CertificateOfCompletion_Learning-RabbitMQ

Course Details

RabbitMQ is one of the most popular open-source message brokers in use today. This lightweight software can help companies that have adopted a microservices model stitch together and enable communication between their services. This course demonstrates how to properly install and work with RabbitMQ. After delving into the fundamental concepts behind message-based systems and the AMQP message protocol, it explains why you might want to use RabbitMQ, as well as how to install it. It then showcases how to implement the tool, covering both basic usage, such as how to publish to and consume from a RabbitMQ exchange, as well as more advanced topics like setting up and using authentication in RabbitMQ.

Learning Objectives

How message-based systems are used
The AMQP protocol
Exchange type use cases
Publishing to RabbitMQ
Consuming from RabbitMQ
Filtering messages with direct and topic exchanges
Setting up and using authentication
Authorizing and blocking application actions
Tracking message contents for troubleshooting

Course Details

Threading is a powerful tool for developers, and having a solid grasp of how it works is key to creating high-performing applications. Threading—or multithreading—can help you create scalable applications that are more responsive to user input. This course teaches how to write applications that perform multiple tasks at the same time. It covers basic threading concepts, including context switching and exception handling. It also discusses how to synchronize code, use a mutex and a semaphore, and more.

Learning Objectives

Debugging threads
Threads vs. processes
Using a thread pool
Tasks vs. threads
Tasks with IO
Using monitors and locks
Nested locks

CertificateOfCompletion_Azure-Security-Best-Practices-AZ204

With Azure Services the time to market for application development is faster than ever before. At the same time, any security issues we might face will have a wider impact than ever before. It’s a bad day when you discover that the security credentials of your application have leaked. Azure offers a rich set of tools to keep your app secure and protect your credentials. The tools take care of all the heavy lifting, but they can only do that if you understand how they work. This course explores the baseline Azure security controls and discusses Azure application security best practices. When you design your systems from the beginning with these features in mind you can easily design, implement, and monitor the security of your apps throughout their development lifecycle.

Azure Event Grid

by robin5

CertificateOfCompletion_Azure-Event-Grid

As we build more and more involved cloud-based applications, there is inevitably the need for the various parts of our solutions to talk to each other, not to mention a lot of long running tasks in the cloud are asynchronous in nature. So how do we know when one task finishes and the other needs to be informed? Classically, there has been a lot of polling involved. Are you done? Are you done? Are you done? And this causes the bill to go up, up and up because something is doing this polling and you’re paying for that something. Azure Event Grid, a fully managed event crowding service that works using a pub/sub model solves exactly this problem. And now because you’re using a standard spaced eventing model, a number of possibilities open up. Suddenly, all of your services can talk with each other securely and effectively.

Azure Service Bus

by robin5

CertificateOfCompletion_Azure-Service-Bus

Azure Service Bus allows applications to talk to each other. The applications may be written in any major platform. They’re able to talk to each other asynchronously via queues, topics, and subscriptions. While queues allow you to build First In, First Out messaging paradigms, topics and subscriptions open further architectural patterns. This course explains what Service Bus is, and what its major components are. Then using code demonstrations, it shows how to take advantage of Azure Service Bus queues, topics, and subscriptions.
