HashiCorp Packer vs. TeamCity

We use packer to generate new machine images for multiple platforms on every change to our Configuration Management tools like Chef/Puppet/Ansible It's act single tool for Image building for Multi-provider like AWS/Azure/GCP Helps to achieve Dev/Prod Parity Packer itself doesn't have a state like Terraform. You can't do packer output AMI ID. If you have a scenario where you want to maintain the state for images it would be tough to manage via Packer.

TeamCity is well suited for an organization using continuous integration, meaning you release code to production often, and an agile project management system. There are free versions available for small teams and enterprise versions available for large teams with many different builds. TeamCity is probably overkill for basic e-commerce or blog website builds that do not require much development after the initial launch

• Multi-provider portability
• Greater testability
• Super fast infrastructure deployment

• Fully customizable build process. Each step of the build process can be parameterized and customized to address specific needs of particular applications. This allowed us to easily convert from a custom VM-based environment to our current Docker-based environment.
• Manages large numbers of build agents seamlessly. This allows us to run multiple builds on many different applications in a most efficient manner.
• Build steps can be managed in an arbitrary manner, allowing some parts of the process to proceed in parallel while restricting others to depend on completion of all relevant steps.

• It is not plug and play thing
• Need more specific configurations for smaller projects as well
• Online help is less available
• Basic implementation is easy but I think feature add on can be complex as it involve some language knowledge as well.

We are happy with the use of Packer in our organization. Apart from manageability, I don't find any other drawback with Packer.

It's best for building Image with many features and benefits.

TeamCity runs really well, even when sharing a small instance with other applications. The user interface adequately conveys important information without being overly bloated, and it is snappy. There isn't any significant overhead to build agents or unit test runners that we have measured.

I only once required support and it was very smooth.

I haven't found any issue in Implementation that itself describes how well this tool is built.

There are lot of tools in market which does the job for Image creation but all of them are not complete Machine/Image as a code. All other alternatives can create Image partially. Main reason for selecting Packer are Packer is lightweight, portable, and command-line driven Packer helps keep development, staging, and production as similar as possible. Packer automates the creation of any type of machine image Multi-provider portability is the feature to die for

Jenkins relies on being open source as the primary driver for its success. This low cost is a huge factor for many companies, both small and large. The professional, free tier of TeamCity offers a huge amount of growth before ever needing to pay anything. I personally also find the user experience of TeamCity to be much better, both from a look and feel, as well as from an out-of-the-box feature set perspective. The big selling feature of ADO is its native integration with Azure. TeamCity integrates very well with out-of-the-box .NET support and greatly simplifies our use of another diverse tooling outside of the Microsoft ecosystem.

• Super fast infrastructure deployment
• Quick turnaround of infrastructure in multiple cloud using single tool.
• Increase productivity by reducing time in infrastructure building.

• TeamCity was a key contributor to our organization's adoption of Agile.
• TeamCity made it possible to KILL "It works on my laptop" conversations with Developers. If it does not compile in TeamCity - the project is not deployable. TeamCity's easy to use interface made it possible to quickly adopt a "Deploy Only from TeamCity" policy, further ensuring TeamCity Builds were the gold-standard for well-configured source code.
