3. Agenda A Little History
4. Agenda A Little History Getting Our Bearings At PMMC
5. Agenda A Little History Getting Our Bearings At PMMC Agile CI, CD and CD NoSQL Containers Cloud
6. Agenda A Little History Getting Our Bearings At PMMC Agile CI, CD and CD NoSQL Containers Parting Words Cloud
7. A Little History I PROMISE TO KEEP IT SHORT
8. Early 1990’s
9. Late 1990’s JSP ASP COBOL Java Oracle Visual Basic SQL Server DB2 JavaScript CSS HTML
10. JSP ASP.NET COBOL Java Oracle .NET SQL Server DB2 JavaScript CSS HTML Early 2000’s
11. Late 2000’s ASP.NET JSP ASP.NET MVC PHP Java Oracle .NET SQL Server JavaScript CSS HTML Ruby on Rails MySQL jQuery
12. Today WCF ASP.NET WebAPI ASP.NET JSP ASP.NET MVC PHP Java Oracle .NET SQL Server JavaScript CSS HTML Ruby on Rails MySQL jQuery MongoDB NodeJS Express KnockOut Angular Durandal Handlebars Aurelia Ember React SASS/SCSS Meteor RavenDB Underscore Lodash
13. A Little About My Work at PMMC WHERE WE WERE AND WHERE WE WANT TO GO.
14. Survey Results (Part 1/3)
15. Survey Results (Part 2/3)
16. Survey Results (Part 3/3)
17. #1 Agile Methodology SOME SAY THIS WILL BE SYNONYMOUS WITH SOFTWARE DEVELOPMENT IN THE FUTURE
18. Waterfall Requirements Analysis Design Development Testing Acceptance
19. http://agilemanifesto.org/
20. Notable Agile Variants LEAN - 1990 • Kaizen – continuous improvement • Kanban boards Extreme Programming (XP) – 1999 • Refactoring • Pair Programming • Small Releases • Testing • Continuous Builds Scrum - 2001 • Borrowed from LEAN and XP • Formalized the process with Stand-ups
21. Agile – Scrum Variant 2-4 week sprint Build Product Backlog Determine sprint backlog Analysis Development Testing Acceptance Design Release Daily Stand-ups Retro- spectives Stake- holder Demo
22. Agile – User Story Considerations • Business value • Development effort • Complexity • Known unknowns
23. Agile – Observation People are bad at estimating, but are good at comparing.
24. Agile – Story Priority Example 7 bv / 1 sp = 7 7 bv / 144 sp = 0.049 58 bv / 12 sp = 4.83 Business Value / Story Points (aka Development Effort) = Story Priority
25. #2 NoSQL Databases REMOVES A LOT OF FRICTION POINTS DURING DEVELOPMENT AND PROVIDES MORE FLEXIBILITY
26. What is a NoSQL Database?
27. What is a NoSQL Database? Access SQL Server Oracle Ingress Postgress MySQL DocumentDB CouchDB MongoDB Hadoop RavenDB Graph Databases Document Databases Object Databases Neo4j ObjectDB Key-Value Databases Redis RDBMS
28. Customer Invoices – RDBMS Style
29. Customer Invoices – Mongo Style
30. Benefits • Easy to refactor • Performant • Horizontal scalability by design • Reduced complexity • No DBA required • No need for Object Relationship Mappers (ORM) • Data is more readable "Creative Commons Fireworks" by nuic is licensed under CC BY 2.0
31. When would I prefer a RDBMS over a document database?
32. #3 CI, CD and the other CD IF SOMETHING IS HARD AND ERROR-PRONE, DO IT MORE OFTEN
33. Continuous Integration The practice of compiling code found within a repository frequently.
34. Continuous Deployment The practice of deploying a compiled solution in its entirety to a host or set of hosts, typically to be tested by an automated testing framework.
