AWS CloudFormation vs Webpack: What are the differences?
Introduction:
In this comparison, we will highlight the key differences between AWS CloudFormation and Webpack - two popular tools for managing and deploying applications in the cloud.
Infrastructure as Code vs. Module Bundler: AWS CloudFormation is primarily used for defining and provisioning the infrastructure resources in a declarative manner using templates, known as Infrastructure as Code (IaC). On the other hand, Webpack is a module bundler that focuses on bundling JavaScript and other assets for web deployment.
Deployment and Orchestration vs. Code Optimization: AWS CloudFormation facilitates the deployment and orchestration of complex cloud environments by defining resources and their dependencies. In contrast, Webpack specializes in optimizing client-side code for performance and bundling multiple assets together to enhance the loading speed of web applications.
Cloud Resource Management vs. Frontend Build Tool: CloudFormation is more suitable for managing cloud resources like EC2 instances, S3 buckets, and RDS databases in AWS. Meanwhile, Webpack is a frontend build tool that helps developers bundle, minify, and transform front-end assets like JavaScript, CSS, and images for deployment.
AWS Ecosystem vs. JavaScript Applications: AWS CloudFormation is closely integrated with the AWS ecosystem, allowing users to create, update, and delete AWS resources easily. Conversely, Webpack is commonly used in JavaScript ecosystem to bundle modules and assets for building modern web applications.
Declarative vs. Programmatic: CloudFormation templates are written in JSON or YAML format and follow a declarative approach to define resources and their configurations. In contrast, Webpack configurations are written in JavaScript and offer more flexibility and programmability to customize the build process according to specific requirements.
Automated Infrastructure Provisioning vs. Code Optimization: AWS CloudFormation enables automated provisioning of infrastructure resources based on templates, ensuring consistency and repeatability. On the other hand, Webpack focuses on optimizing code for performance and efficiency, enhancing the overall user experience of web applications.
In Summary, AWS CloudFormation is designed for managing cloud resources through Infrastructure as Code, while Webpack is a module bundler and optimization tool for frontend assets in web applications.
Because Pulumi uses real programming languages, you can actually write abstractions for your infrastructure code, which is incredibly empowering. You still 'describe' your desired state, but by having a programming language at your fingers, you can factor out patterns, and package it up for easier consumption.
We use Terraform to manage AWS cloud environment for the project. It is pretty complex, largely static, security-focused, and constantly evolving.
Terraform provides descriptive (declarative) way of defining the target configuration, where it can work out the dependencies between configuration elements and apply differences without re-provisioning the entire cloud stack.
AdvantagesTerraform is vendor-neutral in a way that it is using a common configuration language (HCL) with plugins (providers) for multiple cloud and service providers.
Terraform keeps track of the previous state of the deployment and applies incremental changes, resulting in faster deployment times.
Terraform allows us to share reusable modules between projects. We have built an impressive library of modules internally, which makes it very easy to assemble a new project from pre-fabricated building blocks.
DisadvantagesSoftware is imperfect, and Terraform is no exception. Occasionally we hit annoying bugs that we have to work around. The interaction with any underlying APIs is encapsulated inside 3rd party Terraform providers, and any bug fixes or new features require a provider release. Some providers have very poor coverage of the underlying APIs.
Terraform is not great for managing highly dynamic parts of cloud environments. That part is better delegated to other tools or scripts.
Terraform state may go out of sync with the target environment or with the source configuration, which often results in painful reconciliation.
I personally am not a huge fan of vendor lock in for multiple reasons:
- I've seen cost saving moves to the cloud end up costing a fortune and trapping companies due to over utilization of cloud specific features.
- I've seen S3 failures nearly take down half the internet.
- I've seen companies get stuck in the cloud because they aren't built cloud agnostic.
I choose to use terraform for my cloud provisioning for these reasons:
- It's cloud agnostic so I can use it no matter where I am.
- It isn't difficult to use and uses a relatively easy to read language.
- It tests infrastructure before running it, and enables me to see and keep changes up to date.
- It runs from the same CLI I do most of my CM work from.
I could define the next points why we have to migrate:
- Decrease build time of our application. (It was the main cause).
- Also
jspm install
takes much more time thannpm install
. - Many config files for SystemJS and JSPM. For Webpack you can use just one main config file, and you can use some separate config files for specific builds using inheritance and merge them.
We mostly use rollup to publish package onto NPM. For most all other use cases, we use the Meteor build tool (probably 99% of the time) for publishing packages. If you're using Node on FHIR you probably won't need to know rollup, unless you are somehow working on helping us publish front end user interface components using FHIR. That being said, we have been migrating away from Atmosphere package manager towards NPM. As we continue to migrate away, we may publish other NPM packages using rollup.
