Layoutit grid is an open-source CSS Grid layout generator. It aids in designing web pages layouts by providing CSS grid code as markup.

* While you can manage a few containers manually using Docker and Windows, apps often make use of five, ten, or even hundreds of containers, which is where orchestrators come in. Orchestrators help you grow containerized apps at scale, providing functionality for:

  • Deploying at scale
  • Workload scheduling
  • Health monitoring
  • Failing over when a node fails
  • Scaling up or down
  • Networking
  • Service discovery
  • Coordinating app upgrades
  • Cluster node affinity

* Open Service Broker for Azure, or OSBA, lets you provision Azure Cloud Services directly from Kubernetes or Cloud Foundry. OSBA in an Open Service Broker API implementation for Azure. The Open Service Broker API is a spec that defines a common language for cloud providers that cloud native applications can use to manage cloud services without lockin.

Application Proxy is a feature of Azure AD that enables users to access on-premises web applications from a remote client. Application Proxy includes both the Application Proxy service which runs in the cloud, and the Application Proxy connector which runs on an on-premises server. Like most Azure AD hybrid agents, the Application Proxy Connector doesn't require you to open inbound connections through your firewall.

Azure Arc enables you to manage, govern, and secure servers across on-premises, multiple cloud, and edge scenarios.

Azure Virtual WAN is a networking service that brings many networking, security, and routing functionalities together to provide a single operational interface. The Virtual WAN architecture is a hub and spoke architecture with scale and performance built in for branches (VPN/SD-WAN devices), users (Azure VPN/OpenVPN/IKEv2 clients), ExpressRoute circuits, and virtual networks.

* Using a templatized process to containerize apps running on servers, the Azure Migrate App Containerization tool makes it easy to containerize, test and migrate your existing applications to Azure Kubernetes Service.  Using the discovered information and inputs from the previous step, the tool generates a suggested Dockerfile that can be used to build the container image for the application.  With the container image built, the tool generates the Kubernetes resource definitions specification file to deploy the apps to your Azure Kubernetes Service cluster. 

* PolyBase enables your SQL Server instance to query data with T-SQL directly from SQL Server, Oracle, Teradata, MongoDB, Hadoop clusters, Cosmos DB without separately installing client connection software. You can also use the generic ODBC connector to connect to additional providers using third-party ODBC drivers. PolyBase allows T-SQL queries to join the data from external sources to relational tables in an instance of SQL Server. A key use case for data virtualization with the PolyBase feature is to allow the data to stay in its original location and format. You can virtualize the external data through the SQL Server instance, so that it can be queried in place like any other table in SQL Server. This process minimizes the need for ETL processes for data movement.

* Deploying an SAP system as a manual process can quickly become costly due to divergence in  resources and configuration, or discrepancies introduced through human error. To reduce this impact, improve consistency, and reduce lead times, Microsoft is approaching the SAP deployment as an opportunity to define the SAP Infrastructure as Code (IaC) and capture the configuration activities as Configuration as Code (CaC). SAP on Azure Deployment Automation Framework is an extensible framework that will modularly address the complexities of running SAP on Azure.

* Azure Orbital is a Ground Station As-a-Service that provides communication and control of your satellite. 

Data transfer from AWS to the internet is charged per service, with rates specific to the originating Region.

  • Data transfer within AWS - between your workload and other AWS services
    • Accessing services within the same AWS Region 
    • Accessing services across AWS Regions
    • Data transfer within different components of your workload within same 
    • Data transfer within different components of your workload  different AWS Regions
  • Data transfer between AWS and on-premises data centers
    • Data transfer over AWS Site-to-Site VPN
    • Data transfer over AWS Direct Connect
Both ingress and egress are charged when that transfer involves Amazon EC2 instances that are placed across Availability Zones in the same region.

* To determine the IO requirements for Azure implementation of an Oracle database, estimate using Oracle Statspack and AWR reports or OS level storage monitoring tools. The main difference between these AWR & Statspack reporting methods is that AWR is automatically collected and provides more information about the database than it's predecessor reporting option of Statspack.

* As Oracle is an IO intensive database for many, it's quite important to size the storage based on the IOPS rate rather than the storage size. For example, if the required IOPS is 5,000, but you only need 200 GB, you might still get the P30 class premium disk even though it comes with more than 200 GB of storage.

* IOPS X IO Size = Throughput

* An opinionated and irreverent article that questions and analyses popular EA frameworks: the Zachman Framework, Federal Enterprise Architecture Framework (FEAF), Department of Defense Architecture Framework (DoDAF) and The Open Group Architecture Framework (TOGAF)

* Google has developed a custom-built System on a Chip (SoC), Tensor, to power Pixel phones. After Apple ( M1), Huawei (Kirin), Samsung (Exynos), now Google has joined the in-house SoC club. 

* Wireless AC (802.11ac) Wave 2 is a networking standard that produces higher wireless speeds on the 5 GHz band. 

Wireless USB Adapter plugs into any USB port to enable Wi-Fi to computers/devices turning them into a wireless online device. Its small size ensures your devices get wireless access without bulky antennas or large dongles. 

* A USB-powered device unlike a USB connected device doesn’t require a separate power source. 

* Your Phone app on Windows 10 PC lets you connect to select Android and Samsung devices. Apps is available on Android devices in select markets running Android 9.0 or greater that have Link to Windows installed. Apps allows you to view phone apps through your PC on a bigger monitor.

* Ada Lovelace was an English mathematician and writer, chiefly known for her work on "the father of computers" Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She is often regarded as the first computer programmer. She was the only child of poet Lord Byron and Lady Byron. Lord Byron expected his child to be a "glorious boy" and was disappointed when Lady Byron gave birth to a girl. Her mother remained bitter and promoted Ada's interest in mathematics and logic in an effort to prevent her from developing her father's perceived insanity. Despite this, Ada remained interested in him, naming her two sons Byron and Gordon. Upon her eventual death, she was buried next to him at her request. The computer language Ada, created on behalf of the United States Department of Defense, was named after Lovelace.
