K8s/Kubernetes: AWS vs. GCP vs. Azure
Kubernetes (“K8s”) won the battle of container orchestration tools. Now AWS, Azure, and Google Cloud each offer a managed Kubernetes version. How do they compare?
Bridging Gaps: The Importance of DevOps Communication
DevOps is an oft-misunderstood buzzword, seen as a trendy must-have in the form of technologies, tools, and staff to acquire. But it’s much more, yet much simpler, than that.
Do the Math: Scaling Microservices Applications With Orchestrators
Automatically scaling container deployments in a microservices-based app architecture is downright luxurious…once it’s set up. But what’s the best way to tune an app’s orchestration parameters?
A Better Approach to Google Cloud Continuous Deployment
Continuous deployment is the practice of automatically deploying new code to production. Most continuous deployment systems validate that the code to be deployed with tests, and then build and deploy if everything looks good. However, there’s a better way.
In this article, Toptal Freelance DevOps Engineer Antoine Reversat builds an event-driven continuous deployment pipeline that builds first and then runs tests on our final deployment artifact before deploying. This makes test results more reliable, and the CD pipeline easily extendable.
Zero Downtime Jenkins Continuous Deployment with Terraform on AWS
When your app’s next iteration is ready to deploy, you have two choices: either stop the entire application and deploy the new version manually every time or build an automated zero downtime CI/CD deployment pipeline once.
In this article, Toptal Freelance DevOps Engineer Gaurav Kohli demonstrates the latter using the Jenkins-powered continuous deployment pipeline of a three-tier web application built in Node.js, deployed on AWS Cloud, and using Terraform as an infrastructure orchestrator.
Terraform AWS Cloud: Sane Infrastructure Management
Writing an application is only part of the story. In order for it to be of value, it needs deploying somewhere it can scale; it has to run with high availability, have backups, and so on. Deployment and infrastructure management isn’t a simple process. And Terraform does nothing to hide the complexity. However, it does make your infrastructure declarative and reproducible, like your code.
In this article, Toptal Freelance DevOps Engineer Radosław Szalski teaches us what Terraform is, how its components work, and how to configure an entire AWS Cloud solution in minutes using its configuration language.
What Is Kubernetes? A Guide to Containerization and Deployment
As we start transitioning to microservice-based architectures, a question arises: What should I choose to make my service stable as well as easy to manage and deploy?
The short answer is: Use Docker!
In this article, Toptal Freelance DevOps Engineer Dmitriy Kononov gives you the long answer by introducing you to containers, explaining Kubernetes, and teaching you how to containerize and deploy an app to a Kubernetes cluster using CircleCI
How to Build an Effective Initial Deployment Pipeline
Do you run deployment scripts from your development machine, or find yourself referring to deployments by the day of the week they were deployed, instead of using version numbers? It’s time for a better solution.
In this article, Freelance Ruby Engineer and automation enthusiast Amin Shah Gilani walks you through his perfect deployment pipeline to use at the beginning of your project. With this CI/CD configuration, every push is tested, the master branch is deployed to staging servers with a fresh database dump from the production server, and versioned tags are deployed to production with backups and migrations running automatically.

Risk vs. Reward: A Guide to Understanding Software Containers
Software delivery has come a long way. And, somewhere between the transition from physical media to software containers, we have changed the way we try to manage them.
In this article, Toptal Freelance Software Engineer Jonathan Bethune explores how software containers have motivated us to treat servers as more dispensable, and the risks and rewards involved.
