The basis of a cloud engineer’s skill set is mastering primary cloud platforms. But still, apart from their knowledge of cloud systems, there are other technical skills and soft skills that engineers need to pay attention to if they want to become effective. In the following section, we shall discuss why it is important for one to have an idea about the principles behind designing and constructing clouds.
Understanding Cloud Architecture and Design Principles

Cloud architecture refers to everything involved in cloud computing such as front-end platforms, back-end platforms, networks and delivery models which may be public or private among others. Understanding this helps in creating scalable reliable cost-effective solutions on the cloud.

Key Components of Cloud Architecture:

Front-End Platform: These are devices used by clients or customers who want access to various services provided via the Internet or any other network connection. Examples include web browsers, thin clients, and mobile applications.

Back-End Platforms: Servers together with storage facilities required for keeping data needed when running programs are part of back-end components used by service providers (SP) while offering them to users (U). They also comprise databases where all information about different accounts registered with SPs can be found among others.

Cloud-Based Delivery: Deployment models like hybrid clouds which combine both private and public clouds within one organization could also fall under this category depending on what you mean when saying so otherwise just mention public or private only.

Network: The infrastructure connecting user interface device location which could be anywhere with servers running specific application program interfaces designed for use by people who do not own those computers themselves but would like access to some form of service provided over the internet such as online banking systems among others.

Design Principles:

Scalability: Systems must be able to scale up when there is a high demand for processing power but scale down again once that demand reduces. For example; AWS has an auto scaling groups feature while Azure offers a virtual machine scale sets facility.

  1. Reliability: This refers to how well a system can recover from failures quickly and reliably. There should always be backup systems in place that are capable of taking up where the main ones left off without causing any noticeable service interruption hence AWS has an elastic load balancer while Azure provides a traffic manager which could help achieve this objective more effectively.
  2. Security: Security measures need to be implemented at every level starting with data encryption, identity management plus access controls down through network security within cloud environment itself.
  3. Cost Management: Selecting appropriate services can greatly contribute towards efficient cost management as well utilization of tools like AWS cost explorer or Azure cost management could also play a crucial role in achieving this goal too.
  4. Performance Optimization: The best available resources on the cloud should always be used such that they are able to perform optimally for instance by choosing right types of instances together with storage solutions among others.
