**Course Title:** Cloud Platforms: Foundations and Applications **Section Title:** Cloud Service Models **Topic:** Deploy a virtual machine using IaaS and a simple application using PaaS.(Lab topic) **Introduction** In this lab topic, we will guide you through the process of deploying a virtual machine using Infrastructure as a Service (IaaS) and a simple application using Platform as a Service (PaaS). This hands-on experience will help you understand the concepts of IaaS and PaaS, which were covered in previous topics. **Objective** By the end of this lab, you will be able to: * Deploy a virtual machine using IaaS * Deploy a simple application using PaaS * Understand the difference between IaaS and PaaS **Lab Environment** For this lab, we will be using Amazon Web Services (AWS) as our cloud provider. You will need to create an AWS account if you haven't already. You can sign up for a free tier account using the following link: https://aws.amazon.com/free/ **Deploying a Virtual Machine using IaaS** IaaS provides you with virtualized computing resources, such as virtual machines (VMs). In this section, we will deploy a VM using AWS. **Step 1: Launch an EC2 Instance** * Log in to your AWS management console. * Navigate to the EC2 dashboard. * Click on "Launch Instance" and choose your desired operating system (e.g., Ubuntu). * Choose the instance type (e.g., t2.micro) and click "Next: Configure Instance Details". * Configure your instance details (e.g., number of instances, instance type, tenancy) and click "Next: Add Storage". * Configure your storage (e.g., add a new volume) and click "Next: Add Tags". * Add tags to your instance (e.g., name, environment) and click "Next: Configure Security Group". * Configure your security group (e.g., add a new rule for SSH) and click "Review and Launch". * Review your instance details and click "Launch". **Step 2: Connect to Your EC2 Instance** * Go to the EC2 dashboard and select your instance. * Click on "Actions" and select "Connect to instance". * Choose the connection method (e.g., SSH) and click "Connect". * You will see a connection dialog with instructions on how to connect to your instance. **Deploying a Simple Application using PaaS** PaaS provides you with a platform for developing, running, and managing applications without worrying about the underlying infrastructure. In this section, we will deploy a simple Node.js application using AWS Elastic Beanstalk. **Step 1: Create an Elastic Beanstalk Environment** * Log in to your AWS management console. * Navigate to the Elastic Beanstalk dashboard. * Click on "Create environment" and choose "Web server environment". * Choose your platform (e.g., Node.js) and configure your environment details. * Click "Create environment" to create your environment. **Step 2: Deploy Your Application** * Clone or create a new Node.js project (e.g., a simple "Hello World" application). * Initialize a new Git repository and commit your code. * Go back to the Elastic Beanstalk dashboard and select your environment. * Click on "Upload and deploy" and upload your code. * Click "Deploy" to deploy your application. **Conclusion** In this lab, you deployed a virtual machine using IaaS and a simple application using PaaS. You have seen firsthand the difference between IaaS and PaaS, and how each service model can be used to deploy different types of applications. **Practical Takeaways** * IaaS provides you with virtualized computing resources, such as virtual machines. * PaaS provides you with a platform for developing, running, and managing applications without worrying about the underlying infrastructure. * Each service model has its own strengths and weaknesses, and choosing the right model depends on your application's needs. **Lab Exercises** * Deploy a virtual machine using IaaS and experiment with different instance types and security groups. * Deploy a simple application using PaaS and experiment with different platforms and configuration options. **Resources** * AWS Documentation: https://aws.amazon.com/documentation/ * Elastic Beanstalk Documentation: https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/Welcome.html **Leave a comment or ask for help** If you have any questions or need help with this lab, please leave a comment below.
