# What is a Service Mesh?
# What is a service mesh?
A _service mesh_ is a dedicated network layer that provides secure service-to-service communication within and across infrastructure, including on-premises and cloud environments.
Service meshes are often used with a microservice architectural pattern, but can provide value in any scenario where complex networking is involved.

# What is Service Discovery?
# What is service discovery?
_Service discovery_ helps you discover, track, and monitor the health of services within a network. Service discovery registers and maintains a record of all your services in a _service catalog_. This service catalog acts as a single source of truth that allows your services to query and communicate with each other.

## What is Service Discovery in Microservices?
## What is service discovery in microservices?
In a microservices application, the set of active service instances changes frequently across a large, dynamic environment. These service instances rely on a service catalog to retrieve the most up-to-date access information from the respective services. A reliable service catalog is especially important for service discovery in microservices to ensure healthy, scalable, and highly responsive application operation.

For modern applications, this discovery method is advantageous because developers can make their applications faster and more lightweight by decoupling and centralizing service discovery logic.
## Service Discovery vs Load Balancing
## Service discovery vs load balancing
Service discovery and load balancing share a similarity in distributing requests to back end services, but differ in many important ways.

For modern, cloud-based applications, service discovery is the preferred method for directing traffic to the right service provider due to its ability to scale and remain resilient, independent of infrastructure.
## How do you implement Service Discovery?
## How do you implement service discovery?
You can implement service discovery systems across any type of infrastructure, whether it is on-premise or in the cloud. Service discovery is a native feature of many container orchestrators such as Kubernetes or Nomad. There are also platform-agnostic service discovery methods available for non-container workloads such as VMs and serverless technologies. Implementing a resilient service discovery system involves creating a set of servers that maintain and facilitate service registry operations. You can achieve this by installing a service discovery system or using a managed service discovery service.
