We refer to this as infrastructure as code. So..."Envirocation," anyone? Everything on the canvas can be modified by editing the code, and while the graphical interface can configure most of the options, some more advanced blueprint features will need to be created using the code editor. If the code is not written according to the rules of the programming language, applications cannot be created. IaC ensures safer and efficient change management within various devices, platforms, and systems. This paper describes the benefits of Infrastructure as Code, and how to leverage the capabilities of Amazon Web Services in this realm to support DevOps initiatives. Email or phone. Through a combination of dragging-and-dropping components onto the canvas, editing the code directly, and using the properties and inputs editors, you can build out more complex multi-tiered applications, such as the one shown below. Consequently, DevOps has evolved to include Infrastructure as Code (IaC) frameworks to fulfill this need. The Fulfillment Engine knows how to communicate with the various infrastructure endpoints – typically IaaS, CaaS or PaaS. In this second part (and the related webinar) we focus in on the Infrastructure as Code aspect of DevOps, how vRealize Automation implements Infrastructure as Code, and how you can use Infrastructure as Code to improve the reliability, increase the speed of development, reduce failures and fix problems more quickly. DevOps: Culture – Collaboration, Empowerment, Autonomy, Automate IT: Make Private Cloud Easy Hands-On Lab. Two leading examples of IaC systems are: CloudFormation, which comes as part of Amazon Web Services (AWS) blog post and webinar for this DevOps for Infrastructure series, Infrastructure as Code and vRealize Automation, get started with the vRealize Automation Terraform Provider, Virtualizing Business Critical Applications, The ability to roll back to a previous configuration with confidence, Maintaining environments a different versions, Self documenting – commit messages document what’s changed, who changed it and why (ideally! A fundamental principle of DevOps is to treat infrastructure the same way developers treat code. vRealize Automation offers a “low code” approach to getting started with Infrastructure as Code – that is, the Blueprint Designer within the platform provides a palette of components that can be dragged onto a design canvas. Code is stored in a version management or source control system that logs a history of code development, changes, and bug fixes. Today, cloud providers have changed the way we manage infrastructure and DevOps has changed the way we develop and deploy software. For now, I will grab a copy of the YAML code and delete this manually created blueprint. It gives the ability to reuse, version and test infrastructure as with any regular code. Final thoughts on Infrastructure as Code DevOps principle. Delighted to announce that my free training course on DevOps: Infrastructure As Code with Azure has just released on the Microsoft Open edX platform. DevOps Training Video | Infrastructure as Code Explained | DevOps Tutorial for Beginners - Part 5https://goo.gl/o768rnHello Everyone! In a sense, this is the same thing DevOps is doing with the staff in charge of these two worlds, melding developers and operations staff into a single entity with a portmanteau of a name. Infrastructure as Code has emerged as a best practice for automating the provisioning of infrastructure services. Press question mark to learn the rest of the keyboard shortcuts - It's a completely programmatic approach to infrastructure, that allows us to leverage development practices for our systems. When you edit the YAML directly, there’s intellisense-like code completion to help complete the properties of an object – the screenshot below shows the properties of a load balancer being build out, with suggestions in a dropdown. To meet these challenges, you can automate deployments and use the practice of infrastructure as code. I’ve created a new folder in my local copy of the git repository, and created a new file called “blueprint.yaml” with the code. I can manage the git repository using the Visual Studio Code plugins, or by using git commands. Continuous integration and continuous delivery (CI/CD) are essential practices of DevOps that automate the processes and create a faster release cycle. Automation remains at the core of the DevOps philosophy, eliminating manual processes and introducing smarter tools to enable frequent delivery pipeline. Infrastructure as Code (IaC) is being widely accepted as the way forward to implement infrastructure. Adopting IaC results in less complexity and faster set up. Projects can be mapped to a specific branch within a repository, allowing for the promotion of code through environments using GitOps methodology. Save my name, email, and website in this browser for the next time I comment. Infrastructure as code (IaC) is undoubtedly changing how engineers approach the cloud. Are you going to level up your IT infrastructure with IaC? But changing the underlying OS would require the server to re-deploy. Press J to jump to the feed. You can use machine-readable files to set up required IT infrastructure to test and run your code. Just like the application code, you store the infrastructure code in a source repository and version it. Dedicated full-time resources were required to manage servers and their availability 24/7 to run a business without any trouble. Put simply, IAC is the practice of managing the infrastructure using code. The YAML will be used to add the blueprint to the Git repository later. Consequently, DevOps has evolved to include Infrastructure as Code (IaC) frameworks to fulfill this