Microservices Explained for those with Humour

Let's talk about microservices - the hot new trend in software development that promises to revolutionise the way we build and deploy applications.

Revolutions are good... right? They happen on a regular basis when people are fed up with the status quo. Like disposing of Louis XVI of France and Nicholas II of Russia. Yet disposing of Louis and Nicholas had consequences and were particularly bloody.

Will microservices cause a software developer bloodbath? Hopefully not, as software developers are known for being loving and peaceful people. But to be sure, let's examine the pros and cons of microservices to see what kind of world they advocate and whether this world is worth living coding in.

Pros:

• Microservices allow for faster development and deployment. Instead of having one big monolithic application, you can break it down into smaller, more manageable chunks. Think of it like a Lego set - if you want to add a new feature, you don't have to rebuild the whole castle, you can just add a new piece. It's like having a personal chef for each dish, instead of having one chef cook everything at once. To be honest, in my kitchen, even just having one chef would be an improvement.
• Microservices also make it easier to scale your application. If one service is getting slammed with traffic, you can simply spin up more instances of that service to handle the load. This is like having a buffet line where you can just add more chefs to the kitchen instead of having one chef cook everything at once. And you don't have to worry about the other dishes getting cold while waiting for the main course. This could lead to weight problems. Microservices developers... look out!
• Microservices also make it easier to maintain your application. If one service goes down, it doesn't take the whole application with it. This is like having a car with a flat tire - you can change the tire and keep driving, instead of having to replace the whole car. It's a lot less stressful, and you don't have to worry about the whole car falling apart if one wheel goes out of order. This is why I love trains.
• Microservices can also make it easier to update and upgrade your application, as you can deploy new versions of a service without impacting the entire application. It's like having a software version of a patchwork quilt, where you can add new patches without affecting the whole quilt. Does this mean microservices developers are more domesticated?

Cons:

• Microservices can be a bit of a pain to set up and configure. It's like trying to assemble complicated IKEA furniture - you'll need to spend a lot of time looking at instructions and figuring out where all the pieces go. It can be frustrating, and you might end up with extra screws and pieces left over. I grew up with IKEA. Frustration can indeed get bloody, especially when key pieces are missing or don't fit!
• Microservices can also lead to increased complexity. With multiple services interacting with each other, it can be difficult to keep track of how everything is working together. This is like trying to make a soufflé - you need to be careful not to mess up the balance of ingredients or everything falls apart. And you'll need to be careful, to not overcomplicate the recipe, or your souffle will fall. I don't like soufflé but neither do I like complexity so this is a bit of a conundrum.
• Microservices can also lead to increased communication overhead. With multiple services talking to each other, you'll need to make sure they're all on the same page. This is like trying to organize a group of friends to go out to dinner - it can take a while to get everyone to agree on a restaurant. And if one person is not on board, the whole plan falls apart. Assuming you have enough friends of course.
• Microservices can also lead to increased operational costs, as you'll need to manage and monitor multiple services, which can be expensive. It's like having a big party, where you need to hire multiple caterers, DJ, and entertainers, and it can cost a fortune. Possibly not worth it, unless the DJ is Van Buuren.

In conclusion, microservices can be a powerful tool for building and deploying applications, but it's important to weigh the pros and cons before diving in. Just remember, it's like a buffet line, you can add more chefs to the kitchen, but you also need to be careful not to mess up the balance of ingredients or everything falls apart. And don't forget to keep an eye on the bill expenses!
