9 items to consider when selecting an API Manager

9 items to consider when selecting an API Manager

17 april 2019 Roger van de Kimmenade
One of my hobbies is photography and when I bought my first camera it was a compact camera. I soon realized and experienced that I needed a reflex camera (SLR), because the resolution, speed and quality was far more better. I did not realize it until I really used the product. The again after a few years I noticed that I did not use my camera a lot. Why was that? Because the camera was pretty big and unpractical to take with me all the time. Then I read about a system camera, which has the advantage of being small, but still has the possibility to switch lenses. I never regretted my choices, because at the time it seemed to be the best choice. Today there are a lot of camera’s with lots of possibilities and specifications. Which one to pick? This depends on a lot of factors. What do you want to photograph with the camera. What type of photographs do you want to take, for example portret-, landscape-, sport- or street photography.

17 april 2019 Sander van Laar
Als je werkzaam bent in de ICT, dan heb je vast gehoord van het CAP-theorema: voor een gedistribueerd systeem is het onmogelijk om tegelijk te voldoen aan alle drie de aspecten Consistency, Availability en Partition Tolerance.

Custom CloudWatch Metrics – revisited

Custom CloudWatch Metrics – revisited

5 maart 2019 Milco Numan

In my previous blog I have investigated how to create custom metrics for an EC2 instance using Python and Boto3, the AWS SDK for Python. At the time I was specifically interested in demonstrating that it was not necessary to use these “old fashioned” PERL scripts to post custom metrics from your EC2 instance, but you could also do this yourself rather easily using Python. All steps I’ve taken in the process have been performed manually, but that’s not really something you’d like to do whenever there’s more than [insert your threshold here] instances to provision.

Java User Group 7 & 8 Februari

Java User Group 7 & 8 Februari

# Introduction

Although I have never read “Clean Code”, by Robert “Uncle Bob” Martin, it’s known as one of the books you have to read if you want to grow as a developer. Writing code that’s doing it’s job is one thing, making sure it is understandable and maintainable by yourself and other developers in your team is essential to keep the ability to deliver business requirements in a timely fasion.

It did not take me long to sign up after I saw Java Usergroup Utrecht, together with my old customer Rabobank, posting 2 meetups with Uncle Bob. One is about Clean Code, the other one is about Clean Architecture. After I was confirmed, I checked with my employer, who thought it was no problem at all to attend. Normally I do this the other way around, but I reckoned this would sell out really quickly. Turned out I was right. There were 400 slots for each day, with a big waitlist eager to jump in if someone could not make it.

In this blog, I share what I have learned on these two very interesting days.

Custom CloudWatch Metrics in Python? Yes we can!

5 februari 2019 Milco Numan

Introduction

Currently, AWS has three associate level certifications: Solutions Architect, Developer and SysOps Administrator. In 2017, I have passed the certification exams for the first two certifications and as I visited AWS re:Invent in Las Vegas last year, I decided that I would like to also pass the one that is missing from my curriculum right now.

On Course For Certification

One of the ways to prepare for the AWS Associate certifications (apart from reading the documentation), is completing one of the many courses being offered on the on-line learning platforms. For my first two certifications, I used the certification training offered by A Cloud Guru which were very good. However, in the meantime I have also completed some trainings on the Udemy Platform by Stephane Maarek on miscellaneous topics related to Amazon Web Services (CloudFormation Masterclass, AWS Lambda and the Serverless Framework) that I also like very much, so I decided to start my certification course with Stephane’s wonderful “Ultimate AWS Certified SysOps Administrator Associate 2019” (quite a mouthful, but it’s a 17 hour journey).

Specific Integrations

Specific Integrations

This is the sixth blog in a series of 6 blogs about integration 2.0. Did you miss one blog, read the fifth blog Services!

The API- and Event hub may support most of the integration needs. Certain data however may require a specific approach, for instance if the size, speed or format of data requires this, or an external party demands it.

This is the fifth blog in a series of 6 blogs about integration 2.0. Did you miss one blog, read the fourth blog Integration 2.0: Interactions!

Though Integration 2.0 does not explicitly mention Services or Service Oriented Architecture (SOA) it makes a clear distinction between stateful services -services that maintain specific data – and stateless services that don’t.

Integration 2.0: Interactions

17 januari 2019 Harald van der Weel
This is the fourth blog in a series of 6 blogs about integration 2.0. Did you miss one blog, read the third blog Integration 2.0 Main Integration Concepts!

The Event and API hub are the central components in the integration landscape: In principle all communication will go through them. Besides loosely coupling EAC-s and processes it connects with other generic IT capabilities (functions) as well, like Master Data Management (MDM), Reference Data Management (RDM), Business Rule Management (BRM), Identity and Access Management (IAM) and Audit and Compliance Management. These all may provide functionality or data required by processes, EAC-s or each other. However, these services and EAC-s themselves are passive components other than publishing events that might be listened to by other components.
