We specialize on Amazon Web Services (AWS), which says a lot. There are hundreds of services offered by AWS, which is why we have so much Terraform. Staying on top of it is difficult enoughhttps://aws.amazon.com/new/; new services and features are released daily.
Companies that specialize in multiple platforms (e.g. AWS, Azure, GCP, et al) are spreading themselves thin. In order to maintain a repeatable, cohesive solution, specialization is a requirement. That's why as a DevOps Accelerator, we've deliberately decided to only specialize in Amazon, which has allowed us to go deep and develop a mastery of provisioning AWS services with Terraform.
