This course covers the core learning objective to meet the requirements of the 'Implementing effective Cost Management solutions in AWS - Level 1' skill

Learning Objectives:

  • Understand aspects of AWS Cloud economics, including OpEX, CapEX and TCO
  • Understand the various AWS account structures in relation to AWS billing and pricing practices
  • Understand which operations will reduce costs by moving to the AWS cloud
  • Analyze and contrast the various pricing models for AWS, such as On-Demand EC2 Instances, Reserved Instances, and Spot Instance pricing

You've probably heard this one here before: DevOps. DevOps is a set of practices that intends to break down traditional silos between developers and operators of computer systems, allowing combined teams to collaborate and deliver software in a more consistent, efficient and automated fashion.

Enterprise Architecture, or EA, groups are traditionally tasked with outlining the structure of the systems an enterprise will build and maintain to achieve its business goals. Like physical architects, they provide the blueprints for how the various systems should be put together, the "materials" or software concepts that should be used to build them, and how the end results should look.

Lift & Shift. Lift & Shift is a method of migration involving moving an application as currently architected and built from one environment (an on-premises data center) to another (usually a public cloud). Lift & Shift migrations can usually be done more quickly as they often do not require substantial change to the application code or configuration.

However, because they do not modify applications to use cloud-native services, they tend to create situations where the cloud system is more expensive or difficult to run than the on-premises system had been. 

Lift & Shift migrations are typically used when time pressure to close a data center or other need outweighs the cost and quality issues. A remediation period for the environment should always be planned After a Lift & Shift migration to address issues.

Workload is a generic name for an application or software system running on a computing or other platform.

In a traditional website, there might be a web server, an application server and a database server, each running on an individual hardware-based server, or virtual machine in my data center, each of those three elements of the application would be a workload running on that virtual server. 

On-Premises (or On-Prem) is a term used to refer to company-owned or company-controlled data center space. Usually used to differentiate from public cloud environments where application migrations are targeting workloads.

Companies have an extensive On-premises infrastructure built over many years when they begin using the cloud, and there are often difficulties using systems, infrastructure or processes developed for the on-premises environment in the public cloud.

Rightsizing is a form of optimization where measurements are taken over time to match workloads to a virtual resource sized to run it efficiently with a minimum of waste. Rightsizing can be used as a technique to save costs but must always involve technology oversight as well.

Agile is a method of project management, used primarily for software development characterized by division of tasks to short phases of work (into sprints) and frequent assessment of priorities and plans. Generally, leads to development of products or software incrementally beginning with a minimum viable product and then continually enhancing it from a backlog of requirements.
