    Totally agree that understanding internal aspects of AJAX is a key in solving performance problems. What makes UpdatePanel slow? While AJAX is considered by many a client-side technology, the ASP.NET AJAX request, just like web form request, submits to the server a Viewstate for the entire page and requires full page execution. The response downloads bulky HTML including ViewState. Multiple ScriptResource.axd requests also slowdown initial page load.

    AJAX pages would be much faster if UpdatePanel could download only data-related traffic without Viewstate and generate HTML on the client, or even better, could be entirely executed on the client without server roundtrips. It would be ideal if post request could be compressed, JavaScript resources download from the server could be avoided, and all of that almost without coding.

    To implement this approach we developed ASP.NET software accelerator, Web Stimulus.

Maven Crash Course - Learn Power Query, Power Pivot & DAX in 15 Minutes

Image
In the Maven Crash Course " Learn Power Query, Power Pivot & DAX in 15 Minutes ", Chris Dutton walks through a hypothetical business case while showcasing the power of modern Excel tools like Power Query, Power Pivot and DAX. Power Query is used to extract, transform, and load data from external sources like SQL databases, PDF and CSV files. A relational model is created to join the tables without writing a single formula. Exploratory analysis is done using Power Pivot and Data Analysis Expressions (DAX). Data Analysis Expressions is the language that we can use to define new calculated columns and measures to enhance our Data Model instead of the traditional cell formulas that we'd typically use if our data was stored in worksheets. Pivot Charts and slicers are used to design a simple interactive report that the sales managers can use to analyze revenue trends and product performance.

Gartner Magic Quadrant for Strategic Cloud Platform Services

Gartner defines strategic cloud platform services (SCPS) as standardized, automated, public cloud offerings integrating infrastructure services (e.g., computing, network and storage), platform services (e.g., application, data and value-added services such as AI/ML) and transformation services (resources to help customers adopt cloud-oriented IT delivery models). Image - Gartner Insights I found interesting from the Gartner Magic Quadrant for Strategic Cloud Platform Services report: The eight SCPS providers & global hyperscalers featured in this Magic Quadrant control over 97% of the total CIPS market. While AWS has maintained profitability and a leading global infrastructure as a service (IaaS) and platform as a service (PaaS) market share of over 42%, its growth rate relative to its key competitors slowed in 2023. Azure public cloud market share is 26%. GCP's overall market share stands at 11.5%. Oracle's strategy of positioning OCI as the top cloud for Oracle software i
