Step-by-step explanation:
Organization that has migrated their highly customized external websites into the cloud.
One example of an organization that has migrated their highly customized external websites into the cloud is Netflix. Netflix moved their infrastructure from traditional data centers to Amazon Web Services (AWS) in order to improve scalability, reduce operational costs, and increase flexibility. By leveraging the cloud, Netflix is able to handle large amounts of streaming traffic and deliver a seamless user experience.
Another example is Expedia, an online travel company. Expedia migrated their websites and applications to the cloud to reduce the complexity and cost of managing their infrastructure. This move allowed them to focus more on innovation and improving their customer experience.
In both cases, the organizations took advantage of the cloud's scalability, reliability, and cost-effectiveness to support their highly customized external websites.
