HTTP and connection pooling
HTTP is used heavily in many microservices architectures. While there are other options to increase the performance, if you conclude HTTP is the way to go, looking into using persistent connections might save your day. If the server supports persistent connections, HTTP connection pooling can provide performance benefits when multiple HTTP requests target the same

The major public Cloud platforms are playing a special kind of land-grab. As a result, ever more resources are made available closer to ever more customers. These resources are available to anyone, instantly, based on micro-billings for time reserved or actual use. All you need is a creditcard. It’s the ultimate form of self-service backed
Lees verderBuilding serverless APIs using AWS services
Lately I’ve been talking on a few occasions to peers and customers about how to build serverless Web APIs using AWS. The key objective of this talk is to discuss different kinds of communication patterns and how we can implement these using AWS services. Since then I have received several requests to share the slides,
Lees verderCloud Strategy: Cloud or Clouds?
Vendor lock-in is a concern when moving to the Cloud. Depending too much on anything is a risk and relying on Amazon, Google or Microsoft is no different. What if they go out of business? No one expects that to happen any time soon, but unexpected things happen. It is just something to think about
Lees verderFirebase: Cloud voor frontend developers
Bij Profit4Cloud hebben we het nogal vaak over de Cloud. Maar we hebben niet alleen Cloud-fanatici. Onder ons zijn ook frontend developers die zich vooral bezig willen houden met het bouwen van apps d.m.v. JavaScript, HTML en CSS. Toch heb je bij het maken van een app meestal ook een backend nodig. En dat is

Softwareontwikkeling gaat in de basis over het vertalen van wensen in software; een creatieve vorm van probleemoplossing waarbij een gestructureerde aanpak en intelligentie helpt, trouwens ook geduld en doorzettingsvermogen voor het geval dat het niet meteen lukt. Hier verandert helemaal niets aan. Wat wel steeds verandert is hoe we onze oplossingen implementeren. Ons vak is
Lees verderAsync API with API Gateway and the SQS Alternative
In the previous blog post, we showed how we can create an async API by configuring API Gateway to transform and publish requests directly to Amazon Simple Notification Service (SNS). The great thing about SNS is that SNS can trigger a Lambda function by publishing messages to topics. These functions act as worker to do
Lees verderAsync API with API Gateway and SNS
When discussing the implementation of a asynchronous API on AWS the first solution that came to mind (at least to mine) was to use API Gateway, two Lambda’s and a queue (or actually a SNS topic). ‘2-lambda’ solution The first Lambda function would be configured to receive the request from the API Gateway and publish
Lees verderSecure serverless with Lambda breaks the rules?
AWS Lambda lets you just run code without provisioning or managing servers. Its execution is triggered by an event. An example of the supported AWS services that you can configure as an event source is API Gateway. This allows for triggering a Lambda function over HTTPS by configuring an endpoint in the API Gateway. When a HTTPS

AWS Lambda pioneered serverless compute offerings. With serverless compute we don’t need to know about the underlying servers that ensure that our application is always on (available) and scaled to match the current load. No need, but that doesn’t mean that I don’t want to know. Consulting the official docs Curious about the inner workings

Everywhere I go people are either thinking about moving to the Cloud or evaluating their first steps and debating what their next step should be. (Ok, so given what we do at Profit4Cloud that is not like a representative sample of what goes on in companies all the time; they probably have a business

Ok, so you want to program your AWS Lambdas in Java and use Spring? You have a few options, such as using Spring Cloud Functions or the AWS Serverless Java Container project by AWSLabs. Both of these projects are interesting in their own way; The first tries to save us from vendor lock-in by abstracting

Afgelopen donderdag hebben we onze eerste Profit4Cloud Tech Update van 2018 verzorgd. Met zo’n 50 aanwezigen, die ondanks ‘code rood’ toch de weg naar ons kantoor wisten te vinden, prima eten en een gezellige borrel kijken we terug op een geslaagd evenement. Op verzoek ook links naar de presentatie en de gebruikte sources.

Vorige week vond de “Google Cloud OnBoard” training plaats op de High Tech Campus in Eindhoven. Een complete dag georganiseerd door Google om engineers te interesseren voor hun Cloud-platform. Het was, zoals de naam al zegt, een training voor beginners om kennis te maken en de mogelijkheden te zien. Ze begonnen dus, uhm, bij het
