The first law of distributed systems is, don\u2019t distribute! <\/p>\nM. Fowler<\/cite><\/blockquote>\n\n\n\n

If you still feel the need to consider moving to a distributed architecture then microservices is a good alternative to a monolith.<\/p>\n\n\n\n

Robust and Stable<\/h5>\n\n\n\n

Microservices encourages a design where components are highly cohesive and have low coupling. This is an implicitly stable design.<\/p>\n\n\n\n

Scalable<\/h5>\n\n\n\n

A monolith needs to be scaled as one entity, in a microservices architecture, every service and its underlying database can be scaled independently.<\/p>\n\n\n\n

Ease of deployment<\/h5>\n\n\n\n

Modifying a monolith in production is like changing the wheels of a car as its moving. Deploying changes in a microservices architecture is more like a tire change at a F1 pitstop.<\/p>\n\n\n\n

Teams can quickly make changes, fix bugs without stepping on each other teams toes.<\/p>\n\n\n\n

Why are organisations adopting Microservices?<\/h3>\n\n\n\n

Here is a quote from Sam Newman that pins this down.<\/p>\n\n\n\n

\n

…the single biggest reason that organisations adopt microservices is to allow for more developers to work on the same system without getting in each others way<\/p>\nSam Newman<\/cite><\/blockquote>\n\n\n\n

Should you use Microservices?<\/h3>\n\n\n\n

Are you a small team?<\/h5>\n\n\n\n

There is a vast ecosystem of great open source tooling that can help you setup your own microservice architecture. However, if you are a small team, its probably not a good idea to \u201croll your own\u201d.<\/p>\n\n\n\n

We made this mistake. Our log aggregation SaaS was initially built with a self assembled stack that was really a distributed monolith. We spent weeks on plumbing and reliability rather than on features that delivered actual business value. Juggling all the moving parts in our stack took a lot of effort.<\/p>\n\n\n\n

Small teams should really invest time on the business value of their software and use managed services by AWS, GCP or Azure to take care of the microservices infrastructure.<\/p>\n\n\n\n

Are you a large team?<\/h5>\n\n\n\n

If you are a large team and having difficulties or even teething pains with your monolith, then it would be a good idea to consider incremental steps towards microservices. One of the best analogies, I\u2019ve heard here is to think of microservices as a volume dial. Changes should be introduced step by step and not 0 to 10.<\/p>\n\n\n\n
