Infrastructure as a Service (IaaS)Infrastructure as a Service (IaaS)Provides multiple "virtualmachines" (VMs) from asingle piece or collectionof hardware (bare metal).VMs can be differentoperating systems(Windows, Linux) runningon same hardware.Average 4 to 1 ratiodepending on applicationof VM. ( 1 CPU core = 4virtual CPUs)Commercial: FOSS:
VMWareOpenStack
Platform as a Service (PaaS)Platform as a Service (PaaS)Provides a platform allowingcustomers to develop, run andmanage web applications.Can run on top of IaaS solutions.Creates "gears" or slices ofcomputing resources.Developers can add "Cartridges" suchas databases and programminglanguages.

Software as a Service (SaaS)Software as a Service (SaaS)SaaS is software licensed on asubscription base and is centrallyhosted by a provider.Also known as on-demandsoftware.Most everyday consumableinternet services are SaaS, suchas e-mail and collaborationsoftware.Microsoft Office365 and AdobeCreative Cloud license anddistribute centrally but youdownload software to computer.
Software StacksSoftware StacksSoftware stacks are
'layers' of software thatwhen combined together
provide a service.
Popular Example: LAMPLinuxApacheTomcat WebserverMySQLPHP Programming Language
Software StacksSoftware StacksPopular and fastest growing stack: MEAN Stack
The Rise of AngularThe Rise of AngularJavaScript web frameworksupported by GoogleAllows creation of SPAs (SinglePage Applications)
Example of SpeedExample of SpeedCreated a Poll Application
Create a new PollCreate one to many questionsOpen for a certain time periodUsers can only answer onceEmail the poll URLMetrics on Poll results
Results:Created a Node / MongoDB Gear in OpenShiftUsed the MEAN StackWrote basic CRUD (create, read update, delete) operationsUsed D3.js library for chartsBack for review with customer in 128 minutes!

Small teams from 1 -3developers can usually staywithin a development branchwithout code merge issues.More than 3 developers on ateam and branches should bebroken down into featuresand merged into adevelopment branch.

It is important to build in timefor test creation into theSprint.Also make sure to create peertests
Developer codes featureDeveloper writes tests forfeaturePeer review featurerequirements and re-runstests or creates new tests
