Different cloud providers (such as AWS or Azure) offer computing capacities for customers to deploy their cloud-based applications. Using these services also directly affects the software architecture used to build these applications. Critical aspects to consider include:

• Scalability
• Compelxity
• Servicability

The goal of this seminar topic should be to describe the design concepts and principles employed for cloud-based applications. A special focus should be placed on software architectures that use microservices, analyzing their benefits while also describing their drawbacks.

Efficient use of the available computing resources is an important to achieve the best possible performance of a computing platform. A key component in such architectures is the operating system, which provides an interface for other software and application to run and use the hardware.

As many applications can run concurrently and therefor compete for the available compute resources, the operating system is responsible for providing the desired scheduling. While this has been historically the job of the kernel, numerous approaches exist to move some functionality of task and thread scheduling into user space.

This seminar topic should analyze the different approaches for userspace scheduling, highlighting their differences by looking at their implementation, performance, and motivation.
