 Hi, I am Gregor Hohpe, co-author of the book Enterprise Integration Patterns. I like to work on and write about asynchronous messaging systems, service-oriented architectures, and all sorts of
enterprise computing and architecture topics. I am also an Enterprise Strategist at
AWS.
TOPICS
I call my collection of blog entries "ramblings" because they are based on my personal opinions and observations as opposed to official "articles". The topics cover a variety of topics, ranging from integration, messaging, and conversation patterns to enterprise architects and architecture, events I spoke at as well as patterns and writing. My blog posts related to IT strategy, enterprise architecture, digital transformation, and cloud have moved to a new home: ArchitectElevator.com.
These are my Ramblings on Cloud. See all Ramblings.
Serverless Loan Broker @ GCP May 20, 2022
Do serverless solutions lock you in? Let's find out by porting / rebuilding the Serverless Loan Broker on top of Google's Cloud Platform (GCP). Read more » Infrastructure as Code (IaC) brings repeatability into the provisioning and deployment of cloud applications. However, the vocabulary used by most automation tools describes cloud platform resources as compared to the application's intent. As serverless applications take us further away from the infrastructure, we should also find better abstractions to express our automation. Perhaps, Enterprise Integration Patterns give us a head start? Read more » Serverless Loan Broker @ AWS, Part 4: Automation November 30, 2021
Infrastructure as Code (IaC) has a whole new meaning for serverless applications. Rather than provision resources (the serverless frameworks do that for us), automation determines the system composition and configuration. As expected, quite a few options are available from simple command line to programming frameworks. Time to have a look. Read more » Part 3 of the mini-series on implementing the EIP Loan Broker as a serverless solution with AWS Step Functions uses a Publish-Subscribe Channel and a stand-alone Aggregator to request and process loan quotes. Read more » Loan Broker @AWS, Part 2: Recipient List July 20, 2021
In part 2 of this blog series I implement the Loan Broker Example using a Recipient List pattern, implemented in DynamoDB, Step Functions, and Lambda. Read more » Loan Broker Implementation with AWS Step Functions July 20, 2021
A lot has happened since we implemented the Loan Broker Example in EIP: we have the cloud, serverless computing, machine learning, service meshes and all sorts of other bells and whistles. Nevertheless, the integration patterns have passed the test of time as we shall see by implementing the original loan broker example with AWS Lambda and AWS Step Functions. Read more » Serverless Integration Patterns on Google Cloud Functions April 20, 2017
After examining which patterns are embedded in Google Cloud Pub/Sub in an earlier post, I implemented a few common patterns on top of Google Cloud Functions, Google's serverless implementation. It's amazing how easy it has become to get messaging patterns running in the cloud with only a minimum of wrapper code. Read more » Virtualization Matryoshka July 15, 2015
IT loves virtualizing stuff, following the old rule that in computer science every problem can be solved by just one more level of indirection. Cloud computing is based on virtualization of compute resources - you don't need to know which machine your application is actually running on and you can get new ones with the click of a button. Before cloud was a buzzword, though, VMware and others have virtualized machines at the operating system levels. Recently (in terms of buzz, not technology), containers bring another level of light-weight virtualization of resources. And let's not forget the Java Virtual Machine, which also claims a level of virtualization. What are we supposed to do with all these levels of virtualization? Read more » Google Cloud Pub/Sub APR 8, 2015
Google released the beta version of their publish-subscribe API just a few weeks ago. I show how to build a very simple demo app using the Java API and map the functionality to integration patterns to illustrate the design choices the team made.

I joined JavaOne this year as a panelist on Cloud Computing. Here my belated impressions on this year's JavaOne. Read more » |