need. Improved system performance: IaC assures risk prevention by providing timely awareness on concerning areas. By doing so, infrastructures can be created quickly, consistently, and repeatedly. Here are some points worth paying attention to: A few years ago, software development and delivery were totally different. … AWS CloudFormation). Marketing Blog. In simple terms, IaC is a framework that takes proven coding techniques and extends them to your infrastructure directly, effectively blurring the line between what is an application and what is the environment. Also, it ensures compliance and safety of IT infrastructure along with the faster response to issue/requirements. What is infrastructure as code in DevOps and why does it matter? Application code has a defined format and syntax. I then used the “git commit -m “IaC Webinar”” command to commit those changes to my local git repository with a commit message of “IaC Webinar”. That was the time when system administrators had to ensure the server availability to run business-critical apps smoothly. Infrastructure as Code (IaC) is one of the key enablers of the DevOps revolution. DevOps Move fast without breaking infra or apps SecOps Enforce policies that accomplish cloud governance projects of all kinds Engineering Leaders Bring teams together to run secure and resilient cloud-native infrastructure This is a fully remote role, based within the UK, with a six-12 month anticipated duration. DevOps consists of many terms, processes, methods, and concepts that are dedicated to making software development faster, efficient, and secure. Software Development News. According to the definition by Microsoft, “Infrastructure as Code 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”. Due to frequent delivery and faster deployment, manual way of managing infrastructure often resulted in troubles and therefore, slower deployments. Often, they needed to take care of version controlling, time zones, load balancing, interlinking, installment of necessary software packages, and other settings. In code, you define the infrastructure that needs to be deployed. In this second part (and the related webinar) we focus in on the Infrastructure as Code aspect of DevOps, how vRealize Automation implements Infrastructure as Code, and how you can use Infrastructure as Code to improve the reliability, increase the speed of development, reduce failures and fix problems more quickly. See the original article here. Also, this method makes DevOps adoption easier by streamlining development and deployment processes. I’ve also  blogged previously about Infrastructure as Code and vRealize Automation and how you can get started with the vRealize Automation Terraform Provider. Once the repository has synchronised with Cloud Assembly, the new Blueprint is available. Different versions of the same blueprint are mapped to their respective projects from their associated git branches, as the Blueprints view below shows: With the Git integration configured, you can now manage your blueprints as code using your editor of choice, and everyday git commands. Together, the Variables and Definition describe the desired Infrastructure State in a well-defined format – whether that’s a Domain Specific Language (e.g. IaC is closely related to DevOps. Join the DZone community and get the full member experience. Scalable infrastructure: It offers organizations a great benefit of scalability. Overall customer satisfaction: Apart from saving your cost and time, it ultimately improves customer satisfaction due to the ability to deliver faster services at affordable costs. If you’re unfamiliar with the git command line, you can also achieve the same thing using the Source Control tab of Visual Studio Code. IaC uses software with a domain-specific language , interpreter, execution environment and external interfaces to build on traditional script-based management techniques. For example, I used “git status” to see that there were untracked files in my git repository – these are my IaC Webinar folder and the blueprint.yaml file. Opinions expressed by DZone contributors are their own. Thanks for reading this, I hope it gives you a good introduction into some of the basics of infrastructure as code, and how you can use vRealize Automation to start managing your infrastructure using those principles. Simplifying this, Infrastructure-As-Code is one of the prerequisites for DevOps implementation in your organization and it treats IT infrastructure as software. Switching to IaC requires efficient change management from scratch and knowledge to use tools. Different environments for development, test, and production must be consistent to avoid any issues during deployment. Over the years, backend management has changed fundamentally. Finally, I use “git push” to synchronise those changes with my remote (GitHub) repository. DevOps Toolchain But, in addition to automating application and platform, agile development can be further facilitated through the use of automation in infrastructure management, that is, through infrastructure agility. Infrastructure as code is the prerequisite for common DevOps practices such as version control, code review, continuous integration and automated testing. Infrastructure as code (IaC) allows you to describe IT infrastructure such as servers, networks, databases and operating systems as code. Virtualization of hardware makes it easy to add additional resources, replacing those, and scaling whenever required. Just a few years ago, the server used to occupy rooms and floors. As CI/CD, IaC is considered one of the key practices of DevOps. Over a million developers have joined DZone. DevOps Automation Engineer / AWS / Infrastructure as Code ... Sign in to