A BRIEF HISTORY OF ESBs, APIs, AND MICROSERVICES

THE 90s Called – they want their tech back

ESBS CAME ABOUT FROM A NEED TO MANAGE PROTOCOLS.

INHERENTLY BUILT FOR HEAVY WEIGHT ARCHITECTURES FOR INITIATIVES THAT TAKE MONTHS.

THE REAL QUESTION: CAN YOU GET GOING FAST?

ANOTHER WAY OF SAYING THIS: ESB IS NOT A CONSUMPTION STRATEGY AND DEFINITELY NOT ONE BUILT FOR SPEED AND SCALE.

TO ESB OR NOT TO ESB

•  PROS •  CONNECTOR ORIENTATION

•  CONS

•  MESSAGE ORIENTED ARCHITECTURE

•  TOO MUCH WORK FOR VERY LITTLE OUTCOME

•  DOES NOT SCALE

•  DOES NOT PROCESS AT SPEED

•  TAKES TOO LONG

•  DEATH BY TRANSFORMATION

WHERE TECH TEAMS STRUGGLE

•  Too much to do •  Can’t deliver fast enough •  Not enough resources to support

all business needs •  Business stakeholders add

requirements as new needs arise

MICROSERVICES NIRVANA

Data Data Service Service

Service Service Service Data

Workflow Processes Apps Widgets

Web UI Mobile UI User Layer

Consumption Layer

Service Layer

WHY IS THIS HARD

EASY INTEGRATIONS •  Simple data syncs to support ad hoc reports

•  One-way data calls to systems of record

•  Simple email notifications

HARD INTEGRATIONS •  Automated workflows that eliminate error-prone,

manual work

•  Continuous data synchronization to enable always-right dashboards

•  Real-time availability of data in the system business stakeholders use

•  Asynchronous usage of microservices

BEST PRACTICES FOR CREATING MICROSERVICES

•  Atomic, usage first orientation (i.e. focused around enabling business outcomes)

•  Built to be absorbed through the network

•  Built-in failure tolerance

•  Completely stateless

•  Horizontally scalable

•  Follow a request-response pattern

•  Expose consumption blueprint

Azuqua is the consumption platform for the APIs, microservices, and processes to power the agile, digital enterprise
