Using containers as the packaging mechanism allows teams to treat them as immutable infrastructure components. But if teams stick to the basic infrastructure as code principles, they'll be set up to successfully build and manage these modern, effective systems. Development principles that date all the way back to the beginning of Extreme Programming will provide the best guidance for making Infrastructure as Code into a blessing rather than a curse. Remember that this approach to infrastructure is optimized for change. When applied to infrastructure-as-code projects, this means teams can lint their configuration files and run unit tests on top of the code definitions to provide immediate feedback to the developer making changes. Once reviewed and merged to master, a pipeline job/agent picks up this change and tries to reconcile the state of infrastructure to what exists inside the version control branch. This doesn't work in a cloud environment where servers have to be configured and deployed on the fly. Principle 1 — imperative orchestration, declarative resource definitions. Example — you are deploying a VM, and you decide that a good naming convention is vm-{{region}}-my-domain. There is traction in the software engineering realm to test in production, even from an infrastructure view, because it is hard to replicate what happens in production inside a sandbox environment. These runbooks can be scripts, packages or modules (Bash, Python, PowerShell, etc. However, scripts are primarily used to automate a series of static steps that are repeated numerous times across multiple servers. Gone are the days where developers had to request hardware and wait for weeks for IT teams to procure, rack and stack it in a data center. Each principle drives a new logical view of the technical architecture and organizational structure. Reducing Shadow IT– Much of the shadow IT within organizations is due to the inability of IT departments to provide satisfactory and timely answers to operational areas concerning IT infrastructure and systems enhancements. Sign-up now. Define everything as code is obvious from the name, and creates repeatability and consistency. One common problem with Infrastructure as Code is that you often end up with a million variables that have to be configured. This new-age infrastructure is less costly to change, however. The only thing you should not hard-code are secrets, but in many cases you can dynamically generate them for non-prod environments where security is much more strict. This could get very verbose, too granular and hard to maintain. So the real idea behind infrastructure as code is: How do we take the process—in some sense, the things that we were pointing and clicking to achieve—how do we take that and capture that in a codified way? “Infrastructure as Code” (IaC) is another way that people talk about the same idea. Virtual clusters enable admins to deploy, track and manage containers across various systems to ensure performance, security and ... All Rights Reserved, You'll need the right set of knowledge,... Stay on top of the latest news, analysis and expert advice from this year's re:Invent conference. In any multi-tenant IT environment, noisy neighbors can be an issue. Example of declarative approach would be using Azure ARM templates or Terraform. Later, during another stage in the pipeline, teams can test these code definitions against a temporary sandbox environment and publish the results. An example might be northeurope for a region, or a GUID for default subscription where developers work. If you manage any of these modern infrastructure systems, you have a way to define your infrastructure blueprints in files and store them inside version control, such as Git. Infrastructure as code is one of the core philosophies of the DevOps culture, which aims to reduce friction and improve collaboration between different organizations and teams. Approach with Azure CLI will be discussed under Principle of “don’t be afraid of simplicity”. These providers also are keen to roll out support to define infrastructure in standard programming languages; examples include Pulumi and the AWS Cloud Development Kit. No change goes in once the application is packaged and deployed; every change (commit in version) creates an immutable artifact for later consumption. ), Jupyter notebooks, or markdown files. With IaC developers could reque… I am talking about idempotency of the script as a whole, it does not automatically mean that each little call in your script has to be idempotent, but the idempotency blocks (version boundaries) should be clearly defined. Build a DevOps feedback loop with these CI/CD tools, Weigh the pros and cons of outsourcing software development, Software development outsourcing throughout the lifecycle, Using the saga design pattern for microservices transactions, New Agile 2 development aims to plug gaps, complement DevOps, How to master microservices data architecture design, What the critics get wrong about serverless costs, How Amazon and COVID-19 influence 2020 seasonal hiring trends, New Amazon grocery stores run on computer vision, apps. However, in big majority of cases, this is not needed, or could be easily replicated with concurrency if your are using a “better” orchestration language like Python or Go. In this approach, I can look up all my connections. can be daunting. But putting their code in version control is just the first step in the journey -- this opens doors for other teams to see your code, contribute and collaborate. Changes made to these systems are frequent, and should be automated and placed under version control. Similar behavior can be observer with each complex Azure resources (e.g. I want to show some practices that worked well for us over last few years, with