save DevOps Automation Engineer / AWS / Infrastructure as Code at Motion Recruitment. How Infrastructure-As-Code (IaC) Is Related To DevOps As CI/CD, IaC is considered one of the key practices of DevOps. Published at DZone with permission of Ankit Kumar. These two revolutionary concepts brought some significant changes in software development space. Changes to the Variables or Definition will be processed by the Fulfillment Engine to update the Infrastructure State – depending on the mutability of the infrastructure and the type of change, that might mean re-deploying or modifying the deployment, for example, changing the number of web front end servers in a cluster would likely just deploy or remove a front-end web server. As its name suggests, it treats infrastructure setup as code rather than a manual process to configure hardware and systems. Anyone on your team can run the code and deploy similar … Best Practices for Infrastructure as Code: Best Practices. The fundamental purpose of DevOps is to achieve agility in development while staying focused on product quality. Hola Mundo, I wrote a blog post about - Infrastructure as Code with terraform for multiple environments Let me know if you have any questions! The “Low Code” approach allows blueprint designers to quickly build out the YAML required and learn the structure of the code until they’re more familiar with it. vRealize Automation Projects can be configured to provide one-way synchronization from a Git repository, allowing the release of new blueprint code directly from source control. There were different roles like system administrator, database administrator, developer, tester – all needed to work in harmony to deploy software on the production environment. You can run this code to build and configure your infrastructure automatically. With the basics of IaC covered, it’s currently time to consider some best practices for Infrastructure as Code that will be the critical factors in DevOps. Over the years, the cloud has promoted "hardware virtualization," in which you don’t need to manage infrastructure; instead, cloud providers like Amazon, Google, and IBM manage your infrastructure and offer flexibility and scalability. Infrastructure-As-Code enables software delivery at high velocity by fulfilling all IT related requirements. Experity - the healthcare software provider - is hiring a contract DevOps Engineer to design and implement fully automated CI/CD pipelines on AWS and to lay the foundations of infrastructure as code. In the diagram below there are two blocks in the “Infrastructure as Code” section – this is typical of any IaC implementation – code that defines variables, and a definition of the desired infrastructure state. The infrastructure code becomes part of your project. These practices provide continuous delivery of quality software that meets the requirements set. Once a Git Integration endpoint has been added, Projects can be configured to synchronise with the intended branch – for example, in the image below the Development project is synchronising with the development branch of my vra-cloud-blueprints repository. If you think of DevOps as a train, infrastructure is the track that the train runs on. Infrastructure is an integral part of the software development that acts as a backbone for the whole system. Change management: Before you deploy software on the production environment, the code is frequently altered and tested. You can go back and watch the Part 2: Demystifying Infrastructure-as-Code webinar that this post is based on here https://bit.ly/vRAIaC, Your email address will not be published. Documentation is the most detested part while maintaining an infrastructure. It drastically reduces the overhead and significantly contributes to faster software delivery. I then use “git add .” to add all of the untracked files (or I could swap the “.” for the path to the files I want to add). The technique uses practices familiar with software development, whereby the infrastructure is codified into templates or defined in code. IAAC( Infrastructure As A Code) Infrastructure as code helps to deploy the software faster in multiple servers, avoid inconsistencies of software versions in the servers, increases productivity and lower costs. When we talk about a faster release cycle, there is always a need for faultless infrastructure components that can facilitate provisioning the required test and production environment. Hence, for organizations who are using DevOps in their development environment, IaC offers great benefits. HCL for Terraform) or a more generic language such as JSON or YAML (e.g. Together with cloud automation technology, It provides the ability to turn complex systems and environments into a few lines of code, which can be deployed at the click of a button. Required fields are marked *. IaC is also used to represent the process of cloud implementation of the physical environment (refer to this article here). Server management no longer requires full-time administration and several hours to configure it, thanks to the cloud and DevOps. In my first blog post and webinar for this DevOps for Infrastructure series, we talked about how the overall DevOps cycle and how vRealize Automation can facilitate DevOps for Infrastructure. DevOps, Infrastructure as Code, and PowerShell DSC: The Introduction; DevOps is the new cool thing (at least in the Windows world) everyone is talking about and the IT professionals (some of us at least) just give a blank stare every time the DevOps discussion comes up. Speed: In today’s time, the speed at which software is delivered/upgraded rated as one of the significant factors behind the success. [ Robotic Proces… IaC, when coupled with dev tools and automation, opens up new avenues for infrastructure performance, scalability and, now, security. by magnitia / On December 10, 2019 / In Devops Training. 