This document discusses app modernization and moving applications to the cloud. It notes that most IT budgets are spent on maintaining existing systems rather than new initiatives. App modernization can help by moving applications to containers, microservices, and serverless architectures. This allows lifting applications to the cloud which provides auto-scaling, redundancy, and frees up resources for innovation. The document outlines strategies like rehosting, refactoring, and rewriting applications using containers, Kubernetes, and serverless functions on Azure. This modernization journey provides agility, time to market, cost savings, and simplifies IT operations.

- 11. The journey to the (hybrid) cloud DevOps Deliver faster and more reliably On-Premises Application Infrastructure Data + Intelligence
- 12. (Hybrid) Cloud app continuum Agility – Time to Market – Total Cost of Ownership – IT Simplification EngineeringComplexityandCost Existing on- premises applications VMs Rehost Containers & App Services Refactor Microservices Rearchitect Serverless Rebuild New SaaS apps Replace App Modernization Lift & Shift
- 13. Modernizing web apps with Azure No consistent service level/uptime. No scaling if unexpected traffic. Reduced agility/lack of flexibility. Monolithic applications, legacy code. Lack of resources for new initiatives. Limited technical support. Challenges App Service benefits Built-in no-configuration auto- scaling, load balancing and failover. CI/CD/DevOps out of the box. Serverless options for all app scenarios. Frees IT to focus on innovation. Use existing skills, tools & frameworks.
- 14. What is a container? Virtualize the hardware VMs as units of scaling Virtual machines App Containers Virtualize the operating system Applications as units of scaling Container App
- 15. What are microservices? Monolithic APP APP APP Microservices Large, all-inclusive app Small, independent services Decoupled These service modules are highly decoupled building blocks that are small enough to implement a single functionality but together can form larger systems A Software Architectural Style Applications are composed of small, independent modules that communicate with each other using well-defined APIs. Not platform specific. Independently versioned, deployed & scaled With a microservices architecture, developers can create, manage and improve application services independently, even using different languages Containers provide the consistent format and isolation desired by microservices.
- 16. How can containers help your app modernization journey? From traditional systems to a portfolio of modern apps Continuous innovation with DevOps 46x more frequent for code delivery2 1: Datadog Report: 8 Surprising Facts About Real Docker Adoption; 2: 2017 state of DevOps Report App Container App Existing/New Applications Lift and shift to containers Each host often runs 8 containers at a time1 Microservices Seconds to deploy, churns 12x faster1
- 17. Containers in Azure Choice of developer tools and clients Azure Container Registry Docker Hub App Service Deploy web apps or APIs using containers in a PaaS environment Service Fabric Modernize .NET applications to microservices using Windows Server containers Kubernetes Service Container Instance Scale and orchestrate Linux containers using Kubernetes Ecosystem Bring your Partner solutions that run great on Azure Elastically burst from your Azure Kubernetes Service (AKS) cluster
