Concurrency and Parallelism
Efficiency at every level of your tech stack.
As traffic grows and requirements increase, simple sequential processes quickly reach their limits. This is where concurrency and parallelism come into play to make your applications more powerful and scalable. At DevCraft Academy, we teach you the practical skills to successfully implement these concepts in your projects – from processing multiple user requests simultaneously to optimizing pipelines and tests.
Concurrency and parallelism are essential for keeping modern applications performant. Those who master these techniques can not only increase throughput but also minimize bottlenecks and ensure system stability.
Why are concurrency and parallelism so important?
Modern applications often need to handle multiple tasks simultaneously. Whether it's processing user requests concurrently, parallel database queries, or running background processes. Understanding concurrency and parallelism allows you to significantly improve your application's performance and achieve better scalability. Knowledge of these concepts often determines whether an application remains stable under load or starts to struggle.
What you'll learn with us
At DevCraft Academy, we give you comprehensive insight into the world of concurrency and parallelism. You'll learn the underlying concepts, but most importantly, how to apply them effectively in real projects to make your applications stable and performant.
Our key topics at a glance:
Horizontal Scaling: The key to high-growth applications. Multiple instances across different servers distribute the load, allowing more users to be served simultaneously.
Multiple Database Connections & Parallel Queries: Parallel database operations are essential for maintaining high performance in complex applications. We show you how to efficiently manage multiple connections and execute queries in parallel.
Concurrent Processing of User Requests: Applications must serve more and more users simultaneously. With the right techniques, you can optimally distribute the load so that all requests are answered quickly and reliably.
Concurrency in JavaScript and Promises: In JavaScript, asynchronous programming is made possible through Promises, Async/Await, and Events. These concepts make it easier to manage concurrent tasks without losing oversight.
Event Loop and Events: The JavaScript event loop manages the concurrent processing of tasks. Understanding it allows you to identify bottlenecks and increase efficiency.
Processes and Threads: Operating systems use processes and threads to execute parallel tasks. Through skillful thread management, you can handle demanding tasks simultaneously.
Parallel Test Execution & Pipelines: In continuous integration pipelines, tests and builds can be executed in parallel. This saves time and accelerates the development cycle.
Web Workers: In the browser, Web Workers allow you to offload computationally intensive tasks to separate threads. This keeps the user interface fluid while processes run in the background.
Common Problems with Parallel Processing: Race conditions, deadlocks, and livelocks are challenges that can occur with parallel processes. Through appropriate techniques and synchronization mechanisms, these pitfalls can be avoided.
Benefits of Sequential and Parallel Processing: Not every task benefits from parallelism. Strategic use of sequential processing can be more efficient in some cases.
Background Workers: Tasks that don't need to be completed immediately can be offloaded with background workers. This improves overall performance and ensures that main processes continue undisturbed.
Why DevCraft Academy?
Concurrency and parallelism are highly complex topics, but don't worry – with us, you'll learn the relevant concepts step by step and always hands-on. We don't just show you the theory, but place special emphasis on enabling you to apply what you've learned directly in your projects. Our goal is to prepare you for the challenges of modern software development – from the event loop in JavaScript to parallel test execution and cloud scaling.
Concurrency and parallelism are the keys to scalable, performant applications. At DevCraft Academy, you'll learn how to strategically apply these techniques to make your software more efficient and handle multiple user requests simultaneously.
