|

}
|
||||
```
|
||||
|
||||
## `server_join` Parameters
|
||||
|
||||
- `retry_join` `(array<string>: [])` - Specifies a list of server addresses to
|
||||
join. This is similar to [`start_join`](#start_join), but will continue to
|
||||
be attempted even if the initial join attempt fails, up to
|
||||
[retry_max](#retry_max). Further, `retry_join` is available to
|
||||
both Nomad servers and clients, while `start_join` is only defined for Nomad
|
||||
servers. This is useful for cases where we know the address will become
|
||||
available eventually. Use `retry_join` with an array as a replacement for
|
||||
`start_join`, **do not use both options**.
|
||||
|
||||
Address format includes both using IP addresses as well as an interface to the
|
||||
[go-discover](https://github.com/hashicorp/go-discover) library for doing
|
||||
automated cluster joining using cloud metadata. See [Cloud
|
||||
Auto-join][cloud_auto_join] for more information.
|
||||
|
||||
```
|
||||
server_join {
|
||||
retry_join = [ "1.1.1.1", "2.2.2.2" ]
|
||||
}
|
||||
```
|
||||
|
||||
Using the `go-discover` interface, this can be defined both in a client or
|
||||
server configuration as well as provided as a command-line argument.
|
||||
|
||||
```
|
||||
server_join {
|
||||
retry_join = [ "provider=aws tag_key=..." ]
|
||||
}
|
||||
```
|
||||
|
||||
See the [server address format](#server-address-format) for more information
|
||||
about expected server address formats.
|
||||
|
||||
- `retry_interval` `(string: "30s")` - Specifies the time to wait between retry
|
||||
join attempts.
|
||||
|
||||
- `retry_max` `(int: 0)` - Specifies the maximum number of join attempts to be
|
||||
made before exiting with a return code of 1. By default, this is set to 0
|
||||
which is interpreted as infinite retries.
|
||||
|
||||
- `start_join` `(array<string>: [])` - Specifies a list of server addresses to
|
||||
join on startup. If Nomad is unable to join with any of the specified
|
||||
addresses, agent startup will fail. See the
|
||||
[server address format](#server-address-format) section for more information
|
||||
on the format of the string. This field is defined only for Nomad servers and
|
||||
will result in a configuration parse error if included in a client
|
||||
configuration.
|
||||
|
||||
## Server Address Format
|
||||
|
||||
This section describes the acceptable syntax and format for describing the
|
||||
location of a Nomad server. There are many ways to reference a Nomad server,
|
||||
including directly by IP address and resolving through DNS.
|
||||
|
||||
### Directly via IP Address
|
||||
|
||||
It is possible to address another Nomad server using its IP address. This is
|
||||
done in the `ip:port` format, such as:
|
||||
|
||||
```
|
||||
1.2.3.4:5678
|
||||
```
|
||||
|
||||
If the port option is omitted, it defaults to the Serf port, which is 4648
|
||||
unless configured otherwise:
|
||||
|
||||
```
|
||||
1.2.3.4 => 1.2.3.4:4648
|
||||
```
|
||||
|
||||
### Via Domains or DNS
|
||||
|
||||
It is possible to address another Nomad server using its DNS address. This is
|
||||
done in the `address:port` format, such as:
|
||||
|
||||
```
|
||||
nomad-01.company.local:5678
|
||||
```
|
||||
|
||||
If the port option is omitted, it defaults to the Serf port, which is 4648
|
||||
unless configured otherwise:
|
||||
|
||||
```
|
||||
nomad-01.company.local => nomad-01.company.local:4648
|
||||
```
|
||||
|
||||
### Via the go-discover interface
|
||||
|
||||
As of Nomad 0.8.4, `retry_join` accepts a unified interface using the
|
||||
[go-discover](https://github.com/hashicorp/go-discover) library for doing
|
||||
automated cluster joining using cloud metadata. See [Cloud
|
||||
Auto-join][cloud_auto_join] for more information.

|

The `server_join` stanza specifies how the Nomad agent will discover and connect
|
||||
to Nomad servers.
|
||||
|
||||
```json
|
||||
{
|
||||
"retry_join": ["provider=my-cloud config=val config2=\"some other val\" ..."]
|
||||
```hcl
|
||||
server_join {
|
||||
retry_join = [ "1.1.1.1", "2.2.2.2" ]
|
||||
retry_max = 3
|
||||
retry_interval = "15s"
|
||||
}
|
||||
```
|
||||
|
||||
The cloud provider-specific configurations are detailed below. This can be
|
||||
combined with static IP or DNS addresses or even multiple configurations
|
||||
for different providers.
|
||||
## `server_join` Parameters
|
||||
|
||||
In order to use discovery behind a proxy, you will need to set
|
||||
