Dtk Glossary

Dtk Server - The brains behind the operation, its an Application that powers workflow/orchestration tasks, and allows users to coordinate and work together across diciplines

Dtk Client - Our CLI tool and programmatic interface for Dtk development and interacting with your Dtk managed Services.

Dtk Network - Site for the Dtk community and public Service Catalog to publish and share modules with other developers.

Dtk Agent - Process which runs on every Dtk managed node that enables communication with Dtk Server and carries out any Application or IT task the Dtk Server directs it to.

Target - You can think of a Target as managed context that all Services and Applications are deployed into. An example would be an AWS Virtual Private Cloud (VPC), or a VSphere managed cluster.

Components - Building are your reusable building blocks for building up complex Services and Applications. They are used to install and/or configure applications, packages, monitoring, etc. Examples of Componets would be Mysql, Nginx, Hadoop, your custom application, AWS VPC, etc.

Action - Actions are the methods/functions available against an instance of a deployed Component. Actions could be things like create/install, delete, upgrade, discover, etc.

Assembly - If Components are building blocks, Assemblies are topology definitions and sets of Components that are linked together to form comprehensive Services. An example would be “three node application with a database, running in a VPC”

Workflow - A Worfklow defines a plan of execution tasks and Actions to be carried out against one or more Dtk managed Service Instances. These tasks can be run against Components that are managed on physical/virtual nodes, or remotely againt external REST services (such as AWS resources). By default the Dtk will auto-generate the default Workflows for you based on the Design/Toplogy of your Assembly. You also have the ability to edit and create your how custom Workflows.

Node - Nodes contain components and can represent a physical, virtual, or container server

Module - Modules handle the depedency management and packaging aspects of a Dtk solution. They consist of reusable, logically grouped Components, Assemblies, and Targets. An example of a module would be “aws_networking” which would contain Components for VPC, Subnet, Internet Gateway, etc.

Service/Service Instance - An Application or Service that has been staged and deployed to a Target. You can think of a Service Instance like an instantiated object, while an Assembly is a class definition
