The 12 Factor App methodology provides guidelines for building software-as-a-service applications in the cloud. It advocates for codebases that are tracked in revision control, explicit declaration of dependencies, separation of configuration from code, treating backing services as attached resources, and strict separation between build, release, and run stages. The methodology also includes guidelines for processes, port binding, concurrency, disposability, keeping development and production environments similar, and treating logs as event streams. Following the 12 factors can help applications maximize portability, be more robust and agile, and scale smoothly by avoiding reliance on implicit tools or behaviors.
In this session, we will see how we can monitor our applications & cloud resources performance from dashboards and will setup alerts.

Docker is a system for running applications in isolated containers. It addresses issues with traditional virtual machines by providing lightweight containers that share resources and allow applications to run consistently across different environments. Docker eliminates inconsistencies in development, testing and production environments. It allows applications and their dependencies to be packaged into a standardized unit called a container that can run on any Linux server. This makes applications highly portable and improves efficiency across the entire development lifecycle.
Here are the key steps to create an application from the catalog in the OpenShift web console: 1. Click on "Add to Project" on the top navigation bar and select "Browse Catalog". 2. This will open the catalog page showing available templates. You can search for a template or browse by category. 3. Select the template you want to use, for example Node.js. 4. On the next page you can review the template details and parameters. Fill in any required parameters. 5. Click "Create" to instantiate the template and create the application resources in your current project. 6. OpenShift will then provision the application, including building container images if required.

While this provides an introduction, there is still more to learn about optimizing Docker usage and avoiding common pitfalls.
Red Hat is a leading provider of open source solutions, founded in 1993. It was acquired by IBM in 2019 for $34 billion. Red Hat's flagship products are Red Hat Enterprise Linux and OpenShift, an enterprise Kubernetes platform. OpenShift provides a full platform for developing, hosting, and managing containerized applications, and includes additional services beyond just Kubernetes. It offers advantages for security, automation, and developer experience compared to managing raw Kubernetes. Operators are an innovative approach in OpenShift to package and automate application logic using Kubernetes as the automation engine.
DevOps is a software engineering culture and practice that aims to unify software development (Dev) and software operation (Ops) teams. The main goals of DevOps are to achieve shorter development cycles, increased deployment frequency, and more dependable releases that are closely aligned with business objectives. DevOps advocates for the automation and monitoring of all steps in the software development process, from integration and testing through release, deployment, and infrastructure management.
Prometheus is an open-source monitoring system that collects metrics from instrumented systems and applications and allows for querying and alerting on metrics over time. It is designed to be simple to operate, scalable, and provides a powerful query language and multidimensional data model.

When DevOps talks meet DevOps tactics, companies find that Continuous Integration is the make or break point. And implementing CI is one thing, but sustainable CI takes a little bit more consideration. CI is not all about releases, it is also about knowing more about how your software delivery pipeline works, it's weak points, and how you are doing over time. Join CloudBees and cPrime as we discuss best practices for facilitating DevOps pipelines with Jenkins Workflow and reveal how the workflow engine of Jenkins CI and “Agilecentric” Devops practices together, support complex control structures, shortens the development cycle, stabilizes environments and reduces defects.

This document provides an overview of Red Hat's OpenShift Platform-as-a-Service (PaaS). OpenShift simplifies and automates the development, deployment and scaling of applications. It allows developers to focus on coding instead of managing infrastructure. OpenShift runs applications securely in isolated containers (gears) on top of Red Hat Enterprise Linux. Developers can use integrated tools or a web console to develop, build and deploy applications. OpenShift then automatically scales applications based on demand. The open source OpenShift Origin project allows organizations to run their own private PaaS or contribute to the community.
This document provides an overview of continuous integration (CI), continuous delivery (CD), and continuous deployment. CI involves regularly integrating code changes into a central repository and running automated tests. CD builds on CI by automatically preparing code changes for release to testing environments. Continuous deployment further automates the release of changes to production without human intervention if tests pass. The benefits of CI/CD include higher quality, lower costs, faster delivery, and happier teams. Popular CI tools include Jenkins, Bamboo, CircleCI, and Travis. Key practices involve automating all stages, keeping environments consistent, and making the pipeline fast. Challenges include requiring organizational changes and technical knowledge to automate the full process.
The Twelve-Factor App methodology outlines best practices for building software-as-a-service apps. It recommends (1) storing code in version control, deploying the same code across environments, and avoiding multiple codebases; (2) explicitly declaring and isolating dependencies; and (3) storing configs in environment variables to separate config from code.
