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.

Throughout this tutorial, we will cover some of the fundamentals of indexing. As part of the MySQL series, we will introduce capabilities of MySQL indexing and the role it plays in optimizing database performance. Liquid Web recommends consulting with a DBA before making any changes to your production level application.

In some ways, firewalld on systemd systems is easier to manage and configure than iptables. There are, for the most part, no long series of chains, jumps, accepts and denies that you need to memorize to get firewalld up and running in a basic configuration. The rules are simple and straightforward, but there is no reason you cannot still have all the power that iptables afforded.

Every MySQL backed application can benefit from a finely tuned database server. The Liquid Web Heroic Support team has encountered numerous situations over the years when some minor adjustments have made a world of difference in website and application performance. In this series of articles, we have outlined some of the more common recommendations that have had the largest impact on performance.

A Squid Proxy Server is a feature-rich web server application that provides both reverse proxy services and caching options for websites. This provides a noticeable speedup of sites and allows for reduced load times when being utilized.

Apache by default logs data directly to log files. While this isn't a bad thing, it is not your only option. Both Apache 1.x and Apache 2.x bring with them the option of enabling something called "Piped Logging", though cPanel will only allow you to enable it for version 2.x.

Before we get into the details of Apache tuning, we need to understand what happens when a VPS server or Dedicated server goes unresponsive due to a poorly optimized configuration.

When looking to host websites or services from a Windows server, there are several options to consider. It is worth reviewing the strengths and weaknesses of each server type to determine which one is most likely to meet your particular needs before you spend the time installing and configuring a web service.

Configuration management is the process by which a company or organization defines and tracks the state of its infrastructural resources. Encapsulated in those resources are both physical hardware and software. It is a means to ensure that when changes are made to a system, those changes are tracked, geared toward the ultimate predefined criteria of what state should be.

One of the nice things about cPanel-based servers is the way that they keep the location of key files in the same place across all the various cPanel versions.  Due to this consistency one always knows where to look for logs files for all services running on a cPanel server.