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 … IaC is an essential part of DevOps transformation, helping the software development and infrastructure management teams work in … As more components are added to the blueprint, the YAML code is built out. All of this is done on the staging branch of my repository, which maps to the Staging project in Cloud Assembly. Let’s start with what I’ve termed the mechanics of infrastructure as code – how Infrastructure as Code actually works – what are the components, and how do they work together to achieve the desired outcome. The other concept that has changed the way infrastructure is managed is DevOps. These teams expect to provision multiple test environments reliably and on demand. The visual representation that is shown in the design canvas is actually rendered from the code – the blueprint itself is YAML code – in the code pane to the right hand side of the canvas. Your email address will not be published. At this point, it’s worth re-iterating that Application State is not necessarily the same as Infrastructure State, so it may be necessary to employ methods such as Green/Blue deployments, migrations, or retrieving remote Application State from within the deployment to ensure that changes do not affect availability. And it is also true that you are not going to set up a server the way it was maintained years ago. Here are some best tools through which you can implement provision infrastructure in your organization: Ansible – popular configuration management tool. One of the big things in DevOps is “infrastructure as code.” This means that you treat your infrastructure the exact same as you would treat your application code. Below I’m using Visual Studio Code with it’s inbuilt Git integrations to add the blueprint YAML we created earlier in the blueprint editor. Infrastructure as Code enables DevOps teams to test applications in production-like environments early in the development cycle. The training has hours of video content, theory, labs and certification. A number of tools are available to adopt IaC and organizations who have adopted it have found it beneficial. Here are some challenges of IaC that are roadblocks in IaC adoption: Risk of outside intervention after set up leads to trouble, Require humans to audit whole IaC setup periodically, This concept requires efficient planning and faultless execution to achieve results, Collaboration is a crucial trait to implement this concept, Required a unified approach to adopt Infrastructure-As-Code. Put simply, Infrastructure-As-Code (IAC) is a concept that represents modern practices of managing infrastructure (data servers, storage, and networking requirement). The Fulfillment Engine translates the generic definition provided by the code into a specific infrastructure deployment and state. ). Defining the infrastructure as code enables these definitions to be managed using techniques that traditional developers use to manage their code. Infrastructure as Code is an automation technique used to provision infrastructure. Infrastructure-As-Code: A DevOps Way To Manage IT Infrastructure, Developer Here, in this post, we are talking about one such revolutionary topic, Infrastructure-As-Code (IAC) to help you understand software-defined infrastructure. "Infrastructure as code" may not be as catchy as "DevOps." A software is built and tested and then deployed on a physical server along with necessary requirements to run that particular software. With the rise of DevOps and cloud computing, IaC can offer great benefits of consistency and reliability to the organization but it still depends on the requirements and the right skill set. There is a variety of tools available to help you adopt IaC with the right mindset and skills. This whole server management and environment set up would require lots of hours and there would be chances of human errors that would impact the live environment, resulting in errors and slower deployments. With IaC, you can deploy faster with reliability because there is no need to manually handle and reflect the state of your infrastructure in various environments. These frameworks provide declarative management of resources, thereby removing tasks such as typing commands in in command line interfaces (CLIs) and configuring infrastructure manually. Some of the tools are powered by giant cloud providers and some of them belong to DevOps tools providers. Infrastructure represented as code can also be validated and tested to prevent common deployment issues. You can strategically plan this kind of tech stack and capitalize on it to improve business performance. Infrastructure as code is a DevOps practice in which IT operations admins codify the underlying infrastructure of their production environment as software. Treat infrastructure resources and configuration parameters as programmable objects, and control them via code -- a concept known as infrastructure as code . They can be edited with any text editor, and managed within a Source Control system such as Git, with all of the advantages of tightly controlled versioning – including, but not limited to: The code is processed by a Fulfillment Engine, which is responsible for taking the code definition and implementing it. Get rid of documentation. Just like continuous integration and delivery, this concept automates the process of setting up infrastructure components to increase software release speed. Therefore, slower deployments implement provision infrastructure achieve agility in development while staying focused on product quality in organization.