Azure as an example cloud platform (but the principles should be applicable to almost all forms of Infrastructure as Code). Topic becomes even more interesting when considering idempotency and reality when dealing with updates on a running production system, where it is not really a best practice to consider every possible parameter idempotent, but to define larger semantic blocks of idempotency as a whole. The IT infrastructure managed by this process comprises both physical equipment, such as bare-metal servers, as well as virtual machines, and associated configuration resources. In the years since companies have implemented IaC, a few have been able to master the art of doing it without much trouble. Having to install Visual Studio to deploy infrastructure is too big of a dependency. Once the changes are thoroughly tested, they can be packaged inside a versioned artifact and made available for later pipelines to consume and deploy infrastructure blueprints from them, i.e., continuous delivery. One example is that ARM templates creates resources in parallel in a DAG fashion using depends_on fields. It’s a process for managing tools like Puppet, Chef, Terraform, and Amazon’s Cloud Formation. Rather than manually making configuration changes or using one-off scripts to make infrastructure adjustments, the operations infrastructure is managed instead using the same rules and strictures that govern code development—particularly when new server i… Why go through all this effort when the change can be done via the click of a button in the UI? Continuously integrating, testing, and delivering each change enhances safety. Applicable infrastructure resources are virtual machines, networks, load … In the change management approach, user input is captured as a commit inside the version control -- remember to put everything inside version control, even the user input -- which is then raised as a pull request with an intent to merge to master. IaC outlines the principles and practices to address the following issues: Server Sprawl - Growth in the number of servers makes it Infrastructure as code (IaC from here on in) is a means by which engineers define the computer systems their code needs to run. One operator can deploy and manage one machine or 1,000 using the same set of code. Infrastructure as Code or IaC is short is the use of a descriptive model to manage different aspects of cloud infrastructure, including networks, connection topology, virtual machines, and others. Speaking of Azure, languages that we used for orchestration include Powershell, shell, Python and Golang. for a kubernetes cluster) can be automatically generated when script runs under a really powerful development user in development subscription, which is not a possibility in a production subscription where the service principal needs to pre-exist. Infrastructure as code is the automation of IT infrastructure. Testing builds confidence to deploy these changes safely. Basically, this means that your Infrastructure as Code can be executed multiple times always producing the same results, without errors on existing resources. Often, infrastructure teams add low-level tests for their declarative code, which becomes a pain to manage over time. For infrastructure artifacts, the next evolutionary stage in their lifecycle is the change management pipeline, which extends the software delivery pipeline mechanism to also deliver changes to the infrastructure. There is an exception to this principle, if you use some combination of encrypted secrets / configuration git tracking / GitOps, but this is out of scope of this article. Another problem is that declarative tools are starting to add imperative characteristics, like logical functions in ARM templates. As you start to roll out changes, document the failures and associated risks and ask yourself: Can we test for this risk before the deployment begins, to catch it early? Important advantage of imperative approach is implementation of control flow logic (like if, while etc.). IaC helps avoid configuration drift through automation, and increases the speed and agility of infrastructure deployments. Don't sweat the details with microservices. Now we have our code definition and a test suite that comes to life inside a CI/CD pipeline. IoTHub etc.). Here is an example: For me personally, this looks and feels horrible. Configuration management tools such as Ansible, Chef and Puppet support the ability to specify the tasks to perform on a deployed operating system in a file. In arithmetic, adding zero to a number is idempotent. Pacing with the changes and moving along the next generation of technology, IaC can make you catch the flight to success and advancement. IaC came into vogue with the ascension of AWS. In today's infrastructure landscape, almost every cloud platform and tool supports infrastructure as code or configuration as code. Multiple runs of the tool don't create multiple instances of the resource; instead it tries to converge the current state to the desired state. So, it’s obvious that there are a few wrong ways to implement IaC, and the end result of those ways is disaster. If you're starting out with validating changes, tackle the known risks from your test suite now; as your experience and confidence grow, organically develop into a test-in-production methodology. help you maintain uniformity and scalability while saving lots of time that you would waste if you did every task manually Teams should strive to put their operation runbooks inside version control as well. A single, unified API for automated infrastructure deployment. Infrastructure as Code is an IT infrastructure management process that applies best practices from DevOps software development to the management of cloud infrastructure resources.

