Video Series: Modernizing Java Apps for Developers Part 5

Moving a monolithic application to a modern cloud architecture can be difficult and often result in a greenfield development effort. However, it is possible to move towards a cloud architecture using Docker Enterprise Edition (EE) with no code changes and gain portability, security and efficiency in the process. To conclude the series In part 5, I use the message service’s REST endpoint to replace one part of the application UI with a Javascript client. The original application client UI was written in Java Server Pages (JSP) so that any UI changes required the application to be recompiled and redeployed. I can use modern web tools and frameworks such as React.js to write a new client interface. I’ll build the new client using a multi-stage build and deploy it by adding the container to the Docker Compose file. I’ll also show how to Continue reading…

Video Series: Modernizing Java Apps for Developers Part 4

Moving a monolithic application to a modern cloud architecture can be difficult and often result in a greenfield development effort. However, it is possible to move towards a cloud architecture using Docker Enterprise Edition (EE)  with no code changes and gain portability, security and efficiency in the process. Part 4 takes advantage of the messaging service I added in part 3. In this installment, I’ll add self service analytics powered by the open source Elasticsearch / Kibana stack. The reporting database and analytics UI run in containers and the worker is updated to also store data in Elasticsearch. The Docker platform supports adding new components to a running deployment without shutting down the application containers that are currently running. You’ll learn how Docker lets you add new capabilities to the application with zero downtime in production. Docker MTA Video Series: Modernizing Java Continue reading…

Video Series: Modernizing Java Apps for Developers Part 3

Moving a monolithic application to a modern cloud architecture can be difficult and often result in a greenfield development effort. However, it is possible to move towards a cloud architecture using Docker Enterprise Edition with no code changes and gain choice , security and operational agility in the process. Part 3 of the series begins the modernization process. I’ll take one aspect of the current application and break it out into a microservice. As written, the application writes to the database directly, but direct writes to the database can easily overwhelm the application by a large number of requests. One solution is to implement a messaging queue. As in the part 2, I’ll follow several guidelines: Leave existing code in place. Design the new code as a separate and reusable application Deploy the microservice locally using Docker Enterise Edition Test the code In this Continue reading…

Video Series: Modernizing Java Apps for Developers Part 2

Moving a monolithic application to a modern cloud architecture can be difficult and often results in a greenfield development effort. However, it is possible to move towards a cloud architecture using Docker Enterprise Edition with no code changes and gain portability, security and efficiency in the process.   In the first post in this series, we discussed how you don’t need to do a full re-architecture of your application to microservices when using Docker Enterprise Edition. In the second installment of the series, I go into the details of containerization of the application. This process builds containers using the application code as-is. I’ll follow three simple rules: Keep the existing architecture Keep the save version of the OS, components and application Keep deployment simple, i.e. static not elastic I’ll also demonstrate how to use multi-stage build file to compile the code and deploy it to application Continue reading…

Video Series: Modernizing Java Apps for Developers Part 1

Moving a monolithic application to a modern cloud architecture can be difficult and often result in a greenfield development effort. However, it is possible to move towards a cloud architecture using Docker Enterprise Edition with no code changes and gain portability, security and efficiency in the process. Containerizing a monolithic application is a great starting point for modernizing application architecture.In many cases this can be done with no code changes at all.  From there, breaking down the application into smaller components makes it easier to deploy updates, introduce new components and manage scale. This new video series covers modernization for Java applications. It walks through the process of evolving a N-tier Java application to a distributed application running across multiple containers. Docker provides the platform that plugs in and manages all the components into a coherent architecture. This  series does not cover Continue reading…

Video Series: Modernizing .NET Apps for Developers

 Docker Enterprise Edition (EE)  is the container platform for modernizing your existing applications, and running them in the cloud or on-premises. You can take monoliths and run them in containers with no code changes, and that gets you portability, security and efficiency. Running in Docker is also a great starting point for modernizing the application architecture. You can breaking down the monolith into smaller, independent components which makes it easier to deploy updates, manage scale and introduce new technologies. This new video series covers app modernization, for .NET developers and architects. It walks through the evolution of a monolithic ASP.NET 3.5 app to a distributed application running across multiple containers, using the Docker platform to plug everything together and adding features with great open-source software from the Docker ecosystem. This is not a full re-architecture to microservices – for large .NET apps Continue reading…

Cisco Now Reselling Docker Enterprise Edition

Today we are excited to announce the expansion of our partnership with the availability of Docker Enterprise Edition (EE), our container management platform on the Cisco Global Price List (GPL) and the release of the latest Cisco Validated Design (CVD): Cisco UCS Infrastructure with Contiv and Docker Enterprise Edition for Container Management Now customers can purchase Docker EE directly from Cisco and their joint resellers to jumpstart their new year’s resolution for a more modern application architecture, reduce IT costs and redirect saving to innovation projects.  And with our latest CVD for Cisco UCS compute infrastructure with secure container networking fabric, Contiv,  we’ve provided a roadmap on how to get started so customers and partners can gain a faster, more reliable and predictable implementation of Docker EE. For enterprises looking to use Docker’s container management platform but not sure where to start, Continue reading…

The Journey to 150,000 Containers at PayPal

Updated Dec 6, 2017 to clarify that the 50% boost is an enhancement for developers’ build / test workflow and complements their CI environment. PayPal developer use Docker for Mac and Docker for Windows on their local machines as part of this workflow. PayPal is committed to democratizing financial services and empowering people and businesses to join and thrive in the global economy. Their open digital payments platform gives 218 million active account holders the confidence to connect and transact in new and powerful ways. To achieve this, PayPal has built a global presence that must be highly available to all its users: if PayPal is down, the effects ripple down to many of their small business customers, who rely on PayPal as their sole payment processing solution. PayPal turned to Docker Enterprise Edition to help them achieve new operational Continue reading…
