Cloud capacity planning is the process of estimating and allocating the optimal amount of cloud resources for your applications and services, based on your current and future needs and goals. To do this, you must first understand your business requirements and objectives, such as key performance indicators, service level agreements, and customer satisfaction metrics. Additionally, you need to be aware of market trends, customer behavior, and competitive factors that may affect your demand and growth. After that, you must estimate how much cloud resources you need for your applications and services by considering peak hours, seasonal fluctuations, special events, user behavior, and any potential risks. Lastly, you must allocate the appropriate amount and type of cloud resources for your applications and services while accounting for performance, availability, scalability, security, and compliance. Comparing different cloud options and configurations will help you choose the best value and fit for your needs.
