About the course

Cloud Computing is expected to generate trillions of dollars in revenues over the next few years. Companies are adopting the trend to cut costs and speed up the development and deployment of state-of-the-art applications. Therefore, cloud computing skills will continue to be in high demand. There is no better time than now to start your cloud career journey.

Newcomers to cloud computing could come from various backgrounds. Based on our experience at DolfinED with more than 100 thousand students, many come without IT background or without broad knowledge of crucial topics that are key to the learning cloud. Topics such as encryption, networking, TCP/IP addressing, application architectures, containers, virtualization, and more. This course tries to provide a high-level overview for these newcomers to ensure they can fully grasp the knowledge a cloud professional is expected to know.

The course provides a high-level introduction to the following topics, which is enough to facilitate understanding related services in cloud computing and IT in general:

  • IP Addressing 101 (Binary number introduction, IP address types, IP Address subnets, Subnet Masks.
  • TCP/IP Packet anatomy (understanding packet headers).
  • IP Routing 101.
  • Static vs. Dynamic Routing 101.
  • OSI vs. TCP/IP Reference Models.
  • Network Address Translations (NAT) 101.
  • Port Address Translation 101 (PAT).
  • Virtualization 101.
  • Monolithic vs. Multi-Tier Application Architectures.
  • Encryption 101.
  • TLS/SSL Digital Certificates.
  • More lectures are added as required to facilitate Cloud learning; got a topic you want to see here? Get in Touch.
