Frameworks and tools
Vamp compared to CI/CD tools
Spinnaker, Jenkins, Wercker, Travis, Bamboo
Vamp closes the loop between the development and operations elements of a CI/CD pipeline by enabling the controlled introduction of a deployable into production (canary-test and canary-release) and feeding back runtime technical and business metrics to power automated optimisation workflows (such as autoscalers). Vamp integrates with CI/CD tools like Travis, Jenkins or Wercker to canary-release and scale the built deployables they provide. The initial deployment setup is defined in a YAML blueprint (e.g. deployable details, required resources, routing filters) and is typically provided by the CI tool as a template to the Vamp API. Vamp will then run, canary-release, monitor and scale the deployment based on the filters and conditions specified in the blueprint.
Vamp compared to feature toggle frameworks
LaunchDarkly, Togglz, Petri
Feature toggle frameworks use code level feature toggles to conditionally test new functionality in an application or service. Tools such as LaunchDarkly and Togglz work with these toggles to enable, for example, A/B testing and canary functionality. While there are many cases for using feature toggles, there are also times when feature toggling isn’t the smartest choice. Vamp allows controlled testing of new features without the need to adjust your code. To achieve this, Vamp controls traffic routing towards and between your applications and services based on blueprint descriptions of individual (micro)services and their dependencies. This makes sense on an application code level, offering increased security and reduced technical debt compared to maintaining toggles in your code, and provides a mature alternative for cases when feature toggles are not the appropriate choice.
Vamp compared to configuration management and provisioning tools
Puppet, Ansible, Chef, Terraform
The responsbilities of configuration management and infrastructure provisioning tools are often stretched to cover container deployment features. These tools were not intended for handling container deployments or for the dynamic management and routing traffic over these containers. Vamp has been designed and developed from the ground up specifically to fit these use cases.
Vamp compared to custom built solutions
Building and maintaining a scalable and robust enterprise-grade system for canary-testing and releasing is not trivial. Vamp delivers programmable routing and automatic load balancing, deployment orchestration and workflows, as well as a powerful event system, REST API, graphical UI, integration testing tools and a CLI.
Vamp compared to A/B and MVT testing tools
Optimizely, VisualWebsiteOptimizer, Google Analytics, Planout
Vamp enables canary testing versions of applications, effectively providing A/B and MVT testing of applications and services by deploying two or more versions of an application or service and dividing incoming traffic between the running versions. Vamp doesn’t have a built-in analytics engine though, so the analysing of the relevant metrics needs to be done with a specific Vamp workflow or an external analytics engine. Results can be fed back to Vamp to automatically update routing rules and deployments to push a winning version to a full production release. Because of the flexible programmable routing and use of environment variables, Vamp can be used to canary test almost everything, from content and business logic to configuration settings and architectural changes.
Vamp compared to DevOps tools
Deis, Flynn, Dokku
Vamp has no ambition to provide a Heroku-like environment for containers. Vamp integrates programmable routing and load balancing, container deployments and orchestration to enable canary testing and canary releasing features. Vamp also adds metrics-driven workflows for auto-scaling and other optimisations. Vamp sees business as a first class citizen in DevOps teams, providing a graphical UI and tools for non-technical roles.
