Alternatives to Azure Kubernetes Service (AKS): Azure App Services

November 9, 2020

app-service-iconYou can run your web applications in Azure App Service in a fully managed service using either Windows and Linux-based containers. You may not need the overhead of a Kubernetes deployment. App Services provides security, load balancing, autoscaling, and automated management.

In addition, App Services has DevOps capabilities, such as continuous deployment from Azure DevOps, GitHub, Docker Hub, and other sources, package management, staging environments, custom domain, and TLS/SSL certificates.

By fully-managed, we mean App Service automatically patches and maintains the OS and language frameworks for you. Spend time writing great apps and let Azure worry about the platform.

With App Services Environment, deploy your application within a virtual network you define where you can have fine-grained control over inbound and outbound application network traffic.

Alternatives to Azure Kubernetes (AKS): Azure Container Instances

November 6, 2020

You may want to use containers for your deployments to Azure, but you may not want all the complexities of either standing up your own Kubernetes cluster on premises or Azure Kubernetes Service (AKS). For example, you may want to run a container for a short time.

Azure Container Instance have fast startup times, can be accessed using an IP address or a fully qualified domain name (FQDN). You can customize the size, use either Linux or Windows containers. You can schedule Linux containers to use NVIDIA Tesla GPU resources (preview).

Let’s learn more about Azure Container Instances.

Understand the architecture of Kubernetes

November 3, 2020

Kubernetes is a portable, extensible, open-source platform for managing you containerized workloads and services. Kubernetes architecture takes care of scaling and failover of your applications running on a container.

In this post, you will learn about Kubernetes Control Plane Components and the Node Components and how they work together. You will learn about how a pod hosts multiple containers, how multiple pods are in a node, how several nodes are included in a cluster, and how Kubernetes uses a control plane to keep track of what is happening in a cluster.

In short, you will understand the architecture of Kubernetes.

Understand microservices, containers, Kubernetes

November 2, 2020

In this post, learn how microservices, containers, and Kubernetes are all related. One is an architecture, one is a deployment mechanism, and one orchestrates how those deployments will function in production.

A microservice is a program that runs on a server or a virtual computer and responds to some request. Microservices give you a way to build applications that are resilient, highly scalable, independently deployable, and able to evolve quickly.

Microservices have a more narrow scope and focus on doing smaller tasks well.

A container is just a process spawned from an executable file, running on a Linux machine, which has some restrictions applied to it.

Kubernetes (aka, K8s) help you increase your infrastructure utilization through the efficient sharing of computing resources across multiple processes. Kubernetes is the master of dynamically allocating computing resources to fill the demand. The side benefits of K8s that make the transition to microservices much easier.

Let’s see how that works.

Get acquainted with Kubernetes

November 2, 2020

Kubernetes (K8s) is an open-source system for automating deployment, scaling, and management of containerized applications. Kubernetes, pronounced “koo-ber-net-eez,” the name is Greek for “helmsman of a ship.” Build, deliver, and scale containerized apps faster with Kubernetes, sometimes referred to as “k8s”

In this blog, you explore what Kubernetes is, the advantages and disadvantages.

Let’s start with some definitions.

View and register resource providers

September 17, 2020

Microsoft.VisualStudio.Services.IconsJust because Azure provides a resource, you may not have access to it in your subscription. You may have to add a particular resource.

You can think of a resource provider as a way Azure (ugh) provides resources. Another way to think about resource provides is that they are the services provided by a resource. For example, a resource provider offers a resource type called vaults for creating the key vault.

Each provider has one or more resource types. The name of a resource type is in the format: {resource-provider}/{resource-type}. The resource type for a key vault is Microsoft.KeyVault/vaults.

Organize Azure resources in resource groups using portal, PowerShell, Azure CLI

September 15, 2020

Microsoft.VisualStudio.Services.IconsWhen you create, update, and delete resources in Azure you are using the Azure Resource Manager (ARM). Azure Resource Manager provides access control, tagging, auditing of your resources.

In this article, you use the portal, PowerShell, the Azure Command Line Interface (CLI) to create, manage access and delete resources. Links are provided in the reference section of this chapter for you to learn how to manage resources using the REST API.

You create resources in either an imperative way by describing each of the steps and feature with scripts. In a following post, you will learn how to create resources using a declarative syntax with an ARM template to describe the features and properties.

Walkthrough on how to handle merge conflicts in Git

July 21, 2020

Git-Logo-2ColorGit is distributed version control system designed to handle everything from small to very large projects with speed and efficiency.The foundation of DevOps, begins with using source code control. This includes the source control for your Infrastructure as Code.But sometimes, when you check in your code, either you or someone else has been working made a change that creates a conflict between branches.

When the same part of the same file in two branches have been changed, Git won’t be able to figure out which version to use. When such a situation occurs, Git stope your right before the merge commit, where you will need to resolve the conflicts manually.

In this walkthrough, you set up a new repository, make changes to the repository where so changes conflict with those on your local machine, merge the changes, and push the changes to the repository.

Cheatsheet and best practices for Git

July 16, 2020

Git-Logo-2Color

Git is distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

Git is a primary tool for both developers and cloud engineers who are moving to infrastructure as code. Git is the core of a modern version control software, which keeps track of every modification to the code in a special kind of database. If (dare I say “when”) a mistake is made, you can turn back the clock and compare earlier versions of the code to help fix the mistake while minimizing disruption to all team members.

You do not need to have your repository set up to get started with Git. Although you will want to set one up to save your changes and to manage your deployments. Learn more about how to set up your repositories in the previous post.

In this article, you will find a list of resources to use to learn how to get started with Git.  The article provides some sample command in a pattern you will use for your code or your infrastructure as a code. There are also references on how to get started learning Git.

Or .. if you prefer you can use the Git Cheatsheet from GitHub. The contribution made in this blog post is to show you common patterns you will use daily.

Set up Git with repository on GitHub or Azure DevOps Repos

July 14, 2020

github
In setting up our production environments, we’re started to get some code that we will want to backup, save, reuse, make changes, and share with others. We will want collaborate. And a source control system is idea for all this.

Git is distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

Git is a primary tool for both developers and cloud engineers who are moving to infrastructure as code. In our next post you will learn more about Git workflows. But first, because our blog is related to enterprise production, you will you will want to set up a repository for your code.

The purpose of this article is to provide the steps to get set up and provide the steps for some common scenarios for both GitHub and Azure DevOps so you can get started checking in code.
