"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. The key features of Terraform are: Infrastructure as Code: Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and treated as you would any other code. Additionally, infrastructure can be shared and re-used. Execution Plans: Terraform has a "planning" step where it generates an execution plan. The execution plan shows what Terraform will do when you call apply. This lets you avoid any surprises when Terraform manipulates infrastructure. Resource Graph: Terraform builds a graph of all your resources, and parallelizes the creation and modification of any non-dependent resources. Because of this, Terraform builds infrastructure as efficiently as possible, and operators get insight into dependencies in their infrastructure. Change Automation: Complex changesets can be applied to your infrastructure with minimal human interaction. With the previously mentioned execution plan and resource graph, you know exactly what Terraform will change and in what order, avoiding many possible human errors."

"In 2010 we led the seed round for Docker (formerly known as dotCloud) for one simple reason: devops means that the way applications are packaged, deployed, and run is fundamentally changing (though Docker's business model has evolved since its early days as a PaaS vendor, the fundamental premise is the same).  Rather than requiring custom configurations and painstaking management, Docker "containerizes" applications components such that every container is lightweight and behaves consistently.  Applications and their underlying components can be programmatically deployed, managed and moved on ever-changing cloud infrastructure without a hint of operating system or hardware configuration.  In a pre-Docker world, companies with tremendous and evolving application demands looked to virtualization as a way of abstracting their infrastructure, but paid a tax in dollars and performance for doing so. In the future we think of Docker will take the mantle as the VMware of the devops world, with containers as the ultimate devops platform."

"Clocker features: Automatically create and manage multiple Docker hosts in cloud infrastructure Intelligent container placement, providing: resilience fault tolerance easy scaling maximum resource utilisation of hosts maximum application performance Use of any public or private cloud as the underlying infrastructure for Docker Hosts Deployment of existing Brooklyn/CAMP blueprints to Docker locations, without modification."

"CFEngine is an IT infrastructure automation framework that helps engineers, system administrators and other stakeholders in an IT organization manage and understand IT infrastructure throughout its lifecycle. CFEngine takes systems from Build to Deploy, Manage and Audit."

"Consul has multiple components, but as a whole, it is a tool for discovering and configuring services in your infrastructure. It provides several key features: Service Discovery: Clients of Consul can provide a service, such as api or mysql, and other clients can use Consul to discover providers of a given service. Using either DNS or HTTP, applications can easily find the services they depend upon. Health Checking: Consul clients can provide any number of health checks, either associated with a given service ("is the webserver returning 200 OK"), or with the local node ("is memory utilization below 90%"). This information can be used by an operator to monitor cluster health, and it is used by the service discovery components to route traffic away from unhealthy hosts. Key/Value Store: Applications can make use of Consul's hierarchical key/value store for any number of purposes including: dynamic configuration, feature flagging, coordination, leader election, etc. The simple HTTP API makes it easy to use. Multi Datacenter: Consul supports multiple datacenters out of the box. This means users of Consul do not have to worry about building additional layers of abstraction to grow to multiple regions. Consul is designed to be friendly to both the DevOps community and application developers, making it perfect for modern, elastic infrastructures."

"CoreOS is a Linux distribution that has been rearchitected to provide features needed to run modern clustered infrastructure stacks. The strategies and architectures that influence CoreOS allow companies like Google, Facebook and Twitter to run their services at scale with high resilience. We've implemented them correctly so you don't have to endure the slow, learn-as-you-go infrastructure building process. CoreOS can run on your existing hardware or on most cloud providers. Clustering works across platforms, making it easy to migrate parts of your gear over to CoreOS, or to switch cloud providers while running CoreOS."

"Contentful provides a content infrastructure that enables teams to power content in any digital product."

"New Relic open sourced Centurion, a deployment tool for Docker used internally to run their production infrastructure. Centurion takes containers from a Docker registry and runs them on a fleet of hosts with the correct environment variables, host volume mappings, and port mappings, supporting rolling deployments out of the box."

"Everything at Google, from Search to Gmail, is packaged and run in a Linux container," explained Eric Brewer, vice president of infrastructure at the Internet search giant, in announcing the open sourcing of Kubernetes. "Each week we launch more than 2 billion container instances across our global data centers, and the power of containers has enabled both more reliable services and higher, more-efficient scalability."

"Amazon EC2 Container Service (ECS) is a highly scalable, high performance container management service that supports Docker containers and allows you to easily run applications on a managed cluster of Amazon EC2 instances. Amazon ECS eliminates the need for you to install, operate, and scale your own cluster management infrastructure. With simple API calls, you can launch and stop container-enabled applications, query the complete state of your cluster, and access many familiar features like security groups, Elastic Load Balancing, EBS volumes, and IAM roles. You can use Amazon ECS to schedule the placement of containers across your cluster based on your resource needs and availability requirements. You can also integrate your own scheduler or third-party schedulers to meet business or application specific requirements."

"Today we are very excited to introduce our Docker-based infrastructure stack (codename: Ewok). This release enables you to use Docker containers in your build and deploy pipelines as opposed to our classic boxes."
