What's wrong with the legacy monolithic architecture of Windows applications?

  1. Typically, the core business logic of a legacy monolithic application is tightly coupled to its GUI.
  2. Legacy applications may not scale well enough to meet new customer needs, resulting in decreased performance and increased customer frustration.
  3. Developers often get stuck in old code when there are so many exciting new technologies available to innovate.
The good news is that moving from a legacy desktop application to a microservice architecture stops the monolithic nightmare.
Dividing a monolithic application into subsystems that can be scaled, developed, and deployed individually is your entry point into the microservices realm.

Docker containers.

Docker is currently the leading container toolbox to deploy microservices to the cloud.

A software container packages the code, its libraries, frameworks, and other dependent components. As a result, the application runs quickly and reliably in any environment, be it a local data center, a public cloud, or a developer's laptop.

Software containerization solves many of the challenges of software development and deployment, so we embraced this concept when moving our Windows desktop applications to the cloud.

The most suitable types of software to embed in a docker container are non-user interface applications that are run from the command line. Typically Linux-based Docker images are lightweight and widely used in cloud environments.

Unfortunately, in most cases, rewriting all of your Windows application code from scratch to make it cross-platform is too expensive and time-consuming.

Besides, when it comes to platform design, sharing the kernel between Dockerized applications has significant limitations. For example, Windows containers will not be able to run on a Linux host.

Windows container base images.

Microsoft offers Windows containers to deliver containerized services on the Windows platform.

Check out a good article from Microsoft that describes Windows docker container images that users can build from.

I will use an InsiderWindows Server Core image as a base. This image includes a subset of the Windows Server APIs and is suitable for packaging typical .NET framework applications.

  • Insider images are >50% smaller than the .Net Framework Runtime Images.
  • Container startup into Windows PowerShell is 30-45% faster.

Dockerizing DBConvert tools.

As an example, I will show how to build a Docker image for DBConvert Studio. It is a classic .NET Windows application running either in GUI mode or in headless mode from the command line. It is also a good source of Docker-related techniques if you want to customize your own Dockerfiles further.

Let's dive deeper into what the Dockerfile actually does.

  • The first FROM line pulls the Insider Windows Server Core image.
  • The next RUN simply displays the status of the following ADD command. It downloads the installation zip package directly to our new image.
  • COPY DBConvert-Studio.reg / command copies the DBConvert registration file info to the root of the image. We will use it later to remove all restrictions on the DBConvert studio unregistered copy of the. (See the reg import command, which will appear later).

Let's take a look at the rest of the PowerShell commands combined into the following RUN command.

  • The Write-Host command displays the current status of the operation.
  • Expand-Archive - extracts the contents of the newly downloaded zip archive to the root directory of our image.
  • Start-Process msiexec command installs the unpacked archive.
  • The next 'Start-Process reg' command imports the registration file's contents into our docker image's Windows registry.
  • Remove-Item removes all unnecessary intermediary files from the final image.
  • Set-Location sets the specified location as a working directory.
  • CMD ['powershell'] specifies what command to run within the container. In fact, we can call straight CMD ['DBConvert.exe', '/ Session:', 'mysql2mysql'] , but each time it may be a different session configuration file. Therefore, it is better to bind the directory on the host to the directory inside the container with the --volume (-v) flag

Building Docker image and starting container.

Launch the following command in the terminal to build your Docker image.

Install docker to windows server 2016

The next command docker run starts a container from the newly created DBConvert Studio image.

Containers are immutable in design. This means that the container will not be changed during its life cycle: no updates, no patches, no configuration changes.

When starting DBConvert studio from the command line, you need to pass in a ready-made session file that includes the configured database connections involved in the migration and some other parameters.

-v flag mounts c:dbconvert-dockerstudioworkSettings directory on the host machine into the folder C:PROGRAM FILESDBCONVERTDBConvert Studio x64workSettings inside the running container.

  • This way we can feed DBConvert Studio with jobs located outside of the container.
  • Another advantage of directory binding is that it works and vice versa. When a process completes, a log file is generated. It appears both inside the container directory and on the host computer.

Final thoughts.

Unfortunately, there is currently no way to create new session files (jobs) outside of the DBConvert Studio GUI. The new web interface and DBConvert API functionality is included in our plans as shown here.

DBConvert's current products are Windows desktop applications. Using Docker and Kubernetes to run applications in the cloud has been gaining popularity for several years now. Following today's trends and demands, we will gradually move to the cloud and build a hybrid Windows and Linux host infrastructure.

This is the very first and obvious step of moving to a cloud environment. We are ready to help you launching dockerized DBConvert tools on your own infrastructure.

DBConvert tools are the most suitable software solutions for database administrators who need complex migration and synchronization between the most popular RDBMS, including MySQL, SQL Server, Oracle, PostgreSQL, and many others.

Recently Microsoft released Windows Server 2016 and supported docker natively. This article takes a series of steps to learn how to install docker in Windows Server 2016.

Windows supports two different types of containers, namely Windows Server container and Hyper V container. Both types of containers use the same way and support the same container image. But their implementation mechanisms are different, providing different levels of security isolation

Windows Server Containers – Very similar to containers in Linux, process isolation is achieved through namespace and resource control. Each Windows Server container shares the same kernel with the host.
Hyper V Containers – Each container runs in a highly optimized Hyper V virtual machine, so the container has a separate kernel. In this way, the isolation of the container will be better, but the start-up speed will be slower, and its resource occupation will increase.
If you don’t have a Windows Server 2016 environment at hand, we can also start the experiment with Docker for Windows on Windows 10.

Here are some tips from Docker’s Chinese Guide:

Tip 1: Docker has been tested on Windows 7.1 and 8, but it can also be used on low-level windows. But your processor must support hardware virtualization.

Tip 2: Docker engine uses Linux kernel features, so we need to use a lightweight virtual machine (VM) on Windows to run Docker. We use Windows Docker client to control the construction, operation and management of Docker virtualization engine.

Tip 3: To simplify this process, we designed an application called Boot2Docker, through which you can install virtual machines and run Docker.

Tip 4: Although you are using Windows Docker client, the docker engine container is still running on the Linux host (now through Virtual Box). Until we develop the Windows version of the Docker engine, you only need to start a Linux container on your Windows host.

Basic requirements for Windows docker installation environment:

(1) Must be a 64-bit operating system, win7 or higher (Windows 10/server 2016 is recommended because the new version integrates many new components)
(2) Support “Hardware Virtualization Technology” and “virtualization” is available (that is, enabling VT parameters in BIOS)

1. Download Windows Server 2016 180-day evaluation version.
