Consul vs Nomad: What are the differences?

Developers describe Consul as "A tool for service discovery, monitoring and configuration". Consul is a tool for service discovery and configuration. Consul is distributed, highly available, and extremely scalable. On the other hand, Nomad is detailed as "A cluster manager and scheduler". Nomad is a cluster manager, designed for both long lived services and short lived batch processing workloads. Developers use a declarative job specification to submit work, and Nomad ensures constraints are satisfied and resource utilization is optimized by efficient task packing. Nomad supports all major operating systems and virtualized, containerized, or standalone applications.

Consul can be classified as a tool in the "Open Source Service Discovery" category, while Nomad is grouped under "Cluster Management".

Consul and Nomad are both open source tools. Consul with 16.2K GitHub stars and 2.82K forks on GitHub appears to be more popular than Nomad with 4.86K GitHub stars and 882 GitHub forks.

According to the StackShare community, Consul has a broader approval, being mentioned in 131 company stacks & 52 developers stacks; compared to Nomad, which is listed in 21 company stacks and 3 developer stacks.

Breaking a monolith into microservices and handling the scaling and health of new services as they come only. This should ideally help to reduce the overhead needed to get a service online. We have all of this being handled by custom URLs and health checks being done at the expense of infrastructure setup time and maintenance (VM sprawl). Initially, I am looking at Consul for the TLS proxy and security options as well as the KV store which may prove useful in cross datacenter environments.

    What are some alternatives to Consul and Nomad?
    etcd
    etcd is a distributed key value store that provides a reliable way to store data across a cluster of machines. It’s open-source and available on GitHub. etcd gracefully handles master elections during network partitions and will tolerate machine failure, including the master.
    Zookeeper
    A centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. All of these kinds of services are used in some form or another by distributed applications.
    SkyDNS
    SkyDNS is a distributed service for announcement and discovery of services. It leverages Raft for high-availability and consensus, and utilizes DNS queries to discover available services. This is done by leveraging SRV records in DNS, with special meaning given to subdomains, priorities and weights (more info here: http://blog.gopheracademy.com/skydns).
    Ambassador
    Map services to arbitrary URLs in a single, declarative YAML file. Configure routes with CORS support, circuit breakers, timeouts, and more. Replace your Kubernetes ingress controller. Route gRPC, WebSockets, or HTTP.
    Kubernetes
    Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions.
