Patterns and practices for building enterprise-scale HTML5 apps
Patterns and practices for building enterprise-scale HTML5 appsPhil Leggetter Developing large apps is difficult. Ensuring that code is consistent, maintainable, testable and has an architecture that enables change is essential. As is ensuring that multiple developers – across multiple teams – can efficiently contribute to the same application. When it comes to large server-focused apps, solutions to some of these challenges have been tried and tested. But, how do you achieve this when building HTML5 single-page apps?
In this session, Phil will cover the experiences his team have had when building HTML5 apps consisting of more than 250k lines of JavaScript (plus HTML templates, CSS, image, config etc) that are contributed to by multiple teams across multiple companies. He will highlight signs to watch out for as your HTML5 SPA grows, and a set of patterns and practices that help you avoid problems. He will also explain the simple yet powerful application architecture that their HTML5 apps have that is core to ensuring they scale.
Finally, Phil will demonstrate how tooling can be used to support these patterns and practices, and enable a productive developer workflow where the first line of code is feature code, features can be developed and tested in isolation, code conflicts are avoided by grouping assets by feature, and features are composed into apps.

From Zero to Serverless (CoderCruise 2018)Chad Green Chad Green gives a presentation on serverless computing. He discusses the evolution from on-premises to infrastructure as a service (IaaS) to platform as a service (PaaS) to serverless. Serverless applications depend on cloud services to manage server-side logic and state using event-triggered functions. Chad then covers Azure Functions as a serverless option, including features, triggers/bindings, development tools, and best practices like avoiding long functions and writing stateless code.
From Zero to Serverless (DogFoodCon 2018)
From Zero to Serverless (DogFoodCon 2018)Chad Green So many times our customers need a simple routine that can be executed on a routine basis but the solution doesn’t need to be an elaborate solution without going the trouble of setting servers and other infrastructure. Serverless computer is the abstraction of servers, infrastructure, and operating systems and make getting solutions to your customer’s needs much quicker and cheaper. During this session we will look at how Azure Functions will enable you to run code on-demand without having to explicitly provision or manage infrastructure.

Devops - why, what and how?
Devops - why, what and how?Malinda Kapuruge This document provides an overview of DevOps, including:
1) It discusses Garry, a product owner whose team had slow and manual software delivery processes until discovering DevOps.
2) DevOps is defined as a culture change involving shared responsibility between development and operations teams to deliver software rapidly through practices like continuous integration, delivery, infrastructure as code, and monitoring.
3) The benefits of DevOps are outlined as faster and more frequent software delivery, improved quality, security, and compliance through automation and visibility across the software lifecycle.
4) Examples of DevOps in action include deploying a web application directly from a development machine versus through an automated build and test process on a separate build box.
Single Source of Truth for Network Automation
Single Source of Truth for Network AutomationAndy Davidson The document discusses the journey of network automation from simple reporting to fully integrated automated businesses. It emphasizes establishing a single source of truth for network data through a data model and storing data in a centralized database. This enables templated configuration generation and automation of network and business processes through APIs, workers, and tools that interface with the centralized data. Proper software architecture like separating customer and infrastructure data, using APIs, workers and templating promotes flexibility, testability and the ability to configure networks and businesses rather than individual devices.

Cloud-native Data: Every Microservice Needs a Cache
Cloud-native Data: Every Microservice Needs a Cachecornelia davis Presented at the Pivotal Toronto Users Group, March 2017
Cloud-native applications form the foundation for modern, cloud-scale digital solutions, and the patterns and practices for cloud-native at the app tier are becoming widely understood – statelessness, service discovery, circuit breakers and more. But little has changed in the data tier. Our modern apps are often connected to monolithic shared databases that have monolithic practices wrapped around them. As a result, the autonomy promised by moving to a microservices application architecture is compromised.
With lessons from the application tier to guide us, the industry is now figuring out what the cloud-native architectural patterns are at the data tier. Join us to explore some of these with Cornelia Davis, a five year Cloud Foundry veteran who is now focused on cloud-native data. As it happens, every microservice needs a cache and this evening will drill deep on that topic. She’ll cover a variety of caching patterns and use cases, and demonstrate how their use helps preserve the autonomy that is driving agile software delivery practices today.

