Codemotion DevCast: App Modernization in the Cloud
Download as PPTX, PDF1 like58 views
This document discusses app modernization and how moving applications to the cloud on Azure can provide benefits. It outlines the app modernization continuum from refactoring existing applications to rebuilding new serverless applications. Key techniques discussed are containers, microservices, and serverless computing. Containers can help with modernization by allowing existing applications to lift and shift to containers for improved scalability. Microservices and serverless options further improve agility, productivity and operational efficiency. The document emphasizes that Azure supports a hybrid cloud approach and provides services for infrastructure, platforms and serverless applications.

- 5. 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.
- 6. 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
- 7. What are microservices? APP APP APP Monolithic Large, all-inclusive app Microservices Small, independent services A Software Architectural Style Applications are composed of small, independent modules that communicate with each other using well-defined APIs. Not platform specific. Decoupled These service modules are highly decoupled building blocks that are small enough to implement a single functionality but together can form larger systems 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.
- 8. How can containers help your app modernization journey? From traditional systems to a portfolio of modern apps 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 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
