HashiCorp Announcements at HashiConf 2017
Today at HashiConf 2017 in Austin, Texas, we announced major updates and new features across our entire suite of open source and enterprise products, including HashiCorp Terraform, HashiCorp Vault, HashiCorp Consul, and HashiCorp Nomad. In addition to these product updates, we announced the release of Sentinel, our new policy as code framework that integrates across the Enterprise product suite, and the Terraform Module Registry, which provides example infrastructure templates to make provisioning across cloud environments easier, and so much more.

Continuous Deployment with Nomad and Terraform
This post explores how to use the Nomad Terraform provider to control the lifecycle of a Nomad service.
Both HashiCorp Nomad and Terraform allow you to declaratively define infrastructure as code, but they serve different functions in the organization. Nomad schedules and monitors applications, making sure the application stays running and automatically reconciles any failure. Nomad supports rolling deploys to deliver safer convergence. Nomad also integrates with Consul for service discovery and Vault for secrets management. Terraform, on the other hand, is a lifecycle management and provisioning tool. It creates, updates, and destroys the underlying infrastructure which Nomad will use to run applications. But Terraform is much more than a infrastructure tool - Terraform can also manage the process of submitting, updating, and deleting Nomad applications, which will allows modeling your entire infrastructure as code.
The Nomad Terraform provider is perfect for continuous delivery for your applications, and in this post we will look at how these tools work seamlessly together to enable this workflow.

HashiCorp Nomad 0.6
We are pleased to announce the release of HashiCorp Nomad 0.6. Nomad is a distributed, scalable, and highly available cluster manager and scheduler designed for both microservice and batch workloads.
Nomad 0.6 includes a number of new features focused on improving job management and configuration as well as many improvements and bug fixes. Highlights include:Job deployments Job history and ability to revert to older versions Dynamic environment variables Automatic advertisement of container IP addresses with HashiCorp Consul
We are also pleased to announce that the Nomad ecosystem now includes a version of Apache Spark that natively integrates Nomad as a Spark cluster manager and scheduler. See our Running Apache Spark on Nomad blog post for additional details.

Running Apache Spark on HashiCorp Nomad
Apache Spark is a popular data processing engine/framework that has been architected to use third-party schedulers. The schedulers that are available, however, involve a level of complexity that can be undesirable for many potential Spark users. To help fill this gap, we are pleased to announce that the HashiCorp Nomad ecosystem now includes a version of Apache Spark that natively integrates Nomad as a Spark cluster manager and scheduler.

Auto-bootstrapping a Nomad Cluster
In a previous post, we explored how HashiCorp Consul discovers other agents using cloud metadata to bootstrap a cluster. This post looks at HashiCorp Nomad's auto-joining functionality and how we can use Terraform to create an autoscaled cluster.

Replacing Queues with Nomad Dispatch
Nomad v0.5.3 introduced parameterized jobs which act as job scaffolds that can be dispatched on demand with configurable arguments. These jobs behave similar to functions, encapsulating the logic and allowing the caller to name the job and provide appropriate arguments. Nomad Dispatch treats those "function calls" like a future or promise, making it easy to build scalable processing pipelines for operations like video transcoding, image resizing, sending emails, or doing a billing rollup.
This blog post explores using the new Nomad Dispatch feature to build a video transcoding service using the popular open source tool ffmpeg. Traditional approaches to this problem often involve many different components for work queuing, scheduling, capacity planning, and failure handling. Due to its design, Nomad automatically handles these concerns, allowing for focus on a minimal job definition and the business logic of the video transcoding service.

Today we announce Nomad, a cluster manager and scheduler designed for microservices and batch workloads. Nomad is distributed, highly available, and scales to thousands of nodes spanning multiple datacenters and regions.
Nomad provides a common workflow to deploy applications across an infrastructure. Developers use a declarative job specification to define how an application should be deployed and the resources it requires (CPU, memory, disk). Nomad accepts these jobs and finds available resources to run them. The scheduling algorithm ensures all constraints are satisfied, and packs as many applications on a host as possible to optimize resource utilization. Additionally, Nomad supports virtualized, containerized, or standalone applications running on all major operating systems giving it the flexibility to support a broad range of workloads.
Nomad is now being deployed in production environments and we are proud to share it publicly. We are excited about the future of the project, and are just beginning to build on the foundation that it provides.