`HTTP_PROXY`, `HTTPS_PROXY` and `NO_PROXY` environment variables per
|
||||
[Golang `net/http` library](https://golang.org/pkg/net/http/#ProxyFromEnvironment).
|
||||
- `retry_join` `(array<string>: [])` - Specifies a list of server addresses to
|
||||
join. This is similar to [`start_join`](#start_join), but will continue to
|
||||
be attempted even if the initial join attempt fails, up to
|
||||
[retry_max](#retry_max). Further, `retry_join` is available to
|
||||
both Nomad servers and clients, while `start_join` is only defined for Nomad
|
||||
servers. This is useful for cases where we know the address will become
|
||||
available eventually. Use `retry_join` with an array as a replacement for
|
||||
`start_join`, **do not use both options**.
|
||||
|
||||
The following sections give the options specific to a subset of supported cloud
|
||||
provider. For information on all providers, see further documentation in
|
||||
[go-discover](https://github.com/hashicorp/go-discover).
|
||||
Address format includes both using IP addresses as well as an interface to the
|
||||
[go-discover](https://github.com/hashicorp/go-discover) library for doing
|
||||
automated cluster joining using cloud metadata. See the [Cloud Auto-join](#cloud-auto-join)
|
||||
section below for more information.
|
||||
|
||||
```
|
||||
server_join {
|
||||
retry_join = [ "1.1.1.1", "2.2.2.2" ]
|
||||
}
|
||||
```
|
||||
|
||||
Using the `go-discover` interface, this can be defined both in a client or
|
||||
server configuration as well as provided as a command-line argument.
|
||||
|
||||
```
|
||||
server_join {
|
||||
retry_join = [ "provider=aws tag_key=..." ]
|
||||
}
|
||||
```
|
||||
|
||||
See the [server address format](#server-address-format) for more information
|
||||
about expected server address formats.
|
||||
|
||||
- `retry_interval` `(string: "30s")` - Specifies the time to wait between retry
|
||||
join attempts.
|
||||
|
||||
- `retry_max` `(int: 0)` - Specifies the maximum number of join attempts to be
|
||||
made before exiting with a return code of 1. By default, this is set to 0
|
||||
which is interpreted as infinite retries.
|
||||
|
||||
- `start_join` `(array<string>: [])` - Specifies a list of server addresses to
|
||||
join on startup. If Nomad is unable to join with any of the specified
|
||||
addresses, agent startup will fail. See the
|
||||
[server address format](#server-address-format) section for more information
|
||||
on the format of the string. This field is defined only for Nomad servers and
|
||||
will result in a configuration parse error if included in a client
|
||||
configuration.
|
||||
|
||||
## Server Address Format
|
||||
|
||||
This section describes the acceptable syntax and format for describing the
|
||||
location of a Nomad server. There are many ways to reference a Nomad server,
|
||||
including directly by IP address and resolving through DNS.
|
||||
|
||||
### Directly via IP Address
|
||||
|
||||
It is possible to address another Nomad server using its IP address. This is
|
||||
done in the `ip:port` format, such as:
|
||||
|
||||
```
|
||||
1.2.3.4:5678
|
||||
```
|
||||
|
||||
If the port option is omitted, it defaults to the Serf port, which is 4648
|
||||
unless configured otherwise:
|
||||
|
||||
```
|
||||
1.2.3.4 => 1.2.3.4:4648
|
||||
```
|
||||
|
||||
### Via Domains or DNS
|
||||
|
||||
It is possible to address another Nomad server using its DNS address. This is
|
||||
done in the `address:port` format, such as:
|
||||
|
||||
```
|
||||
nomad-01.company.local:5678
|
||||
```
|
||||
|
||||
If the port option is omitted, it defaults to the Serf port, which is 4648
|
||||
unless configured otherwise:
|
||||
|
||||
```
|
||||
nomad-01.company.local => nomad-01.company.local:4648
|
||||
```
|
||||
|
||||
### Via the go-discover interface
|
||||
|
||||
As of Nomad 0.8.4, `retry_join` accepts a unified interface using the
|
||||
[go-discover](https://github.com/hashicorp/go-discover) library for doing
|
||||
automated cluster joining using cloud metadata. See [Cloud
|
||||
Auto-join][cloud_auto_join] for more information.
|
||||
|
||||
```
|
||||
"provider=aws tag_key=..." => 1.2.3.4:4648
|
||||
```
|
||||
|
||||
## Cloud Auto-join
|
||||
|
||||
The following sections describe the Cloud Auto-join `retry_join` options that are specific
|
||||
to a subset of supported cloud providers. For information on all providers, see further
|
||||
documentation in [go-discover](https://github.com/hashicorp/go-discover).

