How to unleash the full power of Azure DevOps

Microsoft Azure is the second most significant cloud provider behind Amazon’s AWS. Azure has over 20% of the cloud market share and is gradually catching up with AWS. Azure DevOps is a significant factor that contributed to Microsoft’s success in the cloud space.

Microsoft Azure DevOps offers the capability to deploy the hosted version of the cloud or effortlessly deploy your own data center. Its offerings include a one-stop suite of services to create continuous integration and continuous delivery (CI/CD) pipelines, version control, test case management, and requirements planning and management.

This article details how DevOps engineers can effortlessly cover much of the application lifecycle with the Azure out-of-the-box components.

1. Getting started 

When we pointed out that Azure DevOps technology tools easily integrate, we did not imply that simple out-of-the-box deployment is enough to get the best out of them.

When implementing a new setup on Microsoft Azure DevOps, you need to plan how you will put the elements together. Building a sophisticated pipeline can be much more challenging unless you understand CI/CD principles well. For instance, you must never stack together too many tasks in one stage when deploying an application with Azure DevOps. It leads to troubles when debugging, as all other tasks must be disabled to test a single job. This entire process is not only time-consuming but also frustrating, which defeats the purpose of DevOps.

2. Create proficiency with training 

Azure DevOps is designed to be an off-the-shelf solution. However, when working with sophisticated workflow pipelines, engineers must assemble them in a way that offers a bespoke solution per the organization’s needs.

An easy way to introduce proficiency in your team to handle Azure DevOps better is to provide them with a few weeks of training. In-house software developers and architects might not be fully aware of the capabilities of the DevOps technology that can be deployed with Azure. 

Also, your engineers must be preoccupied with projects which leave them little time or space to explore the full capabilities of Azure DevOps. An in-depth Azure DevOps training with people who have spent time in the trenches and have years of real-world experience can bring your development teams up to speed in no time.

3. Practice “un-deploy”

It would help if you could efficiently get the most out of Microsoft Azure. For this, you have to plan the application deployment in a phased-out manner to highlight the components that do not need to be moved to the cloud. One difference between in-premises hosting vs. cloud migration is that you are charged for everything you use. To cut costs and maximize the use of available Azure resources, you must un-deploy the processes that are not necessary. Also, DevOps engineers should create functional pipelines so that any component can be undeployed if required.

4. Put only the core team into Azure DevOps

Nothing is worse than building a failed deployment, often due to team mismanagement. With Azure DevOps, you can better manage teams reducing such failures. When too many members are working on Azure DevOps, somebody might tweak something without informing the DevOps team. 

However, Azure DevOps has several security features that solve this problem. You can easily manage access to Azure DevOps, permitting only the core DevOps team to deploy. Other engineers and developers on the unit can be part of other Azure DevOps security groups and access their deployments.

5. Maximum strategy and protocol

When you have a strategy in mind, you can always handle any aspect of the project without getting lost down the line. Multiple layers of planning must include different strategies for artifact naming, scaling, monitoring/logging, security, change management, and backups/reliability. It would help if you planned the maximum strategy by involving as many stakeholders as possible such as engineers, DevOps, and QA testers.

This also creates a deployment cadence for team members to have a better overview of the entire Azure project, enabling them to deploy anything, anytime, and in any environment. You must establish a protocol for the DevOps team to follow. Let your team practice the processes you set up on Azure DevOps such that they do not face difficulties later on. As the team starts building the protocol, they will encounter challenges that they have to address and resolve.

Conclusion 

Deploying to the cloud gives businesses an advantage to grow at scale. However, you have to constantly change and improve with the cloud as it makes your services better. If you are using Microsoft Azure, this guide will help you to use Azure DevOps at its full potential. Ensure you are flexible and ready to learn new tools and DevOps technology.

Kubernetes developer toolkit: In-demand skills, learning resources, online courses, interview prep, books & more

Kubernetes is one of the leading container orchestration platforms. Companies prefer Kubernetes for their projects because of its cloud-agnostic approach that efficiently manages workload whether your project resides in the cloud or on-premises. It has freed companies from being locked into the services offered by their cloud provider or managing entire team operations on-premises or virtualization platforms. This is why Kubernetes is one of the most critical technologies in the DevOps domain. In 2021, there were over 3.9 million Kubernetes developers worldwide, which is a 67% increase from the previous year. As the adoption of technology increases, it is a valuable skill to add to your resume. 

