Containerization and Kubernetes at the moment are important parts for creating scalable cloud-native purposes. However not each software workload wants containers, or requires the sources of Kuberentes. Nomad by HashiCorp is a light-weight workload scheduler that gives a number of the advantages of Kubernetes, however works with extra than simply containers. We collaborated with groups at HashiCorp to offer new, fast and streamlined high-availability cluster deployments on Akamai cloud computing companies.

Nomad is each a substitute for or addition to Kubernetes. Nonetheless, Nomad helps extra than containers with different instruments to offer activity drivers, customized “jobs”, or declarative configuration recordsdata with an inventory of duties or modifications Nomad ought to full.

Since not each software can shortly shift to containerization, Nomad merges cloud-native, container-first improvement with help for legacy purposes. This helps dev groups inside a corporation reap the benefits of utilizing a workload scheduler with out having to utterly re-architect their software program.

Nomad joins different Market cluster apps to make deploying and configuring extremely obtainable, self-replicating clusters as simple as deploying an app on a single occasion. Market clusters eradicate handbook duties and extra scripting sometimes required to arrange a high-availability surroundings. Clusters incur no extra costs and solely invoice for the sources used.

How It Works

Nomad permits you to deploy and handle each containerized purposes and non-containerized legacy purposes utilizing a single unified workflow. For instance, your software may have Kubernetes for big scale container orchestration, however Nomad can deal with standalone purposes, together with uncooked binaries, Java Jar recordsdata, and QEMU/KVM digital machines.

On the backend, Nomad divides duties between Nomad servers and Nomad purchasers. Servers are the brains of the operation by way of accepting jobs from customers and delegating duties to purchasers. Nomad purchasers are machines that really run the duties designated to them. Nomad makes use of bin packaging for environment friendly job scheduling and useful resource optimization, and leverages Consul as a service discovery mesh to run between three and 5 servers.

To deploy a cluster utilizing our Market, merely add your Linode API token, the restricted sudo person for the cluster, and select whether or not your account SSH keys ought to be added to all nodes. The cluster software deploys three Nomad servers, and three Nomad Purchasers.

After your set up is full, you’ll be able to handle your software’s jobs through the Nomad API or use their UI.

Observe: By default, Nomad connects to different cluster members through the primary IP detected, so Nomad cluster deployments are restricted to at least one per area. There are not any limits for scaling horizontally through the use of the Nomad Purchasers Cluster app so as to add 3, 5, or 7 extra compute occasion purchasers that can auto-join your current cluster through the consul_nomad_autojoin_token generated by your cluster. Be taught extra.

For workloads that require multi-region replication or custom-made configuration, contact our cloud options engineers.

For smaller non-production workloads, Nomad can also be obtainable as a single occasion deployment.

HashiCorp & Akamai Cloud Computing Companies

Since including Nomad and Vault single occasion deployment apps to our Market final yr, we’ve been collaborating with HashiCorp to make IaC-first and cloud-native deployments simple to handle with Akamai. For extra HashiCorp instruments on Akamai, try our Terraform Supplier and Terraform guides.

See You at HashiConf!

Attending HashiConf in San Francisco this month? Cease by the Akamai gaming lounge to talk with our group, get swag, and study extra in regards to the Nomad Cluster.