# Service Discovery
|
||||
|
||||
Nomad schedules workloads of various types across a cluster of generic hosts.
|
||||
Because of this, placement is not known in advance and you will need to use
|
||||
service discovery to connect tasks to other services deployed across your
|
||||
cluster. Nomad integrates with [Consul][] to provide service discovery and
|
||||
monitoring.
|
||||
|
||||
Note that in order to use Consul with Nomad, you will need to configure and
|
||||
install Consul on your nodes alongside Nomad, or schedule it as a system job.
|
||||
Nomad does not currently run Consul for you.
|
||||
|
||||
## Configuration
|
||||
|
||||
To enable Consul integration, please see the
|
||||
[Nomad agent Consul integration](/docs/agent/configuration/consul.html)
|
||||
configuration.
|
||||
|
||||
|
||||
## Service Definition Syntax
|
||||
|
||||
To configure a job to register with service discovery, please see the
|
||||
[`service` job specification documentation][service].
|
||||
|
||||
## Assumptions
|
||||
|
||||
- Consul 0.7.2 or later is needed for `tls_skip_verify` in HTTP checks.
|
||||
|
||||
- Consul 0.6.4 or later is needed for using the Script checks.
|
||||
|
||||
- Consul 0.6.0 or later is needed for using the TCP checks.
|
||||
|
||||
- The service discovery feature in Nomad depends on operators making sure that
|
||||
the Nomad client can reach the Consul agent.
|
||||
|
||||
- Tasks running inside Nomad also need to reach out to the Consul agent if
|
||||
they want to use any of the Consul APIs. Ex: A task running inside a docker
|
||||
container in the bridge mode won't be able to talk to a Consul Agent running
|
||||
on the loopback interface of the host since the container in the bridge mode
|
||||
has its own network interface and doesn't see interfaces on the global
|
||||
network namespace of the host. There are a couple of ways to solve this, one
|
||||
way is to run the container in the host networking mode, or make the Consul
|
||||
agent listen on an interface in the network namespace of the container.

