Microservices in an Integrated World A Hybrid Approach

10


If it Wasn’t for the Canonical...

11


• Is it small?

• Does it run in an Application Server?

• Does it use XML?

• Does it use REST?

• Does it use SOAP?

12

What is a Microservice?


Benefits of a Monolith

• Common code infrastructure

• More density/efficient allocation of hardware

• Not Everybody has to be an expert in security.

• Developers do not have to develop instrumentation into their services

• Less inter-process communication required, less network hops

13


• Extreme Scalability

• Organizational Ownership

• Cheaper to Start

• Ideal for the Cloud

• Grasp latest technologies

• Promotes Agile Practices

• Promotes DevOps

• All Programmers Welcome!

• “It’s what the cool people do!”

14

Benefits of a Microservice Approach


• Leverage common management/monitoring

• Scale out with in-memory data-grid

• Common transformation logic.

• Increase density

• Capture Business Instance Data over Choreography.

15

Hybrid Approach

Copyright © 2015, Oracle and/or its affiliates. All rights reserved. | 29-Oct-15 16

• Answers the key questions your data warehouse / BI solutions are not built for: – need current info – requires cross system

data – no coding /

instrumentation

Real-Time Dashboards


The Promise of Microservices vs. Monolithic Architecture Monolithic Microservices

Codebase Singular, unified, codependent Smaller, independently evolving

Technology Stack Homogeneous Best of breed

Edit-Compile-Test Minutes to hours Seconds

Dependencies Compile-time; version lockstep Network APIs; library independence

Change Slow, painful, risky Isolated; consumer-driven contracts

Rewrite Major planning One service at a time

Test & Release Months, all in one Focus on changed services

Deploy & Start Minutes to hours Seconds or less

Scaling All or nothing Hotspots

Operations Static, straightforward Dynamic, complex automation

21


Classic Problem of Constraints over Principles

• While adopting an architectural style; people often prioritizes restrictions over design principles, resulting in fragile/broken software architectures.

– e.g. Put as most logic as possible in the database due to the client/server style.

• Constraints must be evaluated carefully, considering context, organization culture, infrastructure limitations and of course, people's knowledge.

– e.g. Breaking down a 10 years old bank's corporate MDM into smaller entity services.

• By focusing in the principles, developers can design their services without sacrificing the entire architectural style. – Achieving loosely coupling even without exposing services through REST

– Handling failures/exceptions by design without coding in the application.

What is a Microservice Architecture (MSA)?

A

T

MSA

O

3 aspects to MSA

rchitectural

rganizational ecnical


• Common platform for all services deployed

to it

• Typically services/APIs runs on an AS, that

depends on an MRE

• Resources made available to and managed

by MRE and AS

• Multi-threaded with more overheads to

handle I/Os

• Use of containers (i.e. Dockers, Linux

Containers) less popular

• Common hardware for all services/APIs

running on the same ESB or Application

Server clusters

• Built on common governance and

standards

• Comm tech stack

• Contracts define service/APIs interfaces

• Granularity focused on business

capabilities

• Typically Services/APIs run on an ESB

• Use of Canonical schemas not

uncommon for business services, less

common in APIs

• APIs typically targeted for external use

(exposed in DMZ)

• HTTP transport of choice but multi-

transports supported

• Multiple message protocols supported

(SOAP-XML, REST-JSON, etc)

• DevOps / Continuous Delivery

becoming more popular not yet

mainstream

• Relaxed governance: less focus

on common standards and more

on people collaboration and

freedom of choice

• Use of ESBs not popular

• Granularity focused on business

capabilities

• Services/APIs are self-contained

an can run independently from

each other

• Services/APIs built using tech

stack of choice (usually one

that’s best for the job)

• Use of Lightweight protocols,

such as HTTP/REST and AMQP

• Strong focus on DevOps /

Continuous Delivery from the

start

• Services are stateless

• Single-threaded typically with use of

use of Event Loop (callbacks) features

for non-locking I/O handling

• Application Servers not really used.

Platforms such as Node.JS can be

used but not mandated (as said, no

tech stack enforced)

• Use of containers (i.e. Dockers, Linux

Containers) more popular as

services/APIs are more independent

on other applications

• Common hardware optional
