Microsoft Azure cost management in cloud-based software development

Software development, testing and R&D activities very often require considerable cloud resources. At the same time, these are dynamic environments which can lead to ballooning cloud costs. Public clouds such as AWS, GCP or Microsoft Azure have native mechanisms to manage and optimize spend, but they can’t prevent you from incurring unwanted and uncontrolled costs. This led us to create our own cloud cost optimization solution. In this, the final part of our three-part series, we will show you how to build an Azure cost management solution.

How to optimize GCP costs in cloud-based software development

Scalability, availability and high availability—these are the advantages that make public clouds a must have in modern software development. But they can cost you dearly if you don’t manage your cost spending carefully. In the second part of our three-part series on cloud cost optimization, we will show you how to get the GCP bill under control and avoid unexpected cloud costs. Following up on our initial blog about AWS, we’ll now turn to building a cost management solution for the second public cloud: Google Cloud Platform (GCP).

Tungsten Fabric as a Kubernetes CNI plugin

CNI (Container Networking Interface) is an interface between container runtime and network implementation. It allows different projects, like Tungsten Fabric, to provide their implementation of the CNI plugins and use them to manage networking in a Kubernetes cluster. In this blog post, you will learn how to use Tungsten Fabric as a Kubernetes CNI plugin to ensure network connectivity between containers and bare metals. You will also see an example of a nested deployment of a Kubernetes cluster into OpenStack VM with a TF CNI plugin.

AWS cost optimization — keeping cloud-based software development costs under control

Public clouds are now indispensable in modern software development. They offer flexibility, scalability and high availability. At the same time, cloud cost management can be tricky, and generate unwanted spend that will be a considerable burden for the overall budget of your software project. In our three-part series on cloud cost management, you will read how to keep costs under control in the three most popular public clouds: AWS, GCP and Azure. In this first installment, we will present our approach to AWS cost optimization.

How to configure VNFs using a Virtual Network Function Descriptor

Virtual Network Functions (VNFs) are software network elements like routers, firewalls or load balancers that replace networking hardware. Network services are performed by dedicated software that runs on Virtual Machines (VMs) managed by Virtual Infrastructure Managers (VIMs). In this blog post, we describe how to configure VNFs using a Virtual Network Function Descriptor (VNFD) together with a Network Service Descriptor (NSD) and the Open Source MANO platform. Additionally, we will present an initial configuration of a new Virtual Machine (VM) instance using cloud-init.

Managing data center physical infrastructure with Tungsten Fabric

A data center’s physical infrastructure can consist of multiple devices including switches and routers. Managing them can be a time-consuming and error-riddled process. Adding an SDN solution to your legacy data center network makes the entire problem even more complex. Tungsten Fabric, an open-source SDN controller, may be the answer. Read on to know more. Modern data centers are built as flat two/three layers of deeply interconnected devices known as a fabric. This leaf-spine architecture is robust and easy to scale out by adding new devices instead of replacing older devices with more powerful ones.

Deploying a Kubernetes operator in OpenShift 4.x platform

Contrail-operator is a recently released open-source Kubernetes operator that implements Tungsten Fabricas a custom resource. Tungsten Fabric is an open-source Kubernetes-compatible, network virtualization solution for providing connectivity and security for virtual, containerized or bare-metal workloads. An operator needed to be adjusted to the OpenShift 4.x platform, which introduced numerous changes to its architecture compared with previous versions. In this blog post, you’ll read about three interesting use cases and their solutions.

Tungsten Fabric architecture — an overview

SDN or Software-Defined Networking is an approach to networking that enables the programmatic and dynamic control of a network. It is considered the next step in the evolution of network architecture. To implement this approach effectively, you will need a mature SDN Controller such as Tungsten Fabric. Read our blog post to get a comprehensive overview of Tungsten Fabric architecture. Tungsten Fabric (previously OpenContrail) is an open-source SDN controller that provides connectivity and security for virtual, containerized or bare-metal workloads.

The modern, interoperable DC — Part 3: Seamless and secure connectivity for edge computing and hybrid clouds (video)

In the third part of our “Modern DC” webinar series we focus on connectivity with resources located beyond the local data center, somewhere in the Internet. This includes extending Layer 2 and Layer 3 tunnels to public clouds (such as AWS, Azure and GCP), branch offices, Edge Computing servers and IoT devices based on single-board computers.

How to create a custom resource with Kubernetes Operator

While developing projects on the Kubernetes platform I came across an interesting problem. I had quite a few scripts that ran in containers and needed to be triggered only once on every node in my Kubernetes cluster. This could not be solved using default Kubernetes resources such as DaemonSet and Job. So I decided to write my own resource using Kubernetes Operator Framework. How I went about it is the subject of this blog post. When I confronted this problem, my first thought was to use a DaemonSet resource that utilizes initContainers and then starts a dummy busybox container running `tail -f /dev/null` or another command that does nothing.
