The AWS users that will run the template, will have to provide values to those parameters, after they upload the .template file. A tutorial for developers that want to learn about how to build modern applications on top of AWS. Follow. Out of the box, customers have immediate access to a large and growing repository of dozens of multi-service architecture patterns, spanning the most commonly used  combinations on the AWS Platform. AWS Cloudformation. Infrastructure as code is a technique whereby we create machine-readable files that describe our infrastructure. Apart from the required Resources section, we will have a look at some of the optional ones, such as Parameters, Conditions, Mappings and Metadata. After the completion of our stack, we can navigate to different screens and check the resources created (EC2, VPC, Security Groups, Route Tables, etc). At this point, we have a complete script that we could run and allow us to SSH into our servers, and check that everything have been set up they way they should. Configuration management tools like Chef, Puppet, and the oth… You need to remember the folder that this key pair file was saved locally, and change the permissions of the file depending on whether you are using Linux, Mac OS or Windows. All rights reserved. © 2020, Amazon Web Services, Inc. or its affiliates. Please note here that enabling the creation of private resources, will incur a very small cost, as AWS charges $0.045/hour as the Price per NAT gateway. Terraform is a vendor agnostic tool and can manage infrastructure for multiple resource providers (for example AWS, Google Cloud, Azure, Aviatrix, Heroku, Oracle, etc.). Example of how to use AWS CodePipeline and AWS CloudFormation together for IaC. In this part we’ll just group the Parameters we’ve defined in the beggining of our script, so that they are displayed in a specific way on the user interface. This is in the form of a small Python library, which codifies common patterns in our infrastructure. This will be the biggest section of our template file (at least in the specific example), as we are going to define each resource needed for our infrastructure, as well as the associations between some of those. As emphasised in a recent article (in French) on this blog, Infrastructure as Code is a crucial matter to agile software development in the cloud. Our goal is to be able to host a highly available website, which will be served from EC2 instances located in private subnets (for better security). Infrastructure as Code (IaC) is gaining popularity as a strategy for improving the consistency, resilience and reusability of IT services. This needs to be done before we start running the file, as its value should be passed in the Parameters section. Finally, we review all information regarding the stack, and click Create Stack. We then create 2 private route tables, as we have 2 NAT Gateways and we cannot have a single route (in our case to 0.0.0.0/0) in a route table pointing to more than one NAT Gateways. What follows is the Mappings section, at which we have all AMI ids for the Amazon Linux 2 image, and based on the region that the stack will be created at, the script will choose the appropriate AMI for the EC2 instances creation. These patterns can then easily be assembled declaritively into production-ready architecture. By using AWS Solutions Constructs, you reduce the time and effort required to deliver a production-grade application. For AWS cloud development the built-in choice for infrastructure as code is AWS CloudFormation . We've released a full course on the freeCodeCamp.org YouTube channel to help you learn how to use Terraform. The use of AWS Solutions Constructs makes it easier for customers to consistently and repeatedly create their own well-architected applications. Finally, we associate our 2 public subnets to our public route table (so that all of their resources access the internet though the IGW) and each of our 2 private subnets to a private route table (so that their resources access the internet though the NAT GW). In the future we plan to add support for Terraform as well. Modern Infrastructure as Code (TypeScript) Module 01 1.1 Creating a New Project 1.2 Configuring AWS 1.3 Provisioning Infrastructure 1.4 Updating Infrastructure 1.5 Making Your Stack Configurable 1.6 Creating a Second Stack Phase 4 of #CloudResumeChallenge where I try to deploy to AWS using infra-as-code. In this blog article I compare various ways and tools to create infrastructure as code for AWS and Azure. Sample Template. But, we couldn’t access the content of those websites publicly from a browser. This way we avoid getting charged for resources that we’ll no longer be using. Our next step is to create 2 NACLs for our infrastructure. Requirements. In this post, we are going to see step-by-step, how we can model and provision an environment in AWS, by defining all the needed infrastructure components using Cloudformation. We will be redirected to the Stacks page, from which we can monitor the resources being created, the events that trigger their creation, etc. To do that, we first need to create a definition for the LaunchConfiguration that the ASG will be using to create