Not every product needs AZ from the start (specially for small teams or solopreneurs), in most cases you&#x27;ll be doing over-engineering. And in the use cases you need AZs and <i>do it right</i> new tools like convox* are really easy to use and can save you a lot work. It&#x27;s never been this easy to manage your own infrastructure.<p>During the years I&#x27;ve used ssh, puppet, fabric, ansible, capistrano, cloud formation, etc for managing servers and infrastructure. And I think that the main benefit of any PaaS, AWS Lambda or AWS API Gateway is (obviously) that they&#x27;re time saving and abstract the internals. In fact I use them in several <i>small</i> projects.<p>* <a href="https:&#x2F;&#x2F;www.convox.com" rel="nofollow">https:&#x2F;&#x2F;www.convox.com</a>