35. Continuous Delivery The practice of deploying a compiled solution in its entirety to production servers.
36. Automated Testing Let’s let the computers run tests instead of humans. Computers are more thorough, more reliable and lot quicker.
37. #4 Containers REDUCES DEVELOPMENT FRICTION AND IMPROVES HARDWARE UTILIZATION
38. Containerization The abstraction of software packages from the operating system in such a way that the software packages are logically separated from each other and the operating system.
39. “Classic” Multiple Servers CMS Mail Server Source Control Web Server RDBMS Document Database Hardware OS OS OS Hardware Hardware
40. “Classic” Resource Utilization 3 machines 1-3% CPU utilization 1GB RAM
41. Server Usage with Virtualization Virtualization Software Hardware OS Mail Server Source Control web server RDBMS OS OS OS CMS Document Database
42. Virtualization Resource Utilization 1 machine 4-12% CPU utilization 4GB RAM
43. Server Usage with Containers SharePoint Exchange TFS IIS SQL Server Mongo Containerization Software Hardware OS
44. Container-based Resource Utilization 1 machine 1-3% CPU utilization 1GB RAM
45. Side-by-side Comparison Container based 1 machine 1-3% CPU utilization 1GB RAM VM based 1 machine 4-12% CPU utilization 4GB RAM “Classic” 3 machines 1-3% CPU utilization 1GB RAM
46. Other Benefits
47. Other Benefits 1. Spin up times are seconds, not minutes
48. Other Benefits 1. Spin up times are seconds, not minutes 2. Easier onboarding of new developers
49. Other Benefits 1. Spin up times are seconds, not minutes 2. Easier onboarding of new developers 3. Can more easily develop on local containers that match production exactly
50. Other Benefits 1. Spin up times are seconds, not minutes 2. Easier onboarding of new developers 3. Can more easily develop on local containers that match production exactly 4. No more “It works on my machine”
51. Other Benefits 1. Spin up times are seconds, not minutes 2. Easier onboarding of new developers 3. Can more easily develop on local containers that match production exactly 4. No more “It works on my machine” 5. Container removal is a total removal
52. #5 Cloud MORE THAN JUST MARKETING HYPE … SO MUCH MORE.
53. What is the Cloud? 1. Pay for what you use. 2. Self-serve.
54. Types of Cloud Services SaaS – Software as a service
55. Types of Cloud Services SaaS – Software as a service IaaS - Infrastructure as a service
56. Types of Cloud Services SaaS – Software as a service IaaS - Infrastructure as a service PaaS - Platform as a service
57. Types of Cloud Services SaaS – Software as a service IaaS - Infrastructure as a service PaaS - Platform as a service CaaS - Container as a service
58. Ways we Leverage Cloud at PMMC Team Services – PaaS Agile Process Management Source Code Control CI, CD Release Management Azure App Service and API Service - PaaS supporting 3 environments Dev/Test environment – IaaS Can manage startup and shutdown times Allows developers to spin up servers as needed Windows 2012 RS Server VM with Mongo – IaaS
59. Parting Words .
60. Trite Aphorisms Stay Curious! Apply yourself! Don’t get comfortable.
61. Less-Trite Aphorisms With Some Teeth Your first job sets the tone for the rest of your career.
62. Less-Trite Aphorisms With Some Teeth Your first job sets the tone for the rest of your career. Master something you are interested in and get a project doing that. Rinse and repeat.
63. Less-Trite Aphorisms With Some Teeth Your first job sets the tone for the rest of your career. Master something you are interested in and get a project doing that. Rinse and repeat. Embrace contracting or consulting. Job security is based more on your technical skills and people skills than seniority.
64. Less-Trite Aphorisms With Some Teeth Your first job sets the tone for the rest of your career. Master something you are interested in and get a project doing that. Rinse and repeat. Embrace contracting or consulting. Job security is based more on your technical skills and people skills than seniority. Read, listen to podcasts and find mentors.