the instances. AWS Cloudformation, provides a common language for you to describe and provision all your AWS infrastructure resources. If you don’t, by the time that the template finishes running, you will see both them plus the 2 new instances that the ASG will create (it does not count already created instances when checking the DesiredSize attribute). By giving the option to the user to decide on the VPC CIDR block range, and by using the Fn:Cidr function, we can dynamically produce the appropriate CIDR ranges for our subnets, based on the mask size provided by the user during passing the Parameters values, and also taking into consideration the CreatePrivateResources flag. In the specific example, we’ll be using a TargetTrackingScaling policy, checking the number of requests our ALB will be receiving (per target), and scale our target group based on that metric. To create a change set for a stack, submit the changes to the template or parameters to AWS CloudFormation. Please note here, that our NAT Gateways will have to reside on our public subnets. It is used for building, changing, and versioning infrastructure safely and efficiently. We will define one security group for the EC2 instances that will deployed in our public subnets, and another one for the ones deployed at the private ones. A last small piece that we will add to our template file, is the Metadata section. a value of “8” creates a. For example, when I run the template, I’m passing my own IP address (172.58.43.122/32). Terraform is an open-source infrastructure as code software tool. Some example infrastructure as code tools that can be used to provision environments are, Terraform, a cloud agnostic provisioning language. The first thing you need to do is add your Git account in Microtica. So, let’s assume that we have a VPC with a CIDR block value of 10.10.0.0/20, therefore a range of IPs from 10.10.0.0 → 10.10.15.255. will automatically create for us the next 2 subnets: will automatically create for us the next 4 subnets: We could make things even more dynamic, by giving to the user the option to set the number of subnets they want to create (let’s say a Parameter attribute named NumberOfSubnets) and have the CidrBlock key looking like this: In order for the EC2 instances in our private subnets to have access to the internet, we have to create 2 NAT Gateways (1 in each AZ) and the Elastic IPs that will be allocated to them. The user using template should have required permissions to provision infrastructure. But knowing how to define them in a configuration file and use one or two commands to deploy all of … Infrastructure as Code Benefits : What is Infrastructure as Code Tutorial? Okay for example, if you have ten identical web servers … behind a load balancer … and lets say a change has been made … manually to a single server, ... Modern companies need developers who can accomplish business objectives with Amazon Web Services (AWS) ... Infrastructure as code with AWS. Let’s see how we will configure our public security group. Infrastructure as Code is improving DevOps. Infrastructure as Code AWS strategies are powered by the CloudFormation service, which lets you define simple text-based templates, and use them to spin up surprisingly complex cloud architectures. Amazon was the first cloud vendor to offer IAC through CloudFormation, which it launched in 2011. Additionally, customers can leverage features built into the CDK combined with AWS Solutions Constructs to accelerate their development process by using its pre-built patterns to quickly assemble an entire application, using familiar programming languages. The Wonderful World of ASCII Art — Ruby CLI, the Availability Zone that the subnet will reside is determined, an initial CIDR block (in our case that of the VPC), the number CIDRs to generate (we’ll calculate one for every subnet), the number of subnet bits for the CIDR (e.g. Finally, its type will be selected as a value to the InstanceType Parameters attribute. AWS Solutions Constructs are built and maintained by AWS, using best practices established by the AWS Well-Architected Framework. One thing we want to do, is to go to the Load Balancers section (of the EC2 page), and copy the DNS name of the created LB. You can use AWS Solutions Constructs to create a simple static website, using Amazon S3, CloudFront, and AWS Lambda. This allows us to pass the configuration file to AWS and the infrastructure itself will be instantiated (created). By starting with Constructs, it’s easier for customers to ensure that their workload as a whole is well-architected. Finally, we have to associate those two, by adding a listener to the Load Balancer, forwarding all requests to the created Target Group. In this example we’ll use N. Virginia (us-east-1). Ask Not What You Can Do For Your Container Build…, Exploring Kotlin Coroutines and Lifecycle Architectural Components integration on Android, Docker Containers: an absolute prevail over Virtual Machines. In our example, we’ll just define a condition, that will take into consideration the value that the user will pass to the PrivateResourcesCreation parameter declared above. I made an attempt to create a simple and easy to