Networks of Modern Data Centres with CLOS Architecture

In recent years, there has been a rapid increase in the use of applications and services accessible primarily through the public cloud. Similarly, interest in service availability within individual organisations hosted in private or hybrid clouds is growing. This includes the use of advanced technologies such as virtual environments, automation and monitoring tools that enable efficient management and optimisation of resources.

Problem

In recent years, there has been a rapid increase in the use of applications and services accessible primarily through the public cloud. Similarly, interest in service availability within individual organisations hosted in private or hybrid clouds is growing. This trend brings numerous advantages such as increased agility, scalability, elasticity and access to data and services from anywhere and at any time.

However, it also requires appropriate and robust data centre infrastructure that can ensure seamless operation and security of these services. The diploma thesis is dedicated to describing modern concepts, individual building blocks and the architecture of modern data centre networks. In the first part, I focus on contemporary trends and the impact of cloud computing on the development of data centre network architecture and a historical overview of various architectural concepts.

This is followed by a description of suitable protocols and technologies for ensuring efficient operation of cloud services, which requires modern data centre architecture such as CLOS architecture. This architecture enables high performance, reliability and scalability of networks, which is crucial for supporting large workloads and rapidly changing user service requirements. Furthermore, it enables straightforward network management and improved security, which is essential for data protection and ensuring compliance with various standards and regulations.

The establishment and maintenance of modern network infrastructure in data centres are increasingly important.

Solution and Method

This includes the use of advanced technologies such as virtual environments, automation and monitoring tools that enable efficient management and optimisation of resources. This ensures reliability, security and high availability of services, which is crucial for end-user satisfaction. Theoretical foundations and possibilities of using artificial intelligence in network management and monitoring are presented.

The final part of the diploma thesis presents a practical example of such a network that contains all the characteristics of modern data centre architecture.
