Sacha and his cofounder already developed the first version of their product. They are now undertaking the Version 2 of their development and are considering moving to Amazon Web Services (AWS) as their cloud hosting solution. Today I’m going to answer a question from Sacha, the co-founder of a B2B marketplace. His question is... What’s the difference between a server and a cloud hosting? Before answering this question, let’s add a bit of context.Sacha and his cofounder already developed the first version of their product. They are now undertaking the Version 2 of their development and are considering moving to Amazon Web Services (AWS) as their cloud hosting solution.Moving an application to the cloud is usually a very good option because you are not renting a server anymore but buying a delivered service instead.Let’s see how cloud services work. How the cloud works For example, AWS builds data centers all over the world with thousands of computers.When you use their services, you do not have one server attributed to your service. The service you buy will be dispatched across dozens of servers and even across several data centers.On this data center, you will have several services: Apps Hard drive/storage Artificial intelligence (AI) Backup Etc. That’s not one server that will be dedicated to one service, but a group of servers that will be dedicated to one service.And the beauty of a real cloud service is that you just need to worry about developing your application. If something goes wrong but everything is setup correctly, the cloud handles everything. You don’t even have a downtime.A downtime is a time when a server crashes, and your website will be down and not working. It doesn’t happen anymore when you are on a real cloud server.Cloud providers use what we call a load balancer which switches client requests from one server to another automatically.You don’t need to have an engineer 24/7 available. No need to spend days and weeks setting up manual architect