follow tutorial about Infrastructure as Code . You can use the AWS CloudFormation console, AWS CLI, or AWS The AMI that will be used for those instances to be created, will be retrieved from the predefined AWSRegionLinux2AMI list in the Mappings section. » Infrastructure as Code. Hope the above example is helpful, thank you reading! At the end of the Parameters section, we’ll give the option to the user to decide whether they want to create the private resources (EC2 instances, NAT Gateways, Elastic IPs, etc), in case someone wants to remain on the free-tier. There are several ‘infrastructure as code’ frameworks available today, to help customers define their infrastructure, such as the AWS CDK or Terraform by HashiCorp. With the addition of the ALB, we can access the content of our application by hitting the DNS name assigned to the ALB, and the load would be balanced between the 2 servers in a round robin mode (we’ll see how we can do this later on). We want to take things a bit further though, and create an AutoScalingGroup that will be responsible for scaling out/in our application horizontally, based on the criteria that we’ll define. In simple terms, if you want to provision a Virtual Private Cloud or an EC2 instance in AWS, you can write a terraform configuration to automate this process rather than doing it manually from AWS console. Once again, we’ll create one instance in every AZ. In this blog, we will walk you through a use case of logging customer behavior data on web-application and will use Terraform to model the AWS infrastructure. As a next step, we define a Scaling Policy for our ASG, which will describe the criteria based on which we want our EC2 instances to scale in or out. Page 7 . In the current version of Microtica, we support AWS CloudFormation as a way to write cloud infrastructure setup in declarative way (infrastructure-as-a-code). The setup for the private security group will be quite similar, with the only deifference being that CIDR IP range that will accept traffic from, will be the CIDR of the VPC. Initially, we create a public route table and we add a route to the Internet Gateway in case a resource wants to access the internet (0.0.0.0/0). We’ll try to write the code based on the order that we want our resources to be created, but that doesn’t play any role in the actual event execution sequence. At the end of the section, we define a list of EC2 instance types that can be used when creating both the bastion hosts as well as the website instances. For that reason, and also because we want to expose a single endpoint to our end users to access our website servers (and of course balance the load between the instances), we are going to create an Application Load Balancer. AWS CloudFormation, you can maintain your infrastructure just like application source code. Let’s start by defining the AWSTemplateFormatVersion and a short Description: Next, we are going to define a few Parameters, in order to make our script more generic. We then associate our public subnets to our public NACL and the private subnets to the private one. I’m on the record as preferring declarative infrastructure as code (IaC) to imperative versions, such as the AWS CDK. Next, we define the Internet Gateway and attach it to the VPC. AWS Solutions Constructs reduces friction for developers by leveraging all of the benefits of the AWS CDK. If you are new to infrastructure as code as a concept, it is the process of managing infrastructure in a file or files rather than manually configuring resources in a user interface. In this course, I will explain the components of this service and how they operate together to provide you with this feature of provisioning your infrastructure as code. We have chosen t2.micro as the default value, as we don’t want to get charged for EC2 resource usage. As a helper tool, we can use the DependsOn attribute, in order to ensure that the creation of a specific resource follows another. In … AWS Cloudformation is one of the most common examples of how to implement a “stack” or a set of resources that are defined in a configuration file. Since we’re building a high availability infrastructure, we’ll create one EC2 instance that will act as a bastion host, in each AZ. In the described example, in order to write our .template file, we will be using the YAML format . We’ll therefore create subnets in both AZs. Cloudbank contains a representation of our infrastructure as code. Consistently deliver Well-Architected apps, Click here to return to Amazon Web Services homepage, Start Building with AWS Solutions Constructs, See deployment steps and source code in the Developer Guide, Get started with AWS Solutions Constructs. In the described example, in order to write our .template file, we will be using the YAML format . You will build a sample website that leverages infrastructure as code, containers, serverless code functions, CI/CD, and more. Amazon Web Services – Infrastructure as Code. Infrastructure as code is the process of provisioning and managing your cloud resources by writing a template file that is both human readable, and machine consumable. This means that the default settings for the services used in any