What is Microservice discovery?
Service discovery is how applications and (micro)services locate each other on a network. Implementations include both a central server(s) that maintain a global view of addresses and clients that connect to the central server to update and retrieve addresses.
What is Hashicorp consul used for?
Consul is a full-featured service mesh solution that solves the networking and security challenges of operating microservices and cloud infrastructure. Consul offers a software-driven approach to routing and segmentation. It also brings additional benefits such as failure handling, retries, and network observability.
What is service discovery used for?
Service discovery is the automatic detection of devices and services offered by these devices on a computer network. A service discovery protocol (SDP) is a network protocol that helps accomplish service discovery. Service discovery aims to reduce the configuration efforts required by users and administrators.
Why do we need service discovery in microservices?
In a microservices application, the set of running service instances changes dynamically. Instances have dynamically assigned network locations. Consequently, in order for a client to make a request to a service it must use a service‑discovery mechanism. The service registry provides a management API and a query API.
Who uses Consul?
Who uses Consul? 262 companies reportedly use Consul in their tech stacks, including Slack, Robinhood, and LaunchDarkly.
Is Consul a load balancer?
Consul is a free and open source tool that provides service discovery, health checking, load balancing, and a globally distributed key-value store.
Which is the best open source service discovery tool?
Consul is a highly distributed service discovery tool. It can act as a key-value store for configuration management. Serf (gossip protocol) is used to manage everything in the cluster like failure detection. Another consensus protocol called Raft manages consistency within the system.
Why is service discovery so important in microservice?
With evolving microservice architecture, service discovery is becoming a must-have for all modern applications. New components that get deployed should be able to find other service endpoints very efficiently without much latency. Service discovery paves a way for this.
What is the difference between service registration and service discovery?
Service Registration and Service Discovery. Service Registration – The process of a service registering its location in a central registry. It usually register its host and port and sometimes authentication credentials, protocols, versions numbers, and/or environment details.
How is serf a decentralized service discovery solution?
Serf is a decentralized solution for service discovery and orchestration. It is also written in Go and is unique in that uses a gossip based protocol, SWIM for membership, failure detection and custom event propogation. SWIM was designed to address the unscalability of traditional heart-beating protocols.
