Kubernetes vs. Docker Swarm: A Comparison

Reading Time: 5 minutes

In this tutorial, we will be reviewing what the fundamental similarities and distinctions are between Kubernetes and Docker Swarm. Kubernetes and Docker are two of the major players in container orchestration. Both Kubernetes and Docker Swarm continue to grow in popularity as they are increasingly used by those working with container deployment, orchestration, and management. Across all vertical markets, businesses continue to find new methods of utilization and practice with more uses constantly being discovered.

How to Install and Use Containerization

Reading Time: 6 minutes

What is Containerization?

Containerization is a form of virtualized operating system developed as a response to the many problems of hardware-level virtualization. Because the latter runs a full-blown guest operating system, it is very resource-intensive and incurs a significant amount of overhead, but containerization is much lighter. Since the containers share the host machine’s kernel, the resources are not wasted on running separate operating system tasks. This allows for a much quicker and lightweight deployment of applications.

Service Mesh Defined: A Simple Overview

Reading Time: < 1 minute

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.

How is a Service Mesh Achieved?

Typically, a service mesh is implemented via sidecars. These sidecars are usually attached to every microservice on your network. The service mesh abstracts communication between microservices into these sidecars and the sidecars communicate with one another in a mesh topology.

Because most modern apps are now smaller than their predecessors, they have shrunken the communication logic written into each app, microservice, function, etc. With one or two microservices, or maybe even a dozen, the communication logic generally isn’t difficult to deal with. At scale, or when you have hundreds of such apps, a service mesh can be thought of as ‘required’.

So, a service mesh consists of the following components:

  • A communication layer of control between apps or microservices
  • The network stack they typically communicate over
  • Abstracts communication and implements ‘sidecars’ with every microservice

Git & Continuous Deployment on Cloud Sites

Reading Time: 2 minutes

If you’re used to using services such as GitHub or Bitbucket for continuous integration, chances are you’re wondering how you can setup continuous deployment for your website on Cloud Sites. Since Cloud Sites doesn’t have git or SSH access, you might think it’s impossible. Luckily, with a service like DeployBot and their SFTP deployment tools, it is actually very simple to deploy your code from your repository to Cloud Sites with a simple click. Here’s a quick tour on how to get up and running with DeployBot and Cloud Sites.

Creating a new site on Cloud Sites

If you haven’t done so already, you’ll first want to create your website on Cloud Sites. Once logged into your Cloud Sites dashboard, simply click on Create Website, input your domain name, choose your Framework, and then click on Create New Website.
