Terraform

Avantages

Terraform makes it convenient to manage a multi-cloud environment. It allowed me to create and maintains standard templates across environments for databases.

Inconvénients

Debugging and troubleshooting issues related to config and deployment can get difficult due to limited error messages and also the complexity of software

Avantages

It's easily the best Infrastructure as Code tool available in the market.

Inconvénients

Some providers are still not mature enough.

Pourquoi passer à Terraform

Avantages

1. Terraform state file which keeps the record of all the provision resources done by using Terraform script.
2. Reduces the repetitive task of developers: If there are resources which are created in Development environment and we need the same resources in Production environment too. Then instead of developers provisioning resources manually, we can easily reuse the terraform scripts that were used in Development environment to provision resources .
3. Terraform manages infrastructure on multiple cloud platforms like Azure, AWS, etc.

Inconvénients

1. Less Examples in documentation.
2. Less support.
3. Since Terraform is new IAAS, there are many changes or upgrades going on.

Avantages

The ease of use and the speed at which bug fixes and related enhancements can be submitted via GitHub and be approved and so you end up running your amendments without needing to work around them.

Inconvénients

One aspect is that there is a library that doesn't include all aspects of Terraform and so dependent applications are not fully capable of exposing all the aspects.

Pourquoi passer à Terraform

Avantages

What i like most is terraform is cloud agnostic and i like the reusability of terraform modules for faster infrastructure provisioning.

Inconvénients

what i like least is that when we write thousands of lines of code then managing the state becomes difficult.

Avantages

1. It is very extensible and works with multiple cloud platforms, popular hosting platforms like DigitalOcean, GoDaddy etc. Terraform uses providers for interacting with vendor specific APIs for provisioning infrastructure.
2. It uses HCL (Hashicorp language) which is quite powerful compared to plain YAML or JSON. Many other IAC tools use plain YAML or JSON - which can be limiting. With HCL, you get for loops, conditionals, and even the ability to get data from different data sources and even shell scripts
3. It is easy to run Terraform code from a Jenkins or any other build pipeline.

Inconvénients

The state file management could be better. Although wrapper solutions like Terragrunt exist, it would be great if Tearrform's native capabilities with state management could be even better. Other nitpick is: secrets end up in plain text in state file. Hashicorp suggest using their product vault to avoid this issue. But, not everyone uses or wants to use Vault.

Pourquoi passer à Terraform

Avantages

Deploy Infrastructure rapidly and dependably. Repeatability because of utilization of modules. the suppliers work really hard keeping awake to date on the most recent changes from the Cloud suppliers Features Updates. This makes exploiting the new elements dispatched not an issue. Terraform is totally and absolutely better than utilizing CloudFormation straightforwardly.

Inconvénients

The actual language is somewhat surprising and this makes it difficult for new clients to get onboarded into the codebase. While it's improving with later deliveries, essential ideas like "map a variety of choices into a bunch of designs" or "apply this rationale in the event that a variable is indicated" are conceivable however superfluously unwieldy. A rollback component would be a welcome expansion to Terraform. At the time I'm composing this, when Terraform experiences a mistake, it stops on the progression where the blunder is experienced and any assets recently made are left set up. While this is wanted as a rule, and choice for moving back those assets would give usefulness like other IaC devices.

Pourquoi passer à Terraform

Avantages

Foremost, terraform is cloud agnostic so you just select your cloud provider and get started with provisioning cloud environment with terraform. The language is easy to understand & allows you to create reusable templates & modules. When making changes it shows all the changes in state that are going to be made during terraform plan, which is very helpful before we actually start applying them.
You can also use remote executors to run some external logic of code through bash before provisioning.

Inconvénients

Looping strategies like for_each are rather complex to understand when you are new to terraform.
It does not have a rollback feature & if something fails all the changes before that failed change would still be applied.
Some conditional logics are unnecessarily cumbersome.
Also overally analytics for users running plan & apply is missing, it's better for management purpose & debugging the plan which might have caused an infra issue.

Avantages

Terraform was a game changer for me as a DevOps Engineer. I love how your infrastructure is stored as code in git and you can see the history of any changes made. I also like that you can scale your infrastructure a lot easier using terraform than through 'Click Ops' simply by using modules and creating new resources in code.

Inconvénients

One of my main problems with Terraform is when I'm trying to delete things and I end up with dependencies blocking the deletion. Sometimes I need to manipulate state and am left with orphaned resources. When things don't work, it's tricky to troubleshoot.

Avantages

Makes most things easier. Learning HCL and transforming to Infrastructure-As-Code is is a paradigm shift and not an easy one but a very interesting one which will help us become more agile and deliver faster and more reliable.

Inconvénients

A steep learning curve for many and it a very different way of thinking doing IAC but Terraform makes it easy to deliver the same product consistently.

Avantages

Lo que más destacaría de Terraform es su capacidad de automatización. El lenguaje HCL es muy intuitivo y permite poder crear scripts de forma muy sencilla para poder aprovisionar recursos y hacer despliegues automáticos.

