This document compares bento boxes and sushi restaurants to microservices architecture. Bento boxes represent individual microservices that contain all the necessary components for a self-contained meal, while sushi restaurants represent monolithic applications where many chefs collaborate to feed customers. The document discusses how microservices provide focus, independence, and flexibility similar to individual bento boxes, but coordination and governance of interdependent microservices can become complex, as sharing items from different bento boxes. It concludes that both approaches have merits, and freedom to choose the right approach for each situation is important.

1. Sushi, Bento and
Microservices
japanese food to help to see software

2. Sushi Restaurant

3. What Is Bento?
Bento is a single-portion takeout or home-packed meal. Traditional
bento holds rice, fish or meat, with pickled or cooked vegetables,
usually in a box-shaped container. Containers range from
disposable mass produced to hand crafted lacquerware. Japanese
homemakers often spend time and energy on a carefully prepared
lunch box for their spouse, child, or themselves. [WIKIPEDIA]

4. Bento is Not Sushi Restaurant!
In modern Restaurant some ribbon make it possible to consume
patterns of little portions of sushi; in the middle, a powerful set of
sushi-master repeatedly produce enough sushi to make it possible
for everyone to eat. Ehi!...but this is the Monolith!

5. Bento Art
In little box you can be focused on details and create Art since
everything is clear and you can easy take control.
Size is Important: smart things can be done if you master your
creation and you can stay focused!

6. ...but Restaurant!
In sushi restaurant everyone can eat, maybe sometime you need to
wait to obtain the right dish you wish but, however, you will be fed!
If you want feed more people you increase the number of sushi-
master...
In the Monolith, if everything can work, everyone will take the
result of service invocation; if you increase resources, you can offer
more...but we already know: there are some limits!

7. Bento is Good!
Using the Bento everyone has a little box with everything needed to
eat: no wait, no delay, all is easily available!
The box can be easily moved, you can eat a little and resume later.
You can decide how to eat because everything is already there: the
user need only to open the box, look what inside and consume!
A Microservice is specialized software, in the past we would call it
Component, but a Microservice is more focused than a Component
You can move it for more and different deploy. You can easily use
it: there's a simple and effective interface
A Microservice can be complex, but normally, whom has built it, is
able to master it

8. Bento and details
Bento is homemade by mom or by yourself with patience and love
Microservices are built by little a team aware of what they want to
achieve and they do their best. They master every aspect of
Microservice they built!

9. Bento is not good to share!
What if, people on the same table, want to
share elements of their Bento?
● maybe who is faster, he will eat better
● maybe everyone is polite but the
organization create delay, difficult decisions
or some food is wasted
● maybe favourite things aren't enough and
everyone is unhappy
● maybe someone propose to go to restaurant

10. Bento & Microservices (1/2)
To make collaborative Microservices can be a serious problem
● which protocol to use?
● how to avoid chaotic or chatty communication?
● how to preserve reuse and clear bounds of services?

11. Bento & Microservices (2/2)
Governance of Microservices can be difficult:
● you need some more smart thing than a
Registry
● you need to monitor fast evolutions
● if every microservice team is indipendent,
you need to govern teams very well
● you need rules wise enough to be adopted but
without constraint on the teams
● you must be able to afford trashing services
and be fast enough to build new ones

12. …So...At the End?? (1/2)
Bento Art is amazing...but better if you can decide between use a
Bento that day or go to Restaurant! Freedom to choose it's
important and so, it's important to be aware of the consequences.
You're ready?
Also it's important to have good friend with which eat and however
someone that able to be a great cook, maybe tomorrow he will
prepare amazing Bento for you!

13. …So...At the End?? (2/2)
If you need to feed some Business Partners, you'll decide to go to
restaurant...but you're always sure of the restaurant that you
choose?!?!?
...better to be able also to make an amazing Bento to surprise
everyone!
