How To Install HashiCorp Consul
Hello Everyone
Welcome to CloudAffaire and this is Debjeet.
In today’s blog post, we will discuss how to install HashiCorp Consul. Consul is a service mesh solution that interconnects different services in your application and provides a control plane with service discovery, configuration and segmentation functionality for your application. Below is the key features of HashiCorp Consul.
Key Features Of HashiCorp Consul:
- Service Discovery: Consul clients can register a service like api or mysql, and other clients can use Consul to find providers of a particular service. With DNS or HTTP, applications can easily find the services they depend on.
- Health Checking: Consul clients can perform any number of health checks that are connected to a specific service (“web server returns 200 OK”) or to the local node (“memory usage is less than 90%”). An operator can use this information to monitor the health of the cluster, and it is used by service discovery components to divert traffic from failing hosts.
- Key Value Store: Applications can use the Consul hierarchical keystore / value for any number of purposes, including dynamic configuration, feature flagging, coordination, leader selection, and more. Simple HTTP API makes it easy to use.
- Secure Service Communication: Consul can generate and distribute TLS certificates for services to establish TLS interconnections. Intentions can be used to determine which services can communicate. Service segmentation can be easily managed with intentions that can be changed in real time, rather than using complex network topologies and static firewall rules.
- Multi Datacenter: Consul supports multiple datacenters out of the box. This means users of Consul do not have to worry about building additional layers of abstraction to grow to multiple regions.
