Description
Welcome!This is an introductory course on Cloud Computing, aimed at beginners, managers, and anyone who wants to approach the topic. We combine theory and experience. First hand experience, gained in around ten years working on cloud-native applications and application migrations to the cloud. And theory coming from industry experts, integrated with statistics and market trends.We will introduce different topics such as models, technologies and so on, integrated with considerations about related advantages and disadvantages. At the end of this course, you will have an overview not only about main concepts, but also a good understanding about what challenges may come.We will see that not all cloud projects succeed in delivering expected value. We will see why this happens. And how we can increase chance of successful implementation, for a correct cloud adoption.Here what you will find:What is the cloud computingThe cloud in a nutshell. From the evolution toward the Cloud, to the definition of the Cloud Concept, introducing its main characteristics and founding models. In detail, we will analyze the strengths and weaknesses of the models presented.Lessons in this section:The evolution towards the cloudService Models: IaaS, PaaS, SaaS and pros/consDeployment Models: private, public, hybrid and pros/consCloud characteristics: vertical/horizontal scalability and other characteristicsCloud infrastructure and technologiesDescribing main infrastructures and technologies forming the Cloud landscape. We will get an introduction of main concepts like Kubernetes, Pods and Namespaces, and we will see how the infrastructure has been organized to deliver what promises.Lessons in this section:Virtualization, containers, distributed systemsNodes orchestration and KubernetesPods, Namespaces, OpenshiftData centers, redundancy, replication and backupNetworks and storageSecurityCloud servicesCloud adoptionShould we migrate to the cloud? If so, what are the challenges we are going to face? And how to migrate? Should we go for one of the hyperscalers? This section aims at replying these questions.Lessons in this section:Should you move?CostsPublic providersCloud Native and ServerlessOther patternsCloud trendsWhere is heading the cloud? What are the main challenges its users are facing? What are the requirements for its next generation? We are going to see how organizations are replying to the challenges we have started to perceive in previous sections.Lessons in this section:Some statisticsTop trends: multi-cloud, cross-cloud and IA/MLOther trends: Edge computing, advanced security, …Cloud dissatisfaction and repatriationNext generation requirementsYou can follow the lessons, or you can find the transcriptions and the slides in the Conclusion section. At the end of each chapter there is a quiz to check your understanding.
