Our Public Cloud Today
• From 11 datacenters worldwide
India, USA, Canada, UK and Belgium
• Nearly 110,000 virtual machines across 8,000+
customers
Approximately 60,000 CPU cores, ~1,400 servers
Close to 730TB of memory
• ~400PB of fast, reliable and backed up storage
Growing at 3PB per month
Nearly 2.2 billion IOPS of consistent performance
• 99.995% uptime guarantee
• 99.99999999% data durability guarantee
Goals we had to hit
• Cost Goals to customer
• Rs. 1,000 p.m. for a server with 2 vCPUs + 4GB RAM
Including failover/HA, clustering, live migration
99.995% uptime
• Rs. 3 per GB per month for “unbreakable storage”
7,500 IOPS per TB
Clustered, continuously backed up
99.99999999% durability
• Complete provisioning automation – allow customer to create a VM in less than 90 seconds (start to finish)
• 30 day planning cycles
• Tolerate failures, automate management
Technology Enablers
• More cores on the CPU
2008 – 8 to 16 cores
2013 – 32 to 64 cores
• More cores meant more VM density and moving functions done via ASICs (e.g. storage controllers) into software executed by the CPU
• Flash costs - $10 per GB to $1.5 per GB
100x-200x faster than disks
• Low cost 10GbE copper networking
Inter server bandwidth is a non-issue
No need for expensive SAN switches
How did we hit the cost
goals
• Built our own technology
Aggressively used open sourced
Contributed all our IP to the open source community, except for operational control systems
• 80% of the cost is storage and poor CPU utilization due to I/O waits
• Storage – built our own storage technology
Using existing approaches would have cost us 10x more
Merged primary and backup storage
Eliminated storage switching
• Massive VM density per server – 60 to 80 server class VMs – use deduped/compressed tier 1 flash to drive
massive I/O speeds (100,000 IOPS per physical server)

Single Pane of Glass
Single pane of glass to manage VMs, compute, storage and networking
Storage Technology
• Software driven storage controller on each server
Clustered together for reliability
Enables a scale out design
Massive performance
• Speed and Density – server attached flash
91% of the I/O is flash – 100,000 IOPS per server
Dedup/Compression increases flash capacity by 3x
• Erasure Coded multi-node disk storage
1,000x more reliable than RAID5 + 3-way replication
Only requires 1.8x space compared almost 3.6x
Add storage as needed

Benefits of clouds
• IT infrastructure available like electricity
90 seconds to provision a server v/s 90 days
2 days to expand storage v/s 2 quarters
• OS, database, application platform freedom
Provision VMs with the appropriate technology stack for the application, no platform lock-in
• Our estimate is that 70% of cloud based
applications use FOSS platforms (LAMP, Ruby, Node.js, MongoDB)
• Return to custom software
Software represents a business process that is a source of competitive advantage
Accelerates development to deployment cycles - Devops
Our work with Cisco
• On-Premise Amazon Web Services like cloud
• Cisco UCS hardware, Convergd SDS and cloud technology
• Single Appliance – <Rs. 10 lacs for a full cloud in a box
• Hyperconverged Cluster - <Rs. 25 lacs for a full cluster
• On-premise pay as you go cloud
Rs. 1,000 for a 2 vCPU + 4GB RAM virtual machine
Rs. 2 per GB per month for clustered, backed up storage at a speed of 7,500 IOPS per TB
• Cisco certified hosted private cloud out of Tier 4 datacenter in Mumbai
Cloud at IIT Bombay
• First clustered cloud deployed by us at IIT Bombay
• Runs IIT-BombayX which is a MooC created by IIT Bombay
• End to end open source – Convergd, OpenEdX, MySQL, MongoDB, RabbitMQ
• Built to scale to 10mn students
• 80% lower in cost than the lowest cost public cloud
• Deployed in September 2014, not a single instance of downtime
