Hi – I’m Steve


Welcome to the cloud !


This is great, I think


My goal is to tell you what I think


Clouds are great


Clouds are great – but can get you in trouble


Clouds are actually more difficult/complex than you think


So let’s get started talking about clouds


What is the cloud ?


We are talking about IaaS / Infrastructure


This is about how you Design, Build & Deploy on IaaS


Why the cloud ?


Cheap !


No up-front capital – Pay as you go


Easy to start – Click and compute !


All true, but . . .


Not that important


It’s important to accountants – that’s not us


So what is important – to US ?


#1 – Flexibility – Do what we want, when we want, how we want


#2 - Dynamic – Handle changing needs over time


#3 - Service-Oriented Thinking


#4 - That Scales – Small, big, bigger, huge . . .


Scales, but not in the way you think


Sometimes each service is the same


Sometimes they are not the same


Cloud Design – Think Layers


A key opportunity is Service Architectures – Separate functions


But don’t separate too much – No tiny VMs per function


Cloud Design – Think Services


Cloud Design – Think Scale – HORIZONTAL


Cloud Design – Think Scale – Many Small vs. Few Big


Clouds have limits, too


Common Cloud Layers


Load Balancer


Load Balancers

AWS ELB


Load Balancers – SSL, TCP, Monitoring, Features


Web Layer


Web – Statics & Proxy for App


Web – Statics & Sharing or S3 ?

OR


Application / Code Layer


Application / Code Layer – Memory vs. CPU


Application / Code Layer – Memory vs. CPU

Out of RAM - Swap

Out of CPU- Thrash


Database Layer


Database Layer – Never enough I/O – RAM is helpful


Database Layer – PIOPS & SSD help


Database Layer – PIOPS & SSD – More IOPS !


Database Layer – RDS (Relational DB Service)


Database Layer – RDS – Limitations


More cloud layers – Cache


More cloud layers – Search


More cloud layers – Search – I/O Again (& RAM)


Unusual Cloud Layers - Queue


Unusual Cloud Layers - Unusual


Special Clouds Issues/Worries


Dependencies


Everything runs at speed of slowest service


Where are the dependencies ?


Big fragile machine


Resource Limits – Hitting the wall


Dynamic Cost – More than you think . . .


Deploying on the Cloud – Often & Easily


Deploying on the Cloud – DevOps & Push Systems are your friend


Mix of Deployment Levels

OS & Config

Services & Config

Code & Config


Deploying on the Cloud – Think Clones


But careful of Cloud interaction & orchestration


Things don’t always go well – Coordinate & Signal


Change / improve quickly


And be flexible


That’s the Cloud – Good Luck !
