Case You have a Linux-based KVM installation and you need to deploy Cloudstack latest version to control your KVM hypervisor and virtual machines. This article provides high-level guidance on how to deploy Cloudstack on Ubuntu Linux. This article is being updated to include more detailed steps for configuring all aspects of Cloudstack deployment on Ubuntu Linux. Bear in mind that this post assumes 14.6.1.0 version of Cloudstack. You should always consult the latest documentation from the official Cloudstack website. See the refences section of this post for details. Solution The Cloudstack (CS) management server can be installed on any supported Linux distribution, including the following: - Ubuntu 18.04 LTS, 20.04 LTS - CentOS versions 7, 8 (note: CentOS 8 will EOL in Dec 2021) - Rocky Linux 8 - RHEL versions 7, 8 - openSUSE Leap 15 - SUSE Linux Enterprise Server 15 (not tested, but expected to work same as with openSUSE 15) The CS management server can be a physical server or a virtu...

gRPC announcement Microsoft announced today that gRPC is now available and supported on Azure App Service for Linux workloads. This was made possible by recent platform upgrades to the HTTP reverse proxy layer to leverage YARP and Kestrel . This is an important announcement as it removes the native support limitation in Azure App Service which prevented the migration and usage of gRPC-enabled applications in Azure App Service. In such cases, running the Azure App Service migration assessment tools would report incompatibility errors, leaving you with the pain of having to decide upon an alternative design option for your net.tcp, wcf or gRPC applications. gRPC utilizes the remote procedure call (RPC) framework to streamline messages between clients and servers over the HTTP/2 protocol. Using gRPC protocol over HTTP/2 enables the use of features like multiplexing to send multiple parallel requests over the same connection. gRPC is currently available for use with .NET Core 3.1 and .N...

Case You need to install the KVM hypervisor in Ubuntu Linux. For the purpose of this demo I will be deploying KVM in Ubuntu Linux LTS server, as shown below. However you can follow the same procedure on any Linux platform, making any adjustments related to the package management system used by your distribution (e.g. deb vs rpm). This article offers step-by-step instructions on how to install KVM in Ubuntu Linux. Solution First check if your Ubuntu server or desktop installation supports virtualization by running the below command. You need to get a result which is greater than 0, to ensure that your system supports virtualization. egrep -c '(vmx|svm)' /proc/cpuinfo Run the following command to ensure that kvm can be supported and installed on your machine. If the kvm-ok command is not available it should be installed as part of the cpu-checker deb package. You are now ready to install the KVM-related packages to enable KVM virtualization in your Ubuntu system. Run the command ...

Introduction The current post attempts to present an overview of the Azure database services, as of late May 2022. Azure database services mainly cover the conventional database administration side of things (with SQL and NoSQL databases) but can conceptually expand to cover a full range of Analytics and Data Engineering and Analysis services (for example Azure Data Factory and Azure Synapse Analytics). This broader view of data-related services essentially constitutes the Azure Data Platform . Given the dynamic nature of public clouds, this list will most likely change soon in the near future but nevertheless acts as a general point of reference when discussing Azure database services. You find an overview of all Azure service categories at https://stefanos.cloud/blog/azure-service-categories/ . Database services Azure allows you to support rapid growth and innovate faster with secure, enterprise-grade, and fully managed database services. Azure Cache for Redis Accelerate apps with h...
