I disagree, in my opinion micro-services hinder scalability of deployment, and development - at least the way I see most businesses use them. Typically they break out their code into disparate repositories, so now instead of one deployment you have to run 70 different ci/cds pipelines to get 70 microservices deployed, and repo A has no idea that repo B made breaking changes to their API. Or lib B pulled in lib D that now pollutes the class-path of lib A, who has a dependency on lib B. Often you need to mass deploy all of your microservices to resolve a critical vulnerability (think log4shell)
The solution to this is to use the right tool, a build system that supports monorepos like Bazel. Bazel solves this problem wonderfully. It only builds / tests / containerizes / deploys (rules_k8s, rules_docker) what needs to be rebuilt, retested, recontainerized, and redeployed. Builds are much faster, developers have God like visibility to all of an organizations' code, and can easily grep the entire code base and be assured their changes do not break other modules if Bazel test //... passes. It is language agnostic so you can implement your services in whatever language best suits it. It allows you to more easily manage transitive dependencies, manage versions globally across your org's codebase.
Of course Bazel has a steep learning curve so it will be years before it is adopted as widely as Maven, Gradle etc. But in the banks I've worked at it would've saved them tens of millions of dollars.
Also git would need to catch up to large codebases. I think Meta released a new source control tool recently that is similar to git but could handle large monorepos.
