In this video we shall cover the concepts of load balancing in system design. We shall start with the basics using a practical use case and then move into dns based load balancing followed by L4 L7 based load balancing. This can be pretty useful for all person willing to learn or move in to solution and system design as well as for system design interviews and discussions. After watching this video you should be able to understand and build components and answer some of the basic questions like What is L4 load balancing ? What is L7 load balancing ? What is DNS based load balancing ? What are Round Robin and AnyCast ? Index 0:00 - Intro 0:35 - Agenda 1:02 - Basic Concepts - What and Why 9:00 - Types of Load Balancer 10:15 - DNS Load Balancer Round Robin 14:31 - DNS Load Balancer Anycast 16:20 - OSI Model 18:51 - L4 LB Features 20:20 - L7 Load Balancer 22:48 - Difference between L4 and L7 Load Balancer 23:50 - Where to use what 25:20 - Closing, Thanks

In this Masterclass you will learn how to generate Sequence Diagram using PlantUML which is diagram as a code library, very easily and quickly. PlantUml can create all sorts of activity, sequence, state, class, C4 and a lot of other diagrams. Sequence diagrams which are covered in this video are a major part of software design and and software architecture and provides basic functionality to document and show any flow on a diagram. This video does not require you to have any prior experience and you will learn almost all the necessary action items that you might need for most of your day to day operations. We shall be creating Sequence Diagrams easily with VS Code.

Async Streams is the new feature in C# 8.0 which provides async support for handling streams or IEnumerable data. In this session we cover all the aspects of Async Streams (IAsyncEnumerable) including how to use ConfigureAwait and how to use CancellationToken as well. Cancellation token can be a great way to manage async programming in dotnet core and C# but with Async Streams it can be a bit difficult and at times if not used properly can give errors. We shall be discussing briefly everything about AsyncStreams. IAsyncEnumerable also has options and support for CancellationToken as well as ConfigureAwait. We also cover the the basic concepts and understanding on how and where it can be used Source Code is available at: https://github.com/letsdocoding/dotnet-programming-general/tree/main/3.%20AsyncNewFeatures Watch out other interesting playlists at Interview Preperation: https://www.youtube.com/watch?v=LCv7PDXoxqw&list=PL3TuugVsz1mNEHZAZA9t_i3E7Ofut06Ai Programming Basics / Concepts: https://www.youtube.com/watch?v=LCv7PDXoxqw&list=PL3TuugVsz1mOTM86OLvCN_sJ1x_M6Q2TH Managed Cloud Identities: https://www.youtube.com/watch?v=PM_ny-nWME4&list=PL3TuugVsz1mOC08d7tBqx6Py-dCG9wwd5 Index 0:00 - Intro 02:35 - What are Async Streams - Basic Understanding 07:23 - Synchronous Example 09:42 - Converting to IAsyncEnumerable 10:44 - static async Task Main() 13:00 - Running the code 14:30 - Cancellation Token 14:54 - Cancellation token as parameter 17:10 - Cancellation token using WithCancellation 17:29 - ConfigureAwait 18:19 - Thanks

This video is the first in the series to discuss the benefits of cloud identities using the managed cloud identities, why you should NOT store the identities by yourself and never again do self authentication and authorization with full hands on labs with Azure, AWS and Auth0. This video covers the basics of cloud identities and highlights some of the benefits of cloud based managed identities and risks of authentication when using self hosted application based authentication in the database or other approaches.

Remove all your nested and complex if-else if - else logic with switch expressions. With concise statement, better readability, its one of the major change brought in core programming concepts since school days. in addition to improve better chances at interview with more readable and better understandable code, this also improves overall efficiency and productivity. This video covers briefly the new c# switch expressions introduced in C# 9.0 along with all the changes around the switch that happened from C# 7.3, C# 8.0, C# 9.0. when keyword and conditional attributes were allowed in C# earlier but with C# 9.0 its a totally different game. In this detailed hands-on lab we shall be visiting all the new language features and cover them in detail. Cover this with the power of .net core, this can boost the productivity to next level with all the smart programming and clean code with better readability.
