Why is service mesh paramount?

There are a few compelling reasons and causes for the successful introduction and the runaway success of service mesh solutions. Microservices has emerged and evolved as the most appropriate building block for enterprise-grade applications and the optimal unit of application deployment. Furthermore, deploying a number of microservices rather than big monolith applications gives developers the much-needed flexibility to work in different programming languages, application development frameworks, rapid application development (RAD) tools, and release cadence across the system. This transition is resulting in higher productivity and agility, especially for larger teams.

There are challenges as well. The problems that had to be solved once for a monolith, such as security, load balancing, monitoring, and rate limiting, need to be tackled for each microservice. Many companies run internal load balancers that take care of routing traffic between microservices. The...
