  12. The value of PaaS 12 | Mix & match components to build a scalable solution | Auto-scale possible | Embedded security | Open for full customization & integration | Hybrid is crucial | Build on an evolving platform | Features get added | Monitoring by design | Deployment automated | Easy to add new features (example: data analytics) | Focus on creating value, less on building infrastructure
  13. 13 5 Patterns for app modernization
  14. Move to the cloud 14 “What your application works with” Data “What your application does” Code “What your application runs on” Infrastructure Unified Management • Security • Governance • Tools • DevOps Containers • Microservices • Data lake • Serverless
  15. Modernizing with container technology 15 | Build once, run everywhere | Cross platform: on the edge, in the cloud, in the data center | Small effort, biggest gains in deployment DeploymentModernizationExisting application VM Container Azure Container Registry Convert Publish Azure Kubernetes Registry
  16. Carve out with micro services 16 | A journey from monolith to micro services | Carve out functionality | Phased out approach to reduce complexity & risk | Ship services as independent containers | Services are owned and adapted by teams | PaaS, unless… | API management as routing facade to hide migration & implementation logic Monolith App Large, all-inclusive app Micro services App App Small, independent services Session by Tom Kerkhove at Ignite:
  17. New applications Scenario specific services Data strategy 17 | Get data from silos | Analytics & insights can result in new applications or features Existing applications Functionality & Interaction Data integration & pipelines Scheduling & pipelines Publish Raw Data Curated Data Data Stream Async Batch Analytics Predictions

  1. Intro Why modernization Strategies for modernization 5 Services & patterns to help customers in modernizing
  2. Companies are suddenly selling & shipping software, with their products Examples Buhler with chocolate machines Energy companies delivering subscriptions Transport & logistics with new business models
  3. Data is often locked up in silo’s and integration can help Mix & match data Open up for data consumption & platforms Extend & automate Codit has been doing this for years and can build the basis for any modern application *
  4. When transforming the business, it’s all about data Insights and retrospective information Enriching data with new unstructured data Also predict and prevent
  5. Two motivations to modernize: Breathe new life in existing applications Extend legacy applications with new functionality (per every animated step): Cycles of maintenance happen in the traditional datacenter and make customer rethink Adding features and functionality Business success requires more scale Compliance & security There are two approaches: Migration: focusing on rehosting on different infrastructure Modernization: leverage more cloud native functionality
  6. Some apps might be outdated and cannot follow the business needs. Customers want to use IT budgets for business benefits, and not just for maintenance
  7. Applications are changing Multiple front ends: bots, apps, API’s and web Multiple views & different roles Data & A.I. Deliver and ship more frequently Scale and tune for what is needed
  8. Existing: customers don’t want to move the entire portfolio at once Lift & shift: focus on infrastructure, less cloud native benefits Optimize: better scale, enhance parts of the application Modernize: strategic move, refactor code & redesign architecture
  9. Lift & shift : delay often means cancellation Optimize: more security, unlock data, leverage containers Modernize:refactor & add new functionality
  10. Customers want to focus on Applications & Data – and consider the underlying parts as commodity The choice between PaaS & SaaS, is pretty much a build vs buy It takes time to get to PaaS, focus on the strategic apps first
  11. Customers own and evolve the solution : Systems become products Scale & security CI / CD Infrastructure becomes part of the deployment
  12. You can move parts separately (hybrid) Containers, micro services, data lake & serverless should ben mentioned
  13. A popular choice for quick, no-code application modernization is container technology. Apps are abstracted from the environment in which they run. Deploy easily and consistently, where you want: private data center, the public cloud, or even a developer’s personal laptop. Iterate & version control
  14. Microservices architecture means breaking large software projects into smaller, independent, and loosely coupled modules. When using microservices, each service is independent, and each service is a new project that can be developed on its own schedule, using any language or stack that best fits current requirements. Scaling up is easier than with traditional VMs or even Containers – it just requires deploying additional services as needed. Microservices make application maintenance easier - developers work on individual services, so the code base a developer needs to handle is smaller, easier to manage and easier to understand. Microservices-based applications are also more resilient and stable - if one or more services should fail, the application will continue to work. Individual service instances can easily be upgraded, changed or taken down without impacting the entire application negatively.
  15. Data integration & unlocking data – streaming or ETL’ing into a data lake Perform analytics or Machine Learning Expose data & functionality through API management Build new scenarios or add new features, leveraging these new insights
  16. With Azure, you can build applications without provisioning and managing infrastructure using a fully managed platform where scaling, availability, and performance are handled for you. The keyword here is serverless, a cloud-computing execution model in which the cloud provider dynamically manages the allocation of machine resources. This approach allows developers to focus on code without distractions – if they do not have to think about infrastructure, they will be more productive. Serverless functions are optimized for any scenario where logic needs to be run in response to an event – and this definition encompasses a lot of application scenarios. For legacy applications, serverless also offers an attractive way to extend the functionality of an existing application without touching the actual source code which might be undocumented or outdated. Instead of implementing new functionality in the main application, it’s much easier and faster to surround it with pockets of new functionality using technologies like serverless functions that can be triggered via APIs and events. This also enables you to use advanced cloud-only capabilities like machine learning or AI with existing legacy applications that were built before such technologies were widely available.
  17. DevOps is the union of people, process, and tools to enable continuous delivery of value to end users. The contraction of Dev and Ops refers to replacing silo’ed Development and Operations disciplines with multidisciplinary teams that work together with shared and efficient practices and tools. A converged DevOps cycle provides the ability to execute on ideas quickly and iterate on feedback rapidly while at the same time maintaining highest levels of quality. For Microsoft, DevOps encompasses the whole application lifecycle, from idea to application running in production. DevOps is built into the foundation of Azure, not bolted-on like with other cloud vendors. Azure DevOps lets you plan smarter, collaborate better, and ship faster with a set of modern developer services. You can use all the Azure DevOps services or choose just what you need to complement your existing workflows and toolchains.
  18. Green field solutions start with a blanc sheet There are reference architectures & best practices we can help with Pick the right components and leverage cloud native benefits
  19. Having built thousands of integration processes, since 2000, Codit has built a big experience in integration and system connectivity.  Because of our dedicated focus, we can say that we have built an extensive set of best practices and tooling around Azure Solutions and integration (AIS, APIManagement) in general. Therefore, we often provide quality assurance or review on projects of customers; worldwide.  The quality review contains 3 different parts:   System review.  This part focused on the actual system setup and configuration.  Here we are focusing on the aspects around the setup of the Azure subscriptions and organization of Azure artifacts, including performance, security and cost management. Application review.  In this part of the review, we do a review of the actual development artifacts and the different application settings.  We look to see if everything is ready for change and flexible enough for your organization. Project & Methodology review.  We review methodology and procedures used for Azure projects. Source control, testing strategy, build and deployment procedures will be evaluated. Operations review. We review processes and approach used for Monitoring and Operating the Azure environment and implementations deployed on the Azure portal.
