Kubernetes resource that ensures a single pod per node is the DaemonSet. A DaemonSet ensures that all (or some) nodes run a copy of a pod. When a new node is added to the cluster, the DaemonSet automatically schedules the defined pod on that node. If a node is removed from the cluster, the DaemonSet ensures that the corresponding pod is terminated.
By following this approach, we successfully migrated the application to a microservices architecture with minimal downtime and negligible impact on data integrity. The experience taught me the importance of careful planning, incremental changes, and continuous testing in tackling complex technical challenges."
Azure SQL Database provides industry leading high availability guarantee of at least 99.99% to support mission critical and a wide variety of applications that need to be always available. Azure SQL Database also has capability to have turn key business continuity solution that lets you perform quick disaster recovery in the event of a regional outage. This article contains valuable information to review in advance of application deployment.
Configuring an IoT Edge module on a device involves several steps to ensure proper deployment and functionality. Below is a general guide that outlines the steps for configuring an IoT Edge module:
Kubernetes is a portable, extensible, open source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available.
IoT Edge can be installed on Kubernetes by using KubeVirt technology. KubeVirt is an open source, Cloud Native Computing Foundation (CNCF) project that offers a Kubernetes virtualization API and runtime to define and manage virtual machines.
Multicloud computing refers to the use of multiple cloud computing services from more than one cloud provider (including private and public clouds), in a heterogeneous environment. A multicloud strategy provides greater flexibility, and mitigates risk. Choose services from different cloud providers that are best suited for a specific task, or take advantage of services offered by a particular cloud provider in a specific location.
You can use X.509 certificates to authenticate devices to your IoT hub. For production environments, we recommend that you purchase an X.509 CA certificate from a professional certificate services vendor. You can then issue certificates within your organization from an internal, self-managed certificate authority (CA) chained to the purchased CA certificate as part of a comprehensive public key infrastructure (PKI) strategy. For more information about getting an X.509 CA certificate from a professional certificate services vendor, see the Get an X.509 CA certificate section of Authenticate devices using X.509 CA certificates.
