MICROINTERACTIONS AND MICROSERVICES

LITTLE THINGS MATTER!

Angelo Oldani & Roberto Nocera

Designers and engineers were motivated

to think big, to design massive systems

Getting the picture right is correct butwe need to focus on the little things as well

We need to focus on the details in order to

create remarkable digital products and

services

People love details

they allow your product to stand

out from the rest

Delivering details means

delivering emotions

Microinteraction: atomic element, a sort

of interaction that cannot be broken down

into other interactions

Other examples are:

Like something

Nest Thermostat

Share something

Change a setting

Export something from your app

Give a rating

4.5 Billionaverage number of likes generated daily

A step head of usable

Functional

Reliable

Usable

Pleasurable

Aarron Walter, Designing for Emotion

Do microinteractions mean features?

Features are related to multi use cases, time

consuming and cognitively engaging

Microinteractions are related to single use

case, brief and effortless

Thanks to Dan Saffer who inspired me to study this topic. Some of the content of this presentation is taken

from his book: Microinteractions, designing with details.

The microinteraction framework

Trigger Rules Feedback Loops & Modes

Analyse a microinteraction

How can we incorporate microinteraction

into our process?

Look for them and focus on each individually

Reduce complicated features into microinteractions

Treat every feature as a set of microinteractions set

together

What is the secret to deliver

microinteractions?

Evolution

Component as a service

Replace and upgrade independently

It’s not about how we think software is build

but how users use the software

When we have components we can build

libraries

Now we can use services with the same approach

Smart endpoints

Usually enterprise think about Enterprise

Service Bus

In the microservices there is the concept of smart endpoints

Decentralization data management

▪ Monolith approach usually works with a relational db

▪ Single db solution of the whole monolith

▪ Each service gets its own data storage

▪ It does not share that data directly with anybody else

▪ Each service chooses what database to use not just the schema

Design for failure

Design the code to manage failure in order to minimize the impact on the user

People are aware of the fact

that things will break

Monitor and recovery

Infrastructure automation aka continuous delivery

Devops rules, tools are your fiends

Big changes for the organization

Conway’s law : the software will follow the

organization to the people chosen to build

Microservices is as much about team organizational

attitude as it is about technological attitude

User Interface

Business logic

DB

Product Catalog

Basket

Payment process

Are microservices just SOA?

It depends on what do you think is SOA

A Microservice definition : loosely coupled service oriented architecture with bounded contexts

Use the right approach

MONOLITH

Simplicity (microservices required

asynchronous calls)

Consistency (vs availability)

Change the shape of the code (in case of refactor using the

same code base)

MICROSERVICES

Partial deployment

Availability

Preserve modularity

Multiple platforms

Component as a service

Deploy applications rapidly

Monitoring in place

Continuous delivery (rollback easily)
