Using Azure DevOps to continuously build, test, and deploy containerized applications with ease
- 1. Using Azure DevOpsto continuously build, test, and deploy containerized applications with ease Adrian Todorov, Cloud Solutions Architect @todorov_adrian | linkedin.com/in/adriantodorov
- 2. Hello! I am AdrianTodorov love heavily
- 5. developers I need tocreate applications at a competitive rate without worrying about IT New applications run smoothly on my machine but malfunction on traditional IT servers My productivity and application innovation become suspended when I have to wait on IT
- 6. IT I need tomanage servers and maintain compliance with little disruption I’m unsure of how to integrate unfamiliar applications, and I require help from developers I’m unable to focus on both server protection and application compliance

- 12. Key DevOps Practices Infrastructureas Code Continuous Integration Continuous Deployment Automated Testing Release Management Performance Monitoring Availability Monitoring Load Testing & Auto Scale Automated Recovery (Rollback & Roll Forward)
- 13. Why Containers? Developers Enable ‘write-once,run-anywhere’ apps Enables microservice architectures Great for dev/test of apps and services Production realism Growing Developer Community Operations Portability, Portability, Portability Standardized development, QA, and prod environments Abstract differences in OS distributions and underlying infrastructure Higher compute density Easily scale-up and scale-down in response to changing business needs DevOps

- 15. container Not a realthing. An application delivery mechanism with process isolation based on several Linux kernel features. (what a process can see) (what a process can use)
- 16. What is ? An open source container runtime Mac, Windows & Linux support Command line tool “Dockerfile” file format for building container images The Docker image format with layered filesystem

- 42. Maersk uses AKSfor a customer service process to elevate NSAT, an industry-wide challenge Needs: Get near-real-time data to provide better customer service Collect data for future Machine Learning driven features Challenges: Compute & memory intensive features Data integration difficulties Limited organisational experience in Cloud & Kubernetes Requirements: Spend less time on container software management Automation and continuous delivery Full visibility to application, container and infrastructure Fine grained security and access control Click icon to learn more
- 43. Architectural approach 1. AzurePipelines for automation and CI/CD pipelines; adding Terraform for further automation 2. Key Vault to secure secrets and for persistent configuration store 3. Azure Monitor for containers provides better logging, troubleshooting, with no direct container access 4. RBAC control for fine grained Kubernetes resources access control Firewall App Gateway AKS w/ RBAC Azure Monitor Azure Pipeline SQL Database Cosmos DB Performance Document DB Key Vault Event Hub Batch processing Event Simulation Data Factory Data Management Gateway On-premises database Express Route Service Bus Internal Queuing SQL Database
- 44. Results Reduced environment provisioning timefrom 1+ weeks to 2.5 hours Deploy times reduced to minutes with the introduction of Terraform Increased developer autonomy with ARM Templates and Terraform <> Less time spend on managing secrets with AKS and Key Vault AKS and CaaS can potentially save 33% on run cost 100% automated production deployments

- #11 Developers are going to come out with the idea, they are going to implement the idea, they are going to take the code that they write and then build it, test it, put it through the release process until it finally gets out into production where your customers can use it Every new feature that you build into your application is going to go through that lifecycle After your customers can get their hands on it, you can start to learn from it Development team can look at the customer usage data from the application, they can get feedback from the customer and they can start to plan and take educated decisions on what they want to do next 2 Important things to note about this development lifecycle First: The speed of the completing that loop (to build a new feature and to get it into the hands of your customers and have your customers start using it and learning from their usage) – the speed of completing that loop determines your business agility The faster we’re able to iterate through the loop, the more responsive you will be to customers and the quicker you will be able to innovate We need to focus on improving that loop as quickly as we can Second thing to note: Developers are adding value to the customer when they are working on the left side, writing new code and building new features Any time the developers spend in the middle of this diagram, all of this time will be lost in the eyes of the customer. Either building the delivery pipeline or handholding changes through that pipeline, all of that time will be lost in the eyes of your customers So what you want to do is maximize your time your developers are writing new features and minimize the time developers are spending in the middle
- #12 And it’s really those 2 things that make the heart of the DevOps, the heart of DevOps is any efficiencies you might make, that can you drive, that helps you loop through this faster. And this is why it’s so confusing to implement DevOps. There are many things you can do here. You can make organizational changes, cultural changes, process changes, tool changes and I think that’s okay, anything that you can use to make improvements to this delivery pipeline and feedback loop count as DevOps
- #13 You might also hear Pipeline as Code. Another newer term is GitOps. All of these practices help you
