For example, if a zero-day vulnerability is discovered, all servers with the same configuration must be updated. Infrastructure can't be changed while it's in place.

In a multi-threaded context, safe thread code means mutation is almost non-existent.Predictable state due to the fact that the infrastructure is never changed, which reduces complexity.Testing is made easier by the uniformity of setups across several servers.

Each new server or virtual machine may be tracked by the IT department as it is deployed. Tracking and rollbacks are significantly easier with discrete versioning.There is no configuration drift because there are no adjustments to make.Immutable infrastructure is based on this concept, which you can implement with the help of technologies like Packer.‌‌ Benefits of Immutable Infrastructure Now, from the use-case in mutable infrastructure, instead of configuring the server after deployment, how about configuring it before deployment, like in the mutable infrastructure above? ‌‌Making your infrastructure immutable is the best way to ensure scalability in the realm of IaC.‌‌ This makes your product more consistent and reliable. In immutable infrastructure, components are recreated and replaced rather than updated after they're formed. Due to these unexpected situations, debugging is tough.įortunately, you can employ immutable infrastructure to avoid the issues that mutable infrastructure can cause. If updates aren't applied correctly, there's a higher danger and complexity in production workloads.

Update failures happen more often because of a range of unanticipated factors such as network connectivity, unresponsive repositories, DNS downtime, and so on.

Server changes aren't always recorded, making version tracking more complex.

Because you have to manually configure the servers, provisioning servers is frequently a lengthy procedure.

Because each server has a unique configuration, which is known as configuration drift, technical difficulties are difficult to diagnose or reproduce.

The infrastructure can be tailored to the exact requirements of the server-side applications.

Updates are usually quicker and can be tailored to each server individually.

Rather of having to build a new server from the ground up, IT staff gets to know each server on a "personal" level, allowing them to diagnose issues more quickly. It follows the BUILD, DEPLOY, CONFIGURE pattern. This is referred to as mutable infrastructure.

This is fantastic for a few servers, but for many servers, it can result in application mismatches unless you use configuration tools like Ansible. We manually or automatically change the server whenever a new upgrade/configuration to the application is required.

We configure the program to install all necessary instructions and configurations after deployment in order for it to be production ready. ‌‌Let's say we have a web application that we want to deploy to the cloud or to an onsite server. You can log into servers, apply fixes, update configurations, and more. You can change and configure infrastructure that is mutable depending on your needs. Types of Infrastructure What is Mutable Infrastructure? The core concept is that you define, deploy, update, and destroy your infrastructure (servers, databases, networks, configuration, and so on) by writing and executing code.

‌‌Infrastructure-As-Code ( IaC) refers to the process of managing and supplying infrastructure using code rather than manual methods. In this article I will explain the concepts behind Infrastructure-As-Code ( IaC) at a high level and dive into a category of IaC known as server templating.įor the purpose of this article, we will be using a server templating tool called Packer to create a custom Amazon Machine Image (AMI) and use it to launch an AWS EC2 instance. Hey everyone! If you're wondering what infrastructure-as-code means, then you've come to the right place.
