Why Utilizing IaC Alone is a Half-baked Infrastructure Technique


The shift to a developer-centric imaginative and prescient of infrastructure that began about 15 years in the past provided customers frequent updates and a approach to simplify API-centric automation. Infrastructure as Code (IaC) grew to become the usual methodology for software program builders to explain and deploy cloud infrastructure. Whereas on the floor, having extra freedom feels like a virtually utopian situation for builders, it has grow to be a nightmare for operations groups who at the moment are tasked with understanding and managing the infrastructure and the underpinning instruments within the DevOps toolchain. As cloud infrastructure grew to become commoditized, new limitations emerged alongside the broader adoption of IaC, limitations that may have unfavourable impacts for the general enterprise.

When you consider software environments like a pizza (or in my case, a vegan pizza), IaC is simply the unbaked dough, and the person IaC information alone are merely flour, salt, yeast, water and so forth. With out the opposite needed elements like the info, community topology, cloud companies and atmosphere companies – the toppings, if you’ll – you don’t have an entire atmosphere. Moreover, the necessity for correct governance, price controls, and improved cross-team collaboration has grow to be much more important. 

Whereas the wants of builders are application-centric, IaC is infrastructure-centric. There’s a disconnect between the expectations of the event and operations groups that creates delays, safety dangers, and friction between these two groups. For IaC for use successfully, securely and in a scalable method, there are some challenges that must be addressed.

Let’s focus on the highest 4 challenges of IaC and the way developer and DevOps groups can overcome these ache factors and obstacles utilizing Environments-as-a-Service (EaaS).

Integrating IaC property 

Certainly one of at the moment’s central challenges is in producing a pipeline that gives a approach to deploy infrastructure property repeatedly and persistently. Many DevOps organizations are sitting on high of mountains of IaC information, and it’s a monumental process for these groups to grasp, monitor and deploy the fitting infrastructure for the fitting use case. 

EaaS solves this drawback by automating the method of discovering, figuring out, and modeling infrastructure into full, automated environments that embody all the weather that the tip consumer requires. 

Moreover, EaaS options get rid of the appliance atmosphere bottleneck and allow quicker innovation at scale by defining parts in modular templates, in any other case generally known as “blueprints,” and assist organizations handle the environments all through the complete software life cycle. Current IaC scripts can simply be imported and managed in an infrastructure stack, or customers can select to construct “blueprints” from scratch. 

Distributing the fitting environments to the fitting builders

Utilizing the mistaken atmosphere definitions in numerous levels of the SDLC is like utilizing a chainsaw to slice your pizza; it gained’t get the job carried out proper and will create extra issues. It’s essential for builders to have entry to correctly configured environments for his or her use case. Builders don’t essentially have the experience to correctly configure environments. But, in some circumstances, they’re anticipated to, or they try to do it as a result of there aren’t sufficient folks of their group with the cloud infrastructure expertise to take action in a well timed method. The consequence might be an atmosphere that’s horribly misconfigured like placing sauce on high of your pizza (sorry, Chicago) and even worse, pineapple and ham (not sorry).

Organizations ought to distribute full environments to their builders with “baked-in” elements and customised insurance policies and permissions. To perform this, most EaaS options have the power to offer a self-service atmosphere catalog that simplifies this course of, whereas additionally dramatically decreasing provisioning instances. Operations groups can reap the benefits of role-based insurance policies, so builders have entry solely to the environments which can be acceptable for his or her use case, making certain consistency all through the pipeline.  Consumption of this service ought to be accessible through command line or API, so it might seamlessly combine into your CI/CD pipeline.

Managing the atmosphere life cycle & controlling prices 

The orchestration of environments is just one piece of the pie. It needs to be served, consumed, after which, in fact, you need to clear up afterward. Along with configuring and serving up the fitting environments for the builders to eat, EaaS permits for seamless enforcement of coverage, compliance, and governance all through the complete atmosphere life cycle, offering info on how infrastructure is getting used. Throughout deployment, finish customers can set the environments for a specified runtime, automating teardown as soon as sources are now not required to make sure the leanest attainable consumption of cloud sources. 

Everyone knows there’s no such factor as a free lunch, so understanding and managing cloud useful resource prices is a vital component of the complete atmosphere life cycle and demonstrates the enterprise worth of an organization’s infrastructure. By leveraging auto-tagging and custom-tagging capabilities, companies can simply monitor how environments are deployed in a centralized manner, offering full operational transparency, and making certain sources are being provisioned according to a company’s prescribed requirements. Understanding the enterprise context behind cloud useful resource consumption permits companies to optimize prices and higher align these bills with particular tasks, functions, or improvement groups.

Making a dependable IaC infrastructure 

There are a number of important steps to make sure infrastructure reliability. This consists of depositing IaC code right into a supply management repository, versioning it, working exams towards it, packaging it, and deploying it in a testing atmosphere – all earlier than delivering it to manufacturing in a secure, safe, and repeatable method. 

In sustaining a constant and repeatable software structure, the target is to deal with IaC like every software code. You possibly can meet the altering wants of software program improvement by making a steady IaC infrastructure pipeline that’s interwoven with the software program improvement and supply course of, leveraging greatest practices from software program supply, and transposing them to the infrastructure supply course of.

To make sure that your infrastructure is dependable, you will need to think about the bigger image. IaC has grow to be ubiquitous and has definitely superior infrastructure provisioning, however that’s the place it ends. Organizations want to start out serious about not simply configuring and provisioning infrastructure however managing the complete life cycle of full environments to understand the true worth of infrastructure. Identical to you wouldn’t go to a pizza parlor and order a blob of uncooked dough, you wouldn’t serve your builders simply the infrastructure – they want the entire atmosphere.

Utilizing EaaS, builders are in a position to obtain their mission targets, help the complete stack, combine IaC property, and ship complete environments wanted to orchestrate the infrastructure life cycle. Buon appetito!