Inconvénients

Un aspecto que mejoraría de Terraform es el manejo de dependencias entre distintos recursos cuando se trabaja con infraestructuras que son algo complejas.

Avantages

Terraform supports multiple cloud providers, including AWS, Azure, and Google Cloud Platform, offering flexibility and reducing vendor lock-in.

Inconvénients

While Terraform has some rollback mechanisms, they might not be as comprehensive or straightforward compared to specialized rollback solutions.

Avantages

With HashiCorp Terraform, multiple teams in our organization can make changes to our AWS cloud infrastructure concurrently, synchronizing via Git. All resources are visible in the Terraform code as modules, and the code is highly reusable: our Infrastructure team defines modules that the application teams can use and customize via configuration parameters. The terraform plan and apply steps ensure repeatable configuration of our cloud resources even if they need to be recreated from scratch.

Inconvénients

For new users it’s quite hard to learn: the syntax is not very intuitive (even though it is human-readable) and many modules require positional arguments.

Avantages

There are a lot of providers available for free. A provider allow you to configure services for a particular cloud provider or service. In the last versions they have improved a lot the process to calculate the differences between the status on the code and the status on the target infrastructure.

Inconvénients

Terraform don't offer a ready to use and free system to manage different environments. You have to use branched or external tools like Terragrunt.

Avantages

Terraform is great at building and managing lots of different tech setups with a lot of helpful add-ons and ability to repeat tasks easily.

Inconvénients

Despite being powerful, Terraform sometimes makes simple tasks hard and can be difficult to learn for new users.

Avantages

The best thing about Terraform is it's a free, open-source, and very easy-to-learn tool for provisioning and managing infrastructure as code. Some features like version control, reusability of modules, and multi-cloud features are very well integrated.

Inconvénients

State management can be a bit complex sometimes. While starting with Terraform, users need to learn a new language ie HCL.

Avantages

Terraform supports a lot of 3rd party tools. And there are modules from many Cloud providers. The thing I like is that many indie developers write useful modules for Terraform which really helps in automating important tasks. The sky is the limit in automation when you are using Terraform. For example, we used to use Venafi software for SSL renewal which was a manual process and the certificates were placed in buckets. But we were able to automate the process using Venafi provider and local-exec.

Inconvénients

User and Access management is a miss. We had to use workspace, and shell scripts to check the correct access of different resources.Also it can get complicated if you don't have a structure for your code. So using templates from start is a good way.

Avantages

This software is the market leader in IaaS infrastructure deployments, as you can use multicloud deployments, relatively low learning curve, and team will be able to eventually deploy all services and infrastructure using Terraform which is many organization's, is best practice.

Inconvénients

There is not much I don't like form this software, is a pleasure to use and different way of approaching IaaS to environements.

Avantages

We work with multiple clients, one might have Google Cloud, the other Azure, another Oracle Cloud and some VMWare. Terraform makes it easy to deploy in the cloud or on prem. 80% of the time I am using modules that have been created by others which speeds up our deployments.

Inconvénients

Learning curve for IT teams that are used to manual deployments.

Avantages

Terraform is best cloud management tool which provide infrastructure as code service . we are using terraform for AWS infrastructure management as code. We can use multiple workspace for our project and destroy workspace after use. Terraform uses HashiCrop language for creating human readable infrastructure code we can reuse same code , maintain version and source control. Terraform registry provide ready to use quick feature for easy development .

Inconvénients

The only cons I found that sometime it takes times.

Avantages

Open source versions allow you to get started straight away, with cloud and enterprise platforms that easily let you take it to the next level. These tools are a must have for any cloud computing shop. The ability to define the computing environment in code in a platform neutral way, provides the business with the flexibility necessary in 2020.

Inconvénients

Some quirky things in the HCL language, but major improvements were made in HCL2 (speaking specifically of TerraForm).

It does take some time to get going with some of the concepts, but the documentation has drastically improved.

Avantages

- State management
- Open source
- Not agent based

Inconvénients

- Becomes bit tricky when it comes to logic handling.

Avantages

● HashiCorp Terraform Integrates with over 125 providers including major cloud providers such as Google Cloud Platform, Azure, AWS etc, version control repository hosting providers such github, gitlab etc and many more. This makes provisioning, management, updating, maintenance and destruction of resources easier.
● HashiCorp products have proper and efficient documentation that makes a new user get started easily.
● HashiCorp products have a large and active community support since their products are open source.
● Hashicorp products have an easy to use interface.

Inconvénients

● Management of state files that holds information of the infrastructure and changes may be an issue sometimes especially if a number of users are allowed to carry out new changes to the infrastructure.

Avantages

Infrastructure as code implementation, cloud agnostic technology, configuration management, single source of truth for infrastructure setup

Inconvénients

Constant upgrades needed to get new features, pre-defined directory structure, lots of missing features/bugs in the Azure provider

Avantages

Terraform was the first big player in the infrastructure as code game and became a de-facto standard. Byupporting different providers, it allows integrating a huge variety of components and helps to avoid Cloud vendor lock-in.

Inconvénients

Breaking changes across versions make supporting it a bit more complex than it could be.
