Changing views on integration – from Enterprise Service Bus to API Gateway, Serverless and iPaaS

Lucas Jellema January 23, 2019 1

If your tool is a hammer, every problem looks like a nail. Many of us have seen situations where this tunnel vision over time took hold. And for many of us involved in integration, this also has happened. In this article I want to briefly draw your attention to changing […]

Maarten Smeets July 13, 2018 1

There are numerous occasions that I was limited in my work because of connectivity which could not be trusted. For example; I could not download large installers due to a proxy anti virus tool which manipulated downloads causing files to become corrupted. I needed to visit a website to find […]

Industrial IoT Strategy, The Transference of Risk by using a Digital Twin

Robbrecht van Amerongen July 25, 2017

The Internet of Things (IoT) is all about getting in-depth insight about your customers. It is the inter-networking of physical devices, vehicles (also referred to as “connected devices” and “smart devices”), buildings, and other items embedded with electronics, software, sensors, actuators, and network connectivity which enable these objects to collect […]

SSL/TLS: How to choose your cipher suite

Maarten Smeets July 4, 2017 3

For SSL/TLS connections, cipher suites determine for a major part how secure the connection will be. A cipher suite is a named combination of authentication, encryption, message authentication code (MAC) and key exchange algorithms used to negotiate the security settings (here). But what does this mean and how do you […]

Microservices in the world of the red giant – report from Oracle OpenWorld 2016

Lucas Jellema November 1, 2016

Undeniably, microservices is an extremely hot term. A bandwagon almost every product team at Oracle seems eager to be jumping on to.

The Evolution in IT providing the backdrop to Oracle OpenWorld 2016

Lucas Jellema October 27, 2016

The backdrop for Oracle OpenWorld 2016 – or indeed all IT conferences – is the constant evolution in IT. On many levels – from hardware to philosophy – the ongoing fundamental developments open up opportunities and foster and sometimes accelerate change. To understand some of the directions taken by Oracle […]

What can we learn from the Microservices movement?

Lykle Thijssen September 25, 2016 1

If you’re into integration, SOA or web services, you’ve probably heard the term Microservices fairly often lately. Is applying Microservices architecture the one-size-fits-all solution that can replace the traditional one-size-fits-all SOA solution that doesn’t fit anymore? Of course not, because the world isn’t just black and white and both architectural […]

Saving money by understanding Oracle licensing, part 1

Job Oprel August 26, 2016

Oracle and licenses. The general feeling most of the time is that you pay too much for the use of the Oracle products, and it’s not always sure if you are compliant, because of the complexity of the rules. This – hopefully clarifying – blog is part of a small […]

Utilizing your IT environment with Oracle Database Appliance

Job Oprel July 20, 2016

Network considerations on an ODA X5-2

Jaap Poot June 24, 2016

When you buy an Oracle Database Appliance (ODA) X5-2 off the shelve, you will get a machine with four times 10Gb copper Ethernet (bonded into two interfaces) for public communication and two 40Gb InfiniBand (bonded into one interface) for interconnect communication between the two ODA_BASE’s. You would think that should […]

Oracle Database Appliance X6-2S and X6-2M, filling the gap

Simple problems and simple solutions

Luc Gorissen March 31, 2016

Most developers have struggled with wires in SOA composites. You may find yourself in a situation where a wire has been deleted. Some missing wires are restored by JDeveloper. Other missing wires have to be added manually, by simply re-connecting the involved adapters and components. Simple. Recently, I had […]

Migrating Red Hat Linux subscription to Oracle

Oracle Public Cloud Confusion

Job Oprel February 17, 2016

I always thought I could address the main differences between private and public cloud. Oracle announced the ‘Oracle Private Cloud Machine’ at Oracle Open World 2015 which runs locally, offering a private cloud for an organization. Then Oracle decided to rename it to ‘Oracle Public Cloud Machine’. And I think […]

Oracle Cloud en de Europese Privacy regels; waar moeten we op letten?

Sander Mastwijk December 7, 2015

Als Oracle gebruiker ziet u de mogelijkheden van de Oracle Cloud. De grote flexibiliteit, de mogelijkheid om capaciteit bij en af te schalen, instant diensten en het maandelijkse verrekenmodel. Alleen al de korte doorlooptijd voor (tijdelijke) omgevingen en de verminderde beheerinspanning kunnen leiden tot een flinke verbetering in efficiëntie. Zo bent u minder bezig met de dagelijkse operatie van […]
