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!

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

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.

Services

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

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.

Integration 2.0: Main integration concepts

This is the third blog in a series of 6 blogs about integration 2.0. Read the first blog Integration 2.0 and second blog Integration 2.0:Introdution!

EAC-s may be integrated through their standard interfaces. API-s are centrally exposed to the enterprise though an API-hub. Events are exchanged from publishers to subscribers through an Event-hub.

These recent developments have urged us to define a new Integration approach, that we call “Integration 2.0”. This approach aims to address the challenges posed by the technical and business developments for the next decade.

AWS re:Invent 2018 – mostly serverless

Where we’re going, we don’t need servers!

One of the best soundbites I read during the week of re:Invent, was on the t-shirts of one of the vendors right there … (see the title of this section). I cannot recall which one it was and I must confess that I just put all my summer clothing in storage. Anyway, going serverless is one of the big trends and for me, as an integration consultant, this is the most natural fit for moving into the cloud,

AWS re:Invent 2018 – new launches

The Event

In the first part of my blog I commented on Las Vegas itself and my experiences travelling to Las Vegas; in this part I will describe my experience with the actual reason for travelling to Las Vegas, viz. attending the AWS re:Invent 2018 event.

As you may already know, re:Invent is the yearly conference from Amazon Web Services (AWS), this time its seventh edition, held in Las Vegas, for customers, partners and vendors from the AWS ecosystem. The size of re:Invent is astonishing, during this conference (starting on Monday and ending around noon on Friday), it welcomes 53,000 participans, spread across 7 different venues for a total of over 2,200 sessions of content.

Las Vegas, or Tinseltown in the Desert

Sin City

This weekend I have returned from visiting my first AWS re:Invent. This seventh edition was (as always) held in Las Vegas – aka Sin City as it caters for the many vices people may pursue. Needless to say I have been a good boy and only indulged into drinking a few beers …
