Load Balancing

Introduction> Introduction # Let’s Encrypt is a new Certificate Authority (CA) that provides an easy way to obtain and install free TLS/SSL certificates, thereby enabling encrypted HTTPS on web servers. It simplifies the process by providing a software client, Certbot, that attempts to automate most of the required steps.

Introduction> Introduction # This tutorial will demonstrate how you can use Corosync and Pacemaker with a Reserved IP to create a high availability (HA) server infrastructure on DigitalOcean. Corosync is an open source program that provides cluster membership and messaging capabilities, often referred to as the messaging layer, to client servers.

Introduction> Introduction # High availability is a function of system design that allows an application to automatically restart or reroute work to another capable system in the event of a failure.

Introduction> Introduction # In this tutorial, we will teach you how to use HAProxy as a layer 4 load balancer for your WordPress servers–specifically the web application tier. Load balancing the application servers adds redundancy to your setup, which increases reliability in case of server failures or networking issues, and spreads the load across multiple servers for increased read performance.

Status: Deprecated> Status: Deprecated # This article covers a version of Ubuntu that is no longer supported. If you are currently operate a server running Ubuntu 12.04, we highly recommend upgrading or migrating to a supported version of Ubuntu:

Introduction> Introduction # Heartbeat is an open source program that provides cluster infrastructure capabilities—cluster membership and messaging—to client servers, which is a critical component in a high availability (HA) server infrastructure.

Introduction> Introduction # In this guide, we will discuss Nginx’s http proxying capabilities, which allow Nginx to pass requests off to backend http servers for further processing. Nginx is often set up as a reverse proxy solution to help scale out infrastructure or to pass requests to other servers that are not designed to handle large client loads.

Introduction> Introduction # CoreOS allows you to easily run services in Docker containers across a cluster of machines. The procedure for doing so usually involves starting one or multiple instances of a service and then registering each instance with etcd, CoreOS’s distributed key-value store.

Introduction> Introduction # This article shows you how to set up Nginx load balancing with SSL termination with just one SSL certificate on the load balancer. This will reduce your SSL management overhead, since the OpenSSL updates and the keys and certificates can now be managed from the load balancer itself.

Introduction> Introduction # Terraform is a tool for building and managing infrastructure in an organized way. You can use it to manage DigitalOcean Droplets, Load Balancers, and even DNS entries, in addition to a large variety of services offered by other providers.

Introduction> Introduction # In this tutorial, we will teach you how to use HAProxy as a layer 7 load balancer to serve multiple applications from a single domain name or IP address.

Introduction> Introduction # Once your application is up and running in a cloud server environment, you may be wondering how you can improve your server environment to make the leap from “it works” to a full-fledged production environment.

Introduction> Introduction # HAProxy, which stands for High Availability Proxy, is a popular open source software TCP/HTTP Load Balancer and proxying solution which can be run on Linux, Solaris, and FreeBSD.

Introduction> Introduction # With an increased demand for reliable and performant infrastructures designed to serve critical systems, the terms scalability and high availability couldn’t be more popular. While handling increased system load is a common concern, decreasing downtime and eliminating single points of failure are just as important.

Introduction> Introduction # A reverse proxy is a type of proxy server that takes HTTP(S) requests and transparently distributes them to one or more backend servers. Reverse proxies are useful because many modern web applications process incoming HTTP requests using backend application servers which aren’t meant to be accessed by users directly and often only support rudimentary HTTP features.

Introduction> Introduction # By default, Jenkins comes with its own built in web server, which listens on port 8080. This is convenient if you run a private Jenkins instance, or if you just need to get something up quickly and don’t care about security.

Introduction> Introduction # Albeit one of the more controversial techniques, a good method to geographically distribute your application by taking advantage of your provider’s global presence is to use and manage DNS responses (i.
