Azure is where Microsoft is investing heavily, offering a range of services at competitive prices. Cloud computing involves running applications in someone else's data center, appealing to enterprises that want to focus on their core expertise rather than managing infrastructure. The concept is likened to ordering pizza, where the company handles the entire process while the customer focuses on what they do best. Many companies are moving to Azure due to its benefits, including scalability and cost-effectiveness. Signing up for Azure is straightforward, requiring only a Microsoft account and credit card information. The platform offers free services, but some features, such as Couchbase Server, require a $200 trial credit. Quotas are in place to prevent unexpected expenses, and users can request increases to their limits if needed. Overall, Azure provides an accessible entry point for those new to cloud computing, with many resources available to help get started.
