Containerization and Kubernetes at the moment are important parts for creating scalable cloud-native purposes. However not each utility 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 supply new, fast and streamlined high-availability cluster deployments on Akamai cloud computing providers.
Nomad is each a substitute for or addition to Kubernetes. Nevertheless, Nomad helps extra than containers with different instruments to supply activity drivers, customized “jobs”, or declarative configuration recordsdata with a listing of duties or modifications Nomad ought to full.
Since not each utility can rapidly shift to containerization, Nomad merges cloud-native, container-first growth with help for legacy purposes. This helps dev groups inside a company benefit from utilizing a workload scheduler with out having to fully re-architect their software program.
Nomad joins different Market cluster apps to make deploying and configuring extremely accessible, self-replicating clusters as simple as deploying an app on a single occasion. Market clusters eradicate guide duties and extra scripting usually required to arrange a high-availability surroundings. Clusters incur no extra prices 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 utility may have Kubernetes for giant 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 obligations between Nomad servers and Nomad purchasers. Servers are the brains of the operation when it comes to accepting jobs from customers and delegating duties to purchasers. Nomad purchasers are machines that truly 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 consumer for the cluster, and select whether or not your account SSH keys must be added to all nodes. The cluster utility deploys three Nomad servers, and three Nomad Purchasers.
After your set up is full, you’ll be able to handle your utility’s jobs by way of the Nomad API or use their UI.
Notice: By default, Nomad connects to different cluster members by way of the primary IP detected, so Nomad cluster deployments are restricted to at least one per area. There aren’t 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 may auto-join your current cluster by way of the consul_nomad_autojoin_token generated by your cluster. Study extra.
For workloads that require multi-region replication or personalized configuration, contact our cloud options engineers.
For smaller non-production workloads, Nomad can be accessible as a single occasion deployment.
HashiCorp & Akamai Cloud Computing Providers
Since including Nomad and Vault single occasion deployment apps to our Market final 12 months, we’ve been collaborating with HashiCorp to make IaC-first and cloud-native deployments simple to handle with Akamai.
