Developer Tools and Workflows

A talk about developer tools and workflows. Software development concepts such as QA, DevOps, security, performance, and more, will be introduced. Common developer tools and options will be discussed, followed by workflows built around the Software Development Life Cycle.

The talk will wrap-up with a few demonstrations to show to the power of pulling all of this knowledge together into a reliable and trusted system to continuously deliver quality software.

Regardless of the languages and frameworks you may use, this talk will address issues we all face as developers.

First presented at CharDUG (Charlotte Drupal User Group)

7. 7 Concepts
8. 8 What’s Agile software development? Agile software development describes a set of principles for software development under which requirements and solutions evolve through the collaborative effort of self-organizing cross-functional teams. It advocates adaptive planning, evolutionary development, early delivery, and continuous improvement, and it encourages rapid and flexible response to change. https://en.wikipedia.org/wiki/Agile_software_developmen t Concepts
9. 9 What’s DevOps? DevOps (a clipped compound of development and operations) is a culture, movement or practice that emphasizes the collaboration and communication of both software developers and other information-technology (IT) professionals while automating the process of software delivery and infrastructure changes. https://en.wikipedia.org/wiki/DevOp s Concepts
10. 10 Concepts
11. 11 What’s QA? QA encompasses the entire software development process, which includes processes such as requirements definition, software design, coding, source code control, code reviews, software configuration management, testing, release management, and product integration. SQA is organized into goals, commitments, abilities, activities, measurements, and verifications. https://en.wikipedia.org/wiki/Software_quality_assurance Concepts
12. 12 QA is more than finding bugs • Accessibility • Load testing • Performance • Security Concepts
13. 13 What’s web accessibility? Web accessibility refers to the inclusive practice of removing barriers that prevent interaction with, or access to websites, by people with disabilities. When sites are correctly designed, developed and edited, all users have equal access to information and functionality. https://en.wikipedia.org/wiki/Web_accessibility Concepts
14. 14 U.S. Statistics • Population of U.S. - 303 million people • 57 million or 19% have a disability • 38 million or 12.5% have a severe disability Concepts
15. 15 What’s computer performance? Computer performance is the amount of work accomplished by a computer system. Depending on the context, high computer performance may involve one or more of the following: • Short response time for a given piece of work • High throughput (rate of processing work) • Low utilization of computing resource(s) • High availability of the computing system or application https://en.wikipedia.org/wiki/Computer_performance Concepts • Fast (or highly compact) data compression and decompression • High bandwidth • Short data transmission time
16. 16 Why performance matters • Faster sites lead to increased user engagement • Faster sites lead to increased user retention • Faster sites lead to increased conversions • Faster sites require less resources Concepts
17. 17 The CIA Information Security Triad Confidentiality, integrity and availability. For any information system to serve its purpose, the information must be available when it is needed. This means that the computing systems used to store and process the information, the security controls used to protect it, and the communication channels used to access it must be functioning correctly. High availability systems aim to remain available at all times, preventing service disruptions due to power outages, hardware failures, and system upgrades. https://en.wikipedia.org/wiki/Information_security#Key_concepts Concepts

31. 3 Workflows
32. 32 Software Development Life Cycle The SDLC isn't a methodology per se, but rather a description of the phases in the life cycle of a software application. These phases (broadly speaking) are, investigation, analysis, design, build, test, implement, and maintenance and support. https://en.wikipedia.org/wiki/Systems_development_life_cycle Workflows
33. 33 Software development process Workflows • Meet with Stakeholders • Owner Review and Approval • Analyze Requirements • Review & Prioritize Backlog • Estimate • Groom Tickets • Deploy Code Release • Create Feature Branches • Organize Next Sprint • Automated Testing • Code Review • QA on Staging / UAT • Submit PR for Completed Work SPRINT INTERVAL Site Deployment Drupal Install Profile Epics & User Stories
