Imagine you have the following requirement: some pods need to be placed on specific nodes dedicated to compute intensive, memory intensive, and storage intensive workloads. How do you ensure these pods are scheduled correctly and not placed on other nodes? At the same time, how do you ensure that no other pods are placed on these optimized nodes? My latest article, “Kubernetes Pod Scheduling Explained: Taints, Tolerations, and Node Affinity”, tackles this exact scenario. https://lnkd.in/d3X7w2Bi #kubernetes #devops #cloud

One of my beefs with terraform is it’s trying so hard to be flat. Some of us want very dynamic scripts. But when you create a k8s cluster, form the kubexonfig file, then need to use the kubexonfig file to load in the rest of the parts like ingress, having a depends_on would be nice for providers. I did cheat a little and abuse the variable system to force the provider to wait, but then you run into what about a workspace that will have kubernetes set to false and get a zero count for your k8s module? Then it gets angry because the module output isn’t there. I still like Chef. Chef let me do what I want when I want. Just was bad on creating the underlying infrastructure but great at configuring it once it was up. *shrug* #terraform #kubernetes #k8s #eks #automation #burgerkingmodel

Terraform's Import block functionality will help give a lot of companies the ability to bring their existing infrastructure under a unified code base. Now with the ability to use for_each inside their import block this video shows a cool way to utilize that feature to build on top of your existing pipelines without having to re-engineer anything.

This week's issue explores the role of DevOps in AI/ML, future trends in distributed systems, and secure multi-cloud authentication. Also covered are Kubernetes security with AppArmor and a new Google data center. Featured tools include RunCVM for secure container isolation in VMs, Tools for automated structured logging for applications, and tooling out of grafana labs for load testing.

AWS Lambda is an almost instinctual choice when it comes to building on AWS Cloud (and why not? It's awesome!). But are Lambda functions - and the custom libraries and code that comes with them - always the right choice? Particularly for gluing components together? I spend some time exploring the potential of working with native AWS services to produce an event-driven solution with no Lambda or custom code in sight. #aws #eventbridge #software #architecture #serverless

Containerization is a powerful tool for managing workloads. However, not all workloads are suitable for containerization. In this tech talk I cover out how to handle virtualized workloads that don’t make sense to containerize while leveraging the robust self-healing capabilities of Kubernetes.

🎉 Celebrating a Decade of Kubernetes: A Journey of Innovation and Community 🎉 Kubernetes is celebrating its 10th anniversary! What began as a Google project has evolved into a cornerstone of the tech industry, transforming how we manage and deploy applications. Key milestones: 2014: Open-sourced by Google 2015: Kubernetes 1.0 release and CNCF formation 2016: Rapid adoption as the top container orchestration platform Kubernetes wouldn't be where it is today without its vibrant and dedicated community. With over 88,000 contributors and a global user base of over 7 million developers, Kubernetes exemplifies collaboration and innovation. To commemorate this milestone, the CNCF hosted a logo design contest, and we now have a special 10th Anniversary Logo designed by Cristher Castro and her team at Cuemby.

🔒 How do you manage secrets in your Kubernetes environment? 🤔 Kubernetes is challenging when it comes to secret management, that’s a fact. How do you ensure your secrets are secure? Do you use a centralized or decentralized approach? Where do you keep your secrets? One effective tool is Sealed Secrets by Bitnami. This tool offers a secure way to encrypt secrets before they reach your cluster, ensuring that sensitive data is protected at all times and can be safely stored in a Git repository. #devops #kubernetes

Cost-Effective VM Migration with VM Import/Export on AWS Migrate your VMs to AWS without breaking the bank! VM Import/Export is a cost-effective solution. Pay-As-You-Go Model:You only pay for the AWS resources you utilize during the import and export processes, including S3 buckets, EBS volumes, and running EC2 instances. No Additional Fees:There are no upfront charges or hidden costs associated with using VM Import/Export itself. More about this topic on AWS official site. And if you want to find out more about cloud cost optimization visit https://umbrelly.cloud/!

Leverage vSAN for persistent volumes in your #Kubernetes deployments!  This YouTube video  Learn how to manage storage policies and overcome operational challenges for a seamless #cloudnative experience. CSI automates the storage creation process, eliminating the need for manual intervention. It consists of three different classes: block volumes, file volumes, and storage policies. Block volumes are accessible by only one container, while file volumes are commonly mapped in the storage class. Storage policies are used to define data storage and resiliency specifications. CSI allows mapping these classes together, enabling you to call a PBM policy from within the YAML configuration during container creation. Overall, CSI automates storage provisioning and management for containerized applications. https://lnkd.in/eHfDFK-c  #VMware #vSphere #vSANCSI #KubernetesStorage #DataManagement #CloudStorage #DevOps #ITInfrastructure #Containerization #DigitalTransformation #broadcom #sds #kubernetes #tanzu #iaas

Modern Software Architecture is a Joke, Exhibit number 122454676: Move joins into the application layer Complex joins are another area where extensive database resources can be required. Rather than joining data in the database, move as much of that joining logic as you can into the application layer. By refactoring your code in this manner, you can reduce the load on your database significantly, while increasing your scalability. https://lnkd.in/dABS99kV
