AMIS, Data Driven Blog – Oracle & Microsoft Azure
Getting value from IoT, Integration and Data Analytics
I like to do presentations about a lot of topics. Most of these presentations are recorded and the link to that recording is then shared to people who couldn’t attend the presentation live. Up to now I used bitly.com to shorten my URLs. Last time that I used bitly I […]

0 In this blog, I will show how you can use the SAM (Serverless Application Model) to get a presigned upload URL to AWS S3 that can be used exactly once [1]. In AWS it is possible to use a presigned URL to upload files, but the URL is valid for […]

0 0 It is the end of the year: time to look back, time to look forward. In the past year, I had a lot of extra time because of the Corona measures. I spent most of that time creating blog articles about AWS, starting with a series about the AWS shop […]
0 0 In June I wrote a blog series about the AWS Shop Example. In this series, I also wrote about X-Ray [1]. I like X-Ray: you can see how much time each step in a whole concattenation of AWS services takes and how much time it costs to send the response […]
0 0 Crucial pieces of functionality in cloud native applications is implemented in Functions. In the case of Oracle Cloud Infrastructure specifically, the Functions framework is typically Project Fn and the implementation language of choice is … up to the DevOps team. Popular languages for implementing Functions include Go, Python, Java and […]
0 0 Introduction We are in production with our shop example [1]. We’d like to get some statistics about our implementation: how often are the Lambda functions called? How fast are they? Of course, we could use the statistics from the performance test, but there is a faster way. This faster way […]
0 0 Introduction Our shop example [1] is now in production, wohoo!!! When you are using our example program in production, you might see that some sales are updated multiple times in the database. This will not happen very often, but you want your sales to be processed once, not twice. In […]
0 0 Introduction When you follow along in this series [1], you might have been irritated by the amount of work to test your functions. It isn’t a problem to test only the unit test for the accept function, but when you have to test the unit test for the decrypt function, […]
0 0 Introduction In the previous blog, I talked about unit tests of the AWS Shop example [1]. Today, I will continue with a smoke test and a performance test. Smoke test When you follow along, you will have seen the smoke test several times: we used a smoke test from the […]
0 0 Introduction In the last six blogs [1], I showed you an application that used AWS to process the sales from a cashing machine. This series continues with tests for this application. Some objects of our solution cannot be tested: we cannot test the API gateway, the SNS topics or DynamoDB […]
0 0 Introduction You might have noticed that we skipped the API Gateway up to now [1]. I will write two blogs about the API Gateway. In this one, we follow the simplest route: from sending the message to the API gateway, and let the API Gateway deliver the message at the […]
0 0 Introduction The ultimate goal of our shop application [1] is to update the AMIS-shop table in the DynamoDB service. In this blog, I will tell a little bit more about DynamoDB. DynamoDB is the NoSQL solution of AWS. The way we use this table in our example is straightforward: the […]
0 0 Introduction In the previous blog [1], I wrote about an example shop application in AWS. Let me show the AWS architecture of this shop again: In this blog, I will tell a little bit more about the Lambda functions in this shop example. Lambda functions are serverless functions: you don’t […]
0 0 Introduction I have to admit: I love serverless. Serverless computing is using the cloud as it is supposed to be used: it scales up when you need more capacity, it scales down to zero when you don’t need resources. That is really good when you have, for example, a shop […]
0 0 Project Fn is an open source framework for creating and running serverless functions. Project Fn produces a Docker container image for each function. This container has a runtime (for example for Java, Go, Python, Node) and a minimal handler to handle an HTTP request and turn it into a call […]
0 0 Functions on Oracle Cloud Infrastructure are implemented using Project Fn. A function runs in Docker container. This container has a runtime (for example for Java, Go, Python, Node) and a minimal handler to handle an HTTP request and turn it into a call to the function. When writing the code […]
0 0 Oracle Cloud Infrastructure API Gateway makes it possible to expose OCI Functions on public endpoints that do not require complex signed HTTP requests. Any function that should be easily publicly accessible can be given such easy access. By creating an API Deployment on an API Gateway and associating a route […]
0 0 When developing microservices, a fast startup time is useful. It can for example reduce the amount of time a rolling upgrade of instances takes and reduce build time thus shortening development cycles. When running your code using a ‘serverless’ framework such as for example Knative or FnProject, scaling and getting […]
0 0 This article highlights a use case implementation I recently implemented (for a demo session) leveraging Oracle Functions as well as OKE (Oracle Kubernetes Engine), Object Storage and Elastic Search. I will briefly touch upon some of the interesting aspects of implementing this case. The code for the function and […]
0 0 Oracle Functions is currently in limited preview and is expected to soon reach wider availability. Rolando Carrasco did this write up on Medium about his first experiences with Oracle Functions. Oracle Functions is a managed PaaS service, based on Project Fn. It supports a serverless architecture with light weight functions […]
0 0 Project Fn is an open source project that provides a container native, poly-language, cloud agnostic (aka run on any cloud) serverless platform for running functions. Fn was launched during Oracle OpenWorld 2017. Fn is available on GitHub (https://github.com/fnproject/fn ) and provides all resources required to get started. In this article, […]
