This is a new 5-part video series in Docker’s Modernize Traditional Apps (MTA) program, aimed at Microsoft IT Pros. The video series shows you how to move a .NET 3.5 app from Windows Server to a Windows Docker container and deploy it to a scalable, highly-available environment in the cloud – without any changes to the app. Part 1 introduces the series, explaining what is meant by “traditional” apps and the problems they present. Traditional apps are built to run on a server, rather than on a modern application platform. They have common traits, like being complex to manage and difficult to…
Modern applications are broken up into, and advertised as smaller, decoupled microservices that can be easily scaled across large compute clusters. The microservices approach emphasizes two key architectural considerations: service discovery and load balancing. As developers build their applications to scale, they need to consider and design how each service is being discovered by other services from within or outside the cluster. Additionally, as these services scale horizontally across the cluster, they should be equally utilized for maximum load distribution.
With Containers as a Service (CaaS) IT organizations and developers can work together in a secured and managed application environment to build, ship and run their applications anywhere. In last week’s blog post, we introduced Containers as a Service and discussed how it can provide a modern platform. In this post, we discuss in more detail the characteristics that uniquely power CaaS. The reason developers don’t adopt locked down platforms is because software development is an exercise in both discovery and creation. It is critical to keep this in mind when considering application platforms.
Developers don’t adopt locked down platforms. That one simple statement summarizes decades of tension between IT operations and development teams. Along the spectrum of control versus agility are the desires and needs of IT operations teams responsible for keeping environments up and running and compliant to regulations and the needs of developers who are responsible for building software to attract, engage and maintain customers. Most times you had to choose between control or freedom and could not have both.
