Deploying and managing workloads across multiple clusters has become a complex task
To reduce management efforts, IT teams often seek some automation mechanism
Consul is a service mesh solution to automate network configuration
It is developed by HashiCorp, and was first released in 2014
*What is Consul*
Consul can help discover and connect to services across complex service mesh networks
It can be installed and configured on any existing Kubernetes cluster
Users can automate the configuration of the network middleware with Consul
*Deep Dive*
Consul offers service configuration, discovery, and segmentation capabilities
These capabilities can be used together to build a full-service mesh
Consul is also designed to be cloud native and runs as an independent process.
It can run either on a single node or distributed across multiple nodes.
The consul agent runs as the root process of the system.
Consul is a system which allows administrators to monitor and coordinate the state of their infrastructure.
It enables their applications to work together in an environment that can be partially or fully offline, with eventual consistency at every scale.
It also provides advanced security features to protect these highly-available services from downtime, data corruption, and denial-of-service attacks.
*Key features*
The key features of Consul include:
health checking: It is used to monitor the health of applications and help identify potential failures before they happen.
service discovery: Consul watches the network for new services and allows registering and deregistering services using DNS Service Discovery (DNS-SD)
KV store (to store key-value pairs): provides a flexible way to share configuration data between nodes, groups of nodes, or an entire organization.
Multi-datacenter management: The Consul architecture helps each datacenter to run independently preventing failures from impacting availability
secure service communication: With the use of encryption and authorization Consul provides secure service communication
It also supports third-party proxy, like Envoy and native integration models
If you are looking for a reliable and scalable mesh to help your application developers and the DevOps community, Consul is the way to go.
