Refactoring Legacy Windows Applications

There should be no doubt anymore that containers are revolutionizing the world of application development and leading the charge for purpose-built cross-cloud and hybrid-cloud topologies. There are other virtualization platforms that solved problems in server consolidation and data center optimization, but in the new world of cloud and mobility, proprietary monolithic middleware may have had its day. Most technophiles think of Docker and Kubernetes as the realm of DevOps, analytics, and IoT and not for your legacy .NET applications that your business has run on since the early 2000s, right?

Increasingly, businesses are looking at legacy workloads that still provide value to the company, trying to determine whether to spend the cycles on maintaining status-quo, upgrading code, complete overhauls of applications, or complete shifts in platforms. All of these options take time and resources and may never have an ROI based on the time those legacy apps will be of value to the company. In many cases, the source code is not available, and the original developers have moved on or out of the company. Unfortunately, many companies just keep legacy workloads running on legacy systems, using legacy infrastructure and tools – all of which cost quite a bit in equipment and people, not to mention care and feeding.

Until recently, these workloads did not seem to be a good choice for migrating into containers due to the overall size of containerized windows environments vs. the density of Linux-based systems. On the surface, hypervisor-based virtualization has been the primary choice for limited-use Windows applications near the end of their lives. However, as many companies are trimming down the consumption of on-prem licensing and CAPEX hardware and adopting cloud-first strategies, choices in cloud providers can be limited – or at least relegated to expensive options – if proprietary VM formats are the only choice.

CloudHedge has solved this problem with automated container migration and conversion for legacy windows applications. Through this process, the workload can be trimmed down to the minimum footprint and optimized for a container environment – all without touching the code. In this new format, these legacy workloads can run on-prem when being used, and easily managed through Kubernetes to archive into nearly any cloud environment where costs can be constrained. Ideally, the cost savings in migration and optimization save time, and allow resources to be focused on modernization and transformation, rather than simply encapsulating old processes.

It’s a slightly complicated process than you think it is. Whether you are setting up a new container environment in your infrastructure or implementing a hybrid-cloud or cloud-native microservices initiative, CloudHedge can do the heavy lifting for you to set it up. Once your environment is ready, CloudHedge will then refactor your applications for optimal performance, security, and mobility – allowing you to focus on operations through the use of CloudHedge’s microservices automation platform. It surely eliminates a manual approach and puts you on an automated track, however, there is minimal human supervision to ensure the process goes smoothly.

Furthermore, CloudHedge brings a team of experienced, proven cloud and microservices architects and consultants who will help to identify, design, and implement optimal migration strategies for your business. Whether the right choice is on-prem, public cloud, private cloud, or a mix of each, CloudHedge tools can handle critical tasks of refactoring and containerization, allowing you to execute your best path for modernizing, securing, and mobilizing your legacy workloads.
