Multi cloud has long been a contentious topic when you talk about cloud infrastructure. Infrastructure as code tools such as Terraform and Pulumi have made deploying to any cloud much easier - you can now use a single interface to deploy infrastructure to virtually any cloud environment. However, the effort of creating infrastructure for each cloud provider still requires significant expertise and time to get right, leading many to see it as a effort not worth taking.

Nowadays, REST is ubiquitous across most kinds of applications. It provides an easy, simple and clear language to communicate between services, usually a frontend and a backend. Although, there are many good alternatives and I want to talk about one in particular - gRPC. From my days as a Software Engineer at Google, I have grown quite fond of gRPC. Google uses it everywhere, from communicating between frontend and backend, to communicating with database servers to all kinds of microservices.