Since change is inevitable in this new-age infrastructure, consider setting up a Kubernetes cluster in your cloud provider. As the example above shows, you will probably be done with Azure CLI approach in 2–3 minutes, and is much simpler to start with. Infrastructure as code (IaC) is the process of managing and provisioning computer data centers through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools. Version control automatically adds traceability, rollback and correlation to the changes made to the infrastructure. When it comes to cloud automation, there is a lot of choice out there. These types of reflective tests don't generate any value, as the tool that delivers the declarative configuration module also applies it. View Infrastructure as Code.docx from ECON 101 at Xavier School. First problem is, the line between imperative and declarative has become very very blurred when using tools such as Azure CLI or Python Azure library. These tools incorporate a foundational principle of modern IT infrastructure -- they are idempotent. Infrastructure as code principles: How IaC works and how to use it Once you have a basic understanding of infrastructure as code principles, it's time to focus on the steps to build a solid foundation for an infrastructure-as-code implementation. Cloud providers constantly add features requested by developers to their managed Kubernetes services, which means organizations constantly tweak it to best fit their needs. shell script / Powershell / Python) by calling the platform REST API directly (like https://docs.microsoft.com/en-us/rest/api/azure)/. In other words, only a few companies have succeeded in finding the right tactical strategy to fit the concepts of IaC into their structure. Moving secrets out of source code is a standard practice today. Infrastructure-as-code testing strategies to validate a deployment, Configuration management processes take down GRC challenges, Modernize Apps with a Single Architecture for VMs and Containers, Simplify Cloud Migrations to Avoid Refactoring and Repatriation. Don’t commit secrets in source control. The automation scripts needs to run on developer systems, on build agent in CI / CD pipeline, perhaps even in cloud; managing all the host systems for correct versions of python or powershell modules is simply toil, and you want to make sure that all environments are as equal as possible. This approach is faster and easier to integrate with other orchestrators (like CI / CD, run in docker etc.). Remember, the DevOps movement is about culture and transformation. Most of the system administration tasks were done manually or via self-written scripts. If the answer is yes, add it to the test suite. Declarative infrastructure would be equivalent to specifying resources in a JSON file and saying to a tool: “go do it however you like, but I want this state at the end”. Many teams that embrace this fundamental concept stop at this point. This has freed teams to iteratively change, learn and improve. For example, they set a disk size in a declarative configuration tool, such as Terraform, CloudFormation or ARM templates, and confirm that size in a low-level test, which asserts that the correct size is set. Let's debunk... AWS' annual December deluge is in full swing. There is a certain level of Organizational maturity needed to use these … For instance, a cloud deployment failed because of exceeded quotas. The new edition introduces three core practices for using Infrastructure as Code to make changes safely and easily. Infrastructure as Code is one of the key practices in DevOps. The version of the descriptive model mentioned above is the same as the one used in the source code … Updates, how to version the infrastructure and migrations are out of scope here, but the idea should be clear that you cannot simply rely on full idempotency down to the last property to always keep the production system running, and you will have a need for migration scripts, especially when dealing with stateful resources. https://docs.microsoft.com/en-us/rest/api/azure)/, https://blog.gruntwork.io/terraform-tips-tricks-loops-if-statements-and-gotchas-f739bbae55f9, https://github.com/DenisBiondic/DeviceCache.Containers/blob/master/Create-Infrastructure.ps1, Using Azure Monitor Logs with Azure Kubernetes Service (AKS), Using Terraform with Azure — the right way, How to backup Azure Blob storage accounts, Bootstrapping Azure Cloud to Your Terraform CI/CD, Provisioning Azure Cosmos DB resources with Terraform, Infrastructure as Code with Azure Blueprints and is it a Terraform Alternative, Creating a DevOps Pipeline to deploy Docker Containers using Azure Kubernetes Service and…. We can add a load balancer with a single API call to the cloud provider, rather than procure and install additional hardware. Developers used to think it was untouchable, but that's not the case. The GitHub master branch