1 Virtualization Technologies How to Supercharge your Agile Development Team Matthew G. Duvall, PMP July 14, 2015

2 About Me Graduated as Accountant from Radford University This new thing called "Interconnected Networks" hit the scene (aka Internet) Masters in Information Technology from Stevenson University Employed at UMMS in Finance, then transitioned to IT Professional in 2001

3 Agenda Brief History of Computing What is the cloud? Cloud Technologies: OpenStack OpenShift Software Stacks Development Methodologies Managing Agile Development Teams Future Trends

4 Brief History of Computing... too far back

5 History - ENIAC 1946 Source: Wikipedia

6 Main Frames Central Processing Processing "Dumb" Terminal

7 PC Revolution Central Processing Processing Computer Terminal

8 Interconnected Networks "The Internet" The explosive growth of the internet has connected the computing power of many devices across the globe.

9 Increase in Computing Power versus 1997 IBM Deep Blue 2015 Samsung Galaxy S6

10 Increase in Computing Power = 1 Deep Blue = GFLOPs Exynos GPU = 302 GFLOPs

11 Cloud Computing Text Cloud Resources Processing Processing is moving into the "Cloud" Computing Device

12 What is the cloud? Short Answer: "Someone else's computer."

17 Categories of Cloud Services

18 Infrastructure as a Service (IaaS) Provides multiple "virtual machines" (VMs) from a single piece or collection of hardware (bare metal). VMs can be different operating systems (Windows, Linux) running on same hardware. Average 4 to 1 ratio depending on application of VM. ( 1 CPU core = 4 virtual CPUs) Commercial: VMWare FOSS: OpenStack

19 Platform as a Service (PaaS) Provides a platform allowing customers to develop, run and manage web applications. Can run on top of IaaS solutions. Creates "gears" or slices of computing resources. Developers can add "Cartridges" such as databases and programming languages. OpenShift

20 Platform as a Service (PaaS)

21 Software as a Service (SaaS) SaaS is software licensed on a subscription base and is centrally hosted by a provider. Also known as on-demand software. Most everyday consumable internet services are SaaS, such as and collaboration software. Microsoft Office365 and Adobe Creative Cloud license and distribute centrally but you download software to computer.

22 Software Stacks Software stacks are 'layers' of software that when combined together provide a service. Popular Example: LAMP Linux ApacheTomcat Webserver MySQL PHP Programming Language

23 Software Stacks Popular and fastest growing stack: MEAN Stack

24 The Rise of Angular JavaScript web framework supported by Google Allows creation of SPAs (Single Page Applications)

25 Results: Example of Speed Created a Poll Application Create a new Poll Create one to many questions Open for a certain time period Users can only answer once the poll URL Metrics on Poll results Created a Node / MongoDB Gear in OpenShift Used the MEAN Stack Wrote basic CRUD (create, read update, delete) operations Used D3.js library for charts Back for review with customer in 128 minutes!

26 Development Methodologies

27 Agile Development Product Planning derived from backlog of approved features Sprints range from 2-4 weeks max Stable 'production ready' product at the end of sprint Also helps to have an Agile customer!

28 A winning combination! + + = Happy Customer

29 Managing Agile Teams Start with an "Agile Customer", explain the benefits of iterative development. Use some type of 'ticket management' tool to organize Sprints: Trello GitHub Atlassian JIRA image: eremedia.com "Office Space"

30 Managing Agile Teams Set team rules and procedures, such as: code structure branching methodology checkin frequency image: eremedia.com "Office Space"

31 Git Branching Method Small teams from 1-3 developers can usually stay within a development branch without code merge issues. More than 3 developers on a team and branches should be broken down into features and merged into a development branch.

32 Peer Testing and Verification It is important to build in time for test creation into the Sprint. Also make sure to create peer tests Angular Testing: Karma - automatically run tests Jasmine - end to end testing Developer codes feature Developer writes tests for feature Peer review feature requirements and re-runs tests or creates new tests image: eremedia.com "Office Space"

33 Future Trends Docker is a 'shipping container' system for code. Web Components: Polymer Project Angular 2.0 by Google
