Cloud Computing - Concepts and Technologies

Cloud Computing is an IT paradigm that enables using hardware, middleware and software in a pay-per-use manner. Cloud resources can be provisioned dynamically and users only have to pay for the actual usage, which helps to handle peak workloads. Cloud providers such as Amazon, Google, and Microsoft offer many different kinds of Cloud services that can be used by customers for deploying applications.

This lecture explains the basic concepts of Cloud Computing and discusses different kinds of Cloud technologies in exercises. The lecture starts with fundamentals and provides deep insights into the following Cloud-related topics:

• Service Models & Deployment Models (NIST Layering)
• Scalability & Elasticity
• Virtualization (Virtual Machines, Hypervisors, OpenStack)
• Cloud Architectures (Loose Coupling, RPC vs. Messaging, Cloud Native, Cloud Immigrant)
• Cloud Providers (Amazon Web Services, Microsoft Azure, Google Cloud Platform)
• Containerization (Docker & Kubernetes)
• Data in Cloud Computing (NoSQL, CAP, BASE, Lambda Architecture)
• Cloud Application Provisioning and Management Paradigms (Declarative vs. Imperative)
• Cloud Application Provisioning and Management Technologies (TOSCA, Chef, Puppet, etc.)
• API Management (REST, Swagger, Security)
• Cloud Computing Patterns