is no more. Infrastructure as Code (IaC) is a method to provision and manage IT infrastructure through the use of source code, rather than through standard operating procedures and manual processes. Navigating this world of cloud providers, containers and container orchestration, service meshes, serverless, etc. Wikipedia defines IaC as follows: Infrastructure as code is the process of managing and provisioning computer data centers through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools. This practice is often referred to as GitOps and is gaining momentum with projects like Flux for Kubernetes. Since fluid resources are now served … Be open to pull requests in other repositories maintained by other teams and individuals. Writing tests for infrastructure is a learning process, and teams can build iteratively upon them. As the name suggests, infrastructure as code is the concept of managing your operations environment in the same way you do applications or other code for general release. To make this name unique, you simply add an environment tag which is basically the single mandatory parameter to the automation script, so that you end up with something like the following (env-tag: dbio as in my personal dev environment): vm-northeurope-dbio-my-domain. Adding these artifacts inside version control gives the entire team visibility into the code used to provision infrastructure. Ideally, infrastructure teams can author a test that checks before the deployment begins, to catch the risk of failure. Infrastructure as Code is shifting organizational apparatuses to accelerate processes, document infrastructure and maintains consistency in the policies to minimize error and maximize money in no time. It leverages agile engineering tools and practices to provision and manage highly reliable infrastructure at speed. The concept of infrastructure as code is similar to programming scripts, which are used to automate IT processes. To achieve this, build artifacts with a versioning scheme such as semantic versioning. Amazon's sustainability initiatives: Half empty or half full? Convention over configuration goes only so far, there are some variables that you simply need to provide, like the region for example. An approach which many projects take is to have ARM templates implemented directly in Visual Studio, and then using the wizard to execute the code: There is no need for this. Infrastructure as code allows virtual machines to be managed programmatically, eliminating the need for the manual configuration of, and updates to, individual pieces of hardware.This makes infrastructure highly "elastic,” i.e. Infrastructure as Code (IaC) is the management of infrastructure (networks, virtual machines, load balancers, and connection topology) in a descriptive model, using the same versioning as DevOps team uses for source code. While critics say serverless is an expensive, clunky way to deploy software, it really isn't -- if you use it right. Ideal simplistic interface when starting with a project is to have a script in the root of the project to deploy the infrastructure. Shadow IT poses significant security risks as well as potential unforeseen costs for the organization. However, there is still a risk that the deployment fails at the final stage where it tries to deploy. Infrastructure as Code is the "A(utomation)" in the DevOps "CALMS" model. Imagine that an engineer changes something in the version control repo, and before these changes are deployed the validations within a CI/CD system warn of a potential issue solely because of the test suite validating incoming changes. Essentially, don’t be afraid to use the simple approach like with Azure CLI, you still get to use more complex approach down the road if you need it. Rather than relying on manually performed steps, both administrators and developers can instantiate infrastructure using configuration files. Instead of making all such parameters mandatory, simply hard-code the default value in the script itself. Here is an example of creating a virtual network using Python Azure SDK: Both ARM template and Python example are idempotent and basically declarative, although most people would call Python approach an imperative approach. Instead, check that the configuration is actually applied at this stage -- if the configuration is applied, the desired state must be met. Why make that effort to test changes to infrastructure? Infrastructure as code is sometimes referred to as programmable or software-defined infrastructure. Example with ARM template: In terms of features, there is some really cool stuff with ARM templates, Terraform and Ansible. Infrastructure as code is a declarative model for defining what your infrastructure is going to look like. And this code can help you configure and deploy these infrastructure components quickly and consistently. Privacy Policy Most commonly, these