# Cloud Auto-joining
|
||||
|
||||
As of Nomad 0.8.4,
|
||||
[`retry_join`](/docs/configuration/server_join.html#retry_join) accepts a
|
||||
unified interface using the
|
||||
[go-discover](https://github.com/hashicorp/go-discover) library for doing
|
||||
automatic cluster joining using cloud metadata. To use retry-join with a
|
||||
supported cloud provider, specify the configuration on the command line or
|
||||
configuration file as a `key=value key=value ...` string. Values are taken
|
||||
literally and must not be URL encoded. If the values contain spaces, backslashes
|
||||
or double quotes thenthey need to be double quoted and the usual escaping rules
|
||||
apply.
|
||||
|
||||
```json
|
||||
{
|
||||
"retry_join": ["provider=my-cloud config=val config2=\"some other val\" ..."]
|
||||
}
|
||||
```
|
||||
|
||||
The cloud provider-specific configurations are documented [here](/docs/configuration/server_join.html#cloud-auto-join).
|
||||
This can be combined with static IP or DNS addresses or even multiple configurations
|
||||
for different providers. In order to use discovery behind a proxy, you will need to set
|
||||
`HTTP_PROXY`, `HTTPS_PROXY` and `NO_PROXY` environment variables per
|
||||
[Golang `net/http` library](https://golang.org/pkg/net/http/#ProxyFromEnvironment).

Learn how to integrate Nomad with Consul and add service discovery to jobs

|

|

# Consul Integration
|
||||
|
||||
[Consul][] is a tool for discovering and configuring services in your
|
||||
infrastructure. Consul's key features include service discover, health checking,
|
||||
a KV store, and robust support for multi-datacenter deployments. Nomad's integration
|
||||
with Consul enables automatic clustering, built-in service registration, and
|
||||
dynamic rendering of configuration files and environment variables. The sections
|
||||
below describe the integration in more detail.
|
||||
|
||||
## Configuration
|
||||
|
||||
In order to use Consul with Nomad, you will need to configure and
|
||||
install Consul on your nodes alongside Nomad, or schedule it as a system job.
|
||||
Nomad does not currently run Consul for you.
|
||||
|
||||
To enable Consul integration, please see the
|
||||
[Nomad agent Consul integration](/docs/configuration/consul.html)
|
||||
configuration.
|
||||
|
||||
## Automatic Clustering with Consul
|
||||
|
||||
Nomad servers and clients will be automatically informed of each other's
|
||||
existence when a running Consul cluster already exists and the Consul agent is
|
||||
installed and configured on each host. Please see the [Automatic Clustering with
|
||||
Consul](/guides/operations/cluster/automatic.html) guide for more information.
|
||||
|
||||
## Service Discovery
|
||||
|
||||
Nomad schedules workloads of various types across a cluster of generic hosts.
|
||||
Because of this, placement is not known in advance and you will need to use
|
||||
service discovery to connect tasks to other services deployed across your
|
||||
cluster. Nomad integrates with Consul to provide service discovery and
|
||||
monitoring.
|
||||
|
||||
To configure a job to register with service discovery, please see the
|
||||
[`service` job specification documentation][service].
|
||||
|
||||
## Dynamic Configuration
|
||||
|
||||
Nomad's job specification includes a [`template` stanza](/docs/job-specification/template.html)
|
||||
that utilizes a Consul ecosystem tool called [Consul Template](https://github.com/hashicorp/consul-template). This mechanism creates a convenient way to ship configuration files
|
||||
that are populated from environment variables, Consul data, Vault secrets, or just
|
||||
general configurations within a Nomad task.
|
||||
|

For more information on Nomad's template stanza and how it leverages Consul Template,
|
||||
please see the [`template` job specification documentation](/docs/job-specification/template.html).
|
||||
|
||||
## Assumptions
|
||||
|
||||
- Consul 0.7.2 or later is needed for `tls_skip_verify` in HTTP checks.
|
||||
|
||||
- Consul 0.6.4 or later is needed for using the Script checks.
|
||||
|
||||
- Consul 0.6.0 or later is needed for using the TCP checks.
|
||||
|
||||
- The service discovery feature in Nomad depends on operators making sure that
|
||||
the Nomad client can reach the Consul agent.
|
||||
|
||||
- Tasks running inside Nomad also need to reach out to the Consul agent if
|
||||
they want to use any of the Consul APIs. Ex: A task running inside a docker
|
||||
container in the bridge mode won't be able to talk to a Consul Agent running
|
||||
on the loopback interface of the host since the container in the bridge mode
|
||||
has its own network interface and doesn't see interfaces on the global
|
||||
network namespace of the host. There are a couple of ways to solve this, one
|
||||
way is to run the container in the host networking mode, or make the Consul
|
||||
agent listen on an interface in the network namespace of the container.

