This guide outlines the installation and configuration of a secure SFTP server with OpenSSH on Rocky Linux 9. It covers installing OpenSSH, configuring sshd_config for SFTP with chroot and group restrictions, creating a user group and user accounts, setting permissions, and confirming operation through restricted directory access and encrypted communication.
Attempting to renew self-signed certificates with vSphere 7.0 Certificate Manager, the author faced issues renewing certain certificates such as the STS, encipherment, and ESXi certificates. They followed specific VMware articles and utilized tools like vCert to address the problems. After troubleshooting and manual interventions, including removing expired VMCA certificates and renewing the encipherment certificate, all certificates showed a valid status except for the backup entries.
The post outlines a Jenkins job that automates the deletion of surplus NetApp ONTAP configuration backups on a remote SFTP server, using a bash script to retain only the three most recent files per unique hostname. The Jenkins project is scheduled daily and executes the cleanup script remotely. The source code is available on GitHub.
This post demonstrates automating the NetApp ONTAP upgrade process using Ansible for efficient management of numerous clusters. It outlines a playbook that includes pre- and post-upgrade tasks to display ONTAP versions and executes the software update, with the option to only download images. The complete code and a GitHub link are provided.
This post explains using Ansible and REST to report on server certificates across NetApp ONTAP clusters. It details gathering certificate data, transforming it to CSV, and emailing the report. Ansible tasks include extracting specific certificate fields, organizing them into a CSV file, and distributing the report via email using a Jenkins-scheduled playbook. The process serves to manage and renew certificates effectively.
Artificial Intelligence (AI) and Machine Learning (ML) are revolutionizing business operations. Microsoft's Azure offers a robust AI and ML portfolio, including Azure Applied AI Services, Cognitive Services, Machine Learning, and AI Infrastructure, enabling the creation of intelligent applications. Azure's integration with OpenAI distinguishes it from competitors like AWS and GCP, by providing advanced AI algorithms for businesses to enhance automation, decision-making, and customer experiences, reinforcing its edge as a cloud provider.
NetApp clusters enhance performance and availability, with Storage Virtual Machines (SVMs) providing services to clients. Export policies and RBAC ensure secure access, critical for compliance with PCI DSS, which safeguards credit card data. For payments companies, dedicated SVMs can meet PCI DSS requirements. NetApp's CLI configures access controls, with separate domains for PCI DSS environments and non-PCI users, maintaining stringent access restrictions and fulfilling audit mandates.
As businesses adapt to post-COVID realities, they face rising costs and service limitations of public cloud services. Although these services reduce hardware investments and offer scalability, prices are climbing as demand increases, and currency weakness affects costs. Mitigation strategies involve cost optimization techniques like auto-scaling, third-party monitoring, and disaster recovery plans. Consulting and engineering for cloud-agnostic approaches reduce risks of outages and capacity issues. Despite these challenges, the benefits of public cloud, like security and ongoing provider investments, maintain its appeal for businesses.
Ephemeral OS disks in Azure, suited for stateless VMs, boost boot speed and performance by utilizing local storage, reducing costs. These temporary, low-latency disks are managed by Azure and lost upon VM restart or deletion; hence they're unsuitable for stateful VMs. Creating a VM and reimaging discards all changes, reverting to a pristine state.
Azure Kubernetes Service (AKS) offers scalable, reliable cloud computing with simplified management and integration with Azure services. It stands out as cost-effective compared to AWS's EKS and GCP's GKE, providing the latest Kubernetes updates and a pay-as-you-go model. To further reduce costs, services like Spot by NetApp and Ocean optimize cloud expenses, making AKS a robust choice for containerized applications.
