Packer was used to build machine images for AWS, GCP, DigitalOcean, VMware … Also Docker images were build in some cases using Packer.
Vagrant was used in some cases to deploy instances in a VMware cluster for testing purposes. After all the testing was successful, the images were uploaded to be used in AWS, GCP or in other cloud provides, depending on the clients request.
Helm charts were used to manage Kubernetes applications. In some situations Kubernetes was deployed on-premises using Kubespray. For this situations a VMware hyperconverged infrastructure was build before deploying the Kubernetes cluster on-top of it.
The deployments were provisioned using Ansible and also the infrastructure was heterogeneous comprised of different flavors of Linux [ Red Hat, CentOS, Ubuntu ]. Ansible was used for tasks like configuring systems and also configuring the apps that were running on-top of those systems, like in some cases Jboss/Wildfly .
For CI/CD different tools were used. Tools like Jenkins, Bamboo and TeamCity, although Jenkins was the more common one.
Projects related to preparation, planning, coordination and execution of penetration tests. Determining and identifying of possible attack vectors. For this tests, vulnerability scanners like Nessus or Nexpose were used.
