Team collaboration in the Cloud allows developers to work together on projects hosted on Heroku. Heroku is a platform as a service that manages the infrastructure and servers, so developers can focus on coding. Key features of Heroku include automatic scaling of applications, unified logging across all processes, and easy deployment through Git pushes. Heroku also offers add-ons for additional services like databases and monitoring that further enhance collaboration.
12 Factor, or Cloud Native Apps – What EXACTLY Does that Mean for Spring Deve...cornelia davis
Talk given at SpringOne 2015
The third platform, characterized by a fluid infrastructure where virtualized servers come into and out of existence, and workloads are constantly being moved about and scaled up and down to meet variable demand, calls for new design patterns, processes and even culture. One of the most well known descriptions of these new paradigms is the Twelve Factor App (12factor.net), which describes elements of cloud native applications. Many of these needs are squarely met through the Spring Framework, others require support from other systems. In this session we will examine each of the twelve factors and present how Spring, and platforms such as Cloud Foundry satisfy them, and in some cases we’ll even suggest that responsibility should shift from Spring to platforms. At the conclusion you will understand what is needed for cloud-native applications, why and how to deliver on those requirements.
Devops: Who Does What? - Devops Enterprise Summit 2016cornelia davis
Within the IT organizational structures that have dominated the last several decades roles and responsibilities are fairly standardized. But with the dramatic changes that DevOps practices and supporting toolsets bring, many are left feeling a bit off balance - it’s no longer clear who is responsible for even things as “straight-forward” as development or operations.
In this talk I will take traditional roles that are distributed across fairly standard IT structures and sort them into a new organizational context. What is the role of the Enterprise Architect? Who does capacity planning and how? How can change management step out of the way all while still satisfying the requirements of safe deployments? How do agile teams interface with personnel responsible for maintaining legacy systems? I’ll leave the audience with a blueprint for a new organizational structure.
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.
Cloud Native: Designing Change-tolerant Softwarecornelia davis
Delivered at Interop ITX 2017: http://info.interop.com/itx/2017/scheduler/session/cloud-native-designing-change-tolerant-software
Cloud-native applications are characterized by highly distributed topologies consisting of many relatively small components (yup, usually called microservices). But the thing that sets them apart from the previous generation of apps is that they are expected to function flawlessly even while the environment they are running in is constantly changing, or even failing. All of this requires applying a new set of design patterns and practices and this session will introduce the key ones. The Twelve Factor App (12factor.net) is a high-level articulation of some of these techniques that you may well have heard of, but its descriptions are relatively dense and the industry knowledge has evolved a fair bit since its publication.
Cornelia Davis will go through the best practices for cloud-native applications and clear some of the mystery that shrouds 12-factor today. At the conclusion, attendees will understand what is needed for cloud-native applications, as well as why and how to deliver on those requirements.
Devops @ VMworld 2015 Presentation.
DevOps requires a separation of concerns between the application-focused teams and the platform-focused teams. While Platform and Application Operations have many similarities (monitor, logs, scale, upgrade, etc.) each is done with a different frame of reference. This workshop will provide an in-depth view into how a modern platform like Pivotal Cloud Foundry can eliminate the barriers between Development and Operations.
The workshop will showcase the difference in contexts for the application operations and platform operations teams, including monitoring, log analysis, capacity management, and upgrading. As well as show how separating the concerns of application operators (and application teams) from platform operators can remove the barriers between Dev and Ops. At this session we bring together both Dev and Ops with a combination of presentations and demos highlighting the capabilities of a modern platform. Monitor, log, scale, upgrade, and more, all with an integrated and auditable workflow for developers and operators.

At this joint NYC Cloud Foundry and NY PHP meetup, we'll discuss the shift to Platform-as-a-Service and what it means for PHP development on the cloud.
First, we'll take a look at the "traditional" cloud Infrastructure-as-a-Service (virtual servers and disks) model and describe how Platform-as-a-Service builds upon it to provide the runtimes and data services for hosting PHP applications.
We'll then demonstrate how a PHP developer can use buildpacks and services within a Cloud Foundry PaaS to deploy scalable and resilient apps to his or her cloud of choice.
Along the way we'll compare the variety of buildpacks available to PHP developers, show techniques for binding to services, and highlight best practices for creating born-on-the-cloud apps based on a microservices architecture.
Special thanks to Dan Mikusa for helping with the buildpack comparison.
PHP developers: Please give all three build packs a try. Provide your feedback and submit pull requests on GitHub.

Linux Collaboration Summit Keynote: Transformation: It Takes a Platformcornelia davis
The last decade has seen a revolution in the manner in which digital experiences are brought to consumers. The companies who are not just meeting increased consumer expectations, but are defining them, are operating within very different organizational structures than their predecessors, and are wrapping new processes around them. And they are using a fundamentally different toolset than before. In this talk we will cover a set of processes that serve this new paradigm and we’ll study the patterns that must be present in supporting software development and runtime platforms.

Declarative Infrastructure with Cloud Foundry BOSHcornelia davis
Initially built to deploy and manage the Cloud Foundry “Elastic Runtime”, the platform that allows application developers and operators to easily deploy and manage applications and services through the entire app lifecycle (including production!), Cloud Foundry BOSH is a system that manages any virtual machine clusters of arbitrarily complex, distributed systems. You define your release through packages (what gets installed on the VMs), jobs (what is run on the VMs) and a deployment manifest (declaration of the cluster) and BOSH will first deploy and then continue to maintain your cluster to match that desired state. The result is a self-healing, eventually consistent system that markedly reduces the operational burdens and supports a great number of other Devops functions such as canary, zero-downtime upgrades, autoscaling, built in high availability and more. In this session we’ll show you how to create, deploy and manage a BOSH release, and we’ll watch what BOSH does when bad things happen.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
