<> @zupinnovation zup.com.br NIST National Institute of Standards and Technology "Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction."

<> @zupinnovation zup.com.br Cloud Native Applications

<> @zupinnovation zup.com.br Cloud Native “Cloud-native is an approach to building and running applications that exploits the advantages of the cloud computing model.”

<> @zupinnovation zup.com.br Cloud Native “Cloud-native is a different way of thinking and reasoning about software systems. It embodies the following concepts: powered by disposable infrastructure, composed of bounded, scales globally, embraces disposable architecture.”

<> @zupinnovation zup.com.br Cloud Native “Independent DURS ultimately comes up in every discussion on cloud-native concepts; to independently Deploy, Update, Replace and Scale.”

<> @zupinnovation zup.com.br Cloud Native “Cloud-native is more than a tool set. It is a complete architecture, a philosophical approach for building applications that take full advantage of cloud computing.”

<> @zupinnovation zup.com.br Cloud Native “Cloud-native technologies empower organizations to build and run scalable applications in modern, dynamic environments such as public, private, and hybrid clouds. Containers, service meshes, microservices, immutable infrastructure, and declarative APIs exemplify this approach.”

<> @zupinnovation zup.com.br Cloud Native Cloud-native is a term used to describe container-based environments.

<> @zupinnovation zup.com.br Cloud Native A set of good practices to optimize an application in the cloud through: Containerization Orchestration Automation

<> @zupinnovation zup.com.br Challenges

<> @zupinnovation zup.com.br Challenges ● Rotes ● Security ● Upgrade database and language ● Backups ● CI/CD

<> @zupinnovation zup.com.br Trade-off ● Complexity ● Risk ● Cost ● Knowledge management

<> @zupinnovation zup.com.br Survival Guide

<> @zupinnovation zup.com.br Tips Use Managed Services, Please (Dan Moore) It's Ok if you're not running Kubernetes (Mattias Geniar) Why every Engineer Should Be a cloud Engineer (Michelle Brenner) Source Code Management for Software Delivery (Tiffany Jachja) Containers aren't Magic (Katie McLaughlin) KISS It (Chris Proto)

<> @zupinnovation zup.com.br Infrastructure as Code ● Alignment with DevOps ● Speed and efficiency ● Consistency

<> @zupinnovation zup.com.br GitOps ● Git as the single source of truth ● Git is the single place we operate ● All changes are observable/verifiable ● CI/CD

<> @zupinnovation zup.com.br The 12 Factors App 1. Codebase 2. Dependencies 3. Config 4. Backing services 5. Build, release, run 6. Process 7. Port binding 8. Concurrency 9. Disposability 10. Dev/prod parity 11. Logs 12. Admin processes

<> @zupinnovation zup.com.br Old, but gold

<> @zupinnovation zup.com.br Microservices “Certainly, we always read great things about the microservices architectures implemented by companies like Netflix or Amazon. So let me ask a question: how many companies in the world can be Netflix and Amazon?” Conway's law

<> @zupinnovation zup.com.br Circle Deploy: The evolution of deployment ● Intelligent and simple segmentation ● Multiple parallel releases of the same application ● Improvements: ○ Best test hypothesis ○ Solve bug faster ○ Easier development process ○ More reliable releases

<> @zupinnovation zup.com.br Circle Deploy: The evolution of deployment This kind of deployment makes it possible to create a segment with your clients' specific characteristics At the same time, submit several versions of the same application to test this circle of users.

<> @zupinnovation zup.com.br CharlesCD: the deployment in circles on Kubernetes clusters “The concept behind the tool goes back to the theory proposed by the biologist Charles Darwin (1809-1882), in which evolution goes by the adaptation to a new environment. In the development scenario, this evolution goes by constant improvements on the applications to build and test hypothesis in order to implement more reliable releases.”