#### Upgrading to Raft Protocol 3
|
||||
|

This section provides details on upgrading to Raft Protocol 3 in Nomad 0.8 and higher. Raft protocol version 3 requires Nomad running 0.8.0 or newer on all servers in order to work. See [Raft Protocol Version Compatibility](/docs/upgrade/upgrade-specific.html#raft-protocol-version-compatibility) for more details. Also the format of `peers.json` used for outage recovery is different when running with the latest Raft protocol. See [Manual Recovery Using peers.json](/guides/outage.html#manual-recovery-using-peers-json) for a description of the required format.

Also the format of `peers.json` used for outage recovery is different when running with the latest Raft protocol. See [Manual Recovery Using peers.json](/guides/operations/outage.html#manual-recovery-using-peers-json) for a description of the required format.
|
||||
|
||||
Please note that the Raft protocol is different from Nomad's internal protocol as shown in commands like `nomad server members`. To see the version of the Raft protocol in use on each server, use the `nomad operator raft list-peers` command.
|
||||
|
||||
The easiest way to upgrade servers is to have each server leave the cluster, upgrade its `raft_protocol` version in the `server` stanza, and then add it back. Make sure the new server joins successfully and that the cluster is stable before rolling the upgrade forward to the next server. It's also possible to stand up a new set of servers, and then slowly stand down each of the older servers in a similar fashion.
|
||||
|
||||
When using Raft protocol version 3, servers are identified by their `node-id` instead of their IP address when Nomad makes changes to its internal Raft quorum configuration. This means that once a cluster has been upgraded with servers all running Raft protocol version 3, it will no longer allow servers running any older Raft protocol versions to be added. If running a single Nomad server, restarting it in-place will result in that server not being able to elect itself as a leader. To avoid this, either set the Raft protocol back to 2, or use [Manual Recovery Using peers.json](/guides/outage.html#manual-recovery-using-peers-json) to map the server to its node ID in the Raft quorum configuration.

Nomad supports multi-datacenter and multi-region configurations. A single region is able to service multiple datacenters, and all servers in a region replicate their state between each other. In a multi-region configuration, there is a set of servers per region. Each region operates independently and is loosely coupled to allow jobs to be scheduled in any region and requests to flow transparently to the correct region.
|
||||
|
||||
When ACLs are enabled, Nomad depends on an "authoritative region" to act as a single source of truth for ACL policies and global ACL tokens. The authoritative region is configured in the [`server` stanza](/docs/agent/configuration/server.html) of agents, and all regions must share a single authoritative source. Any ACL policies or global ACL tokens are created in the authoritative region first. All other regions replicate ACL policies and global ACL tokens to act as local mirrors. This allows policies to be administered centrally, and for enforcement to be local to each region for low latency.

The authoritative region is configured in the [`server` stanza](/docs/configuration/server.html) of agents, and all regions must share a single authoritative source. Any ACL policies or global ACL tokens are created in the authoritative region first. All other regions replicate ACL policies and global ACL tokens to act as local mirrors. This allows policies to be administered centrally, and for enforcement to be local to each region for low latency.
|
||||
|
||||
Global ACL tokens are used to allow cross region requests. Standard ACL tokens are created in a single target region and not replicated. This means if a request takes place between regions, global tokens must be used so that both regions will have the token registered.

