Cloud and Infrastructure Engineering

Infrastructure as a Service (IaaS) is a cloud computing model in which companies rent IT infrastructure such as servers, storage, networks and operating systems from a third-party provider over the internet. Instead of buying and maintaining physical hardware, companies can utilise and scale these resources as needed, providing flexibility and cost efficiency. IaaS enables companies to quickly adapt their IT capacity to changing business requirements, while the provider takes care of the maintenance, security and availability of the infrastructure. This makes it easier to access innovative technologies and concentrate on the core business.

A public cloud is a cloud computing environment that offers resources such as computing capacity, storage and applications provided by a provider via the internet. This infrastructure is shared by several customers and made accessible via a global network of data centres. Public clouds offer companies scalability, flexibility and cost efficiency, as they only have to pay for the resources they actually use and do not have to manage their own physical infrastructure. They enable companies to react quickly to changing business requirements and utilise modern technologies such as artificial intelligence and big data.

Platform as a Service (PaaS) is a cloud computing model in which companies utilise a complete development and deployment environment via the Internet from a third-party provider. PaaS provides an integrated solution that includes resources such as servers, storage, networks, databases and development tools. This platform enables developers to quickly create, test, deploy and manage applications without having to worry about the underlying infrastructure. PaaS promotes efficiency and productivity by reducing the complexity of infrastructure management and enabling developers to focus on programming and innovation.

A hybrid cloud combines the advantages of public and private clouds by creating an integrated IT environment that runs both locally in a private data centre and in a public cloud. Companies can keep sensitive data and critical applications in the private cloud while utilising the flexibility and scalability of the public cloud for less sensitive workloads. This hybrid architecture enables companies to optimise their existing IT infrastructure and use resources efficiently while maintaining security and control over their sensitive data. Seamless integration also allows companies to benefit from innovative cloud services and dynamically adapt their IT resources to respond to changing business requirements.

Software as a Service (SaaS) is a cloud computing model in which software applications are provided as a service via the internet. Companies and individuals can access and use these applications without having to install or maintain them locally. SaaS providers take care of hosting, maintenance, security and updates of the software, ensuring that users always have the latest version and features available. This model offers flexibility, scalability and cost efficiency, as users only pay for the services they actually use, eliminating the need for extensive IT infrastructure. SaaS facilitates collaboration and access to applications from anywhere, which is particularly beneficial in mobile and decentralised working environments.

A multi-cloud environment refers to the use of multiple cloud services from different providers, either simultaneously or sequentially, to support different applications and workloads. Organisations may choose multi-cloud strategies to avoid dependency on a single provider, increase flexibility and leverage the best solutions for specific tasks. By distributing workloads across different cloud providers, companies can also optimise costs, improve performance and ensure that they can meet the specific requirements of their applications. However, the challenge is to effectively manage integration, security and administration across different cloud platforms, which requires specialised tools and strategies to create a coherent multi-cloud environment.
