1. Develop Cloud Native Applications The prerequisite of being able to deploy through a fully automated pipeline is to have cloud native applications. Those applications are stateless: they don’t keep state within the application, but use services to keep state (Cache, RDBMS, NoSQL). Stateless apps can easily be switched out during a deployment. You can […]
My latest course is all about scaling applications on-premise and in the cloud. Let me explain in just a few paragraphs why you would want to make your application scalable and how you would do it: Making your app scalable will always reduce costs Everyone understands that you can scale when needing more resources, but even […]

Microservices The traditional monolithic application architecture is easy to develop, test, and deploy. Unfortunately those applications tend to become large, complex, and as a team it’s difficult to work together on the app. Big applications tend to intimidate developers and it also increases coordination within a team. When deploying, monolithic applications have a higher risk […]
Platform as a Service (PaaS) is a good way to focus on the app, rather than the infrastructure. At Heroku you can deploy your application in a few steps, without touching and maintaining the Operating System. You can focus on developing your application: you push the app to your code repository, and when you are ready to […]
The operational cost of Applications The big operational cost of applications is maintenance. Low and Medium security updates are often applied on a weekly or monthly basis. High and Critical updates are expedited, which means they’re are often implemented during out of hours and weekends. Next, after a couple of years running the application, the […]
1. Cloud Storage Use Cloud Storage as your Data Lake. Anonymize your data or use encryption to satisfy the policies to move your data outside the enterprise. Storing 1 TB in a European Amazon Datacenter is as cheap as $30 per month. 2. Processing as a Service You can either run open source software on […]
Free Cloud For Everyone Every Cloud provider wants you to sign up for their services. To do that, they will offer you some free services. Amazon for instance has the Free Tier. Google Cloud will give you $300 for a free trial. Heroku will give you free dynos. They’re doing this for one reason: once […]
“The cloud is not secure enough” Maybe you are scared to deploy your applications on public cloud, because you think it is less secure. You rather want everything on-premise, because you think you don’t have to think so much about security. You are wrong. Most attacks will happen on other levels (e.g. Application Level), and […]
