What is Kubernetes?

Kubernetes is a portable, extensible open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available.

What is Terraform?

Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. Terraform can manage existing and popular service providers as well as custom in-house solutions.

Configuration files describe to Terraform the components needed to run a single application or your entire datacenter. Terraform generates an execution plan describing what it will do to reach the desired state, and then executes it to build the described infrastructure. As the configuration changes, Terraform is able to determine what changed and create incremental execution plans which can be applied.

The infrastructure Terraform can manage includes low-level components such as compute instances, storage, and networking, as well as high-level components such as DNS entries, SaaS features, etc.

What is Packer?

In DevOps Online Training at Visualpath Teaching You a complete Paker tool.Packer is an open source tool for creating identical machine images for multiple platforms from a single source configuration. Packer is lightweight, runs on every major operating system, and is highly performant, creating machine images for multiple platforms in parallel. Packer does not replace configuration management like Chef or Puppet. In fact, when building images, Packer is able to use tools like Chef or Puppet to install software onto the image.

A machine image is a single static unit that contains a pre-configured operating system and installed software which is used to quickly create new running machines. Machine image formats change for each platform. Some examples include AMIs for EC2, VMDK/VMX files for VMware, OVF exports for VirtualBox, etc.

What is DevSecOps? Developing more secure applications

DevSecOps is about introducing security earlier in the life cycle of application development, thus minimizing vulnerabilities and bringing security closer to IT and business objectives.

Why DevSecOps is important

IT infrastructure has undergone huge changes in recent years. The shift to dynamic provisioning, shared resources and cloud computing have driven benefits around IT speed, agility and cost, and all of this has helped to improve application development.

The ability to deploy applications in the cloud has improved both scale and speed, the move to agile and DevOps methodologies (and with that, continuous delivery) making “big bang” application launches a thing of the past. In particular, DevOps -- the principle of integrating development and IT operations under a “single automated umbrella” -- has helped with everything from more frequent feature releases to increased application stability.

Benefits of DevSecOps

The benefits are simple: More automation from the start reduces the chance of misadministration and mistakes, which often leads to downtime or attacks. This automation also reduces the need for security architects to manually configure security consoles.

DevOps vs. DevSecOps: The integration

Integrating security into DevOps Online Training to deliver DevSecOps requires new mindsets, processes, and tools. Security and risk management leaders need to adhere to the collaborative, agile nature of DevOps to be seamless and transparent in the development process, making security as silent and seamless as possible. However, this is difficult for two different disciplines.

“The issue here is that DevOps is about services and being more aligned to agile approaches,” says Cuthbert. “For example, treating your infrastructure as code, the security element is rarely discussed. At the moment, we still seem to have two camps: one that subscribes to the DevOps process and others that choose DevSecOps. I think we need to align these camps to just ensure security is included in the decisions and lifecycle of all aspects of the process.”
