Tech Tips, Tricks & Trivia

This Week I Learned - *  RBAC is an authorization system built on Azure Resource Manager that provides fine-grained access management of resources in Azure. *  Hub and spoke is a networking model for more efficient management of common communication or security requirements. It helps avoid Azure subscription limitations, save costs by centralizing services that can be shared by multiple workloads and aids separation of concerns through deployment of individual workloads between central IT teams and workload teams. *  The hub is a virtual network (VNet) in Azure that acts as a central point of connectivity to your on-premises network. The spokes are VNets that peer with the hub, and can be used to isolate workloads. *  A hub-spoke topology can also be used without a gateway, if you don't need connectivity with your on-premises network. *  As a first step toward migrating a datacenter to the cloud, the first services that need to be shared are iden...

This Week I Learned - *  Application security groups enable you to configure network security as a natural extension of an application's structure, allowing you to group virtual machines and define network security policies based on those groups. You can reuse your security policy at scale without manual maintenance of explicit IP addresses. *  The icons we see on apps & websites are called by different names . The vertical stack burger icon signifying navigation drawers provide access to destinations and app functionality, such as switching accounts. The 3 dots ellipsis icon is called kebab menu by some and overflow menu by Google which uses it to represent App & placed on the right side of an app. * Now, not every project needs a framework and not every page of a single-page-application needs to load a framework. In Netflix’s case, "removing React, several libraries and the corresponding app code from the client-side reduced the total amount of JavaScript by ...

This Week I Learned - * A proximity placement group is a logical grouping used to make sure that Azure compute resources are physically located close to each other. Proximity placement groups are useful for workloads where low latency is a requirement. A proximity placement group is a new resource type in Azure. You need to create one before using it with other resources. Once created, it could be used with virtual machines, availability sets, or virtual machine scale sets. *  CPUs usually have between 2 and 8 cores. GPUs usually have at least a few hundred cores, and often more than 1,000 cores. GPUs are built for extreme parallelism . discovered via @addyosmani 's tweet *  LinkedIn Sales Navigator , is meant for sales professionals to discover leads, understand key insights, and engage with personalized outreach. *  Dux-Soup is a lead generation tool for LinkedIn. It is a Google Chrome browser plug-in which works as a virtual assis...