This Kubernetes developer toolkit lists the best resources to learn, upskill, and succeed in the industry.

Microservices: Kubernetes developers must know how to develop software applications based on microservices. Even when the programming languages are the same, developing applications for Kubernetes based on modern architecture requires different coding patterns and software release processes.

System administration: Releasing software updates regularly on a Kubernetes hosting platform requires advanced system administration skills. With the traditional approach of deploying code, there is no way to know the scalability flaws unless the software is installed and used by the customers. But the modern software architecture requires developers to learn Linux commands and database queries to test the software in production.

CI/CD: Kubernetes is for hosted applications with continuous integration and continuous delivery (CI/CD) as an integral part. As a Kubernetes developer, you must be familiar with CI/CD tools like Jenkins. You need to know how coding and software deployment steps can be automated. You will be asked about concepts like unit and functional tests, deployment of the Kubernetes pods, and code compilation in a hosted environment.  

API support: You need to be able to create an Application Programming Interface (API) for the software deployed on Kubernetes such that users who want to interact with your hosted application directly can do it. You must know the concepts of API, such as JSON or YAML files. Learn more about tips on creating robust APIs.

Terraform developer toolkit: In-demand skills, learning resources, online courses, interview prep, books & more

Terraform is an infrastructure as a code tool that developers use to define the project resources both on the cloud or on-premise in human-readable configuration files. It makes it easy to reuse and share any code in a native cloud environment. More and more companies are using Terraform to manage the infrastructure and application lifecycle via a consistent workflow. As a DevOps engineer, learning Terraform gives you the skills to handle even the most low-level components of hosted applications like CPU, storage, and networking resources.

Here is a complete Terraform developer toolkit with a list of resources that help you learn, upskill, and prepare for the interviews.

1. Terraform’s Language (HCL): Also called Hashicorp Configuration Language, you must be familiar with the syntax to use Terraform. Here’s an example syntax: 

Terraform_command “provider_resource_name” “resource_name” {

“option_1”: “option_1”,

  “option_1”: “option_1”

}

When you understand the Terraform code’s basic structure, it becomes much easier to use Terraform. Any Terraform code block has four critical elements: Command, Provider Resource Name, and Options.

2. State: One of the most important concepts of Terraform is the State. As a client-based application, Terraform must be able to keep track of the resources that it creates. For this functionality, it uses the concept of state. You must know how to make a State JSON file and use it for resource optimization.

3. Dependency resolution: Creating a cloud infrastructure requires many resources that are created simultaneously. There is an overlapping dependency between these resources that need management. With Terraform, you can quickly identify which resources depend on each other to prepare a well-planned execution strategy. As a Terraform developer, you must know the concept of dependency resolution, which is extremely important to deploy resource updates in the correct order.

4. Infrastructure as Code: Any DevOps engineer will have to ensure that the systems they design are built in a repeatable manner using Infrastructure as Code. It is an essential skill because it is how you can document cloud objects as version-controlled code. You must learn the concepts of IaC to get better opportunities as a Terraform developer.

All About Terraform

Getting Started with Terraform on AWS with Cobus Bernard

Teamwork: DevOps teams work with both developers and operations teams. As part of a DevOps team, you should have a teamwork spirit. Learn to work well with other stakeholders and accommodate their ideas and requirements. Most successful teams are the ones that enable collaboration among members.

Patience: When working as a DevOps engineer, you must have patience. Not everyone will get your idea or the reason behind your decisions immediately. Other developers in your team might need more time to understand things. For this reason, you have to be patient. The operations team might be unable to understand how complex programming is or how long product update releases might take; for such reasons, you should anticipate the need for patience.

Open-mindedness: When you keep your mind open to new ideas, whether yours or someone else’s, you are more approachable and innovative. It would help if you took your time to understand the ideas presented to you before dismissing them. Exploring ideas is how you progress and find new ways to solve a challenge.
