20 20  === 3.1 History of runtime ===
21 21  
22 -In the last few years, eMagiz has evolved from a local, on-premises deployment platform to a cloud-first platform. At the inception of the eMagiz runtime, we provided a process that could only run locally on a (dedicated) server of clients. We refer to that as Generation 1 runtime. With the requirement to deploy eMagiz runtime in the Cloud, we updated the runtime to Generation 2, including the OSGI and Karaf framework that allowed remote running runtimes. Our next step, explained below, is then referred to as Generation 3.

24 24  === 3.2 Spring Boot framework ===
25 25  
26 -The ambition of eMagiz is to work towards serverless Cloud environments where the eMagiz runtime can be made operational. A bigger portion of our platform leverages the Spring Integration framework, and the Spring Boot framework provides the required components to form a Java-based application container that can run on Docker technology. It was, therefore, logical to migrate the existing runtime to that framework, making OSGI and Karaf obsolete. Furthermore, the Spring Boot framework provides a means to measure many more things in the context of log entries and runtime metrics.

28 28  === 3.3 Docker technology ===
29 29  
30 -A more modern technology than traditional servers is using Docker containers. Docker provides containers that mimic servers in a specific way. A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another. A Docker container image is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries, and settings.

32 -Container images become containers at runtime, and in the case of Docker containers, images become containers when they run on Docker Engine. From eMagiz, we provide images that represent the code that processes your messages. As Docker is agnostic in terms of OS, the solution can run in our cloud and on-premise on both Linux—and Windows-based servers. Containers isolate software from its environment and ensure that it works uniformly despite differences, for instance, between development and staging.

48 48  * Deployment Plan
49 - The deployment has a new option called Deploy runtimes. These steps will be part of a default plan or can be added as a separate line. Effectively, once a runtime is deployed as part of a Docker image, the image needs to be loaded and executed. That means the current image, including all flows, will be replaced with a new one. This makes the deployment simple and fast. The option means that all runtime on a machine will be deployed in minutes.

Now, the properties are made part of the Docker image. That results in the necessity of creating a new release once a property is changed.

69 -** Default error handling -> eMagiz will receive the errors and show them in the Manage Dashboard
70 -** Custom error handling -> We have two separate options that allow you to send the error message to a custom solution and eMagiz or only to the custom solution.

81 81  * Handling local file communication
82 - As our third-generation runtime uses Docker technology, your containers are, by default, closed off from their host. This makes them more secure, but it also means that additional configuration is needed when interaction needs to happen between the host and the deployed containers.