DevOps Friendly Doc Publishing for APIs & Microservices
DevOps Friendly Doc Publishing for APIs & MicroservicesSonatype Mandy Whaley, CISCO
Microservices create an explosion of internal and external APIs. These APIs need great docs. Many organizations end up with a jungle of wiki pages, swagger docs and api consoles, and maybe just a few secret documents trapped in chat room somewhere… Keeping docs updated and in sync with code can be a challenge.
We’ve been working on a project at Cisco DevNet to help solve this problem for engineering teams across Cisco. The goal is to create a forward looking developer and API doc publishing pipeline that:
Has a developer friendly editing flow
Accepts many API spec formats (Swagger, RAML, etc)
Supports long form documentation in markdown
Is CI/CD pipeline friendly so that code and docs stay in sync
Flexible enough to be used by a wide scope of teams and technologies
We have many interesting lessons learned about tooling and how to solve documentation challenges for internal and external facing APIs. We have found that solving this doc publishing flow is a key component of a building modern infrastructure. This is most definitely a culture + tech + ops + dev story, we look forward to sharing with the DevOps Days community.
QCon 2015 - Microservices Track Notes 
QCon 2015 - Microservices Track Notes Abdul Basit Munda These are my summarized notes from all the microservices session I attended at QCon 2015. These sessions had tons of learning around how to scale microservices and avoid common pitfalls
The business case for contributing code
The business case for contributing codeZivtech, LLC In the Drupal community we tend to talk about committing code to our public spaces (drupal.org, but also github) in terms of "contributing" and "contributions", and while much of it can be seen in that light, there are actually very strong business reasons for publishing your code and/or attempting to get your code changes committed to the open source project that you are working on.
We will be looking at several documents from the U.S. Military detailing their recommendations for contracting Open Source Software services, and will use those as a jumping off point to discuss the many benefits of contributing code. Some of the business reasons for public publishing we'll explore will include:
* The power of peer review. With enough eyes, all bugs are shallow, and with only a few eyes the stupidity knows no depths!
* Fork you! The costs associated with "hacking" both Drupal core and contrib modules and base themes.
* Take my code, please! Cost savings from committing patches.
* Professionals publish or perish. Using code commits as marketing towards clients or potential hires.
* It's so easy, even a child(ish person) could do it! How you can easily integrate patching into your development workflow.
This session will also include a walk through of how Zivtech handles code review, patches, and deployment processes and you will hopefully walk away convinced that all of your in-house and out-sourced developers should be publicly committing their work.

How Valletta helped healthcare SaaS to transform QA and compliance to grow wi...Egor Kaleynik This case study explores how we partnered with a mid-sized U.S. healthcare SaaS provider to help them scale from a successful pilot phase to supporting over 10,000 users—while meeting strict HIPAA compliance requirements.
Faced with slow, manual testing cycles, frequent regression bugs, and looming audit risks, their growth was at risk. Their existing QA processes couldn’t keep up with the complexity of real-time biometric data handling, and earlier automation attempts had failed due to unreliable tools and fragmented workflows.
We stepped in to deliver a full QA and DevOps transformation. Our team replaced their fragile legacy tests with Testim’s self-healing automation, integrated Postman and OWASP ZAP into Jenkins pipelines for continuous API and security validation, and leveraged AWS Device Farm for real-device, region-specific compliance testing. Custom deployment scripts gave them control over rollouts without relying on heavy CI/CD infrastructure.
The result? Test cycle times were reduced from 3 days to just 8 hours, regression bugs dropped by 40%, and they passed their first HIPAA audit without issue—unlocking faster contract signings and enabling them to expand confidently. More than just a technical upgrade, this project embedded compliance into every phase of development, proving that SaaS providers in regulated industries can scale fast and stay secure.
Who Watches the Watchmen (SciFiDevCon 2025)
Who Watches the Watchmen (SciFiDevCon 2025)Allon Mureinik Tests, especially unit tests, are the developers’ superheroes. They allow us to mess around with our code and keep us safe.
We often trust them with the safety of our codebase, but how do we know that we should? How do we know that this trust is well-deserved?
Enter mutation testing – by intentionally injecting harmful mutations into our code and seeing if they are caught by the tests, we can evaluate the quality of the safety net they provide. By watching the watchmen, we can make sure our tests really protect us, and we aren’t just green-washing our IDEs to a false sense of security.

Proactive Vulnerability Detection in Source Code Using Graph Neural Networks:...
Proactive Vulnerability Detection in Source Code Using Graph Neural Networks:...Ranjan Baisak As software complexity grows, traditional static analysis tools struggle to detect vulnerabilities with both precision and context—often triggering high false positive rates and developer fatigue. This article explores how Graph Neural Networks (GNNs), when applied to source code representations like Abstract Syntax Trees (ASTs), Control Flow Graphs (CFGs), and Data Flow Graphs (DFGs), can revolutionize vulnerability detection. We break down how GNNs model code semantics more effectively than flat token sequences, and how techniques like attention mechanisms, hybrid graph construction, and feedback loops significantly reduce false positives. With insights from real-world datasets and recent research, this guide shows how to build more reliable, proactive, and interpretable vulnerability detection systems using GNNs.
