What are the different types of service discovery?
There are two main service‑discovery patterns: client-side discovery and service-side discovery. In systems that use client‑side service discovery, clients query the service registry, select an available instance, and make a request.
What is DNS in microservices?
DNS provides an easy way to connect microservices to the load balancer. You can configure a hostname for each microservice, register it on a DNS server and associate the hostname with the load balancer’s DNS name using a CNAME entry.
What is the primary purpose of having a service 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 service discovery and how you implement?
What is the purpose of Istio?
Istio enables organizations to secure, connect, and monitor microservices, so they can modernize their enterprise apps more swiftly and securely. Istio manages traffic flows between services, enforces access policies, and aggregates telemetry data, all without requiring changes to application code.
How is client side discovery used in microservices architecture?
Let’s first look at client-side discovery. When using client-side discovery, the client is responsible for determining the network locations of available service instances and load balancing requests across them. The client queries a service registry, which is a database of available service instances.
What are the two main service discovery patterns?
There are two main service discovery patterns: client-side discovery and server-side discovery. Let’s first look at client-side discovery. When using client-side discovery, the client is responsible for determining the network locations of available service instances and load balancing requests across them.
What are the benefits of client side discovery?
Client-side discovery has the following benefits: Client-side discovery also has the following drawbacks: You need to implement client-side service discovery logic for each programming language/framework used by your application, e.g Java/Scala, JavaScript/NodeJS.
What should be included in the client discovery process?
You should gather and assess internal data (e.g. brand / organizational) and external data (e.g. 3rd party surveys, white papers, reports) data on consumer or business trends, markets, stakeholders, competitors, etc.
