What is a Microservice? • Is it small? • Does it run in an Application Server? • Does it use XML? • Does it use REST? • Does it use SOAP?
Copyright © 2015, Oracle and/or its affiliates. All rights reserved. |
12
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
Copyright © 2015, Oracle and/or its affiliates. All rights reserved. |
13
Benefits of a Microservice Approach • 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!” Copyright © 2015, Oracle and/or its affiliates. All rights reserved. |
14
Hybrid Approach • Leverage common management/monitoring • Scale out with in-memory data-grid • Common transformation logic. • Increase density • Capture Business Instance Data over Choreography.

Real-Time Integration Business Insight
Real-Time Dashboards
• Answers the key questions your data warehouse / BI solutions are not built for: – need current info – requires cross system data – no coding / instrumentation 29-Oct-15 Copyright © 2015, Oracle and/or its affiliates. All rights reserved. |

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.

MSA - Technical 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 multitransports supported Multiple message protocols supported (SOAP-XML, REST-JSON, etc) DevOps / Continuous Delivery becoming more popular not yet mainstream
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

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