## Multi-Region Configuration
|
||||
|
||||
Nomad supports multi-datacenter and multi-region configurations. A single region is able to service multiple datacenters, and all servers in a region replicate their state between each other. In a multi-region configuration, there is a set of servers per region. Each region operates independently and is loosely coupled to allow jobs to be scheduled in any region and requests to flow transparently to the correct region.
|
||||
|
||||
When ACLs are enabled, Nomad depends on an "authoritative region" to act as a single source of truth for ACL policies, global ACL tokens, and Sentinel policies. The authoritative region is configured in the [`server` stanza](/docs/agent/configuration/server.html) of agents, and all regions must share a single authoritative source. Any Sentinel policies are created in the authoritative region first. All other regions replicate Sentinel policies, ACL policies, and global ACL tokens to act as local mirrors. This allows policies to be administered centrally, and for enforcement to be local to each region for low latency.

## What is Nomad?
|
||||
|
||||
Nomad is a tool for managing a cluster of machines and running applications
|
||||
Nomad is a flexible container orchestration tool that enables an organization to
|
||||
easily deploy and manage any containerized or legacy application using a single,
|
||||
unified workflow. Nomad can run a diverse workload of Docker, non-containerized,
|
||||
microservice, and batch applications, and generally offers the following benefits
|
||||
to developers and operators:
|
||||
|
||||
* **API-driven Automation**: Workload placement, scaling, and upgrades can be
|
||||
automated, simplifying operations and eliminating the need for homegrown tooling.
|
||||
* **Self-service Deployments**: Developers are empowered to service application
|
||||
lifecycles directly, allowing operators to focus on higher value tasks.
|
||||
* **Workload Reliability**: Application, node, and driver failures are handled
|
||||
automatically, reducing the need for manual operator intervention
|
||||
* **Increased Efficiency and Reduced Cost**: Higher application densities allow
|
||||
operators to reduce fleet sizes and save money.
|
||||
|
||||
Nomad is trusted by enterprises from a range of sectors including financial,
|
||||
retail, software, and others to run production workloads at scale across private
|
||||
infrastructure and the public cloud.
|
||||
|
||||
## How it Works
|
||||
|
||||
At its core, Nomad is a tool for managing a cluster of machines and running applications
|
||||
on them. Nomad abstracts away machines and the location of applications,
|
||||
and instead enables users to declare what they want to run and Nomad handles
|
||||
where they should run and how to run them.

|
||||
|
||||
## How Nomad Compares to Other Tools
|
||||
|
||||
Nomad differentiates from related tools by virtue of its **simplicity**, **flexibility**,
|
||||
**scalability**, and **high performance**. Nomad's synergy and integration points with
|
||||
HashiCorp Terrform, Consul, and Vault make it uniquely suited for easy integration into
|
||||
an organization's existing workflows, minimizing the time-to-market for critical initiatives.

