Consul vs OpenStack: 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, OpenStack is detailed as "Open source software for building private and public clouds". OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface.

Consul belongs to "Open Source Service Discovery" category of the tech stack, while OpenStack can be primarily classified under "Open Source Cloud".

Some of the features offered by Consul are:

  • Service Discovery - Consul makes it simple for services to register themselves and to discover other services via a DNS or HTTP interface. External services such as SaaS providers can be registered as well.
  • Health Checking - Health Checking enables Consul to quickly alert operators about any issues in a cluster. The integration with service discovery prevents routing traffic to unhealthy hosts and enables service level circuit breakers.
  • Key/Value Storage - A flexible key/value store enables storing dynamic configuration, feature flagging, coordination, leader election and more. The simple HTTP API makes it easy to use anywhere.

On the other hand, OpenStack provides the following key features:

  • Compute
  • Storage
  • Networking

"Great service discovery infrastructure" is the top reason why over 49 developers like Consul, while over 35 developers mention "Private cloud" as the leading cause for choosing OpenStack.

Consul is an open source tool with 16.4K GitHub stars and 2.85K GitHub forks. Here's a link to Consul's open source repository on GitHub.

According to the StackShare community, Consul has a broader approval, being mentioned in 134 company stacks & 55 developers stacks; compared to OpenStack, which is listed in 67 company stacks and 50 developer stacks.

      What are some alternatives to Consul and OpenStack?
      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.

      All our services use Consul for discovery, configuration and cluster management (auto scaling, health monitoring, dynamic reconfiguration, leader elections)
