The difficult question is not whether to modernise, but which applications to change first without creating outages, budget surprises or an unmanageable backlog.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Azure Container Apps offers a practical middle ground. It runs applications in containers, which are portable packages containing the application and everything it needs, while Microsoft manages much of the underlying infrastructure. Your team can gain flexible scaling and faster deployments without having to operate a complex Kubernetes platform.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Azure Migrate provides the estate-level view: what you have, where it runs, what it depends on and how ready it may be to move. GitHub Copilot modernization then works closer to the application code, helping developers assess, update, containerise, test and deploy supported applications.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why moving every VM directly to Azure is not enough<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A straightforward VM migration can be the right first step when a data centre exit has a hard deadline. However, moving an ageing server into Azure without changing the application can also move the same patching burden, security exposure and wasted capacity into a new monthly bill.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The application still depends on an operating system. It may continue running at full size overnight, even when nobody is using it, and releases may still require manual changes to a long-lived server.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Container Apps changes that operating model. The application is packaged separately from the server and can scale according to demand. New versions can be deployed as revisions, allowing teams to test a release and gradually direct traffic to it rather than performing a high-risk replacement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This does not mean every VM should become a container. Windows-specific applications, tightly coupled legacy systems, products requiring persistent local storage and vendor-controlled software may be better suited to Azure VMs, Azure App Service or another platform.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Use Azure Migrate to build the business case first<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Modernisation projects often begin with an incomplete spreadsheet. It lists server names and operating systems but does not explain which applications are business-critical, who owns them or what will break if one component moves without another.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Azure Migrate helps create a more useful inventory by discovering workloads, assessing readiness and highlighting dependencies. For supported web workloads, it can help identify Java applications running on Apache Tomcat and .NET Core web applications that may be candidates for Azure Container Apps.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The important output is not simply a green or red readiness score. Decision-makers need answers to practical questions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Which applications are expensive to keep on dedicated VMs?<\/li>\n<li>Which systems have manageable dependencies and a clear business owner?<\/li>\n<li>Which applications require code changes before migration?<\/li>\n<li>Which workloads have security or support risks that make delay expensive?<\/li>\n<li>Which applications can deliver an early, visible result?<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This assessment should sit within a secure Azure foundation covering identity, networking, policies, logging and cost controls. Our guide to moving from a migration factory to a secure Azure landing zone explains why this foundation needs to be established before migration waves accelerate.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Use Copilot modernization as an assistant, not an autopilot<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">GitHub Copilot modernization is designed to analyse application code, configuration and software dependencies. It can produce a modernisation plan, suggest framework upgrades, identify cloud compatibility issues, generate container files and help prepare Azure deployment resources.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For Java applications, it can also combine AI guidance with established code transformation tools to automate repeatable changes. For .NET applications, it can assess migration readiness and assist with Azure-specific updates involving identity, storage, databases and deployment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The business benefit is speed. Developers spend less time manually searching thousands of lines of code for outdated libraries or infrastructure assumptions. They can focus their attention on business logic, testing and decisions that require organisational knowledge.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, Copilot output still needs human review. An AI assistant does not know that an undocumented file export supports month-end reporting, or that a database connection is restricted by a contractual requirement. Every generated change should pass normal code review, security scanning and testing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Create migration waves based on risk and value<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Moving applications in waves is safer than selecting the largest or most visible system first. A sensible first wave normally includes a small number of applications with clear owners, reliable source code, automated tests and limited external dependencies.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An illustrative roadmap might look like this:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Discover:<\/strong> Use Azure Migrate to build the application and dependency inventory.<\/li>\n<li><strong>Assess:<\/strong> Combine infrastructure findings with code-level analysis from Copilot modernization.<\/li>\n<li><strong>Decide:<\/strong> Classify each application as retain, retire, move to a VM, move to another managed service or modernise for Container Apps.<\/li>\n<li><strong>Pilot:<\/strong> Containerise one low-risk application and validate cost, security, performance and support processes.<\/li>\n<li><strong>Scale:<\/strong> Reuse the successful patterns across later migration waves.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Consider a 200-person organisation operating 30 internal applications across 18 virtual machines. Rather than containerising all 30, it might identify six web applications with predictable dependencies and high maintenance effort.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Starting with two of those applications gives the team room to prove deployment, monitoring, rollback and support procedures. The result is not just two migrated applications. It is a repeatable delivery pattern that can lower the cost and risk of the remaining roadmap.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Plan operations before switching production traffic<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A successful deployment is not the same as a supportable production service. Before cutover, decide who receives alerts, how teams view logs, what happens when an application scales unexpectedly and how quickly a faulty release can be reversed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Container Apps supports revisions and traffic splitting, which can reduce release risk. Managed identity, which lets an application access approved Azure services without storing passwords in its code, can also remove a common security weakness.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Logging requires particular care because moving away from VM-based monitoring can create gaps in dashboards, alert rules and historical data. See our practical guide to migrating Azure Container Apps logging to Azure Monitor safely.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You should also confirm backup requirements, data residency, vulnerability scanning, network access and alignment with the Essential Eight, the Australian Government\u2019s cybersecurity framework that many organisations use as a baseline for reducing cyber risk.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Measure outcomes that the business can see<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A migration roadmap should not be judged by the number of containers created. Track outcomes such as infrastructure cost per application, deployment time, patching effort, recovery time, security findings and the number of releases that require after-hours work.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some applications will save money by scaling down during quiet periods. Others may cost about the same but deliver faster releases, simpler recovery and less operating-system maintenance. Both can be valid outcomes if they support a clear business priority.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The best roadmap combines Azure Migrate\u2019s estate view with Copilot modernization\u2019s code-level assistance and experienced human oversight.