engineers utilize a framework like Chef or Ansible or Puppet to define their infrastructure. Infrastructure as Code (IaC) brings automation to the provisioning process, which was traditionally done manually. Simple solution is to use a naming convention for all resources, and to isolate them by providing a unique tag which will be used in each name. DevOps is the combination of cultural philosophies, practices, and tools that increases your organization’s ability to deliver applications and services at high Instead of considering each setting “idempotent”, it is perfectly fine to deploy the cluster with a simple Azure CLI call, and organize updates on production system in better suited migration scripts. We touched on the topic of idempotency in previous section. A common problem with all software is to have the right dependencies, and with infrastructure as code same problem persists. Today's technology world is changing at unprecedented speeds. This is the exact approach Azure CLI takes, and that is why this command is so short: az aks create -g MyResourceGroup -n MyManagedCluster, altough we are creating a whole cluster with several VMs, a load balancer etc. Like the principle that the same source code generates the same binary, an IaC model generates the same environment every time it is applied. This script can be executed simply as: Side note: part of subscription selection is missing in the script, and would have to be done manually once with Select-AzureRmSubscription, but this could be added to the script as well with default subscription as default parameter. The lifecycle for infrastructure as code or configuration as code is not over yet, because the blueprints are tested and packaged but they don't do anything fruitful for an organization until they actually deploy infrastructure. As far as definitions go, this one isn’t bad, but it’s somewhat wordy. A comprehensive guide. If there is a failure down the stages, it can be tied back to a change that was introduced. This approach reduces operational overhead and risk to manage or change infrastructure. During these stress tests, it is critical monitoring all the components of the system to identify whether there is any bottleneck. Can container tools box out configuration management? IaC is a way to manage infrastructure and all its bits and pieces — networks to VMs to load balancers — into a single source of truth about an environment. What in the world is Infrastructure as Code? It also can hook to CI/CD pipelines to automatically trigger action for a change introduced. Here is an example where Powershell is used to orchestrate multiple ARM templates, including a conditional deployment depending on a parameter: https://github.com/DenisBiondic/DeviceCache.Containers/blob/master/Create-Infrastructure.ps1. The core idea behind a software-defined data center(SDDC) is that all the physical resources that make up the data center can be abstracted through software. Copyright 2016 - 2020, TechTarget They’re not, and there’s a reason we have two distinct terms.IAC is a process for managing infrastructure. Data mesh addresses these dimensions, founded in four principles: domain-oriented decentralized data ownership and architecture, data as a product, self-serve data infrastructure as a platform, and federated computational governance. Turning a physical data center into software makes it infinitely easier to quickly compose and then roll out environments based on software defined building blocks of compute, storage, and network. Enabling a fast response to new IT requirements through IaC assisted deployment not only assures higher security and … As we discussed here, IAC has its own set of responsibilities and practices.Configuration as code is a process for managing application configuration data. Teams must determine how to validate changes and their results safely and without affecting production environments.

The Sustainable Development Goals are a call for action by all countries – poor, rich and middle-income – to promote prosperity while protecting the planet. Let’s say we want to deploy a AKS cluster in Azure. An idempotent operation can be repeated an arbitrary number of times and the result will be the same as if it had been done only once. Infrastructure as code is one of the core philosophies of the DevOps culture, which aims to reduce friction and improve collaboration between different organizations and teams. In this article, I am focusing on inital IaC scripts (aka Day 0 operations). Historically, infrastructure such as servers were deployed and managed by specialists who configured things manually. What is configuration management? example -> service principal (e.g. Providers' tools, such as AWS CloudFormation, Azure Resource Templates and HashiCorp Terraform, have a domain-specific language to declaratively define the end state of what the infrastructure looks like.
