Misjudging incoming traffic can overload your web servers. Load balancers like HAProxy (High Availability Proxy) can help alleviate that issue. The primary job of load balancers is to balance the load on the server by minimizing response times, optimizing the usage of your resources, and improving the performance of your multi-server configuration

What is Service Mesh?

A service mesh is an additional infrastructure layer that provides a means of communication between all services in a given application. It is typically deployed as a series of proxies alongside each service instance. Since the service mesh proxies are deployed alongside the application services and not as part of it, they are often referred to as sidecars. This means that as a whole, these sidecar proxies are a mesh network and an infrastructure layer separate from the application. A service mesh not only brokers communication between all services in an application but, since all requests, both internal and external, pass through it, it provides a means for handling many tasks that can be obfuscated away from the application.

Introduction

All online businesses need to account for growth. As a business receives more visitors to its site, the underlying infrastructure needs to scale to provide the same level of performance that the visitors are accustomed to. Horizontal scaling, the addition of more servers rather than increasing the power of the existing servers, is an easy way to build our web servers' ability to handle a more significant amount of traffic and protect us against hardware failure. Ensuring that the additional web servers have the same files and data is a potentially time-consuming and challenging task. Automating that task using free, open-source software, such as lsyncd, is a way to ensure that we have a safe, secure, and repeatable method of copying files from one server to another.

Load balancing and replicating multiple servers has a great array of benefits, though orchestrating and keeping them in sync can be very tricky. Here, we will walk through some of the load balancing options available, as well as setting up a very basic one-way replication sync between two or more servers behind a load balancer.

What is a Service Mesh?

A service mesh is a layer of communication and control between applications or microservices and the network stack they typically communicate over. This layer controls communication and helps microservices share data. This service-to-service interaction is governed by logic built into the service mesh layer. Simply put, microservices are small or partial applications, or individual functions, and the network stack is the physical networking layer.

Load balancing is the distribution of a workload across many nodes. In the web hosting industry, it is typically used for balancing HTTP traffic over multiple servers acting together as a web front-end. For the sake of this article, we will focus on the balancing of HTTP and HTTPS traffic through a Zeus Load Balancer.