given Construct are configured with the Well-Architected Framework in mind, reducing the effort required to ensure best practices for the AWS Cloud are being followed. I believe that declarative IaC has a lower total cost of ownership (TCO). During the initial work to develop the resume website, I used the console to set things up. We then try to make the creation of the VPC and Subnets a bit more dynamic, by allowing the user to define the VCP CIDR block they want, as well as the number of subnet bits for every created subnet’s CIDR. Setting up an Amazon VPC, however, can be a complicated task that slows down an IT operations team.. HashiCorp's Terraform is an open source infrastructure-as-code tool that provides an abstraction layer on top of cloud services, such as Amazon VPCs. 2. We start by the VPC, referencing the VpcCidrBlock defined in the Parameters section. AWS Solutions Constructs are vetted architecture patterns, available as an open-source extension of the AWS Cloud Development Kit, that can be easily assembled to create a production-ready workload. At this point, let’s have a closer look on how: For the first one, things are pretty simple, as we use Cloudformaation’s Fn::GetAZs which returns an array with all the AZs for the specific region that we are running the template. Julio starts his talk with examples of some of the most complex clusters of microservices - such as AWS and Netflix. The last thing we need to define before we move on with the creation of our EC2 instances, is the security groups that those instances will be using. But while I prefer declarative to imperative, imperative IaC enables something I consider much worse: infrastructure as imperative programs that generate declarative IaC documents. In order to set everything up along with the creation of our EC2 instances, we’ll provide all the necessary information in the UserData section of our definition. If we take a look at the sample app that cdk created we should see a file at lib/cdk-post-stack.ts.When we open that file we should see that there is some code in it that provisions an SQS queue and an SNS topic. More importantly though, in case we needed to run the same script again (let’s say in order to create the same stack, but for a testing environment) and we wanted a different mask value for our subnets, we would have to find all subnets declarations, re-calculate the IP ranges and manually make all changes to the script. If we keep refreshing the page, we’re able to see that each time we are getting a response from a different web server that is located behind our load balancer. AWS CloudFormation can be used to automatically provision your AWS resources across multiple accounts and regions all from a simple text file. infrastructure-as-code-example. After we finish writing our script and creating our stack, our infrastructure will look like this: You can view or download the complete script from my Github repo. AWS CloudFormation generates a change set by comparing the current stack with your changes. All AWS Solutions Constructs are vetted by AWS, using best practices established by the AWS Well-Architected Framework. The condition will be used as a check when deciding on whether certain parts of our infrastructure should be built or not. We are going to keep things simple and have both NACL’s Engress & Ingress rules to ALLOW ALL, but we’ll have the definitions there in case we want to change things in the future. Kostas Gkountakos. From within the servers, there will be no limitations as they will be able to use all protocols and ports when reaching the internet. The first thing that should be clarified is the difference between “configuration orchestration” and “configuration management” tools, both of which are considered IaC tools and are included on this list. We start, by giving the user the option to define a range of IP addresses from which they can access the bastion hosts we will later create. How we wrote Infrastructure as Code (IaC) on AWS to help scale a start-up using Terraform and CloudFormation. We’ll then write the code for the AutoScalingGroup itself and have it use the above LaunchConfiguration. AWS : Write Infrastructure as Code using Cloudformation. Now there are many different technologies to do Infrastructure as code, and AWS CloudFormation is one example. Julio is a software engineer and works in developer relations for Amazon Web Services (AWS). Here is an example of how our Sensu monitoring stack is expressed in Cloudbank: It is now time to run the above file, monitor the sequence of events as resources are created, and test that everything will be working as expected. After we examine and we play around with the created infrastructure, we need to always remember to DELETE our stack, in order to destroy all created resources! For example, we could SSH into our bastion hosts and make a cURL request to any of our website instances to validate the installation of the web server and the correctness of the returned response. We need to be able to SSH into our bastion hosts from the SSHLocation (declared in Parameters), ping them, and we also need to allow HTTP access for the Application Load Balancer we’ll create later on.
