Cloud computing usually starts with running a private cloud solution on premises before venturing onto the public cloud. Of course, the cloud is not a single uniform being. It may come from different providers, Amazon Web Services, Google Cloud Platform, and Microsoft Azure being the biggest players here. Or it may come with different visibility and hosting, that is, public (resides with the provider), private (self-hosted), or hybrid (which uses a bit of both). And the cloud can use different tools and APIs for management as well. 148. Future of DevOps: DevSecOps, AIOps and something else? DevOps have become a popular term in the software industry since 2009. The primary reasons behind this increasing popularity are the high-speed and less-cost of development. DevOps were born to meet the increased software industry velocity. In comparison to DevOps, traditional Ops are 41% more time-consuming. 149. Kubernetes Explained Simply: #3 What Do I Have Permissions For? Stretching as far back as version 1.8 (in September of 2017), Kubernetes has supported a fine-grained access control mechanism called RBAC.

Kubernetes Explained Simply: Label it to Enable it [Part 6] The building block of almost all Kubernetes deployments is the pod – one or more containers sharing a network stack. Pods are where the magic happens, where we get our logs, and where we spend most of our time troubleshooting outages and malfunctions. 158. 3 Types of Security Policies You Can Use with Your Kubernetes Pods On August 20, 2020, a provider of access management tools released an advisory detailing several misconfiguration issues that affected the kubelet. This feature of Kubernetes functions as the primary “node agent” running on each node. In order to support this functionality, the kubelet maintains full control over a pod running in a node. 159.

Managing Microservices with Service Mesh: A Control Plane for your Application Applications built on monolithic/ 3-tier/ n-tier architecture often fail to meet the market demands in terms of scaling and performance. This is generally attributed towards the inflexible nature of these architectures, where code base becomes unmanageable due to various reasons - like addition of new features, identifying dependencies, and side effects that could crop up due to scaling, etc. In these environments, adopting new technologies and making changes take a long time. The bottom line is that they are less agile and ancient. 169. SQL Server container in Azure Kubernetes Services (AKS) So recently I got involved with an ASP.NET project which was build over 10 years ago and over the years Developers and Change Requests came and went. And over the period the Application became quite cumbersome and quite hard to understand and manage, the Application became quite large in terms of functionality, codebase and data. 170. Docker: Beginner's Guide If you've been into software or web development for any amount of time, chances are that you at least heard of Docker.

In other words, it allows you to control several remote machines in an automated fashion from a location. 179. How to Use the Scientific Method to Debug Containerized Applications Ah yes—“It works fine on my machine!” Perhaps the most famous saying in our industry. Even with the advent of containers that provide consistent environments across the SDLC, we still hear developers fall back to this claim when a defect is found. But in the end, if the code doesn't work in test or production, it doesn't work—even if it works locally. So as a developer, being able to deep dive into your containerized application to fix the problem—regardless of the environment—is a critical skill we must all learn. 180.
