_Cloud Cost Optimization

In most cases, this category concerns misconfigured or completely redundant resources but does not affect the solution architecture. The turnaround time is days, and sometimes just hours. Very often, we can see the effect of lower costs the next day.

Examples:

• Configuration changes
• Costs avoidance
• Elimination of waste

In that category, we face problems that require more planning. Additional analysis of the potential impact on other components or services of the organization is often required. This is especially important in the case of irreversible operations, e.g., termination of potentially redundant resources that were initially uncertain. For this reason, we can expect cost reductions within days or weeks.

Examples:

• Service substitution
• Elimination of waste
• Rightsizing

This category always requires significant changes to the architecture of a solution that are never quick or easy to implement. Hence, a work period of several weeks must be considered before the estimated savings are achieved.

Examples:

• Implementing the Cloud Native concepts like Serverless
• Migration of Lift&Shift to more elastic architectures
• Spot Instances implementation
