Today at HashiConf 2018 in San Francisco, we are announcing major updates across our entire suite of open source and enterprise products. Our mission is to allow users to run applications on any infrastructure, cloud or on-premises, using a modern infrastructure as code approach. This blog is a summary of the announcements being made at the event.

It seems that containers are everywhere. They should be. They make it easier to deploy applications into environments for development, testing and in production. However, what about when containers just don’t work? To take full advantage of the container orchestration platforms currently available there has to be considerable changes made to the applications and the deployment processes. For green field applications this is not a problem as they are usually built with containers in mind. What do you do if you want to have the advantages of a container-like scheduler but for your legacy applications? Enter HashiCorp Nomad.

Apache Heron is a stream processing engine (SPE) open sourced by Twitter in 2016 and now currently in incubation under the auspices of the Apache Software Foundation. At Twitter, Heron was built to provide multi-tenancy, efficient resource usage, support for a variety of programming languages and APIs, operational simplicity at massive scale, and high productivity for developers building both real-time and batch services. Today, Heron serves the lion’s share of Twitter’s massive real-time processing needs, is used by numerous large enterprises, and has a thriving open source community.
As a core contributor to Heron, I’m excited to announce that Nomad is being added as a fully supported scheduler for Heron.

At HashiCorp, we’ve always said that all of our projects should work well separately, but better together. This is certainly true for HashiCorp Terraform and HashiCorp Nomad. Terraform provisions the infrastructure and Nomad schedules and deploys applications. When deploying Nomad, you may do this however you like, and the Nomad team strives to make that easy to do, but if you opt to use Terraform to manage the servers that Nomad runs on, we believe that should offer a first-class experience.

A lot of HashiCorp users and employees love our whole suite of products, but like with your grandmother, it’s almost impossible not to have one slight predilection over one of our creations (says the favorite grandchild). In my case, my predilection for HashiCorp Nomad is quite evident, to the point of being a running joke among the European team. I think not a single customer meeting goes by without someone saying "yeah, that’s Nomad, Nico’s favorite product…".

No one wants to manage storage, but high-value applications aren’t going to run without it. In an ideal world, storage would “just be there” without having to think about it --- or provision and manage it, right?
Portworx, a software-defined persistent storage solution for container workloads, provides a highly-available elastic data fabric. Portworx cloud native storage allows jobs to seamlessly run hyper-converged with the storage layer for best performance --- and also provides a rich spectrum of options for data availability.

OpenFaaS (or Functions as a Service) is a framework for building serverless functions but with containers. With OpenFaaS you can package any process or container as a serverless function for either Linux or Windows - just bring your Nomad cluster. The project focuses on ease of use through its UI and CLI which can be used to test and monitor functions in tandem with Prometheus enabling auto-scaling.

Guest post from Pavel Klushin, Solutions Architect at Spotinst.
Utilizing capacity in the cloud can save a lot of money, but taking advantage of those savings requires a lot of work. Spotinst, is a platform for running and managing elastic cloud compute and enables companies to reduce their compute infrastructure costs by 60-80%. HashiCorp Nomad provides easy-to-use and flexible cluster management and container scheduling. Nomad and Spotinst Elastigroup together allow you to efficiently deploy containerized workloads and easily manage clusters at any scale for a fraction of the cost.

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.

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.

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.

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.
Read on to learn more.