# Use Cases
|
||||
|
||||
Before understanding use cases, it's useful to know [what Nomad is](/intro/index.html).
|
||||
This page lists some concrete use cases for Nomad, but the possible use cases are
|
||||
much broader than what we cover.
|
||||
This page lists Nomad's core use cases. Please note that the full range of potential
|
||||
use cases is much broader than what is currently covered here. Reading through the
|
||||
[Introduction to Nomad](/intro/index.html) is highly recommended before diving into
|
||||
the use cases.
|
||||
|
||||
## Microservices Platform
|
||||
## Docker Container Management
|
||||
|
||||
Microservices, or Service Oriented Architectures (SOA), are a design paradigm in which many
|
||||
services with narrow scope, tight state encapsulation, and API driven interfaces interact together
|
||||
to form a larger application. However, they add an operational challenge of managing hundreds
|
||||
or thousands of services instead of a few large applications. Nomad provides a platform for
|
||||
managing microservices, making it easier to adopt the paradigm.
|
||||
Organizations are increasingly moving towards a Docker centric workflow for
|
||||
application deployment and management. This transition requires new tooling
|
||||
to automate placement, perform job updates, enable self-service for developers,
|
||||
and to handle failures automatically. Nomad supports a [first-class Docker workflow](/docs/drivers/docker.html)
|
||||
and integrates seamlessly with [Consul](/guides/operations/consul-integration/index.html)
|
||||
and [Vault](/guides/operations/vault-integration/index.html) to enable a complete solution
|
||||
while maximizing operational flexibility. Nomad is easy to use, can scale to
|
||||
thousands of nodes in a single cluster, and can easily deploy across private data
|
||||
centers and multiple clouds.
|
||||
|
||||
## Hybrid Cloud Deployments
|
||||
## Legacy Application Deployment
|
||||
|
||||
Nomad is designed to handle multi-datacenter and multi-region deployments and is cloud agnostic.
|
||||
This allows Nomad to schedule in private datacenters running bare metal, OpenStack, or VMware
|
||||
alongside an AWS, Azure, or GCE cloud deployment. This makes it easier to migrate workloads
|
||||
incrementally, or to utilize the cloud for bursting.
|
||||
A virtual machine based application deployment strategy can lead to low hardware
|
||||
utlization rates and high infrastructure costs. While a Docker-based deployment
|
||||
strategy can be impractical for some organizations or use cases, the potential for
|
||||
greater automation, increased resilience, and reduced cost is very attractive.
|
||||
Nomad natively supports running legacy applications, static binaries, JARs, and
|
||||
simple OS commands directly. Workloads are natively isolated at runtime and bin
|
||||
packed to maximize efficiency and utilization (reducing cost). Developers and
|
||||
operators benefit from API-driven automation and enhanced reliability for
|
||||
applications through automatic failure handling.
|
||||
|
||||
## Microservices
|
||||
|
||||
Microservices and Service Oriented Architectures (SOA) are a design paradigm in
|
||||
which many services with narrow scope, tight state encapsulation, and API driven
|
||||
communication interact together to form a larger solution. However, managing hundreds
|
||||
or thousands of services instead of a few large applications creates an operational
|
||||
challenge. Nomad elegantly integrates with [Consul](/guides/operations/consul-integration/index.html)
|
||||
for automatic service registration and dynamic rendering of configuration files. Nomad
|
||||
and Consul together provide an ideal solution for managing microservices, making it
|
||||
easier to adopt the paradigm.
|
||||
|
||||
## Batch Processing Workloads
|
||||
|
||||
As data science and analytics teams grow is size and complexity, they increasingly
|
||||
benefit from highly performant and scalable tools that can run batch workloads with
|
||||
minimal operational overhead. Nomad can natively run batch jobs, [parameterized](https://www.hashicorp.com/blog/replacing-queues-with-nomad-dispatch) jobs, and [Spark](https://github.com/hashicorp/nomad-spark)
|
||||
workloads. Nomad's architecture enables easy scalability and an optimistically
|
||||
concurrent scheduling strategy that can yield [thousands of container deployments per
|
||||
second](https://www.hashicorp.com/c1m). Alternatives are overly complex and limited
|
||||
in terms of their scheduling throughput, scalability, and multi-cloud capabilities.
|
||||
|
||||

|
||||
|
||||
## Multi-region and Multi-cloud Deployments
|
||||
|
||||
Nomad is designed to natively handle multi-datacenter and multi-region deployments
|
||||
and is cloud agnostic. This allows Nomad to schedule in private datacenters running
|
||||
bare metal, OpenStack, or VMware alongside an AWS, Azure, or GCE cloud deployment.
|
||||
This makes it easier to migrate workloads incrementally and to utilize the cloud
|
||||
for bursting.
|
||||
|
||||
## E-Commerce
|
||||
|
||||
A typical E-Commerce website has a few types of workloads. There are long-lived services
|
||||
used for web serving. These include the load balancer, web frontends, API servers, and OLTP databases.
|
||||
Batch processing using Hadoop or Spark may run periodically for business reporting, user targeting,
|
||||
or generating product recommendations. Nomad allows all these workloads to share an underlying cluster,
|
||||
increasing utilization, reducing cost, simplifying scaling and providing a clean abstraction
|
||||
for developers.
