, $30, Year 1 Year 2 Year 3 $20, $10, $0.00 Mid-tier hardware Upper-tier hardware Amazon AWS Large Amazon AWS High IO Rackspace Large Ongoing costs for hardware include power, colocation, and bandwidth 2 application/web and 1 database configuration
14 Costs AWS Reserved $70, $60, $50, $40, $30, Year 1 Year 2 Year 3 $20, $10, $0.00 Mid-tier hardware Upper-tier hardware Amazon AWS Large Amazon AWS High IO Rackspace Large Ongoing costs for hardware include power, colocation, and bandwidth 2 application/web and 1 database configuration
15 Costs 3 Year TCO On Demand $140, $120, $100, $80, $60, Year 3 Year 2 Year 1 $40, $20, $0.00 Mid-tier hardware Upper-tier hardware Amazon AWS Large Amazon AWS High IO Rackspace Large Ongoing costs for hardware include power, colocation, and bandwidth 2 application/web and 1 database configuration
16 Costs 3 Year TCO with AWS Reserved $120, $100, $80, $60, Year 3 Year 2 Year 1 $40, $20, $0.00 Mid-tier hardware Upper-tier hardware Amazon AWS Large Amazon AWS High IO Rackspace Large Ongoing costs for hardware include power, colocation, and bandwidth 2 application/web and 1 database configuration
17 Benchmarks DaCapo Simulates single threaded loads similar to bulk plans VolanoMark Simulates multi-threaded, high subsystem I/O loads similar to agent processing, also simulates web traffic HammerOra TPCC style Oracle OLTP database benchmark, 70% read 30% write
18 DaCapo Time (Milliseconds) Average Score Rackspace Large Amazon AWS Large Amazon AWS High IO Mid-tier hardware Upper-tier hardware Lower score is better
19 VolanoMark Connections per second Average Score Average Per Core Rackspace Large Amazon AWS Large Amazon AWS High IO Mid-tier hardware Upper-tier hardware Higher score is better
20 HammerOra Transactions per Minute (Higher is better) Amazon AWS Large Amazon AWS High IO Rackspace Large Mid-tier hardware Upper-tier hardware Virtual Users
21 Cost vs Performance - DaCapo Year On Demand 1 Year Reserved Rackspace Large Amazon AWS Large Amazon AWS High IO Mid-tier hardware Upper-tier hardware Higher score is better
22 Cost vs Performance - VolanoMark On Demand AWS Reserved Rackspace Large Amazon AWS Large Amazon AWS High IO Mid-tier hardware Upper-tier hardware Higher score is better
23 Cost vs Performance - HammerOra On Demand AWS Reserved Rackspace Large Amazon AWS Large Amazon AWS High IO Mid-tier hardware Upper-tier hardware Higher score is better
24 Overall Cost vs Performance AWS reserved instances make current Cloud cost/performance exceed hardware in some cases Database performance per dollar spent is higher on hardware Storage I/O is the leading factor Cost vs performance plays to the Cloud s existing strengths horizontally scaled applications RDBMS and other applications that benefit from vertical scale are less cost efficient currently in the cloud
25 Disaster Recovery on AWS Internet Active DNS Elastic Load Balancing Route 53 Hosted Zone Elastic Load Balancing EC2 Instance OTM App/Web 01 Security Group EC2 Instance OTM App/Web 02 EC2 Instance OTM App/Web 01 Security Group EC2 Instance OTM App/Web 02 EC2 Instance Database 01 EC2 Instance Database 01 Mirroring / Replication EBS Volume Security Group EBS Volume Security Group Availability Zone US East 1a Availability Zone US West 1a
26 Hybrid OTM DR with the Cloud
27 OTM Benefits and Usage Development and Test Systems Agility of the cloud without the need for high performance Lower costs if reserved AWS servers are Upgrade used and testing if servers Test are new powered OTM versions off offhours impacting existing development without cycles Disaster Recovery Running versus non-running billing for AWS DR system is potentially lower throughput Replicate databases, do not launch app Training servers Train until needed users on cloud systems to avoid impacting development cycles
28 OTM Benefits and Usage Con t Vendor certification/poc Validate new OTM related products with lower startup costs High Performance Production Cloud performance still lags behind hardware Support Cloud technology is still new, bugs and support difficulties may exist Amazon and Oracle joint support agreement for EC2 applications Amazon RDS and Oracle Future licensing Troubleshooting Opacity Opacity to upstream issues can make troubleshooting OTM performance more difficult
29 Future Cloud Growth AWS prices are reduced 2-3 times per year, on average Amazon High I/O instance is the benchmark for near-future Cloud performance Google has joined the Cloud market with Google Cloud Platform Growth trends through 2010 show a faster decrease in Cloud resource prices than corresponding hardware, excluding storage Future generations of enterprise applications will be tailored to cloud deployments, both public and private
