Getting Started with Cloud Foundry on Bluemix
- 1. IBM Bluemix Getting Started with Cloud Foundry
- 2. ▪ Introduction to PaaS (5 min) ▪ Cloud Foundry overview (5 min) ▪ Bluemix console exploration (5 min) ▪ Creating and updating an app (5 min) Agenda
- 3. Section 1 PaaS and IaaS: Where are we and how did we get here?
- 4. Where do websites live? We all know what a website is. Most people are unaware of what makes them tick.
- 5. This is the standard architecture for your typical web application. As the web and underlying applications have evolved, so has this architecture. Client-Server Architecture
- 6. Moore’s Law “The number of transistors incorporated in a chip will approximately double every 24 months.” -Gordon Moore, 1975 Credit: Intel
- 7. The first path to the cloud Infrastructure as a Service (IaaS)
- 8. Customer Managed Service Provider Managed Infrastructure as a Service Code Data Runtime Middleware OS Virtualization Servers Storage Networking Code Data Runtime Middleware OS Virtualization Servers Storage Networking Platform as a Service Built on technologies: The key to rapid application development is optimal abstraction. The PaaS and IaaS models help deliver the right level for developers. The stack is not your friend
- 9. Section 2 Cloud Foundry: What is the platform, anyways?
- 10. The industry-leading open PaaS Cloud Foundry • Clouds - Public, Private, Local Choice • Runtimes - node.js, spring, ruby on rails, byob… • Services - MongoDB, MySQL, Redis, Twilio… • Decreased time to deployment aka faster G2M Benefits • Increased environment parity • Services can be self-assembled to create integrated apps • Elastically scale applications • Removes worries of OS and middleware patches • Development methodologies must adapt to tech Drawbacks • Requires dev awareness of platform limitations and best practices • Control over underlying middleware and infrastructure is limited
- 11. •Platform is abstracted as a set of large-scale distributed services •Components are dynamically discoverable and loosely coupled •Uses Cloud Foundry Bosh to operate the underlying infrastructure from the IaaS provider •Uses a dynamic router to shape and route all traffic and orchestrate load balancing •Droplet Execution Agents (DEAs) are responsible for the app lifecycle •Health Manager monitors and maintains application uptime •Buildpacks detect app runtime and compile source code into executable binaries Cloud Foundry Architecture
- 12. Flexible Compute Options to Run Apps / Services Instant Runtimes Containers Virtual Machines Platform Deployment Options that Meet Your Workload Requirements Bluemix Public Bluemix Dedicated Bluemix Local* DevOps Tooling Your Own Hosted Apps / Services Integration and API Mgmt Powered by IBM SoftLayer In Your Data Center + + + + + Catalog of Services that Extend Apps’ Functionality Web Data Mobile AnalyticsCognitive IoT Security Yours + Cloud Foundry is the underlying PaaS behind Bluemix. It enables teams to practice continuous delivery by making it easier to deploy, run, and manage apps. Where does Cloud Foundry fit in?
- 13. Types of services •Accounts for a SaaS application •Managed database on a multi-tenant server •Plans for messaging providers How it works •When a user adds a service, an instance of that particular service is provisioned •A service broker handles communication between CF and the service itself •Service processes run on service nodes or with external as-a-service providers Services allow users to provision resources on demand Cloud Foundry Services
- 14. Section 3 & 4 The console: How do I use this thing?
- 15. 1. Find your desired runtime in the catalog 2. Select the runtime, make sure you are in your desired org and space, then fill in the Name and Host fields in the configuration box 3. Click ‘Create’ Your app will now stage and deploy. Once it is finished, hit ‘View App’ link to access your running app! Creating an app The simplest way to get a functioning app up on Bluemix is to create an app from one of the supported runtimes in the catalog. 1 2
- 16. 1. Download the starter code 2. Open up the public/index.html file using your favorite text editor 3. Change the value inside the h1 element on line 18 to read “Hello World!” and save 4. Push the app back to Bluemix using the cf login and the cf push commands Editing your code Download your code to edit it locally and push the updated version back to Bluemix using the CF CLI 1 2 3
